Abstract
The invention relates to an EVA (ethylene-vinyl acetate copolymer) adhesive particle heating pipeline. The pipeline comprises a pipeline body, wherein a high temperature resistant nano ceramic coating is coated on the surface of the inner wall of the pipeline of the pipeline body; further, a plurality of circular salient points are densely distributed on the surface of the inner wall of the pipeline of the pipeline body; the high temperature resistant nano ceramic coating is also coated on the surfaces of the circular salient points. The pipeline has the beneficial effects that the non-sticky coating (high temperature resistant nano ceramic coating) is arranged on the surface of the inner wall of the heating pipeline and a plurality of coarse salient points are also arranged on the surface of the inner wall and can avoid forming a smooth and dense contact surface between an adhesive body and the surface of the inner wall of the pipeline.
Description
Technical field
The present invention relates to a kind of water back, be specifically related to a kind of EVA micelle water back.
Background technology
If solar cell is directly exposed in air, its photoelectric transformation efficiency can decline very soon, loses practical value.Therefore, the research and development of the encapsulation material of solar cell are just very important.For reaching the object being isolated from the outside; adopt transparent, light aging resisting, adhesive property good, can bear atmosphere and change and there is flexible ethylene-vinyl acetate copolymer (EVA) glued membrane solar battery sheet is sealed; and be bonded together with levels protective material, form solar module.
EVA is a kind of typical random macromolecular compound, in its molecular structure, the irregular arrangement of substituting group on strand, in strand, the configuration of asymmetric carbon atom is not identical yet simultaneously, arrange also irregular, therefore it be that a kind of crystallinity is less, polarity and the higher material of pliability, it has good wellability when heating and melting in addition, during cooling curing, there is good flexibility, anti-stress cracking and adhesive property, be a kind of comparatively desirable can be for the material of solar cell package.
What EVA film forming adopted is extrusion forming process, and whole production line generally includes mixing plant, extrusion equipment, film pressing device, trimming unit and retractable volume equipment, completes batch mixing, material loading, extrudes, calendering, trimming, winding process.Determine will have of end product quality: raw material and formula, hot-melt extrusion process, and casting molding processes is controlled several aspects, and in casting molding processes process, environment temperature and humidity is also an important step, suitable humidity and stable temperature, the Shen of drawing that can reduce film is out of shape, the tension force of controlling diaphragm.
At present, in EVA production process EVA micelle in water back by the colloid of melt into molten condition.After shutdown, the EVA colloid of molten condition is caught a cold and is solidified, and can stick on inner-walls of duct.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of inwall can adhesion on the water back of EVA colloid.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of EVA micelle water back, comprise pipeline body, and the inner wall surface of the pipeline of described pipeline body is coated with high-temperature resistant nano ceramic coating.
Further, the composition that described high-temperature resistant nano ceramic coating is is zirconia and yittrium oxide compound.
Further, the inner wall surface of the pipeline of described pipeline body is densely covered with a plurality of circular salient points, and described high-temperature resistant nano ceramic coating is also coated in described circular bump surface.
The invention has the beneficial effects as follows:
The present invention is provided with non-sticking lining (high-temperature resistant nano ceramic coating) by the inner wall surface at water back, and is yet provided with a plurality of coarse salient points at table wall surface.Salient point can avoid forming between colloid and inner-walls of duct surface the contact-making surface of smooth densification.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, EVA micelle water back of the present invention is described further.
Fig. 1 is the structural representation of EVA micelle water back in embodiment.
The specific embodiment
Embodiment
Shown in Fig. 1, in the present invention, EVA micelle water back, comprises pipeline body 1, and the inner wall surface of the pipeline of described pipeline body 1 is coated with high-temperature resistant nano ceramic coating 2.
The inner wall surface of the pipeline of described pipeline body 1 is densely covered with a plurality of circular salient points, and described high-temperature resistant nano ceramic coating 2 is also coated in described circular bump surface.
The present invention is provided with high-temperature resistant nano ceramic coating 2 by the inner wall surface at water back, and is yet provided with a plurality of coarse salient points 3 at table wall surface.Salient point 3 can avoid forming between colloid and inner-walls of duct surface the contact-making surface of smooth densification.
The above-described embodiment that is not limited to of the present invention, all employings are equal to replaces the technical scheme forming, and all drops in the protection domain of requirement of the present invention.
Claims (3)
