Hydroxypropyl Methylcellulose (HPMC)wani muhimmin fili na ether cellulose ne wanda aka yi amfani da shi sosai a cikin kayan gini, musamman a cikin turmi na ciminti, kayan gypsum da kayan shafa. HPMC tana taka muhimmiyar rawa wajen inganta kaddarorin turmi, gami da inganta kaddarorin hana ruwa.
1. Inganta riƙon ruwa na turmi
Ɗaya daga cikin fitattun fasalulluka na HPMC shine kyakkyawan ƙarfin riƙewar ruwa. Ƙara HPMC zuwa turmi na iya rage yawan asarar ruwa a cikin turmi sosai. Takamammen aikin shine:
Tsawaita lokacin amsawar ruwan siminti: HPMC na iya kula da zafi mai dacewa a cikin turmi da kuma tabbatar da cewa barbashin simintin sun yi cikakkiyar amsa da ruwa don samar da samfurin ɗigon ruwa mai yawa.
Yana hana samuwar tsagewa: Rashin ruwa mai sauri zai iya haifar da turmi ya ragu kuma ya fara raguwa, don haka rage abubuwan hana ruwa.HPMCzai iya rage yawan asarar ruwa da kuma rage fasa da bushewar bushewa ke haifarwa.
Inganta aikin riƙe ruwa yana sanya tsarin ciki na turmi mai yawa, yana rage porosity, kuma yana inganta haɓakar turmi sosai, ta haka yana haɓaka aikin hana ruwa.
2. Inganta aikin turmi
Halayen danko na HPMC suna haɓaka kaddarorin rheological na turmi, ta haka inganta aikin sa:
Rage zub da jini: HPMC na iya tarwatsa ruwa daidai gwargwado, yana ba da damar rarraba ruwa da ƙarfi a cikin turmi da kuma rage kurajen da ke haifar da rabuwar ruwa.
Inganta mannewa na turmi: HPMC yana inganta ƙarfin haɗin gwiwa tsakanin turmi da kayan tushe, yana barin turmi ya rufe saman kayan tushe a hankali, ta haka ne rage yiwuwar danshi shiga ta hanyar rata tsakanin kayan tushe da turmi. .
Inganta ingancin ginin kai tsaye yana shafar tasirin hana ruwa na turmi. Tumi mai ɗaci da ƙaƙƙarfan rufin turmi na iya hana kutsawa danshi yadda ya kamata.
3. Samar da fim mai kariya na saman
HPMC yana da kaddarorin yin fim kuma yana iya samar da fim ɗin kariya na bakin ciki da ƙima a saman turmi:
Rage ƙawancen ruwa: Bayan an gama ginin, HPMC za ta samar da fim mai kariya a saman turmi don rage tsotsawar damshin cikin turmi ta wurin waje.
Toshe shigar danshi: Layer na HPMC bayan samar da fim yana da takamaiman matakin hana ruwa kuma ana iya amfani da shi azaman shamaki don hana danshi na waje shiga ciki na turmi.
Wannan kariya ta saman tana ba da ƙarin kariya ga abubuwan hana ruwa na turmi.
4. Rage porosity na turmi
HPMC na iya inganta ƙananan tsarin turmi yadda ya kamata. Tsarin aikinsa shine kamar haka:
Tasirin ciko: Kwayoyin HPMC na iya shigar da tsarin microporous a cikin turmi kuma a ɗan cika pores, don haka rage tashoshi danshi.
Haɓaka ƙaƙƙarfan samfuran hydration: Ta hanyar riƙe ruwa, HPMC yana haɓaka daidaituwa da daidaituwar samfuran hydration na siminti kuma yana rage adadin manyan pores a cikin turmi.
Rage ƙarancin turmi ba wai kawai inganta aikin hana ruwa ba, har ma yana inganta ƙarfin turmi.
5. Inganta juriyar sanyi da karko
Shigar da ruwa zai sa turmi ya lalace saboda hawan sanyi a cikin ƙananan yanayin zafi. Tasirin hana ruwa na HPMC na iya rage shigar ruwa da kuma rage lalacewar turmi da ke haifar da daskarewar hawan keke:
Hana riƙe danshi: Rage riƙe danshi a cikin turmi kuma rage tasirin sanyi.
Rayuwar turmi mai tsayi: Ta hanyar rage harin ruwa da lalacewa-narkewa, HPMC yana ƙara ƙarfin turmi na dogon lokaci.
HPMC yana haɓaka aikin turmi mai hana ruwa ta hanyar abubuwan da suka biyo baya: haɓaka riƙewar ruwa, haɓaka aikin aiki, ƙirƙirar fim mai kariya, rage porosity da haɓaka juriya na sanyi. Sakamakon synergistic na waɗannan kaddarorin yana ba da damar turmi don nuna mafi kyawun tasirin hana ruwa a aikace-aikace masu amfani. Ko a cikin turmi mai hana ruwa, turmi mai daidaita kai ko adhesives na tayal,HPMCyana taka muhimmiyar rawa.
A aikace-aikace masu amfani, adadin HPMC da aka ƙara yana buƙatar ingantawa bisa ga takamaiman buƙatu don tabbatar da cewa ba wai kawai zai iya yin tasiri mai kyau na hana ruwa ba, har ma ya kula da ma'auni na sauran alamun aikin turmi. Ta hanyar amfani da HPMC mai ma'ana, ana iya haɓaka aikin hana ruwa na kayan gini sosai kuma ana iya samar da ƙarin ingantaccen kariya don ayyukan gini.
