What's the difference between silicone products and rubber products?
Physical properties are different: nitrile rubber products waterproof, weak acid, weak base, anti oil, etc., silicone rubber waterproof, environmentally friendly, non-toxic, good elasticity, appearance, color and appearance.
How does the rubber part of the watch become yellow?
The rubber strap is yellow and rubbed with the weld polish. Remember, the ratio is 1 to 70.
What are the bridge rubber air bags used for?
The bridge is a kind of rubber bladder contraction, inflatable rubber bag, Yongsheng bridge hollow board internal mold is used to form the mold cavity concrete, prestressed concrete hollow slab in the mold is simple to use, safe and sanitary, simple operation, time saving, labor saving. The rubber gasbag is inflated for use, easy to use and convenient to remove after use, saves labor time and labor cost, and reduces work intensity.
What are the uses of ethylene propylene rubber?
In the electrical and electronic industries, the main use of ethylene propylene rubber excellent electrical insulation, weather resistance and corrosion resistance, in many electrical components used in this kind of rubber. For example, the production of cables with ethylene propylene rubber, especially submarine cables, is replaced by EPDM or EPDM/PP instead of PVC/NBR. The insulation performance and service life of cables have been greatly improved. In the transformer insulation pad, electronic insulation sheath is also a large number of ethylene propylene rubber production.Ethylene propylene rubber combined with other rubber is also a great field of ethylene propylene rubber applications. EPDM can be used in conjunction with other rubbers to improve performance and reduce costs. But due to various complex agents on the affinity of different polymers, covulcanization depends on the polymer crosslinking efficiency of different polymers and may not reach the molecular level compatible blend, but there were no phase separation system. The unequal distribution of complexing agents has a major impact on the properties of ethylene propylene and rubber.
Rubber rolling process for making rubber products
Calendering equipment: calender, calender, by roller, frame and bearings, pitch device, roller deflection compensation device, as well asAuxiliary pipe device, motor drive mechanism and thickness detection device and other components.
What's wrong with rubber whitening?
Rubber whitening (spray cream) the main reason for analysis, rubber spray cream, including rubber surface spray and surface spray cream. Spray (Bloom) is a phenomenon in which liquid or solid agents migrate from rubber to rubber surfaces [1]. It can be seen that the inner compound of rubber will precipitate and form a spray. There are three kinds of forms of rubber spray. Powder spraying, wax injection, injection (also known as exudation).1. powder is a curing agent, accelerator, activator, antioxidant and filler powder with precipitation agent on the rubber surface, and form a layer of powder.2. spray wax is paraffin wax, ceresin wax precipitation etc. on the rubber surface, forming a layer of wax.3. fuel injection is softening agent, tackifier, lubricants, plasticizers and other additives in liquid precipitation of the rubber surface, and form a layer of oil.In practice, frost forms on rubber surfaces sometimes appear in one form, sometimes in two or three forms.
How to solve the exhaust problem in rubber vulcanization process
It is mainly divided into two kinds of natural rubber and synthetic rubber. Natural rubber is made from rubber, rubber and grass. Synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all fields of life. It has a wide range of uses. [1] can also be divided into rubber with natural rubber, general rubber, styrene butadiene rubber, nitrile rubber, silicone rubber, butadiene rubber, butyl rubber, EPDM rubber, chloroprene rubber types.
