I-HPMC okanye i-hydroxypropyl methylcellulose yi-ether yeselulosi esetyenziswa kakhulu kushishino. I-polymer eyenziwe nge-cellulose, ephuma kwi-pulp yomthi, ikotoni okanye ezinye iifayili zendalo. Izityebi ze-HPMC zineepropathi ezigqwesileyo zokujiya, ukubopha kunye nokuxhoma kwaye zisetyenziswa kumashishini ahlukeneyo aquka ukwakhiwa, ukutya, amayeza, iimveliso zokhathalelo lomntu nokunye.
Esinye sezicelo eziphambili ze-HPMC zokujiya zifana ne-thickener kwi-interface agents. Ii-agent ze-Interfacial zixhobo ezisebenza njengesithintelo phakathi kweendawo ezimbini zokuthintela ukuba zingadibanisi ngokuthe ngqo. Zisetyenziselwa ukuphucula umgangatho wemveliso kunye nokunciphisa iindleko zokuvelisa ngokwenza i-adhesive layer phakathi kwe-substrates. I-HPMC ineempawu ezigqwesileyo zokujiya ezinceda ukwenza umaleko wokuncamathelisa phakathi kwe substrates.
Ukusetyenziswa kwe-HPMC thickener kwi-arhente yojongano kunceda ukuphucula ukusebenza kwemveliso. Kwishishini lokwakha, umzekelo, isetyenziswe njenge-thickener kwi-adhesives tile, i-plaster kunye nodaka. HPMC thickeners ukunceda ukwenza umaleko bond phakathi komphezulu kunye nokuncamathelisa, ngaloo ndlela ukwandisa isakhono yayo bonding. Kwakhona kwandisa ukuqina kwe-adhesive kunye nokukwazi ukugcina amanzi, okwenza kube lula ukusebenza kunye nokunciphisa umngcipheko weentanda okanye ezinye iziphene.
Elinye ishishini elinokuthi lixhamle kwi-HPMC lishishini lokutya. Isetyenziswa ekutyeni njenge-thickener, emulsifier kunye ne-stabilizer. Ngokuqhelekileyo kufumaneka ekutyeni okucutshungulwayo okufana neesosi, iisuphu, kunye neegravies. I-HPMC thickeners inceda ukudala ukuthungwa okugudileyo, okungaguquguqukiyo ekutyeni, ukuthintela ukwahlula okanye ukujiya. Kwakhona kwandisa ubomi beshelufu yemveliso, ukuyigcina intsha ixesha elide.
Kwiimveliso zokhathalelo lomntu ezifana neloshini, iishampu kunye nezithambiso, izityebi zeHPMC zisetyenziselwa ukuphucula ukuthungwa kunye nokungaguquguquki kweemveliso. Ikwanceda ukuzinzisa iimveliso kwaye ibathintele ukuba bahlukane ngokuhamba kwexesha. Izityebi ze-HPMC zikhuselekile kwaye zinokhetho olusebenzayo kwii-synthetic thickeners eziqhele ukusetyenziswa kwiimveliso zokhathalelo lomntu.
Ishishini loxubo-mayeza likwaxhamla kusetyenziso lwezitshizi ze-HPMC. Isetyenziswa njenge-binder, i-emulsifier kunye ne-arhente yokumisa kwiyeza. I-HPMC thickener inceda ukuzinzisa izithako ezisebenzayo kwichiza, iqinisekisa ukusebenza kwayo kunye nokhuseleko. Isenokuphucula incasa kunye nenkangeleko yamachiza, iwenze abe nencasa ngakumbi kwaye kube lula ukuwaphatha.
Ukuqukumbela, i-HPMC thickener yimathiriyeli eguquguqukayo nexabisekileyo esetyenziswa kumashishini ahlukeneyo ngokujiya, ukubopha kunye nokuxhoma iipropathi. Kuye kwangqinwa ukuba kusebenza ngokukodwa ekuphuculeni ukusebenza kwemveliso xa isetyenziswe njenge-thickener kwi-interface agents. Ikwayindlela ekhuselekileyo nengabizi kakhulu kwi-synthetic thickeners, iyenza ibe lukhetho oludumileyo kwizicelo ezininzi. Njengoko amashishini amaninzi efumanisa izibonelelo zee-HPMC thickeners, imfuno yayo kulindeleke ukuba ikhule ngakumbi kwixesha elizayo.
