The impregnating compound preparing system sequentially comprises a feeding system, a reaction tank, a mixing tank and a distribution pipe from top to bottom, wherein the feeding system comprises feeding tanks, stirring devices I, heating sleeves I, liquid level sensors I, water inlet pipes I and discharge pipes I, part of the discharge pipes I converges at the feed inlet of the reaction tank, and the rest of the discharge pipes I and a discharge pipe II converge at the feed inlet of the mixing tank; the reaction tank is provided with a stirring device II, a blowing ring, a liquid level sensor II, a heating sleeve II, a water inlet pipe II and the discharge pipe II; the mixing tank is provided with a stirring device III, a liquid level sensor III, a heating sleeve III and a discharge pipe III, and liquid level sensors and valves are connected with a PLC. The impregnating compound preparing system has the advantages that optimal dissolving and reaction temperature is provided for an impregnating compound, the impregnating compound is directly conveyed into a draw bench, automatic preparation is achieved, and the production efficiency and quality of the basalt fibers are increased.

Description

technical field [0001] The invention relates to the field of processing inorganic non-metallic materials, in particular to a sizing preparation system for producing continuous basalt fibers. Background technique [0002] The continuous basalt fiber is made of natural volcanic extrusive rock as raw material, which is crushed and put into the melting furnace. After melting at 1450-1500 ℃, it is a continuous fiber made by drawing bushings. Compared with carbon fiber, aramid fiber, ultra-high molecular weight polyethylene fiber (UHMWPE) and other high-tech fibers, it has many unique advantages, such as good mechanical properties, good high temperature resistance, and can be used continuously in the range of -269 to 650 °C. Work, acid and alkali resistance, strong UV resistance, low moisture absorption, better environmental resistance, in addition, it has good insulation performance, high temperature filterability, radiation resistance, good wave transmission performance and othe...

AI Technical Summary

Problems solved by technology

[0003] In the process of producing continuous basalt fiber, the tow coming out of the liquid-leaking drawing board needs to be coated with sizing agent. The preparation of the existing sizing agent is complicated, labor-intensive, and reduces the production efficiency of basalt fiber.
