Ibikoresho by'imiti bishongesha imiti–Methylene Chloride byakorewe mu Bushinwa

Intangiriro y'ibicuruzwa

Rich Chemical ni ikigo cy’umwuga cy’Ubushinwa gitanga dichloromethane yo mu rwego rw’inganda ikorerwa mu Bushinwa, imaze imyaka 10 ikora imiti y’umwimerere. Dutanga icyitegererezo cy’ubuntu, turakwemera cyane kugura imiti y’ubwoko bwa CAS No. nziza kandi ifite isuku nyinshi kandi ihendutse hamwe natwe.

Ibisobanuro birambuye ku gicuruzwa
Formule ya molekile: CH2CL2
Uburemere bwa molekile: 84.93
Imiterere y'umubiri n'iya shimi: amazi adafite ibara kandi abonerana, asa n'impumuro ya ether n'ibiryoshye.
Ubucucike bw'ibipimo: D4201.326Kg/L.
aho kubira: 40.4 DEG C.
Aho gushonga: -96.7 dogere, aho gushyushya ni 615 DEG C. Ishonga gato mu mazi, ishonga muri ethanol, ethyl ether, itera uburozi, itera ibiyobyabwenge. Dichloromethane na hydrolysis reaction y'amazi, dichloromethane irimo stabilizer yo mu bucuruzi, kugira ngo hirindwe hydrolysis. Dichloromethane na ogisijeni ifite ubwinshi bwinshi bizatanga uruvange ruturika, ariko ntirushobora gushya, ikoreshwa cyane mu nganda zifite uburozi buke, solvent idashya kandi ishyuha buhoro.

Intego
Ku kintu kidashya: gusukura icyuma, gukuraho irangi, ikintu gikuraho amavuta mu byuma, ikintu kigabanya amavuta mu byuma bitatu bya selulose acetate; firime, aerosol, antibiyotike na vitamine mu gukora ikintu kidashya; ikintu gitera ifuro mu gukora pulasitiki z'ubuhanga; ibintu bigabanya umuriro; bikoreshwa mu gusimbuza F11 na F12 mu gukora ibintu; ibikoresho byiza bya chimique.

Gupakira, kubika no gutwara
Icyuma cya galvanised, ingoma y'umukara cyangwa ikigega gipfunyitse gifite ingano ya dichloromethane, 80%, gishobora kurinda azote ku bakoresha bafite ibisabwa byihariye. Ububiko bugomba kubikwa ahantu hakonje kandi humutse, ububiko bugomba kuba bufite umwuka mwiza kugira ngo budahura n'umwuka mwinshi wa ogisijeni cyangwa ogisijeni, kugira ngo budahura n'amazi kugira ngo hirindwe ko amazi yagwa. Ubwikorezi bugomba kubahiriza amabwiriza ya Repubulika y'Ubushinwa yerekeye gutwara imiti ihumanya ikirere mu mihanda minini na gari ya moshi.

Ubuzima n'umutekano

Sichloromethane mu kirere ntarengwa cyo guturika: 8.1 ~ 17.2%, ni igikoresho gikoreshwa mu gutwika. Kwishyira hejuru cyane, igihe kirekire bitera kuzungera, gusinzira, isesemi, amenyo cyangwa gucika intege kw'ingingo, bijya mu mwuka mwiza, ibimenyetso bigaruka vuba, ntibizangiza ubuzima. Kwishyira mu maso bitera ububabare n'umujinya, gukora ku ruhu igihe kirekire bishobora gutera dermatitis.

Igipimo cy'ubuziranenge cya Q/0523 JLH002-2011 methylene chloride
