Gasket of the plate heat exchanger is an important part of the heat exchanger, which has an important impact on the service life of the plate heat exchanger. If these gaskets harden and lose their elasticity, it may lead to the failure of the heat exchanger. Therefore, the sealant strip is the most important and demanding accessory in plate heat exchanger. Here is a brief introduction of Qingdao ruipute plate heat exchanger rubber processing technology.

Qingdao ruipute plate heat exchanger gasket

Rubber is a relatively complex polymer system, which is usually composed of rubber polymer, vulcanizing agent, filler, antioxidant, processing aid and diluent. Although processing aid can not prolong the service life of rubber gasket, they can be used to improve, extrude and mold pressing performance in the manufacturing process of gasket. The selection and proportion of raw materials will determine the material of rubber gasket of plate heat exchanger. The final performance of the system. Among them, natural rubber is made from latex of Hevea brasiliensis, and its basic chemical composition is cis isoprene. Isoprene is a high CIS synthetic rubber made from isoprene. Because its structure and properties are similar to natural rubber, it is also called synthetic natural rubber. Styrene butadiene rubber is prepared by copolymerization of butadiene and styrene. According to the production method, it is divided into emulsion polymerized styrene butadiene rubber and solution polymerized styrene butadiene rubber. Cis-1,4-polybutadiene rubber is made by polymerization of butadiene. Compared with other general-purpose rubber, the vulcanized cis-1,4-polybutadiene rubber has better cold resistance, wear resistance and elasticity, less heat under dynamic load, good aging resistance, and is easy to be used together with natural rubber, chloroprene rubber, nitrile rubber, etc.

Generally, the manufacturing process the gasket plate heat exchanger of includes five steps

1. The mixing step of mixed rubber is to mix various raw materials and auxiliary materials according to the formula;

2. Forming a rubber material blank, that is, the rubber material is made into a rubber strip through an extruder device;

3. In the forming step, the vulcanized rubber strip is put into the die cavity of the hot die, the die is closed for vulcanization, and the rubber gasket is formed in the stamping equipment;

4. After vulcanization, the vulcanized gasket is statically placed in the oven to complete vulcanization;

5. Finished product inspection, that is, according to the process standard to take out some finished products for finished product inspection.
