1 Isingeniso I-cellulose ether (MC) isetshenziswa kabanzi embonini yezinto zokwakha futhi isetshenziswa ngobuningi. Ingasetshenziswa njenge-retarder, i-ejenti yokugcina amanzi, i-thickener kanye ne-glue. Ku-mortar evamile exutshwe okomile, i-mortar yangaphandle yokuvikela udonga, i-mortar ezilinganisayo, i-glue yethayela, i-high-p...Funda kabanzi»

Impuphu ye-polymer ephinde ihlakazeke ivame ukubonakala ekwakheni njengento yokuvikela udonga yangaphandle. Yakhiwe kakhulu ngezinhlayiya ze-polystyrene kanye nempuphu ye-polymer, ngakho-ke iqanjwe ngenxa yokwahluka kwayo. Lolu hlobo lwempuphu ye-polymer yokwakha lwenzelwe ikakhulukazi ukuhluka kwe-poly...Funda kabanzi»
