1. Kayan jiki da sunadarai na HPMC
HPMC shine polymer mai narkewa ta hanyar methypypypypypypypypy da hydroxypropypypypypyation na sel na halitta. Hydroxypropyl da metyl masu maye gurbin kungiyoyi na kwayar halitta ƙayyade ƙididdigar ta, riƙewar ruwa da kaddarorin ruwa a cikin mafita. HPMC za'a iya narkar da shi a cikin ruwan sanyi don samar da mafita mai sauƙi ko kalmar wucewa ta Colloidal tare da babban danko.
Riƙewa ruwa
HPMC yana da riƙewar mai riƙe ruwa kuma yana iya rage asarar ruwa cikin inganci a kankare. Dingara adadin da ya dace na HPMC zuwa matsayin hadari na kankare na iya kula da rarraba ruwa a cikin tsarin gel, don haka inganta ingancin hydrete. Kyakkyawan riƙe ruwa mai kyau yana taimakawa hana fashewa da ɓarna na kankare saboda asarar ruwa yayin hardening, kuma haɓaka ƙimar kankare.
Thickening da filastik
HPMC kuma tana taka rawa a cikin thickening da kuma filastik a kankare. Kungiyoyi na hydroxypyl da metyl ƙungiyoyi a cikin kwayoyin jikin sa na iya samar da shaidu na ruwa, da kuma sanya kankare na kankare da kaddarorin rabuwa. Wannan tasirin thickening yana taimaka wa kankare yana kula da ingantaccen ruwa da yawa yayin ginin. Bugu da kari, HPMC na iya yin aiki a matsayin filastik na filastik, rage ragin sarkin ruwa-ciminti na ruwa, da inganta ƙarfi da yawa na kankare.
Fim-samar da dukiya
HPMC na iya samar da wani yanki mai kyau fim a cikin maganin ruwa mai ruwa, kuma wannan kayan samar da fim ɗin yana da mahimmancin aikace-aikace a kankare.

Wannan fasalin yana da mahimmanci musamman don kariya ta kankare da haɓaka ƙarfin juriya.
2. Tasirin aikace-aikacen HPMC a cikin kankare
Inganta juriya
Jin juriya da kankare shine muhimmiyar nuna alama don auna ƙarfinsa. HPMC rijiyar riƙe ruwa da tasirin tashin hankali na iya rage shrinkage da shrinkage na kankare yayin wahala, don ta rage yiwuwar fasa fasa. Ta hanyar bincike na gwaji, an gano cewa fashewar juriya da HPMC ya kara da kyau fiye da na talakawa.
Ingantaccen ƙarfin ƙarfi
HPMC kuma yana da tasirin haɓaka ƙarfin rikitarwa a kankare. Wannan yafi ne saboda HPMC na iya inganta daidaituwa na kankare, rage ɓoyayyen ciki da lahani, kuma don haka inganta yawan kankare. Bugu da kari, da Preent sakamakon HPMC yana rage raguwar ciminti na kankare. A karkashin yanayin rabo iri ɗaya-ciminti, kankare tare da HPMC ya kara da karfi sosai.
Ingantaccen aikin gini
Da thickening da kuma samar da kayan aikin HPMC na inganta aikin gini na kankare. A yayin aikin ginin, HPMC na iya ƙara danko na kankare, hana rarrabuwa da zub da jini na kankare, kuma tabbatar da daidaituwa na kankare. A lokaci guda, mallakar kayan fim na HPMC na iya samar da fim mai kariya a mataki na gaba na aikin gini don hana saurin kankare.
Inganta karkara
Riƙewa ta ruwa da tasirin samar da kayan aikin HPMC na taimakon hpmc na neman lafazin kula da kyakkyawan yanayin a karkashin yanayin muhalli, don inganta ƙarfin kankare. Ta hanyar samar da fim mai kariya, HPMC na iya rage fitar da ruwa a saman kankare da kuma rage lalacewa na kankare da yanayin waje. Musamman a cikin wurare masu sanyi, HPMC na iya hana shimfidawa na ƙasa da kuma ƙwayoyin cuta wanda ya haifar da daskarewa-diwze.
3. Misalin Aikace-aikacen HPMC a cikin kankare
A cikin aikace-aikacen injiniya na ainihi, ana amfani da HPMC sosai a samfurori daban-daban da ayyukan ginin. Misali, a cikin kayan da kai na kai, hpmc na iya samar da kyawawan rai da ikon matakin kai, da kuma inganta lebur da na bene. A cikin shirye-hade na hade, HPMC za a iya amfani dashi azaman mai rike ruwa da bashin don inganta aikin ginin da kuma ƙwararren na kankare. Bugu da kari, ana amfani da HPMC a cikin kayan kamar bushe bushe, da kayan grouting don yin kyakkyawan riƙewar ruwa da tasirin ruwa.
A matsayin kayan aiki, HPMC yana da tasiri sosai wajen inganta aikin kankare. Riƙe mai ruwanta, thickening, samar da fim da filayen da aka kunna da muhimmanci sosai inganta ƙarfin juriya, mai rikitarwa da karkowar a kankare. Tare da ci gaba da ci gaban fasahar gini na kayan gini, masu aikin aikace-aikacen HPMC a cikin kankare zasu zama mai yawa, suna samar da wani sabon shugabanci don bincike da ci gaba da manyan ayyukan kayan aiki.
