Uduce twometseho ifu (DMM) ni ibikoresho by'ubwubatsi bikozwe mu kumisha no gusya sima, gypsum, lime, nibindi nk'ibikoresho by'ibanze, nyuma yo kubigereranya neza, bongeramo ibintu bitandukanye bikora neza n'ibisuzumisha. Bifite ibyiza byo kuvanga byoroshye, kubaka byoroshye, kandi bifite ubuziranenge buhamye, kandi bikoreshwa cyane mu bwubatsi, mu buhanga bwo gushushanya no mu bindi bikorwa. Ibice by'ingenzi bya uduce twometseho ifu birimo ibikoresho by'ibanze, ibisuzumisha, ibivange n'ibindi. Muri byo,eteri ya selulose, nk'inyongeramusaruro y'ingenzi, igira uruhare runini mu kugenzura imikorere y'imitsi no kunoza imikorere y'inyubako.
1. Ibikoresho by'ibanze
Ibikoresho by'ibanze ni byo bigize sima yumye, ubusanzwe harimo sima, gypsum, lime, nibindi. Ubwiza bw'ibikoresho by'ibanze bigira ingaruka zitaziguye ku mbaraga, gufatana, kuramba n'ibindi bintu by'isima yumye.
Sima: Ni kimwe mu bikoresho by'ibanze bikunze gukoreshwa mu ibumba ry'uruvange rw'uruvange rw'uruvange, akenshi sima isanzwe ya silicate cyangwa sima yahinduwe. Ubwiza bwa sima ni bwo bugena imbaraga za sima. Ingano zisanzwe z'imbaraga ni 32.5, 42.5, n'ibindi.
Gypsum: ikoreshwa cyane mu gukora sima ya plaster na sima yihariye yo kubaka. Ishobora gutuma sima ifunga neza kandi igakomera mu gihe cyo kunywa amazi no kunoza imikorere ya sima.
Lime: ikoreshwa muri rusange mu gutegura imashini zidasanzwe, nka lime mortar. Gukoresha lime bishobora kongera amazi mu imashini no kongera ubushobozi bwo kurwanya ubukonje.
2. Icupa ry'amajwi
Ifu y'ibumba ivuga ifu idakomoka ku bimera ikoreshwa mu guhindura imiterere y'ibumba, ubusanzwe harimo umusenyi mwiza, ifu ya quartz, perlite yagutse, ceramsite yagutse, nibindi. Ibi byuzuza ubusanzwe biboneka binyuze mu buryo bwihariye bwo gusuzuma bufite ingano imwe y'uduce kugira ngo harebwe imikorere y'ibumba. Inshingano y'ibumba ni ugutanga ingano y'ibumba no kugenzura uburyo ritemba n'uburyo rifatana.
Umucanga muto: ukunze gukoreshwa mu gishishwa cyumye gisanzwe, gifite uduce duto, ubusanzwe kiri munsi ya mm 0.5.
Ifu ya Quartz: ifite ubuziranenge bwinshi, ikwiriye amasafuriya akeneye imbaraga nyinshi kandi aramba.
Perlite/ceramsite yagutse: ikoreshwa cyane mu byuma byoroheje, bifite ubushobozi bwo gukingira urusaku n'ubushyuhe.
3. Ibivanze
Ibivange ni ibintu bya shimi byongera imikorere ya mortilage yumye, cyane cyane ibifata amazi, ibigabanya ubushyuhe, ibirwanya ubukonje, nibindi. Ibivange bishobora guhindura igihe cyo gushyiraho, uburyo amazi anyuramo, uburyo amazi agumana, nibindi bya mortilage, no kunoza imikorere y’ubwubatsi n’ingaruka z’ikoreshwa rya mortilage.
Ikintu kibungabunga amazi: gikoreshwa mu kunoza uburyo amazi abikwamo mu cyuma no gukumira amazi guhindagurika vuba cyane, bityo kikongera igihe cyo kubaka cyuma, ibyo bikaba ingenzi cyane, cyane cyane mu bushyuhe bwinshi cyangwa ahantu humutse. Ibintu bikunze kubungabunga amazi birimo polymer.
Ibisubizo: bishobora gutinza igihe cyo gushyiraho sima, biberanye n'ubushyuhe bwinshi mu kubaka kugira ngo birinde sima gukomera imburagihe mu gihe cyo kubaka.
Ibikoresho byo kwihutisha: byihutisha uburyo bwo gukomera kwa sima, cyane cyane mu bushyuhe buke, bikunze gukoreshwa mu kwihutisha uburyo sima ikura amazi no kunoza imbaraga za sima.
Antikonjesha: ikoreshwa mu bushyuhe buke kugira ngo hirindwe ko morti idatakaza imbaraga bitewe no gukonjesha.
4. Inyongeramusaruro
Inyongeramusaruro yerekeza ku bintu bya chimique cyangwa karemano bikoreshwa mu kunoza imiterere imwe n'imwe ya mortivali y'uruvange rw'ibintu byumye, ubusanzwe harimo eteri ya cellulose, thickener, dispersant, nibindi. Cellulose ether, nk'inyongeramusaruro ikoreshwa cyane, igira uruhare runini muri mortivali yumye.
Uruhare rwa eteri ya selulosi
Cellulose ether ni ubwoko bw'ibinyabutabire bya polymer bikozwe muri cellulose binyuze mu guhindura imiti, bikoreshwa cyane mu bwubatsi, gusiga irangi, imiti ya buri munsi n'ibindi bikorwa. Mu ibumba ry'uruvange rw'ibintu byumye, uruhare rwa cellulose ether rugaragarira cyane cyane muri ibi bikurikira:
Kunoza uburyo amazi abikwa muri morti
Eteri ya selulosi ishobora kongera neza uburyo amazi abikwa muri mortilage no kugabanya amazi asohoka vuba. Imiterere yayo ya molekile irimo amatsinda akunda amazi, ashobora gukora imbaraga zikomeye zo gufatana na molekile z'amazi, bityo bigatuma mortilage igumana ubushuhe kandi ikirinda kwangirika cyangwa ingorane zo kubaka ziterwa no kubura amazi vuba.
Kunoza imiterere y'imitsi ya morti
Cellulose ether ishobora guhindura uburyo mortillage ifatana n'uburyo ifatana, bigatuma mortillage irushaho kuba imwe kandi yoroshye kuyikoresha mu gihe cyo kubaka. Yongera ubukana bwa mortillage binyuze mu kuyigabanya, yongera uburyo irwanya gutandukanya, ikarinda mortilla gutandukana mu gihe cyo kuyikoresha, kandi ikagenzura ubwiza bw'mortillage.
Ongera uburyo bwo gufatana kwa mortiweri
Firimu ikorwa na eteri ya cellulose muri mortila ifite uburyo bwo gufatana neza, bifasha kunoza imbaraga zo gufatana hagati ya mortila na substrate, cyane cyane mu kubaka no gushyiramo amatafari, ishobora kunoza neza imikorere yo gufatana no kwirinda kugwa.
Kunoza uburyo bwo kurwanya imipfundo
Gukoresha eteri ya selulosi bifasha kunoza ubudahangarwa bw'imyanda ya mortiweri, cyane cyane mu gihe cyo kumisha, eteri ya selulosi ishobora kugabanya imyanda iterwa no gucika kw'imyanda binyuze mu kongera imbaraga n'ubukana bya mortiweri.
Kunoza imikorere y'ubwubatsi bwa sima
Eteri ya selulosiishobora guhindura neza igihe cyo kubaka sima, ikongera igihe cyo gufungura, kandi igatuma ikomeza gukora neza mu gihe cy'ubushyuhe bwinshi cyangwa humutse. Byongeye kandi, ishobora no kunoza uburyo sima ikora neza kandi ikananoza ubwiza bw'inyubako.
Nk'ibikoresho by'ubwubatsi bikoresha neza kandi bitangiza ibidukikije, ubushishozi bw'imiterere yabyo n'ingano yabyo bigena ubwiza bw'imikorere yabyo. Nk'inyongeramusaruro y'ingenzi, eteri ya selulose ishobora kunoza imiterere y'ingenzi ya selulose yumye, nko kubika amazi, rheology, no gufatana, kandi igira uruhare runini mu kunoza imikorere y'ubwubatsi n'ubwiza bwa selulose. Uko inganda z'ubwubatsi zikomeza kongera ibisabwa kugira ngo zikore neza, ikoreshwa rya eteri ya selulose n'izindi nyongeramusaruro mu selulose yumye bizarushaho kuba byinshi, bitange umwanya munini ku iterambere ry'ikoranabuhanga ry'inganda.
