IHydroxypropyl methylcellulose (HPMC) iyinhlanganisela esetshenziswa kakhulu embonini yezokwakha, ikakhulukazi ekwakhiweni kokunamathela kwamathayela.Le polymer encibilika emanzini eguquguqukayo inezinhlobonhlobo zezakhiwo, okuyenza ibe isithako esidumile ekunamathiseleni, okokunamathela namanye amakhemikhali okwakha.
Isingeniso se-Hydroxypropyl Methylcellulose (HPMC)
IHydroxypropyl methylcellulose (HPMC) iyi-polymer engenabuthi, ephilayo, encibilika emanzini esetshenziswa kabanzi embonini yezokwakha.Iphuma ku-cellulose, i-polymer yemvelo etholakala okhunini nakwezinye izinto zezitshalo.I-HPMC ishintshwa amakhemikhali ngokwengeza i-hydroxypropyl kanye namaqembu e-methyl kumgogodla we-cellulose, ngaleyo ndlela ithuthukise ukugcinwa kwayo kwamanzi, ukujiya kanye nezakhiwo zokunamathela.
I-HPMC iyi-polymer eguquguqukayo engenziwa ngezifiso izidingo ezithile zomkhiqizo.Itholakala emabangeni ahlukene, kusukela kokuphansi kuya kokubonakala okuphezulu, futhi ingenziwa ngendlela oyifisayo ngamazinga ahlukene e-hydroxypropyl kanye ne-methyl substitution.Lokhu kuvumela abakhiqizi ukuthi balungise kahle izici zokusebenza zemikhiqizo yabo, bayenze isebenze kakhudlwana, ibe lula ukuyisebenzisa futhi ishibhile ukuyikhiqiza.
Izinzuzo ze-HPMC ku-adhesive tile
I-HPMC isetshenziswa kakhulu ekwenziweni kokunamathela kwethayela ngenxa yezinzuzo zayo eziningi.Nazi ezinye izizathu zokuthi kungani i-HPMC iyi-polymer ekhethwayo yokunamathela kuthayela:
1. Ukugcinwa kwamanzi
I-HPMC ingakwazi ukumunca futhi igcine amanzi amaningi, iyenze ibe i-ejenti enhle kakhulu yokugcina amanzi kuma-adhesive anamathelayo.Lokhu kubalulekile ngoba amanzi asiza ukwenza i-adhesive isebenze futhi ayibophe ku-substrate.Nge-HPMC, okunamathelayo kwethayela kuhlala kusebenza isikhathi eside, okunikeza isifaki isikhathi esengeziwe sokusebenzisa okunamathelayo nokulungisa ithayela ngaphambi kokuthi limiswe.
2. Ukuqina
I-HPMC iwugqinsi esenza okunamathelayo kuthayela kubonakale kakhudlwana, okusiza ukuthuthukisa amandla abo okubopha.I-HPMC ishubisa ingcina ngokubamba ama-molecule amanzi, ashubisa ingcina futhi yakhe ukunamathisela okungaguquki.Lokhu kwenza kube lula ukusebenzisa ingcina ngokulinganayo futhi kunciphisa ingozi yokuqhekeka kwezindebe (okungukuthi ukungalingani phakathi kwama-tile).
3. Thuthukisa ukunamathela
I-HPMC ithuthukisa ukunamathela kwezinamathelisi zamathayili ngenxa yezakhiwo zayo zokunamathisela.Uma yengezwa kokunamathelayo, i-HPMC yenza ifilimu elincanyana ebusweni be-substrate esiza ukuhlanganisa okunamathelayo kuthayela.Ifilimu iphinde ivimbele okunamathelayo ekumisweni ngokushesha, okubangela ukuthi ilahlekelwe amandla okubopha.
4. Ukuvumelana nezimo
I-HPMC ingenza izinamathiselo zamathayela zivumelane nezimo, okubalulekile ezindaweni ezihamba njalo, njengasezindaweni ezihlala noma ezizwa ukuzamazama komhlaba noma ukundindizela.I-HPMC isiza ukwenza ingcina inwebeka kakhulu, iyivumele ukuthi inyakaze futhi inyakaze nesakhiwo, inciphisa ubungozi bokuqhekeka kwama-tile noma ukuwa.
5. Impahla ye-anti-sag
I-HPMC isiza ukwehlisa ubungozi bokugoqa kwe-adhesive tile.Ngenxa yokujiya kwayo, i-HPMC isiza ukuvimbela ingcina ekusheleleni noma ehlehle odongeni ngaphambi kokuthi icutheke.Lokhu kungasiza abafaki ukufeza ukufakwa kwethayela okungaguquki futhi kunciphise isidingo sokusebenza kabusha.
Ekuphetheni
I-HPMC iyi-polymer eguquguqukayo enikeza izinzuzo eziningi embonini yezokwakha, ikakhulukazi ekwakhiweni kokunamathela kwamathayela.Ukugcina amanzi, ukujiya, ukubophezela, ukuguquguquka kanye nezindawo zokulwa nokuntenga ziyenza ibe isithako esikhethwayo phakathi kochwepheshe bezokwakha emhlabeni wonke.Ngokusebenzisa i-HPMC ukulungisa kahle izici zokusebenza kwezinamathelisi zamathayili, abakhiqizi bangakha izinto ezinamathelayo okulula ukuzisebenzisa, zibe namabhondi aqinile, ezikwazi ukumelana kangcono nokufuduka kanye nokumelana namanzi, futhi mancane amathuba okuthi zingaphumeleli.Akumangazi-ke ukuthi i-HPMC iyingxenye ebalulekile yemboni yezokwakha yanamuhla.
