I-HPMC (i-hydroxypropyl methylcellulose) yinto ebalulekileyo yokwakha, ngokukodwa isetyenziswe ngokubanzi kwiinkqubo zokwakha ezifana nokubeka i-tile. I-ether ye-cellulose engekho i-ionic efunyenwe ngokuguqulwa kweekhemikhali zemicu ye-cotton yendalo. I-HPMC idlala indima ephambili kwizinto zokuncamathelisa iithayile ngenxa yokusebenza kwayo okugqwesileyo.
1. Ukuqina kwesiphumo
I-HPMC ineempawu ezintle zokutyeba, ezinokunyusa i-viscosity ye-adhesives tile, okwenza kube lula ukusasazeka kwindawo yokwakha kunye nokugcina isicelo esifanayo. Ipropathi yokuqina ayiphuculi kuphela ukusebenza kolwakhiwo, kodwa inceda nokugcina ixesha elide elivulekileyo ngexesha lokwakha, oko kukuthi, iileyili zinokuhlengahlengiswa kwisithuba sexesha emva kwesicelo.
2. Ukugcinwa kwamanzi
Omnye umsebenzi obalulekileyo we-HPMC kukugcina amanzi. Ngethuba lokusetyenziswa kwe-adhesives ye-tile, umlinganiselo othile wamanzi ufunekayo ukuze kuqinisekiswe ukuba i-samente okanye ezinye izinto ze-cementous ziyakwazi ukudibanisa kunye nokuqina ngokuqhelekileyo. Ukuba amanzi alahlekile ngokukhawuleza, izinto ze-cementitious azikwazi ukusabela ngokupheleleyo, okubangela ukuhla kwamandla okudibanisa. I-HPMC inokuthintela ngokufanelekileyo ilahleko yamanzi, igcine amanzi kwi-adhesive, kwaye inike i-adhesive ixesha elaneleyo lokuqinisa kunye nokwenza umaleko oqinileyo wokubopha.
3. Ipropati ye-Anti-slip
Kwi-tile yokubeka, ipropati echasene ne-slip ibaluleke kakhulu kuba iileyile zilula ukutyibilika xa zifakwe kwiindonga okanye kwiindawo ezithe nkqo. I-HPMC ikwandisa i-thixotropy ye-adhesive, iqinisekisa ukuba iileyili zinokuqiniswa ngokuqinileyo kwiindawo ezithe nkqo ngaphandle kokutyibilika, ngaloo ndlela kuphuculwe ukuchaneka kolwakhiwo.
4. Ukwandisa ixesha elivulekileyo
Ngethuba lenkqubo yokwakha, ixesha elivulekileyo libhekisela kwifestile yexesha apho i-adhesive tile ihlala ibambelele ngokufanelekileyo emva kokusetyenziswa. I-HPMC inokwandisa ngokufanelekileyo ixesha elivulekileyo, ivumela abasebenzi ukuba bahlengahlengise kwaye babeke iithayile ixesha elide, ukuphucula ukuguquguquka kolwakhiwo, ngokukodwa ukulungelelaniswa kweemeko ezinkulu zokubeka okanye eziyinkimbinkimbi zokwakha.
5. Ukuphucula amandla okudibanisa
I-HPMC ingaphucula amandla okudityaniswa kwezinto zokuncamathelisa iithayile. Xa isetyenziswe ngokudibeneyo kunye nezixhobo ze-inorganic ezifana ne-samente, ubukho be-HPMC bunokuphucula ngokubonakalayo iimpawu zokubambisana kwe-adhesive, ukuqinisekisa ukuba iithayile ezibekwe ziqinile kwaye aziwi emva kokunyanga, kwaye zigcine uzinzo ixesha elide.
6. Ukuphucula ukusebenza kolwakhiwo
I-lubricity ye-HPMC yenza ukuba i-adhesive ibe lula ukuyisebenzisa, ngakumbi ngexesha lokubeka i-scale-scale, inokwenza isicelo sibe lula kwaye sinciphise ukunyanzeliswa komzimba kwabasebenzi bokwakha. Kwangaxeshanye, i-dispersibility ebalaseleyo ye-HPMC inokwenza amacandelo ahlukeneyo asasazwe ngokulinganayo ngexesha lokuvuselela, ngokuphucula ukufana komxube.
7. Ukuxhathisa imozulu kunye nokunganyangeki komkhenkce
Ngenxa yokuxhathisa imozulu elungileyo kunye nokumelana nomkhenkce, i-HPMC ingabonisa ukusebenza okuzinzileyo phantsi kweemeko zemozulu ezahlukeneyo. Ngokukodwa kwiindawo ezibandayo, i-adhesives ye-tile inokufumana imijikelezo ye-freeze-thaw ephindaphindiweyo, ebeka iimfuno eziphezulu kwiipropati zabo zokubambisana. I-HPMC inokunceda izinto ezincamathelayo zigcine amandla azo okubopha kunye nokuqina phantsi kwezi meko.
Indima ye-HPMC kwi-adhesives ye-tile i-multifaceted, kubandakanywa ukuqina, ukugcinwa kwamanzi, ukuphucula amandla okudibanisa, ukuchasana kunye nokwandisa ixesha elivulekileyo. Kungenxa kanye ngenxa yezi zakhiwo zibalaseleyo ukuba i-HPMC ibe sisongezo esiyimfuneko kwintsimi yolwakhiwo, ngakumbi ekubekweni kweethayile. Ukusetyenziswa kwayo akukwazi nje ukuphucula kakhulu ukusebenza kakuhle kolwakhiwo, kodwa kwakhona kuqinisekisa ukuzinza kwexesha elide emva kokubeka.
