China Transparent no Pb low melting point glass powder for welding flux

Transparent no Pb low melting point glass powder for welding flux
Product Description
Low melting point glass powder is an advanced sealing material, the material has a lower melting temperature and sealing temperature, Good heat resistance and chemical stability, high mechanical strength. Is widely used in vacuum and microelectronics, laser and infrared technology, high energy physics, energy, aerospace, automotive and many other fields. Can achieve glass, ceramics, metals, semiconductor mutual sealing. Low-melting glass powder as a new type of material, has been applied to some new materials, but the application prospects far beyond the current encounter, but also to the field of materials professionals to explore and expand.
Low melting point glass powder product advantages:
1.Stable quality, different melting temperature optional, more applicability.
2.Has excellent physical and chemical properties: transparent, white, ultra-pure and grain average, lower melting temperature and sealing temperature, good heat resistance and chemical stability.
3.New sealing material, Cost-effective.
4.Special materials, strong technical support, expert technical team, can jointly develop new materials related.
The difference between Low melting glass powder and ordinary glass powder:
Low temperature melting glass powder, namely low melting point glass powder. The production of raw materials and glass powder different ,functional role is superior to the glass powder. Low temperature melting glass powder should be distinguished from the glass powder.Low-temperature melting glass powder for the use of relatively environmentally friendly materials by mixing, in the high temperature environment melting copolymerization to produce silicon borosilicate metal salts, with the characteristics of ultra-low temperature melting (usually 390-780 ℃). In the market, the usual glass powder is amorphous inorganic particles. The raw materials used for the production are heavy metal substances such as PbO and the like, and undergo solid-state reaction at high temperature to form glass homogenates with disorder structure.
Product ParameterProduct ingredient description:Low-melting glass powder is made of natural high-purity non-metallic minerals: kaolin, limestone, wollastonite, silica, nepheline, potassium feldspar, albite, boron salts and green flux materials, After crushing, high-purity water treatment, drying, air mill, wind election and other multi-channel process from the functional powder.Density: 2.28g / cm3 Mohs hardness: 6.2 Melting point: 390 ℃ ~ 700 ℃

In high temperature coatings, paints and inks using the product:
High-temperature coatings, paints and inks, and conventional coatings, paints and inks are not significantly affected by processes or methods such as spraying, brushing, roller coating, screen printing and roll printing after the coated / painted / printed workpieces have been completely pretreated Difference; only in the curing methods and methods are different, the traditional coatings, paints and inks are used at room temperature self-crosslinking / reaction curing, heating to 60 ~ 180 degrees C curing and AB two-component reaction curing; Paint, paint and ink products need to absorb enough heat and a certain melting process can be achieved, usually using a tunnel furnace, the process temperature is set at 480 to 700 degrees Celsius melting after curing.
Low-temperature melting glass powder in high temperature coatings, paints and inks products application, should be designed by the laboratory test small recipe and process through a small test. Large production in strict accordance with the established formula and process fine-tuning implementation. Two kinds of water-dispersible system and oily system under large-scale formula design are added by first adding water or solvent, then dropping into low-temperature molten glass powder, pigment, anti-settling agent and a very small amount of low-carbon high-viscosity resin, The resulting product (if necessary with multi-roller equipment or sanding equipment to produce better).
