Boron nitride is a most simple new kind of macromolecular resources with each of hexagonal and cubic crystal styles. It is a variety of item with high temperature-resisting, corrosion-resisting. Higher insulating and very good lubricity. Its oXiHu (West Lake) Dis.dation-resisting temperature can reach 1000 degree C, and possesses also good lubricity in substantial temperature, so it is a type of good high-temperature reliable lubricants. It has the quite EPTful capacity of neutron-absorbing. Its chemical properties are secure. It has very EPTful capability of neutron-absorbing, Its chemical qualities are stable, It has relatively very good corrosion-resisting capacity for different inorganic acids, alkali, salt remedies and natural and organic solvents. It existing chemical inert for practically each melting metals. Its resistance to large temperature can attain 2000 diploma C, and can reach 2800 diploma C when use it in nitrogen and argon. Its forming goods have the good residence simple to machining. Its humid resistance is really good. It has not only lower coefficient of warmth enlargement, but also warmth conductivity. It is each great heat conductor and typical electric powered insulator.
Boron nitride could be thoroughly utilized in the EPT departments of petroleum, chemical, EPTry, electronics, electrical EPT, textiles, nuclear, place and other. It could be utilised as the additives of such polymers as plastic resin and so on, the insulators of high strain high-frequency point and plasma are the reliable-section blended materials of semiconductor, the structural materials of atomic reactor, the EPT material for avoiding neutron radiation, the strong lubricant and dress in-resisting content and benzene absorbent etc. The combination of EPTium diboronide, EPTium nitride and boron oXiHu (West Lake) Dis.de, which is received by very hot-urgent forming of boron nitride and EPTium, is the catalyst for dehydrogenation of organic matters, rubber synthesis and platforming. In large temperature, it could be employed as the distinct resources of electrolysis and resistance, and very hot sealing dry -heating agent of transistor. It is the substance of aluminium evaporating container.
The boron nitride powEPTcould be also utilized as the stickiness-evidence agent for glass microbead, the demoulding agent for glass and metallic forming. The boron nitride manufactured overhard resources could be utilised for producing the substantial-pace chopping tool and the bit of geological prospecting and petroleum.
Boron nitride is physical inert. Its EPT is regarded as dangerous to XiHu (West Lake) Dis.Hu (West Lake) Dis.n. It will hurt one’s overall health by swallowing, inhaling, skin-connecting or eye-connecting. Swallowing and respiration will direct to unnormal to skin, respiratory system, liver, kidney and the circulatory technique. Pores and skin-making contact with or eye-getting in contact with will all give increase to stimulation. Need to use protection-protecting eyeglasses, dustproof gauze mask, rubber gloves throughout dealing with it.
It is vaccum-packed in aluminium foil bag, in which is place plastic bag. Web weigEPT 1kg a bag.
It should be stored in a shady, ventilating and dry storehouse. Its shelf life is one particular yr. The merchandise can be nonetheless utilised if up to stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd by means of retest right after the specified date.
