Rubber chemicals are dangerous goods, flammable and explosive. Such as curing agent, oil, carbon black, organic accelerator and antioxidant.
At the National Rubber Industry Information Conference which held in Chengdu, Sichuan Province, November 14-16, 2017,the rubber industry is most concerned about the prices of these two raw materials (rubber chemicals and carbon black)! To this end, the authoritative rubber additives industry also analyzed the price of additives and predict: ● The main reason for price increases this year First,
Common high-temperature cable will be wrapped with a layer of “rubber protective layer”, when such a protective layer is damaged, the high-temperature cable inside will be damaged, so can not continue to use, so manufacturers will peripheral rubber protective layer anti-aging Processing, this process involves the antioxidant. The first point: Because of the different characteristics of each antioxidant, and different
Wire and cable will be subject to heat, oxygen, mechanical stress, light, high energy radiation and other factors in the usage, gradually aging, resulting in reduced product insulation properties. In order to extend the service life of wire and cable, cable manufacturers often use rubber antioxidant, but the protective effect of each antioxidant have limitations, and wire and cable and
The analysis of rubber chemicals in rubber products has important practical significance.As the rubber products added more types of additives, large differences in the amount of addition, part of the assists have reacts, so the full analysis of rubber additives is a There is a higher degree of difficulty.Through medium pressure chromatography, infrared spectroscopy qualitative method, identification of ethylene-propylene rubber
It is reported that car tires contain about 30% of carbon black, and this part of the carbon black is processed to increase the use of rubber for the durability. Carbon black is a product of carbon and other carbonaceous materials that are not completely burned or thermally decomposed under conditions of insufficient air, which means that it is not
On October 18th, the new party congress was opened at the Great Hall of the People in Beijing. Before the meeting, the press spokesman for the conference briefed the media on the preparation of the meeting and the questions and answered questions. When talking about “one belt,one road”, the spokesman said that the “one belt,one road” initiative has always adhered
In the production of rubber products, the use of calendering machine or extruder preformed in a variety of shapes, different sizes of the process, called the molding. Forming methods are: Rolling is suitable for the manufacture of simple sheet, plate products. It is the compound by pressing the press pressed into a certain shape, a certain size of the film
With working and development of the rubber aging process, rubber and its products will gradually reduce the performance or complete loss its value. In order to extend the service life of rubber products, it is necessary in the rubber with some of the material can inhibit the aging process, thereby extending the rubber and its products storage period and service
With the development of society, the use of dispersants has also been more and more attention. The effect of the dispersant is to reduce the time and energy required to complete the dispersion process using a wetting and dispersing agent, to stabilize the dispersed pigment dispersion, to modify the surface properties of the pigment particles, and to adjust the movement
