Usoro arụrụ arụ nke ntụ ntụ polymer na-agbanwe agbanwe

polymer ntụ ntụ redispersible (RDP) bụ ihe eji eme ihe n'ọtụtụ ebe n'ụdị ngwa agha drymix. Isi ọrụ nke RDP bụ imeziwanye ike njikọta, ịrụ ọrụ, na ịdịte aka nke ngwa ngwa drymix.

Usoro nke RDP na ngwa agha drymix gụnyere ọtụtụ usoro:

1. Nhazi ihe nkiri: Mgbe agbakwunyere RDP na ngwa ngwa drymix, ọ na-emepụta ihe nkiri n'elu akụkụ nke ngwakọta akọrọ. Ihe nkiri a na-enyere aka ịbawanye nchikota n'etiti ihe ndị ahụ ma melite ike njikọ nke ngwa agha.
2. Plasticization: RDP na-arụkwa ọrụ dị ka plasticizer na drymix ngwa agha, nke pụtara na ọ na-enyere aka melite workability na nhazi nke ngwakọta. A na-enweta nke a site n'ibelata viscosity nke ngwakọta na ime ka ọ dịkwuo mfe ịgwakọta na itinye.
3. Njide mmiri: RDP nwere ike ịmịnye ma jide n'elu mmiri, nke na-enyere aka mee ka ngwa ngwa hydrated na-arụ ọrụ ruo ogologo oge. Nke a dị mkpa karịsịa na ngwa agha drymix nke kwesịrị ibufe ma chekwaa ogologo oge.
4. Mgbanwe: RDP nwekwara ike melite mgbanwe na ịdịte aka nke drymix mortars. A na-enweta nke a site n'ịkwalite ngbanwe na ike nke ngwakọta, nke na-enyere aka belata ohere nke mgbawa na ụdị mmebi ndị ọzọ.

N'ozuzu, usoro ọrụ nke RDP na drymix motar dabeere na ike ya ịmepụta ihe nkiri, mee ihe dị ka plasticizer, na-ejigide mmiri, na-eme ka mgbanwe na ịdịte aka nke ngwakọta. Ngwongwo ndị a na-eme ka RDP bụrụ ihe mgbakwunye dị mkpa maka imeziwanye arụmọrụ na ịdị mma nke ngwa agha drymix.
