Uvavanya njani i-polymer powder RDP?

Indlela yokuvavanya iipropathi kunye ne-viscosity ye-polymer powder RDP, kwihlabathi jikelele isetyenziselwa ukusasaza i-polymer powder RDP kunye ne-vinyl acetate kunye ne-ethylene copolymerized emulsion powder, i-ethylene kunye ne-vinyl chloride kunye ne-lauric acid vinyl ester ternary copolymer powder, i-vinyl acetate kunye ne-ethylene ephezulu i-acid vinyl ester ternary copolymer powder, ezi zintathu zokusasaza i-polymer powder RDP kwimarike yonke elawulayo, ngakumbi i-vinyl acetate kunye ne-ethylene copolymer powder VAC / E, Ithatha indawo ehamba phambili kwintsimi yehlabathi kwaye imele iimpawu zobugcisa ze-polymer powder RDP.

I-polymer powder enokuchithwa kwakhonaI-RDP inamandla abalaseleyo ebhondi, iphucula ukuguquguquka kodaka kwaye inexesha elide lokuvula, inika udaka olugqwesileyo ukumelana ne-alkali, ukuphucula ukunamathela kodaka, amandla okuguquguquka, ukungangeni kwamanzi, iplastiki, ukuxhathisa kunye nokwakhiwa, kwi-flexible anti-crack mortar. unokuguquguquka okunamandla.

Ukusuka kumava obugcisa bepolymer eguqulwe ngodaka, isesisisombululo esingcono sobugcisa:

1, iRDP yenye yezona polymer zisetyenziswa kakhulu kwihlabathi.
I-2, amava abanzi esicelo kwinkalo yezokwakha;

I-3, inokuhlangabezana neemfuno zeempawu ze-rheological zodaka (oko kukuthi, ukwakhiwa okufunekayo);

I-4, kunye nenye i-resin ye-polymer ye-monomer inomcimbi ophantsi we-organic volatile (VOC) kunye neempawu zegesi ezinomsindo ophantsi;

I-5, ngokuxhathisa okugqwesileyo kwe-uv kunye nokumelana nobushushu obuhle kunye nokuzinza kwexesha elide;

I-6, enokumelana okuphezulu kwe-saponification;

7, kunye noluhlu olubanzi lweglasi lobushushu (Tg);

8, kunye nokudibanisa okugqwesileyo okugqibeleleyo, ukuguquguquka kunye neempawu zoomatshini;

I-9, ilula kunye nokusebenza okufanayo kwe-colloid yokukhusela (i-polyvinyl alcohol) indibaniselwano.

Indlela yokufumanisa amandla okunamathela kwi-polymer powder RDP ibonakaliswe ngolu hlobo lulandelayo:

I-1, thatha kuqala i-polymer powder e-dispersible RDP 5g kwiglasi yokulinganisa indebe, yongeza i-10g yamanzi acocekileyo kwaye ugxobhoze i-2min, yenza ukuba ixutywe ngokulinganayo;

2. Beka indebe yokulinganisa edibeneyo ye-3min kwaye uvuselele kwakhona i-2min;

3. Thambisa sonke isisombululo kwikomityi yokumejarisha kwipleyiti yeglasi ethe tyaba ecocekileyo;

4, faka ipleyiti yeglasi kwi-DW100 kwibhokisi yovavanyo lokulinganisa lobushushu obuphantsi;

I-5, ekugqibeleni ifakwe kwi-0 ° C yeemeko zokulinganisa okusingqongileyo kwi-1 iyure, thatha isitya seglasi, uvavanye izinga lokubunjwa kwefilimu, ngokwezinga lokuguqulwa kwefilimu yokuguqulwa kwe-polymer powder RDP ekusebenziseni amandla aqhelekileyo okudibanisa.
