I-BG-2655-100

I-ejenti yokwelapha emanzini-BG-2655-100

Incazelo emfushane:

I-BG-2655-100 iyi-ejenti yokwelapha ye-isocyanate ehlakazeka emanzini esekelwe ku-hexamethylene diisocyanate, esetshenziswa ngokuhambisana ne-polyurethane ephuma emanzini, i-polyacrylate, enokumelana okuhle kakhulu kwe-hydrolysis nokumelana nokushisa.

Ukugqoka okulungiselelwe okusekelwe emanzini okunezingxenye ezimbili kunezici zokucwebezela okuphezulu, ukugcwala okuphezulu, ukuqina okuphezulu, ukumelana nokuphuzi okuhle kakhulu, nokumelana okuhle kwamakhemikhali.

Imininingwane

Ukubukeka Uketshezi olubonisa ngale olumhlophe ukuya kokuphuzi kancane
Okuqukethwe okungaguquguquki (%) 98-100
I-Viscosity (mPa • s/25 ℃) 1500 ~ 4500
I-HDI monomer yamahhala (%) ≤0.5
Okuqukethwe kwe-NCO (nikeza %) 19.0~21.0

Iziyalezo

Lapho i-BG-2655-100 ihlakazeka, i-viscosity yayo izokhula. Uma ixutshwe ne-hydrophilic polyol dispersions, ingahlanjululwa ngamanzi kusengaphambili noma inani elincane le-solvent lingangezwa ukulawula ukwanda kwe-viscosity, njenge-propylene glycol methyl ether acetate (PMA), i-propylene glycol diacetate (PGDA), futhi Kunconywa ukusebenzisa izinyibilikisi zezinga le-polyurethane (okuqukethwe kwamanzi<0.05%) ukuze kuhlanjululwe, ngokuqukethwe okuqinile okungengaphansi kwama-40%. Yenza izivivinyo ezithile kanye nokuhlola ukuzinza ngaphambi kokusetshenziswa. Uma ingxube emva kokungeza BG-2655-100, kufanele isetshenziswe ngaphakathiimpilo yebhodwe.

isitoreji

Umkhiqizo kufanele ugcinwe esitsheni esivaliwe ukuze ugweme ukuqhwa kanye nokushisa okuphezulu. Kunconywa ukugcina iphakheji evaliwe iqinile endaweni yokushisa engu-5-35 ℃. Impilo yeshelufu yomkhiqizo yizinyanga eziyishumi nambili kusukela ngosuku lokukhiqiza. Ngemuva kokuthi isikhathi seshelufu sesidlulile, kunconywa ukwenza ukuhlolwa kokusebenza ngaphambi kokusetshenziswa.

Umkhiqizo uzwela kakhulu kumswakama futhi uhlangana namanzi ukukhiqiza amagesi afana ne-carbon dioxide ne-urea, okungabangela ukucindezela kwesitsha ukuthi kukhuphuke futhi kube yingozi. Ngemuva kokuvula ukupakisha, kunconywa ukuthi uyisebenzise ngokushesha ngangokunokwenzeka.
