Hydroxypyl methyl selululose hpmc na jinkirta cement hydration
Dingara Hydroxypypyl methyl seluluose zuwa ciminti yayi jinkiri da hydration ta. Don haka me ka sani game da yadda yake aiki? Bari mu kalli selpypyl methyl selululose pellulose don jinkirta sinadiyar hydration. Manufa.
1. Ion rikice rikice
Mun hyatar da cewa metroxypyl methyl selulose zai kara danko na poore solutions, hana rage yawan motsi na ionic, da kuma jinkirta hydration na ciminti. Koyaya, ƙananan kayan danko mai kare cewa a cikin wannan gwajin yana da iko mai ƙarfi don jinkirta sinadiyar ciminti. Saboda haka, wannan zato bai dace ba. Pickchez et al. Hakanan duk shakkar wannan hasashe. A zahiri, lokacin hion hijirar ko hijirarsa ba shi da kyau, a fili ba dissimilar ba don jinkirin hydration ciminti.
2. Alakarine Degradation
Polysaccharises cikin sauri yana lalata a ƙarƙashin yanayin alkaline don samar da carboxyl carboxyl carboxyl na hydroxyl wanda zai jinkirta siminti. Sabili da haka, jinkirta hydration na hydroxypropyl methyl pellulose na iya zama saboda lalata ta a cikin alkaline cemtimenboxylic acid. Koyaya, zuba al. An gano cewa selulose na da za a iya tsayawa a ƙarƙashin yanayin alkaline, wanda aka lalata kawai, da samfuran lalata ba su da tasiri akan jinkiri na ciminti.
3, adsorption
AdsorPypypyl na iya zama hydroxypropyl methyl selululose toshe ciminti hydation da ainihin kayan kwastomomi, don jinkirta hydration da cryinensation na sumunti. Pickchez et al. An gano cewa seluloos Ehers a cikin saman kayan hydring, csh gel da alli a cikin asirin da Ettrendite da ba a kwance su ba. Haka kuma, a batun magana ether, etan adsorption na hec ya fi karfi fiye da na kumburi MC. Thearamar da abun ciki na Hydroxyethyl a cikin HEC ko Hydroxypropyl a HPMC, mafi karfi na kayan hydroxide ya fi ta ch. An kara da bincike kan yadda ake iya karfin kayan masarufi da eth eth etal, amma a bayyane yake, amma hakan ya jinkirta sosai. cellulose ether of tricalcium silicate and its hydration products has a strong adsorption, it obviously delay the hydration process of silicate phase, the adsorption amount of ettringite is very low, but delayed ettringite formation is obvious, because of delayed ettringite formation is affected by Ca 2 + balance in the solution, it is an extension of the cellulose ether. Latti silicing hydration ya ci gaba.
Waɗannan sune ƙwayar ƙwayar ƙwayar ƙwallon ƙwallon ƙwallon ƙwallon ƙwallon ƙwallon ƙwallon ƙwallon ƙwallon ƙwallon ƙafa ta bata dacewar hanya. Muna fatan wannan ilimin zai taimaka wa kowa ya fahimci yadda samfurin yake aiki kuma ya fi amfani dashi.
