-Molecular qauv

 

Cov mis mos molecular: HLO 2

Molecular hnyavib: 45.041

Cov khoom: tsis muaj xim thiab pob tshab kua, me ntsis ammonia.Melting point 2.55 ℃, Boiling point 210-212 ℃ (ib nrab decomposed ntawm 180 ℃), Flash point 154 ℃, tshwj xeeb gravity 1.1334 (20 ℃).Hygroscopic, miscible nrog dej thiab ethanol, me ntsis soluble hauv benzene, chloroform thiab ether.

Siv: raw khoom ntawm Synthetic tshuaj, txuj lom, dyes thiab lwm yam, kuj yog ib tug hnyav rau spinning ntawm hluavtaws fibers, yas ua, zus tau tej cov ntoo casein number case.Kuj tseem siv los ua daim ntawv ua tus neeg sawv cev, coagulant ntawm cov roj drilling thiab kev tsim kho kev lag luam, carburizing nitriding tus neeg sawv cev hauv kev lag luam foundry, tsiaj kua nplaum softener thiab polar hnyav ntawm cov organic synthesis.

Ntim, cia thiab tsheb thauj mus los: 220L yas nruas los yog steel-yas composite chim.Lub hau yuav tsum raug kaw kom tsis txhob muaj dej thiab tsis txhob sib cuag nrog dej.Khaws rau hauv qhov chaw txias, qhuav, deb ntawm qhov hluav taws kub thiab cua sov.
