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

Two, according to the classification of characteristics, according to various plastic physical and chemical characteristics, plastic can be divided into thermosetting plastic and hot plastic plastic two types. (1) thermoplastic plastics thermoplastics (Thermo plastics): refers to the heat will melt, can flow into a mold cooling after molding, and then heated and melted plastic; can be used for heating and cooling, which produces a reversible change (liquid vs. solid), is called a physical change. General purpose thermoplastic plastic, its continuous use temperature below 100 degrees Celsius, polyethylene, polyvinyl chloride, polypropylene, polystyrene and called the four major plastic. Thermoplastic plastics are divided into hydrocarbons, polar genes of vinyl, engineering, cellulose and other types. Become soft when heated, harden when cooled, soften and harden repeatedly, and maintain a definite shape. Soluble in a certain solvent; having a soluble property. Thermoplastic plastics with excellent electrical insulation, especially polytetrafluoroethylene (PTFE), polystyrene (PS), polyethylene (PE), polypropylene (PP) has a dielectric constant and very low dielectric loss dielectric, is suitable for high frequency and high voltage insulation materials. Thermoplastics are easy to shape, but they have low heat resistance and are easy to creep. The creep degree varies with the load, the temperature, the solvent and the humidity. In order to overcome the weakness of thermoplastics, meet the need of the application of space technology, new energy development and other fields, all the countries in the development of heat-resistant resin melt molding, such as polyetheretherketone (PEEK), polyethersulfone (PES), polysulfone (PASU) and polyphenylene sulfide (PPS) etc..

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:What brand is good blister machine?

Do you mean that the machine that has a blister machine has a brand? I don't know. I know what plastic material is made of.

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

Only with injection molding machines. Custom molds are required.

Q:PVC blow molding and rolling film difference

Blow molding: a method of forming a hollow product by expanding a hot melt parison closed in a mold by means of a gas pressure,

Q:Blister machine rules and matters needing attention

4, operators will be plastic packaging, paperboard, bakelite mold, counterclockwise rotation mode, the machine in debugging, automatic packing seal.5, the entire system and source are closed after the job is done.The above information comes from Nanyang machinery factory in Longgang District of Shenzhen city. I hope it can help you

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: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?

No matter what comes out, good finished products are good equipment

Q:The processing technology of PVC calendering film?

First of all, ST300 smooth powder to solve the PVC colored film industry generally exist ink adhesion, yellowing, transparency and other issues, such as advertising films, crystal films, sheets, packaging film, etc..
