IHydroxypropylmethylcellulose (HPMC) sisithako esisebenza ngeendlela ezininzi esisetyenziswa kakhulu kushishino lokwakha.Yipolymer ephilayo ephuma kwi-cellulose kwaye isetyenziswa njenge-thickener enyibilikayo emanzini, i-binder kunye nefilimu yangaphambili.I-HPMC idlala indima ebalulekileyo ekuqulunqweni kwe-putty powder enganyangekiyo emanzini, esetyenziswa ngokubanzi kwintsimi yokwakha.
I-putty-resistant powder powder yi-adhesive esetyenziselwa ukwakha izakhiwo zokuzalisa izikhewu, iintanda kunye nemingxuma kwiindonga, i-samente, ikhonkrithi, i-stucco kunye nezinye iindawo.Isetyenziswa ikakhulu ukwenza umphezulu ogudileyo wokupeyinta, ukwenza iphepha lodonga okanye ukuthayela.I-putty powder enganyangekiyo emanzini ibonwa kakhulu ngenxa yokukwazi ukumelana nokufuma, okwenza kube yinto efunekayo kumagumbi okuhlambela, iikhikhini kunye nezinye iindawo ezimanzi.
Kukho iingenelo ezininzi zokusebenzisa i-HPMC kumgubo onganyangekiyo wamanzi.
I-HPMC yi-ejenti egqwesileyo yokugcina amanzi, enokuphucula ukusebenza kwe-repellent yamanzi esetyenziswa ngokuqhelekileyo kwi-putty powder.Ikwanceda ukuthintela ukufuma ekungeneni kwi-putty ukuze kugqitywe ixesha elide, ixesha elide.Ukongeza, i-HPMC yifilimu yangaphambili eyenza umqobo okhuselayo kumphezulu we-putty, ukuthintela amanzi ukuba angangeni kwaye enze umonakalo.
Enye inzuzo ye-HPMC kwi-putty enganyangekiyo emanzini kukuphucula amandla ebhondi ye-putty kunye nokuphucula ukunamathela kwayo kwi-substrate.Le propati yenza i-HPMC isithako esibalulekileyo kwi-putty formulations, ukuqinisekisa ukuba i-putty ibambelela ngokuqinileyo kumphezulu kwaye ayiqhekeki okanye iqhume ngokuhamba kwexesha.Ngokudityaniswa kwe-HPMC, iiputty ezinganyangekiyo ngamanzi zizinza ngakumbi, zomelele kwaye zisebenziseka lula, nto leyo ezenza zibe lukhetho oludumileyo phakathi kweengcali zokwakha.
Ukongeza kwiimpawu zayo zokugxotha amanzi, i-HPMC nayo inempembelelo enenzuzo kwimpembelelo yendalo ye-putty enganyangekiyo emanzini.Ubume bayo be-biodegradable buqinisekisa ukuba i-putty ihambelana nokusingqongileyo kwaye ayonakalisi indalo.I-HPMC nayo ayinayo ityhefu kwaye ayivelisi nayiphi na imisi eyingozi okanye ivumba, iyenza ikhuseleke ukuba isetyenziswe kwizakhiwo nakwizindlu.
Ukusetyenziswa kwe-hydroxypropyl methylcellulose (HPMC) kwi-putty-resistant powder powders yinto ebalulekileyo kwishishini lokwakha.Iimpawu zayo ezingenakunqanda amanzi kunye ne-adhesive zenza ukuba ibe yinto ebalaseleyo kwi-putty, inika ukugqiba ixesha elide, eliqinileyo elichasayo ukufuma kunye nokusingqongileyo.Ngaphezu koko, iyonakaliswa kwaye ayinayo ityhefu, iyenza ibeyenye indlela yokusingqongileyo ekhuselekileyo ukuba isetyenziswe kwiindawo zikawonke-wonke.Ngokusebenzisa i-HPMC, sinokwakha izakhiwo ezinokuqina okukhulu, ukuzinza kunye nokuzinza.
