Ndozi nke hydroxyethythyth cellulose

Ndozi nkeHydroxyethyth Celluse(HEC) gụnyere usoro akụrụngwa iji meziwanye ịdị ọcha ya, na-agbanwe agbanwe, na-agbanwe agbanwe, na akụrụngwa maka ngwa ndị akọwapụtara. Nke a bụ nyocha nke usoro ndozi maka hec:

1. Nhọrọ nke akụrụngwa:

Usoro nkwugharị ahụ na-amalite site na nhọrọ nke ịdị elu kululose dị ka akụrụngwa. Enwere ike ịdapụta cellose site na isi mmalite dị iche iche, dịka osisi pulp, akwa akwa, ma ọ bụ ihe ndị ọzọ a na-eme.

2. Ọcha dị ọcha:

Mkpụrụ osisi ahụ dị ọkụ na-aga n'ihu iji wepu adịghị ọcha dịka liminin, himicelllose, na ndị ọzọ na-abụghị sellulosic. Usoro dị ọcha a na-emetụta ịsacha, ịcha ọcha, na ọgwụgwọ ọgwụ iji mee ka ọ dị ọcha nke cellulose.

3. Ekele:

After purification, the cellulose is chemically modified through etherification to introduce hydroxyethyl groups onto the cellulose backbone, resulting in the formation of Hydroxyethyl Cellulose (HEC). Mmeghachi omume nke alkali na-emetụtakarị igwe mmiri alkali na otlene oxide ma ọ bụ ethylene chlorohin.

4..

Na-agbaso ehurtification, ngwakọta mmeghachi omume na-anọpụ iche iji wepu Alkali karịrị akarị ma mezie PH. A na-asacha ngwaahịa na-anọ kpamkpam iji wepu kemịkalụ nke ndị na-emepụta mmiri na ngwaahịa site na mmeghachi omume.

5. Ihe nzacha na ihicha:

A na-enyocha ihe ngwọta a nụchara anụcha ma ọ bụ adịghị ọcha ọ bụla. Mgbe FECTration gasịrị, enwere ike itinye nsogbu nsogbu, ma ọ bụrụ na ọ dị mkpa, wee kpọrọ nkụ iji nweta ntụ ọka ikpeazụ ma ọ bụ ụdị hec.

6. Njikwa dị mma:

N'oge ndozigharị, usoro njikwa dị mma na-emejuputa iji hụ na agbanwe agbanwe agbanwee, ịdị ọcha, na arụmọrụ nke HEC ngwaahịa. Nnwale njikwa dị mma nwere ike ịgụnye nha viscosition, nyocha moleghe nke nyocha, mmiri mgbochi mmiri, na nyocha ndị ọzọ na kemịkal ndị ọzọ.

7. Nkịtị na nchekwa:

Ozugbo a na-ekwughachi ya, a na-etinye ngwaahịa Hec na igbe ma ọ bụ akpa maka nchekwa na njem. Nkwanye nkwakọba kwesịrị ekwesị na-enyere aka icheli hec site na ihe mmeru, mmiri, na gburugburu ebe obibi ndị ọzọ nwere ike imetụta mma ya.

Ngwa:

Nchịkọta hydroxyethyth Cellulose (HEC) na-ahụ ọtụtụ ngwa ọrụ dị iche iche, gụnyere:

• Ihe owuwu: Ejiri ya dị ka Thitener, Mediology Medifier, na Njide Mmiri Njide na Ngwaahịa Ciment, agba, mkpuchi, na adhesives.
• Nlekọta onwe onye na cosmetics: jiri rụọ ọrụ dị ka nke ukwu, kwụsie ike, na ihe nkiri mbụ na lotions, ude, shampoos, na ngwaahịa nlekọta onwe ya.
• Ọ na-eji ọgwụ na-egbu egbu, na-etinye aka na ngalaba mbadamba ọgwụ, capsules, na nkwụsịtụ.
• Nri: Ọrụ dị ka nke ukwu, emulsifier, na mmanye na ngwaahịa nri dị ka sauces, akwa na ngwaahịa mmiri ara ehi.

Nkwubi:

Revients nke hydroxyethythythythythythythythythythyths cellulose (HEC) na-agbagha ma sachapụ polymer pollilel, nke na-ebute ihe dị iche iche na-arụ ọrụ dị ka iwu, nlekọta ọgwụ, na nri. Usoro nkọcha ahụ na-eme ka ị na-ahụ na nha anya, ịdị ọcha, na ogo nke Hec, na-enyere ya aka n'ụdị usoro na ngwaahịa.
