Boron nitride is a most basic new type of macromolecular components with each of hexagonal and cubic crystal styles. It is a type of product with higher temperature-resisting, corrosion-resisting. Substantial insulating and very good lubricity. Its oXiHu (West Lake) Dis.dation-resisting temperature can attain a thousand diploma C, and possesses also great lubricity in higher temperature, so it is a variety of excellent large-temperature solid lubricants. It has the extremely EPTful capacity of neutron-absorbing. Its chemical homes are secure. It has really EPTful capacity of neutron-absorbing, Its chemical properties are steady, It has fairly good corrosion-resisting capability for different inorganic acids, alkali, salt answers and natural and organic solvents. It current chemical inert for practically every single melting metals. Its resistance to large temperature can get to 2000 degree C, and can attain 2800 degree C when use it in nitrogen and argon. Its forming items possess the fantastic home straightforward to machining. Its humid resistance is extremely great. It has not only minimal coefficient of heat growth, but also warmth conductivity. It is both excellent heat conductor and common electric insulator.
Boron nitride could be thoroughly utilised in the EPT departments of petroleum, chemical, EPTry, electronics, electric powered EPT, textiles, nuclear, space and other. It could be utilised as the additives of these kinds of polymers as plastic resin and so on, the insulators of substantial stress high-frequency position and plasma are the solid-section combined material of semiconductor, the structural content of atomic reactor, the EPT material for stopping neutron radiation, the reliable lubricant and dress in-resisting materials and benzene absorbent etc. The mixture of EPTium diboronide, EPTium nitride and boron oXiHu (West Lake) Dis.de, which is received by sizzling-pressing forming of boron nitride and EPTium, is the catalyst for dehydrogenation of organic issues, rubber synthesis and platforming. In high temperature, it could be used as the certain materials of electrolysis and resistance, and scorching sealing dry -heating agent of transistor. It is the substance of aluminium evaporating container.
The boron nitride powEPTcould be also utilised as the stickiness-proof agent for glass microbead, the demoulding agent for glass and metallic forming. The boron nitride made overhard materials could be employed for generating the large-velocity reducing device and the bit of geological prospecting and petroleum.
Boron nitride is physical inert. Its EPT is regarded harmful to XiHu (West Lake) Dis.Hu (West Lake) Dis.n. It will damage one’s health by swallowing, inhaling, skin-connecting or eye-connecting. Swallowing and breathing will guide to unnormal to pores and skin, respiratory program, liver, kidney and the circulatory system. Skin-contacting or eye-getting in contact with will all give increase to stimulation. Must use security-protective eyeglasses, dustproof gauze mask, rubber gloves during handling it.
It is vaccum-packed in aluminium foil bag, in which is place plastic bag. Net weigEPT 1kg a bag.
It need to be stored in a shady, ventilating and dry storehouse. Its shelf daily life is one particular yr. The item can be nonetheless utilized if up to stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd via retest after the specified date.
