Plate heat exchanger gaskets are an important part of the heat exchanger and have a significant impact on the service life of the plate heat exchanger; if these gaskets harden and lose their elasticity, they can lead to heat exchanger failure. Therefore, the sealing adhesive gasket is the most important and demanding accessory in the plate heat exchanger. The following is a brief introduction to the plate heat exchanger adhesive gasket processing process Qingdao Ruipute.

Rubber is a relatively complex polymer system, usually consists of rubber polymers, curing agent, filler, antioxidant, processing aids and thinners, etc. Although processing aids can not extend the life of rubber gaskets, but they can be used in the gasket manufacturing process to improve, extrusion and molding properties play a big role, the choice of raw materials and their proportion will determine the final performance of the rubber gasket material. Among them, natural rubber is made from latex of the Brazilian rubber tree and its basic chemical composition is cis-polyisoprene. Isoprene is a highly cis synthetic rubber made from isoprene. It is also known as synthetic natural rubber because of its similarity in structure and properties to natural rubber. Styrene-butadiene rubber is made by copolymerizing styrene with butadiene. According to the production method, it is divided into emulsion polymerized styrene butadiene rubber and solution polymerized styrene butadiene rubber. Butadiene rubber is produced by butadiene polymerization, compared with other general-purpose rubber, vulcanized butadiene rubber cold resistance, abrasion resistance and elasticity is much better, less heat under dynamic load, good aging resistance, easy and natural rubber, neoprene rubber, nitrile rubber and so on and use.

Usually, the manufacturing process of plate heat exchanger sealing gaskets includes five process steps.

1. The mixing step for mixing rubber, i.e. mixing various raw materials and auxiliary materials according to the formula.

2. Formation of rubber material blanks, i.e., rubber gaskets made of rubber material through extruder devices.

3. in the forming step, the vulcanized rubber gasket is placed in the 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 placed statically in the oven to complete the vulcanization.

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