One, framematerial
Flat component must have frame, secure in order to protect the join of package and convenient component. The main material of frame has composite material of aluminium alloy, polyurethane, stainless steel, balata, increase plastic etc. The life of package basically gets the life that encloses material, life that encloses craft and the influence of use environment to enclose material among them is one of main factors that decide life of component of smooth hot season. 2, the action of frameBecause the edge of toughened glass and horn are flimsy, secure to protect the join of package and component and array, package needs frame. What frame makes pair of component with binder is sealed, what main effect body protects silica gel of the vitreous brim, integral machinery strength that increases package, union to hit an edge to enhance package now is sealed degree, install and carry of facilitating component. Main material has the frame of component of solar energy smooth hot season aluminium alloy, stainless steel and increase plastic etc. Frame structure should not stress position, avoid water, dirt or the stockpile of other object. Frame of polyurethane composite material is become by colophony and polymerization of fibre glass high temperature, have light qualitative, excel in, insulation, fight PID, be able to bear or endure ageing, anti-corrosive, fire prevention, be able to bear or endure it is high low temperature, good to can design a gender, the characteristic such as petty gain. Polyurethane composite material is the person above average in complex new material, generate electricity in aerospace, marine project, wind-force etc domain application is very wide. Whether can replace frame of smooth hot season and need of bracket of smooth hot season as to future from function, fall to wait for each respect to consider originally. 3, the function of frame1, pledge gently. Have steely 27% weight only, the 75% weight of aluminium alloy. 2, excel in. Combatting flexural strength is aluminium alloy 6 times much. 3, be isolated from. Polyurethane is compound the undesirable conductor that frame is heat and report, coefficient of thermal conductivity is the 1/640 of aluminium alloy only. The power station can fight be struck by lightning effectively. 4, fight PID. The bulk resistor rate of polyurethane composite material can amount to 1×1014Ω·cm, after component of smooth hot season uses metalloid frame to enclose, reduced the possibility that forms loop of leakage of electricity greatly, conduce to reduce PID electromotive force the generation of revulsive attenuation phenomenon. 5, be able to bear or endure ageing, anti-corrosive. In surface of polyurethane composite material besmear installed coating of polyurethane of ability in swimming later, this profile passed lamp of 6000 hours of xenon to accelerate ageing experiment, have be able to bear or endure first-rately await a gender. The wind leaf that traditional wind-force generates electricity is polyurethane composite material, fight ageing ability strong. 6, fire prevention. The fire prevention function of polyurethane composite material can reach B1 level flame retardant requirement. 7, be able to bear or endure on any account is lukewarm, be able to bear or endure microtherm below 150 degrees of 0 above. 8, it is good to can design a gender. Dimension shrinkage is the 1/3 of aluminium alloy, linear expansion coefficient is 1/3~1/4. 9, mechanical performance is superior, its axial tensile strength achieved the 7 times above of material of traditional aluminium alloy. In the meantime, its still are had very strong be able to bear or endure saline mist and be able to bear or endure chemistry corrodes function. 10, colour, burnish and exterior effect can choose neatly, satisfy diversification requirement; Have wonderful adherent property, and VOC is discharged extremely low.
