Umthelela Obalulekile we-"Thickener" ekusebenzeni kwe-Cellulose Ether ku-Mortars

I-Cellulose ether iyisengezo esisetshenziswa kakhulu odakeni, okuwuhlobo lwempahla yokwakha esetshenziswa ekwakheni. Isetshenziselwa ukuthuthukisa izakhiwo zodaka, okuhlanganisa ukusebenza kwayo, ukunamathela, nokuqina. Isici esisodwa esibalulekile esithinta ukusebenza kwe-cellulose ether kuma-mortars ukukhethwa kwe-thickener. Kulesi sihloko, sizoxoxa ngethonya elibalulekile le-thickener ekusebenzeni kwe-cellulose ether kuma-mortars.

I-Thickener iwuhlobo lwesithasiselo esisetshenziselwa ukwandisa i-viscosity yoketshezi. Ivamise ukungezwa ku-cellulose ether odakeni ukuze kuthuthukiswe ukusebenza kwayo. Ukukhethwa kwe-thickener kungaba nomthelela omkhulu ezimpahleni zodaka, okuhlanganisa ukusebenza kwawo, ukugcinwa kwamanzi, nokumelana nokucwila.

Enye yezinto ezijiya kakhulu ezisetshenziswa kakhulu odakeni lwe-cellulose ether i-hydroxyethyl cellulose (HEC). I-HEC iyi-polymer encibilika emanzini eyaziwa ngokujiya kwayo okuhle kakhulu nokugcina amanzi. Kuyaziwa nangokuthi ikhono layo lokuthuthukisa ukusebenza kodaka, okwenza kube lula ukuyifaka nokuma.

Esinye isici esivame ukusetshenziswa emazingeni e-cellulose ether i-methyl cellulose (MC). I-MC iyi-polymer encibilika emanzini eyaziwa ngokujiya kwayo okuhle kakhulu kanye nezindawo zokugcina amanzi. Yaziwa futhi ngamandla ayo okuthuthukisa ukumelana nokuntenga kodaka, okusiza ukuyivimbela ukuthi ingasheleli noma iwele endaweni eqondile.

Ukukhethwa kwe-thickener nakho kungathinta isikhathi sokubeka udaka. Amanye ama-thickeners, afana ne-MC, angasheshisa isikhathi sokusetha sodaka, kanti amanye, njenge-HEC, angayinciphisa. Lokhu kungase kube ukucatshangelwa okubalulekile emisebenzini yokwakha lapho isikhathi sokumisa sidinga ukulawulwa ngokucophelela.

Inani le-thickener elisetshenzisiwe lingaba nomthelela ezinhlelweni zodaka. Ukujiya kakhulu kungenza udaka lubonakale kakhulu futhi kube nzima ukusebenza ngalo, kuyilapho ukujiya okuncane kakhulu kungabangela udaka oluncane kakhulu futhi olujwayele ukucwila noma ukuwohloka.

Ngaphezu kwe-HEC ne-MC, kunezinye izingqimba eziningana ezingasetshenziswa osikeni lwe-cellulose ether, okuhlanganisa i-carboxymethyl cellulose (CMC) ne-hydroxypropyl methyl cellulose (HPMC). I-thickener ngayinye inezici zayo eziyingqayizivele futhi ingasetshenziswa ukufeza izici ezithile zokusebenza odakeni.

Kafushane, ukukhethwa kwe-thickener kungaba nomthelela omkhulu ekusebenzeni kwe-cellulose ether kuma-mortars. Izakhiwo ze-thickener, okuhlanganisa ikhono layo lokujiya, ukugcinwa kwamanzi, ukumelana nokucwila, kanye nomthelela ngesikhathi sokusetha, kufanele kucatshangelwe ngokucophelela lapho kukhethwa ukuqina okuzosetshenziswa odakeni. Ngokukhetha i-thickener efanele futhi bayisebenzise ngenani elifanele, abakhi nochwepheshe bezokwakha bangaqinisekisa ukuthi udaka lwabo lusebenza kahle futhi luhlangabezana nezidingo eziqondile zephrojekthi yabo yokwakha.
