Inzu ya sima yo mu rugo hamwe na HPMC
Ibigize:
Ibice 4 sima ya Portland
Ibice 4 umucanga
Ibice 4 amabuye cyangwa amabuye yajanjaguwe
Igice 1 HPMC (Hydroxypropyl Methylcellulose)
Amazi (nkuko bikenewe)
Amabwiriza:
Mu kintu kinini cyangwa kuvanga igituba, komatanya sima ya Portland, umucanga, na kaburimbo / amabuye yajanjaguwe ku kigereranyo cya 4: 4: 4.Iri gereranya ryerekana kuvanga kuringaniza sima ikomeye kandi iramba.
Kuvanga neza ibikoresho byumye hamwe ukoresheje amasuka cyangwa igikoresho cyo kuvanga kugeza bihujwe neza hanyuma bigakora imvange imwe.Ibi bizemeza ko sima ifite imbaraga zihamye kandi ziramba.
Mubikoresho bitandukanye, vanga HPMC namazi.Umubare usabwa wa HPMC ugomba kongerwaho mubisanzwe 0.2% kugeza 0.3% kuburemere bwuruvange rwumye.Kubara umubare ukenewe wa HPMC ukurikije uburemere bwa sima ivanze.Kurugero, niba ufite ikiro 1 cyuzuye cyo kuvanga, wakongeramo garama 2 kugeza kuri 3 za HPMC.
Buhoro buhoro usuke HPMC ivanze mubintu byumye mugihe ukomeje kuvanga.Buhoro buhoro ongeramo amazi nkuko bikenewe hanyuma ukomeze kuvanga kugeza igihe ivangwa rigeze kumurongo uhoraho.Witondere kutongeramo amazi menshi, kuko ashobora kugabanya imbaraga za sima.
Kuvanga neza imvange yose muminota mike kugeza ibiyigize byose bigabanijwe neza kandi ibyifuzo bikenewe bigerwaho.Isima igomba gufata imiterere yayo mugihe ikozwe mumupira ariko ikomeza kuba nziza kuburyo bworoshye kuyikoresha.
Isima imaze kuvangwa no kwifuzwa, iba yiteguye gukoreshwa.Koresha sima hejuru yifuzwa ukoresheje trowel, urebe neza no gukwirakwizwa no guhuza neza.
Emerera sima gukira no gukomera ukurikije amabwiriza yabakozwe.Ibi mubisanzwe bikubiyemo kubika sima kubitwikiriye umwenda utose cyangwa urupapuro rwa plastike muminsi mike.Gukira bihagije ni ngombwa kuri sima kugirango igere ku mbaraga nini kandi iramba.
Icyitonderwa: Umubare wa HPMC urashobora gutandukana bitewe nibisabwa byihariye cyangwa ibyifuzo byabakora.Nibyiza kugisha inama urupapuro rwibicuruzwa cyangwa kwegera uruganda rwa HPMC kugirango ubone amabwiriza asobanutse ku kigero gikwiye cya HPMC yongerwa kuri sima ivanze.
Wibuke gukurikiza ingamba zose z'umutekano hamwe nubuyobozi mugihe ukorana na sima, harimo kwambara imyenda ikingira, gants, na goggles, no kwemeza guhumeka neza aho ukorera.
Ishimire gukoresha sima yawe murugo hamwe ninyungu ziyongereye za HPMC, zishobora kuzamura imikorere nibikorwa rusange mubikorwa bitandukanye!
