Boron nitride is a most simple new variety of macromolecular supplies with equally of hexagonal and cubic crystal styles. It is a type of solution with large temperature-resisting, corrosion-resisting. High insulating and very good lubricity. Its oXiHu (West Lake) Dis.dation-resisting temperature can get to 1000 degree C, and possesses also excellent lubricity in higher temperature, so it is a variety of great high-temperature strong lubricants. It has the extremely EPTful capacity of neutron-absorbing. Its chemical qualities are stable. It has extremely EPTful capacity of neutron-absorbing, Its chemical homes are secure, It has reasonably excellent corrosion-resisting capacity for a variety of inorganic acids, alkali, salt remedies and natural and organic solvents. It present chemical inert for almost every single melting metals. Its resistance to high temperature can achieve 2000 degree C, and can attain 2800 diploma C when use it in nitrogen and argon. Its forming products possess the fantastic residence straightforward to machining. Its humid resistance is quite great. It has not only low coefficient of heat enlargement, but also heat conductivity. It is each excellent heat conductor and standard electric insulator.
Makes use of:
Boron nitride could be thoroughly utilized in the EPT departments of petroleum, chemical, EPTry, electronics, electric powered EPT, textiles, nuclear, room and other. It could be utilized as the additives of such polymers as plastic resin and so on, the insulators of higher strain higher-frequency stage and plasma are the strong-section combined materials of semiconductor, the structural substance of atomic reactor, the EPT substance for protecting against neutron radiation, the reliable lubricant and use-resisting materials and benzene absorbent and so on. The mixture of EPTium diboronide, EPTium nitride and boron oXiHu (West Lake) Dis.de, which is received by hot-urgent forming of boron nitride and EPTium, is the catalyst for dehydrogenation of natural and organic issues, rubber synthesis and platforming. In high temperature, it could be used as the distinct 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 employed as the stickiness-proof agent for glass microbead, the demoulding agent for glass and metal forming. The boron nitride made overhard resources could be utilized for creating the higher-pace reducing tool and the bit of geological prospecting and petroleum.
Boron nitride is physical inert. Its EPT is regarded as harmful to XiHu (West Lake) Dis.Hu (West Lake) Dis.n. It will harm one’s overall health by swallowing, inhaling, skin-connecting or eye-connecting. Swallowing and breathing will lead to unnormal to pores and skin, respiratory program, liver, kidney and the circulatory program. Pores and skin-getting in touch with or eye-making contact with will all give rise to stimulation. Need to wear security-protecting eyeglasses, dustproof gauze mask, rubber gloves for the duration of managing it.
It is vaccum-packed in aluminium foil bag, in which is put plastic bag. Internet weigEPT 1kg a bag.
It must be saved in a shady, ventilating and dry storehouse. Its shelf lifestyle is a single 12 months. The merchandise can be still employed if up to stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd through retest after the specified date.
