Methylhydroxyethylcellulose (MHEC) ndi chowonjezera chomwe chimagwiritsidwa ntchito kwambiri muzinthu zopangira simenti monga matope ndi konkriti.Ndi ya banja la cellulose ethers ndipo imachotsedwa ku cellulose yachilengedwe kudzera munjira yosintha mankhwala.
MHEC imagwiritsidwa ntchito makamaka ngati chowonjezera, chosungira madzi ndi rheology modifier muzinthu zopangidwa ndi simenti.Zimathandizira kukonza magwiridwe antchito komanso kusasinthika kwa zosakaniza za simenti, zomwe zimapangitsa kuti zikhale zosavuta kuzigwira pomanga.MHEC imaperekanso maubwino ena angapo, kuphatikiza:
Kusungirako madzi: MHEC imatha kusunga madzi, zomwe zimalepheretsa kuyanika zinthu zopangidwa ndi simenti msanga.Izi ndizothandiza makamaka kumadera otentha, kowuma kapena pakafunika nthawi yayitali yogwira ntchito.
Kumamatira Kwabwino: MHEC imathandizira kumamatira pakati pa zida za simenti ndi magawo ena monga njerwa, miyala kapena matailosi.Zimathandizira kulimbitsa mphamvu zamagwirizano ndikuchepetsa mwayi wa delamination kapena kupatukana.
Nthawi Yowonjezera Yotsegulira: Nthawi yotsegula ndi kuchuluka kwa nthawi yomwe matope kapena zomatira zimakhalabe zogwiritsidwa ntchito pomanga.MHEC imalola nthawi yotseguka yotalikirapo, kulola nthawi yayitali yogwira ntchito komanso kukonza bwino zinthuzo zisanakhazikike.
Kukaniza kwa Sag Resistance: Kukaniza kwa Sag kumatanthauza kuthekera kwa chinthu kukana kutsika kolunjika kapena kugwedezeka kukagwiritsidwa ntchito pamtunda.MHEC imatha kupititsa patsogolo kukana kwa zinthu zopangidwa ndi simenti, kuwonetsetsa kuti kumamatira bwino komanso kuchepetsa kusinthika.
Kupititsa patsogolo ntchito: MHEC imasintha machitidwe a zipangizo za simenti, kupititsa patsogolo kuyenda kwawo ndi kufalikira.Zimathandizira kuti pakhale kusakanikirana kosalala komanso kosasinthasintha, kumapangitsa kuti zikhale zosavuta kuzigwira ndikugwiritsa ntchito.
Nthawi Yoyikira Nthawi: MHEC ikhoza kukhudza nthawi yoyika zinthu za simenti, zomwe zimapangitsa kuti pakhale kulamulira kwakukulu pa njira yochiritsira.Izi ndizofunikira makamaka pakafunika nthawi yayitali kapena yayifupi yokhazikitsa.
Tiyenera kuzindikira kuti zinthu zenizeni ndi ntchito za MHEC zingasiyane malinga ndi kulemera kwake kwa maselo, mlingo wolowa m'malo, ndi zina.Opanga osiyanasiyana atha kupereka zinthu za MHEC zokhala ndi mawonekedwe osiyanasiyana kuti zigwirizane ndi ntchito zina.
Ponseponse, MHEC ndizowonjezera zowonjezera zomwe zimatha kupititsa patsogolo magwiridwe antchito ndi kusinthika kwazinthu zopangira simenti, zomwe zimapereka zopindulitsa monga kumamatira bwino, kusunga madzi, kukana kwa sag komanso nthawi yokhazikika.
