I-HEMC yokunamathisela ithayela

I-HEMC, noma i-hydroxyethyl methyl cellulose, iyisithako esiyinhloko ekwakhiweni kokunamathela kwethayela. Kuyi-polymer encibilika emanzini esetshenziswa njenge-thickener, binder, ne-rheology modifier. I-HEMC isuselwa ku-cellulose futhi iyinhlanganisela engeyona i-ionic, engenabuthi, futhi engashi.

Ekwakhekeni kwe-adhesive tile, i-HEMC isetshenziswa ngokuyinhloko njenge-ejenti yokugcina amanzi. Ukwengezwa kwe-HEMC ekuxubeni kusiza ukuthuthukisa ukusebenza kwe-adhesive futhi kuvumela ukulawula okungcono kokuqukethwe kwamanzi. Lokhu kubalulekile ngoba okuqukethwe kwamanzi okunamathelayo kuthinta ukuvumelana kwayo, isikhathi sokumisa, namandla okugcina.

Enye yezinzuzo ezibalulekile ze-HEMC ekwakhiweni kwe-adhesive tile yikhono layo lokuthuthukisa ukunamathela kwe-adhesive kuma-substrates. I-HEMC isebenza njengesibophezelo, yenza isibopho esiqinile phakathi kwe-adhesive nendawo esetshenziswa kuyo. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho okunamathelayo kuzoba ngaphansi kwengcindezi ephezulu, njengokufakwa kwamathayili.

I-HEMC isiza futhi ukuvimbela ukuhlukaniswa kwezingxenye ezihlukahlukene ekwakhiweni kwe-adhesive tile. Lokhu kubalulekile ngoba i-adhesive exutshwe kahle iqinisekisa ukuthi izoba nezakhiwo ezingaguquki futhi izokwazi ukwenza njengoba kuhlosiwe.

Enye inzuzo ye-HEMC ekwakhekeni kwe-adhesive adhesive yikhono layo lokuthuthukisa ukumelana nokuncibilika kweqhwa. Lapho amanzi eba yiqhwa, ayanwebeka, okungabangela ukulimala kokunamathelayo. I-HEMC isiza ukuvimbela lokhu ngokwandisa ukunwebeka kwe-adhesive nokunciphisa inani lamanzi atholakalayo ukuqhwa.

I-HEMC iphinde ibambe iqhaza ku-rheology yokwakhiwa kwe-adhesive tile. I-Rheology yisifundo sokugeleza nokuguqulwa kwezinto. Ngokulungisa inani le-HEMC ekuxubeni, kungenzeka ukulawula izakhiwo ze-rheological ze-adhesive. Lokhu kungasetshenziswa ukudala ama-adhesive anezici ezithile, ezifana ne-viscosity ephezulu noma i-thixotropy.

Ngaphezu kwendima yayo ekwenziweni kwe-adhesive adhesive, 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 ekwakhekeni kwe-adhesive tile. Ikhono layo lokuthuthukisa ukusebenza, ukunamathela, ukumelana nokuncibilika kweqhwa, kanye nezakhiwo ze-rheological zokunamathisela kuyenza ibe yingxenye ebalulekile ezinhlelweni eziningi zokwakha, ikakhulukazi ekufakweni kwamathayili.
