I-HydroxypropyTelmethylcelcelcelcelcelcelcebalose (i-HPMC) yindawo ebalulekileyo elubuko, edlala indima ebalulekileyo ekuphuculeni ukusebenza kodaka. Njengeyisilwanyana esinganetyhefu, esingayithengisi kwaye sinobuhlobo, i-HPMC ithathe indawo yongezwa ngokwesiko efana ne-stanch ether kunye ne-lignn ekwina kwishishini lokwakha. Eli nqaku liza kuthetha ngendima ebalulekileyo ye-HPMC kwi-hipmc kwinxalenye emithathu yokugcinwa kwamanzi, ukusebenza kunye nokuthambeka.
I-HPMC inokuphucula ngokufanelekileyo ukugcinwa kwamanzi. Ukugcinwa kwamanzi ku-purser kubhekiswa kumandla okulala ukuze agcine umxholo wayo wamanzi ngexesha lokwakha. Ukugcinwa kwamanzi kunodaka kuhambelana nokusebenza kwesamente kunye nokongezwa kwezinto ezisetyenziswa kudaka. Ukuba udaka lungaphandle, luya kubangela ukuba udaka luphume, oluya kunciphisa kakhulu ukuphuculwa kwayo kunye nokunamathela, kwaye nokubangela iingxaki ezinje ngemveliso egqityiweyo.
I-HPMC iqulethe i-hydroxyl kunye namaqela e-methyl kwaye i-hydrophilic kakhulu. Inokwenza umaleko wefilimu yomphezulu kumphezulu wamasuntswana ofayo ukuthintela ukuvela kwamanzi kwaye kuphucule ngokufanelekileyo ukugcinwa kwamanzi. Kwangelo xesha, i-HPMC inokudibanisa neemolekyuli zamanzi ngokusebenzisa iimolethi ze-hydrogen, zenza kube nzima ngakumbi kwiimolekyuli zamanzi ezahlukahlukana namacangci odaka. Ke ngoko, i-HPMC inefuthe elibonakalayo ekuphuculeni ukugcinwa kwamanzi kodaka.
I-HPMC inokuphucula ukusebenza kodaka. Ukusebenza korhango kubhekiswa kukhululwa luphawu olunokwenziwa ngoobango kwaye lubekwe ngexesha lokwakha. Okungcono ukuphumelela kodaka, kuya kuba lula kubasebenzi bokwakha ukulawula ubume kunye nokungqinelana kodaka ngexesha lenkqubo yokwakha. Ukusebenza okuhle kodaka kunokunciphisa inani leengxowa zomoya kwimveliso egqityiweyo, esenza isakhiwo sincinci kwaye siqinile.
I-HPMC inokuphucula ukusebenza ngokuphumelelayo kodaka ngokunciphisa i-viscosity yodaka. Ubunzima be-MPMC ye-HPMC iphakame, kwaye kulula ukwenza iibhondi ze-hydrogen ngeemolekyuli zamanzi, ezikhokelela kwi-viscofity ephezulu. Nangona kunjalo, i-HPMC inokuhluthwa kumasuntswana amancinci phantsi kwesenzo samandla eShear, ukunciphisa i-viscosity yodaka. Ke ngoko, xa abasebenzi bokwakha baphatha udaka, amasuntswana e-HPMC aya kuqhekezwa, enze ubisi olunodaka kwaye kube lula ukwakha. Ngapha koko, amaqela e-hydrophilic e-HPMC akwazi ukwenza ifilimu yomphezulu kumphezulu wamasuntswana, ukunciphisa uxinzelelo phakathi kwe-TRPATAPle, kwaye uqiniseke ngakumbi ukusebenza kodaka.
I-HPMC inokuphucula ukunamathela kodaka. Ukunamathela kodaka kubhekiswa kubuchule bayo bokulandela ngqo kumphezulu wesithamo. Unxibelelwano oluhle lunokwenza uqhagamshelo oluqinileyo noluthembekileyo phakathi kodaka kunye nomhlaba, uqinisekisa ukuqina kwemveliso egqityiweyo. Ukongeza, i-adheion elungileyo inokwenza umphezulu wemveliso egqityiweyo inyibilikisi kwaye intle kakhulu.
I-HPMC inokuphucula ukunamathela kodaka ngeendlela ezininzi. Okokuqala, i-HPMC inokwenza ifilimu yomphezulu kumphezulu womhlaba olandelayo emva kokwakha umhlaba, onokuthi unciphise ukungqubana komphezulu womhlaba kwaye kwenza kube lula ukuba udaka lubambelele kwindawo enodaka. Okwesibini, amasuntswana e-HPMC anokwenza ubume benethiwekhi kumphezulu we-subsest, bonyusa indawo yoqhakamshelwano phakathi kodaka kunye nomhlaba, kwaye phucula ngakumbi ukunamathela kodaka. Ngapha koko, amaqela e-hydrophilic kwi-HPMC anokudityaniswa neemolekyuli zamanzi, ezinokuthi zandise ngokufanelekileyo umyinge wamanzi omdaka kwaye phucula ngakumbi amandla okuzala.
Ukusetyenziswa kwe-HPMC kudaka kuneengenelo ezininzi ezinjengokugcina amanzi, ukusebenza, kunye nokuphuculwa okunamanzi. Ezi zibonelelo azizukuxhamla kuphela abasebenzi bokwakha, kodwa zinempembelelo entle kumgangatho wemveliso egqityiweyo. Ngophuhliso lwesayensi kunye netekhnoloji, kukholelwa ukuba i-HPMC iza kudlala indima ebaluleke kakhulu kwishishini lokwakha kwaye ibonelele ngezinto ezisebenzayo nezikhuselekileyo zeshishini lokwakha.
