Masonry Mortars

Zida za QualiCell cellulose ether HPMC/MHEC zimatha kupanga simentiyo kukhala ndi madzi okwanira, kuonjezera mphamvu zomangira, komanso kuonjezera mphamvu zamakokedwe zomangira ndikumeta ubweya wa matope owumitsa.Pakadali pano, imatha kuwongolera magwiridwe antchito ndi mafuta, kuwongolera kwambiri ntchito yomanga ndikuwongolera magwiridwe antchito.

Ma cellulose ether a Masonry Mortar

Masonry mortar amatanthauza matope omwe njerwa, miyala, ndi zida zomangira zimamangidwiramo.Imagwira ntchito ngati chipika chomangika, konkire ndi kutumiza mphamvu, ndipo ndi gawo lofunikira la matope a simenti.Njerwa za simenti zimagwiritsidwa ntchito pomanga zomanga ndi zofunika kwambiri pa chilengedwe cha simenti ndi mphamvu.Nsalu za njerwa nthawi zambiri zimagwiritsa ntchito matope a simenti okhala ndi giredi lamphamvu la 5 mpaka M10;Maziko a njerwa nthawi zambiri amagwiritsa ntchito matope a simenti omwe si a M5;nyumba zotsika kapena ma bungalows amatha kugwiritsa ntchito laimu matope;zomangira zosavuta, laimu dongo matope, angagwiritsidwe ntchito.

Simenti ndiye chinthu chachikulu chomangira matope.Simenti zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo simenti, simenti ya slag, simenti ya pozzolan, simenti ya ntchentche ndi simenti yamagulu, ndi zina zotero, zomwe zingasankhidwe malinga ndi zofunikira za mapangidwe, njerwa zamatabwa ndi malo a chilengedwe.Simenti yamphamvu imatha kukwaniritsa zofunikira.

Mphamvu ya simenti yogwiritsidwa ntchito mumchenga wa simenti sayenera kupitirira 32.5;mphamvu ya simenti yomwe imagwiritsidwa ntchito mumatope osakanikirana a simenti sayenera kupitirira 42.5.Ngati mulingo wa simenti ndi wokwera kwambiri, mutha kuwonjezera zida zosakanikirana.Pazifukwa zina zapadera, monga kukonza zolumikizira ndi zolumikizana zamagulu, kapena kulimbikitsa ndi kukonza ming'alu, simenti yokulirapo iyenera kugwiritsidwa ntchito.Zida za simenti zomwe zimagwiritsidwa ntchito mumatope omanga ndi monga simenti ndi laimu.Kusankhidwa kwa mitundu ya simenti ndikofanana ndi konkriti.Simenti ya simenti iyenera kukhala nthawi 45 kuposa mphamvu ya matope.Ngati simentiyo ndi yochuluka kwambiri, simentiyo imakhala yosakwanira, zomwe zimapangitsa kuti madzi asasungidwe bwino.Phala la laimu ndi laimu wa slaked samangogwiritsidwa ntchito ngati zipangizo zopangira simenti, koma chofunika kwambiri, chimapangitsa kuti matope azikhala ndi madzi abwino.Fine aggregate Kuphatikizika bwino kumakhala mchenga wachilengedwe, ndipo matope okonzedwawo amatchedwa matope wamba.Dongo lomwe lili mumchenga lisapitirire 5%;pamene kalasi ya mphamvu ndi yochepa kuposa m2.5, dongo la dongo siliyenera kupitirira 10%.Kukula kwakukulu kwa mchenga kuyenera kukhala kosakwana 1/41/5 wa makulidwe a matope, nthawi zambiri osapitirira 2.5 mm.Monga matope kwa grooves ndi pulasitala, pazipita tinthu kukula si upambana 1.25 mm.Kuchuluka kwa mchenga kumakhudza kwambiri kuchuluka kwa simenti, kugwira ntchito, mphamvu ndi kuchepa.
