Hydroxypropyl Methylcellulose (HPMC) ƙari ne da aka saba amfani da shi a cikin kayan tushen siminti, gami da turmi.Yana ba da dalilai daban-daban, gami da riƙe ruwa, haɓaka iya aiki, da haɓaka abubuwan mannewa.Tsarin riƙe ruwa na HPMC a cikin turmi siminti ya ƙunshi abubuwa da yawa:

1. Halin Hydrophilic: HPMC shine polymer hydrophilic, ma'ana yana da alaƙa mai ƙarfi ga ruwa.Lokacin da aka ƙara shi zuwa turmi, yana iya ɗaukar ruwa kuma ya riƙe ruwa a cikin tsarinsa na ƙwayoyin cuta.
2. Shingayen Jiki: HPMC yana samar da shinge na zahiri a kusa da barbashi na siminti da sauran tarukan da ke cikin cakuda turmi.Wannan shamaki yana taimakawa wajen hana ƙawancen ruwa daga cakuda, don haka kiyaye rabon ruwa-ciminti da ake so don hydration.
3. Gyaran Danko: HPMC na iya ƙara danko na cakuda turmi, wanda ke taimakawa wajen rage rabuwar ruwa (jini) da rarraba abubuwan da aka gyara.Wannan gyare-gyaren danko yana ba da gudummawa ga mafi kyawun riƙe ruwa a cikin turmi.
4. Samar da Fim: HPMC na iya samar da fim na bakin ciki a saman sassan siminti da tarawa.Wannan fim ɗin yana aiki azaman kariya mai kariya, yana rage asarar ruwa ta hanyar haɓakawa da haɓaka tsarin hydration na ƙwayoyin siminti.
5. Jinkirin Sakin Ruwa: HPMC na iya sakin ruwa a hankali cikin lokaci yayin da turmi ke warkewa.Wannan jinkirin sakin ruwa yana taimakawa wajen ci gaba da tsarin hydration na siminti, yana haɓaka haɓaka ƙarfi da dorewa a cikin turmi mai tauri.
6. Yin hulɗa da Siminti: HPMC yana hulɗa tare da barbashi na siminti ta hanyar haɗin gwiwar hydrogen da sauran hanyoyin.Wannan hulɗar tana taimakawa wajen daidaita ruwan siminti, yana hana rabuwa lokaci da kiyaye daidaituwa.
7. Dakatar da Barbashi: HPMC na iya aiki azaman wakili mai dakatarwa, adana barbashi na siminti da sauran ƙaƙƙarfan abubuwan da aka tarwatsa daidai gwargwado cikin cakuda turmi.Wannan dakatarwa yana hana daidaitawar barbashi kuma yana tabbatar da daidaiton rarraba ruwa.

Gabaɗaya, tsarin riƙe ruwa na HPMC a cikin turmi siminti ya ƙunshi haɗaɗɗun tasirin jiki, sinadarai, da rheological waɗanda ke aiki tare don kula da abun ciki da ake buƙata don ingantaccen ruwa da aikin turmi.
