Tsopano kuti pali misika yochulukirapo ya hydroxpyl carboxymethyl cellose ndipo mitengo mosavuta ndikudziwa mtundu wa carboxymethyl cartaluulyl yakhala nkhani yovuta! Ndiye momwe mungaweruzire mtundu wa hydroxypypyl methylcelulose? Chinthu choyamba kuyang'ana ndi kuyera kwa hydroxypropyl cellulose; Ngakhale kuyeta sikungadziwe ngati HPMC ndi yoyenera kugwiritsidwa ntchito, opanga ena osavomerezeka adzawonjezera choyera choyera pokonzanso, zomwe zingakhudze mtundu wake. Koma nthawi zambiri, ambiri mwa ma celluse amakhala ndi kuyera kwabwino.
Kachiwiri, zimatengera kukongola kwa hydroxpyl methylcellulose, kukula kwa ma hydroxypthyl carloulyl cellulose HechPuluse ndi ma mesh okwana 100. Ambiri mwa HPMC ndi ma mesh. Nthawi zambiri, amafewetsa celylose cellulose, kukhala ndi mwayi wobalalitsidwa.
Chizindikiro cha cellulose ether mu yankho: Ikani hpmc m'madzi kuti mupange yankho la colloidal, chomwe chimveka, chomveka bwinocho, pansi pazinthu zokhumudwitsa.
Pakakhala kuti katunduyo amatenthetsedwa, imagwedezeka kapena dziwe kenako nkusungunuka. Ndi hydrophobic ndi sungunuka. Konkriti ndiye kulumikizana kwakukulu ndikuwononga zinthu zopangira ufa wogwiritsa ntchito madzi. Mfundo yogwirizana ndi madzi ndi motere: pomwe simenti yotsitsidwa ndi simenti yofiyira, ufa wa latedx ipitiliza kubwerera ku Emulsion Fomu, ndipo tinthu timenex timabalalika kwambiri mu simenti. Pambuyo pa simenti imakumana ndi madzi, ma hydration zomwe amachita zimayamba, ndi a ca (o) 2 njira imafikira masiketi ndi makristali. Nthawi yomweyo, makhiristo a udzu ndi calcium silture ma Colloids a Colloid amapangidwa, ndipo tinthu tating'ono tating'onoting'ono timasungidwa, monga momwe zinthu zamagetsi zimapitilira, ndipo masamba a latex pang'onopang'ono Sonkhanitsani mu voids ya zinthu zachilengedwe monga simenti, ndikupanga mawonekedwe owoneka bwino pamwamba pa simenti gel. , chifukwa cha kuchepetsa pang'onopang'ono kwa chinyezi chouma, chomwe chimapangidwa kwambiri cha Cels mu gel osakaniza kupanga filimu yopitilira muyeso, ndikupanga simenti ndi ufa wa simenti amapangika wina ndi mnzake.
