MHEC ya ma plaster opangidwa ndi simenti

MHEC (Methyl Hydroxyethyl Cellulose) ndi polima ina yopangidwa ndi cellulose yomwe imagwiritsidwa ntchito kwambiri ngati chowonjezera pakupanga zinthu pogwiritsa ntchito simenti. Ili ndi ubwino wofanana ndi wa HPMC, koma ili ndi kusiyana kwa makhalidwe. Izi ndi zomwe MHEC imagwiritsa ntchito pa ma plaster opangidwa ndi simenti:

Kusunga madzi: MHEC imawonjezera kusunga madzi mu chisakanizo cha pulasitala, motero imawonjezera kugwira ntchito. Imathandiza kuti chisakanizocho chisamaume msanga, zomwe zimapangitsa kuti pakhale nthawi yokwanira yogwiritsira ntchito ndi kumaliza.

Kugwira Ntchito: MHEC imapangitsa kuti zinthu zopaka pulasitala zigwire ntchito bwino komanso kuti zifalikire bwino. Imapangitsa kuti zikhale zosavuta kugwiritsa ntchito komanso kuti zigwire bwino ntchito, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito komanso kuti zinthuzo zikhale zosalala pamalopo.

Kumatirira: MHEC imalimbikitsa kuti pulasitala imamatire bwino ku substrate. Imathandiza kuti pulasitalayo ikhale yolimba komanso pamwamba pake pakhale mgwirizano wolimba, zomwe zimathandiza kuchepetsa chiopsezo cha kugawanika kapena kupatukana.

Kukana Kusagwa: MHEC imapatsa thixotropy ku chisakanizo cha pulasitala, zomwe zimapangitsa kuti chisagwe kapena kutsika chikagwiritsidwa ntchito moyimirira kapena pamwamba. Zimathandiza kusunga makulidwe ndi mawonekedwe a pulasitalayo panthawi yogwiritsidwa ntchito.

Kukana ming'alu: Mwa kuwonjezera MHEC, pulasitalayo imakhala yosinthasintha kwambiri motero imawonjezera kukana ming'alu. Zimathandiza kuchepetsa ming'alu yomwe imabwera chifukwa cha kuuma kapena kutentha kwambiri.

Kulimba: MHEC imathandizira kuti dongosolo lopaka pulasitala likhale lolimba. Limapanga filimu yoteteza ikauma, zomwe zimapangitsa kuti madzi asalowe, nyengo ndi zinthu zina zachilengedwe zisamayende bwino.

Kulamulira Kuzungulira kwa Magazi: MHEC imagwira ntchito ngati chosinthira kuzungulira kwa magazi, zomwe zimakhudza kuyenda ndi kugwira ntchito kwa chisakanizocho. Imathandiza kuwongolera kukhuthala, kukonza mawonekedwe a kupopera kapena kupopera, komanso imaletsa kukhazikika kapena kulekanitsa tinthu tolimba.

Tiyenera kudziwa kuti kuchuluka ndi kusankha kwa MHEC kumatha kusiyanasiyana kutengera zofunikira za dongosolo lopaka pulasitala, monga makulidwe ofunikira, momwe amachiritsira ndi zina. Opanga nthawi zambiri amapereka malangizo ndi mapepala aukadaulo okhala ndi milingo yoyenera yogwiritsira ntchito komanso malangizo ogwiritsira ntchito MHEC mu mapangidwe a gypsum a simenti.
