Zirconia Ceramic Dispensing Valve Precision Accessories
Mingrui ceramics specialized in researching and development, the traditional dispensing valve mainly adopts metal
materials, but not environmental protection, wear-resistance, there are a lot of insufficient place, Zirconia Ceramic
Dispensing Valve with wear resistance, superstrong, superhard, high temperature, refractorily, super corrosion resistance,
never rust, oxidation resistance, insulation, self-lubrication and other excellent performance. Other similar valves, such as
ceramics flush valve and ZrO2 fluid dispensing valve.
Ceramic dispensing valve commonly used in the common UV glue, silicon, EPOXY, silver glue, AB glue, red glue, COB black
glue, conductive adhesive, thermal aluminum paste, instant glue, hot melt adhesive using industry: optics, photoelectric industry
biochemical industry photovoltaic solar industry SMD/SMT SMT semiconductor manufacturing industry, pharmaceutical industry,
LCD/LED, laboratory, electronic industry, semiconductor packaging PCB fixed and protect LCD glass machine board electronic
components encapsulation adhesive mobile telephone plate coated or key point glue dispensing speaker battery box coating glue
sealing steam car machinery parts, hardware parts coating and then etc
The products are made of high purity zirconia ceramic and alumina ceramic material, which have
advanced and excellent performances, fabulously popular .
