utoto wa enamel wa acrylic
Utoto wa acrylic nthawi zambiri umafuna kugwiritsa ntchito primer yoyenera kuti zitsimikizire kuti zimamatira bwino, sizingagwe ndi dzimbiri komanso kuti zikhale zolimba.
Utoto wa acrylic ndi utoto wodziwika bwino wa topcoat womwe umauma mwachangu womwe umakhala ndi kuwala kwabwino kwambiri, utoto wosunga, kukana nyengo komanso kukongoletsa. Umagwiritsidwa ntchito kwambiri popaka utoto panja kapena m'mafakitale monga nyumba zachitsulo, zida zamakanika, magalimoto, ndi kunja kwa nyumba. Ngakhale kuti umakhala womata bwino wokha, ukagwiritsidwa ntchito mwachindunji ku zitsulo kapena konkriti, ukhoza kulephera msanga chifukwa cha kusakwanira kwa dzimbiri kapena kusagwirizana bwino.
Kuti makina onse ophikira agwire bwino ntchito, makampani nthawi zambiri amagwiritsa ntchito makina ophikira okhala ndi zigawo zambiri okhala ndi "primer + intermediate coat (ngati mukufuna) + topcoat". Ntchito ya primer ndikuwonjezera kumamatira, kupereka chitetezo cha cathodic (monga primer yokhala ndi zinc yambiri) kapena kuteteza zinthu zowononga. Ngakhale kuti enamel ya acrylic imagwira ntchito ngati topcoat, makamaka yomwe imayang'anira kukongola ndi kukana kukalamba kwa ultraviolet.
Mitundu yodziwika bwino ya ma primer
Zotsatirazi ndi ma primers omwe amagwiritsidwa ntchito kwambiri pa utoto wa acrylic ndi momwe amagwiritsidwira ntchito:
- Choyambira cha epoxy (monga epoxy zinc-rich, epoxy iron oxide)
Zinthu zazikulu: Kumatirira kwambiri, kukana dzimbiri bwino, kungapereke chitetezo cha cathodic
Zochitika zoyenera: Nyumba zachitsulo zakunja, milatho, matanki osungiramo zinthu, zombo
- Choyambira cha polyurethane
Zinthu zazikulu: Kuumitsa mwachangu, kukana nyengo, mphamvu zamphamvu zamakanika
Zochitika zogwiritsidwa ntchito: Makina omanga, magalimoto oyendera
- Choyambira cha acrylic
Zinthu zazikulu: Kuumitsa mwachangu, kugwirizana bwino ndi topcoat
Zochitika Zoyenera: Malo okhala ndi zida zofunikira kwambiri zokongoletsera
- Choyambira cha Alkyd
Zinthu zazikulu: Mtengo wotsika, zosavuta kugwiritsa ntchito
Zochitika zomwe zingagwiritsidwe ntchito: Zipangizo zamakina, nyumba zamkati
(Kufotokozera Kowonjezera)
Mafotokozedwe ena azinthu akusonyeza kuti utoto wa acrylic ungagwiritsidwe ntchito limodzi ndi epoxy primer ndi polyurethane primer; njira zofananira zimaphatikizapo "epoxy primer + epoxy zinc-rich intermediate paint + acrylic paint" kapena "S53-31 polyurethane anti-rust primer + acrylic paint".
utoto wa enamel wa acrylic
Utoto wa acrylic umalimbikitsidwa kuti ugwiritsidwe ntchito ndi primer, makamaka m'malo omwe ali ndi zinthu zowononga kwambiri (monga mlengalenga wa giredi C3 kapena kupitirira apo). Kulephera kugwiritsa ntchito primer kungayambitse:
Kumatirira kumachepa, ndipo utoto wa utoto umakhala wosavuta kuchotsedwa;
Chitsulo chachitsulo chimachita dzimbiri, zomwe zimakhudza nthawi yogwira ntchito;
Mphamvu yolimbana ndi ukalamba imafooka, ndipo kutayika kwa kuwala ndi ufa kumawonjezeka.
Ngati imagwiritsidwa ntchito poteteza pang'ono kapena kukongoletsa kwakanthawi kokha, ndipo mkhalidwe wa substrate ndi wabwino, woyera komanso wouma, ingagwiritsidwenso ntchito yokha, koma magwiridwe antchito a nthawi yayitali sangatsimikizidwe.
