Wogulitsa Wagolide Mankhwala Osakaniza DMC/Dimethyl Carbonate
Chiyambi cha Zamalonda
Dimethyl carbonate / DMC ndi chinthu chofunikira chachilengedwe chokhala ndi formula ya mankhwala C3H6O3 ndi kulemera kwa mamolekyulu a 90.08g/mol. Ndi madzi owonekera opanda mtundu, osasungunuka m'madzi, ndipo amasungunuka kwambiri mu zosungunulira zachilengedwe monga ethanol, benzene ndi acetone. Dimethyl carbonate ili ndi mawonekedwe a poizoni wochepa, kusasinthasintha kochepa, imatha kuwola bwino komanso yopanda vuto ku chilengedwe, kotero imagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, mankhwala, chakudya ndi zipangizo.

Kugwiritsa ntchito
1. Mu makampani opanga mankhwala, dimethyl carbonate imagwiritsidwa ntchito makamaka popanga polycarbonate yapamwamba kwambiri, polyurethane, aliphatic carbonate ndi zipangizo zina zofunika za polima.
2. Mu gawo la zamankhwala, dimethyl carbonate ndi mankhwala osungunuka achilengedwe otetezeka komanso ogwira mtima, omwe nthawi zambiri amagwiritsidwa ntchito popanga mankhwala, mankhwala oletsa ululu, magazi opangidwa ndi zinthu zina zamankhwala.
3. Mu makampani azakudya, monga chowonjezera chachilengedwe cha chakudya, dimethyl carbonate imagwiritsidwa ntchito kwambiri mu zokometsera, mkaka, zakumwa ndi zakudya zina kuti iwonjezere fungo ndi kukoma kwa chakudya.
Kuphatikiza apo, dimethyl carbonate ingagwiritsidwenso ntchito ngati chotsukira ndi chopangira surfactant, chomwe chimagwiritsidwa ntchito kwambiri m'magalimoto, ndege, zamagetsi, mankhwala, zokutira ndi mafakitale ena. Pomaliza, dimethyl carbonate ndi mankhwala achilengedwe omwe amagwira ntchito zambiri, otetezeka komanso oteteza chilengedwe, omwe amagwiritsidwa ntchito kwambiri m'magawo ambiri.
