What is a pp melt blown filter cartridge machine

According to the principle of gradual diameter, the pp melt blown filter cartridge machine can accurately control the amount of material and temperature through various control systems. It can produce filter elements with complex processes. It adopts an electric heating temperature control.

The melt blown process is a kind of polymer extrusion non-woven process. It originated in the early 1950s. In order to collect radioactive particles from nuclear tests, the U.S. Naval Laboratory began to develop filter materials with ultra-fine filtration effects. 1954 Published research results in the year. my country's melt blown technology originated in the late 1950s and early 1960s, and the equipment studied was intermittent. By the end of the 1960s and the beginning of the 1970s, the number of batch melt blown equipment in China had reached more than 200. In 1992-94, continuous production lines were introduced from the United States and Germany. So far, it is estimated that there are still more than 300 intermittent melt blown equipment in operation across the country.

In theory, all thermoplastic polymer chip raw materials can be used in the manufacturing process of melt blown filter elements. Polypropylene is one of the most widely used chip materials for melt-blown technology. In addition, the commonly used polymer chip materials for melt-blown technology include polyester, polyamide, polyethylene, polytetrafluoroethylene, polystyrene, PBT, EMA , EVA, etc. Olefin polymer raw materials (such as polypropylene) have a high degree of polymerization, so the heating temperature is higher than its melting point 100 or higher can be melt blown smoothly, while the polyester heating temperature is slightly higher than its melting point can be melt blown. Olefin raw materials generally do not need to be dried.System and has a good heat preservation effect, which can reduce heat loss. Reduce production energy consumption.
