Methyl-Hydroxyethylcellulose | CAS 9032-42-2

Methyl Hydroxyethylcellulose (MHEC) ndi chinthu chochokera ku cellulose chokhala ndi formula ya mankhwala (C6H10O5)n. Chimachokera ku cellulose, polima wachilengedwe womwe umapezeka m'makoma a maselo a zomera. MHEC imapangidwa kudzera mu kusintha kwa mankhwala a cellulose, zomwe zimapangitsa kuti magulu onse a methyl ndi hydroxyethyl alowe m'malo mwa cellulose.

Nazi mfundo zazikulu zokhudza Methyl Hydroxyethylcellulose:

1. Kapangidwe ka Mankhwala: MHEC ndi polima wosungunuka m'madzi wokhala ndi kapangidwe kofanana ndi ka cellulose. Kuwonjezera magulu a methyl ndi hydroxyethyl kumapereka mawonekedwe apadera ku polima, kuphatikizapo kusungunuka bwino m'madzi komanso kukhuthala kwamphamvu.
2. Katundu: MHEC ili ndi kakulidwe kabwino kwambiri, kupanga filimu, komanso kumangirira, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana. Nthawi zambiri imagwiritsidwa ntchito ngati chowonjezera, chokhazikika, komanso chosinthira kukhuthala m'mafakitale osiyanasiyana, kuphatikizapo zomangamanga, mankhwala, chisamaliro chaumwini, ndi zokutira.
3. Nambala ya CAS: Nambala ya CAS ya Methyl Hydroxyethylcellulose ndi 9032-42-2. Manambala a CAS ndi zizindikiro zapadera za manambala zomwe zimaperekedwa ku zinthu za mankhwala kuti zithandize kuzindikira ndi kutsatira m'mabuku asayansi ndi m'ma database olamulira.
4. Kugwiritsa Ntchito: MHEC imagwiritsidwa ntchito kwambiri mumakampani omanga ngati chowonjezera mphamvu mu mortars zopangidwa ndi simenti, zomatira za matailosi, ndi zipangizo zopangidwa ndi gypsum. Mu mankhwala ndi zinthu zosamalira munthu, imagwiritsidwa ntchito ngati chomangirira, chopangira filimu, komanso chosinthira kukhuthala mu zokutira mapiritsi, mayankho a maso, mafuta odzola, mafuta odzola, ndi shampu.
5. Mkhalidwe Wolamulira: Methyl Hydroxyethylcellulose nthawi zambiri imaonedwa kuti ndi yotetezeka (GRAS) pa ntchito zake m'mafakitale osiyanasiyana. Komabe, zofunikira zina zolamulira zimatha kusiyana kutengera dziko kapena dera lomwe mukugwiritsa ntchito. Ndikofunikira kutsatira malamulo ndi malangizo oyenera popanga zinthu zomwe zili ndi MHEC.

Ponseponse, Methyl Hydroxyethylcellulose ndi chinthu chochokera ku cellulose chomwe chimagwiritsidwa ntchito m'njira zosiyanasiyana ndipo chili ndi zinthu zambiri zofunika pa ntchito zosiyanasiyana zamafakitale ndi zamalonda. Kutha kwake kukonza mphamvu za rheological za mapangidwe kumapangitsa kuti ikhale chisankho chabwino kwambiri chokwaniritsa magwiridwe antchito omwe amafunidwa pazinthu zosiyanasiyana.
