Indlela yokuhlola yezakhiwo kanye ne-viscosity ye-polymer powder ehlakazeka kabusha ye-RDP, Emhlabeni wonke isetshenziswa kabanzi ukusabalalisa i-polymer powder RDP nge-vinyl acetate kanye ne-ethylene copolymerized emulsion powder, i-ethylene kanye ne-vinyl chloride kanye ne-lauric acid vinyl ester ternary copolymer powder, i-vinyl acetate kanye ne-ethylene kanye ne-senior fatty acid vinyl ester ternary copolymer powder, lezi ezintathu ukusabalalisa i-polymer powder RDP emakethe yonke evelele, ikakhulukazi i-vinyl acetate kanye ne-ethylene copolymer powder VAC/E, Ithatha isikhundla esiphambili emkhakheni womhlaba wonke futhi imelela izici zobuchwepheshe ze-polymer powder ehlakazeka kabusha ye-RDP.
Impuphu ye-polymer ephinde ihlakazekeI-RDP inamandla amakhulu okubopha, ithuthukisa ukuguquguquka kwe-mortar futhi inesikhathi eside sokuvula, inikeza i-mortar ukumelana okuhle kakhulu kwe-alkaline, ithuthukisa ukunamathela kwe-mortar, amandla okugoba, ukungangeni manzi, i-plasticity, ukumelana nokuguguleka kanye nokwakhiwa, ku-mortar eguquguqukayo yokulwa nokuqhekeka inokuguquguquka okunamandla.
Kusukela kokuhlangenwe nakho kobuchwepheshe be-polymer eguqulwe yi-mortar, kuseyisisombululo sobuchwepheshe esingcono:
1, i-RDP ingenye yama-polymer asetshenziswa kakhulu emhlabeni.
2, Ulwazi olubanzi lokusebenzisa emkhakheni wezakhiwo;
3, ingahlangabezana nezidingo zezakhiwo ze-rheological ze-mortar (okungukuthi, ukwakhiwa okudingekayo);
4, kanye nezinye i-monomer polymer resin ine-organic volatile matter ephansi (i-VOC) kanye nezici zegesi ezicasulayo eziphansi;
5, enokumelana okuhle kakhulu kwe-UV kanye nokumelana okuhle nokushisa kanye nokuqina kwesikhathi eside;
6, enokumelana okuphezulu kwe-saponification;
7, enezinga lokushisa elibanzi lengilazi (Tg);
8, enokubopha okuphelele okuhle kakhulu, ukuguquguquka kanye nezakhiwo zemishini;
9, ukusebenza okulula nokufanayo kwenhlanganisela ye-colloid evikelayo (i-polyvinyl alcohol).
Indlela yokuthola amandla okunamathela e-RDP ye-polymer ephinde ihlakazeke ibonakala ngezindlela ezilandelayo zokunquma:
1, qala ngokuthatha i-polymer powder ephinde ihlakazeke i-RDP 5g uyifake enkomishini yokulinganisa yengilazi, engeza amanzi ahlanzekile ayi-10g bese uvuselela imizuzu emi-2, uyixube ngokulinganayo;
2. Beka indebe yokulinganisa exubile imizuzu emi-3 bese uvuselela futhi imizuzu emi-2;
3. Gcoba lonke ikhambi endebeni yokulinganisa epuletini lengilazi elihlanzekile elivundlile;
4, faka ipuleti lengilazi ebhokisini lokuhlola lokulingisa indawo enezinga lokushisa eliphansi le-DW100;
5, ekugcineni ibekwe ezimweni zokulingisa zemvelo ezingama-0°C ihora eli-1, khipha ipuleti lengilazi, uvivinye izinga lokwakheka kwefilimu, ngokuya ngesilinganiso sokuguqulwa kwesilinganiso sokwakheka kwefilimu se-polymer powder ephinde ihlakazeke i-RDP ngokusebenzisa amandla ajwayelekile okubopha.
