Product Description

Features

Our company sells the nitrided silica flour body purity is high, the particle size is small, the distribution is even, is bigger than the surface area, the surface activity is high, the pine installs the density to be low, the ultraviolet ray index of reflection is above 95% and the absorption infrared wave band absorption rate above 97%, component's Cheng Ci the temperature is low, the size stability is good, the mechanical strength is high, bears the chemical etching performance to be good, the high temperature intensity is specially big, and has the self lubrication effect, it forms the slight dispersed phase in the compound materials, thus enhanced the compound materials overall performance greatly. Its product itself has the self lubrication performance, may apply in the lubricating oil. Silicon nitride degree of hardness is high, the sliding friction coefficient small characteristic may apply wear-resisting in the metal surface ceramics compound plates, applies in the coating to be possible to get up with bears the resolver characteristic wear-resisting.

Application 

1.manufacture structure component: Like professions and so on metallurgy, chemical industry, machinery, aviation, astronautics and energy uses rolling bearing's ball bearing and the roller, the sliding bearing, the wrap, the valve as well as have wear-resisting, thermostable, the anti-corrosive request structure component, the rocket with the spray nozzle, the missile use the nozzle;

2.metals and other material surface treatments: Like mold, cutting tool, steam turbine leaf blade, turbine rotor as well as alloy and so on cylinder endophragm coating;

3.compound materials: Like metal, ceramic and graphite base compound materials, rubber, revertex, coating, adhesive and other high score subbasis compound materials;

4.wear-resisting self lubrication nano particles thin film, uses in surface protections and so on handset, high-quality automobile, the wear-resisting coating, the electrophoretic paint chemical additive, have the high wear-resisting characteristic.

Storage conditions

Damp reunion will affect its dispersion performance and using effects, therefore, this product should be sealed in vacuum and stored in cool and dry room and it should not be exposure to air. In addition, the product should be avoided under stress.
