Cellulose ether HPMC a siminti turmi da gypsum tushen slurry, yafi taka rawa da ruwa riƙewa da thickening, iya yadda ya kamata inganta mannewa da sag juriya na slurry.
Zazzabi na iska, zafin jiki da matsa lamba na iska na iya shafar yawan ƙawancen ruwa a cikin turmi siminti da samfuran tushen gypsum. A cikin yanayi daban-daban, ana iya daidaita tasirin riƙe ruwa na slurry ta ƙara ko rage adadin HPMC. A cikin gina yanayin zafi mai zafi, don cimma tasirin kiyaye ruwa, ya zama dole don ƙara samfuran HPMC da yawa bisa ga dabara. In ba haka ba, za a sami rashin isasshen ruwa, raguwar ƙarfi, tsagewa, busasshiyar bushewa da sauri da sauran matsaloli masu inganci. Yayin da zafin jiki ya ragu, za a iya rage yawan adadin HPMC a hankali, kuma ana iya samun irin wannan tasirin ruwa.
Akwai wasu bambance-bambance da dalilai na tasirin riƙe ruwa na adadin samfuran da aka ƙara HPMC. Mafi kyawun samfuran samfuran HPMC na iya magance matsalar riƙewar ruwa a ƙarƙashin babban zafin jiki. A cikin yanayin zafi mai zafi, musamman a wurare masu zafi da bushewa da kuma gine-gine na bakin ciki a gefen rana, ana buƙatar HPMC mai inganci don inganta yawan ruwa na slurry. High quality HPMC, ta methoxy da hydroxypropyl kungiyoyin tare da cellulose kwayoyin sarkar uniform rarraba, iya inganta hydroxyl da ether bond a kan oxygen atom da ruwa kungiyar hydrogen bond ikon, sa free ruwa a cikin hade ruwa. Kuma yadda ya kamata tarwatsa a cikin slurry da kuma nannade duk m barbashi, hydration dauki tare da inorganic cementing kayan, da kuma samuwar wani Layer na wetting fim, ruwa a cikin tushe sannu a hankali saki na dogon lokaci, don yadda ya kamata sarrafa evaporation na ruwa sa. ta yanayin zafi mai zafi, don cimma babban riƙewar ruwa.
Riƙewar ruwa na samfuran HPMC galibi yana shafar abubuwa masu zuwa:
1. The HPMC uniformity: Uniform dauki na HPMC, methoxy, hydroxypropoxy uniform rarraba, high ruwa riƙewa.
2 HPMC thermal gel zafin jiki: Hot gel yana da girma
zafin jiki da yawan riƙe ruwa; in ba haka ba, yana da ƙarancin riƙe ruwa.
3. A danko na HPMC: Lokacin da danko na HPMC ya karu, da ruwa riƙe kudi kuma ƙara. Lokacin da
danko ya kai wani mataki, karuwar yawan ajiyar ruwa yakan zama mai laushi.
4. Abubuwan da ke cikin HPMC: Ƙarin ƙarin HPMC da aka ƙara, mafi girma yawan adadin ruwa kuma mafi kyawun tasirin ruwa. A cikin kewayon 0.25-0.6%, ƙimar kiyaye ruwa ya karu da sauri tare da ƙara yawan adadin. Lokacin da ƙarin adadin ya ƙara ƙaruwa, yanayin haɓakar ƙimar kiyaye ruwa ya zama a hankali.
