MHEC ya pulasitala opangidwa ndi simenti

MHEC (Methyl Hydroxyethyl Cellulose) ndi polima ina yopangidwa ndi cellulose yomwe imagwiritsidwa ntchito ngati chowonjezera pakugwiritsa ntchito simenti.Ili ndi ubwino wofanana ndi HPMC, koma ili ndi kusiyana kwa katundu.Zotsatirazi ndi zomwe MHEC amagwiritsa ntchito pamapulasitala a simenti:

Kusungirako madzi: MHEC imawonjezera kusungidwa kwa madzi muzosakaniza zopaka pulasitala, motero zimatalikitsa kugwira ntchito.Zimathandiza kuti chisakanizocho chisawume msanga, kupereka nthawi yokwanira yogwiritsira ntchito ndikumaliza.

Kugwira ntchito: MHEC imapangitsa kuti ntchito yopaka pulasitala ikhale yabwino komanso kufalikira.Imawongolera kugwirizanitsa ndi kuyendayenda, kumapangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikukwaniritsa mapeto osalala pamtunda.

Kumamatira: MHEC imalimbikitsa kumamatira bwino kwa pulasitala ku gawo lapansi.Zimathandiza kuonetsetsa mgwirizano wamphamvu pakati pa pulasitala ndi pansi, kuchepetsa chiopsezo cha delamination kapena kupatukana.

Sag Resistance: MHEC imapatsa thixotropy kusakaniza kwa pulasitala, kuwongolera kukana kwake kuti isagwe kapena kutsika ikagwiritsidwa ntchito molunjika kapena pamwamba.Zimathandiza kusunga makulidwe ofunikira ndi mawonekedwe a pulasitala panthawi yogwiritsira ntchito.

Kukana kwa Crack: Powonjezera MHEC, zinthu zopaka pulasitala zimakhala zosinthika kwambiri motero zimakulitsa kukana kwa ming'alu.Zimathandizira kuchepetsa kuchitika kwa ming'alu yomwe imabwera chifukwa cha kuyanika kwakuya kapena kukulitsa / kutsika kwamafuta.

Kukhalitsa: MHEC imathandizira kulimba kwa pulasitala.Zimapanga filimu yoteteza ikauma, kuonjezera kukana kulowa kwa madzi, nyengo ndi zinthu zina zachilengedwe.

Rheology Control: MHEC imagwira ntchito ngati rheology modifier, yomwe imakhudza kuyenda ndi kugwira ntchito kwa kusakaniza kopereka.Imathandiza kulamulira mamasukidwe akayendedwe, bwino kupopera kapena kupopera mbewu mankhwalawa makhalidwe, ndi kupewa kukhazikika kapena kulekana kwa olimba particles.

Tiyenera kuzindikira kuti kuchuluka kwapadera ndi kusankha kwa MHEC kungakhale kosiyana malinga ndi zofunikira zenizeni za pulasitala, monga makulidwe ofunikira, machiritso ndi zinthu zina.Opanga nthawi zambiri amapereka malangizo ndi mapepala aukadaulo omwe ali ndi milingo yovomerezeka yogwiritsira ntchito ndi malangizo ophatikizira MHEC muzopanga zama gypsum cementitious.
