Redispersible latex ntụ ntụ nwere ezigbo redispersibility, redispersibility n'ime emulsion mgbe kọntaktị na mmiri, na chemical Njirimara ya fọrọ nke nta ka yiri emulsion mbụ. Ịgbakwunye emulsion latex ntụ ntụ na-esi ísì ụtọ na ciment ma ọ bụ gypsum dabeere na ntụ ntụ ntụ ntụ njikere-agwakọta ngwa agha nwere ike imeziwanye ihe dị iche iche nke ngwa agha, dị ka: imeziwanye njikọ na njikọta nke ihe; ibelata nnabata mmiri na mgbanwe mgbanwe nke ihe; ime ka ike Flexural nke ihe onwunwe dịkwuo elu, nguzogide mmetụta, eyi nguzogide na ịdịte aka; melite arụmọrụ ihe owuwu nke ihe, wdg.
Ịtinye ntụ ntụ latex na ngwa ngwa ciment ga-emepụta ihe nkiri netwọk polymer na-agbanwe nke ukwuu, nke ga-eme ka arụ ọrụ nke ngwa agha dịkwuo mma, karịsịa ike nkwụsị nke ngwa agha ga-akawanye mma. Mgbe a na-etinye ike dị n'èzí, n'ihi mmụba nke mkpokọta mkpokọta nke ngwa agha na nro dị nro nke polymer, ihe omume nke micro-cracks ga-ewepụ ma ọ bụ mee ka ọ daa.

Ogo nke ọdịda, ma ka na-emezu ihe ndị a chọrọ nke mgbidi mpụta imecha.
Ngwa ngwa ciment gwakọtara ya na ntụ ntụ latex, ike njikọ ya 28d na-abawanye na mmụba nke ọdịnaya ntụ ntụ latex. Site na mmụba nke ọdịnaya ntụ ntụ latex, a na-emeziwanye ikike ijikọ ciment ngwa ngwa na elu ciment ochie, nke na-eme ka uru ya pụrụ iche maka ịrụzi pavement ciment na ihe ndị ọzọ. Ọzọkwa, nha mpịachi nke ngwa agha na-abawanye na mmụba nke ọdịnaya ntụ ntụ latex, na mgbanwe nke ngwa agha elu na-akawanye mma. N'otu oge ahụ, na mmụba nke ọdịnaya ntụ ntụ latex, modul na-agbanwe nke ngwa agha na-ebelata na mbụ wee na-abawanye.

Ọmụmụ ihe ahụ chọpụtara na mmụba nke ọdịnaya ntụ ntụ latex, njigide na njigide mmiri nke ngwa agha na-eme ka ọ dịkwuo mma, na arụ ọrụ na-arụ ọrụ kachasị mma. Mgbe ọnụ ọgụgụ nke latex ntụ ntụ ruru 2.5%, arụ ọrụ nke ngwa agha nwere ike imezu ihe ndị a chọrọ. Ọnụ ego nke latex ntụ ntụ adịghị mkpa ka ọ dị elu, nke na-abụghị nanị na-eme ka mkpuchi mkpuchi EPS dị oke viscous ma nwee obere mmiri mmiri, nke na-adịghị akwado iwu ụlọ, ma na-abawanye ọnụ ahịa ngwa ngwa.
