Sakamakon sakamako na cellulose ether

Cellulose etherendows rigar turmi da kyau kwarai danko, iya muhimmanci ƙara bonding ikon rigar turmi da grassroots, inganta anti-sag yi na turmi, yadu amfani a plaster turmi, waje rufi tsarin da bulo bonding turmi. A thickening sakamako na cellulose ether kuma iya ƙara uniformity da anti-watsawa ikon sabon ciminti tushen kayan, don hana stratification, segregation da zub da jini na turmi da kankare, za a iya amfani da fiber kankare, karkashin ruwa kankare da kai compacting kankare.

Cellulose etheryana ƙara danko na kayan da ke da siminti daga danko na ether cellulose. Yawancin lokaci amfani da "danko" wannan ma'auni don kimanta cellulose ether bayani danko, da danko na cellulose ether kullum yana nufin wani taro (2%) na cellulose ether bayani, zafin jiki (20 ℃) ​​da karfi kudi (ko juya gudun, kamar 20). RPM) yanayi, tare da tanadi na kayan aunawa, kamar jujjuyawar ma'aunin ma'aunin viscosity. Danko ne wani muhimmin siga na kimanta aikin cellulose ether da cellulose ether, da mafi girma da danko da mafita, da mafi kyau danko na siminti tushe abu, da danko na tushe abu iya, sag juriya da juriya ga karfi da watsawa ikon. amma idan danko ya yi girma sosai, zai iya shafar motsin siminti tushe da motsin motsi (kamar ginin plaster turmi m. plaster). Saboda haka, dankowar ether cellulose da ake amfani da shi a cikin busassun turmi mai gauraya yawanci 15,000 ~ 60,000 Mpa. s-1, kuma ana buƙatar danko na ether cellulose don zama ƙasa don turmi mai daidaita kai da kuma taurin kai tare da buƙatun ruwa mafi girma. Bugu da ƙari, tasirin tasirin ether cellulose zai ƙara yawan abin da ake bukata na ruwa na kayan da aka yi da siminti, don haka ƙara yawan fitowar turmi. Dankowar maganin ether cellulose ya dogara da nauyin kwayoyin halitta (ko digiri na polymerization) da kuma maida hankali na ether cellulose, zafin bayani, ƙimar ƙarfi, da hanyar gwaji. Mafi girman digiri na polymerization na ether cellulose, mafi girman nauyin kwayoyin halitta, mafi girma da danko na maganin ruwa; Mafi girman sashi (ko maida hankali) na ether cellulose, mafi girman danko na maganin ruwa mai ruwa, amma a amfani da shi ya kamata a kula da zaɓin adadin da ya dace, don kada ya haɗu da tsayi, yana shafar aikin turmi da kankare; Kamar yawancin ruwaye, danko na cellulose ether bayani zai ragu tare da karuwar yawan zafin jiki, kuma mafi girman ƙaddamar da ether cellulose, mafi girman tasirin zafin jiki; Maganin ether na Cellulose yawanci jikin pseudoplastic ne tare da mallakar tsiro mai ƙarfi. Mafi girman ƙimar shear, ƙananan danko.

Sabili da haka, haɗin gwiwar turmi zai ragu ta hanyar karfi na waje, wanda ke taimakawa wajen gyaran ginin turmi, yin turmi zai iya samun kyakkyawan aiki da haɗin kai. Duk da haka, maganin ether cellulose zai nuna halaye na ruwa na Newtonian lokacin da maida hankali ya ragu sosai kuma danko yana da ƙananan. Lokacin da maida hankali ya karu, maganin a hankali yana gabatar da halayen ruwa na pseudoplastic, kuma mafi girma da maida hankali, mafi bayyane pseudoplastic.
