Description
Technical field
The present invention relates to solar double-glass assemblies technical field of measurement and test, particularly to a kind of solar double-glass assemblies edge steam penetrating power
Semidefinite weight testing method.
Background technology
Photovoltaic double-glass assembly has that product power attenuation is few, anti-pid ability strong, anti-wear performance, water vapor transmittance are low, weather-proof
Performance is better than traditional components, reduce simultaneously fluorine material contamination be more easy to reclaim, applied range the advantages of, double glass will be by from now on
Widely apply and promote, but because double glass eliminate the aluminum alloy frame of surrounding, so the packaging adhesive film of the about 0.5mm of edge
Directly it is connected with air, how to assess glass edge to the distance of interiors of products chip, make the speed that micro steam permeates
Under degree, its distance does not reach the chip edge of inside it is ensured that double glass product is not all affected in whole life cycle,
It will be the problem that product design personnel need to solve.Multi-vendor greatly designer is qualitative supposition by rule of thumb or imitates at present
The mode that colleague plagiarizes is carried out, or it is larger to make product there is risk, or being exactly surdimensionnement, increases product cost；This
Bright can design is a kind of semiquantitative method of testing of simple and efficient, to confirm glass edge arrive solar double-glass assemblies inside chip away from
From, while meeting product safety creep age distance, making the infiltration of steam in lifetime not affect phase properties.
Multi-vendor greatly designer is that the qualitative mode speculating or imitating that colleague plagiarizes is carried out by rule of thumb at present,
Making product there is risk larger, or being exactly surdimensionnement, increasing product cost.
And pct testing machine is generally arranged in supporting table, connected by connecting piece between them, connecting piece is easily damaged portion
The knockdown pieces of position, in use it occur frequently that producing very big strain and projection towards the rear, such strain usually makes
Obtain the dismounting of pct testing machine to be not easy, or even connection is damaged for it.
