Tasirin foda na latexr akan sassaucin kayan aikin siminti

Redispersible latex foda zai iya inganta kaddarorin turmi irin su flexural ƙarfi da mannewa ƙarfi, domin shi zai iya samar da wani polymer fim a saman turmi barbashi. Akwai pores a saman fim ɗin, kuma saman ramukan yana cike da turmi, wanda ya rage yawan damuwa. Kuma a karkashin aikin karfi na waje, zai haifar da shakatawa ba tare da karya ba. Bugu da kari, turmi yana samar da kwarangwal mai tsauri bayan an shayar da siminti, kuma polymer din dake cikin kwarangwal yana da aikin hadin gwiwa mai motsi, wanda yayi kama da nama na jikin dan adam. Ana iya kwatanta membrane da aka kafa ta hanyar polymer da haɗin gwiwa da haɗin gwiwa, don tabbatar da elasticity da sassaucin kwarangwal. tauri.

 

A cikin tsarin turmi na ciminti da aka gyare-gyaren polymer, ci gaba da cikakken fim ɗin polymer yana haɗuwa tare da simintin siminti da ɓangarorin yashi, yana yin duk turmi mafi kyau kuma mai yawa, kuma a lokaci guda yana yin duk hanyar sadarwa ta roba ta hanyar cika capillaries da cavities. Sabili da haka, fim ɗin polymer na iya tasiri yadda ya kamata ya watsa matsa lamba da tashin hankali na roba. Fim ɗin polymer na iya haɗa ɓarnawar raguwa a cikin mahallin polymer-turmi, ya warkar da ɓarna, da inganta hatimi da haɗin kai na turmi. Kasancewar yankuna masu sassaucin ra'ayi da ƙwanƙwasa na polymer suna haɓaka haɓakawa da haɓakar turmi, suna ba da haɗin kai da ɗabi'a mai ƙarfi ga kwarangwal. Lokacin da aka yi amfani da karfi na waje, tsarin yaduwa na microcrack yana jinkirta saboda ingantacciyar sassauci da elasticity har sai an kai ga matsananciyar damuwa. Yankunan polymer ɗin da aka haɗa su kuma suna aiki azaman shinge ga haɗuwar ƙananan ƙira zuwa ratsawa. Sabili da haka, foda na polymer wanda za'a iya tarwatsawa yana inganta haɓakar rashin ƙarfi da rashin ƙarfi na kayan aiki.

 

Ƙara foda na latex zuwa turmi siminti zai samar da fim ɗin cibiyar sadarwa na polymer mai sassauƙa sosai, wanda zai inganta aikin turmi sosai, musamman ma ƙarfin ƙarfin turmi zai inganta sosai. Lokacin da aka yi amfani da karfi na waje, saboda haɓakar haɗin gwiwar gaba ɗaya na turmi da kuma laushi mai laushi na polymer, abin da ya faru na ƙananan ƙwayoyin cuta zai zama raguwa ko raguwa. Ta hanyar tasirin abun ciki na foda na latexr akan ƙarfin turmi mai rufi na thermal, an gano cewa ƙarfin haɗin gwiwa na ƙwanƙwasa mai zafi yana ƙaruwa tare da karuwar abun ciki na latex foda; Ƙarfin ƙwanƙwasa da ƙarfin matsawa yana da wani digiri tare da karuwar abun ciki na latex foda. Matsayin raguwa, amma har yanzu ya dace da bukatun bangon waje na gamawa.

 

Turmi siminti gauraye da latex foda, ƙarfin haɗin gwiwa na 28d yana ƙaruwa tare da haɓaka abun ciki na latex. Tare da karuwar abun ciki na latex foda, haɗin haɗin simintin siminti da tsohon simintin siminti yana inganta, wanda ke tabbatar da fa'idodinsa don gyara shingen siminti da sauran sifofi. Haka kuma, rabon nadawa na turmi yana ƙaruwa tare da haɓaka abun ciki na latex foda, kuma sassaucin turmi na saman yana inganta. A lokaci guda kuma, an gano cewa tare da karuwar abun ciki na latex foda, nau'in roba na turmi ya ragu da farko sannan ya karu. Gabaɗaya, tare da haɓakar tarin tarin toka, ma'aunin roƙo da nakasar turmi sun yi ƙasa da na turmi na yau da kullun.
