Q:Doors and windows shock absorber seals, rubber blocks, rubber products, do not know where to buy, where suppliers?
If you buy less friends, you can go to the local building materials market decoration city to see, there will be.But if you buy more and want to find a manufacturer, I suggest you go to some of these forums to see if there is a suitable one.I have seen in Ali on a walk of rubber products, the products are Hebei Great Wall Co seal brand, is the first domestic production of spiral tube protection sleeve manufacturers, professional development, production and sales of rubber products such as rubber seal, seal, rubber protective sleeve
Q:How do you remove the black dirt on the rubber?
Apply toothpaste to the stain and brush it again and again as clean as newWith Senna water and kerosene on rubber and iron grinding interpolation results are goodThe black dirt on the rubber can also be removed by diluting it with alcohol
Q:What problems need to pay attention to when inflating the pipe?
Pipe water blocking airbag, closed water test, sewage pipe matters are different, big air sac, small sac also have differences, in terms of sewage pipes, we need to pay attention to the following points:1, because the airbag is rubber products, so afraid of scratching, when receiving airbags, we must first test gas test to see if there are broken places. Repair and replace in time.2, carefully check instructions, rated pressure, etc..3, in the ground to connect three pressure gauge, slowly filling some gas, slowly into the pipeline.4, clean up the pipeline wall, no burr, punctured balloon.5, carefully checking the pressure meter, slow inflation, do not look at the gas, to avoid pressure gauge not timely response and the consequences of explosive charge. When the work pressure is up, stop inflating and never exceed the pressure.6. The large air bag has a handle on it and prevents it from running.
Q:How to remove the rubber front?
At present, there are two kinds of machine trimming on the market: roller grinding and cold trimming at normal temperature. If the product added value is not high, not strong to Feng processing precision, recommended by the economic roller milling Xiu Feng, this is the products into the drum, small friction rub off Feng ball and rely on some products produced by each other. The advantage of this approach is that it is relatively economical.
Q:Does anyone know how to deal with the frosting of rubber and how to prevent it?
To reduce blooming, mainly by adjusting the formula to achieve, such as reducing the amount of antioxidant in summer, storage time is short before vulcanization, if you can consider the use of paraffin wax, microcrystalline wax, if sulfur spray frost can consider changing into insoluble sulfur. Because I don't know your recipe, I adjust it according to the actual situation.
Q:How can rubber be preserved without decay?
The sealing environment of rubber seals should be boring, which is also an important factor to avoid aging. In summary, the reserve environment for rubber seals is light, cool and boring.
Q:What are the causes of cracks in vulcanized rubber products?
Vulcanized rubber refers to vulcanized rubber, has the characteristics of constant viscosity, not easy to break, and rubber products are mostly made of this kind of rubber. Also known as "mature rubber", commonly known as rubber or rubber. Vulcanized rubber is a polymer compound, its monomers are CIS poly butadiene monomer -CH2-CH=CH=CH2- 1, 3- in the double bonds were open to the -S-S- curing agent, will connect the linear structure of polybutadiene rubber mesh structure.
Q:What are the applications of rubber airbags in the automotive field
Rubber accounts for 5% of the total weight of automotive materials, with an average of 100200 rubber parts per car, with a total number of 200500. Along with the automobile reliability, environmental protection and energy saving requirements continue to increase, and rubber materials, product structure optimization, improve the heat resistance, low temperature resistance, long aging, oil resistance, leakage resistance, long-term fatigue, and further reduce the cost has become the main topic of the development of automotive rubber. Fluorine rubber, silicone rubber, acrylic rubber and other special heat-resistant elastic body will still be the mainstream of the future direction of the development of automobile rubber.
Q:What's the difference between natural rubber and three yuan ethylene propylene rubber?
The electric property of natural rubber is a kind of non polar material, and it is a better insulating material. When the natural rubber vulcanization after the introduction of polarity factors, such as sulfur, accelerator, so that insulation performance.
Q:How to improve the hardness of rubber?
General 90SHA or more need to use hard resin or high styrene such things, of course, have to properly adjust the strengthening agent and curing system
