Njirimara ngwaahịa nke ntụ ntụ latex redispersible
1. Melite ike na-ehulata na ike mgbanwe nke ngwa agha
Ihe nkiri polymer kpụrụ site na redispersible polymer ntụ ntụ nwere ezigbo mgbanwe. A na-emepụta ihe nkiri n'ime oghere na elu nke simenti ngwa ngwa ngwa ngwa iji mepụta njikọ na-agbanwe agbanwe. Ngwa ngwa simenti dị arọ na nke na-agbaji agbawa na-aghọ ihe na-agbanwe. Mortar agbakwunyere ya na ntụ ntụ latex na-agbanwe agbanwe dị elu ọtụtụ ugboro na nkwụsi ike na ngbanwe karịa ngwa ngwa nkịtị.
2. Melite ike njikọ na njikọta nke ngwa agha
Mgbe ntụ ntụ latex redispersible dị ka ihe na-ekekọta organic ka emebere ka ọ bụrụ ihe nkiri, ọ nwere ike ịmepụta ike ike dị elu na ike njikọ dị iche iche. Ọ na-arụ ọrụ dị mkpa na ntinye nke ngwa agha na ihe ndị dị ndụ (EPS, bọọdụ ụfụfụ extruded) na ihe ndị dị n'elu ala. A na-ekesa ntụ ntụ polymer na-emepụta ihe nkiri na-ekesa n'ime usoro ngwa agha dị ka ihe na-eme ka ọ dịkwuo mma iji mee ka njikọ nke ngwa agha dịkwuo elu.
3. Meziwanye nguzogide mmetụta, ịdịte aka na iyi mgbochi nke ngwa agha
Ihe mpempe akwụkwọ rubber na-ejupụta oghere nke ngwa agha ahụ, njupụta nke ngwa agha na-abawanye, ma na-eme ka ihe mgbochi ahụ dịkwuo mma. N'okpuru omume nke ike mpụga, ọ ga-emepụta ntụrụndụ na-enweghị ebibi. Ihe nkiri polymer nwere ike ịdị na-adịgide adịgide na usoro ngwa agha.
4. Meziwanye nguzogide ihu igwe ma mee ka ngwa agha ghara ịhịa aka n'ahụ, ma gbochie ngwa agha ka ọ ghara ịgbawa.
Redispersible latex ntụ ntụ bụ resin thermoplastic nwere ezigbo mgbanwe, nke nwere ike ime ka ngwa agha nagide mgbanwe nke oyi na-ekpo ọkụ na gburugburu ebe obibi, ma gbochie ngwa agha ahụ nke ọma n'ihi mgbanwe mgbanwe okpomọkụ.
5. Meziwanye hydrophobicity nke ngwa agha ma belata mmịpụta mmiri
Na redispersible latex ntụ ntụ na-emepụta ihe nkiri na oghere na elu nke ngwa agha ahụ, na ihe nkiri polymer agaghị agbasa ọzọ mgbe ekpughere ya na mmiri, nke na-egbochi ntinye nke mmiri ma na-eme ka enweghị ike. Pụrụ iche redispersible latex ntụ ntụ nwere hydrophobic mmetụta, mma hydrophobic mmetụta.
6. Meziwanye arụmọrụ nke ihe owuwu ngwa agha
Enwere mmetụta mmanụ mmanu n'etiti ihe ndị dị na polymer roba powder, nke mere na ngwa ngwa ngwa nwere ike ịgba ọsọ n'adabereghị. N'otu oge ahụ, ntụ ntụ roba nwere mmetụta na-emepụta ihe na ikuku, na-enye mkpakọ ngwa ngwa ma na-eme ka arụ ọrụ nke ngwa agha dịkwuo mma.
