Ixesha elivulekileyo elongezelelweyo livumela ukuguquguquka okukhulu kunye nokulula ekulungiseni iileyili emva kokuba zibekwe, ziqinisekisa ukulungelelaniswa okuchanekileyo kunye nokubeka. Oku kunenzuzo ngakumbi kwiithayile zefomati enkulu kunye neepateni ezintsonkothileyo zeethayile ezifuna ukubekwa ngononophelo.
4. Ukumelana ne-Sag
I-HPMC iphucula ukuxhathisa kwe-sag yezinto zokuncamathelisa iithayile, okukukwazi ukuncamathelisa ukubamba iithayile endaweni ngaphandle kokutyibilika okanye ukuhexa, ngakumbi kumphezulu othe nkqo. Le propati ibaluleke kakhulu kufakelo lweethayile eludongeni, apho ubunzima bunokubangela ukuba iithayile zityibilike phambi kokuba i-adhesive iseti. Ngokuphucula ukuxhathisa kwe-sag, i-HPMC iqinisekisa ukuba iithayile zihlala zikhuselekile ngexesha nasemva kofakelo, okukhokelela ekugqityweni okuzinzileyo kunye nokuqina.
5. Ukuphuculwa kokuqina kokubambelela
Ubukho be-HPMC kwi-adhesives ye-tile kwandisa amandla okubambelela phakathi kweetayile kunye ne-substrate. I-HPMC isebenza njenge-binder, ikhuthaza intsebenziswano engcono kunye nokudibanisa kwi-interface. Oku kuphucuka kwamandla okubambelela kuqinisekisa ukuba iithayile zihlala zincanyathiselwe ngokukhuselekileyo ekuhambeni kwexesha, naphantsi kweemeko ezahlukeneyo zokusingqongileyo ezifana nokuguquguquka kobushushu kunye nokuvezwa komswakama.
6. Umkhenkce-Thaw uzinzo
I-HPMC inegalelo kwi-frize-nyibilika uzinzo lwezincamathelisi zethayile, oko kukuthi isakhono sokuncamathelisa ukumelana nemijikelo yokukhenkceza kunye nokunyibilika ngaphandle kokuthotywa. Le propati ibaluleke kakhulu kwimimandla enemozulu ebandayo apho i-adhesives inokuthi ixhomekeke kwiimeko ezinjalo. I-HPMC inceda ukugcina ingqibelelo kunye nokusebenza kwe-adhesive, ukuthintela imiba efana nokuqhekeka okanye ukulahleka kokubambelela.
7. Ukungqinelana kunye nokufanayo ekuxubeni
I-HPMC inceda ekufezekiseni umxube ohambelanayo kunye nofanayo xa ulungiselela izinto zokuncamathelisa iithayile. Ukunyibilika kwayo kunye nokukwazi ukusabalalisa ngokulinganayo emanzini kuqinisekisa ukuba amacandelo anamathele ahlanganiswe kakuhle, okubangela umxube we-homogenous. Oku kuhambelana kubalulekile ekusebenzeni kwe-adhesive, njengoko ukusasazwa kokungalingani kwamacandelo kunokukhokelela kwiindawo ezibuthathaka kunye nokunciphisa ukusebenza kakuhle.
8. Ukuphucula ukuguquguquka kunye ne-Crack Resistance
Ngokubandakanya i-HPMC, i-adhesives ye-tile ifumana ukuguquguquka okuphuculweyo kunye nokumelana nokuqhekeka.
