High-pressure steel wire winding hose manufacturers explain the classification of hoses to you

Supply a wider range of water to the rubber tube sandwiched by the cloth, industrial water, mud, hydraulic oil, emulsified oil, hot water sweeping steam, etc. can use large-diameter rubber tubes. Under the circumstance, the products with more exports are steel rubber hoses, ordinary rubber hoses, etc., and the high-tech automotive rubber hoses are less exported, and the proportion of chemical fiber wound pipes, braided pipes, braided pipes, wound pipes and resin pipes in the pipes exceeds 60%. Close to the international advanced level, because the product structure is in line with international standards, it is beneficial to the export of my country's rubber tube products. The production capacity of main rubber pipe products ranks first in the world. my country's rubber pipe products already have the basic conditions for a large number of exports, but the actual export volume is still very small. In recent years, the annual export value of rubber pipes only accounts for less than the total annual export value of rubber products. 1%, which is 9.5% of the annual export value of tires and 1.4% of the annual export value of rubber shoes. In addition, it is estimated that the export value of my country's rubber tube products accounts for about 10% of the total output value. Manufacturer of high-pressure steel wire winding hose: hose forming process The basic process of rubber hose production is mixing rubber processing, fabric and canvas processing, hose forming, vulcanization, etc. The structure and skeleton of the rubber hose are different, and the processing method of the skeleton layer and the hose forming equipment are different. Since all rubber hoses do not contain a skeleton layer, the extruder can be used to extrude the hose; the cloth-covered hose needs to use a molding machine that wraps the rubber cloth in the rubber layer; the suction hose needs to be wrapped with a metal spiral when forming Inner rubber; the weaving and winding of the hose requires the use of a special fabric braiding machine or coiler; knitting the hose requires the use of a braiding machine, etc. The forming method of the hose is mainly whether to use a mold, which is divided into coreless method and core method (including soft core method and hard core method). Manufacturer of high-pressure steel wire wound hose: coreless forming The coreless molding of the hose is performed by an extrusion molding machine (commonly used screw extruder), and the skeleton layer and the outer rubber layer are directly formed on the extruded inner hose. Through the placement of the extrusion screw, it is stirred, mixed, plasticized, and extruded in the cylinder to move it toward the head, and extruded from the lamp head. The product of a certain shape, the screw extruder is divided into hot feed and cold There are two kinds of feeding, the former provides the conditions of preheating with an open mixer, and the latter provides the rubber material without heat stirring. Manufacturer of high-pressure steel wire winding hose: forming with core The forming of the rubber hose with a core means that the rubber hose is formed into a hard core or a soft core. In order to ensure that the rubber hose is in a compressed state during the vulcanization process, the rubber hose is wrapped with water cloth (a roll of wet cloth with a width of about 10cm), rope or lead. vulcanization. Vulcanization can be directly steam heated or continuously vulcanized in a vulcanization tank. The short fiber hose is directly put into the rubber material and extruded to form. The manufacturing process is simple, and it can gradually replace the braided hose and the clamping hose. The production technology tends to be highly continuous and automated. The use of thermoplastic rubber and plastics can save the vulcanization process and greatly simplify the production process.

What is the production process of high pressure hose

There are many high-pressure hose manufacturing equipment, many types of raw materials, and complex production processes. However, in recent years, the production process of high-pressure hoses with plastics or thermoplastic elastomers as the main raw materials can be appropriately simplified, but the price of raw materials is relatively high, and rubber raw materials are still the main raw materials. What are the main production processes of high-pressure hoses?
