Thuthukisa izakhiwo zokubopha amathayela e-ceramic usebenzisa i-HPMC ene-viscosity ephezulu

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, ingcolisiwe 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 kukhulisa 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.
