Izinamathiselo zamathayela zivame ukusetshenziswa embonini yokwakha ukuze kwakheke isibopho esiqinile nesihlala isikhathi eside phakathi kwamathayili nama-substrates. Kodwa-ke, ukuzuza isibopho esivikelekile nesihlala isikhathi eside phakathi kwamathayili nama-substrates kungaba inselele, ikakhulukazi uma indawo engaphansi ingalingani, ingcolile noma inezimbotshana.
Eminyakeni yamuva nje, ukusetshenziswa kwe-hydroxypropyl methylcellulose (HPMC) kuma-adhesives we-tile kuye kwanda kakhulu ngenxa yezakhiwo zayo zokunamathisela ezinhle kakhulu. I-HPMC iyi-polymer esebenzayo etholakala ku-cellulose evame ukusetshenziswa njenge-thickener, stabilizer kanye ne-ejenti emisayo embonini yemithi, yezimonyo neyokudla. I-HPMC iphinde isetshenziswe kabanzi embonini yezokwakha, ikakhulukazi kuma-adhesives amathayela, njengoba i-viscosity yayo ephezulu ithuthukisa izakhiwo zokubopha zama-tile.
Thuthukisa izakhiwo zokubopha amathayela e-ceramic usebenzisa i-HPMC ene-viscosity ephezulu
1. Yehlisa ukumuncwa kwamanzi
Enye yezinselelo ezibalulekile ekufinyeleleni isibopho esiqinile phakathi kwe-tile ne-substrate amanzi abamba i-substrate, okwenza okunamathelayo kudonse futhi kuhluleke. I-HPMC iyi-hydrophobic futhi isiza ukwehlisa ukumuncwa kwamanzi yi-substrate. Uma i-HPMC yengezwa kuma-adhesives we-tile, yenza ungqimba ku-substrate evimbela ukungena kwamanzi futhi inciphise ingozi yokuxhuma.
2. Thuthukisa ukusebenza
Ukwengeza i-high-viscosity HPMC ku-adhesive tile kungathuthukisa kakhulu ukusebenza kokwakhiwa kwe-adhesive. I-HPMC ene-viscosity ephezulu isebenza njenge-thiener, inikeze ingcina ukuthungwa okubushelelezi nokungaguquguquki. Lokhu kuvumelana okuthuthukisiwe kwenza kube lula ukusebenzisa okunamathelayo ku-substrate, kunciphisa ubungozi bokucwila noma ukuconsa nokudala isibopho esiqinile phakathi kwethayili ne-substrate.
3. Thuthukisa ukunamathela
I-viscosity ephezulu ye-HPMC ingaphinda ithuthukise ukubopha kwethayela ngokuthuthukisa izakhiwo zokubopha zokunamathisela. I-HPMC ene-viscosity ephezulu yenza amabhondi amakhemikhali aqinile ngokunamathela kuthayela kanye ne-substrate, yakhe ibhondi eqinile nethembekile. Ukwengeza, izakhiwo ezijiyayo ze-HPMC zinikeza ingcina amandla amakhulu okuthwala umthwalo, ngaleyo ndlela ithuthukise ukuqina kwebhondi.
4. Yehlisa ukushwabana
I-adhesive ye-tile enganele ingabangela ukuncipha, kushiye izikhala phakathi kwe-tile ne-substrate. Kodwa-ke, i-viscosity ephezulu ye-HPMC ingasiza ekunciphiseni ukushwabana kwe-adhesive yethayela ngokukhiqiza ukuvumelana okuzinzile nokungaguquguquki ngesikhathi sokufakwa. Ukuncipha kokuncipha kwandisa amandla ebhondi, okuqinisekisa ukuqina okunamathelayo okuhlala isikhathi eside.
5. Thuthukisa ukumelana nokuqhekeka
Amathayili e-Ceramic angaboshiwe kahle ku-substrate athambekele ekuqhekekeni nasekuphuleni. I-viscosity ephezulu ye-HPMC inezici ezinhle kakhulu zokulwa nokuqhekeka, okusiza ukuvimbela ukuqhekeka nokuqinisekisa ubude besikhathi sokunamathela kwethayela. I-HPMC isabalalisa ingcindezi ngokulinganayo, inikeza isibopho esiqinile, futhi imelana nokuqhekeka okuqondile nokuvundlile.
Ekuphetheni
I-viscosity ephezulu ye-HPMC idlala indima ebalulekile ekuthuthukiseni izakhiwo zokubopha amathayela, ikakhulukazi ezindaweni eziyinselele. Ukwengeza i-HPMC ku-adhesive tile kungathuthukisa ukusebenza, kunciphise ukumuncwa kwamanzi, kuthuthukise ukunamathela phakathi kwezinto eziyisisekelo nokunamathelisa amathayili, kunciphise ukushwabana, futhi kuthuthukise ukumelana nokuqhekeka kokunamathelayo.
Kuhle ukusho ukuthi i-HPMC ihambisana nemvelo futhi ayinabo ubuthi, okuyenza ibe inketho efanelekile yamaphrojekthi wethayela le-ceramic ezindaweni ezizwela imvelo. Ngakho-ke, ukusebenzisa i-high-viscosity HPMC kuma-adhesives we-tile akugcini nje ukuthuthukisa ikhwalithi ye-adhesive, kodwa futhi kukhuthaza ukusimama kwemvelo nokuphepha.
Imboni yezokwakha ingazuza kakhulu ekusetshenzisweni kwe-high-viscosity HPMC kuma-adhesive tile. Kungumkhiqizo ophephile, osebenzayo, osebenziseka kalula oqinisa isibopho phakathi kwamathayili ne-substrate, oqinisekisa ukuqina okuhlala isikhathi eside. Ngokusebenzisa le nto, abantu bangajabulela ukuqina okuthe xaxa, izindleko eziphansi zokunakekela, ukusebenziseka kalula, kanye nobungane bendawo yonke.
