IHydroxypropyl methylcellulose (HPMC) sisithako esiphambili kwizinto ezininzi zokwakha, kubandakanywa udaka, iiplaster kunye neeplasta. I-HPMC yipolymer esekwe kwiselulosi evela kwimicu yezityalo kwaye ineempawu ezibalaseleyo zokugcina amanzi. Xa yongezwa kwizinto zokwakha ezisekelwe kwi-samente, inika izibonelelo ezininzi, kubandakanywa ukuphuculwa kokusebenza, ukugcinwa kwamanzi kunye nokubambelela. Eli nqaku liza kuphonononga impembelelo entle ye-HPMC kwizinto zokwakha ezisekwe kwisamente kunye nendlela enokuphucula ngayo umgangatho wodaka.
Ukuphucula ukusebenza
Enye yeenzuzo eziphambili ze-HPMC kwizinto zokwakha ezisekwe kwisamente yimpembelelo yayo ekusebenzeni. Ukusetyenzwa kuyipropathi ebalulekileyo yodaka kuba ichaphazela ukukhululeka apho udaka lunokusetyenziswa kwaye lusetyenzwe kwimilo efunwayo. I-HPMC iphucula ukusebenza kodaka ngokunyusa i-viscosity yayo, ngaloo ndlela inqanda ulwahlulo kunye nokwandisa ukuhambelana kodaka. Olu phawu lwenza i-HPMC ibe luncedo ngakumbi xa isebenza ngeemilo ezintsonkothileyo okanye uyilo olufuna usetyenziso oluchanekileyo.
Ukugcinwa kwamanzi
Ugcino lwamanzi yenye ipropathi ebalulekileyo yezinto zokwakha ezisekwe kwisamente, ingakumbi udaka. Ukugcinwa kwamanzi aphezulu kugcina i-mortar i-hydrated kwaye ikhusela ukuba yome ngokukhawuleza, nto leyo inokukhokelela ekuqhekekeni nasekulahlekelweni kwamandla. I-HPMC ineempawu ezigqwesileyo zokugcina amanzi kwaye, xa idityaniswe nodaka, igcina ifumile nakwimeko ezomileyo. Le propati ibaluleke kakhulu kwizicelo zangaphandle, apho ukukhanya kwelanga kunye nomoya kunokubangela ukuba udaka lome ngokukhawuleza. I-HPMC yonyusa ukugcinwa kwamanzi kodaka ngokufunxa nokugcina ukufuma, ngaloo ndlela yandisa inkqubo yokufakwa kwamanzi.
Phucula ukubambelela
Ukunamathela yenye impahla ebalulekileyo yezixhobo zokwakha ezisekelwe kwisamente, ingakumbi udaka. Ukuncamathela kubhekiselele ekukwazini kodaka ukunamathela kumphezulu onikiweyo kwaye ugcine iqhina lawo ngokuhamba kwexesha. I-HPMC iphucula ukunamathela kodaka ngokusebenza njengesixhasi sebhondi, ngaloo ndlela inceda udaka ukuba lunamathele bhetele kumphezulu. Olu phawu luluncedo ngakumbi xa imathiriyeli engafaniyo ifuna ukudityaniswa okanye xa umphezulu ungalingani (njengaxa usebenza ngezitena okanye ilitye).
Phucula ukuqina
Ukuqina yeyona propati ibalulekileyo yezixhobo zokwakha ezisekwe kwisamente, kwaye i-HPMC idlala indima ebalulekileyo ekwandiseni ukuqina. I-HPMC iphucula ukuqina kwemathiriyeli yokwakha esekwe kwisamente ngokubonelela ngomqobo emoyeni, emanzini, kuthuli nakwezinye izinto ezingcolisayo. Umqobo ukhusela izinto ezisisiseko kwizinto ezinobungozi bokusingqongileyo, ukunciphisa umngcipheko wokubola kunye nokubola. Isithintelo sikwaphucula ukukwazi kwesixhobo ukuxhathisa imozulu, ukukhenkceza nokunyibilika, kunye nemitha yeultraviolet.
Ukuphucula ukuguquguquka
Ukuguquguquka yenye ipropathi ebalulekileyo yezinto zokwakha ezisekelwe kwisamente i-HPMC enokunceda ukuphucula. Ukuba bhetyebhetye kubhekiselele kubuchule besixhobo sokuziqhelanisa nokutshintsha kobushushu kunye nokufuma, okunokubangela ukwanda okanye ukucutheka. I-HPMC yandisa ukuguquguquka kodaka ngokwenza ifilimu eguquguqukayo ebusweni bezinto eziphathekayo, ivumela ukuba ihambe ngaphandle kokuqhekeka. Olu phawu lubaluleke kakhulu kwiindawo apho ukwandiswa okanye ukudibanisa amajoyina kunokubangela ukuba izinto eziphathekayo ziqhekeke.
ukuququmbela
I-HPMC idlala indima ebalulekileyo ekuphuculeni umgangatho wezinto zokwakha ezisekelwe kwisamente, ngakumbi udaka. Iphucula ukwakhiwa, ukugcinwa kwamanzi, ukuncamathelisa, ukuguquguquka kunye nokuqina, oko kuyenza ibe yinxalenye ebalulekileyo yolwakhiwo lwangoku. Ngaphaya koko, ukusetyenziswa kwe-HPMC kwizinto zokwakha kunegalelo kwimisebenzi yokwakha ezinzileyo njengoko iphucula ukusebenza kwemathiriyeli kwaye inciphisa umngcipheko weempembelelo ezimbi zokusingqongileyo. Ke ngoko, ishishini lokwakha kufuneka liqhubeke nokucofa amandla e-HPMC ekuphuculeni umgangatho wezinto zokwakha ezisekwe kwisamente.
