Hydroxypropyl methylcelculose (hpmc)Ngaba i-sellese ebalulekileyo ye-ether isetyenziswe ngokubanzi isetyenziswa kakhulu kwizinto zokwakha, ngakumbi kwizifakelo ezisekwe kwisamente, izixhobo ezisekwe kwi-gypsim kunye neengubo. I-HPMC idlala indima ebalulekileyo ekuphuculeni iipropathi zodaka, kubandakanya ukuphucula iipropathi zayo zokuphuma emanzini.
1. Phucula ukugcinwa kwamanzi kodaka
Enye yezona zinto zimangalisayo ze-HPMC ngumthamo wayo ofanelekileyo wokugcina amanzi. Ukongeza i-HPMC kudaka kunokuba kukunciphisa kakhulu inqanaba lokulahleka kwamanzi kudaka. Umsebenzi othile:
Yandisa i-quation hydration yexesha lokuphendula: i-HPMC inokugcina umswakama ofanelekileyo ngaphakathi kodaka, kwaye iqinisekise ukuba amasuntswana ethutyana asabele ngokupheleleyo ngamanzi ukwenza imveliso ye-highr.
Ithintela ukwenziwa kwee-rocks: Ukuphulukana namanzi ngokukhawuleza kunokubangela ukuba udaka lunciphise kwaye uqalise i-microcks, ngaloo ndlela kuncitshiswa iipropathi zokwenza amanzi.I-HPMCUnokucothisa ilahleko yelahleko yamanzi kunye nokunciphisa imingxunya ebangelwe kukuntywila.
Ukuphuculwa kokugcinwa kwamanzi kwenza isakhiwo sangaphakathi sesingqengqelo, kunciphisa ukutyeba, kunye nokuphucula ubukhulu becala ukungafezeki kodaka, ngaloo ndlela kuphuculwe ukusebenza kwamanzi.
2. Ukuphucula ukusebenza kodaka
Iimpawu ze-viscosity ze-HPMC ziphucula iipropathi ze-rihlooc zodaka, ngaloo ndlela ziphucula ukusebenza.
Ukucutha ukopha ukopha: i-HPMC inokusasaza amanzi ngokulinganayo, ivumela amanzi ukuba asasazwe ngokuthobekileyo kudaka kunye nokunciphisa iipores ezibangelwa kukwahlulwa kwamanzi.
Ukuphucula ukunamathela kodaka: I-HPMC iphucula amandla aphezulu phakathi kodaka kunye nezinto ezisezantsi, zivumela umphezulu wezinto ezisisiseko ungene kumgangatho ophakathi kwento ephantsi kunye nodaka .
Ukuphuculwa komgangatho wokwakha kuchaphazela ngqo isiphumo sokuphola kwamanzi. I-iyunifomu kunye ne-Deese Coble Gubter inokuthintela ngokufanelekileyo ukungena komswakama.
3. Yenza ifilimu yokukhusela umphezulu
I-HPMC ineepropathi ezibonisa ifilimu kwaye inokwenza ifilimu ecekeceke kwaye ikhuselekile kumphezulu wodaka:
Ukucutha inqanaba lokukhutshwa kwamanzi: Emva kokwakhiwa kwe-HPMC, i-HPMC iya kwenza ifilimu yokukhusela kumphezulu woludaka ukuba inciphise ukunyanzelwa komswakama ngaphakathi komswakalo ngaphakathi.
Ibhlokhi yokungena komswakama: I-HPMC ye-HPMC emva kokuqulunqwa kwefilimu inesidanga esithile sokungaphantsi kwaye sinokusetyenziswa njengesithintelo ukuthintela umswakama wangaphandle ukuba angangeni emanzini.
Olu nyulo luphezulu lubonelela ngokhuseleko olongezelelekileyo lokufumana amanzi odaka.
4. Nciphisa i-perosity yodaka
I-HPMC inokuphucula ngokufanelekileyo ulwakhiwo lodaka. Indlela yayo yesenzo imi ngolu hlobo lulandelayo:
Isiphumo sokugcwalisa: Iimolekyuli ze-HPMC zinokungena kwimozulu ye-microparough kodaka kwaye ngokuyinxenye ziyagcwalisa iipores, ngaloo ndlela kuncitshiswa amajelo omswakama.
Ukuphucula ukungcola kweemveliso ze-hydimer: ngokugcina amanzi, i-HPMC iphucula ukufana nokudityaniswa kweemveliso ze-qumes zesamente kwaye kunciphisa inani leepores ezinkulu kudaka.
Ukuncitshiswa kwesiphimo sokungasebenzi akuphumi kuphela ukusebenza kwamanzi, kodwa kukuphucula ukuqina kodaka.
5. Ukuphucula ukumelana neqhwa kunye nokuqina
Ukungena kwamanzi kuya kubangela ukuba udaka luphathelele ngenxa ye-rost ye-rostfing kwindawo yobushushu ephantsi. Iziphumo ezinamanzi ze-HPMC zinokunciphisa ukungena kwamanzi kwaye zinciphise umonakalo obangelwe yimijikelezo ye-freeze-thaw:
Thintela ukugcinwa komswakama: ukunciphisa ukugcinwa kwemasakali ngaphakathi kodaka kunye nokunciphisa umphumo weqabaka.
UBomi ongezelelweyo ongezelelweyo: ngokunciphisa uhlaselo lwamanzi kunye nomonakalo we-freeze-thaw, i-HPMC yonyusa isifo sexesha elide sodaka.
I-HPMC iphucula intsebenzo yamanzi yodaka malunga nemiba elandelayo: Ukuphucula ukugcinwa kwamanzi, ukuphucula ukusebenza kwamanzi, ukwenza ifilimu, ukwenza ifilimu yokukhusela, ukunciphisa ukukhohlisa iqabaka. Iziphumo ezinamanyala zezi propati zinceda udaka ukuba lubonise iziphumo ezilungileyo zokwenza amanzi kwizicelo ezisebenzayo. Nokuba kusemanzini amanzi afakelweyo, izikrweli ze-fers okanye izikrweqe zeTile, i-HPMC idlala indima ebalulekileyo.
Kwizicelo ezisebenzayo, isixa se-HPMC songezwe kufuneka sibe selungelelene ngokweemfuno ezithile ukuqinisekisa ukuba ayinakukwazi ukwenza isiphumo esihle kakhulu, kodwa ikwagcine ibhalansi yenye izalathiso zodaka. Ngokusetyenziswa kwe-HPMC, ukusebenza kwamanzi kwezinto zokwakha kunokuphuculwa kakhulu kwaye ukhuseleko oluthembekileyo lunokubonelelwa kwiiprojekthi zokwakha.
