Ukusetshenziswa Kwemikhiqizo
I-HQEE iyi-symmetrical aromamatic diol chain extender. Ingathuthukisa ukuqina, ukuqina, izakhiwo zokuqina kuma-MDI-polyurethane elastomers. I-HQEE/MDI iwuchungechunge lwe-PU elastomer oluhambisana ne-MOCA/TDI. Imikhiqizo eqediwe njengokuthi: izigxivizo zemithombo kawoyela, amathayi e-forklift, ibhande lokuthutha, izigxivizo ze-hydraulic cylinder seal neminye imikhiqizo eminingi ye-PU.
Ama-elastomer e-LCU adinga izingxenye ezimbili eziyinhloko: i-prepolymer enqanyulwe ngamaqembu e-isocyanate asebenzayo kanye ne-difunctional active hydrogen-terminated chain extender. I-Prepolymer iwumkhiqizo osuselwe ekuphenduleni kwe-polyester noma i-polyether ene-isocyanate (TDI, MDI, ADI). I-chain extender ngokuvamile iyiketango elifushane le-diamine noma i-diol. Ama-prepolymers e-MDI ngokuvamile anwetshwa ngama-diols.
Iphakheji Nesitoreji
Iphakheji:
25kg/ibhokisi lesigubhu noma njengezidingo zakho.
Phawula: Ukwakheka kwekhemikhali nosayizi kungenziwa ngokugcwele ngezidingo zamakhasimende
Isitoreji:
Gcina ivaliwe ngokuqinile. I-HQEE i-hygroscopic futhi izoshintsha umbala ngaphansi kokukhanya kwelanga. Gcina kuvaliwe futhi ugcine endaweni engenawo umoya. Gcina kude nomswakama nokukhanya kwelanga
Ukuvikela Ukuphepha
Izinyathelo zokuphepha zokuphatha okuphephile
Ukuphatha endaweni enomoya omuhle. Gqoka izingubo ezifanele zokuzivikela. Gwema ukuthinta isikhumba namehlo. Gwema ukwakheka kothuli nama-aerosol. Sebenzisa amathuluzi angashiyi izinhlansi. Vimbela umlilo obangelwa umusi wokukhipha i-electrostatic.
