-Molecular qauv qauv
Molecular Cov Qauv: Hconh2
Molecular hnyav: 45.0411
Cov Khoom Siv: tsis muaj xim thiab pob tshab kua, ammonia me ntsis. Melting taw tes 2.55 ℃, boiling point 210-212 ℃ (ib nrab decomposed ntawm 180 ℃), nyem taw tes [1334 (20 ℃). Hygroscopic, tsis pub twg nrog dej thiab ethanol, me ntsis soluble hauv benzene, chloroform thiab ether.
Siv: Cov khoom siv raw ntawm cov tshuaj hluavtaws, cov txuj lom, ua kom muaj zog thiab lwm tus, kuj yog cov kuab tshuaj ntawm hluavtaws fibers, kev ua lag luam yas, kev tsim khoom ntawm rooj ntoo rooj noj mov. Kuj tseem siv los ua tus neeg sawv cev ntawv, sib koom ua ke roj drilling thiab kev tsim kho kev lag luam, tsiaj carburizing tus neeg sawv cev hauv kev lag luam organic ntawm cov organic synthesis.
Ntim, cia thiab tsheb thauj mus los: 220l yas nruas lossis steel-yas composite chim. Lub hau yuav tsum raug kaw kom tiv thaiv kom tsis txhob to feakage thiab zam kom tsis txhob sib cuag nrog dej. Khaws cia rau hauv qhov chaw txias, qhuav, deb ntawm qhov hluav taws kub thiab kub.
