Modularity and specialization

The modular production of plastic extruders can adapt to the special requirements of different users, shorten the research and development cycle of new products, and strive for a larger market share; while specialized production can arrange the production of each system module component of extrusion molding equipment at a fixed point or even for global procurement, which is very beneficial to ensure the quality of the whole period, reduce costs and accelerate the capital turnover.

 

High efficiency and multi-functionalization

The high efficiency of plastic extruders is mainly reflected in the high output, low energy consumption, and low manufacturing cost. In terms of function, the screw plastic extruder has been used not only for extrusion molding and mixing processing of polymer materials but its use has been broadened to food, feed, electrode, explosives, building materials, packaging, pulp, ceramics, and other fields.

 

Enlargement and precision

Achieving the large-scale plastic extruder can reduce the production cost, which is a more obvious advantage in the large twin-screw plastic pelletizing set, film blowing set, pipe extrusion set, etc. National key construction services required for major technical equipment, large-scale ethylene project supporting one of the three key equipment of large extrusion pelletizing unit long-term dependence on imports, so we must accelerate the localization process to meet the development needs of the petrochemical industry.

 

Intelligent and networked

Plastic extruders in developed countries have generally used modern electronic and computer control technology, the entire extrusion process parameters such as melt pressure and temperature, the temperature of each section of the body, the main screw and feeding screw speed, feeding volume, the ratio of various raw materials, motor current and voltage and other parameters for online detection, and the use of microcomputer closed-loop control. This is extremely beneficial to ensure the stability of process conditions and improve the precision of products.

underwater pelletizing machine plays an irreplaceable role in the current industrial production process. Only when the underwater pelletizing machine is used correctly can the greatest effect be achieved.

• What problems should be paid attention to when using underwater pelletizing machine?

• What is the cause of the friction clutch failure of the underwater pelletizing machine and its solution?

• How can the underwater pelletizing machine make the pellets cut out by pelletizing have no pores?

What problems should be paid attention to when using underwater pelletizing machine?

1. Pay attention to the temperature change of the underwater pelletizing machine at any time. When touching the sliver with clean hands, the temperature should be raised immediately. Until the sliver touches your hand, it is normal.

2. When the bearing part of the reducer burns, or is accompanied by noise, it should be repaired in time and refueled.

3. When the bearing parts at both ends of the bearing chamber of the underwater pelletizing machine are hot or there is noise, stop the machine for maintenance and add butter. During normal operation, add butter to the bearing chamber every 5-6 days.

4. Pay attention to the operating rules of the underwater pelletizing machine; such as: the machine temperature is high or low, the speed is fast or slow, and it can be dealt with in time according to the situation.

5. When the operation of the underwater pelletizing machine is unstable, pay attention to check whether the gap of the coupling anastomosis is too tight, and adjust it in time to loosen it.

What is the cause of the friction clutch failure of the underwater pelletizing machine and its solution?

Reason analysis: The instantaneous starting voltage of the main motor of the underwater pelletizing machine is too low, the friction disc and the friction disc are overheated, the friction disc and the friction disc are aging, and the air pressure of the friction disc is too low, etc., which can cause the clutch to disengage.

Solution: When starting the main motor of the underwater pelletizing machine, avoid peak power consumption and reduce the feeding load. The minimum restart interval is 30 minutes; in summer, when the main motor is restarted more than twice, it should be extended. Interval time or forced cooling with a fan. Blow with instrument wind and wipe off the dirt on the surface of the friction plate and friction plate with a rag. If the underwater pelletizing machine wears a lot or the surface becomes "vitrified", replace the friction plate and friction plate. Confirm whether the air pressure value can make the friction disc and the friction plate fit together.

How can the underwater pelletizing machine make the pellets cut out by pelletizing have no pores?

One: The different materials used by the underwater pelletizing machine must be separated clearly;

Two: The products produced by the underwater pelletizing machine should be dewatered as much as possible after being crushed and cleaned;

Three: The vent hole on the screw of the underwater pelletizing machine should be unblocked.

Nanjing JlEYA has various underwater pelletizing machines that can provide the increasing of products, and make them more effective, reliable, and consistent.

Degradable plastics refer to a class of plastics whose various properties can meet the requirements of use, remain unchanged during the shelf life, and can be degraded into environmentally harmless substances under natural environment conditions after use. Therefore, it is also called environmentally degradable plastic.
There are a variety of new plastics: photodegradable plastics, biodegradable plastics, light/oxidative/biodegradable plastics, carbon dioxide-based biodegradable plastics, thermoplastic starch resin degradable plastics.
There are two main areas for the use of degradable plastics: one is the area where ordinary plastics were originally used. In these areas, the difficulty of collecting used or post-consumer plastic products will cause harm to the environment, such as agricultural mulch and single-use plastic packaging, and the second is areas where plastics are used instead of other materials. The use of degradable plastics in these areas can bring convenience, such as ball tacks for golf courses, and seedling fixing materials for tropical rainforest afforestation.
Specific applications are:
1.Agriculture, forestry and fishery, plastic film, water-retaining materials, seedling pots, seedbeds, rope nets, slow-release materials for pesticides and agricultural fertilizers.
2.Packaging industry, shopping bags, garbage bags, compost bags, disposable lunch boxes, instant noodle bowls, buffer packaging materials.
3.Sporting goods, golf tacks and tees
4.Hygiene products, women's hygiene products, baby diapers, medical mattresses, disposable haircuts.
5.Medical materials, bandages, clips, small sticks for cotton swabs, gloves, drug release materials, and surgical sutures and fracture fixation materials.

• What are the reasons and solutions for the poor discharge or blockage of the single screw extruder head?

• What is the importance of single screw extruder temperature control?

• What is the importance of single screw extruder speed control?

What are the reasons and solutions for the poor discharge or blockage of the single screw extruder head?

1. Reasons: (1) A certain section of the heater does not work, and the material is poorly plasticized. (2) The operating temperature is set too low, or the molecular weight distribution of the plastic is wide and unstable. (3) There may be foreign objects in the single screw extruder that are not easy to melt.

2. Treatment method: (1) Check the heater and replace it if necessary. (2) Verify the set temperature of each section, negotiate with the technician if necessary, and increase the temperature set value. (3) Clean and check the extrusion system and head of the single screw extruder.

What is the importance of single screw extruder temperature control?

Temperature control refers to the temperature of the single screw extruder during plastic extrusion, including the temperature control of the barrel, die and transition body. These temperature controls are related to the viscosity of the material, the sensitivity to temperature, and the aggregation state of the polymer. In general, the temperature of the die head and transition body of single screw extruder is low for medium and low viscosity materials, and the temperature of die head and transition body for high viscosity materials is high, and the fluidity is good.

What is the importance of single screw extruder speed control?

Speed control means that for single screw extrude processing, if the screw speed increases, the shear rate increases. Thermoplastic melts are mostly non-Newtonian pseudoplastic fluids, and their viscosity decreases with the increase of shear rate, and fluidity Increasing the extrusion output also increases. However, if the shear rate is too large, the melt viscosity is too low, which will cause difficulties in the production and operation of single screw extrude. At the same time, the low-viscosity melt will flow backwards under the action of the screw back pressure, and the leakage flow will increase significantly, which will affect the output to a certain extent. , Again, the screw may even slip at high speeds, so the screw speed should be controlled within a certain range. In addition, in the production process of single screw extrude, the screw speed should be kept as stable as possible to avoid fast and slow. Otherwise, it will cause uneven discharge due to excessive changes in the melt viscosity of the material, which will affect normal production.

Nanjing JlEYA is a single screw extruder manufacturer established for more than five years. We work with customers from design to completion to ensure that all technical requirements are met.

The structure of the engineering plastic twin screw extruder barrel is basically similar to that of the single-screw extruder screw barrel.

What are the reasons why people choose engineering plastic twin screw extruder?

1. Improve labor efficiency

When the equipment is repaired, engineering plastic twin screw extruder only needs to loosen a few bolts, turn the worm gear box handle device to lift the upper part of the barrel to open the entire barrel, and then perform repairs. This not only shortens the maintenance time, but also reduces the labor intensity.

2. High torque and high speed

The development trend of engineering plastic twin screw extruder in the world is towards high torque, high speed, and low energy consumption. The effect of high speed is high productivity. engineering plastic twin screw extruder belongs to this category, and its speed can reach 500 rpm. Therefore, it has unique advantages in processing high-viscosity, heat-sensitive materials.

3. Wide range of applications

engineering plastic twin screw extruder has a wide range of applications and can be applied to the processing of a variety of materials

4. High output, high quality

engineering plastic twin screw extruder has other advantages of ordinary extruder, and can achieve high output, high quality and high efficiency.

What is the workflow of engineering plastic twin screw extruder?

The engineering plastic twin screw extruder used for profile extrusion is usually tightly meshed and rotated in different directions, although a few also use co-rotating twin screw extruders, generally operating at a relatively low screw speed, about 10 r/ min. The high-speed meshing co-rotating engineering plastic twin screw extruder is used for compounding, venting or as a continuous chemical reactor. The maximum screw speed of this type of extruder is 300-600r/min. Non-intermeshing extruder is used for mixing, venting and chemical reaction. Its conveying mechanism is quite different from intermeshing extruder, which is closer to the conveying mechanism of single screw extruder, although there are essential differences between the two.

What are the essential devices in the engineering plastic twin screw extruder?

Among the straightening devices used in engineering plastic twin screw extruder, the most common one is eccentric, and various types of bending of the core are one of the important reasons for the insulation eccentricity. In sheath extrusion, scratches on the sheath surface are often caused by the bending of the cable core. Therefore, the straightening device in various engineering plastic twin screw extruder is indispensable. The main types of straightening devices are: drum type (divided into horizontal and vertical); pulley type (divided into single pulley and pulley block); winch type, which has multiple functions such as dragging, straightening, and tension stabilization; Press wheel type (divided into horizontal type and vertical type), etc.

The engineering plastic twin screw extruders are used more and more widely in daily life, but its quality has a great influence on the experience of use. Nanjing JlEYA has focused on the production and development of engineering plastic twin screw extruders for more than several years, and they have always put the needs of customers as their top priority.

When the single screw extruder is in the extrusion molding process, its extruder screw is divided into 3 sections: feeding section (feeding section), melting section (compression section), metering section (homogenization section), these three sections Correspondingly, three functional areas are composed of materials: solid conveying area, material plasticizing area, and melt conveying area. Each area has different temperature requirements, and specific problems should be analyzed in detail. The temperature of the single screw extruder will be briefly introduced below.

• What is the general temperature of the solid conveying zone in a single screw extruder?

• What is the general temperature in the plasticizing zone of the material in a single screw extruder?

• What is the general temperature of the melt conveying zone in a single screw extruder?

What is the general temperature of the solid conveying zone in a single screw extruder?

The temperature of the barrel in the solid conveying zone of the single screw extruder is generally controlled at 100~1400C. If the feeding temperature is too low, the solid conveying zone will be extended, reducing the length of the plasticizing zone and the melt conveying zone, which will cause poor plasticization of the single screw extruder product and affect product quality.

What is the general temperature in the plasticizing zone of the material in a single screw extruder?

The temperature of the material plasticizing zone in the single screw extruder is controlled at 170~1900C. Controlling the vacuum degree of this section is an important process index. If the vacuum degree is low, it will affect the exhaust effect, resulting in bubbles in the pipe, and seriously reducing the mechanical properties of the pipe. In order to make the gas inside the material easily escape, the plasticization degree of the material in this section should be controlled not to be too high, and the exhaust pipe of the single screw extruder should be cleaned frequently to avoid blockage. The vacuum degree of the barrel is generally 0.08~0.09MPa.

What is the general temperature of the melt conveying zone in a single screw extruder?

The temperature of the melt conveying zone in the single screw extruder should be slightly lower, generally 160~1800C. Increasing the screw speed in this section, reducing the head resistance and increasing the pressure in the plasticizing zone are all conducive to the improvement of the conveying rate. For heat-sensitive plastics such as PVC, the residence time should not be too long in this section. The screw speed is generally 20 ~30r/min. The head of the single screw extruder is an important part of extruded product molding. Its function is to generate a higher melt pressure and make the melt shape into a desired shape. The process parameters of each part of the single screw extruder are: die connector temperature 1650C, die temperature 1700C, 1700C, 1650C, 1800C, 1900C.

This is some information related to the use of single screw extruders. The use of single screw extruders is also closely related to the quality of its products. If you need more information, please contact Nanjing JlEYA.

What are the technical points of the twin screw extruder?

Why are twin screw extruders warmly welcomed now?

The twin screw extruder can not only add more ingredients to the company's products, but also can choose to quickly complete the manufacturing. Considering that "new crown pneumonia" has put every industry into trouble, the market has been looking for a quick turnaround to pay for healthy food. In addition, you may need to make up for the loss of production and sales or increase production and sales based on the current situation. Twin-screw extension can help you, and considering the lower cost and higher production and sales, it can bring more profits.

Choose a single-screw extruder or a twin screw extruder?

The single-screw extruder is used for extrusion processing technology and equipment, and the particle raw materials stay in the extruder for a long time. This means that a single-screw extruder requires a longer period than a twin screw extruder to produce the products required by the enterprise. In addition, the twin screw extruder allows you to better control the complex operation process and actual operation. As everyone knows, these controls are much more complicated. This is very important for foods that need to be mixed and mixed. The production and manufacturing facilities are complete, and the actual effect of twin-screw extrusion is the best. For polymer materials, twin-screw extrusion is also particularly effective. Considering that the design concept of twin screw extruder has a relatively large flexibility, it can be used in many industries for very specific operation processes.

What are the technical points of the twin screw extruder?

In the extrusion process of the twin screw extruder, the material is transformed from the glass state to the molten state. In addition to the balance between the heat required for plasticization of the material and the amount of heat supplied, the material is melted. Pressure is also a very important control indicator. Because the material is affected by the compression ratio of each section of the die resistance screw during the extrusion process, it does not exist under normal pressure. For different die, the compression ratio of each section of the screw is basically constant and immutable. Under the premise of the same extrusion speed, increase or decrease the feed rate, the volume of the screw material in the feeding section will change, and the volume of the material in the exhaust section will remain unchanged, so the compression section of the feeding section changes with the compression ratio, and its melt pressure follows Increase or decrease; under the premise of the same feed rate, increase or decrease the extrusion rate, the volume of the screw material in the feeding section will also change. The volume of the material in the exhaust section remains unchanged, so the compression section of the feed section changes with the compression ratio, and its melt pressure increases or decreases accordingly; the feed speed increases or decreases simultaneously with the extrusion speed, because the volume of the screw material in the feed section remains unchanged , Only due to the increase or decrease of the speed, the melt pressure change.

Due to different fields and different types of twin screw extruder, they are widely used in many industries. To meet these growing demands, Nanjing JlEYA has committed to providing the increasing of twin screw extruder.

The extrusion system of a single screw extruder includes a screw, a cylinder, a funnel, a head, and a nozzle. The plastic is plasticized by the extrusion system into a uniform melt and is continuous under the resulting pressure through the screw of the extruder head.

What role does the heating and cooling system play in the single screw extruder?

The heating and cooling system of the inlet extruder consists of a heating device and a cooling device. It is a necessary condition for the smooth running of the extrusion process. The heater and cooling system shall ensure that the polymer material is melted and plasticized and that the temperature conditions during the molding process meet the process requirement.

The cooling system is generally installed in the cylinder, in the screw, and the bottom of the funnel of the inlet extruder. The cylinder cooling may be water-cooled or air-cooled. In general, small and medium extruder air cooling is used; Large series single screw extruders usually use water cooling or a combination of both. The main use of sludge cooling is a central water cooling system, the purpose of which is to increase the rate of solidification of the material, to stabilize the volume of discharges, and, at the same time, to improve product quality. The cooling system at the bottom of the funnel serves mainly to enhance the conveying effect of solids and to prevent the material particles from sticking due to the increase in temperature, blocking the material opening and impairing the supply. In general, in the case of extruders with screw diameters over 90 mm and fast-running screw extruders, a cooling device shall be installed at the bottom of the funnel.
