I-HPMC (i-hydroxypropyl methylcellulose) yi-cellulose-based nonionic polymer esetyenziswa ngokubanzi kumashishini okwakha, ukutya kunye namayeza. Kwintsimi yokwakha, i-HPMC isetyenziswa kakhulu njenge-thickener, i-arhente yokugcina amanzi, i-adhesive kunye ne-rheology modifier kwi-ceramic tile adhesive formulations. I-HPMC idlala indima ebalulekileyo ekuphuculeni ukuxhathisa ukutyibilika kunye nexesha elivulekileyo lokuqulunqa i-tile adhesive formulations.
Ukumelana ne-Slip kubhekiselele kwisakhono sokuncamathelisa itayile ukugcina amandla afunekayo okucheba ukuxhathisa ukufuduswa phantsi komthwalo othile. Ngamanye amazwi, ukuchasana kwe-slip kukubambelela kwi-tile kwi-substrate. I-adhesive ye-tile kufuneka ibe nokuchasana kakuhle kwe-slip ukuqinisekisa ukuba iithayile zihlala zikhuselekile kwindawo ngexesha nasemva kofakelo. Isizathu esona sizathu sokungonelanga ukuchasana kwe-slip kukungabikho kokubambelela phakathi kwe-adhesive kunye ne-substrate. Kulapho i-HPMC idlala indima ephambili ekuqulunqweni kwe-adhesive tile.
I-HPMC isebenza njenge-ejenti yokutyebisa kunye ne-agent yokugcina amanzi kwiifom ze-tile zokunamathela. Ithintela ukuhamba kwamanzi ngaphakathi kwe-adhesive, ngaloo ndlela ikhulisa i-viscosity yayo kwaye ngoko ke i-slip resistance. I-HPMC inika kwakhona ifilimu encinci, iyunifomu, eqhubekayo phakathi kwe-tile kunye ne-substrate. Ifilimu yenza ibhuloho phakathi kweendawo ezimbini, ukudala unxibelelwano olusondeleyo kunye nokuphucula i-adhesive grip kwi-tile.
I-HPMC ikwaphucula amandla okuqina kunye neepropathi zokwandiswa kwezinto zokuncamathelisa iithayile. Oku kuthetha ukuba xa umthwalo usetyenziswa kwiithayile, izinto zokuncamathelisa ezine-HPMC zithande ukukhubaza ngakumbi ngaphambi kokuqhekeka, ngaloo ndlela kwandisa amandla okuncamathela ukuxhathisa ukufuduswa.
Ixesha elivulekileyo libhekisela kwixesha apho i-adhesive tile ihlala isebenza emva kokusetyenziswa. Olu luphawu olubalulekileyo kwiifomula zokubambelela kwi-tile kuba ivumela i-installer ixesha elaneleyo lokulungelelanisa i-tile ngaphambi kokuba i-adhesive yome. I-HPMC yandisa ixesha elivulekileyo lokunamathelisa iithayile ngokusebenza njenge-rheology modifier.
I-Rheology sisifundo sendlela imathiriyeli ehamba ngayo kunye nokonakala. Ukwakhiwa kwe-adhesive ye-tile kufuneka ibe ne-rheology ethile yokugcina ukusebenza kunye nokubambelela. I-HPMC iguqula i-rheology ye-tile adhesive formulations ngokuchaphazela i-viscosity yabo, i-thixotropy, kunye neplastiki. HPMC kwandisa viscosity yokuncamathelisa ithayile, iyenza ibe nzima kwaye iyenze ulwelo ngaphantsi. Ukuhamba okucothayo kwenza ukuba i-adhesive ibe lula ukuyiqhuba kunye nefom, enceda ukwandisa ixesha elivulekileyo. I-HPMC inokuphucula i-thixotropy ye-adhesives tile. Thixotropy kukukwazi ukuncamathela ukubuyela kwi-viscosity yayo yasekuqaleni emva kokuphazamiseka. Oku kuthetha ukuba izinto ezincamathelayo ezine-HPMC azinakwenzeka ukuba zahlukane okanye zijike emva koguquko kwaye zinokubuyiselwa ekusebenzeni ixesha elide.
HPMC iphucula iplastiki yokuncamathelisa ithayile ceramic. I-Plastiki ibhekiselele kwisakhono sokuncamathelisa ukuhlala sisebenza phantsi kweemeko ezahlukeneyo zobushushu kunye nokufuma. Izinto zokuncamathelisa eziqulathe i-HPMC azichatshazelwa kukuguquguquka kobushushu kunye nokufuma kwaye zigcine ukusebenza kwazo kunye neempawu zokuncamathela. Le plasticity iqinisekisa ukuba i-adhesive tile ihlala isetyenziselwa ubomi bayo bonke benkonzo kwaye ayiyi kuqhekeka okanye ihlukane ne-substrate.
Indima ye-HPMC kwimixube yokuncamathelisa iithayile ukomeleza ukuxhathisa ukutyibilika kunye nexesha elivulekileyo libalulekile. Isebenza njenge-thickener, i-agent egcina amanzi, i-adhesive, i-rheology modifier, kwaye iphucula amandla okuqina, ukunyusa kunye neplastiki ye-adhesives ye-tile. Izinto zokuncamathelisa eziqulathe i-HPMC kulula ukuzisebenzisa, ziyaqhubekeka, kwaye zigcine ukuncamathela kubo bonke ubomi babo benkonzo. Ukusetyenziswa kwayo ngokubanzi kwiintlobo ngeentlobo zezicelo zokwakha kubonisa ukuba ikhuselekile, iyaguquguquka kwaye ineendleko ezifanelekileyo.
I-HPMC sisithako esiphambili kwiindlela zokuncamathelisa iithayile ukomeleza ukuxhathisa ukutyibilika kunye nexesha elivulekileyo. Iimpawu zayo zenza kube yinto efanelekileyo kubakhiqizi be-adhesive tile kunye neekontraki ezifuna ukuqulunqwa kwe-adhesive kunye nokusebenza, ukudibanisa kunye neepropati eziqinileyo zokubambisana. I-HPMC ke ngoko yenza igalelo elincomekayo kuyilo lwangoku kwaye ibonelela ngeenzuzo ezininzi ngaphandle kweempembelelo ezingalunganga kokusingqongileyo okanye kwimpilo yabantu.
