Ndikwabwino, cmc kapena hpmc?

Kuti mulingalire bwino ndikuwunika CMC (Carboxymethyl cellulose) ndi hydroxypropyl), tifunika kuganizira za zinthu zina, zowononga, komanso zoyenera zofunikira zosiyanasiyana. Onse a CMC ndi HPMC ndi ma cellulose omwe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo zamankhwala, kuphatikiza, zakudya, zodzola komanso zomangamanga. Iliyonse ili ndi mawonekedwe ake ndi mapindu ake, omwe amatsimikizira kutsimikizika kwawo kwa mapulogalamu enaake.

1. Kuyambitsa kwa CMC ndi HPMC:

Carboxymethyl cellulose (cmc):
CMC ndi ma cellulose osungunuka amadzimadzi ochokera ku cellulose yachilengedwe poyambitsa magulu a carboxymethyl a m'mphepete mwa nyanja. Nthawi zambiri imagwiritsidwa ntchito ngati wothandizira kukula, okhazikika, komanso wosungunulira wamadzi mu mafakitale osiyanasiyana.

Hydroxypropyl methylcellulose (hpmc):
HPMC ndi ma cellulose ena osungunuka amadzi opangidwa ndi kuchiritsa cellulose ndi Propylene oxide ndi methyl chloride. Imapeza mapulogalamu mu mankhwala, chakudya, zodzola, ndi zomangamanga chifukwa cha kukula kwake, kupanga filimu, ndi katundu womanga.

2. Chuma chikufanizira:

Kusungunuka:
CMC: Kusungunuka kwathunthu m'madzi.
HPMC: kusungunuka m'madzi pansi pamikhalidwe, ndikupanga yankho lomveka bwino kapena pang'ono.

Makulidwe:
CMC: imawonetsa mafakisoni okwera ngakhale otsika kwambiri.
HPMC: Mavidiyo amasiyanasiyana malinga ndi kuchuluka kwa zolowa m'malo mwazowonjezera.

Katundu wopanga makanema:
CMC: kuthekera kochepa mafilimu.
HPMC: Katundu wopangidwa bwino kwambiri, ndikupanga kukhala koyenera kugwiritsa ntchito ngati zokutira ndi mafilimu.

Kukhazikika kwa matenthedwe:
CMC: Nthawi zambiri kutsika kwa matenthedwe poyerekeza ndi HPMC.
HPMC: imawonetsa bwino matenthedwe, ndikupangitsa kukhala koyenera kwa mapulogalamu apamwamba kwambiri.

3.Pestictions:

Mapulogalamu a CMC:
Makampani ogulitsa zakudya: ogwiritsidwa ntchito ngati wothandizira kukula, okhazikika, ndi chinyezi chosungiramo zinthu ngati mafumu, zovala, ndi mkaka.
Mankhwala ogulitsa: olemba ma piritsi ngati chingwe ndi kuwonongeka.
Zogulitsa Zaumwini: Zopezeka mu mano, mafuta, mafuta odzola, komanso zodzola ngati thiccener ndi kukhazikika.
Kubowola Mafuta: Kugwiritsa ntchito madzi amadzimadzi kuti athetse ma viccction ndi kutaya kwamadzi.

Ntchito za HPMC:
Makampani omanga: Kugwiritsa ntchito matope a simenti, ma plaksters, ndi tiles kuti musangalale komanso kutsatira.
Makampani ogulitsa mankhwala: olemba ntchito zovomerezeka - zotulutsa za mankhwala omasulira, mapiritsi a Prinet, ndi Ophthalmic.
Makampani ogulitsa zakudya: ogwiritsidwa ntchito ngati thicker, emulsifier, ndi kusungunuka muzogulitsa ngati katundu wophika ndi mkaka.
Zodzikongoletsera: zopezeka muzogulitsa ngati shampoos, zonona, komanso zotupa monga wothandizira kukula ndi kanema wakale.

4. Ubwino ndi Zovuta:

Ubwino wa CMC:
Kusungunuka kwamadzi ambiri.
Bwino kwambiri ndikukhazikika.
Mtengo wokwera.
Ntchito yosiyanasiyana m'mafakitale osiyanasiyana.

Zovuta za CMC:
Luso loperewera.
Kukhazikika kwa kutentha komwe poyerekeza ndi HPMC.
Itha kuwonetsa kusinthasintha malinga ndi PH ndi electrolyte ndende.

Ubwino wa HPMC:
Katundu wabwino kwambiri wopanga mafilimu.
Kukhazikika kwamphamvu.
Imapereka zomatira bwino komanso kugwirira ntchito pomanga.
Oyenera kulamulidwa-kumasulidwa kwa mankhwala.

Zoyipa za HPMC:
Mtengo wapamwamba poyerekeza ndi cmc.
Solubility imatha kukhala yosiyanasiyana kutengera kalasi ndikugwiritsa ntchito.
Kusintha kumafuna zida zapadera.

5. Zoyenera kugwiritsa ntchito mapulogalamu ena:

CMC:
Zoyenera kugwiritsa ntchito mapulogalamu omwe amafunikira kusungunuka kwamadzi ndi kukula kwamphamvu, monga chakudya komanso zinthu zosamalira pandekha.
Oyenera kugwiritsa ntchito matenthedwe otsika pomwe kukhazikika kwa marrmal si nkhawa yoyamba.
Kugwiritsidwa ntchito kwambiri pamitundu yosiyanasiyana yomwe imasungunuka mwachangu.

Hpmc:
Amakonda zofunsira zofunikira zopanga mafilimu abwino, monga zokutira ndi mafilimu m'mafakitale opangira mankhwala ndi chakudya.
Zoyenera kugwiritsa ntchito ntchito zomanga chifukwa cha zomata zazikulu kwambiri, kugwirira ntchito, komanso kukhazikika kwamafuta.
Oyenera kugulitsa mankhwala omasulidwa ndi mankhwala osokoneza bongo amafunikira kumasulidwa koyenera kinetics.

6. Kumaliza:

Onse a CMC ndi HPMC ndi ofunika kwambiri pa celluuse omwe ali ndi zinthu zina komanso kugwiritsa ntchito. Kusankha pakati pa CMC ndi HPMC kumadalira zofunikira pazinthu monga kusungunuka, mawonekedwe a mavidiyo, kukhazikika kwa mafilimu, ndi zosowa zamagetsi. Pomwe CMC imapereka madzi osungunuka bwino komanso katundu wabwino kwambiri, HPMC imaposa mapangidwe a filimu, kukhazikika kwa mafilimu, ndi kutsatsa. Kumvetsetsa mawonekedwe apadera a cellulose ndikofunikira posankha chinthu choyenera kwambiri pa ntchito inayake, ndikuwonetsetsa kuti ndi okwera mtengo.
