Q:What are the reasons for rubber cracking after shock absorption of rubber products?

Shock absorber rubber suspension products, durable rubber cracking:1, rubber aging, weathering, heat resistance;

Q:How long is the warranty period for EPDM?

Rubber product (rubber products) refers to the natural and synthetic rubber as raw material to produce all kinds of rubber products activities, including the use of waste rubber reproduction of rubber products.

Q:What's the difference between silicone rubber and 703.704 glue?

703, temperature range of -50-150, water resistance, salt water effect is good, mainly used for cable potting, instrument waterproof seal, watchcase bonding;

Q:What is the cause of the bursting of rubber products and how should they be improved?

There are five reasons for the bursting of rubber products: 1. forming temperature is too high, or the temperature of the upper and lower template is inconsistent. 2. the exhaust line is too open or exhaust time is too late. 3., the material quickly cooked. 4., the mold structure is irrational, there is no running trough. 5., down weight, overweight.

Q:What kind of product is suitable for rubber trimmer? Where's the rubber trimmer?

Generally used for metal strip trimming, that is, after the strip of metal strips with a fixed tool to remove burr or chamfer on both sides of the required radian,Scope of application: used in tableware, stationery, hardware, sheet metal and other special equipment industry.Main functions: grinding and polishing of double sides of roll beltApplicable materials: stainless steel, copper strip, aluminum belt and other metal coil.It has the advantages of rough grinding, fine grinding and polishing. It is suitable for grinding the bevel and straight edges of metal belts of different sizes and thicknesses, and is equipped with grinding wheels and spare grinding wheels. The grinding wheel has the advantages of long service life, regular forming rules and high efficiency.

Q:What's rubber skin?

The general rubber has good comprehensive properties and is widely used. The main contents are as follows: natural rubber. From the latex of the Hevea tree, the basic chemical composition is cis polyisoprene. Good elasticity, high strength and good comprehensive performance. Isoprene rubber. The full name is cis -1, 4- polyisoprene rubber, a high CIS synthetic rubber made from isoprene, because of its structure and properties similar to natural rubber, it is also called synthetic natural rubber. Styrene butadiene rubber. Referred to as SBR, made by copolymerization of butadiene and styrene. According to the production method, emulsion polymerization, styrene butadiene rubber and solution polymerized styrene butadiene rubber are divided into emulsion polymerization. Its comprehensive properties and chemical stability are good. The br. The full name is cis -1, 4- polybutadiene rubber, referred to as BR, made from butadiene polymerization. And the other than universal rubber, vulcanized butadiene rubber cold resistance, abrasion resistance and excellent elasticity, dynamic load, less heat, good aging resistance, easy and natural rubber, chloroprene rubber, nitrile rubber and etc..

Q: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.

Q:The silica gel of the kettle is the white one that is waterproof and leaked out

Natural rubber (NR) is mainly composed of rubber hydrocarbons (polyisoprene), containing a small amount of protein, water, resin acids, sugars and inorganic salts. The utility model has the advantages of large elasticity, high extension strength, high tear resistance and electrical insulation, good abrasion resistance and drought resistance, good processability, easy adhesion to other materials, and superior performance in synthetic rubber in comprehensive performance. The disadvantage is that oxygen and ozone resistance is poor, easy aging, metamorphism, oil and solvent resistance is bad, resistance to acid and base corrosion is low; heat resistance is not high. Temperature range: about 60 DEG C 80. Make tires, rubber shoes, hose, tape, wire and cable insulation and sheath, and other general products. The utility model is especially suitable for making torsional vibration eliminator, engine shock absorber, machine support, rubber metal suspension element, diaphragm and molded product.

Q:What solvent is used to clear the melted rubber layer?

Natural rubber is made from latex, and a portion of the non - rubber contained in the latex is left in the solid rubber. In general natural rubber contains rubber hydrocarbon 92%-95%, but not rubber hydrocarbon accounts for 5%-8%. Because of the different processing methods, different habitats and even different seasons, the proportion of these ingredients may vary, but basically within the scope.Proteins can promote the vulcanization of rubber and retard aging. On the other hand, the protein has strong water absorption, can cause rubber moisture absorption, mildew, insulation degradation, protein and increase heat generation shortcomings.

Q:What kind of material does the shockproof rubber cushion usually choose? What's the hardness?

Of course is to choose butadiene rubberThe biggest characteristic is the molecular structure, mainly for the CIS structure, so the elasticity, cracking resistance and dynamic performance is excellent, and the rubber pad shock proof function is guaranteed, and the rubber cushion life is guaranteed, and the hardness is about 55.
