Cristobalite is made of selected gangue quartz ore calcined at 1500℃ at high temperature, processed by pure grinding, magnetically separated and graded, with stable properties.The silicon content is more than 99.8 percent, the crystal phase is square crystal system, the hardness is about 6.5, the density is 2.45, bigger than the surface, high porosity, good weather resistance, good precipitation resistance, good thermal shock resistance.
Application scope :
Applied in jewelry casting, fine casting, dental materials, electronic chip polishing, polishing materials, building internal and external wall coating, road reflective coating, automotive primer, plastics, rubber, silicone rubber, adhesive, national defense and other fields
Application of cristobalite in adhesive
Cristobalite oil absorption value is low, basic no edges and corners, viscosity is relatively low white carbon black, weatherability than silica (white carbon black for alkaline), good bonding effect (surface) between cristobalite, good peel strength, pulled off high strength, high surface resistance and can be modified with epoxy resin and other resin system better, to eliminate air bubbles and settlement.Appropriate proportion of diatomite can be added in the formulation process to better improve the adhesion.
Silicon powder joint surface, has obvious edges and corners, not easy to bond.Kaolin is hexagonal, red after burning, and joint (not easy to stick).
Lianyungang changtong strong force, with advanced processing equipment, the use of advanced impurity removal, purification process, is a collection of development, production and sales as one of the manufacturers, more multi quartz details welcome your consultation.
