Product Description

Plates are an important component of plate heat exchangers. Their main functions are to isolate media and conduct heat exchange. The main materials of plates include stainless steel (304/304L, 316/316L, 254SMO), titanium, nickel, titanium - palladium alloy, Hastelloy, etc.

I. Composition of Plates

Each plate consists of two components.

1. Metal Plate: The metal plate is a thin metal sheet with corrugations, sealing grooves, and corner holes pressed on it. It is an important heat - transfer element. The corrugations can not only enhance heat transfer but also increase the strength and rigidity of the thin plate, thereby improving the pressure - bearing capacity of the plate heat exchanger. Moreover, they can make the liquid flow in a turbulent state, reducing the formation of sediments or fouling and playing a certain "self - cleaning" role.
2. Sealing Gasket: It is installed in the gasket groove around the plate, sealing the periphery between the plates to prevent fluid from leaking outwards (click to view the causes and solutions for external leakage of plate heat exchangers). According to the design requirements, it also seals some of the corner holes, enabling hot and cold media to flow in their respective channels.

II. Plate Manufacturing

Plates are all formed by stamping at one time using a mold. Only plates formed at one time have the same precision. Therefore, there are uniform metal point contacts between plates, ensuring that the plate heat exchanger can operate normally under relatively high pressure and withstand the pressure impact of the system.

The gaskets of plate heat exchangers are a relatively complex polymer system, usually composed of different components such as rubber polymers, vulcanizing agents, fillers, anti - aging agents, processing aids, and diluents. Although processing aids cannot extend the lifespan of rubber gaskets, they are very effective in improving the mixing, extrusion, and compression molding properties during gasket manufacturing. The selection of raw materials and their ratios will determine the final performance of rubber gasket materials.

Natural rubber is obtained from the latex of the Hevea brasiliensis tree, and its basic chemical composition is cis - polyisoprene. Isoprene rubber is a high - cis synthetic rubber made from isoprene. Due to its structure and properties being similar to those of natural rubber, it is also known as synthetic natural rubber. Styrene - butadiene rubber is copolymerized from butadiene and styrene, and it is divided into emulsion - polymerized styrene - butadiene rubber and solution - polymerized styrene - butadiene rubber according to the production method.

Butadiene rubber is obtained by polymerizing butadiene. Compared with other general - purpose rubbers, vulcanized butadiene rubber has particularly excellent cold resistance, wear resistance, and elasticity. It generates less heat under dynamic load, has good anti - aging properties, and is easy to be used in combination with natural rubber, neoprene, nitrile rubber, etc.
