Ngaba izityalo ze-HPMC zisekwe?

I-HydroxyPOpyl Methylcelcellulose (HPMC) yindawo esetyenziswa kakhulu kumashishini ahlukeneyo, ukusuka kumachiza amayeza ukuya kwiimveliso zokutya kwizixhobo zokwakha. Ukusetyenziswa kwayo kunye nokusebenza kwayo kunye nokusebenza kwayo kwenza ukhetho oluphakathi luluhlu olubanzi lwezicelo. Umbuzo omnye osoloko uvela kukuba i-HPMC isekwe kwi-SITMC okanye isuswe kwimithombo yesilwanyana.

1.Omigins ye-HPMC:
I-HPMC yi-polymer ye-semi-synthemetic ethathwe kwi-sellyulose, eyenzeka ngokwemvelo iPolysaccharide efumaneka kwiindonga zeseli. I-seluplose uqobo iqulunqwe ekuphindaphinda i-Glucose idityaniswe kunye, yenza amakhonkco omde. I-HPMC ifunyenwe ngokuguqulwa kweekhemikhali kweselphulelo, ngokukodwa ngokufakwa endaweni yamaqela e-hydroxyl nge-FOSTASXY kunye namaqela e-hydroxypropy.

2. Inkqubo yokuveliswa:
Ukuveliswa kwe-HPMC kubandakanya amanyathelo aliqela, ukuqala ngokukhupha i-selsulose ukusuka kwimithombo yezityalo efana nokupeyinta iinkuni okanye i-cotton ezinerters. Nje ukuba ikhutshiwe, i-seluplose iphantsi kohlengahlengiso lwekhemikhali ukuze ikwazise amaqela e-hydroxypropy kunye namaqela e-AMAFISY. Le nkqubo ibandakanya unyango kunye ne-alkali, ilandelwa sisisori usebenzisa i-propylene oxide kunye ne methyl chloride.

Ngexesha lokuthengiswa, amaqela e-hydroxypropy aziswa ukunika ukubethwa kwamanzi kunye nezinye iipropathi ezinqwenelekayo kwimolekyuli. Amaqela ka-Accords, kwelinye icala, anegalelo kuzinzo olupheleleyo kunye novimba we-viscosity ye-HPMC. Inqanaba lokufakwa endaweni (DS) le-hydroxypropy kunye namaqela e-AFDISS anokulawulwa ukulandela iipropathi ze-HPMC yezicelo ezithile.

Umzekelo osekwe kwi-HPMC:
Ngenxa yokuba i-HPMC isuselwa kwisellumse, efumaneka kakhulu kwimithombo yezityalo, isekwe ngokweendalo. Izinto eziphambili zezinto eziphambili ezisetyenzisiweyo kwimveliso ye-HPMC-ye-HPMC kunye ne-Cotton Linter-zivela kwizityalo. Ngokungafaniyo nezinye iipolimers okanye iikopi ezinokufunyanwa kwiimveliso zezilwanyana, ezinjengeGelatin okanye ii-waxes ezithile, i-HPMC ikhululekile kwizithako ezifunekiyo zezilwanyana.

Ngaphaya koko, i-HPMC ihlangabezana neenqobo zokuzithathwa njengezihlobo ze-vegan kunye nezilwanyana ezinobuhlobo, njengoko zingazibandakanya ukusetyenziswa kwezinto ezingafunekiyo izilwanyana okanye izixhobo zokusebenza. Le nkalo ibaluleke ngokukhethekileyo kubathengi abalandela ukutya okusekwe kwizityalo okanye babe neengcinga zokuziphatha malunga nokusetyenziswa kweemveliso zezilwanyana.

Iindlela zokusebenza kunye nezibonelelo:
Uhlobo lwe-HPMC lwe-HPMC lunegalelo lokwamkelwa ngokubanzi kunye nokusetyenziswa kwamashishini ahlukeneyo. Kwicandelo lamayeza, i-HPMC isetyenziswa njengokungafaniyo namayeza kwiifom zomnxeba zomlomo ezifana neetafile, iicaphule, kunye nokumiswa. Ukwazi kwayo ukwenza ii-galls ezizinzileyo, ukulawula ukhuphelo lweziyobisi, kwaye ukuphucula ukwahlulahlulo kwetafile kuyenza isithako esixabisekileyo kwifomu yamayeza.

Kwishishini lokutya, i-HPMC isebenza njenge-thiyicker, i-stabilizer, kunye ne-mulssifier kwiindawo ezahlukeneyo, kubandakanya iimpahla ezibhakiweyo, ezinye iindlela zobisi, iisosi, kunye neziselo. Imvelaphi yayo esekwe kwimvelaphi kunye nemfuno yokukhula kwabathengi yezithako zendalo kunye nezinzileyo kwiimveliso zokutya.

I-HPMC ifumana izicelo kwizixhobo zokwakha, apho isetyenziswa khona njenge-RheOlogy Modifier, iarhente yokugcina amanzi, kwaye inamathela kwiimveliso ezinjengokufa, iiplasters, kunye ne-theives. Indalo yayo esekwe kwisityalo iyenza ukuba ifundela indlela yokwakha indalo yokwakha.

I-HydroxyPOpyl Methylcelcelsele (i-HPMC) yi-polymer eguquguqukayo evela kwi-sellulose, icandelo lendalo leendonga zeseli zezityalo. Inkqubo yayo yemveliso ibandakanya ukutshintsha kwekhemikhali yeselfowuni ekhutshiweyo kwimithombo yezityalo, isenza ukuba ibe yindawo. Ngenxa yoko, i-HPMC ilungele ukusetyenziswa kumashishini ahlukeneyo, kubandakanya amayeza, ukutya, kunye nolwakhiwo, apho kwakhiwa khona imvelaphi yalo yesityalo, apho i-jorenes yayo yokuthathwa kunye nezithako zabathengi zendalo kunye nezinzileyo. Ngokuqonda uhlobo olusekwe kwizityalo ze-HPMC, abavelisi kunye nabathengi ngokufanayo banokwenza ukhetho oluxhasa amaxabiso abo kunye nokuzinza.
