Ukuphucula iipropati ze-ceramic yokudibanisa iithayile usebenzisa i-HPMC ephezulu ye-viscosity

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 iye yanda 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 kushishino lokwakha, ngakumbi kwi-adhesives ye-tile, njengoko i-viscosity yayo ephezulu iphucula iimpawu 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 kwi-adhesives ye-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 ye-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, ekulula 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.
