Yintoni yokwaleka ukugqiba umbala wedyasi ibhodi besmear isetyenziswa emva kwexesha, ngenxa yokuba bachatshazelwe zonke iintlobo zezinto zokusingqongileyo, impahla yayo ifilimu besmear kunye nobomi benkonzo kunokunciphisa, kufuneka ukuba kwenziwe repaint yayo.Ezona mfuno zisisiseko zokwaleka okupeyintiweyo kukuba neqondo elithile lokuncamathela kunye nokwaleka kwasekuqaleni, kunye nokuqina okungcono.Ibhodi egqunywe ngombala wangaphandle ngokuhambelana nokusetyenziswa kokusingqongileyo inokwahlulwa ibe ngamacandelo amathathu, udidi lokuqala, ukusetyenziswa kwindawo yendalo, iimfuno zempembelelo ethile yokuchasana nokubola.Njenge: indawo yokwakha, usebenzisa ibhodi egqunywe ngombala wedwa;Udidi lwe-2, olusetyenziswe kwindawo yendalo, lunokuthintela ukugqwala okuthile kunye nesiphumo sokubonakala.Njengokuba: ekwakhiweni kwangaphandle kwendlu yebhodi ehambayo;Udidi lwesithathu, olusetyenziswa kwezinye iindawo ezilukhuni, lufuna inani elithile lobomi obuchasene nokubola.
Amandla okuncamathelisa kwiipleyiti eziqatywe ngemibala eyahlukeneyo ukumisela inkqubo yokugquma iipleyiti ezinombala.I-Polyester amino umphezulu wokugquma wenkqubo iqulethe inani elikhulu le-hydroxyl kunye namaqela e-amino, kwaye ipleyiti yokwambatha yombala wokwakha ubukhulu becala iyi-semi-optical coating, i-coating iqulethe inani elikhulu lezihluzi okanye umgubo wokulinganisa, umphezulu omncinci ubonisa uburhabaxa obuthile, kulula kwaye bulungiswa. Ukugquma kwiqela le-hydrogen bonding kunye nesiphumo se-doxtail wedge, ngoko ukunamathela kunamandla.
Ngokutsho kwethiyori yokumanzisa umphezulu, ukunyanzeliswa komphezulu wengubo ekhethiweyo yokulungisa kufuneka kube ngaphantsi koxinzelelo lomphezulu wengubo yombala yokumanzisa;Iingubo zokulungisa kufuneka zibe namaqela e-polar angenza iibhondi ze-hydrogen;Ipeyinti yokulungisa ukuze iqulethe i-solvent enamandla ingaba yipeyinti yokudumba, ukwenzela ukuba kuphuculwe ukunamathela phakathi kweemaleko;Kwangaxeshanye, ukutyabeka kungasetyenziselwa ukuthoba ubunzima bemolekyuli yeresin okanye ukunciphisa i-viscosity yotyatyazo, ukusetyenziswa kwe-solvent ecothayo eguquguqukayo kunye nesantya esisezantsi sokunxibelelanisa i-coat ukuphucula ukunamathela kwayo kwi-coating yombala. ipleyiti.
