MHEC (Methyl Hydroxyethyl Cellulose) imwe cellulose-based polymer iyo inowanzoshandiswa sekuwedzera mune simende-based rendering application. Iyo ine mabhenefiti akafanana kune HPMC, asi ine mimwe misiyano yezvivakwa. Izvi zvinotevera mashandisirwo eMHEC mumapurasita esimende:
Kuchengetwa kwemvura: MHEC inowedzera kuchengetwa kwemvura mumusanganiswa wepurasita, nokudaro kuwedzera kushanda. Inobatsira kudzivirira musanganiswa kubva pakuoma nguva isati yakwana, zvichibvumira nguva yakakwana yekushandisa uye kupedza.
Kushanda: MHEC inovandudza kushanda uye kupararira kwezvinhu zvekupura. Inonatsiridza kubatana uye kuyerera zvivakwa, zvichiita kuti zvive nyore kuisa uye kuzadzisa yakapfava kupedzisa pamusoro penzvimbo.
Adhesion: MHEC inokurudzira kunamatira zviri nani kwepurasita kune substrate. Inobatsira kuvimbisa chisungo chakasimba pakati pepurasita uye pasi pepamusoro, kuderedza njodzi ye delamination kana kupatsanurwa.
Sag Resistance: MHEC inopa thixotropy kumusanganiswa wepurasita, ichivandudza kuramba kwayo kusag kana kudonha kana yaiswa vertically kana pamusoro. Inobatsira kuchengetedza hupamhi hunodiwa uye chimiro chepurasita panguva yekushandiswa.
Mutswe kuramba: Nekuwedzera MHEC, iyo plastering zvinhu inowana yakakwirira kuchinjika uye nekudaro inosimudzira kutsemuka kuramba. Inobatsira kuderedza kuitika kwekutsemuka kunokonzerwa nekuomesa shrinkage kana kupisa kwekuwedzera / kuderera.
Durability: MHEC inobatsira kusimba kweiyo plastering system. Inoumba firimu rinodzivirira kana rakaoma, richiwedzera kupikisa kupinda kwemvura, mamiriro ekunze uye zvimwe zvakatipoteredza.
Rheology Control: MHEC inoshanda se rheology modifier, inokanganisa kuyerera uye kushanda kwemusanganiswa wekupa. Inobatsira kudzora viscosity, inovandudza kupomba kana kupfapfaidza hunhu, uye inodzivirira kugadzirisa kana kupatsanurwa kwezvimedu zvakasimba.
Izvo zvinofanirwa kucherechedzwa kuti iyo chaiyo chiyero uye kusarudzwa kweMHEC kunogona kusiyana zvichienderana nezvinodiwa chaizvo zveplastering system, senge ukobvu hunodiwa, kurapa mamiriro uye zvimwe zvinhu. Vagadziri vanowanzopa nhungamiro uye tekinoroji data mapepa ane akakurudzirwa mazinga ekushandisa uye mirairo yekubatanidza MHEC mune cementitious gypsum formulations.
