Redispersible latex ufa monga chowonjezera chofunikira cha matope owuma owuma

Redispersible latex ufa ndi kubalalitsidwa kwa ufa wopangidwa ndi emulsion yosinthidwa ya polima poyanika kutsitsi. Ili ndi permeability yabwino kwambiri ndipo imatha kupangidwanso mu emulsion yokhazikika ya polima pambuyo pa kumasulidwa kwamadzi. Zomwe zimapangidwira zimafanana ndendende ndi mafuta odzola oyambira. Choncho, zimakhala zotheka kupanga matope apamwamba kwambiri a ufa wowuma, potero kupititsa patsogolo ntchito ya matope a simenti.

Redispersible latex ufa ndi chinthu chofunikira chowonjezera pamatope. Ikhoza kupititsa patsogolo ntchito yamatope, kuonjezera mphamvu yopondereza ya matope a simenti, kupititsa patsogolo mphamvu zomangira zamatope a simenti ndi matabwa osiyanasiyana, ndi kupititsa patsogolo mphamvu ya matope a simenti. Kufewa ndi kupunduka, kulimba kwamphamvu, mphamvu yopondereza, kukana abrasion, ductility, kuthamanga kwa adhesion ndi luso lotseka madzi, komanso kukhazikika. Kuphatikiza apo, ufa wachilengedwe wa latex wokhala ndi kuthamangitsa madzi ungapangitse matope a simenti kukhala ndi kukana kwabwino kwa chinyezi.

Kupititsa patsogolo mgwirizano wa matope a simenti pakupanga zomangamanga. Pambuyo mwatsopano wosakaniza matope simenti ndi zachilengedwe lalabala ufa dispersion madzi aumbike, madzi okhutira pang'onopang'ono kuchepa ndi chimbudzi ndi mayamwidwe madzi ndi m'munsi, kumwa solidification anachita, ndi evaporation ku mpweya. , tinthu tating’ono ting’onoting’ono timafika pang’onopang’ono, masambawo amazimiririka pang’onopang’ono, ndipo pang’onopang’ono amaphatikizana. Pomaliza, polima imachotsedwa. Njira yonse ya polymer demulsification imagawidwa m'malumikizidwe atatu. Mu choyambirira moisturizing emulsion, ndi polima particles ali mu mawonekedwe a Brownian zoyenda. Kusuntha momasuka, pamodzi ndi volatilization madzi, kayendedwe ka particles mwachibadwa kumvera malamulo ochulukirapo, kuthamanga kwa madzi ndi mpweya kumawalimbikitsa kuti azitha pamodzi pang'onopang'ono, gawo lachiwiri, pamene tinthu tating'ono timayamba kukhudzana, maukonde zooneka madzi volatilizes kudzera ma capillaries, ndi mkulu-porous kuthandiza mphamvu anamasulidwa pamwamba pa particles kumapangitsa mapindikidwe a masoka lalabala zigawo kuti kugwirizana pamodzi, ndi madzi otsala amadzaza pores, ndipo nembanemba mwina anapanga. . Chachitatu Chomaliza ndi kupanga kufalikira kwa mamolekyu a polima (omwe nthawi zina amatchedwa kudzimatira) kupanga filimu yeniyeni yopitilira panthawi ya demulsification.
