Injongo yophononongo olutsha yayikukuhlalutya impembelelo yokwakheka kwe-basecoat kunye nobukhulu kwindlela yokuziphatha koomatshini benkqubo yokugqiba amaplanga alekwe kaninzi enyangekayo yi-UV.
Ukuqina kunye neempawu zobuhle bomgangatho wokhuni zivela kwiipropati zengubo esetyenziswe kwindawo yayo. Ngenxa yesantya esikhawulezayo sokunyanga, ukuxinana okuphezulu kokuhlangana kunye nokuqina okuphezulu, iingubo ezinyangekayo ze-UV zihlala zikhethwa kwiindawo ezisicaba ezinjengomgangatho owenziwe ngamaplanga, iitafile kunye neengcango. Kwimeko yomgangatho womthi oqinileyo, iintlobo ezininzi zokuwohloka kwindawo yokwaleka zinokuphazamisa imbono yemveliso yonke. Kulo msebenzi wangoku, i-UV-curable formulations kunye nezibini ezahlukeneyo ze-monomer-oligomer zalungiswa kwaye zisetyenziswa njenge-basecoat ngaphakathi kwenkqubo yokugqiba iinkuni ezininzi. Ngelixa i-topcoat yenzelwe ukunyamezela uninzi lwemithwalo esetyenziswayo, i-elastic kunye noxinzelelo lweplastiki inokufikelela kumaleko anzulu.
Ngexesha lophononongo, iipropathi ezibonakalayo ezinjengomndilili wecandelo lethiyori ubude, iqondo lokushisa lokutshintsha kweglasi kunye nokuxinana kwe-crosslinking, iifilimu ezizimeleyo zezibini ezahlukeneyo ze-monomer-oligomer zaphandwa. Emva koko, uvavanyo lokungena kunye nokumelana nokukrweleka lwenziwa ukuze kuqondwe indima ye-basecoat kwimpendulo yomatshini yotyatyazo olunamanqanaba amaninzi. Ubunzima be-basecoat esetyenzisiweyo bufunyenwe bunempembelelo enkulu ekuchaseni komatshini wenkqubo yokugqiba. Akukho lunxulumano luthe ngqo lusekiweyo phakathi kwe-basecoat njengeefilimu ezizimeleyo kunye nangaphakathi kotyatyazo olunamanqanaba amaninzi, kuthathelwa ingqalelo ukuntsokotha kwezi nkqubo iindlela zokuziphatha ezininzi zabhaqwa. Isixokelelwano sokugqiba esikwaziyo ukukhuthaza ukuxhathisa kokukrweleka kokukrweleka kunye nemodyuli elungileyo yokuhlenga yafunyanwa ukulungiselela ulwakhiwo olubonisa ulungelelwaniso phakathi koxinano lwenethiwekhi kunye nokunwebeka.
