Description
Technical field
The utility model relates to a kind of applicator roll, particularly a kind of applicator roll that is used to make the solar battery group backboard.
Background technology
Along with the quickening of process of industrialization, energy resource consumption is increasing, and the finiteness that conventional energy resource is supplied with and the increase of environmental protection pressure impel the mankind to remove the development and utilization new forms of energy.Cause the attention in the world as the solar energy of one of new forms of energy.Industrialized country drops into huge fund one after another and researches and develops utilization, and attempt keeps it at leading position on the solar energy industry and the ascendancy on market.
Along with the proposition of low-carbon economy target, as the most potential energy of 21 century, the development potentiality of photovoltaic industry is huge.Along with growing continuously and fast of photovoltaic industry, the demand of its auxiliary products also increases day by day.The raw material of solar module production are polysilicon, cell package backboard, EVA glued membrane, face glass, electrode interconnecting strip, scolding tin and scaling powder etc.At present, the solar module raw material are not except that backboard also domesticizes, and other products are all realized production domesticization.Occupy an leading position with the import backboard in market at home, cost an arm and a leg, and all the other materials all need not import, adopts the production domesticization material significantly to reduce cost.Along with growing continuously and fast of photovoltaic industry, the demand and the production domesticization of its auxiliary products backboard are brought into schedule.Therefore, the special-purpose backboard production domesticization of solar module production is very necessary.
Existing import backboard is main with the film composite construction mainly, and wherein the Tedlar PVF film with Du Pont is main supplier, and two-sided compound PFT forms backboard through binding agent.The supply of material of TPT receives the production capacity restriction of DUPONT company to a great extent, and the supply of material is not very stable, and on the high side.And because use binding agent compound, very high to the weatherability requirement of binding agent, delamination appears easily.
As adopting coating processes, three layers of no plastic structure of original creation have obviously reduced the backboard layering.Surface filming is fine and close, has overcome the drawback of the easy layering bubbling of conventional adhesive composite membrane, has reduced the transmitance of basement membrane steam, has improved its weatherability.The fluorine rete is through specially treated, and any one side all can realize that perfection is bonding with any a qualified EAV glue, and with EVA very high peel strength is arranged, and greatly reduces the probability of happening that the assembly backboard bubbles.Concrete technology be with high-weatherability can the fluorine material, the PET film through coating processes and high barrier, high mechanical properties is combined into solar module special use backboard.
This material has ageing-resistant, corrosion-resistant, the performance and the excellent mechanical strength of PET polyester film such as resistant is hydrophobic of fluoroplastics high-quality, and it can prevent the erosion to silicon chip of solar cell such as other medium such as water, oxygen, corrosive gas, liquid (like acid rain) effectively.The weatherability of backboard, electric insulating quality, barrier, cementability satisfy the instructions for use of solar module fully.
In the conventional art, above-mentioned solar cell module back veneer adopts the PET film more, the production of the disposable completion backboards of step such as mistake unreels, preliminary treatment, coating, oven dry, side cut, arrangement, rolling.Yet adopting the solar battery group backboard of conventional art manufacturing all is flat back plate; And adopted the relatively poor PET film of heat dispersion; So the heat dispersion after it applies is poorer; When this backboard is used for solar battery group, can't effectively eliminate the negative effect that high temperature brought of solar battery group.
Summary of the invention
One of purpose of the utility model is to provide a kind of applicator roll, and it is used for applying the on-plane surface coating to basement membrane.
Two of the purpose of the utility model is to provide a kind of applicator roll, and its outer surface is provided with a baseplane and one group of patterning is protruding.
Three of the purpose of the utility model is to provide a kind of applicator roll, and it is specially adapted to make nonplanar solar cells group backboard.
Four of the purpose of the utility model is to provide a kind of applicator roll, adopts its solar battery group backboard that applies gained to have the nonplanar structure characteristic, thereby has good performance of heat dissipation.
To achieve these goals; The utility model discloses a kind of applicator roll; Its outer surface is provided with a baseplane and establishes one group of patterning protruding (patterned protrusion), and said patterning convexity is that striated convexity, rhombus are protruding, the convexity of block-shaped protrusion or other preset shapes.
Preferably, on the outer surface of said applicator roll, the area ratio between said baseplane and the said patterning convexity is 1: 1.
The utility model adopts applicator roll to make the on-plane surface backboard, has one group of patterning convexity on the said on-plane surface backboard, thereby increases the area of dissipation of backboard.Consider problems such as the intensity of backboard, follow-up transportation, installation, through the surperficial on-plane surface backboard of experiment convexity and the area ratio of non-convexity be 1: 1 o'clock, can above-mentioned factor be controlled at a safe range.
Below; To do further explanation through concrete embodiment; Yet embodiment only is giving an example of the optional embodiment of the utility model, and its disclosed characteristic only is used to explain and set forth the technical scheme of the utility model, and is not used in the protection domain that limits the utility model.
