1. Production process At room temperature, add the rubber mixture to the internal mixer for internal mixing. The internal temperature of the internal mixer was 65-75°C. After a period of internal stirring, the base rubber is obtained. At this point, the accelerators and auxiliary materials are added, followed by internal mixing for 5-10 minutes. After unloading, adjust the roll distance
1. Domestic production status of rubber additives In the past 10 years, my country’s rubber additives have developed rapidly, and the degree of intensification of enterprises and product concentration has increased significantly. Affected by multiple factors such as industrial structure adjustment, safety and environmental protection, some rubber additives enterprises showing a shrinking trend. In recent years, the production capacity and
Hainan Rubber: In 2021, the company will produce 102,000 tons of rubber products. The company’s main preliminary processing products include full latex rubber chemicals, concentrated latex, No. 20 standard rubber, etc., of which full latex rubber and No. 20 standard rubber are delivery certified by Shanghai Futures Exchange. target. This week, the operating rate of tire companies in Shandong increased
Adsorbed on the surface of the solid particles, making the surfaceof agglomerated solid particles easy to wet. The polymer dispersant on the surface of the solid particles forming the adsorption layer, the surface of the solid particles of the charge is increased to improve the particle formation reaction between the steric hindrance. The solid particles are formed on the surface
For those who are not engaged in the chemical industry, many aspects of chemistry may be unknown to us. If we do not understand rubber additives and polymers, then we will not know the relationship between them. Rubber auxiliaries play an important role in the development of industry. In order to improve the quality of manufactured products, many issues must
The dispersion properties of carbon black have a great influence on carbon black and products. Usually, the three-roll mill grinds carbon black for dispersion. Commonly used dispersion media are glass beads, steel beads, and ceramic beads. The working principle of the three-roll mill grinding carbon black is to disperse and pulverize the carbon black by the shearing force and pressure
This project intends to replace the ammonia water with the self-developed and patented nano-preservation technology formula in the rubber milk processing process, so as to fundamentally solve the harm of harmful substances in natural rubber and ammonia nitrogen (high nitrogen wastewater) to the water source environment. Pollution. At present, all of the world’s natural rubber milk preservation uses ammonia water,
Pre-dispersion of rubber additives has been proposed in the 1940s. Industrial production began in the 1980s, and large-scale industrial production began in the mid-1990s. After 2003, it was gradually recognized by everyone. At that time, there were only a few foreign-owned factories in the country. After 2008, domestic factories started to start and gradually increased. 1. Why is the pre-dispersion
Ultrafine titanium dioxide is one over ten of the common titanium white pigment particle size.This small size gives the product a lot of special properties, such as ultraviolet shielding performance, color is rich in effect, stress dispersion, appear in the film “transparent”, etc.These unique properties of highly unified, make its in sunscreens, fast plastics, coating protection and other special field
1.Defoaming and strong, with less does not affect the basic nature of the bubbling system. 2.Diffusion, permeability, energy and oil, cutting fluids fully compatible. 3.Good heat resistance, chemical stability, non-corrosive, non-toxic, no adverse side effects, non-flammable, non-explosive. 4.Acids, alkalis, salts, electrolytes and hard water can be used. 5.Its performance can be comparable with the imported products, while the price of
