Molecule: c2h6o2 xch4o x pheur 2002 wuxuu qeexayaa hyroxyetyl ​​methylcelrelosuse inuu qayb ahaan o-methylaaysan, qayb ahaan o-hydroxymeylase. Faahfaahinta kala duwan waxaa lagu muujiyaa qiimaha muuqaalka muuqaalka muuqaalka ah ee 2% W / v v ab aque aque the 20 ° C, oo cutubkuna waa MPA s.
Miisaanka Moleculal: Pheur 2002 wuxuu qeexayaa hyroxyetyl ​​methylcelrelouse qayb ahaan o-methylated, qayb ahaan o-hydrobymyluse. Faahfaahinta kala duwan waxaa lagu muujiyaa qiimaha muuqaalka muuqaalka muuqaalka ah ee 2% W / v v ab aque aque the 20 ° C, oo cutubkuna waa MPA s.

Astaamaha ugu weyn ee hydroxyetylylrcylrcellersose (hemc) waa:

1. Xabsi: Ku milatari biyo iyo qaarlo dabiici ah oo dabiici ah. Hemc waxaa lagu kala diri karaa biyo qabow. U fiirsashada ugu sarreysa waxaa lagu go'aamiyaa kaliya viscosity. Xalaashku waxay ku kala duwan tahay viscosity. Hoos u dhaca cod-galka, kuwa kor u qaadida jilitaanka.

2. Cilmiga milixda: Alaabada hemc waa anshax-gacmeedyo aan caadi ahayn, sidaa darteedna waxay ku xasilloon yihiin xalka milixda aqueol ah ama isku-darka badan ee tamarta leh, laakiin isku-darka xad-dhaafka ah ee electrolytes ayaa sababi kara grace iyo roobab.

3. Firfircoonaanta dusha sare

4. Qalliinka kuleylka ah: Marka xalka aques-ka ee HEMC 'uu kululeeyo heerkul gaar ah, waxay noqotaa mid opaque, gelsite, laakiin marka si joogto ah loo qaboojiyo, waxay ku soo noqotaa xalka xalka asalka ah, iyo gubashada iyo roobka. Heerkulku wuxuu badiyaa ku xiran yahay saliidaha, ka hakinta aaladda, aruurinta difaaca, emulsifiers, iwm.

5. Xirfadaha dheef-shiid kiimikaad iyo ur hooseeya iyo udgoon: HEMC waxaa si weyn loogu adeegsadaa cuntada iyo dawada maxaa yeelay lama qaadan doono lacag iyo ur hooseeya iyo ur.

6. Cadaadiska cafiska ah: hemc wuxuu leeyahay iska caabin cafiska ah oo wanaagsan iyo xasilloonida aragga ee wanaagsan inta lagu jiro kaydinta muddada-dheer.

7. PH Deganaanshaha

Codsi: hydroxyetylylylylrcellellalose waxaa loo isticmaali karaa wakiilka kahortaga qulqulka, emulsifier iyo firfircoonida iyo kala firidhsan oo ay ugu wacan tahay shaqadeeda firfircoon ee xalka aqueous. Tusaalaheeda codsigeeda waa sida soo socota: Saamaynta ay ku leedahay hydroxyetylylylkyl methylcelrellase ee ku saabsan waxqabadka sibidhka. Hydroxytylylcellcellellalose ma metylcelrenose waa ur, dhadhan la'aan, budo cad oo aan sun lahayn oo lagu kala diri karo biyo qabow si ay u sameeyaan xalka viscous ee hufan si ay u sameeyaan xalka viscous ee hufan si loo sameeyo xalka viscous ee hufan si loo sameeyo xalka viscous ee hufan si loo sameeyo xalka viscous ee hufan si loo sameeyo xalka viscous ee hufan. Waxay leedahay astaamaha dhumucda, kuna firidhsan, kala firidhsan, emulsing, sameynta filimka, oo laga joojinayo, xaraashka, dusha sare, oo kacsan, sii wadida qoyaan iyo ilaalinta codka. Maaddaama xalka aqueous uu leeyahay shaqo dusha sare ah, waxaa loo isticmaali karaa inuu yahay wakiilka kahortaga qulqulka, emulsifier iyo kala firidhsan. Hydroxyetylcellcellelrcellersose xalka aquophicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicicication uuna yahay wakiilka haynta biyaha ee hufan.
