Yini i-THFMA?

I-I-Tetrahydrofurfuryl methacrylate (THFMA)iwuketshezi olungenambala futhi olusobala olunamakhemikhali ahlukile futhi lusetshenziswa kabanzi emikhakheni eminingi yezimboni. Okokuqala, ekukhiqizeni irabha nepulasitiki, isebenza njenge-co-crosslinking agent kanye ne-modifier, engathuthukisa ngokuphumelelayo izakhiwo ezibonakalayo zenjoloba namapulasitiki, njengamandla, ukuqina nokuqina. Okwesibili, embonini yokugqoka, i-THFMA, njengesithuthukisi sokuhlanganisa, ingakwazi ukwandisa ngokuphawulekayo ukunamathela nokuqina kwezingubo futhi ithuthukise ikhwalithi nokusebenza kwezingubo.

Ukuqinisekisa ikhwalithi nokuphepha kwe-THFMA, izimo zayo zokugcina zibalulekile. Kunconywa ukuvala nokugcina i-THFMA endaweni epholile, eyomile ngaphansi kwezinga lokushisa elivamile nokucindezela, futhi ugweme ukuthintana nama-oxides nokukhanya ukuze kuvinjwe ukuthi ingawohloki noma ibangele izingozi zokuphepha. Ngaphezu kwalokho, ngenxa yokuthi i-THFMA iyavutha futhi iyacasula, ingase ibe nemiphumela emibi emehlweni, emgudwini wokuphefumula, nasesikhumbeni, ngakho-ke kufanele kusetshenziswe ukuqapha lapho uyisebenzisa.

Ngokombono wemvelo, i-THFMA iyingozi emizimbeni yamanzi, ngakho-ke kufanele ivinjwe ukuthi ingangeni phansi ukuze igweme ukungcolisa nokulimaza imithombo yamanzi okuphuza. Ukulungiswa kwe-THFMA kuvame ukuzuzwa nge-esterification noma ukusabela kwe-transesterification. Lezi zimo zokusabela zimnene futhi inqubo iyalawuleka, okuyindlela ephumelelayo yokuthola i-THFMA yekhwalithi ephezulu.

Ngenjwayelo,I-I-tetrahydrofurfuryl methacrylate (THFMA)iwukusetshenziswa kwamakhemikhali okuluhlaza okunamathemba abanzi okusebenza emikhakheni yezimboni efana nerabha, amapulasitiki, kanye nezingubo zokugqoka. Ngokugcina nokusetshenziswa okunengqondo, izinzuzo zayo zokusebenza zingasetshenziswa ngokugcwele kuyilapho kuqinisekiswa ukukhiqizwa okuphephile nokuvikelwa kwemvelo.
