JINJI ® HPMC da aka yi amfani da shi wajen daidaita kai
Haɗaɗɗen matakin kai su ne gaurayawan sinadarai da ake amfani da su don santsin siminti ko benaye na katako. Sun ƙunshi siminti, yashi, masu filaye, kuma an gyara su ta nau'ikan ƙari kamar ethers cellulose, robobi, defoamers, stabilizers, da foda masu iya tarwatsawa. A matsayin mai gudana, matakin kai-da-kai da kayan daɗaɗɗen kai, mahaɗan matakan kai tsaye na iya haifar da ɗaki mai laushi, santsi, da wuya wanda ke da kyakkyawan ƙarfin matsawa.
Ƙarin HPMC na iya haɓaka kaddarorin masu zuwa a cikin aikace-aikacen mahalli masu daidaita kai:
Yawowa
A matsayin turmi mai daidaita kai, ruwa yana ɗaya daga cikin manyan alamomi don kimanta aikin matakin kai. A karkashin yanayin tabbatar da ka'idodin tsarin turmi, ana iya daidaita yawan ruwan turmi ta hanyar canza abun ciki na fiber HPMC. Duk da haka, babban abun ciki zai rage yawan ruwa na turmi, don haka adadin ether cellulose ya kamata a sarrafa shi a cikin kewayon da ya dace.
Riƙewar Ruwa
Riƙewar ruwan turmi alama ce mai mahimmanci na kwanciyar hankali na abubuwan ciki na sabon turmi siminti. Don yin aikin hydration na kayan gel ɗin da aka cika da shi, daidaitaccen adadin ether cellulose zai iya ajiye ruwa a cikin turmi na dogon lokaci. Gabaɗaya, riƙewar ruwa na slurry yana ƙaruwa tare da haɓaka abun ciki na ether cellulose. Riƙewar ruwa na ether cellulose zai iya hana abin da ake amfani da shi daga ɗaukar ruwa mai yawa da sauri da kuma hana ruwa gudu, don haka tabbatar da cewa yanayin slurry yana samar da isasshen ruwa don samar da ruwa na siminti. Bugu da ƙari, danko na cellulose ether kuma yana da tasiri mai mahimmanci akan riƙe ruwa na turmi. Mafi girman danko, mafi kyawun riƙewar ruwa.
Saitin lokaci
HPMC yana da saurin saitin tasiri akan turmi. Tare da haɓaka abun ciki na ether cellulose, lokacin saita turmi yana tsawaita. Sakamakon retarding na cellulose ether akan slurry siminti ya dogara ne akan matakin maye gurbin ƙungiyar alkyl, wanda ba shi da alaƙa da nauyin kwayoyinsa. Ƙarƙashin matakin maye gurbin alkyl, mafi girman abun ciki na hydroxyl, mafi bayyane tasirin jinkirtawa. Kuma mafi girman abun ciki na ether cellulose, mafi mahimmancin tasirin tasirin fim ɗin akan farkon hydration na siminti. Sabili da haka, mafi mahimmancin tasirin retarding shine.
Turmi mai daidaita kai na iya dogara da nauyin kai don samar da tushe mai santsi, santsi da ƙwaƙƙwal akan mashin don kwanciya ko haɗa wasu kayan, yayin ba da damar ingantaccen gini akan babban yanki.
