The global automobile industry has been steadily launched, driving the consumption of rubber chemicals. The output of China’s rubber chemicals accounts for more than 70% of the world’s total, environmental protection tightens, supply is shortened, and prices rise substantially in 2017, and it is estimated that it will be stable in 2018. Let’s take a closer look at the results
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
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 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
Came into August, a titanium dioxide dragon has twice lowered product prices. It is understood that the pre-price of the enterprise is always higher than the market price, after the price adjustment, the price and the market gradually closer to the average price. After the completion of the price reduction, the enterprise take the goods stable, the product inventory pressure
Although rubber additives have many types, but the added ways are mostly the same, and there are two main ways: One is the impact of dosing: the general is to reverse osmosis pressure to 0.3Mpa below, the use of drugs should be completed in 2-4 hours. The reason why this will be used, mainly due to the surface of the
The main raw materials of rubber products are raw rubber, various compounding agents, as well as fiber and metal materials as skeleton materials. The basic production process of rubber products includes plasticizing, kneading, rolling, pressing, forming and vulcanizing six basic processes. The process of rubber processing is mainly to solve the plastic and elastic contradictions in the process, through a
Carbon black is a material which can spontaneous combustion easily, when the ambient temperature reaches a critical ignition point will occur spontaneous combustion. In the carbon black production process, the external air into the carbon black collection or air supply system, can ignite the flammable exhaust or even explosion. At the beginning, there will be some water and volatile gas
