Ungahlola kanjani i-polymer powder RDP ehlakazekayo?

Indlela yokuhlola yezakhiwo kanye ne-viscosity ye-redispersible polymer powder RDP, Emhlabeni jikelele isetshenziswa kabanzi ukuhlakaza i-polymer powder RDP nge-vinyl acetate ne-ethylene copolymerized emulsion powder, i-ethylene ne-vinyl chloride ne-lauric acid vinyl ester ternary copolymer powder, i-vinyllene acetate kanye ne-ethylene ephezulu i-acid vinyl ester ternary copolymer powder, lezi zintathu zokusabalalisa i-polymer powder RDP kuyo yonke imakethe ehamba phambili, ikakhulukazi i-vinyl acetate ne-ethylene copolymer powder VAC/E, Ithatha isikhundla esiphambili emkhakheni womhlaba wonke futhi imele izici zobuchwepheshe ze-polymer powder RDP ehlakazeka kabusha. .

I-polymer powder ehlakazeka kabushaI-RDP inamandla ebhondi avelele, ithuthukisa ukuguquguquka kodaka futhi inesikhathi eside sokuvula, inikeze udaka ukumelana okuhle kakhulu kwe-alkali, ithuthukise ukunamathela kokunamathela kodaka, amandla aguquguqukayo, okungangeni manzi, ipulasitiki, ukumelana nokugqoka kanye nokwakhiwa, odakeni oluguquguqukayo lwe-anti-crack. inokuguquguquka okunamandla.

Kusukela kokuhlangenwe nakho kwezobuchwepheshe kwe-polymer elungiswe ngodaka, kuseyisixazululo esingcono sobuchwepheshe:

1, i-RDP ingenye yama-polymer asetshenziswa kakhulu emhlabeni.
2, Isipiliyoni esibanzi sohlelo lokusebenza emkhakheni wezokwakha;

I-3, ingahlangabezana nezidingo zezakhiwo ze-rheological zodaka (okungukuthi, ukwakhiwa okudingekayo);

4, enenye i-monomer polymer resin ine-organic volatile matter (VOC) ephansi nezici zegesi ezicasulayo;

5, enokumelana okuhle kakhulu kwe-uv nokumelana nokushisa okuhle nokuzinza kwesikhathi eside;

6, nge high saponification ukumelana;

7, enezinga lokushisa elibanzi lengilazi (Tg);

8, enesibopho esihle kakhulu sokuhlanganisa, ukuguquguquka kanye nezakhiwo zemishini;

9, ukusebenza okulula nokufanayo kwenhlanganisela yokuvikela i-colloid (i-polyvinyl alcohol).

Indlela yokuthola yamandla okunamathela we-polymer powder RDP ehlakazeka kabusha ibonakala ngezindlela zokunquma ezilandelayo:

1, qala ngokuthatha kabusha i-polymer powder RDP 5g enkomishini yokulinganisa ingilazi, engeza u-10g wamanzi ahlanzekile bese ugoqa imizuzu emi-2, uwenze uxutshwe ngokulinganayo;

2. Beka inkomishi yokulinganisa exubile imizuzu emi-3 bese ugoqoza futhi imizuzu emi-2;

3. Gcoba lonke ikhambi enkomishini yokulinganisa epuleti lengilazi elivundlile elihlanzekile;

4, faka ipuleti yengilazi ebhokisini lokuhlola le-DW100 lokushisa eliphansi lendawo yokulinganisa;

I-5, ekugcineni ifakwe ku-0 ° C izimo zokulingisa kwemvelo ngehora elingu-1, khipha ipuleti yengilazi, uhlole izinga lokubunjwa kwefilimu, ngokusho kwesilinganiso sokwakheka kwefilimu ukuguqulwa kwe-polymer powder RDP esetshenziswa kabusha ekusebenziseni amandla ajwayelekile okubopha.
