wear-resisting 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 Price 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 Price The following recommendations contain a series of precautions to prevent items from aging to a greater extent during storage. 1. During storage, the rotating plan system shall be adopted to shorten the storage time of high-pressure braided hose as much as possible. If long-term storage cannot be avoided and the following recommendations cannot be followed, high-pressure braided hoses should be thoroughly inspected before use. 2. Physical storage conditions: The high-pressure braided hose must be stored without mechanical pressure, including excessive stretching, compression or deformation, and without contact with sharp or sharp objects. High pressure braided hoses should be stored on suitable supports or on dry ground. High pressure braided rubber tubes packaged as coils must be stored horizontally. High pressure braided rubber pipes shall not be stacked. If stacking cannot be avoided, the stacking height shall not cause permanent deformation of the high-pressure braided rubber pipe below. Pumping high-pressure hydraulic hose is a common high-pressure hydraulic hose. In order to ensure the operation safety of the pumped high-pressure hydraulic hose, the following small series will briefly introduce the correct use of the pumped high-pressure hydraulic hose: 1. Before each use of the high-pressure hydraulic hose, the surface of the high-pressure hydraulic hose must be evenly coated with soap liquid, which can play a non bonding role between the high-pressure hydraulic hose and the concrete, and play a lubricating role in the drawing process, It can greatly increase the reuse times of high-pressure hydraulic hoses. 2. Installation: first, insert the steel hinge wire into the inner hole of the draw tube to avoid extrusion deformation when pouring concrete. Then, pull out the high-pressure hydraulic hose coated with soap liquid from the prestressed hole and fix it in the correct position with a fixing ring. The spacing of the retaining rings is controlled by the suspension and is usually about 500 mm. wear-resisting Suction pipe When connecting the high-pressure hydraulic hose, wrap both ends of the high-pressure hydraulic hose for one and a half weeks or two weeks with thin iron sheet or PVC pipe (vertical cutting), fix them with iron wire, and then seal both ends of the PVC pipe with tape to avoid entering the mortar.

The hard core method adopts the core extrusion process to extrude the inner rubber tube blank, which directly uses the extruder to cover the inner rubber tube blank on the iron core, instead of the traditional casing process, and simplifies the process flow. Yinchuan Suction pipe The billet forming adopts the process method of intertwining outer film and steel wire braiding forming. Similar to wrapping water wrapped cloth, the overlapping width is 1/2 of the film width. This process method can replace the method of wrapping outer film by extruder or by hand, reducing energy consumption and cost. We all know that the reinforcing layer and reinforcing layer of the rubber hose are the main force bearing parts, which are used to bear the load pressure. The factors determining the stress condition of the reinforced layer of the rubber hose are determined by the tension of the braided steel wire and the braiding angle. The high-speed steel wire hose braiding machine developed by our factory has introduced the advanced technology of foreign braiding production lines, and integrated the characteristics of domestic braiding machines. It integrates the advanced functions of hydraulic brake hose braiding production line, such as horizontal mechanical transmission, automatic lubrication, and so on, to develop equipment with high productivity and high degree of automation. The range of braiding diameter can be achieved Ф 6— Ф 25 Long core rubber hose (reinforcement layer). It fills the gap of domestic knitting production equipment, which can be widely used in rubber and plastic hose, rubber hose (reinforcement layer) knitting production equipment. The structure of high-pressure rubber hose is composed of four parts: inner liner, inner rubber layer, skeleton layer, middle rubber layer and outer rubber layer. Suction pipe Price In case of direct contact with the conveying medium, the synthetic rubber with good medium resistance, high tensile strength, high constant tensile stress, small compression permanent deformation and easy processing is usually selected. In order to meet the use requirements of strong polar medium resistance, the inner liner is composed of polytetrafluoroethylene layer and rubber layer, and a layer of film or adhesive is added on the surface of the inner liner to improve the adhesion with the skeleton material.

high pressure wear-resisting Suction pipe There are many uses. When we choose products, understanding the basis for selecting production materials for high-pressure sandblasting hose will help us to select more suitable high-pressure sandblasting hose. The following small series will briefly introduce it to you: 1. The working environment of the product comes from the working environment of high-pressure sand blasting hose, such as outdoor environment, mechanical equipment, surface, etc. Considering these factors comprehensively, anti-aging and wear resistance shall be considered when selecting materials. 2. Function: From the performance of high-pressure hose, the main function of tubing is oil resistance, so the oil resistant material of material composition is the key.
