Q:How are rubber and plastic calender classified? What are the features and uses?

The composites with their matrix resin have higher mechanical properties and chemical resistance, heat forming and welding, and the interlaminar shear strength is better than that of epoxy resin. Such as PEEK as matrix resin and carbon fiber composite material, fatigue resistance exceeds epoxy / carbon fiber. The utility model has the advantages of good impact resistance, good creep resistance, good processability, continuous use at 240~270 DEG C at room temperature, and is a very ideal heat-resistant insulating material. Using polyethersulfone as composite material matrix resin and carbon fiber with high strength and hardness at 200 DEG C, in -100 C can still maintain a good impact resistance; non-toxic, non flammable, smoke at least, radiation resistance, expected key parts of it can be used to make the space shuttle, also can be molded into radome. Formaldehyde crosslinked plastics include phenolic plastics and amino plastics (such as urea formaldehyde melamine formaldehyde etc.). Other crosslinked plastics include unsaturated polyester, epoxy resin, phthalic two, diallyl resin, etc.. (2) thermosetting plastics are plastics that can be cured or insoluble under heat or other conditions, such as phenolic plastics, epoxy plastics, etc.. Thermosetting plastics can be divided into two types: formaldehyde, cross-linking and other cross-linking. After the hot processing, a non melting curing substance is formed, and the resin molecule is cross-linked into a network structure by a linear structure. Further heat will break down

Q:For example, three roller calender, the size of the three roller models are the same, or is there a big difference?

Are the same, that is, there is a spindle, two transmission shaft, 3 roller diameter is 18 inches

Q:Is the roller mill in the plastics industry a special type of work?

Type of work: toxic and harmfulWorking conditions: use three roller and four roller calender to make the plasticized material pass through calendering, injection molding, blow molding and extrusion processing into various plastic products.

Q:What is the difference between injection molding machine and plastic suction machine?

Only with injection molding machines. Custom molds are required.

Q:What does blister machine do?

Plastic machine is mainly divided into two categories, one is used for production of billboards, a film for sliding door

Q:What what plastic products should use "rolling, extrusion, blow molding, pressing, plastic, rotational molding and injection"?

Calendering, extrusion, blow molding, pressing, plastic, plastic and plastic injection, use the following:1, extrusion molding, the use of: extrusion method is mainly used for thermoplastic molding, can also be used for certain thermosetting plastics.Such as tubes, rods, wires, plates, films, wires, cables, cladding, etc..2, rolling molding, the use of: Ting used for films, sheets, artificial leather and other coating products.3, blow molding, the use of: mainly used in a variety of packaging containers and pipe film manufacturing. All the melt index was 0.04 ~ 1.12 are excellent materials of hollow blow molding, such as polyethylene, polypropylene, PVC, polystyrene, thermoplastic polyester, polycarbonate, polyamide, polyacetal resin and cellulose acetate, which is used widely in polyethylene.

Q:Which manufacturer does calendering machine do better? Be anxious?

What do you look at the main rolling mill production process, what is the Suzhou dongfulai, doing good, they are mainly based on the customization process

Q:Characteristic parameters of calender

2. Power calculation:Power consumption is also an important parameter in the design of calender, and it is difficult to obtain it accurately by theoretical formula. Several empirical formulas are briefly described here, which are approximately calculated:1) the power calculation of a single motor driveA, according to roller linear speed calculationN, =a, L, VFormula a -- Calculation factorL - roller work part lengthV - calendering speedB. is calculated by the number of rollersN=K, L, nFormula K -- Calculation factorL - roller work part lengthN - number of rollers.The common disadvantage of the above two methods is that they do not consider the nature of the processed rubber material and the processing method, and the influence of the roller diameter on the power, and their influence on the power consumption is very large. It can be seen that the above two formulas are one-sided.C. analog computingBy using the known machine characteristics and power consumption, the calculation coefficients a and K are calculated, and the power of the calender is designed by using the upper model.2) the power calculation of multiple motors in transmissionBecause each roller has different positions and process uses, the speed of the rolling line is different, and the power consumed by each roller is different in the process of rolling. Under normal conditions, the feed roller consumes much more power than the roll.A, when rolling, the power consumption of two rollers is proportional to the roller linear speedIf the linear speed of two rollers is V1, V2, and the power is N1 and N2, respectively:N1/N2==V1/V2The power consumed by B and glue is only 6% of the total powerN =0.06N total NN sticking - rubber roller power,N total effective total power,ETA - total transmission efficiency.According to the above two points, you can calculate the power of each roller.

Q:I want to buy a new fully automatic blister machine. I wonder if that made brand is good What's the price? How many pieces can be produced in a day with a 1000*450 thick plastic suction disk?

Do not know what brand of blister machine you use, the brand is not the same, the price is not the same, the price according to the brand and whether it is made in China is very different. In the ten major brand network MAIGOO, the ten major brands can refer to, I think the above brand is still very complete!

Q:The processing technology of PVC calendering film?

Characterized by high yield and good quality. But the process equipment is complex, and the investment is large. Soft rolled film thickness generally below 0.25mm, formulations plasticizer content greater than 25phr. PVC calendered film occupies an important position in the plastic film, the cover, Yantian industrial packaging, electrical insulation, pneumatic products, advertising light boxes, waterproofing, commodity packaging, etc. have a wide range of applications.
