Description
Technical Field
The invention belongs to the technical field of cleaning agents, and relates to a photovoltaic module cleaning agent, and a preparation method and application thereof.
Background
No matter be single glass assembly or dual glass assembly, in the lamination process, inevitably will have glued membrane (EVA or POE) to spill over to cause the pollution to glass surface, backplate surface and the inside of laminator. In the laminating process, under the action of temperature and pressure, EVA or POE generates a crosslinking reaction to form a three-dimensional network structure. Therefore, these residual glues are very difficult to clean, and a solvent is urgently needed by a component manufacturer for cleaning aid.
CN106914671A discloses a method for welding an outgoing line of an MWT photovoltaic module, which comprises the following steps: (1) welding surface treatment, namely if EVA residues exist at the bonding pad of the conductive foil, removing the EVA adhesive residues overflowing to the bonding pad by using an electric iron, then polishing the welding area of the metal foil, removing an oxide layer on the surface of the metal foil, and increasing the roughness of the welding area; (2) tin coating, namely coating tin on the rough dry surface obtained in the step 1, wherein the coverage area of a tin layer is a circle, the diameter of the circle is not less than 5mm, the height of the tin layer is uniform, and if the surface of the bonding pad is rusted during tin coating, a welding assistant pen is used for coating the bonding pad to remove the rust; (3) and (3) welding the lead wire on the surface treated in the step (2). The EVA adhesive residues in the invention are removed by using an electric iron, high temperature is required, the treatment is time-consuming and labor-consuming, and the method is not suitable for removing and cleaning the residual adhesive of the photovoltaic module.
Because the cull has formed three-dimensional network structure, ordinary solvent is difficult to be cleared up, is difficult to be cleared up with single solvent, needs multiple solvent to mutually support, just can have good clearance effect, just needs higher temperature just can the sanitization. However, if the cleaning temperature is too high, these solvents are volatile, and present certain hazards and corrosiveness to workers and equipment.
