Butyl rubber is synthesized from petrochemicals and is a copolymer of isobutylene and a small amount of isoprene. Subsequent halogenation produces halogenated butyl rubber—usually bromobutyl or chlorobutyl. What is bromobutyl rubber? Bromobutyl rubber: is a terpolymer of isobutylene, isoprene, and brominated isoprene. Bromobutyl rubber   (BIIR) is an isobutylene-isoprene copolymer elastomer containing reactive bromine. Because bromobutyl rubber has a substantially saturated backbone of butyl rubber, it has many performance characteristics of butyl polymers, such as higher physical strength, better vibration damping properties, low permeability, aging resistance and Weather-resistant. The invention and use of the halobutyl rubber innerliner has in many ways enabled the modern radial tire. The use of these polymers in tire innerliner compounds can improve pressure holding properties, improve the adhesion between the innerliner and the carcass, and improve tire durability. Advantage: ...

  Each medicinal glass bottle is annealed, the role of annealing is to eliminate or reduce the thermal stress of the glass bottle to the allowable value of the heat treatment process, after annealing, it is not easy to rest in extreme cold and heat. Annealing of glass bottles is to eliminate and reduce the stress. Glass bottles undergo drastic and uneven temperature changes during the manufacturing process, which leads to thermal stresses in the glass product. This thermal stress can reduce the strength and thermal stability of the glass bottle, and even lead to self-cracking of the glass bottle.     Pharmaceutical glass bottles  Stress in glass is generally divided into three categories, namely thermal stress, mechanical stress and structural stress.   1. thermal stress: glass products due to temperature differences in the stress called thermal stress, according to its existence can be divided into temporary stress and permanent stress. (1) temporary stress: th...

In slurry pumps, the impeller and the inside of the pump casing are always exposed to the slurry and must therefore be protected against wear accordingly. "The choice of material for the impeller and pump casing is as important as the choice of the pump itself!"     Three different conditions that generate wear in slurry pumps. Abrasion, erosion, corrosion 1.Wear Wear is divided into three main types. In slurry pumps, we have mainly abrasion and low stress wear. The rate of wear depends on particle size and hardness. Wear in  slurry pumps  occurs in only two areas. a. Between the impeller and the fixed inlet. b. Between the shaft sleeve and the fixed packing. 2. Erosion This is the main wear of the slurry pump. The reason is that the particles in the slurry hit the material surface at different angles. The way the pump is operated can seriously affect erosion wear. In general, erosion wear is lowest at BEP flow rates and increases as the flow rate increases and decre...
