Abstract

The invention relates to a material static mixer for aramid fiber pre-polymerization, and belongs to the technical field of static mixer equipment. The bottom of the mixing chamber of the static mixer is provided with a piston rod pushing chamber. The inner wall layer and the external wall layer of the mixing chamber are arranged between the mixing chamber inner cavity and the piston rod pushing chamber. The bottom of the mixing chamber inner cavity is provided with a piston head, the bottom the piston head is connected to a piston pushing rod, and the piston pushing rod goes through the inner wall layer and the external wall layer of the mixing chamber and extends from the mixing chamber to the piston rod pushing chamber. The bottom of the piston rod pushing chamber is provided with a sealing flange. The static mixer can remove the oligomer sediment, prevents the continuous material leaking to reduce loss, and is capable of guaranteeing the rapid and continuous reactions.

Description

technical field [0001] The invention relates to a material static mixer, more specifically, the invention relates to a material static mixer used for aramid fiber II prepolymerization, which belongs to the technical field of static mixer equipment. Background technique [0002] DuPont published a high-performance poly-p-phenylene terephthalamide fiber in 1966. Its official product name is Kevlar fiber, which is referred to as para-aramid fiber, aramid fiber 1414 or aramid fiber II in China. Because of its high strength, high modulus and high temperature resistance, it is widely used in tire cords, high-strength rigging, high-pressure container shells, automobile friction plates, construction geotechnical materials, various reinforced composite materials instead of steel, transportation belt, special canvas, etc. In the military, such as making body armor, helmets, missile shells, armor plates, radar device covers, etc. Because of its wide range of uses, it was once called ...
