Redispersible latex ufa umathandizira kusinthasintha komanso kukana kwa matope

Pambuyo powonjezera ufa wa latex wopangidwanso mumatope, chiŵerengero chopindika-kuponderezedwa ndi chiwongolero cha kuponderezana kwa matope amawongoleredwa bwino kwambiri, zomwe zimasonyeza kuti kuwonongeka kwa matope kumachepetsedwa kwambiri ndipo kulimba kumakula kwambiri, kotero kuti kukana kwa matope. matope adachita bwino.

The redispersed latex ufa amataya madzi mu matope kupanga filimu, amene osati amadzaza zilema ndi pores mu mwala simenti, komanso kupanga simenti hydration mankhwala ndi aggregates mgwirizano wina ndi mzake kupanga interpenetrating maukonde ma polima. The elastic modulus ya matope ndi yotsika kuposa ya matope, kotero kuti brittleness ya matope imachepetsedwa. Kusinthasintha kwa matope kumawonjezera malire opindika kwambiri pamene matope awonongeka, ndipo amatha kuyamwa mphamvu zomwe zimafunikira pakukulitsa zolakwika ndi ming'alu yaying'ono kwambiri, kotero kuti matope amatha kupirira kupsinjika kwakukulu asanalephere. Kuonjezera apo, filimu ya polima imakhala ndi njira yodzitambasula, ndipo filimu ya polima imakhala ndi ntchito ya mgwirizano wosunthika mu mafupa okhwima omwe amapangidwa mumatope pambuyo pa simenti ya hydration, yomwe imatha kuonetsetsa kuti kusungunuka ndi kulimba kwa mafupa okhwima. Pamwamba pa filimu ya polima yomwe imapangidwa pamwamba pa matope amatope imakhala ndi pores, ndipo pamwamba pa pores imadzazidwa ndi matope, kotero kuti kupsinjika maganizo kumachepetsedwa, ndipo kumasuka popanda kuwonongeka pansi pa mphamvu ya kunja. Imawongolera kusinthasintha ndi elasticity ya matope.
