Methyl Hydroxyethyl Cellulose (MHEC/HEMC)
CAS:9032-42-2
Hydroxyethyl Methyl Cellulose (HEMC) imatchedwanso kutiMethyl Hydroxyethyl Cellulose(MHEC), ether ya cellulose yogwira ntchito bwino komanso yogwira ntchito bwino yomwe imagwiritsidwa ntchito ngati chosungira madzi, chokhazikika, zomatira ndi chopangira filimu m'mitundu yosiyanasiyana ya zipangizo zomangira. MHEC/HEMC imagwiritsidwa ntchito kwambiri m'mafakitale, monga zomangamanga, sopo, utoto ndi zokutira, tithanso kupereka HEMC malinga ndi zosowa za makasitomala. Tikasintha ndi kukonza pamwamba, titha kupeza katundu yemwe amamwazika m'madzi mwachangu, kutalikitsa nthawi yotseguka, kuletsa kugwa, ndi zina zotero.

Kapangidwe ka Mankhwala a MHEC
MHEC imapangidwa ndicellulose yachilengedwe yopatsa mphamvundimagulu a methyl ndi hydroxyethylZosinthazi zimathandizira kuti zinthu zake ziyende bwinokusungunuka kwa madzi, kukhuthala, ndi kugwirizanandi zipangizo zosiyanasiyana.
Makhalidwe Ofunika a MHEC:
- Kusungunuka kwa Madzi: Kusungunuka m'madzi otentha ndi ozizira, kupanga njira zowonekera bwino.
- Kutha Kukhuthala: Kumapereka kukhuthala kwakukulu komanso kuwongolera bwino kwa rheology.
- Kusunga Madzi: Kumaletsa kutayika kwa madzi mu zinthu zopangidwa ndi simenti ndi gypsum, zomwe zimapangitsa kuti madzi azigwira bwino ntchito komanso kuti azigwira bwino ntchito.
- Chilengedwe Chosakhala cha Ionic: Chimagwirizana ndi mankhwala osiyanasiyana, kuphatikizapo mchere ndi zinthu zina zosungunulira.
- Luso Lopanga Mafilimu: Amapanga mafilimu osinthasintha komanso olimba, othandiza pakuphimba ndi kugwiritsa ntchito mankhwala.
- Kukhazikika kwa Kutentha: Kulimba ku kutentha, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kutentha kwambiri.

Ubwino Wogwiritsa Ntchito MHEC
✔ Kusunga Madzi Bwino Kwambiri - Kumaletsa kuumitsa msanga pa ntchito zomangira ndi zokongoletsa.
✔ Kumamatira Kowonjezereka - Kumalimbitsa mphamvu yomamatira mu zomatira za matailosi ndi ma mortar.
✔ Yokhazikika pa pH yochuluka - Imagwira ntchito bwino m'malo okhala ndi acidity, neutral, komanso alkaline.
✔ Kugwirizana Kopanda Ionic - Kumagwira ntchito bwino ndi mchere, ma surfactants, ndi ma polima ena.
✔ Imawongolera Makhalidwe a Rheology ndi Kuyenda kwa Madzi - Imalola kukhuthala koyenera, kupewa kutsika ndi kugwa.
Kupaka:
Chogulitsa cha MHEC/HEMC chili m'thumba la mapepala la magawo atatu lokhala ndi thumba lamkati la polyethylene lolimbikitsidwa, kulemera konse ndi 25kg pa thumba lililonse.
Malo Osungira:
Sungani m'nyumba yosungiramo zinthu zozizira komanso zouma, kutali ndi chinyezi, dzuwa, moto, kapena mvula.
