Abstract

The invention discloses a dustproof film, photovoltaic module glass and a use method. The dustproof film comprises a dustproof layer and a polyurethane elastomer bonding layer arranged on the dustproof layer. When the dustproof film is applied to the photovoltaic glass transportation process, the problem of smudginess in the photovoltaic glass transportation process can be solved, and the glass feeding time and the transportation cost are saved. When the dustproof film is applied to photovoltaic module manufacturing, the problem of smudginess of photovoltaic module glass in the manufacturing process can be solved, and the product yield is improved; the cleaning period of equipment such as a laminating machine and an assembly line can be prolonged, the cleaning time before the photovoltaic module is delivered is shortened, and the manufacturing cost of the photovoltaic module is further greatly reduced.

Description

technical field [0001] The invention relates to a dust-proof film, a photovoltaic module glass and a method for preparing a photovoltaic module. Background technique [0002] The lamination of photovoltaic modules is to laminate crystalline silicon cells, tempered glass, and packaging materials (EVA, backplane, etc.) in different orders to form a finished product. During the process of photovoltaic modules (lamination, assembly line, framing, testing, etc.), there are often hot-melt adhesives or other possible dirt that cause glass contamination, which is difficult to clean. In the prior art, in order to avoid contamination, the cleaning frequency of the manufacturing equipment and the assembly line can only be increased, which consumes manpower and equipment production time, reduces the utilization rate of the equipment, and causes a substantial increase in manufacturing costs. At the same time, this method cannot avoid the front glass possibility of contamination. Conte...
