Rubber Parts Knowledge

I. Rubber properties The most important feature of rubber is first of all the very small modulus of elasticity and the high elongation. Secondly, it has quite good resistance to air permeability and various chemical media and electrical insulation properties. Some special synthetic rubbers have good oil and temperature resistance and can resist the swelling of fatty oils, lubricating oils, hydraulic oils, fuel oils and solvent oils; cold resistance can be as low as -60°C to -80°C and heat resistance can be as high as +180°C to +350°C.

Knowledge of rubber parts and their classification

Rubber parts are products made of rubber. Rubber has good flexibility, sealing and insulating properties, and is widely used in many industries, and it is naturally used in cars as "steel and iron".

Acrylic resin adhesive (ACM), our code (A)

Advantages: both good heat and oil resistance performance, stable performance in lubricants containing sulfur, phosphorus and chlorine additives. It is also resistant to aging, oxygen and ozone, ultraviolet light, and has excellent airtightness. Use temperature range: about -25～+150℃. Disadvantages: poor cold resistance, not resistant to water, not resistant to steam and organic and inorganic acids and alkalis. It swells severely within water-soluble solutions such as methanol, ethylene glycol and ketone ester. Also poor elasticity and wear resistance, poor electrical insulation and poor processing performance.

Ethylene propylene rubber (EPDM), the factory code is (E)

Advantages: very good aging resistance, weathering resistance, better electrical insulation, better impact elasticity, oil resistance. Disadvantages: slow vulcanization speed, self-adhesive performance, poor hot tear performance, bad processing performance. Uses: Manufacture of heat-resistant transport belts, steam hoses, chemical-resistant seals, shock-absorbing pads and waterproof materials and automotive leather bowls, leather rings, etc.

Introduction to rubber basics and general knowledge of various gums

1. Rubber: It is an organic polymeric elastic compound with: (1) long-chain polymers (molecular weight in the tens to hundreds of thousands or more) (2) lively movement of the links of the molecular chain. (3) easy rotation and curling between the links of the molecular chain. (4) The intermolecular forces are small. (5) It is amorphous at room temperature. (6) The molecules can be cross-linked and have the necessary properties before and after cross-linking.

How to choose the right equipment according to the characteristics of the conveyor

It is a kind of conveyor which can be used horizontally and also at a certain inclination angle. There are two types of conveyors, fixed type and mobile type, of which the mobile type can adjust the working position and conveying height, while the fixed type is fixed and cannot be moved. Screw conveyor, which is also one of them, is mainly used for conveying, elevating machine loading and unloading bulk solid materials, and its main advantages are simple structure and low cost.

Ltd. Flame retardant V-belt Introduction

I. Use occasions and characteristics of flame retardant V-belt: Flame retardant V-belt is mainly used in coal mines, petroleum, underground, natural gas and other occasions that need flame retardant and anti-static. It is characterized by high transmission efficiency, high temperature resistance, flex resistance, high strength, smooth transmission, etc.

The process of screw conveyor should be qualitative

If we do not have strict requirements for the manufacturing process of the products, it is difficult to have good products. Of course, for general products, the process can also help us to get good savings in terms of efficiency and cost.

Use of belt conveyor

Belt conveyor, as a very wide range of conveying equipment, can be seen in almost all industries. Belt conveyor can transport a variety of materials, large transport capacity, stable performance, long continuous working time, etc. It can work as a single conveyor according to the customer's conveying process requirements; it can also transport materials over long distances in a rugged and complex environment, realizing automatic and integrated production operations; it has been widely used in mining, coal, electric power and other fields, becoming the ideal equipment for long distance, large capacity and continuous transportation. equipment. For the use of the belt conveyor process, it must be carried out in accordance with the relevant operating specifications. Today we will talk about the use of belt conveyor precautions.

A production method of automatic cloth wrapping device for V-belt production

V-belt, or V-shaped tape, is a unique kind of conveyor belt, which is a kind of mechanical equipment used to transmit force and transport items. Its advantages of easy installation, small footprint, high transmission efficiency and low noise are widely used. Cladding operation is an important process in the production of rubber V-belt. The existing V-belt wrapping work is usually manual wrapping, which is time-consuming, labor-intensive, inefficient and ineffective. For this reason, we propose an automatic wrapping device for V-belt production.
