Methyl-Hydroxyethylcellulose | CAS 9032-42-2

Methyl Hydroxyethylcellulose (MHEC) ndi chochokera ku cellulose ndi formula yamankhwala (C6H10O5)n. Amachokera ku cellulose, polima yopezeka mwachilengedwe yomwe imapezeka m'makoma a cellulose. MHEC imapangidwa kudzera mu kusintha kwa mankhwala a cellulose, ndikuyambitsa magulu onse a methyl ndi hydroxyethyl pamsana wa cellulose.

Nazi mfundo zazikulu za Methyl Hydroxyethylcellulose:

1. Kapangidwe ka Mankhwala: MHEC ndi polima yosungunuka m'madzi yokhala ndi mawonekedwe ofanana ndi a cellulose. Kuphatikizika kwa magulu a methyl ndi hydroxyethyl kumapereka mawonekedwe apadera ku polima, kuphatikiza kusungunuka kwamadzi m'madzi komanso kukulitsa luso lakukula.
2. Katundu: MHEC imawonetsa kukhuthala bwino kwambiri, kupanga mafilimu, ndi zomangira, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zosiyanasiyana. Amagwiritsidwa ntchito ngati thickener, stabilizer, ndi viscosity modifier m'mafakitale osiyanasiyana, kuphatikizapo zomangamanga, mankhwala, chisamaliro chaumwini, ndi zokutira.
3. Nambala ya CAS: Nambala ya CAS ya Methyl Hydroxyethylcellulose ndi 9032-42-2. Nambala za CAS ndi zozindikiritsa manambala zapadera zomwe zimaperekedwa kuzinthu zamankhwala kuti zithandizire kuzindikira ndikutsata zolemba zasayansi ndi nkhokwe zowongolera.
4. Mapulogalamu: MHEC imagwiritsa ntchito kwambiri ntchito yomangamanga ngati yowonjezera mumatope opangidwa ndi simenti, zomatira za matailosi, ndi zipangizo za gypsum. M'zamankhwala ndi zinthu zosamalira anthu, zimagwiritsidwa ntchito ngati zomangira, zomangira filimu, komanso zosintha ma viscosity mu zokutira zamapiritsi, ma ophthalmic solution, mafuta opaka, mafuta odzola, ndi ma shampoos.
5. Mkhalidwe Woyang'anira: Methyl Hydroxyethylcellulose nthawi zambiri imadziwika kuti ndi yotetezeka (GRAS) kuti igwiritsidwe ntchito m'mafakitale osiyanasiyana. Komabe, zofunikira pakuwongolera zitha kusiyanasiyana kutengera dziko kapena dera lomwe akugwiritsidwa ntchito. Ndikofunikira kutsatira malamulo ndi malangizo oyenera popanga zinthu zomwe zili ndi MHEC.

Ponseponse, Methyl Hydroxyethylcellulose ndiwochokera ku cellulose yosunthika yokhala ndi zinthu zamtengo wapatali pazogwiritsa ntchito zosiyanasiyana zamafakitale ndi zamalonda. Kuthekera kwake kupititsa patsogolo mawonekedwe a rheological of formulations kumapangitsa kukhala chisankho chokondedwa kuti mukwaniritse zomwe mukufuna kuchita pazinthu zosiyanasiyana.
