RDP ntụ ntụ bụ ntụ ntụ mmiri na-acha ọcha ma ọ bụ na-acha ọcha nke na-eme ka mmiri dị ọcha na-eme ka emulsion pụrụ iche dabere na mmiri.
RDP ntụ ntụ na-emepụta ihe nkiri mgbe ọ gbasasịrị ma na-eme ihe dị ka nrapado nke abụọ.Tọ na-etinye colloid nchebe site na usoro ngwa agha (mmiri agaghị emebi ya mgbe emechara ihe nkiri ahụ, ma ọ bụ "mgbasa nke abụọ").Tọ na-emepụta ihe nkiri polymer resinana ihe na-agba ume, a na-ekesa ya na usoro ngwa agha dum, si otú ahụ na-abawanye njikọ, tọ compressive ike na mgbanwe ike nke ngwa agha.
Ihe mgbakwunye nkeRDP ntụ ntụ na elongation nke ngwa agha na-eme ka mmetụta siri ike nke ngwa agha dịkwuo mma, ma na-enyekwa ngwa agha ahụ mmetụta mgbasawanye nrụgide.Usoro njikọ ahụ na-adabere na mgbasa ozi na mgbasa nke nnukwu ụmụ irighiri ihe n'elu nnyapade.
N'otu oge ahụ, ndịRDP nwere ogo nke permeability.Ya na cellulose ether, ọ na-abanye n'ụzọ zuru ezu n'elu elu nke isi ihe, nke mere na oyi akwa na elu nke plasta ọhụrụ dị nso na arụmọrụ elu, si otú a na-eme ka ọrụ ya dịkwuo ukwuu.Belata modul na-agbanwe nanrụrụ-ike nke ngwa agha, ma belata mgbawa.
Nguzogide abrasion nke ngwa agha ahụ:
Mgbochi abrasion bụ n'ihi ọnụnọ nke obere gluu na elu nke ngwa agha ahụ.The roba ntụ ntụ na-arụ ọrụ dị ka ihe njikọ.Ọdịdị ntupu nke ntụ ntụ rọba kpụrụ nwere ike ịgafe n'oghere na mgbawa dị na ngwa simenti.Meziwanye njikọ nke isi ihe na ngwaahịa hydration ciment, si otú a na-emeziwanye nguzogide abrasion.Nye ngwa agha ihe mgbochi alkali dị mma.
Ọrụ nkeRDP ntụ ntụ na putty, ngwa agha na tile gluu:
Ime na mpụga mgbidi putty ntụ ntụ, tile nrapado, tile jointing gị n'ụlọnga, akọrọ ntụ ntụ interface gị n'ụlọnga, mpụga mgbidi mpụga thermal mkpuchi ngwa agha, onwe-leveling ngwa agha, ndozi ngwa agha, ji achọ ngwa agha, waterproof ngwa agha na mpụga thermal mkpuchi akọrọ-agwakọta ngwa agha.It bụ imeziwanye mgbakasị ahụ na modulus dị elu nke ngwa ngwa ciment ọdịnala, ma nyekwa ngwa ngwa ciment ka mma mgbanwe na ike njikọta ike iji guzogide na igbu oge ọgbọ nke ụrọ ciment.N'ihi na polymer na ngwa agha na-etolite usoro netwọk mmekọrịta, a na-emepụta ihe nkiri polymer na-aga n'ihu na pores, nke na-eme ka njikọ dị n'etiti nchịkọta dị ike ma na-egbochi ụfọdụ pores na ngwa agha.Ya mere, ngwa agha a na-agbanwe agbanwe na-eme ka obi sie ike na-arụ ọrụ dị mma karịa ngwa ngwa ciment.Enwere ọganihu dị ukwuu.
Ọrụ nkeRDP ntụ ntụ na putty bụ tumadi na akụkụ ndị a:
1. Adhesion na n'ibu Njirimara nke putty.RDPbụ ihe nkedo ntụ ntụ mere site na emulsion pụrụ iche (polima molecular) nke a na-efesa.Nke a ntụ ntụ nwere ike ngwa ngwagbasasịa ọzọ n'ime emulsion mgbe ọ na-akpakọrịta na mmiri, na nwere otu ihe onwunwe dị ka emulsion mbụ, ya bụ, a film nwere ike kpụrụ mgbe mmiri evaporates.Ihe nkiri a nwere nnukwu mgbanwe, elu ihu igwe na-eguzogide na-eguzogide dị iche iche High adhesion na mkpụrụ.Tụkwasị na nke ahụ, uzuzu mmiri na-eme ka mmiri na-eme ka mmiri na-eme ka mmiri ghara ịdị mma.
2. Njikọ nke putty, nguzogide dị mma, nguzogide alkali, nkwụsi ike abrasion, na ike na-agbanwe agbanwe.
3. Waterproof na permeability nke putty.
4. Njide mmiri nke putty, na-abawanye oge na-emeghe, na ịrụ ọrụ.
5. Mmetụta mmetụta nke putty na nkwalite ike nke putty.
Ọrụ nkeRDP ntụ ntụ na ngwa agha bụ tumadi na akụkụ ndị a:
1. Ike mkpakọ na ike mgbanwe nke ngwa agha.
2. Mgbakwunye nke latex ntụ ntụ na elongation nke ngwa agha ahụ na-eme ka mmetụta siri ike nke ngwa agha dịkwuo mma ma na-enyekwa ngwa agha ahụ mmetụta mgbasawanye nrụgide.
3.

4. Belata modul na-agbanwe agbanwe nanrụrụ-ike nke ngwa agha ma belata mgbawa.
5. Yiri mgbochi nke ngwa agha.Mgbochi abrasion bụ n'ihi ọnụnọ nke obere gluu na elu nke ngwa agha ahụ.The roba ntụ ntụ na-arụ ọrụ dị ka ihe njikọ.Ọdịdị ntupu nke ntụ ntụ rọba kpụrụ nwere ike ịgafe n'oghere na mgbawa dị na ngwa simenti.Meziwanye njikọ nke isi ihe na ngwaahịa hydration ciment, si otú a na-emeziwanye nguzogide abrasion.
6. Nye ngwa agha ahụ magburu onwe ya nguzogide alkali.
