Imibala yeekhoyili zetsimbi ezinombala zizityebi kwaye zinemibala. Indlela yokukhetha umbala ohambelanayo phakathi kwemibala emininzi yeekhoyili zensimbi? Ukunqanda ukungafani kwemibala ebalulekileyo, makhe sijonge kunye.
Ukukhethwa kombala wengubo yeplate yentsimbi yombala: Ingqwalasela ephambili yokukhethwa kombala kukuhambelana nokusingqongileyo kunye nezinto ezikhethwa ngumnini. Nangona kunjalo, kumbono wobugcisa, kukho uluhlu olubanzi lokukhetha ii-pigments kwiingubo zombala okhanyayo. Ii-pigments ze-Inorganic kunye nokuqina okuphezulu (ezifana ne-titanium dioxide) zinokukhethwa, kwaye amandla okubonisa i-thermal ye-coefficient yomelela (i-reflection coefficient iphindwe kabini kunombala omnyama). Ehlotyeni, iqondo lokushisa kwengubo ngokwayo liphantsi, eliluncedo ekwandiseni ubomi bokugquma.
Ukongezelela, umhleli ukhumbuza ukuba nangona isambatho sitshintsha umbala okanye i-powdery, umehluko phakathi kombala okhanyayo kunye nombala wokuqala uncinci, kwaye impembelelo kwimbonakalo ayibalulekanga. Imibala emnyama (ingakumbi imibala eqaqambileyo) ubukhulu becala i-organic ngombala, kwaye ithande ukubuna xa ibekwe kwimitha yeultraviolet, itshintsha umbala kwiinyanga nje ezintathu. Kwiipleyiti zentsimbi ezigqunywe ngombala, izinga lokwandiswa kwe-thermal yokwaleka kunye nepleyiti yentsimbi idla ngokuhluka, ngakumbi i-coefficients yokwandiswa komgca we-metal substrate kunye ne-organic coeating yahluke kakhulu. Xa ubushushu be-ambient buguquka, i-interface phakathi kwe-substrate kunye ne-coating iya kuba nokwandiswa okanye ukunyanzeliswa kwengcinezelo. Ukuba ayikhutshwanga ngokufanelekileyo, ukuqhekeka kwe-coating kuya kwenzeka.
Ukongezelela, kufuneka kuqatshelwe ukuba kukho izinto ezimbini eziphosakeleyo kwiimarike zangoku: enye kubukho bexabiso elikhulu le-primer emhlophe. Iinjongo zokusebenzisa i-primer emhlophe kukunciphisa ubukhulu be-topcoat, njengoko i-primer yesiqhelo enganyangekiyo yokwakhiwa iluhlaza okwesibhakabhaka (kungoko i-strontium chromate pigment) kwaye kufuneka ibe nobukhulu obaneleyo be-topcoat. Okwesibini kukusetyenziswa kwamacwecwe ensimbi afakwe umbala kwiiprojekthi zokwakha. Iprojekthi efanayo isebenzisa abavelisi abahlukeneyo kunye neebhetshi zeepleyiti zensimbi ezifakwe umbala, ezinokubonakala zinombala ofanayo ngexesha lokwakha. Nangona kunjalo, emva kweminyaka eliqela yokuvezwa kokukhanya kwelanga, iindlela zokutshintsha umbala kwiingubo ezahlukeneyo ezivela kubavelisi abahlukeneyo ziyahluka, nto leyo ekhokelela kumahluko amakhulu wemibala. Mininzi kakhulu imizekelo yoku. Nakwiimveliso ezivela kumthengisi ofanayo, kucetyiswa ngamandla ukuba ubeke iodolo yeprojekthi efanayo ngexesha elinye, njengoko amanani ebhetshi ahlukeneyo anokusebenzisa iimveliso ezivela kubaboneleli bepeyinti abahlukeneyo, ukwandisa amathuba okuba nokwahluka kombala.
