Embonini yezokwakha, izinto zokunamathisela ezisekelwe kusimende zidlala indima ebalulekile ekuqinisekiseni ukuqina nokuhlala isikhathi eside kwezindawo zamathayili.Lezi zinamathiselo zibalulekile ekubopheni ngokuqinile amathayela kuma-substrates afana nokhonkolo, udaka, noma izindawo ezikhona zamathayela.Phakathi kwezingxenye ezihlukahlukene ze-adhesives tile-based adhesives, i-hydroxypropyl methylcellulose (HPMC) ivelele njengesithako esiyinhloko ngenxa yezakhiwo zayo eziningi kanye negalelo ekusebenzeni kwesistimu yokunamathela.
1. Qonda i-HPMC:
IHydroxypropylmethylcellulose (HPMC) i-nonionic cellulose ether etholakala kuma-polymers emvelo, ngokuyinhloko i-cellulose.Ivame ukusetshenziswa ezintweni zokwakha njenge-modifier ye-rheology, i-ejenti yokugcina amanzi kanye ne-adhesive.I-HPMC ihlanganiswa ngochungechunge lokuguqulwa kwamakhemikhali ku-cellulose, okuholela ekubeni i-polymer encibilika emanzini enezakhiwo eziyingqayizivele ezifanele ukusetshenziswa okuhlukahlukene embonini yokwakha, ekhemisi nokudla.
2.Iqhaza le-HPMC ekunamathiseleni kwethayela okusekelwe kusimende:
Ukugcinwa kwamanzi: I-HPMC inokugcinwa kwamanzi okuhle kakhulu, okuvumela okunamathelayo ukuthi kugcine ukuvumelana okufanele nokusebenza ngokuhamba kwesikhathi.Lesi sakhiwo sibalulekile ukuvimbela ukomiswa ngaphambi kwesikhathi kwe-adhesive, ukuqinisekisa ukugeleza okwanele kwezingxenye zikasimende, nokuthuthukisa amandla esibopho phakathi kwe-tile ne-substrate.
Ukuguqulwa Kwe-Rheology: I-HPMC isetshenziswa njengesilungisi se-rheology, esithinta ukuziphatha kokugeleza kanye ne-viscosity yezinto ezinamathelayo ezisekelwe kusimende.Ngokulawula i-viscosity, i-HPMC ingakwazi ukusebenzisa ingcina kalula, ithuthukise ukumbozwa futhi inciphise ubungozi bokushelela kwamathayili ngesikhathi sokufakwa.Ukwengeza, kusiza ukushelela okushelelayo futhi kuthuthukise ukusakazeka kwe-adhesive, ngaleyo ndlela kuthuthukise ukusebenza kahle futhi kunciphise amandla omsebenzi.
Ukunamathela Okuthuthukisiwe: I-HPMC isebenza njenge-adhesive, ikhuthaza ukunamathela phakathi kwe-adhesive ne-tile surface kanye ne-substrate.Isakhiwo sayo samangqamuzana sakha ifilimu enamathelayo lapho ifakwe amanzi, ihlanganisa ngempumelelo ingcina ezintweni ezihlukahlukene, okuhlanganisa i-ceramics, porcelain, itshe lemvelo kanye nama-substrates kakhonkolo.Lesi sakhiwo sibalulekile ekuzuzeni ukunamathela okuqinile, okuhlala isikhathi eside, ukuvimbela ukuhlukaniswa kwamathayili nokuqinisekisa ubuqotho besakhiwo sendawo yethayili.
I-Crack Resistance: I-HPMC inikeza ukuguquguquka kokunamathela kwethayela okusekelwe kusimende futhi ithuthukisa ukumelana nokuqhekeka.Ngenxa yokuthi amathayili angaphansi kwengcindezi yemishini kanye nokunyakaza kwesakhiwo, okunamathelayo kufanele kunwebeka ngokwanele ukuze kuhambisane nalokhu kunyakaza ngaphandle kokuqhekeka noma ukubola.I-HPMC ithuthukisa ukuguquguquka kwe-matrix enamathelayo, inciphisa amandla okuqhekeka futhi iqinisekise ukuqina kokufakwa kwamathayela, ikakhulukazi ezindaweni ezinethrafikhi ephezulu noma izindawo ezijwayele ukushintsha kwezinga lokushisa.
Ukuqina Nokumelana Nesimo Sezulu: Ukwengezwa kwe-HPMC kuthuthukisa ukuqina kanye nokumelana nesimo sezulu kwezinamatheliso zamathayela asekelwe kusimende.Inikeza ukumelana okukhulayo ekungeneni kwamanzi, imijikelezo yokuncibilika kweqhwa kanye nokuchayeka kwamakhemikhali, kuvimbele ukuwohloka nokugcina ubuqotho bendawo yamathayili ekusetshenzisweni kwangaphakathi nangaphandle.Ukwengeza, i-HPMC isiza ukunciphisa imiphumela yesimo sezulu, iqinisekisa ukuthi ukufakwa kwamathayela kuhlala kukuhle ngokuhamba kwesikhathi.
3. Ubuhle be-HPMC kumathayela asekelwe kusimende:
UKUSEBENZA OKUTHUTHUKISIWE: I-HPMC ithuthukisa ukusebenza kokufakwa kwamathayela asekelwe kusimende, ikwenze kube lula ukuxutshwa, ukukufaka nokushelela.Osonkontileka bangafinyelela imiphumela engaguquki ngomzamo omncane, ukonga isikhathi nemali phakathi nenqubo yokufaka.
Amandla Ebhondi Ethuthukisiwe: Ukuba khona kwe-HPMC kukhuthaza isibopho esiqinile phakathi kwethayela, okunamathelayo kanye ne-substrate, okuholela kumandla ebhondi aphakeme kanye nengozi encishisiwe yokuqoqwa kwamathayela noma ukwehluleka.Lokhu kuqinisekisa ukusebenza kwesikhathi eside nokuzinza kwendawo yethayela ezindaweni ezihlukahlukene.
Ukuhlukahluka: Okunamathelayo okusekelwe kuthayela okusekelwe ku-HPMC kuyahlukahluka futhi kufanelekile ukusetshenziswa ezinhlotsheni ezihlukahlukene zamathayela, osayizi nama-substrates.Ukuthi bafaka i-ceramic, porcelain, itshe lemvelo noma ithayela le-mosaic, osonkontileka bangathembela ezintweni ezinamathelayo ze-HPMC ukuze balethe imiphumela engaguquki kusukela kuphrojekthi kuye kwelinye.
Ukuhambisana: I-HPMC iyasebenzisana nezinye izithasiselo nezixube ezivame ukusetshenziswa kumathayela kasimende, njengezilungisi ze-latex, ama-polymers namakhemikhali athuthukisa ukusebenza.Lokhu kuhambisana kuvumela ukwakheka okwenziwe ngendlela oyifisayo ukuhlangabezana nezimfuneko ezithile zokusebenza nezidingo zephrojekthi.
Ukusimama: I-HPMC ithathwe emithonjeni ye-cellulose evuselelekayo, okuyenza ibe ukukhetha okuvumelana nemvelo ezintweni zokwakha.I-biodegradability yayo kanye nomthelela ophansi kwezemvelo kunomthelela ezenzweni zokwakha ezisimeme kanye nezinhlelo zokwakha eziluhlaza.
4. Ukusetshenziswa kwe-HPMC kokunamathela kuthayela okusekelwe kusimende:
I-HPMC isetshenziswa kabanzi ezinhlotsheni ezahlukene zokunamathelisa amathayela asuselwa kusimende okuhlanganisa:
I-Standard Thin Form Mortar: I-HPMC ivamise ukusetshenziswa odakeni olujwayelekile lwefomu elincanyana ukuze kuhlanganiswe izitsha zobumba kanye namathayili e-ceramic kuma-substrates afana nokhonkolo, ama-screeds namabhodi asekela usimende.Ukugcinwa kwayo kwamanzi kanye nezakhiwo zokunamathela ziqinisekisa ukusebenza okuthembekile kokufakwa kwamathayela angaphakathi nangaphandle.
I-Adhesive Yefomethi Enkulu Yamathayela: Ekufakweni okubandakanya amathayela efomethi enkulu noma amathayela amatshe emvelo asindayo, okunamathelayo okusekelwe ku-HPMC kunikeza amandla ebhondi athuthukisiwe kanye nokumelana nokuqhekeka, okujwayelana nesisindo nezici zobukhulu zethayela.
Izinamathiselo Zethayela Ezivumelanayo: Kuzinhlelo zokusebenza ezidinga ukuguquguquka nokukhubazeka, njengokufakwa kuma-substrates ajwayele ukunyakaza noma ukunwetshwa, i-HPMC ingakwazi ukwenza okunamathelayo okuguquguqukayo kwethayela okungamelana nokucindezeleka kwesakhiwo kanye nezimo zemvelo ngaphandle kokuthikameza ukunamathela.ukulingana noma ukuqina.
I-Hydroxypropyl methylcellulose (HPMC) idlala indima ebalulekile ekwakhiweni nasekusebenzeni kwezinamathelisi zamathayili asekelwe kusimende, ihlinzeka ngezici ezihlukahlukene nezinzuzo ezidingekayo ukuze kufakwe ithayela ngempumelelo.Kusukela ekuthuthukiseni ukunamathela namandla ebhondi kuya ekuthuthukiseni ukusebenza nokuhlala isikhathi eside, i-HPMC isiza ukuthuthukisa ikhwalithi, ukwethembeka nokuhlala isikhathi eside kwezindawo zamathayili e-ceramic kumaphrojekthi wokwakha ahlukahlukene.Njengoba imboni yezokwakha iqhubeka nokubeka eqhulwini ukusebenza kahle, ukusimama nokusebenza, ukubaluleka kwe-HPMC ezintweni ezinamathelayo ezisekelwe kusimende kusalokhu kuyingxenye, okuqhubekisela phambili ukusungulwa kanye nentuthuko kubuchwepheshe bokufaka amathayela.
