Ufa wa latex wosungunukanso chowonjezera cha matope osakaniza ndi chowuma

Ufa wa polima wosungunuka (RDP) ndi polima womwe umagwiritsidwa ntchito ngati chowonjezera mu mortars wouma. RDP ndi ufa wopangidwa ndi kupopera mpweya wa polima. RDP ikawonjezedwa m'madzi imapanga emulsion yokhazikika yomwe ingagwiritsidwe ntchito kupanga mortars. RDP ili ndi zinthu zambiri zomwe zimapangitsa kuti ikhale chowonjezera chamtengo wapatali mu mortars wouma. Zinthu izi zikuphatikizapo:

Kusunga madzi: RDP imathandiza kusunga madzi mu matope, motero zimathandiza kuti matope azigwira ntchito bwino komanso kuchepetsa kuchuluka kwa madzi omwe amafunikira.

Kumatira: RDP ikhoza kukonza kugwirizana pakati pa matope ndi substrate, motero kukulitsa mphamvu ndi kulimba kwa matope.

Kugwira Ntchito: RDP ikhoza kukweza ubwino wa chinthu chomalizidwa mwa kupangitsa kuti matopewo azigwira ntchito mosavuta.

Kulimba: RDP imatha kulimbitsa kulimba kwa matope, zomwe zimapangitsa kuti asagwedezeke komanso asagwedezeke.

RDP ndi chowonjezera cha ntchito zambiri chomwe chingagwiritsidwe ntchito mu mortars osiyanasiyana osakaniza ouma. Ndi yoyenera makamaka mortars zomwe zimagwiritsidwa ntchito kunja monga stucco ndi matailosi. RDP ingagwiritsidwenso ntchito mu mortars zomwe zimagwiritsidwa ntchito mkati monga zodzaza majoini ndi zinthu zokonzanso.

Nazi ubwino wina wogwiritsa ntchito RDP mu dry mix mortar:

Kuthandiza kusunga madzi bwino

Sinthani kumatirira

Kupititsa patsogolo kugwira ntchito bwino

kulimba kwambiri

kuchepetsa kusweka

kuchepetsa kuwonongeka kwa madzi

onjezerani kusinthasintha

Sinthani kukana kwa nyengo

RDP ndi chowonjezera chotetezeka komanso chogwira mtima chomwe chingagwiritsidwe ntchito kukonza magwiridwe antchito a matope osakaniza ouma. Ndi chida chamtengo wapatali kwa makontrakitala ndi omanga omwe akufuna kupanga matope olimba komanso apamwamba.

Nazi zina mwa mitundu yodziwika bwino ya RDP yomwe imagwiritsidwa ntchito mu matope osakaniza ouma:

Vinyl Acetate Ethylene (VAE): VAE RDP ndi mtundu wofala kwambiri wa RDP. Ndi njira yosinthasintha komanso yotsika mtengo yomwe ingagwiritsidwe ntchito m'mabokosi osiyanasiyana.

Styrene Butadiene Acrylate (SBR): SBR RDP ndi njira yokwera mtengo kuposa VAE RDP, koma imapereka madzi abwino komanso omamatira.

Polyurethane (PU): PU RDP ndi mtundu wokwera mtengo kwambiri wa RDP, koma uli ndi madzi abwino kwambiri, umamatira bwino komanso umakhala wolimba.
