Labada hydroxypropyl methylcelrelose iyo hydroxyetyl ​​cellulose cellulose waa cellose, waa maxay farqiga u dhexeeya labada?

01
HPMC iyo HEC
Hydroxypropyl methylcelrellose (Hypromellose), oo sidoo kale loo yaqaan hypromellose, waa nooc ka mid ah unugyada unugyada in-onic-ka ee ether ah. Waa polyter semisis-ka, firfircoon, poly peymer peyms plomy ah oo caadi ahaan loo isticmaalo saliidaha ophthalmology, ama sida ku-meel-gaadhka ah ama gaari ku jira dawooyinka afka.
Kariimka hydroxyetyl ​​(HEC), qaaciddada kiimikada (c2H6o2) n, waa huruud cad ama khafiif ah, oo aan sun lahayn oo ka kooban unugyada alkaline iyo budada ah (ama chlorotheeranol) waxaa lagu diyaariyaa etheral-ka oo ay iska leeyihiin anshax-gacmeedyada aan lagu milmin. Sababta oo ah HEC waxay leedahay guryo wanaagsan oo ah qaro weyn, oo laga joojinayo, kala-baxa, isku-darka, sameynta daadadka, oo loo adeegsado polympire-ka, xaashiyaha, oo ah polymer polymping-ka, 40 qiimayaasha mehelka ah ≥ 99%.

02
kala duwansho
In kasta oo labaduba ay yihiin unugyada unugyada, waxaa jira farqiyo badan oo u dhexeeya labada:
Hydroxypropyl methylrcellellase iyo hydroxyeterylcellellase ayaa ku kaladuwan guryaha, isticmaalka, iyo laqalka.

1. Astaamaha kala duwan
Hydroxypropyl methylcelrelose: (HPMC) waa cadaan ama fiber cad ama budo leh, oo ka tirsan unugyada unugyada kala duwan ee aan isku qasan. Waa poly-symi-symthetic poly polyver-ku-noolaansho.
Hydroxyethylcellosure: (HEC) waa mid cad ama jaalle ah, fiber aan lahayn ama fiber adag ama budo adag. Waxaa ka mid ah by alkaline cellulose iyo oxide oxide (ama chlorohrinindrin). Waxay ka tirsan tahay unugyada aan ion-ethules notlululle ether.

2. Xoolaha kala duwan
Hydroxypropyl methylcelrellose: ku dhawaad ​​oo aan ku dhexjiro ethanol-ka, ethet iyo acetone. Xal-xumo cad ama xoogaa daruur ah oo daruuri ah ayaa lagu kala diri karaa biyo qabow.
Kariimka hydroxyetyl: Waxay leedahay astaamaha qaro weyn, oo la joojinayo, xirashada, emul, kala firidhsan, kala firidhsan iyo qoyaanka. Waxay u diyaarin kartaa xalka noocyo kala duwan oo muuqaal ah oo leh cusbo aad u fiican oo cusbo fiican u leh electrolytes.
Hydroxypropylkylcellellalose waxay leedahay astaamaha awooda qaro weyn, iska caabin milix hoose, xasilloonida biyaha, xasilloonida biyaha, isu-tagida guud ee qaab-dhismeedka, is-caabbinta sunta ah, kala-duwanaanta iyo wada-noolaanshaha iyo wada-noolaanshaha.

Farqi badan ayaa u dhexeeya labada, iyo waxbarashadooda warshadaha ayaa sidoo kale aad u kala duwan.

Hydroxypropylylulosulose waxaa badanaa loo isticmaalaa sidii dhumuc weyn, kala firidhsan oo lagu xasiliyaa warshadaha dahaarka, oo ay ku leedahay xaamilaad wanaagsan oo biyo ah ama solvents dabiici ah. Wershadaha dhismaha, waxaa loo isticmaali karaa sibidh, gypsum, dheel dheel, malaas, iwm., Iwm., Iwm., Iwm., Iwm., Iwm.
Kariimka hydroxyetyl ​​wuxuu leeyahay astaamaha dhumucda, la joojinayo, xirashada, emul, kala firidhsan, kala firidhsan iyo qoyaanka. Waxay u diyaarin kartaa xalka noocyo kala duwan oo muuqaal ah oo leh cusbo aad u fiican oo cusbo fiican u leh electrolytes. Unugyada hydroxyetyl ​​waa filif wax ku ool ah oo hore, tilifier, dhumuc weyn, ku nasiyey iyo kala firidhsan shampnos, timaha timaha, qaboojiyeyaasha, qaboojiyeyaasha iyo waxyaabaha la isku qurxiyo. Ku-maydhista budada ku jirta dhexda dhexda waa nooc ka mid ah wakiilka dib-u-dhigga wasaqda. Unugyada hydroxytyl waxay si dhakhso leh ugu milmayaan heerkulka sare, kaas oo dardargelin kara geedi socodka wax soo saarka oo uu wanaajin karo waxtarka wax soo saarka. Muuqaalka muuqata ee saabuunta ka kooban hydroxytyl cellulose ayaa ah in ay hagaajin karto sildenimada iyo miisaaniyada dharka.
