Heerarka Sodium Carboxymethylcellulose/ Polyanionic cellulose

Sodium carboxymethylcellulose(CMC) iyo cellulose polyanionic (PAC) ayaa si weyn loogu isticmaalaa warshado kala duwan sida dhumucyada, xasiliyayaal, iyo beddelayaasha rheology. Si loo hubiyo tayada iyo badbaadada, dhowr heer ayaa loo sameeyay walxahan. Qaar ka mid ah heerarka ugu muhiimsan ee CMC iyo PAC waa:

1. Codex Kiimikooyinka Cunnada (FCC): Kani waa jaangooyooyin uu dejiyay Heshiiska Dawaynta ee Maraykanka (USP) ee maaddooyinka cuntada, oo ay ku jirto CMC. FCC waxay dejisaa jaangooyooyin nadaafadda, aqoonsiga, iyo tayada CMC ee loo isticmaalo codsiyada cuntada.

2. Yurub Pharmacopoeia (Ph. Eur.): Ph. Eur. waa ururinta jaangooyooyinka walxaha dawooyinka laga isticmaalo Yurub. Waxa ku jira hal-ku-dhegyo loogu talagalay CMC iyo PAC, kuwaas oo dejiya shuruudaha tayada iyo nadiifnimada ee walxahan loo isticmaalo codsiyada dawooyinka.

3. Machadka Batroolka Mareykanka (API): API-gu wuxuu dejiyaa heerarka PAC ee loo isticmaalo qodista dareeraha ee warshadaha saliidda iyo gaaska. API-ku wuxuu qeexayaa sifooyinka, waxqabadka, iyo shuruudaha tayada ee PAC ee loo isticmaalo qodista dareeraha.

4. Ururka Caalamiga ah ee Halbeega (ISO): ISO waxay dejisay dhowr heerar oo loogu talagalay CMC iyo PAC, oo ay ku jiraan ISO 9001 (nidaamka maaraynta tayada), ISO 14001 (nidaamka maaraynta deegaanka), iyo ISO 45001 (nidaamka maaraynta caafimaadka iyo badbaadada shaqada).

5. Ururka Farsamada ee Wershadaha Saxarka iyo Warqadaha (TAPPI): TAPPI waxay dejisay heerar loogu talagalay CMC ee loo isticmaalo warshadaha waraaqaha. Heerarkan ayaa qeexaya waxqabadka iyo shuruudaha tayada ee CMC ee loo isticmaalo ku dar warqad ahaan.

Guud ahaan, heerarkani waxay caawiyaan hubinta tayada, badbaadada, iyo joogtaynta CMC iyo PAC ee loo isticmaalo warshado kala duwan. U hoggaansanaanta heerarkan ayaa muhiim u ah soosaarayaasha, alaab-qeybiyeyaasha, iyo isticmaalayaasha dhamaadka si loo hubiyo waxtarka iyo badbaadada alaabtooda.
