Usoro nhazi ihe nkiri nke RDP na ciment Mortar

Usoro nhazi ihe nkiri nke Redispersible Polymer Powder (RDP) na ngwa ngwa ciment gụnyere ọtụtụ usoro na-enye aka na mmepe nke ihe nkiri polymer na-ejikọta ọnụ na nke na-adịgide adịgide. Nke a bụ nkọwapụta nke usoro nhazi ihe nkiri:

1. Mgbasa: Na mbụ, a na-agbasasị akụkụ RDP n'otu n'otu n'otu oge mmiri nke ciment ngwa ngwa mix. Mgbasa a na-eme n'oge a na-agwakọta ngwakọta, ebe a na-ebute ihe ndị RDP n'ime ngwakọta ngwa agha yana ihe ndị ọzọ akọrọ.
2. Hydration: Mgbe kọntaktị na mmiri, hydrophobic polymer particles na RDP na-amalite ịza na ịmị mmiri. Usoro a, nke a maara dị ka hydration, na-eme ka ihe ndị na-emepụta polymer na-eme ka ọ dị nro ma na-enwekwu ike.
3. Nhazi ihe nkiri: Ka a na-etinye ngwakọta ngwa ngwa wee malite ịgwọ ya, ụmụ irighiri ihe RDP hydrated na-agbakọta ma jikọta ọnụ iji mepụta ihe nkiri polymer na-aga n'ihu. Ihe nkiri a na-adabere na elu nke ngwa ngwa matriks ma jikọta ihe ndị ahụ n'otu n'otu.
4. Nkwekọrịta: N'oge usoro ọgwụgwọ, ụmụ irighiri ihe RDP dị n'akụkụ na-abata na kọntaktị ma na-enweta coalescence, ebe ha na-ejikọta wee mepụta njikọ intermolecular. Usoro nkwekọrịta a na-enye aka n'ịmepụta netwọk polymer na-ejikọta ọnụ na nke na-aga n'ihu n'ime matriks ngwa agha.
5. Crosslinking: Ka ngwa ngwa ciment na-agwọ ma na-agbasi ike, njikọ kemịkalụ nwere ike ime n'etiti ụdọ polymer na ihe nkiri RDP. Usoro njikọ njikọ a na-ewusi ihe nkiri ahụ ike ma na-eme ka adhesion ya na mkpụrụ na ihe ndị ọzọ ngwa ngwa.
6. ihicha na nchikota: Ngwa ngwa ciment na-enweta ihicha na nchikota ka mmiri na-esi na ngwakọta na-agwọkwa ihe nkedo simenti. Usoro a na-enyere aka mee ka ihe nkiri RDP sie ike ma tinye ya n'ime matriks ngwa agha siri ike.
7. Nrụpụta Ihe Nkiri Ikpeazụ: Mgbe emechara usoro ọgwụgwọ ahụ, ihe nkiri RDP na-etolite nke ọma wee bụrụ akụkụ dị mkpa nke nhazi ngwa ngwa ciment. Ihe nkiri ahụ na-enyekwu ịdị n'otu, mgbanwe, na ịdịte aka na ngwa agha ahụ, na-eme ka arụmọrụ ya zuru ezu na iguzogide mgbawa, nrụrụ, na nrụgide ọrụ ndị ọzọ.

Usoro nhazi ihe nkiri nke RDP na ngwa ngwa ciment na-agụnye hydration, coalescence, crosslinking, and consolidation stages, nke na-enye aka n'ịzụlite ihe nkiri polymer na-ejikọta ọnụ na nke na-adịgide adịgide n'ime matriks ngwa agha. Ihe nkiri a na-eme ka adhesion, mgbanwe na ịdịte aka nke ngwa agha ahụ dịkwuo mma, na-eme ka arụmọrụ ya dị iche iche na-ewu ụlọ.
