I-HPMC, egama layo elipheleleyo yi-Hydroxypropyl Methylcellulose, sisongezo sekhemikhali esisebenzayo esisetyenziswa ngokuqhelekileyo kwizinto zokwakha. Ekubekeni iithayile ze-ceramic, i-HPMC idlala indima ebalulekileyo kwaye isetyenziswa kakhulu kwi-adhesives ye-tile, i-putty powders, kunye nezinye i-mortars zokwakha ukuphucula ukusebenza kwezinto kunye nokulula ukwakhiwa.
1.Iipropati ezisisiseko ze-HPMC
I-HPMC yi-ether yeselulosi eyenziwe kwiselulosi yendalo eguqulwe ngokwekhemikhali. Ineempawu eziphambili zilandelayo:
Ukutyeba: I-HPMC inamandla okwandisa kakhulu i-viscosity yezinto ezingamanzi okanye ze-pasty, ebaluleke kakhulu kwi-adhesives ye-tile kunye ne-mortars. Izinto ezixubileyo zinokubambelela okungcono kwaye zinokuthintela ngokufanelekileyo iileyile ukuba zingatyibiliki ngexesha lokubeka.
Ukugcinwa kwamanzi: I-HPMC igcina ngokufanelekileyo amanzi kwizinto ezisekwe kwisamente, ukwandisa ixesha elivulekileyo lodaka lwakho okanye i-adhesive tile. Oku kuthetha ukuba abasebenzi banexesha elingakumbi lokulungelelanisa xa bebeka iithayile, kwaye kukwanceda isamente ukuba imanzise ngokupheleleyo, iphucule amandla okugqibela ebhondi.
Ukuthambisa: I-HPMC yenza udaka lubemanzi ngakumbi kwaye lusebenze, inciphisa ukungqubana ngexesha lokwakha kwaye ivumela abasebenzi ukuba babeke iithayile ngokulula ngakumbi.
Ukuncamathela: I-HPMC ibonelela ngeempawu zokuncamathelisa ezilungileyo, yenza ikhonkco phakathi kweethayile kunye ne-substrate yomelele kwaye inciphise umngcipheko wokuwa kweethayile.
2.Isicelo kwi-ceramic tile ebeka
Ekubekweni kweethayile ze-ceramic, i-HPMC isetyenziswa ikakhulu njengesilungisi sokuncamathelisa iithayile kunye nodaka. Ngokukodwa, i-HPMC idlale indima entle ekubekweni kwethayile yeceramic kule miba ilandelayo:
Ukuphucula ukusebenza kakuhle kolwakhiwo: I-HPMC ikwandisa ukugcinwa kwamanzi kunye nokusebenza kweglue yetayile, evumela abasebenzi ukuba babe nexesha elide lohlengahlengiso xa bebeka iithayile ngaphandle kokukhathazeka malunga nokumisa kweglu ngokukhawuleza. Oku kunciphisa amathuba okuphinda kusetyenzwe kwaye kuphuculwe ukusebenza kakuhle kolwakhiwo.
Ukuphuculwa komgangatho wokubeka: Ngokuphucula amandla okubopha i-tile yokunamathela, i-HPMC inceda ukukhusela iingxaki ezisemgangathweni ezifana nokugoba kunye nokuwa kweethayile ngexesha lokumisa. Ipropathi yayo yokuqina yenza ukuba i-adhesive ye-tile ingakwazi ukuhamba ngokukhawuleza xa ibeka kwiifacade okanye iisilingi, iqinisekisa ukucoceka kunye nokusebenza kakuhle kolwakhiwo.
Ukulungelelaniswa kwiindawo ezahlukeneyo zokwakha: Ukugcinwa kwamanzi okulungileyo okubonelelwa yi-HPMC kuvumela ukuba i-adhesive tile igcine ukusebenza okuzinzileyo kolwakhiwo kumaqondo okushisa aphezulu okanye kwiindawo ezomileyo, kwaye akuyi kubangela ukubambelela okunganeleyo ngenxa yokunyuka kwamanzi ngokukhawuleza.
3. Izilumkiso ngexesha lokwakha
Xa usebenzisa i-adhesive tile okanye udaka oluqukethe i-HPMC, abasebenzi kufuneka banikele ingqalelo kula manqaku alandelayo:
Umlinganiselo kufuneka uchaneke: inani le-HPMC lichaphazela ngokuthe ngqo ukusebenza kwe-adhesive tile. Kakhulu okanye kancinci kakhulu kuya kukhokelela kwiziphumo ezibi kakhulu zokwakha. Ngoko ke, ukulinganisa kufuneka kube ngokungqongqo ngokwemiyalelo yemveliso.
Hlanganisa kakuhle: Xa uqulunqa i-adhesive tile okanye i-mortar, i-HPMC kufuneka ixutywe ngokucokisekileyo kunye nezinye izinto ukuqinisekisa ukuba iimpawu zayo zingasetyenziswa ngokulinganayo. Ukuxuba okungafanelekanga kunokubangela ukunamathiswa kweendawo okungonelanga okanye ukomisa okungalinganiyo.
Gcina ucocekile: Ngexesha lenkqubo yokubeka iileyile ze-ceramic, izixhobo zokwakha kunye nokusingqongileyo kufuneka zigcinwe zicocekile ukuphepha ukungcola okuxutywayo kunye nokuchaphazela umphumo wokudibanisa.
Njengesongezo esakhiweyo esisebenzayo, i-HPMC idlala indima engenakuphinda ithathelwe indawo ekubekweni kweethayile zeceramic. Ayiphuculi nje kuphela ukusebenza kwee-adhesives tile kunye nodaka, kodwa iphucula ukusebenza kakuhle kolwakhiwo kunye nomgangatho wokugqibela. Ke ngoko, i-HPMC yinto ebaluleke kakhulu kwaye isetyenziswa ngokubanzi kulwakhiwo lwezakhiwo zanamhlanje.
