Glass film heating and curing process

Abstract

The invention provides a glass film heating and curing process which comprises the following steps that a glass plate enters a furnace chamber of a curing furnace, and a lifting conveying device and an infrared heating pipe are arranged in the furnace chamber, the infrared heating pipe is used for heating a film on the surface of the glass plate, and the lifting conveying device is used for driving the glass plate to move vertically. According to the glass film layer heating and curing process, the infrared heating pipe is used for heating the film layer on the surface of the glass plate, theinfrared radiation heating and curing process is adopted, the heating efficiency is high, the film layer can be dried from inside to outside through the heating mode, pinholes and other defects are not likely to be formed, and therefore the curing quality of the film layer is improved. Meanwhile, according to the glass film layer heating and curing process, the adopted curing furnace is short in length in the horizontal direction and small in occupied area, the area of a plant area is saved, and the space in the height direction of the plant area is fully utilized.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a glass film heating and curing process. Background technique [0002] The light transmittance of ordinary ultra-clear embossed glass is only about 91.5%. At present, a popular method in the industry is to coat a layer of anti-reflection film on the sunlight incident surface (front glass) of solar packaging glass to improve the transmittance. The light rate, increase the output power of the battery module and reduce the electricity cost per kilowatt-hour of the module. The anti-reflection coating can increase the transmittance by 1.8% to 3.0%, and the output power of the crystalline silicon battery module can also be increased by 2% to 4%. In addition, With the popularity of solar double-glass assemblies, the demand for screen-printed backplane glass is also increasing. The coating process generally goes through preheating, coating, curing and other processes. [...

AI Technical Summary

Problems solved by technology

[0003] In the traditional film curing process, the glass is heated and cured in the roller table conveyed horizontally, and the heating tube is arranged above the roller table to radiate the glass, which is limited by the arrangement of the equipment, and the energy consumption is high; in addition, because the film layer It takes a certain amount of time to complete the curing, and it takes a long time to complete the method of horizontal roller conveying, which will increase the length and cost of the equipment in the horizontal direction, and will also increase the demand for the area of ​​the factory building. Used in small factories

In addition, the traditional curing process is affected by its heating method, resulting in poor curing quality of the film layer, especially the film layer is prone to defects such as pinholes during the curing process
