    SINOYIN QUALITY

    Material Equipment

    Quality Control from the source- Copper Tubes

    *Copper tube adopts TP2 copper oxidation resistance, corrosion resistance is strong.
    TP2 copper excellent welding performance, welding node good ductility;
    *Copper adopt domestic brand copper suppliers, to ensure the quality of copper;
    *Copper wall thickness are above 0.6 mm to ensure the sealing of copper pipe flow;

    Solar Industry Disclose
    1, In order to reduce costs, some manufacturers use inferior copper pipe instead of high quality copper pipe;
    2, In order to reduce costs, some factory products are inconsistent with the contract requirements, when mass production, some factories changecollectors inside diameter and wall thickness of the copper pipe;
    Solution: sample testing ( random testingq when massProduction )

    Quality Control from the source - Aluminum Alloy Frame
    * 6063 - T5 aluminum hou resistance is strong, high mechanical strength, is the guarantee of flat collector sturdy and durable ;
    * Aluminum surface oxidation treatment,surface generates a layer of protective film layer, to ensure that the plate collector to adapt to the harsh outdoor environment;
    * Our aluminum alloy frame from domestic brand aluminum suppliers.

    Quality Control from the source - Absorber Material
    Absorber is used with imported Germany high efficiency bul titanium, it is of high absorbility, low emissvity, α≥95%, ε≤5%, stable performance.

    Quality Control from the source - Absorber Material
    The material is EPDM with the good & reliable famous brand supplier,it is of Anti High temperature, weather resistance, uvioresistant,can be more than 20 years working life.

    Quality Control from the source -Glass cover
    It is used 3.2mm low iron braided tempered glass, the light transmittance can upto 91.2%, also the matted finish on the glass can prevent the second reflex, more important, the hardness of the tempered glass is 5 times harder than normal glass.

    Quality control from the source - thermal insulation material
    *Insulating materials use glass fiber cotton and stearic foam polyurethane
    *Glass fiber cotton high temperature resistance, ageing resistance, coefficient of thermal conductivity is 0.042 W/M * h * ℃, insulation Can good, high hydrophobic, cost-effective;
    *Hard foam polyurethane, coefficient of thermal conductivity is 0.027 W/M * h * ℃;
    *Our insulation materials are from domestic brand suppliers;
