General light rubber sheathed cables are used in daily-use electrical appliances and small-sized electrical appliances, and are required to be soft, lightweight, and have good bending performance;
Medium rubber cable is widely used in agricultural electrification except for industrial use;
Heavy-duty cables are used in applications such as port machinery, searchlights, and large-scale hydraulic irrigation and drainage stations in the home industry. This kind of product has good versatility, complete specifications, good performance and stability.
First, equipment: Small-scale pressure equipment with automatic temperature control, timing and multi-size tubular cavity.
Second, the rubber material: consistent with the wire of the wire, and the glue content is higher than the material, the vulcanization system is slightly stronger.
Third, the operation method:
1. Set the temperature and time according to the vulcanization system of the rubber material. 2. Use a rubber ink thinner to wash the repaired area, especially the joint area.
3, according to the size of the gap to cut the amount of repair rubber, pay attention to not too much or too little,
4. Put the cut plastic material in the gap, and pay attention to that the rubber material should not be higher than the circumferential surface of the wire.
5, wrapped with high temperature PP tape. And put it in a tubular mold cavity slightly smaller than the wire diameter, and lock the upper and lower molds, so that the position to be filled with a certain pressure. Note that the cavity diameter is slightly smaller than the wire diameter by 0.1~0.2mm.
6, until the vulcanization time is reached, remove the product, if there is a small amount of rubber spills, use a sharp blade to complete, and dilute with a diluent.
Fourth, verification method:
Press the appropriate amount of air into the filled wire and place it in water.
The wire and cable industry is China's second largest industry after the automotive industry, with product variety satisfaction rates and domestic market share exceeding 90%. In the world, China's total output value of wire and cable has surpassed that of the United States and has become the world's largest wire and cable producer. With the rapid development of China's wire and cable industry, the number of newly added companies has continued to rise, and the industry’s overall technological level has been greatly improved.
The sustained and rapid growth of China’s economy provides a huge market space for cable products. The strong attraction of the Chinese market has led the world to focus on the Chinese market. In the short period of reform and opening up, China’s cable manufacturing industry The huge production capacity created makes the world impressive. With the continuous expansion of China's power industry, data communication industry, urban rail transit industry, automobile industry and shipbuilding industry, the demand for wire and cable will also grow rapidly. The wire and cable industry in the future will have enormous potential for development.
Calcined aluminum oxide has the advantage of quite small coefficient of expansion, excellent hydrophilicity, great toughness and great great strength. Calcined Aluminum Oxide Abrasive Cloth usually used for polishing stainless steel, hard metal, titanium alloy, casting metal and welding lines.
Abrasive Cloth is the cloth with grinding compound. According to the different grinding compound, the abrasive cloth can divided into four kinds: Aluminum Oxide Abrasive Cloth, Silicon Carbide Abrasive Cloth, Zirconium Oxide Abrasive Cloth and calcined aluminum oxide abrasive cloth and so on. According to the hardness, it also can be divided into flexible abrasive cloth,middle flexible abrasive cloth and hard abrasive cloth. Some of them can do waterproof or oil-proof. The shape of the abrasive cloth is roll, belt and sheet. The abrasive cloth is generally used for wood grinding and metal grinding. It can available in vary grits.
After 30 years` development, abrasive cloth grinding has become a complete and self-contained system of new processing technology. Because of its high processing efficiency, wide application range, strong adaptability, low cost, safe and convenient operation, it is well received by customers. In foreign countries, Abrasive Belt grinding technology has made great progress. It can be applianced for more and more processing object . It can process almost all engineering materials, from the general daily life appliance to application of large aerospace equipment.
