A kind of preparation technology of cesium potassium laminated fireproof glass

Abstract

The invention relates to the technical field of glass processing and manufacturing, in particular to a preparation process of cesium potassium interlayer fireproof glass, comprising the following preparation steps: S1 cutting: cutting the original glass plate to obtain a glass substrate; S2 edging: cutting Good glass substrate is subjected to edge grinding treatment; S3 acid treatment: acid treatment is carried out on the glass substrate after edge grinding; S4 ion exchange treatment: soaking the preheated glass in an ion exchange tank filled with cesium potassium salt solution Carry out ion exchange treatment; S5 tempering heat treatment: send the ion exchange treated glass into the tempering furnace for heat treatment; S6 air-cooling forming: take out the tempered glass and send it to the bellows for air-cooling forming to obtain tempered cesium Potassium glass; S7 interlayer: place the interlayer film between two pieces of tempered cesium potassium glass for lamination; S8 pressure. The process of the invention is simple, and the prepared cesium potassium interlayer fireproof glass has strong pressure resistance and heat resistance, is not easy to burst, and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of glass processing and manufacturing, in particular to a preparation process of cesium potassium interlayer fireproof glass. Background technique [0002] Fireproof glass is a kind of building exterior wall or door and window glass with fireproof function. It can generally keep for a long time without bursting under the impact of flames at 600-1000°C, so as to effectively prevent the spread of flames and dense smoke, and ensure the safety of people's lives and property. has a vital role. Fireproof glass is generally divided into single-layer fireproof glass, wire fireproof glass, hollow fireproof glass and composite fireproof glass. According to survey data, among the fire-resistant glass produced in my country, single-layer fire-resistant glass accounts for about two-thirds of the total fire-resistant glass, and composite fire-resistant glass only accounts for one-third. In fact, single-layer fire-resista...

Problems solved by technology

According to survey data, among the fire-resistant glass produced in my country, single-layer fire-resistant glass accounts for about two-thirds of the total fire-resistant glass, and composite fire-resistant glass only accounts for one-third. In fact, single-layer fire-resistant glass and composite fire-resistant glass have their own Advantages: Among them, the single-layer fireproof glass is easy to deep process, the thickness is generally between 6 and 19mm, and its hardness is generally about 1.5 to 3 times that of tempered glass. It can only meet the integrity of fire resistance, and it does not have the purpose of heat insulation. A large amount of heat can be transferred from the fire area to the non-fire area through it; while the fire resistance of composite fireproof glass can reach more than 180min, and it is generally made of float glass. Between 10 and 62mm, it can meet the requirements of fire-resistant integrity and heat insulation. Only very little heat can be transferred from the fire area to the non-fire area through it, and its sound insulation effect is good, and it can withstand various pressures. It is easy to turn milky white and produce air bubbles under irradiation, blocking the line of sight
