Redispersible polima ufarNthawi zambiri amagwiritsidwa ntchito pakhoma lakunja la nyumbayo ndi ufa wa putty kapena zosakaniza zina za simenti, nthawi zambiri ndi simenti ndi zosakaniza zina mkati, ndi ufa wa latex wosakanizidwa ndi putty ufa kuti upende kunja, umapatsa anthu mtundu wa Imakhala ndi zofewa. kumverera, ndipo amatha kupititsa patsogolo mphamvu ya adsorption ya matope, kuti moyo wautumiki wa khoma lakunja ukhale wautali.
Ntchito yake ikuwonekera koyamba pakuwongolera kumamatira kwa matope, chifukwa ufa wa latex udzalowa mu simenti ndikupangitsa kuti ukhale wodzaza ndi chinyezi, kotero kuti luso lomatira ndilobwino. Nthawi zambiri timakhala ndi mutu chifukwa simenti simatha kulumikizana ndi matabwa ndi ulusi ndi zida zina, koma ndi redispersible polima ufa, sitiyenera kuda nkhawa ndi chilichonse. Tonse tikudziwa kuti kukana kwa simenti kumakhala koyipa kwambiri pambuyo poumitsidwa, ndipo kuwonjezera kwa ufa wa latex kumathandizira kulimba kwake, kuti athe kupirira kupanikizika kwakukulu. Ngakhale microstructure ya konkire ya simenti idzasinthidwa ndi izo. Idzalepheretsa kuyamwa kwamadzi kwa mkati ndikuletsa madzi kuti asalowemo. Ndiye mphamvu yotsutsa-permeability ya khoma lakunja imakhalanso bwino. Palibe chifukwa chodera nkhawa kuti madzi amalowa mkati mwa nyumba pamene mvula ikugwa. Mmwamba.
Redispersible polima ufaamawonjezeredwa ku simenti, kotero kuti tinthu tating'ono ta simenti ndi fumbi zimagwirizanitsidwa mwamphamvu, kotero kuti mphamvu yonyamula katundu wamatope imakhala yabwino, ndipo kukana kuvala kumakhala kolimba. Kwa makoma akunja , Sangavute madzi mosavuta, mng'alu wouma, mapindikidwe ndi muyezo wamtundu woyenerera. Nthawi zambiri, makoma osavuta akunja a konkriti nthawi zambiri amakhala ndi moyo waufupi wautumiki, ndipo ndizosavuta kusweka pakapita zaka zingapo. Chifukwa chake, utoto wa latex umawonjezeredwa nthawi zambiri pomanga m'zaka zaposachedwa kuti awonjezere moyo wake wautumiki ndikuwonetsetsa moyo wa okhalamo. Chitetezo chaumwini ndi katundu.
Ndiye, kumeneredispersible polima ufakugwiritsidwa ntchito?Redispersible polima ufaAngagwiritsidwe ntchito m'malo otsatirawa: simenti, gypsum-based, gypsum-based, bonding matope, pulasitala matope, matope osalowa madzi, anti-cracking matope, matope okongoletsera, matope a simenti, pulasitala matope, matope a gypsum, kukonza konkire ndi kukonza Mtondo, batching. matope, matope apansi (wodzipangira okha simenti pansi, wosanjikiza pamwamba, ndi zina zotero), konkire yowuma, yosanjikiza pansi, kumanga matayala, zomatira zomangira, zomangira, zomangira, pulasitala, stucco Gypsum, mkati mwa khoma putty, kunja khoma putty, matope diatom, zokutira madzi, zokutira zosiyanasiyana,redispersible polima ufaAngagwiritsidwenso ntchito ngati plasticizers, tougheners, ndi
thickeners kwa inorganic hayidiroliki zipangizo monga simenti ndi gypsum , Binder, filimu kupanga wothandizira, madzi wothandizila.
Redispersible polima ufarali ndi izi:
1. The redispersible latex powder product ndi madzi osungunuka redispersible ufa, copolymer ya ethylene ndi vinyl acetate, ndi polyvinyl mowa monga colloid zoteteza.
2. VAE redispersible latex ufa uli ndi mawonekedwe opangira mafilimu. Njira yothetsera madzi ya 50% idzapanga emulsion, yomwe idzapanga filimu yofanana ndi pulasitiki itayikidwa pa galasi kwa maola 24.
3. Filimu yopangidwa imakhala ndi kusinthasintha kwina ndi kukana madzi. Ikhoza kufika pamiyezo ya dziko.
4. The redispersible latex ufa umakhala ndi magwiridwe antchito apamwamba: uli ndi luso lolumikizana kwambiri, magwiridwe antchito apadera komanso magwiridwe antchito osalowa madzi, mphamvu yomangirira bwino, yopatsa matope kukana kwambiri kwa alkali, ndipo imatha kupititsa patsogolo kumamatira ndi mphamvu yosunthika ya matope, Kuphatikiza pa pulasitiki. , kuvala kukana ndi kugwira ntchito, kumakhala ndi kusinthasintha kwamphamvu mumatope odana ndi ming'alu.
