Imibala yamakhoyili ensimbi enombala inothile futhi inemibalabala. Ungakhetha kanjani umbala ozifanelayo phakathi kwamakhoyili ensimbi amaningi anombala? Ukuze ugweme umehluko obalulekile wemibala, ake sibheke ndawonye.
Ukukhethwa kombala wokumboza ipuleti lensimbi yombala: Ukucatshangelwa okuyinhloko ekukhethweni kombala ukufanisa indawo ezungezile kanye nezintandokazi zomnikazi. Kodwa-ke, ngokombono wezobuchwepheshe, kunezinketho eziningi zokukhetha ama-pigments ezingubo zombala okhanyayo. Izikhala ze-Inorganic ezihlala isikhathi eside (ezifana ne-titanium dioxide) zingakhethwa, futhi amandla okubonisa okushisayo okunamathelayo aqinile (i-reflection coefficient iphindwe kabili kunaleyo yezingubo zombala omnyama). Ehlobo, izinga lokushisa lokugqoka ngokwalo liphansi, elizuzisa ekwandiseni impilo yokugqoka.
Ngaphezu kwalokho, umhleli ukhumbuza ukuthi ngisho noma ukugqoka kushintsha umbala noma i-powdery, umehluko phakathi kombala okhanyayo nombala wokuqala uncane, futhi umthelela ekubukeni awubalulekile. Imibala emnyama (ikakhulukazi imibala egqamile) inemibala eminingi ephilayo, futhi ijwayele ukufiphala lapho ichayeke emisebeni ye-ultraviolet, ishintsha umbala ezinyangeni ezintathu nje. Kumapuleti ensimbi ahlanganiswe ngombala, amazinga okushisa okunwebeka okunamathelayo kanye nepuleti lensimbi ngokuvamile ahluka, ikakhulukazi ama-coefficients wokunwebeka aqondile we-substrate yensimbi kanye ne-organic coeting ahluke kakhulu. Uma izinga lokushisa le-ambient lishintsha, isixhumi esibonakalayo phakathi kwe-substrate ne-coating izobhekana nokunwetshwa noma ingcindezi yokufinyela. Uma kungakhululwa kahle, ukuqhekeka kwe-coating kuzokwenzeka.
Ukwengeza, kufanele kuqashelwe ukuthi kunemibono emibili engalungile emakethe yamanje: enye iwukuba khona kwenani elikhulu le-primer emhlophe. Inhloso yokusebenzisa i-primer emhlophe ukunciphisa ukujiya kwejazi langaphezulu, njengoba i-primer evamile evimbela ukugqwala ukuze kwakhiwe iluhlaza ngokuphuzi (yingakho i-strontium chromate pigment) futhi kufanele ibe nogqinsi olwanele lwejazi eliphezulu. Okwesibili ukusetshenziswa kwamapuleti ensimbi afakwe umbala emisebenzini yokwakha. Iphrojekthi efanayo isebenzisa abakhiqizi abahlukene namaqoqo amapuleti ensimbi ahlanganiswe ngombala, angase abonakale anombala ofanayo phakathi nokwakhiwa. Kodwa-ke, ngemva kweminyaka eminingana yokuchayeka kokukhanya kwelanga, izitayela zokushintsha umbala wezingubo ezihlukene ezivela kubakhiqizi abahlukene zihlukile, okuholela ekuhlukeni kombala ongathi sína. Ziningi kakhulu izibonelo zalokhu. Ngisho nemikhiqizo evela kumphakeli ofanayo, kunconywa kakhulu ukuthi ufake i-oda lephrojekthi efanayo ngesikhathi esisodwa, njengoba izinombolo ze-batch ezihlukene zingasebenzisa imikhiqizo evela kubahlinzeki bepende abahlukene, okwandisa amathuba okuhluka kwemibala.
