Abstract

The invention relates to a uniform and stable ceramic precursor sol preparation device which comprises a double-layer reaction kettle, an acid medium storage assembly, pressurization equipment, a condensation pipe, a high and low temperature unit, a suction unit and a circulating cooling assembly, and the double-layer reaction kettle comprises a double-layer reaction kettle inner layer and a double-layer reaction kettle outer layer; an ultrasonic unit, an air injection plate and a stirring unit are arranged in the inner layer of the double-layer reaction kettle; the pressurizing equipment is connected with the inner layer of the double-layer reaction kettle through a pipeline so as to apply pressure to the spinnable ceramic precursor sol in the inner layer of the double-layer reaction kettle and promote the extrusion of the spinnable ceramic precursor sol; the condensation pipe is connected with the inner layer of the double-layer reaction kettle through a pipeline; compared with the prior art, the problems that the stirring is insufficient, the raw materials are not uniformly mixed, the pH value cannot be accurately controlled, and the spinnable ceramic precursor sol cannot be continuously produced by the current gel preparation device are solved.

Description

technical field [0001] The invention relates to a device for preparing a ceramic precursor sol, in particular to a device for preparing a uniform and stable ceramic precursor sol. Background technique [0002] Ceramic fibers have the characteristics of high melting point, high temperature resistance, high strength and high modulus, which make ceramic fibers have an important position in the field of high temperature resistant materials. The preparation methods of ceramic fibers mainly include melting method, sol-gel method, impregnation method, slurry method, Bunei door method and pre-polymerization method. At present, the sol-gel method is a widely used method for the preparation of continuous ceramic filaments, which can prepare continuous ceramic filaments with higher temperature resistance (above 1300 °C), and the filaments have high uniformity, mild reaction conditions, and sintering temperature. inferior advantages. [0003] However, in order to prepare spinnable pre...
