Polymer powder (RDP) na-agbanwe agbanwebụ otu n'ime ihe mgbakwunye dị mkpa ma dị mkpa na sistemu ngwa agha agwakọtara akpọnwụ nke oge a, ọkachasị na nrapado tile. Ọ bụ polymer organic na-atọghata emulsion n'ime ntụ ntụ site a ịgba ihicha usoro. Ọ nwere ezi redispersibility na ike regharịa-etolite a kwụsiri ike emulsion mgbe agwakọta na mmiri, si otú na-enye ngwa agha magburu onwe bonding Njirimara, mgbanwe na-ewu arụmọrụ.
1. Usoro ọrụ nke RDP na nrapado tile
Tile nrapado bụ a akọrọ-agwakọta ngwa agha ngwaahịa na-eji nkekọ taịl nile n'elu nke isi, tumadi esịnede simenti, ezi mkpokọta, thickener, polymer nwekwara, wdg N'etiti ha, RDP, dị ka a polymer modifier, nwere ike budata melite keukwu arụmọrụ nke tile nrapado. Usoro ọrụ ya bụ nke a:
1.1. Ike njikọta emelitere
Ihe nkiri polymer nke RDP guzobere mgbe hydration gachara nwere ike banye n'ime microporous Ọdịdị nke isi iji mepụta aru aru, na mekọrịta ngwaahịa ciment hydration ngwaahịa iji kwalite ike njikọ n'etiti nrapado taịlị na taịlị na ala ala.
2.1. Melite mgbanwe
Ihe nkiri polymer nwere mgbanwe dị mma ma nwee ike ịmịnye nrụgide nke ọma site na mgbasawanye okpomọkụ na nkwụsịtụ ma ọ bụ obere ngbanwe nke oyi akwa isi iji gbochie taịl nile ka ọ ghara ịgbawa ma ọ bụ daa.
2.3. Melite arụmọrụ ihe owuwu
RDP na-agbatị oge ọrụ nke nrapado tile, na-eme ka mmanu na-ahụ maka ihe owuwu, ma na-emeziwanye arụmọrụ ihe owuwu.
2.4. Melite nguzogide mgbawa na enweghị ike
Ihe nkiri polymer nwere ike mejupụta pores capillary na ngwa ngwa ciment, belata porosity, ma melite nkwụsị mgbawa na enweghị ike.
2.5. Mee ka ịdịte aka na mmiri na-eguzogide
RDP na-akwalite nguzogide nke usoro ngwa agha na gburugburu mpụga (dịka iru mmiri, oke okpomọkụ, friza-thaw, wdg) ma na-agbatị ndụ ọrụ nke nrapado tile.
2. Uru arụmọrụ nke RDP
Ojiji nke RDP na nhazi nke nrapado tile nwere uru ndị a dị ịrịba ama:
Ike njikọta dị elu: na-eme ka ike njikọta nke tile nrapado na taịlị (gụnyere taịlị vitrified, taịlị a na-egbu maramara, wdg), na-adaba n'ụdị elu dị iche iche.
Kwado na gburugburu ebe dị iche iche: RDP na-enye nrapado tile nke ọma mmiri na-eguzogide mmiri, nkwụsi ike na-ekpo ọkụ, na ịka nká, ma dabara maka ebe dị iche iche nke ime ụlọ na n'èzí.
Mgbanwe siri ike: Kwesịrị ekwesị maka ọnọdụ dị elu achọrọ dị ka ihe owuwu nke obere oyi akwa, taịlị ndị buru ibu, na taịlị na mgbidi.
Enyi na gburugburu ebe obibi na nchekwa: RDP bụ ihe na-adịghị egbu egbu na enweghị isi nke na-emezu ihe nchekwa gburugburu ebe obibi nke ihe ụlọ akwụkwọ ndụ akwụkwọ ndụ.
3. akwadoro usoro onunu ogwu na ntụnyere usoro
Ekwesịrị ikpebi ọnụọgụ RDP akwadoro dabere na ọkwa arụmọrụ, ọnọdụ ngwa na usoro usoro nke nrapado taịlị. N'ozuzu oke bụ dị ka ndị a:
Nkịta taịlị nkịtị (ụdị C1): Ọnụ ego mgbakwunye akwadoro bụ 1.5% ~ 3% nke mkpokọta arọ nke ntụ ntụ gluu.
Nnyapade tile na-arụ ọrụ dị elu (ụdị C2): Ego mgbakwunye akwadoro bụ 3% ~ 6%, ma ọ bụ ọbụna karịa.
Mgbakwunye taịlị na-agbanwe agbanwe (ụdị S1/S2): Ego mgbakwunye nwere ike ịdị elu dị ka 6% ~ 10% iji kwalite mgbanwe na ikike mbupụ.
Usoro ntụaka (ihe atụ nke nrapado tile ọkwa C2):
Simenti Portland nkịtị: 40%
Aja quartz (0.1-0.3mm): 50%
RDP: 4%
HPMC: 0.3%
Ihe mgbochi mgbochi: 0.1%
Defoamer: ego kwesịrị ekwesị
Ihe mgbakwunye mmiri / ihe mgbakwunye ndị ọzọ: ndozi dị mma dịka mkpa siri dị
4. Na ọdabara tile ụdị na mkpụrụ ọnọdụ
Ihe nrapado taịlị emeziri na RDP dabara adaba maka ụdị taịlị na ihe dị iche iche, gụnyere mana ọnweghị oke na:
Ụdị taịlị: taịlị glazed, taịlị a na-egbu maramara, taịlị vitified, mosaics, marble, nkume wuru ewu, wdg.
Ụdị mkpụrụ: isi mmiri ciment, bọọdụ ciment, bọọdụ gypsum, ntọala tile ochie, bọọdụ kọmpụta, wdg.
Ihe nrapado tile emezigharịrị na RDP dabara adaba maka ịkwanye taịlị mmiri dị ala na taịlị buru ibu, nke nwere ike dozie nsogbu nke enweghị ike njikọta nke ngwa simenti ọdịnala.
5. Akpachara anya
N'oge mmepụta na ntinye akwụkwọ n'ezie, isi ihe ndị a kwesịrị iburu n'uche:
Họrọ ụdị RDP kwesịrị ekwesị (dị ka ethylene-vinyl acetate copolymer EVA, acrylic polymer, wdg) iji mezuo ihe dị iche iche chọrọ ịrụ ọrụ.
Debe nkụ n'oge nchekwa iji zere mmiri na agglomeration.
Ejila ihe alkaline dị elu chekwaa ogologo oge iji gbochie arụmọrụ ka ọ ghara imetụta.
Gwakọta nke ọma ka ịzenarị nkesa ntụ ntụ na-edoghị anya na-eduga n'ịrụ ọrụ na-akwụghị ụgwọ.
Dị ka isi ihe na-arụ ọrụ na tile adhesives, polymer powders redispersible na-emeziwanye ike nkekọ, mgbanwe na ịdịte aka nke adhesives tile, na-egbo mkpa nke ụlọ ọgbara ọhụrụ maka ihe na-arụ ọrụ tile paving. N'ọdịnihu, na mmepe nke ụlọ mmepụta ihe, nangwa nke RDP na tile adhesives na ọtụtụ ngwa ngwa agwakọtara akọrọga-abawanye ụba, na arụmọrụ ya na uru gburugburu ebe obibi ga-anọgide na-akwalite ụlọ ọrụ ihe owuwu ụlọ na ọkwa dị elu.
