1. Introduction to hot bending glass:
Hot bending glass is a flat glass heating softening, forming in a mold. The curved glass is made by annealing. The hot bending glass can be made into various curved glass. The hot bending glass can be used as a sightseeing elevator, a hall hall, and a rotating top layer. , roof lighting, crossing passages, viewing windows, etc., can also be used for furniture coffee tables, shower rooms, containers and so on.
The forming temperature of hot bending glass is generally around 580 °C, mainly near the softening point of glass. Mastering the molding temperature and strict model making are the key to hot bending glass forming. It is necessary to properly grasp the time of glass bending molding to ensure the time. Production quality.
Generally, the main tools for making hot-bent glass are steel for electric making, electric welding machine, pipe bending machine, cutting machine, etc. The material used for hot bending glass is first to use glass with different thickness, followed by release agent. High temperature glass cloth and other materials.
4. Temperature control of hot bending glass
The forming temperature of the hot bending glass is about between the softening transition point of the glass. It is about 580 ° C. The molding temperature is inversely proportional to the time. The higher the temperature, the shorter the time, the lower the temperature, the longer the time. For a special curved glass, It must be heated by local heating or by external force.
