Hot bending glass technology of double glass

Single glass and double glass processing is different, the single-layer glassregardless of the process or from the procedures are not complicated doubleglass, hot bending process of single glass only need to match the size, and the size of inter slice evenly with the silica glass is placed in the die, and then heated to its softening, so that the glass at temperature, glass in the self gravity or external pressure to achieve and die the same curvature, stop heating, slow annealing up to room temperature, thus finish bending processcan be, and double glazing requires from the many ways to do the double glass, processing mode can be divided into single, bending, bending two.

Common bending hot bending glass aquarium glass and glass counters, the biggest technical difficulty bending glass straight edge bending, corner at mark defect prone to die. The bent glass is also very common, such as spherical glass, turning arched corridor, glass wash basin, the glass in the bendingoperation requires a very high level of technology, production of precision molds, and some need to hot bending furnace professional to complete.

For the single bend of architectural glass, glass hot bending is relatively easy.But from the straight edge roughly 150mm curve many manufacturers often inedge, not with the mold very well, some have exceeded the standard requirements, which causes the difficult installation. To solve this problem, first requests the electric heating arrangement hot bending furnace must be reasonable, can realize the local heating, placement direction products should be consistent with the direction of the electric heating wire.

In general, want to grasp the hot bending process of double glass, only a good grasp of temperature it, otherwise easily lead to hot bending glass shape and technology appear in all kinds of different problems.
