I-Polyurethane eshaya i-ejenti mofan ml90
UMofa ML90 uyi-methylal evuthayo enokuqukethwe okungaphezulu kwama-99,5%, kuyinto ejenti yezemvelo nangokomnotho evuthayo ukusebenza kahle kwezobuchwepheshe. Kuhlanganiswe nama-polyols, ama-flammus awo angalawulwa. Ingasetshenziswa njenge-ejenti evuthayo kuphela ekwakhekeni, kepha futhi kuletha izinzuzo ngokuhambisana nabo bonke abanye abashayeli be-blowing.
Ukuhlanzeka okungekho emthethweni nokusebenza
UMofa ML90 uvelele emakethe ngenxa yokuhlanzeka kwayo okungenakuqhathaniswa. Le methylal ephuthumekayo akuyona nje umkhiqizo; Kuyisixazululo esenzelwe abakhiqizi ababeka phambili ikhwalithi nokusimama. Ubumsulwa obuphakeme be-mofan ML90 buqinisekisa ukuthi lihlangabezana nezidingo eziqinile zezinhlelo zokusebenza ezahlukahlukene ze-foam, zinikeza imiphumela engaguquki futhi zithuthukise ikhwalithi ephelele yomkhiqizo wokugcina.
I-ejenti yemvelo nangokomnotho evuthayo
Njengoba izimboni zilwela ukunciphisa izinyathelo zazo zemvelo, ama-mofan ml90 aqhamuka njengokukhethwa kwemvelo nangokomnotho. Ukwakheka kwayo kuvumela ukulawulwa okusebenzayo kokuvuselelwayo lapho kuhlanganiswa ngama-polyols, okwenza kube inketho ephephile yezinhlobonhlobo zezicelo. Lokhu kuguqulwa okuguquguqukayo kusho ukuthi i-mofan ml90 ingasetshenziswa njenge-ejenti yokuqhuma nje ekwakhiweni noma ngokuhlanganiswa namanye ama-ejenti ashayelwa, enikeza abakhiqizi ukuguquguquka okudingayo ukuze basebenzise izinqubo zabo.
● Akunakuvutha kancane kune-n-pentane ne-isopentane evuthayo kakhulu. Inhlanganisela yama-polyols anesamba esisebenzayo se-methylal ye-polyurethane Foams show high flash point.
● Inephrofayili enhle ye-ecotoxicological.
● I-GWP ingama-3/5 kuphela we-GWP wamaPentanes.
● Ngeke i-hydrolyze ngonyaka o-1 ezingeni le-PH ngenhla kwama-polyols ahlanganisiwe.
● Kungakungazeki ngokugcwele ngawo wonke ama-polyols, kufaka phakathi ama-polyol aphungelayo e-polyester polyols.
● Kuyinto yokubona okuqinile. Ukuncishiswa kuncike ekubonakaleni kwe-polyol uqobo: okuphezuluI-viscosity, kukhuphuka ukuncipha.
● Ukusebenza kwamagwebu okungeziwe kwe-1 wt okungeziwe kulingana ne-1.7 ~ 1.9WT HCFC-141B.

Izindlela zokuqapha ngokuphephile
Iseluleko ngokuvikelwa komlilo nokuqhuma
"Gcina kude namalangabi avulekile, izindawo ezishisayo nemithombo yokulahla.Thatha ukuphepha
izinyathelo ngokumelene nokukhishwa kwe-tuli. "
Izindlela zokuhlanzeka
Shintsha izingubo ezingcolile. Geza izandla ngemuva kokusebenza ngento.
Izimo zesitoreji esiphephile, kufaka phakathi noma yikuphi ukungahambisani
"Gcina isitsha sivalwe ngokuqinile endaweni eyomile futhi enomoya omuhle. Gcina kude nokushisa futhiimithombo yokulahla. "
