5mm Sheet Glass Production Line 380V Sheet Glass Making Machinery for Window
1. Brief Description
Glass is a special amorphous inorganic nonmetallic material. The main component is silicate, a non-crystalline solid with an irregular structure.
Production process of sheet glass was created by Belgium Glaverbel Company in 1961. Under this kind of process, it can achieve a glass thickness from 0.8mm to 12mm.
The melting process is divided into five stages as following, each section has its inner connection, affecting each other. If one stage has imperfect performance, it will influence the next stage, and ultimately affect the quality of glass.
Physicochemical changes in each glass melting stage:
In this stage, the components of batched materials will produce a physicochemical solid phase reaction during heating process, in which the gaseous products will be released from the batched materials and produce a new opacity sinter ultimately, which is formed by silicate and SiO2.
In this stage, the sinter will be melting and the silicate and SiO2 in sinter will change to flint glass liquid with a plenty of bubbles. However, its chemical components and character are not even.
The glass liquid is continuously heated, and its viscosity is reduced with plenty of gaseous sundries released, which should eliminate the visible bubbles with the pool of liquid.
The glass liquid is kept at high temperature for a long time, the ripple eliminates by diffused function and homogenizes as a whole. The temperature of homogenization can be lower than the clearing stage.

5. Main Equipment Description
For batching and mixing the raw materials.
The melting tank is key part of glass production line, the refractory materials quality is very important.
Compared with the float glass process, the sheet glass is combined with slotless process and horizontal stretching process, forming the glass liquid by slotless tank and stretching rotation method.
In glass technology, annealing means to put the glass into the annealing lehr for a certain time or reduce the temperature with a slow speed, so as to no additional permanent stress or temporary stress will produce. Namely, annealing also means a process which will reduce or eliminate the thermal stress of glass.
6. Application
This type of ultrathin glass is mainly used for instrument, electrics and crafts manufacturing.
