Udindo wawobwezeredwapolymerpawudaMu ufa wa putty: ili ndi zomata zamphamvu komanso zamakina, zosokoneza, zosokoneza, komanso kukana bwino ma alkali komanso kuthana ndi kukana, ndipo zimatha kusintha kusungidwa kwamadzi ndikuwonjezera nthawi yotseguka.
1. Zotsatira za matope osakanizika
1) Sinthani zomanga.
2) Kusunga kwamadzi kowonjezereka kusinthira ma simemer hydration.
3) Kuchulukitsa.
4) Pewani kutsutsana.
2. Mphamvu ya matope owuma
1) Chepetsani matopu a matongu ake ndikuwonjezera kuyenderana ndi malo osanjikiza.
2) Kuchulukitsa kusinthasintha ndikupewa kusweka.
3) Sinthani kukana kwa ufa.
4) Hydrophobic kapena kuchepetsa kuyamwa kwa madzi.
5) Kuchulukitsa komatira ku malo osanjikiza.
Ufa wokwezeka wa latx umapanga emulsion polima ndi madzi. Mukasakanikirana ndi kuyanika, emulsion imadzichepetsedwa. Ufa wa latex umachita ufa wa putty, ndipo njira yopanga dongosolo ya simenti ya simenti ndi mafilimu a latax ufa imamalizidwa m'masitepe anayi:
①wn ufa wokwezedwa wa latx umasakanizidwa kwambiri ndi madzi mu ufa wa putty, umabalalitsidwa kukhala ma tinthu tating'onoting'ono;
② simenti ya simenti pang'onopang'ono imapangidwa pang'onopang'ono hydration ya simenti, gawo lamadzi limakhala ndi ca (o) 2) Sitementi yosasunthika site yosakaniza;
③ Monga simenti imatsitsidwanso, madzi m'mapazi a capillary amachepetsa, ndipo pang'onopang'ono tinthu tating'onoting'ono timakhala pang'onopang'ono pamtunda wa simenti gelement.
④ Pochitapo kanthu kazinthu hydrate zomwe zimasanjikiza ndi mawonekedwe osanjikiza, chinyontho chimachepa, ndipo zitsulo zopangidwa zimaphatikizidwa mufilimu yopyapyala, ndipo zopangidwa ndi ma netrine zimangiririka. Dongosolo lopangidwa ndi simenti hydration ndi mafilimu a latex ufa limasintha motsutsana ndi kusokonekera kwapamwamba.
Kuchokera pakugwiritsa ntchito ntchito yothandiza, mphamvu ya patenyo imagwiritsidwa ntchito ngati kusintha kwa mawonekedwe akunja ndipo zokutidwa ndi khoma lakunja siziyenera kukhala zapamwamba kuposa za matope opaka, apo ayi ndizosavuta kutulutsa kusokonekera. Mu kachitidwe konse, kusinthasintha kwa maziko kuyenera kukhala apamwamba kuposa gawo lapansi. Mwanjira imeneyi, kukhazikika kumatha kusinthabwino kuwonongeka kwa gawo lapansi ndi kuyika kuwonongeka kwake mothandizidwa ndi zinthu zakunja, kumathandizira kupsinjika, ndikuchepetsa kuthekera kwa zokutira.
