Uthelekiso phakathi kweengubo ze-UV kunye nezinye izinto zokuhombisa Nangona unyango lwe-UV lusetyenzisiwe kurhwebo iminyaka engaphezu kwamashumi amathathu (yeyona ndlela iqhelekileyo yokugquma i-compact disk screen printing kunye ne-lacquering ngokomzekelo), iingubo ze-UV zisentsha kwaye zikhula. Ulwelo lwe-UV lusetyenziswa kwiikesi zeeselfowuni zeplastiki, iiPDA kunye nezinye izixhobo zombane eziphathwa ngesandla. Iingubo zomgubo ze-UV zisetyenziswa kumacandelo efanitshala ye-fiberboard exineneyo. Ngelixa kukho ukufana okuninzi nezinye iintlobo zeengubo,Funda ngokugqithisileyo …

I-UV-enyangekayo yePowder Coatings Advantages UV-curable powder coatings yenye yezona khemistri zokugquma ezikhawulezayo ezikhoyo. Ukususela ekuqaleni ukuya ekugqibeleni yonke inkqubo yokugqiba i-MDF ithatha i-20 min okanye ngaphantsi, kuxhomekeke kwi-chemistry kunye nenxalenye yejometri, okwenza kube yinto efanelekileyo yokugqiba izicelo ezifuna ukuguqulwa ngokukhawuleza. Inxalenye egqityiweyo idinga ingubo enye kuphela, ivumela imveliso eyongeziweyo kunye ne-40 ukuya kwi-60 ipesenti yamandla angaphantsi kunezinye iinkqubo zokugqiba. Inkqubo yokunyanga i-UV ilula kakhulu kunezinye iiteknoloji zokugqiba. UkunyangaFunda ngokugqithisileyo …

Iingubo zomgubo ze-UV zizisa izibonelelo zokufudumeza ii-substrates ezinobuthathaka Ukwaleka kwePowder kubonelela ngokuhlala ixesha elide, okunomtsalane kunye neyoqoqosho enye indlela kwiipeyinti ezingamanzi kunye nelaminates kuluhlu olubanzi lweemveliso ezingevani nobushushu njengeglasi kunye nezixhobo zeplastiki. Iingubo zomgubo zomile, iipeyinti ze-100 zeepesenti eziqinileyo ezifafazwa ngenkqubo efana nepeyinti yolwelo. Xa sele zigqunyiwe, iimveliso zihanjiswa nge-oveni ephilisayo, apho umgubo unyibilika ukuze wenze isiphelo esomeleleyo nesinomtsalane. Iingubo zomgubo ziye zahlala ixesha elideFunda ngokugqithisileyo …

Ziyintoni iiNzuzo ze-UV yePowder Coating kwiTekhnoloji ye-UV ye-UV yokugqoka i-UV inika indlela ekhawulezayo, ecocekileyo neyoqoqosho enomtsalane ukufezekisa ukugqitywa komgangatho ophezulu kwii-substrates ezisekwe ngamaplanga. Inkqubo yokwaleka inala manyathelo alandelayo: Okokuqala inqaku liyaxhonywa okanye libekwe kwibhanti lokuhambisa kwaye umgubo utshizwe ngombane kwinto leyo. Emva koko into edibeneyo ingena kwi-oven (ukushisa kwe-90-140 degC yanele) apho i-powder iyancibilika kwaye igeleza ndawonye ukuze yenze ifilimu.Funda ngokugqithisileyo …

Idibaniso ye-methacrylated polyester kunye ne-acrylated epoxy resin inika umxube onomdla weepropati kwifilimu ephilisiwe. Ubukho be-polyester backbone kubangela ukuchasana kakuhle kweengubo kwiimvavanyo zemozulu. I-epoxy backbone inika ukuchasana kweekhemikhali okubalaseleyo, ukunamathela okuphuculweyo kunye nokugudiswa. Inxalenye yemarike enomtsalane kwezi zogqumethelo ze-UV zomgubo zithatha indawo yePVC laminates kwiiphaneli zeMDF kushishino lwefenitshala.
