I-HEMC FOR Dry Mix Mortars

I-HEMC, noma i-hydroxyethyl methyl cellulose, iyisithako esiyinhloko osikeni lwengxube eyomile.Kuyi-polymer encibilika emanzini esetshenziswa njenge-ejenti yokuqina, i-binder, ne-rheology modifier.I-HEMC isuselwa ku-cellulose futhi iyinhlanganisela engeyona i-ionic, engenabuthi, futhi engashi.

Emasikeni okuxuba okomile, i-HEMC isetshenziswa ngokuyinhloko njenge-ejenti yokugcina amanzi.Ukwengezwa kwe-HEMC ekuxubeni kusiza ukuthuthukisa ukusebenza kodaka futhi kuvumela ukulawula okungcono kokuqukethwe kwamanzi.Lokhu kubalulekile ngoba okuqukethwe kwamanzi odaka kuthinta ukuvumelana kwawo, isikhathi sokumisa, namandla okugcina.

Enye yezinzuzo eziyinhloko ze-HEMC ku-dry mix mortars yikhono layo lokuthuthukisa ukunamathela kodaka kuma-substrates.I-HEMC isebenza njengesibopho, idala isibopho esiqinile phakathi kodaka nendawo esetshenziswa kuyo.Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho udaka luzoba ngaphansi kwengcindezi ephezulu, njengokufakwa kwamathayili.

I-HEMC isiza futhi ukuvimbela ukuhlukaniswa kwezingxenye ezihlukahlukene kudaka lokuxuba okomile.Lokhu kubalulekile ngoba udaka oluxutshwe kahle luqinisekisa ukuthi luzoba nezakhiwo ezingaguquki futhi luzokwazi ukwenza njengoba kuhlosiwe.

Enye inzuzo ye-HEMC ku-dry mix mortars yikhono layo lokuthuthukisa ukumelana neqhwa lokuncibilika kodaka.Uma amanzi eba yiqhwa, ayanwebeka, okungadala umonakalo odakeni.I-HEMC isiza ukuvimbela lokhu ngokwandisa ukunwebeka kodaka kanye nokunciphisa inani lamanzi atholakalayo ukuze abe yiqhwa.

I-HEMC iphinde ibambe iqhaza ku-rheology yezigxobo zokuxuba ezomile.I-Rheology yisifundo sokugeleza nokuguqulwa kwezinto.Ngokulungisa inani le-HEMC ekuxubeni, kungenzeka ukulawula izakhiwo ze-rheological zodaka.Lokhu kungasetshenziswa ukudala udaka olunezici ezithile, ezifana ne-viscosity ephezulu noma i-thixotropy.

Ngaphezu kwendima yayo emigodini yokuxuba okomile, i-HEMC iphinde isetshenziswe kwezinye izinhlelo zokusebenza ezihlukahlukene.Ivamise ukusetshenziswa njenge-thickener kanye ne-stabilizer emikhiqizweni yokudla, kanye nasemikhiqizweni yokunakekelwa komuntu siqu njengama-shampoos nama-lotions.I-HEMC iphinde isetshenziswe njenge-thickener kanye ne-binder ekukhiqizeni amapende e-latex.

Sekukonke, i-HEMC iyisithako esibalulekile odakeni lwengxube eyomile.Ikhono layo lokuthuthukisa ukusebenza, ukunamathela, ukumelana nokuncibilika kweqhwa, kanye nezakhiwo ze-rheological zodaka kuyenza ibe yingxenye ebalulekile ezinhlelweni eziningi zokwakha.
