I-adhesives ye-tile isetyenziswa ngokuqhelekileyo kwishishini lokwakha ukudala ibhondi eqinile kunye nexesha elide phakathi kweetayile kunye ne-substrates. Nangona kunjalo, ukufezekisa ibhondi ekhuselekileyo kunye nexesha elide phakathi kweetayile kunye ne-substrates kunokuba ngumngeni, ngakumbi ukuba i-substrate surface ayilingani, ingcolisekile okanye i-porous.
Kwiminyaka yakutshanje, ukusetyenziswa kwe-hydroxypropyl methylcellulose (HPMC) kwi-adhesives ye-tile kuye kwanda kakhulu ngenxa yeempawu zayo zokubambelela. I-HPMC yi-polymer esebenzayo ephuma kwi-cellulose edla ngokusetyenziswa njenge-thickener, i-stabilizer kunye ne-arhente yokumisa kwi-pharmaceutical, i-cosmetic kunye nemizi-mveliso yokutya. I-HPMC isetyenziswa ngokubanzi kwishishini lokwakha, ngakumbi kwi-adhesives yethayile, njengoko i-viscosity yayo ephezulu iphucula iipropathi zokubopha iithayile.
Ukuphucula iipropati ze-ceramic yokudibanisa iithayile usebenzisa i-HPMC ephezulu ye-viscosity
1. Nciphisa ukufunxwa kwamanzi
Enye yeengxaki ezibalulekileyo ekufezekiseni ibhondi eqinile phakathi kwe-tile kunye ne-substrate yi-substrate ethatha amanzi, ebangela ukuba i-adhesive idibanise kwaye ingaphumeleli. I-HPMC i-hydrophobic kwaye inceda ukunciphisa ukufunxwa kwamanzi yi-substrate. Xa i-HPMC yongezwa kwii-adhesives ze-tile, yenza umaleko kwi-substrate ekhusela ukungena kwamanzi kunye nokunciphisa umngcipheko wokudibanisa.
2. Ukuphucula ukusebenza
Ukongeza i-high-viscosity HPMC kwi-adhesive tile inokuphucula kakhulu ukusebenza kokwakhiwa kwe-adhesive. I-viscosity ephezulu ye-HPMC isebenza njenge-thickener, inika i-adhesive ukuthungwa okugudileyo kunye nokuhambelana. Oku kuhambelana okuphuculweyo kwenza kube lula ukusebenzisa i-adhesive kwi-substrate, ukunciphisa umngcipheko wokugubha okanye ukuxubha kunye nokudala ibhondi eqinile phakathi kwe-tile kunye ne-substrate.
3. Ukuphucula ukubambelela
I-viscosity ephezulu ye-HPMC inokwandisa ukudibanisa i-tile ngokuphucula iimpawu ze-adhesive. I-High-viscosity HPMC yenza iibhondi zeekhemikhali ezinamandla kunye ne-adhesive tile kunye ne-substrate, ukudala ibhondi eyomeleleyo kwaye ethembekileyo. Ukongeza, iipropathi ezityebileyo ze-HPMC zibonelela ngokuncamathelayo ngomthamo omkhulu wokuthwala umthwalo, ngaloo ndlela uphucula ukuqina kwebhondi.
4. Nciphisa ukushwabana
I-adhesive ye-tile enganeleyo ingabangela ukuhla, ukushiya izithuba phakathi kwe-tile kunye ne-substrate. Nangona kunjalo, i-viscosity ephezulu ye-HPMC inokunceda ukunciphisa i-shrinkage ye-adhesive tile ngokuvelisa ukuhambelana okuzinzile kunye nokuhambelana ngexesha lokusetyenziswa. Ukucutheka okucuthekileyo kwandisa amandla ebhondi, iqinisekisa ukuqina okuncamathelayo okuhlala ixesha elide.
5. Ukuphucula ukuxhathisa kokuqhekeka
Iithayile zeCeramic ezingabotshwanga kakuhle kwi-substrate zilungele ukuqhekeka kunye nokuqhekeka. I-viscosity ephezulu ye-HPMC ineempawu ezibalaseleyo zokuchasana nokuqhekeka, inceda ukuthintela ukuqhekeka kunye nokuqinisekisa ixesha elide lokuncamathelisa ithayile. I-HPMC isasaza ngokulinganayo uxinzelelo, inika ibhondi eyomeleleyo, kwaye iyaxhathisa ukuqhekeka okuthe nkqo nokuthe tye.
ukuququmbela
I-viscosity ephezulu ye-HPMC idlala indima ebalulekileyo ekuphuculeni iipropati ze-tile bonding, ngakumbi kwiindawo ezinomngeni. Ukongeza i-HPMC kwi-adhesive tile inokuphucula ukusebenza, ukunciphisa ukufunxa kwamanzi, ukuphucula ukunamathela phakathi kwezinto ezisisiseko kunye ne-adhesive tile, ukunciphisa i-shrinkage, kunye nokuphucula ukuxhathisa kokuqhekeka kwe-adhesive.
Kufanelekile ukukhankanya ukuba i-HPMC ihambelana nokusingqongileyo kwaye ayinayo ityhefu, iyenza ibe lolona khetho lufanelekileyo kwiiprojekthi zeethayile ze-ceramic kwiindawo ezinobuthathaka kokusingqongileyo. Ngoko ke, ukusebenzisa i-high-viscosity HPMC kwi-adhesives ye-tile ayiphuculi kuphela umgangatho we-adhesive, kodwa ikhuthaza ukuzinza kokusingqongileyo kunye nokhuseleko.
Ishishini lokwakha linokuzuza kakhulu ekusebenziseni i-HPMC ephezulu ye-viscosity kwi-adhesives tile. Yimveliso ekhuselekileyo, esebenzayo, elula ukuyisebenzisa eyomeleza ibhondi phakathi kweetayile kunye ne-substrate, iqinisekisa ukuhlala ixesha elide. Ngokusebenzisa le mathiriyeli, abantu banokukonwabela ukomelela okongeziweyo, iindleko ezisezantsi zolondolozo, ukusebenziseka ngokulula, kunye nobuhlobo bendalo ngokubanzi.
