Description

Cleaning method of spinning assembly

Technical Field

Background

Ultra-high molecular weight polyethylene (UHMWPE) fibers, also known as high-strength high-modulus polyethylene fibers, were developed in 1970 as high-performance fibers, which are white in appearance, and are considered as three major high-performance fibers that can be industrially produced at present, along with aromatic fibers and carbon fibers. Because the ultra-high molecular weight polyethylene fiber has excellent properties such as high strength, high modulus, small density, good impact resistance and chemical corrosion resistance, the ultra-high molecular weight polyethylene fiber is widely applied to the fields of light bulletproof helmets, soft bulletproof clothes and the like.

In the related art, the preparation process of the ultra-high molecular weight polyethylene fiber comprises the following process steps: preparing a spinning solution, adding an antioxidant, extruding and spinning by a double-screw extruder, quenching by a cold water bath to form gel precursor, extracting a solvent, drying, and carrying out hot drawing to obtain the ultra-high molecular weight polyethylene fiber. The ultra-high molecular weight polyethylene fiber usually needs to use a spinning assembly in the spinning process, and the spinning assembly generally comprises a feeding cover provided with a feeding port, a guide plate, a distribution plate, a spinneret plate and the like.

In the spinning production process, the mechanical impurities, gel, hot-cracking particles and other particles in the melt often block micropores on spinning components such as a spinneret plate and the like, so that the fineness of protofilaments is uneven, and defects such as injection heads, filaments and wool are generated, and therefore the spinning components such as the spinneret plate and the like need to be cleaned regularly. At present, a method for cleaning spinning components such as a spinneret plate and the like generally comprises a calcination method, wherein the calcination method utilizes high temperature to melt and carbonize organic matters covered on the metal surface before combustion, so that the spinning work of the spinning components such as the spinneret plate and the like is realized.

In view of the above-mentioned related technologies, the inventors believe that the method of cleaning the spinning components such as the spinneret plate by using the calcination method has a long cleaning period and consumes much energy, and when the local calcination temperature is higher than the metal oxidation temperature, the metal surface precision of the spinning components such as the spinneret plate is damaged, and the corrosion resistance of the spinning components such as the spinneret plate is reduced.
