Q:Is polyurethane and polyurethane rubber one thing?: Plastics, such as Taiwan and Hongkong, are commonly referred to as plastics, so there is little point in distinguishing between plastics and rubber. From a theoretical point of view, the distinction between plastic and rubber is generally based on whether the glass transition temperature (Tg) of the material is above normal or below normal. Polymers that are generally less than Tg at normal temperature are called plastics (e.g., polyethylene, Tg, -78 degrees), while polymers with Tg temperatures higher than normal are called rubber.

Q:Does anyone know how to deal with the frosting of rubber and how to prevent it?: The reason: if the formula is in before the precipitation of sulfide precipitation may be white, Zinc Oxide or stearic acid, yellow sulfur may be, after curing products, may be white wax, light green or other color may be. The weather is hot, after curing the product easy to spray cream, can properly reduce the antioxidant.

Q:Why should the tire be made of rubber?: The molecular chain of rubber can be crosslinked, and the crosslinked rubber can recover quickly when it is deformed by external force, and has good physical and mechanical properties and chemical stability. It is widely used in the manufacture of tires, hoses, tapes, cables and other rubber products.

Q:How can rubber products prevent fading?: Light and white rubber products are prone to yellowing in the course of use and storage, thus affecting appearance and quality, resulting in various economic disputes and irreversible losses.

Q:How are rubber wires processed?: In the production of rubber products, vulcanization is the last process.Vulcanization is a crosslinking process in which rubber molecules change from linear structure to network structure under certain conditions. Curing methods are cold vulcanization, room temperature vulcanization and heat vulcanizing three kinds. Most rubber products are vulcanized by heat. Hot vulcanizing equipment, vulcanizing pot, flat vulcanizing machine, etc.. Rubber wires and cables are vulcanized by continuous hot air.

Q:Rubber Mooney value is what meaning, what is the role of: Mooney viscosity (Mooney viscosity) also called rotation (Mooney) is determined by numerical viscosity, Mooney viscometer, synthetic rubber can basically reflect the degree of polymerization and molecular weight. The rotor is a standard Mooney viscometer, at a constant speed (2 RPM), rotating in a closed chamber in the sample the viscosity change of shear resistance. The size of the sample and the rotation of the rotor during the curing process, through the force measuring device is displayed on the dial to Mooney units, at the same time interval can be read Mooney, vulcanization curve, door number rose after the first drop, 5 unit increase in the time from the lowest point called the Mooney scorch time, the Mooney scorch and then increased to 30 units and the time that scorch time.

Q:How to test the abrasion resistance of rubber?: Rubber: the word "rubber" comes from the Indian language "cau-uchu", meaning "weeping tree"". Natural rubber is flowing out from the Hevea latex when tapping after solidification and drying process. The finished product is material with elasticity, insulation, waterproof and air.

Q:The difference between plastic rubbers and rubber boots.: There are the following differences:1, material is different, the former is plastic, and the latter is rubber;2, comfort is different, the former is relatively hard, uncomfortable wearing, and the latter is relatively soft.3, rubber shoes need good maintenance, and the former is not necessary.

Q:Process for producing rubber products: Rubber elastic, lack of necessary processing plasticity properties, therefore not easy to process. In order to improve the plasticity, so the rubber mastication, so the mixing of ingredients easily dispersed in rubber, which also helps to improve the permeability of the fabric into rubber and molding in rolling and molding process. The long chain molecular degradation were called plasticity forming process of mastication. Mechanical plastication and mixing two kinds of thermoplastic plastic mixing method of rubber. Mechanical plasticization is the reduction of long chain rubber molecules at shorter temperatures through the mechanical extrusion and friction of the extruder, which changes from a high elastic state to a ductile state. Hot hot mastication is to pass into the rubber in the compressed air in the heat and oxygen under the effect of the degradation of long chain molecules to obtain shorter plasticity.

Q:How can I get rid of the rubber?: One way is to use rubber deodorant is a kind of used to remove or reduce the acid degradation, all kinds of rubber produced in the processing or in the process of the use of alkoxy compounds, aldehydes, vinyl compounds, ammonia, CO2 plastic smell of chemical additives, the smell if inhaled for a long time will stimulate the senses give a person, discomfort or even harmful to the body, have two times of pollution to the environment, the chemical composition of different varieties of rubber and odor molecules are different, and in the actual development of Chinese ocean chemistry and etc. Ma'anshan Keli chemical is used in chemical chelation is also used, is the other mechanism, in addition to taste rubber both the rubber agent itself, also want to consider a variety of additives such as odor curing agents released, in addition to the use of rubber ingredients to improve rubber products and improve the level of environmental protection, rubber The production environment is of great help to the comprehensive utilization of regenerated rubber resources. A form of powder or liquid used in rubber, usually based on odor and odor characteristics
