Abstract

A production process for a KPE (Kelman Phacoemulsification) film relates to the technical field of production of solar photovoltaic back boards. The production process comprises the process steps of rolling, gluing, baking, pressing-in, unrolling and ageing, wherein the baking step is carried out in a baking oven; the baking oven comprises nine sections; and the temperatures of the baking oven from the first section to the ninth section are 30 DEG C, 40 DEG C, 60 DEG C, 80 DEG C, 80 DEG C, 85 DEG C, 85 DEG C, 95 DEG C and 100 DEG C sequentially. According to the production process disclosed by the invention, the performances of products are further improved by adjusting the reaction temperature of the baking oven and strip forces in both the TD direction and the MD direction can reach over 7 N.

Description

Technical field: [0001] The invention relates to the technical field of solar photovoltaic backplane production, in particular to a production process of a KPE film. Background technique: [0002] The solar photovoltaic backsheet is located on the back of the solar panel, and is applied to the backsheet of the crystalline silicon solar photovoltaic module, with white and dark gray and other colors. It mainly plays the role of weather resistance, mechanical strength resistance, water vapor penetration resistance and other properties. In the prior art, the production process steps of KPE film include winding, gluing, baking, pressing, winding and curing. In the baking step, the baking temperature is: 50°C, 55°C, 60°C, 70°C, 80°C, 85°C, 90°C, 90°C, 95°C. The performance of the produced KPE film is not ideal, the peeling force can only reach 5N in the TD direction, and only 5.5N in the MD direction. Invention content: [0003] The technical problem to be solved by the prese...
