1 Isingeniso I-Cellulose ether (MC) isetshenziswa kakhulu embonini yezinto zokwakha futhi isetshenziswa ngenani elikhulu. Ingasetshenziswa njenge-retarder, i-ejenti yokugcina amanzi, i-thickener kanye ne-adhesive. Odakeni olujwayelekile oluxutshwe okomile, udaka lwangaphandle olufakwa odongeni, udaka oluzilinganisa ngokwalo, okunamathelisa amathayela, okuphezulu...Funda kabanzi»
