Q:How can I remove the rubber flavor on rubber products? It smells terrible
This odor is stubborn, more difficult to solve in a short timeThe peculiar smell of a small rubber component in my car used for a week before cleaning it. If the price is not high, I suggest you change it.
Q:Bought a mouse pad, a little rubber, how to remove?
The best way is to put the balcony outside, let it go to taste naturally, generally a few days can be, do not expose to the sun, we are all solved like this.The mouse pad more or less have to taste, taste the most common cloth pad, because the part is in addition to cloth rubber, relatively the rubber is not very high, even as the high-end gaming mouse pad will have a pungent taste, which is unable to avoid, but really I don't smell in use also, not in the mood to smell, unless you put the nose close to become obvious.It is best not to wash casually or rub some potions, this will only backfire, and occasionally wash the mouse pad, you can, because the wash will be more degumming.
Q:How to identify the tire rubber is raw or cooked
Rubber molding, after pressing, the elastic body is within the cohesion can not be eliminated, the molding die, often have a very unstable contraction (rubber shrinkage due to rubber vary), required after a period of time, and can be stable. Therefore, when a rubber product design at the beginning, regardless of formula or mold, it is necessary to carefully calculate the coordination, if not, it is easy to produce product size instability, resulting in lower quality products.
Q:What are the causes of chapped rubber products?
Measures to prevent aging:From the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging
Q:How to make white rubber products do not yellow or delay yellowing time?
The process of yellowing resistance is very complicated and involves many aspects, but the prevention of a certain point is not up to standard.Yellow change is mainly formed by aging. Controlling yellowing is the process of controlling aging.
Q:What is the size of the scorch time of the rubber?
The scorch time is often measured by scorch time. The longer the scorch time is, the less likely it is to occur early vulcanization. The shorter scorch time is, the more likely the early vulcanization occurs during the processing. The scorch time can usually be Mooney viscosity meter to determine.
Q:What is the rubber composition of sole?
Styrene butadiene rubber (styrene butadiene rubber) is a kind of macromolecule elastomer material synthesized by copolymerization of butadiene and styrene as main monomers. Its quality is even and pure, and impurities are mixed little. It can be dissolved in benzene, toluene, gasoline, chloroform and other organic solvents. The unsaturated double bond in the styrene butadiene rubber molecule and the vulcanizing agent form a cross-linked network structure by substitution or addition reaction, and the styrene butadiene rubber vulcanizate reinforced by the reinforcing agent has higher physical and mechanical properties.Styrene butadiene rubber vulcanization rate is slow, but vulcanization flatness is good, not easy to over vulcanization, with aging resistance, heat resistance, wear resistance, and other excellent performance.
Q:What is the difference between vulcanized rubber and butyl rubber?
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.
Q:EPDM rubber foam?
Three yuan ethylene propylene diene rubber (EPDM) is used as matrix, and azo two, AC and HOBSH are used as foaming agents, in order to systematically and quantitatively study the preparation process of EPDM foam material and the relationship between structure and properties of foamed material. At present, most of EPDM rubber foam material with low reinforcing carbon black filler, fine particles of carbon black can avoid the difficult problem of dispersion and high viscosity, but now the industry of light colored rubber products demand more and more, so this paper using silica as reinforcing filler rubber, studied the preparation process of EPDM foam rubber and the effects of molding conditions on the foaming process. Subsequently, the change of accelerator, filler, foaming agent and the amount of paraffin oil was analyzed. The curing properties, mechanical properties and SEM analysis were carried out, and the influence of various factors on the structure and properties of foamed material was discussed. The influence law of each formula factor on foaming is summarized, and the optimum formula dosage is expected to be found. Finally, we also through the compression behavior of stress-strain curves of EPDM rubber foam materials with different density, the energy absorption efficiency of E and I analysis of the ideal parameters of EPDM foam energy absorption characteristic of absorbing ability of W and.
Q:What does rubber mean?
Rubber is derived from latex of rubber trees, rubber plants, etc. it is made of elastic, insulating, impermeable and air.
