Adhesives tile ajwayele ukusetshenziswa embonini yezokwakha ukudala ubuhlobo obuqinile nobuhlala isikhathi eside phakathi kwamathayili nezindawo zokunyumba. Kodwa-ke, ukufeza isibopho esivikelekile nesihlala isikhathi eside phakathi kwamathayili nezindawo zokunyumba kungaba inselele, ikakhulukazi uma indawo engezansi engalingani, ingcolisiwe noma i-porous.
Eminyakeni yamuva nje, ukusetshenziswa kwe-Hydroxypropyll methylcellulose (HPMC) kuma-tile adhesives sekuye kwathandwa kakhulu ngenxa yezakhiwo zayo ezinhle kakhulu ezinamathela. I-HPMC iyi-polymer esebenzayo ethathwe ku-cellulose esetshenziswa kakhulu njenge-swerener, i-stabilizer kanye ne-ejenti yokumisa izimboni ezenzakalisayo, izimonyo kanye nokudla. I-HPMC nayo isetshenziswa kabanzi embonini yezokwakha, ikakhulukazi emathangeni amathayili, njengoba i-viscosity yayo ephezulu ithuthukisa izibopho zokubopha amathayili.
Thuthukisa izakhiwo ze-Ceramic Tile Bondings usebenzisa i-HPMC ephezulu
1. Yehlisa ukumuncwa kwamanzi
Enye yezinselelo ezibalulekile ekuzuzeni isibopho esiqinile phakathi kwethayela ne-substrate yindawo yokuthola amanzi engaphansi, okwenza ukuba nokunamathela ku-demond nokwehluleka. I-HPMC i-hydrophobic futhi isiza ukunciphisa ukumuncwa kwamanzi nge-substrate. Lapho i-HPMC yengezwa kuma-tile anamathela, yakha ungqimba engxenyeni engezansi evimba ukungena kwamanzi futhi inciphise ingozi yokudonswa kwemali.
2. Thuthukisa ukusebenza
Ukungeza i-HPMC evuselelayo ye-HPMC kuya ku-Tile Adhesive kungathuthukisa kakhulu ukusebenza kokwakha kokunamathela. I-viscosite ephezulu i-HPMC isebenza njengomkhulu, inikeze ukunamathela kokuthungwa okubushelelezi nokungaguquki. Lokhu kuguquguquka okuthuthukile kwenza kube lula ukusebenzisa ukunamathela ku-substrate, kunciphisa ubungozi bokudambisa noma ukudonsa kanye nokwakha isibopho esiqinile phakathi kwethayela ne-substrate.
3. Thuthukisa ukunqwabelana
I-Vissevotity ephezulu ye-HPMC ingaphinde ibe ngcono ukubopha ama-tile ngokwenza ngcono izakhiwo ezibophayo zokunamathela. I-Vispositity HPMC ephezulu yakha ama-bond amakhemikhali aqinile nge-tile adhesive kanye ne-substrate, ukudala isibopho esinamandla nesinokwethenjelwa. Ngokwengeziwe, izakhiwo ezikhuthele ze-HPMC zinikeza ukunamathela ngamandla amakhulu omthwalo, ngaleyo ndlela kuthuthukise ukuqina kwesibopho.
4. Yehlisa i-shrinkage
Ukunamathela kwe-tile enganele kungadala ukushwabana, kushiye izikhala phakathi kwethayela kanye ne-substrate. Kodwa-ke, i-viscosity ephezulu i-HPMC ingasiza ekunciphiseni i-shrinkage ye-tile anamathelayo ngokukhiqiza ukuvumelana okuzinzile futhi okungaguquki ngesikhathi. Ukuncipha kwe-shrinkage kwandisa amandla e-bond, kuqinisekisa ukuqina okunamatheyisi okuhlala isikhathi eside.
5. Thuthukisa ukumelana nokuqhekeka
Amathayili we-Ceramic ahlanganiswe kabi engxenyeni engezansi ethambekele ekuqhekekeni nasekuqhekekeni. I-viscosity ephezulu i-HPMC inezakhiwo ezinhle kakhulu zokulwa nokuqhekeka, isiza ukuvikela ukuqhekeka futhi iqinisekise isikhathi eside se-tile anamathelayo. I-HPMC ikwazisa ngokulinganayo ukucindezelwa, ihlinzeka ngesibopho esiqinile, futhi imelana nokuqhekeka okuqondile nokuvundlile.
Ekuphetheni
I-viscosity ephezulu i-HPMC idlala indima ebalulekile ekuthuthukiseni izakhiwo ezibophayo, ikakhulukazi ezindaweni eziyinselele. Ukungezwa i-HPMC kuya ku-tile adhesive kungathuthukisa ukusebenza, ukunciphisa ukumuncwa kwamanzi, ukuthuthukisa ukunamathela phakathi kwezimpahla eziyisisekelo nokunamathela okunamathela, futhi kuthuthukise ukumelana nokuqhekeka kokunamathela.
Kuyafaneleka ukusho ukuthi i-HPMC inobungani bemvelo futhi ingekho ubuthi, okwenza kube yisinqumo esihle samaphrojekthi we-ceramic tile ezindaweni ezibucayi emvelweni. Ngakho-ke, ukusebenzisa i-HPMC ephezulu ye-HPMC kuma-tile anama-adhesives awagcini nje ngokuthuthukisa ikhwalithi yokunamathela, kepha futhi athuthukisa ukuqina kwemvelo nokuphepha.
Imboni yezokwakha ingazuza kakhulu ekusetshenzisweni kwe-HPMC evuselelayo ye-HPMC ephakeme ngamathayithi anamathela. Kungumkhiqizo ophephile, osebenzayo, okusebenziseka kalula oqinisa ubuhlobo phakathi kwamathayili kanye ne-substrate, uqinisekise ukuqina okuhlala isikhathi eside. Ngokusebenzisa lokhu okuqukethwe, abantu abangakujabulela ukuqina okukhulayo, izindleko zokulungiswa okuphansi, ukusetshenziswa kalula, kanye nobungane bezemvelo bonke.
