This product is a milky white liquid obtained by reacting hollow silica nanoparticles with active groups with organic matter. It is coated on the glass surface by roller coating process, and after medium temperature curing and high temperature sintering, the organic matter is completely burned off, the nanoparticles will be precisely combined with each other and rely on the hollow structure of the silica nanoparticles to produce a lower refractive index of the film layer.
JUNHE®9680 high-reflective glaze is applied to the backplane glass of photovoltaic dual-wave modules. Its main components are titanium dioxide, low-melting glass powder, organic binders, additives, etc. It is coated on the glass surface through silk screen printing. After the glass is tempered at high temperature, organic matter The inorganic materials that are volatilized by carbonization and remain adhere to the glass, achieving the characteristics of high reflection, high weather resistance and corrosion resistance of the glaze.
JUNHE®2610 no-clean flux is a low-solid, halogen-free, water-soluble flux, suitable for solar cell welding and automatic welding by immersion or spray coating. This flux does not contain rosin, and the solder joints after welding are full and bright. There is little residue on the board surface and it has extremely high surface insulation resistance.
JUNHE®2550 monocrystalline texturing auxiliary additive is a crystalline silicon solar cell texturing auxiliary product. It is a water-soluble, non-toxic and harmless additive that meets environmental protection requirements. This product improves the etching selectivity ratio of inorganic alkali to silicon and forms a micron-level pyramid texture on the surface of the silicon wafer, thereby achieving a good light trapping effect.
JUNHE®2570 is a series of auxiliary additives independently developed by Junhe Technology for the removal of amorphous silicon from photovoltaic Topcon cells. It is a water-soluble, non-toxic and harmless additive that meets environmental protection requirements. This product can greatly improve the corrosion selectivity of inorganic alkali on the amorphous silicon coating of Topcon battery. While achieving silicon etching, it can also greatly reduce the corrosion of inorganic alkali on the positive film silicon dioxide layer or PSG layer.
JUNHE®2510-1 solar cell alkali polishing additive is suitable for alkali polishing of the backside of PERC solar cells and TopCon solar cell dewinding process. It is a water-soluble, non-toxic and harmless additive that meets environmental protection requirements. This product can greatly improve the corrosion selectivity ratio of inorganic alkali to silicon dioxide layer and silicon. While achieving polishing and etching of silicon, it can also greatly reduce the corrosion of inorganic alkali to silicon dioxide layer or PSG layer.
The Junhe Type-1017 products are single-component products which are compounded mainly with potassium salt, corrosion inhibitor, complexant, detergent and surfactant by polymerization. The reagent grade potassium hydroxide provides saponification alkalinity. The polymerization corrosion inhibitor, complexant, detergent and surfactant provide the cleaning. This product has a very good performance in emulsifying,saponification and cleaning the animal oil, vegetable oil, mineral oil, suspension and grinding paste. It has strong stripping,complexing and cleaning effect on the metal ions. The cleaning of oil is 99% as detection. The stripping,comlexing and cleaning effect to the copper,iron and other metal ions. Meanwhile, Junhe Type-1017 products does not contain the phosphate,calcium, magnesium, iron, copper, lead and other harmful silicon metal ions and meet the EU ROHS requirements with good environmental protection and strong cleaning ability.
This is patent products for degreasing electron level and solar grade silicon slice in IT and solar battery area, and the patent number is ZL200710020269.6. The product contain double group with good performance in emulsion saponifiation edulcoration to tallowvegetable oilmineral oilsoliquiodgrinding past , also in stripingcomplexing edulcoration to metal ion.
JH-2523Diamond Wire Cutting Fluid is a new type of product, it is mainly used for cutting process of all kinds of hard brittle materials(monocrystalline silicon, polycrystalline silicon, germanium, gallium arsenide, quartz, indium gallium nitride, gems, non-metallic materials, etc.), the features of excellent lubrication,coo ling,corrosion resistance,rust resistance and hydrogen inhibition function. The silicon surface TTV after cutting is small without wire mark and can prolong the life of diamond wire.
