1. Usoro nke omume nke redispersible latex ntụ ntụ na EPS mkpuchi ngwa agha
Dị ka ihe eji eme ihe, RDP na-emepụta ihe nkiri polymer na-aga n'ihu site na mgbasagharị n'oge usoro hydration. Ihe nkiri a nwere ike kpuchie ụmụ irighiri ihe simenti, mkpokọta dị fechaa na ihe EPS n'ime ngwa agha ahụ, si otú a na-eme ka njikọ dị n'etiti ihe ndị ahụ dịkwuo mma. Tụkwasị na nke ahụ, ihe nkiri polymer nwere ike jupụta micro-cracks na pores na ngwa ngwa, si otú ahụ na-eme ka ihe ahụ dịkwuo mma na enweghị ike.

2. Mmetụta na arụ ọrụ nke mkpuchi mkpuchi EPS
(1) Melite ike nkekọ
Iwebata RDP nwere ike imeziwanye ike njikọta nke ngwa agha mkpuchi EPS. Nhazi nke ihe nkiri polymer ọ bụghị nanị na-eme ka njikọ dị n'etiti ihe ndị dị na EPS na matriks, ma na-eme ka arụmọrụ nke njikọ dị n'etiti ngwa agha na mgbidi isi, si otú ahụ belata ihe ize ndụ nke ịwụfu na imeziwanye ike nke usoro ahụ.
(2) Mee ka mgbawa na-eguzogide
N'ihi naRDPnwere ezigbo mgbanwe, ihe nkiri polymer nke emebere ya nwere ike belata itinye uche na nchekasị nke ọma ma gbuo oge mgbasawanye nke microcracks. Nnyocha na-egosi na ike mgbanwe na ihe nhịahụ nke ngwa mkpuchi mkpuchi EPS agwakọta ya na ọnụọgụ RDP kwesịrị ekwesị na-emeziwanye nke ọma, nke na-enyere aka melite nguzogide mgbawa nke ngwa agha ahụ.
(3) Melite ịrụ ọrụ ihe owuwu
RDP nwere ike melite arụmọrụ na njigide mmiri nke EPS mkpuchi mkpuchi ma melite ahụmịhe ọrụ n'oge usoro ihe owuwu. Ngwongwo ya na-ejigide mmiri na-enyere aka igbu oge mmiri nke ngwa agha ahụ, si otú ahụ na-ahụ na oyi akwa nke ala na-eme ka mmiri dị ọcha ma na-eme ka ike mbụ dịkwuo mma.
(4) Mee ka ịdịte aka dịkwuo elu
Mgbochi mmiri na kemịkalụ nke ihe nkiri RDP na-eme ka nkwụsi ike nke ifriizi na nguzogide carbonation nke ngwa mkpuchi EPS. Nke a dị oke mkpa maka ịrụ ọrụ ogologo oge nke ihe.
(5) Mgbanwe agafeghị oke na njupụta
Iwebata RDP enweghị mmetụta dị nta na njupụta nke ngwa agha, mana mmelite nke ike mkpakọ chọrọ ịchịkwa usoro onunu ogwu. Oke RDP nwere ike iduga mbelata nke nguzogide mkpakọ, ya mere oke kwesịrị ka emeziwanye ya nke ọma ka ọ na-eju akụrụngwa ndị ọzọ.
3. Injinia mkpa
N'ime ngwa injinia n'ezie, ngwa mkpuchi mkpuchi EPS kwesịrị inwe ma mkpuchi ọkụ dị mma yana akụrụngwa akụrụngwa, ebe ọ na-emezu ihe achọrọ nke owuwu dị mfe yana ịdịte aka dị elu. Dị ka ihe mgbanwe isi, uzuzu latex na-agbanwe agbanwe na-enye ọtụtụ ngwọta kachasị mma maka ngwa mkpuchi EPS. N'otu aka ahụ, ngwa nke RDP na-eme ka adhesion na nkwụsị mgbawa nke ngwa agha ahụ dịkwuo mma ma na-ebelata ihe ize ndụ nke mkpuchi mkpuchi na-adapụ na mgbawa; N'aka nke ọzọ, ọganihu ya na arụmọrụ ihe owuwu na ịdịte aka nke ngwa agha ahụ na-eme ka EPS mkpuchi mkpuchi dị mma maka ọrụ nchekwa nchekwa ụlọ dị elu.
ntụ ntụ latex enwere ike agbasanwere ike imeziwanye arụmọrụ njikọta, mgbape mgbape, arụmọrụ ihe owuwu na ịdịte aka nke ngwa mkpuchi mkpuchi EPS site n'ịme ihe nkiri polymer. N'ime ngwa injinia, njikarịcha usoro onunu ogwu na ojiji nke RDP nwere ike nweta nguzozi kachasị mma nke akụrụngwa. Nchọpụta ga-eme n'ọdịnihu nwere ike nyochaa mmekọrịta dị n'etiti RDP na ndị ọzọ na-agbanwe agbanwe iji gboo mkpa nke mkpuchi mkpuchi ọkụ na ọnọdụ dị iche iche.
