Methyl-Hydroxyethylcellulose | CAS 9032-42-2

Methyl Hydroxyethylcellulose (MHEC) waa nooc ka mid ah cellulose oo leh qaacidada kiimikada (C6H10O5)n. Waxaa laga soo qaatay cellulose, oo ah polymer dabiici ah oo laga helo derbiyada unugyada dhirta. MHEC waxaa lagu sameeyaa iyada oo loo marayo wax ka beddelka kiimikada ee cellulose, iyadoo la soo gelinayo labada kooxood ee methyl iyo hydroxyethyl laf-dhabarta cellulose.

Halkan waxaa ah dhowr qodob oo muhiim ah oo ku saabsan Methyl Hydroxyethylcellulose:

1. Qaab-dhismeedka Kiimikada: MHEC waa polymer-ka biyaha ku milma oo leh qaab-dhismeed la mid ah kan cellulose. Ku darista kooxaha methyl iyo hydroxyethyl waxay siisaa sifooyin gaar ah polymer-ka, oo ay ku jiraan milmida biyaha oo la hagaajiyay iyo awoodda dhumucda oo la xoojiyay.
2. Astaamaha: MHEC waxay muujisaa sifooyin aad u fiican oo dhumuc weyn, sameynta filimada, iyo isku xidhka, taasoo ka dhigaysa mid ku habboon codsiyo badan. Waxaa si caadi ah loogu isticmaalaa sidii wax ka beddele dhumuc weyn, xasiliya, iyo wax ka beddele dheellitirka warshadaha kala duwan, oo ay ku jiraan dhismaha, daawooyinka, daryeelka shakhsi ahaaneed, iyo dahaarka.
3. Lambarka CAS: Lambarka CAS ee Methyl Hydroxyethylcellulose waa 9032-42-2. Lambarrada CAS waa aqoonsiyo tirooyin gaar ah oo loo qoondeeyay walxaha kiimikada si loo fududeeyo aqoonsiga iyo la socodka suugaanta sayniska iyo xogta sharciyeynta.
4. Adeegsiga: MHEC waxay si ballaaran ugu isticmaashaa warshadaha dhismaha sidii wakiil dhumuc leh oo ku jira hoobiyeyaal ku salaysan sibidhka, dhejisyada taayirada, iyo walxaha ku salaysan gypsum. Daawooyinka iyo alaabada daryeelka shakhsi ahaaneed, waxaa loo isticmaalaa sidii binder, filim hore, iyo wax ka beddele viscosity ee dahaarka kiniiniga, xalalka indhaha, kareemada, looshinnada, iyo shaambooyada.
5. Xaaladda Sharciyeynta: Methyl Hydroxyethylcellulose guud ahaan waxaa loo arkaa mid ammaan ah (GRAS) oo loogu talagalay isticmaalka loogu talagalay warshadaha kala duwan. Si kastaba ha ahaatee, shuruudaha sharciyeynta gaarka ah way kala duwanaan karaan iyadoo ku xiran waddanka ama gobolka la isticmaalo. Waa lagama maarmaan in la raaco xeerarka iyo tilmaamaha khuseeya marka la samaynayo alaabada ay ku jiraan MHEC.

Guud ahaan, Methyl Hydroxyethylcellulose waa nooc ka mid ah cellulose oo leh sifooyin qiimo leh oo loogu talagalay codsiyo kala duwan oo warshadeed iyo ganacsi. Awooddeeda ay ku horumarin karto sifooyinka rheological ee qaacidooyinka ayaa ka dhigaysa doorasho la doorbidayo si loo gaaro astaamaha waxqabadka la doonayo ee alaabada kala duwan.
