Redispersible polima ufa ndi utsi-zouma ufa wa polima emulsion zochokeraethylene-vinyl acetate copolymer. Ndi chinthu chofunikira mumtondo wamakono wa drymix. Zomwe zimayambitsaredispersible polima ufamuli ndi matope omangira nyumba?
Tinthu tating'onoting'ono ta polima timadzaza matope amatope, kuchuluka kwa matope kumawonjezeka, ndipo kukana kwamadzi kumatheka. Pansi pa mphamvu yakunja, idzatulutsa mpumulo popanda kuwonongedwa. Filimu ya polima ikhoza kusungidwa kwamuyaya mumtondo.
1. Kupititsa patsogolo ntchito yomanga matope
Pambuyo redispersible latex ufa monga organic binder aumbike filimu, akhoza kupanga mkulu wamakokedwe mphamvu ndi mgwirizano mphamvu pa magawo osiyanasiyana. Imagwira ntchito yofunikira pakumatira kwamatope kuzinthu zakuthupi (EPS, bolodi la thovu lotulutsa) ndi magawo osalala apansi. Ufa wa polima wopangidwa ndi filimu umagawidwa mumatope onse ngati chinthu cholimbikitsa kuti chiwonjezere mgwirizano wa matope.
2. Limbikitsani kukana kwa nyengo, kukana kuzizira komanso kukana kwamatope
Redispersible polima ufa ndi utomoni wa thermoplastic wokhala ndi kusinthasintha kwabwino, womwe ungapangitse matope kuti athane ndi kusintha kwa kuzizira kwakunja ndi malo otentha, ndikuletsa bwino kuti matope asagwe chifukwa cha kusintha kwa kutentha.
3. Sinthani hydrophobicity ya matope ndikuchepetsa kuyamwa kwamadzi
The redispersible polima ufa umapanga filimu patsekeke ndi pamwamba pa matope, ndi polima filimu sadzabalalitsa kachiwiri pambuyo poyera madzi, amene amalepheretsa kulowerera kwa madzi ndi bwino impermeability. Wapaderaredispersible latex ufandi hydrophobic kwenikweni ali bwino hydrophobic kwenikweni.
4. Kupititsa patsogolo mphamvu yopindika ndi mphamvu yosunthika yamatope
Filimu ya polima yopangidwa ndi redispersible polima ufa imakhala yabwino kusinthasintha. Mafilimu amapangidwa mu mipata ndi pamwamba pa matope a simenti kuti apange malumikizidwe osinthika. Choncho, matope a simenti ophwanyika komanso olimba amakhala zotanuka. Mtondo wokhala ndi kuchuluka kwa ufa wa polima wotayikanso ndi wokwera kangapo kuposa matope wamba potengera kulimba komanso kupindika.
Longou compy, monga kutsogoleraRDP fakitaleku China, nthawi zonse imayang'ana pakupereka ma protucts apamwamba kwambiri komanso njira zamakonomatope a drymix. Takulandirani kuti mutiuze zambiri zakuthupi.
