Zosungunulira Zamankhwala–Methylene Chloride Zopangidwa ku China

Chiyambi cha Zamalonda

Rich Chemical ndi kampani yaukadaulo yaku China yogulitsa dichloromethane ya mafakitale yopangidwa ku China, yomwe yakhala ikugwiritsidwa ntchito ndi mankhwala achilengedwe kwa zaka 10. Popereka chitsanzo chaulere, tikukulandirani mwansangala kuti mugule mankhwala apamwamba a CAS No. okhala ndi chiyero chapamwamba komanso mtengo wotsika ndi ife.

Tsatanetsatane wa malonda
Fomula ya maselo: CH2CL2
Kulemera kwa maselo: 84.93
Kapangidwe ka thupi ndi mankhwala: madzi osasunthika opanda mtundu, ofanana ndi fungo la ether ndi lokoma.
Kuchulukana kwa zinthu: D4201.326Kg/L.
kutentha kwa kutentha: 40.4 DEG C.
Malo osungunuka: -96.7 digiri, malo oyatsira moto ndi 615 DEG C. Amasungunuka pang'ono m'madzi, amasungunuka mu ethanol, ethyl ether, amawonjezera poizoni, mankhwala osokoneza bongo. Dichloromethane ndi madzi hydrolysis reaction, dichloromethane yokhala ndi stabilizer yogulitsa, kuti apewe hydrolysis. Dichloromethane ndi mpweya wambiri zimapangitsa kuti pakhale kusakaniza kophulika, koma sikuyaka, nthawi zambiri amagwiritsidwa ntchito m'makampani omwe ali ndi poizoni wochepa, zosungunulira zosayaka moto komanso malo owira otsika.

Cholinga
Pa zosungunulira zosayaka moto: kutsuka zitsulo, chochotsa utoto, chotsukira zitsulo, zosungunulira zitatu za cellulose acetate; filimu, aerosol, maantibayotiki ndi mavitamini popanga zosungunulira; chotsukira thovu popanga mapulasitiki aukadaulo; zinthu zoletsa moto; zomwe zimagwiritsidwa ntchito m'malo mwa F11 ndi F12 popanga zinthu; zinthu zopangidwa ndi mankhwala abwino.

Kulongedza, kusungira ndi kunyamula
Chitsulo chopangidwa ndi galvanized, ng'oma yakuda yachitsulo kapena chidebe chodzaza ndi thanki chokhala ndi dichloromethane, 80%, chingapereke chitetezo cha nayitrogeni kwa ogwiritsa ntchito omwe ali ndi zofunikira zapadera. Kusungirako kuyenera kusungidwa pamalo ozizira komanso ouma, nyumba yosungiramo zinthu iyenera kukhala ndi mpweya wokwanira kuti isakhudze mpweya wambiri kapena ma oxide, kuti isakhudze madzi kuti isakhudze madzi. Mayendedwe ayenera kutsatira zomwe Republic of China ikunena zokhudza kunyamula mankhwala oopsa kudzera m'misewu ikuluikulu ndi njanji.

Umoyo ndi chitetezo

Sichloromethane yomwe imaphulika mpweya: 8.1 ~ 17.2%, ndi ya mankhwala oyaka moto. Kuchuluka kwa mankhwalawa, kuwonekera nthawi yayitali kumayambitsa chizungulire, kugona tulo, nseru, kulira kwa tinnitus kapena dzanzi la miyendo, kusuntha kupita ku mpweya wabwino, zizindikirozo zimachira msanga, sizingayambitse kuwonongeka kosatha. Kuwaza m'maso kumayambitsa ululu ndi kukwiya, kukhudzana ndi khungu kwa nthawi yayitali kungayambitse dermatitis.
