Dipping machine for producing continuous carbon fibers

Abstract

The invention relates to a dipping machine for producing continuous carbon fibers. The dipping machine comprises a dipping tank, a liquid storage tank and a circulating pump, wherein the dipping tank is positioned above the liquid storage tank; an inlet of the dipping tank is connected with an outlet of the liquid storage tank by the circulating pump; a concave overflow port is formed on two tank walls of the dipping tank vertical to a fiber running direction respectively; and circulation fluid in the dipping tank flows into the liquid storage tank through the overflow port. The dipping machine solves the technical problem that the conventional dipping equipment causes mechanical damage to fiber surfaces, and has the advantages of no mechanical damage to fibers, simple equipment structure, low manufacturing cost, good treatment effect and high treatment efficiency.

Description

technical field [0001] The invention belongs to the field of new material production, and relates to a carbon fiber production equipment, in particular to a liquid dipping machine for producing continuous carbon fiber. Background technique [0002] Carbon fiber is a new type of non-metallic material with a series of excellent properties such as high specific strength, high specific modulus, high temperature resistance, corrosion resistance, creep resistance, low thermal expansion, high electrical and thermal conductivity, and self-lubrication; and as a fiber, it also has Softness, weavability, and weaving are widely used in cutting-edge fields such as aerospace, national defense and military, as well as civilian industries such as high-end sporting goods and medical equipment. It has become one of the main reinforcements of advanced composite materials and is known as the mid-century The most vital new material. [0003] Since the rise of carbon fiber in the 1950s, its appl...
