Izinamathiselo zamathayela zidlala indima ebalulekile embonini yezokwakha, ziqinisekisa ukubopha okuphephile kwamathayela kuma-substrates ahlukahlukene.IHydroxypropyl Methylcellulose (HPMC) iyisithako esiyinhloko ezintweni eziningi zokunamathisela zamathayela zanamuhla, ezinikeza izici zokunamathela ezithuthukisiwe nokusebenza kahle.
1.Ukuqonda i-Hydroxypropyl Methylcellulose (HPMC):
I-HPMC iphuma ku-cellulose evamise ukusetshenziswa ezintweni zokwakha ngenxa yokunamathela kwayo, ukujiya, kanye nezindawo zokugcina amanzi.
Itholakala ku-cellulose yemvelo futhi icutshungulwe ibe yimpushana enhle.
I-HPMC ithuthukisa amandla okubopha okunamathelayo kwamathayela kuyilapho ithuthukisa ukusebenza kwazo nezici zokugcinwa kwamanzi.
2.Ukwakhiwa kwe-HPMC-based Tile Adhesive:
a.Izithako Eziyisisekelo:
I-Portland Cement: Ihlinzeka nge-ejenti ebophayo eyinhloko.
Isihlabathi esihle noma isigcwalisi: Sithuthukisa ukusebenza futhi sinciphise ukushwabana.
Amanzi: Ayadingeka ukuze kufakwe amanzi kanye nokusebenza kahle.
IHydroxypropyl Methylcellulose (HPMC): Isebenza njenge-ejenti ejiya futhi ebophayo.
Izengezo: Kungase kuhlanganise izilungisi ze-polymer, izisabalalisi, nama-anti-sag agents ezithuthukisweni ezithile zokusebenza.
b.Ukulinganisa:
Ingxenye yesithako ngasinye iyahlukahluka kuye ngezinto ezifana nohlobo lwethayela, i-substrate, nezimo zemvelo.
Ukwakheka okujwayelekile kungase kuhlanganise usimende ongu-20-30%, isihlabathi esingu-50-60%, u-0.5-2% we-HPMC, kanye nokuqukethwe kwamanzi okufanele ukuze kuzuzwe ukuvumelana okufunayo.
c.Inqubo Yokuxuba:
Yomisa hlanganisa usimende, isihlabathi, kanye ne-HPMC kahle ukuze uqinisekise ukusatshalaliswa okufanayo.
Yengeza kancane kancane amanzi ngenkathi uhlanganisa kuze kube yilapho kutholakala ukuvumelana okufunayo.
Xuba kuze kutholakale inhlama ebushelelezi, engenazigaxa, uqinisekise ukugeleza okufanele kwezinhlayiya zikasimende nokuhlakazwa kwe-HPMC.
3.Ukusetshenziswa kwe-HPMC-Based Tile Adhesive:
a.Ukulungiswa kwendawo:
Qinisekisa ukuthi i-substrate ihlanzekile, iphilile, futhi ayinalo uthuli, amafutha kanye nokungcola.
Izindawo ezimahhadlahhadla noma ezingalingani zingadinga ukuleveliswa noma ukulungiswa ngaphambi kokufaka ingcina.
b.Amasu ohlelo lokusebenza:
Ukusetshenziswa kweTrowel: Indlela ejwayeleke kakhulu ihlanganisa ukusebenzisa i-notched trowel ukusabalalisa okunamathelayo ku-substrate.
I-back-buttering: Ukufaka ungqimba oluncane lwe-adhesive ngemuva kwama-tile ngaphambi kokuwabeka embhedeni wokunamathisela kungathuthukisa ukubopha, ikakhulukazi kumathayela amakhulu noma asindayo.
I-Spot Bonding: Ifanele amathayela angasindi noma izinhlelo zokusebenza zokuhlobisa, kuhlanganisa ukusebenzisa ingcina ngeziqephu ezincane kunokuyisakaza kuyo yonke i-substrate.
c.Ukufakwa Kwethayela:
Cindezela amathayela ngokuqinile embhedeni wokunamathisela, uqinisekise ukuthintana okugcwele kanye nokumbozwa okufanayo.
Sebenzisa ama-spacers ukugcina amalunga e-grout angaguquki.
Lungisa ukuqondanisa kwethayili ngokushesha ngaphambi kokuba okunamathelayo kusethwe.
d.Ukwelashwa nokuvimbela:
Vumela okunamathelayo ukuthi kwelaphe ngokweziqondiso zomkhiqizi ngaphambi kokukhipha i-grouting.
Gcoba amathayili usebenzisa i-grout material efanelekile, ugcwalise amalunga ngokuphelele futhi ululaze ubuso.
4.Ubuhle be-HPMC-Based Tile Adhesive:
Amandla Okubopha Okuthuthukisiwe: I-HPMC ithuthukisa ukunamathela kukho kokubili amathayela nama-substrates, inciphisa ubungozi bokuqoqwa kwamathayela.
Ukusebenza Okuthuthukisiwe: Ukuba khona kwe-HPMC kuthuthukisa ukusebenza kanye nesikhathi esivulekile sokunamathela, okuvumela ukusetshenziswa okulula nokulungiswa kwamathayili.
Ukugcinwa Amanzi: I-HPMC isiza ukugcina umswakama ngaphakathi kwe-adhesive, ikhuthaza ukugeleza okufanele kukasimende futhi ivimbele ukomiswa ngaphambi kwesikhathi.
Okunamathelayo okusekelwe kuthayela okusekelwe ku-HPMC kunikeza isixazululo esithembekile sezinhlelo zokusebenza ezihlukene zamathayili, ukuhlinzeka ngokunamathela okuqinile, ukusebenza okuthuthukisiwe, nokuqina okuthuthukisiwe.Ngokuqonda ukwakheka nezindlela zokusetshenziswa ezichazwe kulo mhlahlandlela, ochwepheshe bezokwakha bangasebenzisa ngempumelelo okunamathelayo kwe-HPMC ukuze kuzuzwe ukufakwa kwamathayela kwekhwalithi ephezulu.
