I-HPMC, ekwabizwa ngokuba yi-hydroxypropyl methylcellulose, yinxalenye yosapho lwee-ethers ze-cellulose.Ithathwe kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zesityalo.I-HPMC isetyenziswa ngokubanzi kushishino lokwakha ngenxa yeepropati zayo ezininzi.
I-HPMC iqhele ukusetyenziswa njenge-thickener, i-binder, ifilimu yangaphambili kunye ne-arhente yokugcina amanzi kwizinto zokwakha ezifana neemveliso ezisekwe kwisamente, izinto zokuncamathelisa iithayile, iiplates, iiplaster kunye neegrouts.Ubume bayo beekhemikhali buvumela ukuba bufunxe amanzi kwaye benze into efana ne-gel ephucula ukusebenza, ukunamathela kunye nokuxhatshazwa kwe-sag yezinto zokwakha.
Nazi ezinye iipropati eziphambili kunye nokusetyenziswa kwe-HPMC kushishino lokwakha:
Ukugcinwa kwamanzi: I-HPMC ifunxa kwaye igcine amanzi, ikhusela izinto ezisekwe kwisamente ukuba zome ngokukhawuleza.Oku kunceda ukunciphisa ukuqhekeka, kuphucula i-hydration kunye nokwandisa amandla onke kunye nokuqina kweemveliso zokwakha.
Ukuphuculwa kokuqhubela phambili: I-HPMC isebenza njenge-rheology modifier, ibonelela ngenkqubo engcono kunye nokusetyenziswa lula kwezinto zokwakha.Ukwandisa ukusasazeka kunye nokumelana nokudilika kodaka kunye ne-plasters, okwenza kube lula ukuphatha nokusebenzisa.
Ukubambelela kunye nokudibanisa: I-HPMC iphucula ukubambelela phakathi kwezinto zokwakha ezahlukeneyo.Yandisa amandla ebhondi yokuncamathelisa iithayile, iiplaster kunye ne-plasters, ukuqinisekisa ukunamathela okungcono kwii-substrates ezifana nekhonkrithi, iinkuni kunye neetayile.
I-Sag Resistance: I-HPMC inciphisa i-sag okanye ukuwa kwezinto eziphathekayo ezifana ne-adhesive tile okanye i-primer ngexesha lokufaka isicelo.Oku kunceda ukugcina ubukhulu obufunwayo kwaye kuthintele ukulwa okanye ukuvuza.
Ukwenziwa kwefilimu: Xa i-HPMC yomile, yenza ifilim ebhityileyo, ebhetyebhetye, ecacileyo.Le filimu inokubonelela ngokuchasana kwamanzi okungcono, ukuchasana kwemozulu kunye nokukhuselwa kwendawo yezinto zokwakha ezisetyenzisiweyo.
