high quality Suction pipe 1. During the molding of rubber products, the cohesive force of the elastomer cannot be eliminated due to the large pressure pressing. During the molding and mold release, extremely unstable shrinkage (the shrinkage rate of rubber varies due to different rubber types) often occurs. It must take a period of time before it can be gentle and stable. Therefore, at the beginning of the design of a rubber product, no matter the formula or the mold, it is necessary to carefully calculate the matching. If not, it is easy to cause dimensional instability of the product, resulting in low product quality. 2. Rubber belongs to thermosetting elastomer, while plastic belongs to thermosetting elastomer. Due to different sulfide types, the temperature range of rubber molding and curing is quite different, even affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be properly adjusted at any time. If not, there may be differences in product quality. 3. The rubber product is the rubber mixture made from rubber raw materials after mixing in the internal mixer as the raw material. The formula is designed according to the characteristics of the required rubber products during mixing, and the required product hardness is determined. The product is molded by the rubber plate vulcanizer. After the product is formed, flash processing shall be carried out to make the product surface smooth without burrs. 4. The aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomenon that the performance and structure of rubber and products are changed due to the combined effect of internal and external factors in the process of processing, storage and use, thus losing their use value. Suction pipe Where can I find it? It is characterized by cracking, tackiness, hardening, softening, chalking, discoloration, mildew, etc. The following conditions shall be met when the ball mill uses the rubber lining plate: 1. The hardness of the ground material. The iron base alloy is similar to the rubber lining plate for materials below medium hardness, and the rubber lining plate is superior for materials above medium hardness. 2. The temperature of rubber lining plate is generally 70 ℃ - 90 ℃, and it can reach 110-130 ℃ under special circumstances. The temperature should be lower during dry grinding. 3. Feed size. Generally, the ball mill shall be more than 20-25mm; For the autogenous mill, the feeding particle size can be larger because no steel ball is added.

Suction pipe Where can I find it? It has become the standard configuration of the modern new ball mill, but many problems may occur during the use or installation of the rubber lining plate, which will cause the failure of the rubber lining plate of the ball mill. Here is a brief introduction to the causes of the more common failure of the rubber lining plate of the ball mill. The design and installation are not professional and reasonable. The design and installation are also common problems for many novice manufacturers. For example, the bolt holes for fixing the ball mill lining plate are square, which will cause stress concentration and fracture. Adjust the size of lining plate to control the gap between lining plates at about 8mm; The installation quality of lining plate is very important to the safe operation of ball mill. First, tighten the fixed wedge symmetrically, put the lining plate in sequence, and then use the tightening wedge to secure it; Therefore, professional installation guidance can easily avoid these problems. The reason why the rubber lining plate of the ball mill does not match the steel ball is relatively common, and it is easy for many novice manufacturers to ignore and make mistakes. During the operation of the ball mill, the rubber lining plate of the ball mill, materials and steel balls promote the normal grinding and crushing of the ball mill due to the interaction of forces. The hardness of materials is related to wear resistance, and the wear resistance increases with the increase of hardness, Tianjin Suction pipe It is a pair of friction pairs, and the increase of hardness of one side will cause the wear of the other side to increase. Therefore, the high wear-resistant rubber lining plate is matched with the high wear-resistant steel ball, and the low wear-resistant rubber lining plate is matched with the low wear-resistant steel ball, so as to ensure the normal wear of the rubber lining plate of the ball mill and extend the service life of the ball mill.

Tianjin Suction pipe It is one of the most common rubber products in life, used to transport various gases and liquids. Natural rubber, synthetic rubber and reclaimed rubber in rubber products can be used for the consumption of rubber sand blasting pipes. When reclaimed rubber is used to consume odorless rubber sand blasting pipe, care must be taken in selecting reclaimed rubber and formula design to meet the performance requirements of odorless rubber sand blasting pipe. When using recycled rubber to consume odorless rubber sand blasting hose, what problems should we pay attention to? The selection of reclaimed rubber for odorless rubber sandblasting hose is the basis for determining the quality of rubber, whether it is environmental protection rubber products or various odorless rubber products. When using reclaimed rubber to consume odorless hose, choosing odorless reclaimed rubber is the top priority. Application of odorless reclaimed latex, odorless reclaimed tire rubber, odorless reclaimed nitrile rubber and odorless reclaimed ethylene propylene rubber in reclaimed rubber products. The odorless butyl reclaimed rubber can be used for the consumption of odorless rubber sandblasting pipes. In addition, odorless hb isoprene reclaimed rubber can also be used for consumption of odorless rubber sandblasting pipes. In actual consumption, the raw materials of odorless isoprene reclaimed rubber (PP reclaimed rubber) are isoprene unvulcanized composite rubber and isoprene bottle stopper. They have strong viscosity, aging resistance and temperature resistance, and are ideal for odorless hose consumption to ensure quality and reduce costs. Pay attention to the vulcanization of odorless rubber sand blasting pipe. as everyone knows, Suction pipe Where can I find it? The design of vulcanization system of reclaimed rubber products directly affects the quality of rubber products, and the odorless rubber sand blasting pipe of reclaimed rubber is no exception. When using reclaimed rubber to consume odorless rubber sand blasting pipe products, vulcanizing agent, accelerator and other additives must be combined with odorless additives such as accelerator STT and accelerator D; When vulcanizing the rubber of odorless rubber sand blasting pipe, it is better to vulcanize at low temperature for a long time, which will cause full reaction to the rubber.
