Hydroxypropyl methyl cellulose ether ga busassun gauraye shirye cakuda turmi

A busassun gauraye gauraye turmi, abun ciki na HPMCE ya ragu sosai, amma yana iya inganta aikin rigar turmi. Madaidaicin zaɓi na ether cellulose tare da nau'ikan iri daban-daban, danko daban-daban, girman nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan nau'ikan danko daban-daban da adadin ƙari yana da tasiri akan aikin busassun turmi. A halin yanzu, yawancin masonry da plastering turmi aikin riƙe ruwa ba su da kyau, 'yan mintoci kaɗan za su bayyana ɗan tsayayyen rabuwar ruwa. Riƙewar ruwa wani muhimmin abu ne na Methyl cellulose ether, wanda kuma ya damu da yawancin busassun turmi a China, musamman a kudancin inda zafin jiki ya fi girma. Abubuwan da suka shafi riƙewar ruwa na busassun turmi sun hada da adadin cellulose ether HPMC, danko na cellulose ether HPMC, fineness na barbashi da zafin jiki na yanayi. Cellulose ether wani nau'in polymer ne na roba wanda aka yi daga cellulose na halitta ta hanyar gyaran sinadaran. Eter cellulose mai narkewa mai ruwa yana taka muhimmiyar rawa a cikin turmi a cikin bangarori uku, ɗayan shine kyakkyawan ƙarfin riƙe ruwa, ɗayan shine tasiri akan daidaiton turmi da thixotropy, na uku shine hulɗar da siminti. Aikin kiyaye ruwa na ether cellulose ya dogara ne akan shayar da ruwa na tushe, abun da ke tattare da turmi, kauri na turmi, buƙatar ruwa na turmi da kuma saita lokacin saitin kayan aiki. Riƙewar ruwa na ether cellulose kanta ya fito ne daga solubility da dehydration na cellulose ether kanta.
