Methyly-hydroxyetylcelleselus | CAS 9032-42-2

Metyl hydroxyethylcellose (MHEC) waa ka-yeelashada unugyada unugyada kiimikada (c6h10o5) n. Waxaa laga soo qaatay celylulose, polymer dabiici ah oo dabiici ah oo laga helo darbiyada unugyada ee dhirta. MHEC waxaa lagu dhex maray wax ka badalida kiimikada ee cellulose, oo ku soo bandhigaya labada methyl iyo kooxo hydroxytyl-ka oo laf-dhabarka laf-dhabarka.

Halkan waxaa ah qodobo muhiim ah oo ku saabsan methyl hydroxyethylcellosuse:

1. Qaab-dhismeedka kiimikada ah: MHEC waa polymer-ku-sicir-biyo-ku-ool ah oo la mid ah qaab la mid ah kan unugyada unugyada. Ku darista methyl iyo veryroxytyl-ka iyo kooxaha hydroxyetyl ​​waxay ka dhigan tahay guryo gaar ah oo loo yaqaan 'polymer', oo ay kujirto salaan hagaagsan oo ku jirta biyaha iyo awoodda qaro weyn ee la wanaajiyey.
2. Guryaha: MHEC ayaa muujinaya qaro weyn oo qaro weyn leh, filim-sameynta, iyo guryaha lagu xidho, taasoo ka dhigeysa mid ku habboon codsiyo fara badan. Waxaa badanaa loo istcimaalaa sidii dhumuc weyn, xasilooni, iyo mowqif viscosity ah ee warshadaha kala duwan, oo ay kujirto dhismaha, dawooyinka, daryeelka shakhsi ahaaneed, iyo jaakadahaaga.
3. Lambarka CAS: Lambarka CAS ee methyl hydroxyethylcellosuse waa 9032-42-2. Lambarada CAS waa aqoonsiyo tiro ahaan oo loo qoondeeyay walxaha kiimikada si loo fududeeyo aqoonsiga iyo raadraaca suugaanta sayniska iyo xog-ururinta sharciyeynta.
4. Codsiyada: MHEC waxay ogaataa adeegsi ballaaran oo ku jira warshadaha dhismaha inay tahay wakiil qaro weyn leh oo ku jira madaafiicda sibidhka ah, iyo agabyada ku saleysan ee ku saleysan. Daawooyinka iyo alaabada daryeelka shakhsi ahaaneed, waxaa loo adeegsadaa inay yihiin laba-geesood, filim hore, iyo mowqif muuqaal ah oo ku jira jaakadaha kiniiniga, xalka indhaha, kareemada, kareemada, iyo shaambada, iyo shaambada, iyo shaambada.
5. Xaaladda sharciyeynta Si kastaba ha noqotee, shuruudaha sharci ee gaarka ah way kala duwanaan karaan iyadoo ku xiran dalka ama gobolka isticmaalka. Waa muhiim in la raaco qawaaniinta iyo tilmaamaha la xiriira marka la dejinayo alaabada ay ku jiraan MHEC.

Guud ahaan, methyl hydroxyethylcellosure waa mid ka mid ah unugyada unugyada isku-darka leh ee guryaha qiimaha leh ee codsiyada warshadaha iyo ganacsi ee fara badan. Awoodda ay u leedahay in lagu wanaajiyo guryaha rheolololojiyada ee qaababka ka dhigaya doorashada la doorbido si loo gaaro astaamaha waxqabadka ee la doonayo ee alaabada kala duwan.
