4. Ngwa nke RDP na ịkwalite nguzogide sag
A na-eji RDP eme ihe n'ọtụtụ ebe na ihe owuwu iji kwalite nguzogide sag:
a. Tile Adhesives: RDP na-eme ka adhesion na sag na-eguzogide nke tile adhesives, na-eme ka njikọ dị mma na ibelata nkwụsị tile n'oge echichi.
b. Rendering na Stucco: Na plasta mpụga na stucco, RDP na-abawanye nguzogide sag ma na-enye ohere maka ire ụtọ, ọbụlagodi ngwa n'elu kwụ ọtọ na-enweghị mbelata ma ọ bụ nrụrụ.
C. Ogige ndị na-edozi onwe: Enwere ike itinye RDP n'ime ogige ndị na-eme ka ọ dịkwuo mma iji meziwanye mmiri na nkwụsị nke sag, na-eme ka elu ala dị larịị na larịị.
d. Igwe anaghị agba nchara: RDP na-eme ka nguzogide sag nke akpụkpọ ahụ na-ekpuchi mmiri, na-ahụ na ọbụna mkpuchi ma na-enye nchebe nchebe a pụrụ ịdabere na ya.
5. Okwu ikpe na ihe atụ
Ọtụtụ ọmụmụ ihe na ihe atụ na-egosi ịdị irè nke RDP n'ịkwalite nguzogide sag:
a. Ọmụmụ ihe 1: Ngwa nke RDP na nrapado tile maka nnukwu ọrụ azụmahịa, na-egosipụta nkwụsi ike sag na ogologo oge.
b. Ọmụmụ ikpe 2: Ntụle nke RDP gbanwetụrụ na facades na-egosipụta nguzogide sag dị elu na nguzogide ihu igwe.
C. Ọmụmaatụ 1: Ntụle nke sag nguzogide nke ngwa agha na enweghị mgbakwunye RDP, na-akọwapụta mmụba dị ịrịba ama enwetara na RDP.
d. Ọmụmaatụ 2: Nnwale ubi nke RDP emezigharịrị nhazi ọkwa onwe ya, na-egosi ịdị mfe ojiji yana nguzogide sag mara mma n'okpuru ọnọdụ ụwa n'ezie.
Redispersible polymer powders (RDP) na-arụ ọrụ dị mkpa n'ịkwalite nguzogide sag nke ihe owuwu ụlọ, na-enye nchikota nke ihe nrụnye igwe, imepụta ihe nkiri na njide mmiri. Site n'ịghọta usoro na ihe ndị na-emetụta nguzogide sag na iji ụzọ nyocha kwesịrị ekwesị, ndị injinia na ndị ọrụ ngo nwere ike iji RDP rụọ ọrụ nke ọma iji nweta ngwọta ụlọ na-adịgide adịgide na nke dị elu. Site na nyocha na ihe ọhụrụ na-aga n'ihu, a na-atụ anya na RDP ga-anọgide na-abụ ihe mgbakwunye dị mkpa n'ịdozi ihe ịma aka ndị metụtara mgbagha na ịkwalite ubi ihe owuwu ụlọ.
