Abstract
The invention relates to a production technology of carbon filament beating-up. The production technology comprises the following steps that 1, PAN protofilaments are divided into an upper layer and a lower layer, namely, the PAN protofilament layer containing singular numbers of the protofilaments and the PAN protofilament layer containing even numbers of the protofilaments according to the singular numbers and even numbers through a beating-up machine heald frame; 2, carbon fiber filaments or a weft storage mechanism with the carbon fiber filaments penetrates through openings of the upper layer and lower layer of the PAN protofilaments to make the carbon fiber filaments and the PAN protofilaments woven together; 3, the upper position and the lower position of the heald frame are exchanged, and then the positions of the upper layer PAN protofilaments and the lower layer PAN protofilaments are exchanged; 4, the carbon fiber filaments penetrate through the opening to be woven together with the PAN protofilaments. According to the production technology of carbon filament beating-up, the carbon fiber filaments and the PAN protofilaments are woven together, the problems that due to the fact that the property of the protofilaments is unstable and operation of equipment is unstable, when partial PAN protofilaments are broken, the PAN protofilaments are scattered in the equipment, or due to the fact that the manufacturing precision of the equipment is insufficient, the PAN protofilaments are overlapped, a fire or even an explosion is caused, and the carbon fiber filaments cannot operate normally are solved, the operability during filament breaking is improved, losses are reduced, and personnel safety is improved.
Description
Technical field
The present invention relates to the production technology that a kind of relevant carbon fiber production process, particularly PAN precursor beat up in preoxidation process.
Background technology
Carbon fiber (CarbonFibre) is fibrous material with carbon element, and in chemical composition, carbon accounts for more than 90% of gross mass.Carbon fiber and composite thereof have high specific strength, and high ratio modulus is high temperature resistant, corrosion-resistant, endurance, creep resistant, conduction, heat transfer, with a series of excellent properties such as thermal coefficient of expansion is little, they both as structural material bearing load, can play a role as functional material again.Therefore, carbon fiber and composite development in recent years very rapid.
Through development for many years, only have viscose glue (cellulose) base fiber, pitch fibers and polyacrylonitrile (PAN) fiber three kinds of raw materials to prepare carbon fiber technique at present and achieve industrialization.
And the primary necessary requirement that high-quality PAN precursor in the technique of carbon fiber is manufacture high-performance carbon fibre prepared by PAN fiber, this is the summary of many years of experience.But current, in the preparation of PAN precursor, Large Copacity is polymerized, the key technologies such as quick spinning fall behind, and cause properties of product unstable, cause uncontrollable fracture of wire, this gives the homogeneous pre-oxidation of carbon fiber, Quick Oxidation carbonization and other processes causes various problem, particularly to the preoxidation process fracture of wire of key, can cause on fire, the even irremediable loss such as blast.
Summary of the invention
For the above-mentioned technical problem of prior art, the object of this invention is to provide a kind of production technology that can reduce fracture of wire impact, the carbon filament that fracture of wire process becomes simple is beaten up.
For achieving the above object, the present invention is achieved by the following technical solutions:
The production technology that carbon filament beats up, comprises the following steps:
(1) by the machine heald frame that beats up, PAN precursor is divided into by single even numbers two-layer up and down, is respectively individual layer PAN precursor and double-deck PAN precursor;
(2) pass individual layer PAN precursor and double-deck PAN precursor opening by carbon fiber wire or with the Chu Wei mechanism of carbon fiber wire, be woven together with PAN precursor;
(3) exchange heald frame upper-lower position, thus individual layer PAN precursor and double-deck PAN precursor upper-lower position are exchanged;
(4) carbon fiber wire is passed opening, be woven together with PAN precursor;
(5) after completing steps (4), keep at a certain distance away, continue to repeat above-mentioned step of beating up (1)-(4), reach object of beating up.
Beneficial effect of the present invention is as follows:
The production technology that carbon filament of the present invention beats up, carbon fiber wire and PAN precursor are woven together, solve because of reasons such as precursor unstable properties and equipment fluctuations of service, when causing part PAN precursor fracture of wire, PAN precursor is scattered in equipment or device fabrication precision causes PAN precursor overlapping not, causes on fire, even blast waits the problem that carbon fiber line can not normally run, improve operability during fracture of wire, reduce loss, improve personnel safety.
