Problems solved by technology

Its shortcomings are: low production efficiency, low glass yield, environmental pollution, high energy consumption, long processing time, not suitable for modern processing technology
Its disadvantages are: it is easy to cause the chemical components sprayed on the lower layer of the glass to fall off and affect the stability of product quality. Long-term use will shorten the service life of the rollers, the main expensive parts in the tempering furnace.
Its disadvantages are: because of the spraying method, it is difficult to ensure the uniformity of the coating, and it is difficult to strengthen the strength of the glass in a short period of time.
After the PET film is pasted, it will affect the thickness and service life of the glass

Abstract

A super-hardness refrectory glass is prepared from the NaCaSi glass through cutting, fine grinding of its edges, heat treating in chemical gas phase containing K salt vapor, argon gas, gas-state copper chloride and N2, planting reflactory film and physically strengthening. Its thermodecomposing gasifying equipment consists of cylinder body, cover and reactor integrated with cylinder body.

Description

technical field [0001] The invention relates to the technical field of high-strength coating and fireproof glass, in particular to a manufacturing method and special equipment for superhard fireproof glass. Background technique [0002] At present, there are three types of fireproof glass commonly used in the construction field: composite, grouting, and wire. The disadvantages of the first two are that the service life is short, bubbles or discoloration appear after a period of use, and the light transmittance is low. The glass is thick and bulky. It is impossible to carry out large-scale industrial automation production by hand. The latter has poor transparency and limited thickness, so it can only be used in small areas. [0003] Chinese patent 01124523.9 discloses the "manufacturing method of silicate fireproof glass". The manufacturing method of salt fire-resistant glass, the manufacturing method is to select, cut, grind and polish the original glass, and then perfor...
