Dry powder mortar ndi matope omalizidwa pang'ono opangidwa ndi zinthu zopangira mu fakitale kudzera pa batching yolondola ndi kusakaniza yunifolomu. Itha kugwiritsidwa ntchito powonjezera madzi ndi kusonkhezera pamalo omanga. Chifukwa cha mitundu yosiyanasiyana ya matope a ufa wowuma, amagwiritsidwa ntchito kwambiri. Chimodzi mwazinthu zake zazikulu ndikuti wosanjikiza wake wowonda umagwira ntchito yolumikizana, yokongoletsa, yoteteza komanso yopingasa. Mwachitsanzo, matope okhala ndi ntchito yayikulu yomangirira makamaka amaphatikiza matope omanga, matope a khoma ndi matailosi apansi, matope olozera, matope omangira, ndi zina zotero; matope omwe amakongoletsa kwambiri amaphatikizanso matope osiyanasiyana opaka pulasitala, ma putty amkati ndi kunja kwa makoma, ndi matope okongoletsa achikuda. ndi zina; matope osalowa madzi, matope osiyanasiyana osagwirizana ndi dzimbiri, matope odziyika okha pansi, matope osamva kuvala, matope otsekereza matenthedwe, matope osamva mawu, matope okonzera, matope oteteza mildew, matope otchinga, ndi zina. Chifukwa chake, mawonekedwe ake ndi ovuta, ndipo nthawi zambiri amakhala ndi simenti, filler, mineral admixture, pigment, admixture ndi zinthu zina.
1. Binder
Zida zopangira simenti zomwe zimagwiritsidwa ntchito popanga matope owuma ndi awa: simenti ya Portland, simenti ya Portland wamba, simenti yayikulu ya alumina, simenti ya calcium silicate, gypsum zachilengedwe, laimu, fume la silika ndi zosakaniza za zinthu izi. Simenti ya Portland (nthawi zambiri Type I) kapena simenti yoyera ya Portland ndizomwe zimamangiriza kwambiri. Masimenti ena apadera nthawi zambiri amafunikira mumatope. Kuchuluka kwa binder kumawerengera 20% ~ 40% yamtundu wosakaniza wowuma.
2. Wodzaza
Zodzaza zazikulu za dothi la ufa wouma ndi: mchenga wachikasu, mchenga wa quartz, miyala ya miyala ya dolomite, yowonjezera perlite, ndi zina zotero. Zodzaza izi zimaphwanyidwa, zouma, ndiyeno zimasefa mu mitundu itatu: yowopsya, yapakati, ndi yabwino. Kukula kwa tinthu tating'onoting'ono ndi: coarse filler 4mm-2mm, sing'anga filler 2mm-0.1mm, ndi filler yabwino pansi 0.1mm. Pazinthu zokhala ndi tinthu tating'onoting'ono, ufa wabwino wamwala ndi miyala ya laimu yosankhidwa iyenera kugwiritsidwa ntchito ngati kuphatikiza. Wamba youma ufa matope angagwiritsidwe ntchito osati wosweka laimu, komanso zouma ndi zotchinga mchenga monga akaphatikiza. Ngati mchenga uli wokwanira kuti ugwiritsidwe ntchito mu konkire yamapangidwe apamwamba, uyenera kukwaniritsa zofunikira pakupanga zosakaniza zowuma. Chinsinsi kubala youma ufa matope ndi khalidwe odalirika lagona pa luso la tinthu kukula kwa zipangizo ndi kulondola kwa kudyetsa chiŵerengero, amene anazindikira mu basi kupanga mzere youma ufa matope.
3. Maminolo osakaniza
The mchere admixtures wa youma ufa matope makamaka: mafakitale ndi mankhwala, zinyalala mafakitale ndi ena ores zachilengedwe, monga: slag, ntchentche phulusa, chiphala phulusa, chabwino silika ufa, etc. The zikuchokera admixtures amenewa makamaka pakachitsulo munali okusayidi calcium. Aluminiyamu hydrochloride ali mkulu ntchito ndi hayidiroliki kuuma.
4. Kusakaniza
The admixture ndi chinsinsi ulalo wa youma ufa matope, mtundu ndi kuchuluka kwa admixture ndi kusinthasintha pakati pa admixtures zimagwirizana ndi khalidwe ndi ntchito ya ufa youma matope. Pofuna kuonjezera kugwira ntchito ndi mgwirizano wa matope owuma a ufa, kupititsa patsogolo kukana kwa matope, kuchepetsa kutsekemera, ndi kupanga matope kuti asakhale osavuta kukhetsa magazi ndi kupatukana, kuti apititse patsogolo ntchito yomanga matope owuma ndi kuchepetsa mtengo wopangira. Monga ufa wa rabara wa polima, ulusi wamatabwa, hydroxymethyl cellulose ether, hydroxypropyl methyl cellulose, fiber modified polypropylene, PVA fiber ndi othandizira osiyanasiyana ochepetsera madzi.
