Izinamatheliso zamathayili ezisekelwe kusimende zisetshenziswa kakhulu emsebenzini wokwakha nokwakhiwa kwangaphakathi. Asetshenziselwa ukuvikela uthayela ezindongeni, phansi, nakwezinye izindawo. Lezi zinamathiselo ziqukethe isithako esibalulekile esizenza zisebenze kangcono: i-hydroxypropyl methylcellulose (HPMC).
I-HPMC iyi-polymer ye-cellulose eguquliwe enezinhlelo zokusebenza eziningi zezimboni. Kuma-adhesives we-tile, isetshenziswa njenge-thickener, i-ejenti yokugcina amanzi kanye ne-adhesive. Impushana emhlophe noma emhlophe, ayinabuthi, ayinaphunga futhi ayinambitheki.
Uma yengezwe kuma-adhesives asekelwe kusimende, ukusebenza kwayo kungathuthukiswa ngezindlela eziningi. Nazi ezinye izizathu zokuthi kungani i-HPMC iyisithako esibalulekile sokunamathela kuthayela kasimende:
1) Inikeza ukucutshungulwa okuthuthukisiwe
I-HPMC ithuthukisa ukusebenza ngokwenza okunamathelayo kukathayela kasimende kube lula ukukusebenzisa nokusabalalisa. I-HPMC inyusa i-viscosity ye-adhesive, iyenze ihlangane futhi kube lula ukusebenza nayo. Iphinde inciphise ukuwohloka, okuyilapho okunamathelayo kugijima noma kuconsa ukusuka phezulu.
2) Thuthukisa ukugcinwa kwamanzi
Izinamatheliso zamathayili e-Cementitious zilahlekelwa kalula umswakama ku-substrate esetshenziswa kuyo. I-HPMC isiza ukukhulisa ukugcinwa kwamanzi kwe-adhesive, okubalulekile ekwelapheni kahle kwe-adhesive. Lesi sici siqinisekisa ukuthi i-adhesive inokuphila ende futhi ingamelana nomswakama, ukushisa nezinye izakhi zemvelo. Lokhu kubaluleke kakhulu uma uthayela efakwe ezindaweni ezimanzi njengezindlu zangasese namakhishi.
3) Inonamathela kangcono
I-HPMC iyisinamathiselo esisebenzayo esithuthukisa ukusebenza kwesibopho sokunamathela kuthayela okusekelwe kusimende. Uma yengezwe ku-adhesive, isiza ukuhlanganisa usimende nezinye izingxenye ze-adhesive ndawonye, okwenze kube nempumelelo ekubambeni i-tile nezinye izinto ku-substrate.
4) Yehlisa imifantu
Ukuqhekeka kungenye yezinkinga ezivame kakhulu ngezinamatheliso zamathayela asekelwe kusimende. I-HPMC ingasiza ekunciphiseni ukuqhekeka ngokwandisa ukuguquguquka kwe-adhesive nokunciphisa ukushwabana. Lokhu kubaluleke kakhulu uma amathayela ebekwe phezu kwama-substrates akhiphekayo kalula njengendawo yokhuni noma yensimbi.
5) Thuthukisa ukuqina
I-HPMC ingathuthukisa ukuqina kwezinamatheliso zamathayela asekelwe kusimende. Ivimbela ukunamathela ekuqhekekeni ngenxa yokuchayeka kumswakama nezinye izici zemvelo. Iphinde inciphise inani le-efflorescence elakha phezu kwethayela.
6) Khulisa isivinini esibekiwe
I-HPMC isiza ukusheshisa ukumiswa kwezinamatheliso zamathayela asuselwa kusimende. Lokhu kubalulekile uma isikhathi sibalulekile futhi okunamathelayo kudinga ukusetha ngokushesha ukuze kugcinwe ithayela ngokuphephile.
I-7) Yehlisa ithuba lokuqhekeka kwe-grout
I-HPMC isiza ukunciphisa amathuba okuqhekeka kwe-grout. Ukuqhekeka kwe-grout kwenzeka lapho ukunyakaza kwe-substrate kuphula isibopho phakathi kwethayili ne-adhesive. I-HPMC ingenza okunamathelayo kunwebeka kakhulu, okusiza ukumunca ukunyakaza kwe-substrate futhi kuvimbele ukuqhekeka kwe-grout ukuthi akheke.
Kafushane, i-HPMC iyingxenye ebalulekile yezinamatheliso zamathayili asekelwe kusimende. Izakhiwo zayo ezinemisebenzi eminingi ziyenza ibe yingxenye ebalulekile yanoma iyiphi ingcina esetshenziselwa ukubeka amathayili. Idlala indima ebalulekile ukuqina, ukusebenza kanye nokunamathela kokunamathela. Uma ingezwe kumathayela asekelwe kusimende, iqinisekisa ukusebenza kahle, ukuphila isikhathi eside nokwaneliseka kwamakhasimende.
