Kupaka Mitundu Yowuma ya Powder Mortar ndi Mafomula Oyambira
1. Gulu lazinthu
① Malinga ndi ntchito ya pulasitala matope, akhoza kugawidwa mu:
Nthawi zambiri, pulasitala matope akhoza kugawidwa mu matope pulasitala wamba, kukongoletsa pulasitala matope, madzi pulasitala matope ndi pulasitala matope ndi ntchito zina zapadera (monga kutchinjiriza kutentha, asidi kukana, ndi matope umboni cheza).
② Gulu molingana ndi zinthu za simenti zomwe zimagwiritsidwa ntchito mumatope opaka pulasitala
A.Kupaka matope okhala ndi zomangira zopanda organic (simenti, gypsum kapena laimu wa slaked).
B.Zokongoletsera zamtengo wapatali zogwiritsira ntchito simenti, ufa wogawanikanso kapena laimu wa slaked ngati zomangira.
C.Mapulasitala opangidwa ndi simenti amagwiritsidwa ntchito popangira kunja ndi zipinda zonyowa, pomwe zomata za gypsum zimagwiritsidwa ntchito pamakoma amkati okha.
2. Njira yolozera
Kwa matope opaka mkati ndi kunja kwa makoma a njerwa omwe si apadera, nthawi zambiri amasankha mphamvu yopondereza ya 10MPa kapena 15MPa, koma zinthu zotsika kwambiri komanso zamphamvu kwambiri zimathanso kupangidwa molingana ndi zapadera zapadera. zofunika.
Lingaliro lachilinganizo ndikuwonjezera 1% ~ 4% RE5010N ku simenti kapena laimu-simenti yopangira pulasitala, yomwe imatha kuwongolera kumamatira kwake, kukana kuvala komanso kusinthasintha.Kuphatikiza apo, tikulimbikitsidwanso kuwonjezera 0,2% ~ 0.4% ya cellulose ether, starch ether kapena osakaniza onse awiri.Ndibwino kugwiritsa ntchito redispersible polima ufa RI551Z ndi RI554Z ndi hydrophobicity kupititsa patsogolo ntchito pulasitala ndi pulasitala.
Chiyambi cha Mortar Additive Masterbatch
The matope zowonjezera masterbatch lili ndi zigawo zotsatirazi: sodium mafuta mowa polyethylene sulfonate, mapadi, sodium sulfate, wowuma efa, etc.
Ntchito zazikuluzikulu: kulowetsa mpweya, kukhuthala, kusunga pulasitiki, kupititsa patsogolo ntchito ndi zotsatira zina zapadera, mankhwala okhawo m'dzikoli omwe sasakanikirana malinga ndi kuchuluka kwa simenti.Kupulumutsa simenti mu matope osakanizidwa sikungotsimikizira mphamvu komanso kumapangitsanso kulimba, kusasunthika komanso kukana ming'alu.
Mawonekedwe ndi Magwiridwe Antchito ndi Magwiridwe Antchito ndi Magwiridwe Antchito ndi Magwiridwe:
1. Kupititsa patsogolo luso la matope ndi ntchito yabwino
Panthawi yomanga ndi pulasitala, matope amakhala ochulukirapo, ofewa, ndipo amakhala ndi mphamvu yolumikizana mwamphamvu.Malo omata samamatira pafosholo, kuchepetsa phulusa ndi mtengo wake, ndipo matope amakhala odzaza kwambiri.Zili ndi zofunikira zochepa pa mlingo wa kunyowa kwa khoma, ndipo kuchepa kwa matope kumakhala kochepa, komwe kumagonjetsa mavuto omwe amapezeka monga ming'alu, maenje, kukhetsa, ndi kutuluka thovu pakhoma, ndikuthetsa vuto la matope.Mtondo umasungidwa kwa maola 6-8 popanda sedimentation, kusungirako madzi bwino, kusalekanitsa matope mu thanki ya phulusa, komanso kusafunikira kugwedezeka mobwerezabwereza, komwe kumafulumizitsa ntchito yomanga ndikuwongolera magwiridwe antchito.
2. Mphamvu yoyambirira
Mtondo wosakanizidwa ndi zowonjezera matope uli ndi mgwirizano ndi kulimbikitsa mphamvu ndi simenti.Kupyolera mu ndondomeko ya pulasitiki, imafika pa mphamvu zina pambuyo pa maola 5-6, ndipo mphamvu yamtsogolo imakhala bwino.
3. Kupulumutsa madzi
Mtondo wokonzedwa ndi zowonjezera zamatope umakhala ndi mphamvu yolekanitsa pamadzi, yomwe ingachepetse kumwa madzi, kuchepetsa kuchepa kwa makoma opangidwa ndi pulasitala ndikuwonjezera mphamvu.
4. Ntchito zowonjezera
Mtondo wokonzedwa ndi zowonjezera zamatope umakhala ndi ntchito zosunga madzi, kuchepetsa phokoso, kuteteza kutentha, kuteteza kutentha, ndi kukana chisanu.
Kupanga ndi kupanga mapangidwe a polyvinyl acetate emulsion zomatira
