Problems solved by technology

Of course, the first type of technology also has some shortcomings, mainly in: 1. The yield of zirconia ceramic ferrule blanks is low
2. The formula of raw materials for making the zirconia ceramic ferrule blank is complicated, and the mechanism is not clear, so a lot of experiments are needed to obtain
The second type of technology is not currently the mainstream technology in China, and there are few related researches, and the technology needs to be perfected
but still no theory on how to tune these parameters

Abstract

The production process of zirconia ceramic ferrule blank adopts a unique raw material formula, after mixing and granulation, it is injection molded at a low speed at an injection molding temperature of 165-180°C and a molding pressure of 0.8-1.2Mpa, and adopts a six-stage temperature control method Degreasing and sintering in six-stage temperature control mode to form zirconia ceramic ferrule blanks. This method has stable process and improves the problems of low labor productivity, high cost, complicated control, low blank yield, and insufficient performance such as hardness and compactness in existing methods. .

Description

technical field [0001] The invention relates to the technical field of production and manufacturing of zirconia ceramic ferrule, in particular to a production process of zirconia ceramic ferrule blank. Background technique [0002] Zirconia ceramic ferrule blanks are the main raw materials for manufacturing optical fiber ferrules. At present, there are two main types of processes for manufacturing zirconia ceramic ferrule blanks. The first category is the production of zirconia ceramic ferrules by unidirectional positioning and hot-melt injection molding. Blanks, the second category is the production of zirconia ceramic ferrule blanks by two-way positioning dry powder dry pressing method. The first type of technology has been widely used in China because of its early appearance, stable process and mature equipment. Of course, the first type of technology also has some shortcomings, mainly in: 1. The yield of zirconia ceramic ferrule blanks is low. 2. The formula of the raw...
