Zotsatira za hydroxypropyl methylcellulose pa ntchito yosunga madzi ya pulasitala youma

Kuchuluka kwa hydroxypropyl methylcellulose ether kumasunga madzi mu matope kwa nthawi yokwanira kuti simenti ipitirize kunyowa komanso kumamatira bwino pakati pa matope ndi substrate.

Zotsatira za Kukula kwa Tinthu ndi Nthawi Yosakaniza ya Hydroxypropyl Methyl Cellulose Ether pa Kusunga Madzi

Mphamvu yosungira madzi mu matope imayang'aniridwa kwambiri ndi nthawi yosungunuka, ndipo cellulose yosalala imasungunuka mwachangu, ndipo mphamvu yosungira madzi imathamanga kwambiri. Pakupanga makina, chifukwa cha nthawi yochepa, kusankha cellulose kuyenera kukhala ufa wosalala. Pakuyika pulasitala pamanja, ufa wosalala uyenera.

Zotsatira za Etherification Degree ndi Kutentha kwa Hydroxypropyl Methyl Cellulose Ether pa Kusunga Madzi

Kusungunuka ndi kutentha kwa hydroxypropyl methylcellulose m'madzi kumadalira kuchuluka kwa etherification. Pamene kutentha kwakunja kukukwera, kusunga madzi kumachepa; kuchuluka kwa etherification kukakhala kwakukulu, kusunga madzi kwa cellulose ether kumakhala bwino.

Zotsatira za efa ya hydroxypropyl methylcellulose pa kusasinthasintha ndi kukana kwa matope

Kugwirizana ndi mphamvu ya matope oletsa kutsetsereka ndi zizindikiro zofunika kwambiri, zonse ziwiri pakupanga kokhuthala komanso zomatira za matailosi zimafunika mphamvu yoyenera komanso mphamvu yoletsa kutsetsereka.

Njira yoyesera kusinthasintha, yotsimikizika malinga ndi muyezo wa JG/J70-2009

Kusasinthasintha ndi kukana kutsetsereka kumachitika makamaka chifukwa cha kukhuthala ndi kukula kwa tinthu ta hydroxypropyl methylcellulose. Kukhuthala ndi kuchuluka kwa tinthu ta matope kumawonjezeka; kukula kwa tinthu ta matope tikakhala tating'onoting'ono, kusinthasintha koyambirira kwa tinthu ta matope osakanikirana kumene kumawonjezeka mwachangu.

Zotsatira za Hydroxypropyl Methyl Cellulose pa Kulowetsa Mpweya kwa Mchere

Chifukwa cha kuwonjezera hydroxypropyl methylcellulose mu matope, mpweya wochepa, wofanana komanso wokhazikika umalowetsedwa mu matope atsopano osakanizidwa. Chifukwa cha mphamvu ya mpira, matopewo amakhala ndi kapangidwe kabwino ndipo amachepetsa kuchepa ndi kugwedezeka kwa matopewo. Amasweka, ndikuwonjezera kuchuluka kwa kutulutsa kwa matopewo. Cellulose ili ndi ntchito yolowetsa mpweya. Mukawonjezera cellulose, ganizirani mlingo, kukhuthala (kukhuthala kwakukulu kudzakhudza kugwira ntchito), ndi makhalidwe olowetsa mpweya. Sankhani cellulose pa matope osiyanasiyana.
