Hydroxypropyl methyl seluplose nekhabhathi ye-carboxethyl sedium can ixutywe

I-Hydroxypropyl Methyl Selelise (HPMC) kunye ne-carboxeymethyl sedium (CMC) Zimbini iindlela ezisetyenzisiweyo zeselsulose kumashishini ahlukeneyo ngenxa yepropathi yabo eyahlukileyo kunye nokusebenza. Ngelixa zombini ziipollymes ezisekwe seselfowuni, zahlukile kwisakhiwo sabo sekhemikhali kunye neepropathi, ezibenza bazilungele izicelo ezahlukeneyo. Nangona kunjalo, kwezinye iimeko, banokuxubungulwa ukufezekisa iimpawu ezithile zomsebenzi okanye ukonyusa iipropathi ezithile zemveliso yokugqibela.

I-HydroxyPOpyl Methyl Selelose (HPMC), ekwabizwa ngokuba yi-hypromellose, yi-ion-ionsulose ether ethathwe kwi-polymer yendalo. Ihambelana nokuphendula kwe-alkali selsulose nge-propylene oxide ne methyl chloride. I-HPMC isetyenziswa ngokubanzi kwiindawo zamayeza, izixhobo zokwakha, iimveliso zokutya, kunye ne-cosmetics ngenxa yokwakha ifilimu yayo ebalaseleyo, ukuqina, ukubopha, kunye nokubopha kwabo. I-HPMC iyafumaneka kumabakala ohlukeneyo kunye namanqanaba ohlukeneyo e-viscofity, evumela ukusetyenziswa kwayo kuluhlu olubanzi lwezicelo.

Kwelinye icala, i-carboxeyymethyl sedium ye-sodium (CMC) i-aionic ye-aionic ye-aionese efunyaniswayo efunyenwe yimpendulo ye-sellulose ene-sodium hydroxide ne-chlorocetic acid. I-CMC yaziwa ngomthamo wokugcina amanzi aphezulu, ubuchule bokwenzela iifilimu, kunye nozinzo kuluhlu olubanzi lweemeko ze-ps. Ifumana izicelo kwiimveliso zokutya, amayeza, cosmetics, iincwadana, kunye nemveliso yephepha ngenxa yokungahambi kakuhle kunye ne-biccomatise.

Ngelixa i-HPMC kunye ne-CMC yabelana ngeepropathi ezithile ezinjengokungathobeli kwamanzi kunye nobuchule bokwenza ifilimu, babonisa iimpawu ezahlukeneyo ezibenza balungele izicelo ezithile. Umzekelo, i-HPMC ikhetha kwiifomu zamayeza ezifana neetafile kunye neecapbules ngenxa yepropathi yokukhutshwa kwayo kunye nokuhambelana nezithako ezisebenzayo zamayeza. Kwelinye icala, i-CMC isetyenziswa rhoqo kwiimveliso zokutya ezinje ngeesosi, ukunxiba, kunye nezinto ezibhakiweyo njengearhente yokuthambisa kunye nokuzinzisa.

Ngaphandle kohluko kwabo, i-HPMC kunye ne-CMC inokudityaniswa kunye kwifomu ethile yokufezekisa iimpembelelo ze-rynerganes okanye ukonyusa iipropathi ezithile. Ukungqinelakwa i-HPMC kunye ne-CMC kuxhomekeke kwizinto ezininzi ezinje ngesakhiwo sabo sekhemikhali, ubunzima bemolekyuli, isidanga sokufaka kunye nemveliso oyifunayo yemveliso yokugqibela. Xa uxutywe kunye, i-HPMC kunye ne-CMC inokubonakalisa ukuqina, ukubopha, kunye neempawu zokwenza ifilimu xa kuthelekiswa nokusebenzisa i-polymer yedwa.

Isicelo esinye esiqhelekileyo sokuxuba i-HPMC kunye ne-CMC sikwinkqubo ye-hydrogel esekwe kwi-hydrogel. I-hydrogels i-Shydrogels zendlela ezintathu zenethiwekhi ekwaziyo ukufumana nokugcina izixa ezikhulu zamanzi, zibenza balungele izicelo ezikhutshelwe iziyobisi. Ngokudibanisa i-HPMC kunye ne-CMC kwimilinganiselo efanelekileyo, abaphandi banokulungelelanisa iipropathi ze-hydrogels ezifana nokudumba, ukomelela koomatshini, kunye nokukhupha ii-kinetics zokukhuphela iimfuno ezithile.

Olunye ukusetyenziswa kokuxuba i-HPMC kunye ne-CMC ikulungiselelwa iipende ezisekwe emanzini kunye neengubo. I-HPMC kunye ne-CMC zihlala zisetyenziswa njengezicubus ze-curiber kunye neemodyuli ze-gemology kwiipeyinti ezisekwe emanzini ukuphucula iipropathi zazo, ezinje ngobugqwirha, ukunganyangeki kwe-SAG, kunye nokunganyangeki kwe-SAG, kunye nokunganyangeki kwe-SAG, kunye nokunganyangeki kwe-SAG, kunye nokunganyangeki kwe-SAG, kunye nokunganyangeki kwe-SAG, kunye nokunganyangeki kwe-SAG, kunye nokunganyangeki kwe-SAG, kunye nokunganyangeki kwe-SAG, kunye nokunganyangeki. Ngokuhlengahlengiswa komyinge we-HPMC ukuya kwi-CMC, iifomulators zinokufezekisa i-viscofity enqwenelekayo kunye nokuhamba kwepeyinti ngelixa ugcina uzinzo kunye nokusebenza kwawo ixesha elide.

Ukongeza kumachiza amachiza kunye nemveliso, imixube ye-HPMC kunye ne-CMC ikwasetyenziswa kumzi-mveliso wokutya ukuphucula ukuthungwa, uzinzo, kunye nomlomo weemveliso ezahlukeneyo zokutya. Umzekelo, i-HPMC kunye ne-CMC zixhaphake kakhulu kwiimveliso zobisi ezifana ne-yogurt kunye ne-ice cream njengabazinzi bokuthintela ukwahlulwa kwenqanaba lokwahlula iSigaba sokwahlula iSigaba sokuthintela iSigaba sokwahlulahlula iSigaba seSigaba seSigaba kunye nokuphucula ukunyamezelana. Kwimpahla ebhakiweyo, i-HPMC kunye ne-CMC inokusetyenziswa njenge-Doulerioners zokuphucula iipropathi ze-Doudes kunye nokunyusa ubomi beShelsi.

Ngelixa i-hydroxypropyl methyl sellise (i-HPMC) kunye ne-carboxeymethyl sedium (CMC) ziindlela ezimbini ezikhethekileyo zokufezekisa iimpembelelo ezithile zokufezekisa iimpembelelo ze-synergistic okanye ukuphucula iipropathi ezithile. Ukungqinelakwa i-HPMC kunye ne-CMC kuxhomekeke kwimiba eyahlukeneyo efana nesakhiwo sabo sekhemikhali, ubunzima bemolekyuli, kunye neempawu ezifunekayo zemveliso yokugqibela. Ngokukhetha ngocoselelo umlinganiso kunye nokudityaniswa kwe-HPMC kunye ne-CMC, iifomula zinokulungelelanisa iipropathi zazo ukuhlangabezana neemfuno ezithile kwiindawo zamayeza, iimveliso, kunye namanye amashishini.
