The best package is rarely the cheapest single grade.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>La tecnologia di verniciatura UV \u00e8 diventata il pilastro dei rivestimenti ecologici grazie al suo rispetto dell'ambiente, all'alta efficienza e all'elevata durezza, ed \u00e8 inevitabilmente e sempre pi\u00f9 accettata in un'ampia gamma di applicazioni. La gamma di substrati su cui pu\u00f2 essere applicata si \u00e8 evoluta dal legno e dalla carta alla plastica, ai metalli, alla ceramica, al vetro e ad altri settori.<\/p>\n<p>&nbsp;<\/p>\n<p>Principio e caratteristiche della polimerizzazione UV<\/p>\n<p>La polimerizzazione UV (UV curing) si riferisce alla forte irradiazione di luce ultravioletta, il sistema di sostanze fotosensibili nella reazione chimica per produrre frammenti attivi, innescando il sistema di monomeri attivi o polimerizzazione zwitterionica, reticolazione, in modo che il sistema dal rivestimento liquido istantaneamente in un rivestimento solido. Il processo di polimerizzazione \u00e8 un processo di reazione fotochimica, ovvero, sotto l'azione dell'energia della luce ultravioletta, il prepolimero in un periodo di tempo molto breve si polimerizza in un film, la luce UV oltre a causare la polimerizzazione superficiale del materiale, penetra maggiormente nell'inchiostro liquido polimerizzabile con i raggi UV e stimola l'ulteriore polimerizzazione dell'inchiostro profondo; rispetto all'inchiostro tradizionale, la polimerizzazione dell'inchiostro polimerizzabile con i raggi UV e l'essiccazione sono pi\u00f9 complete, senza alcuna evaporazione o contaminanti a base di solventi, 100% polimerizzazione. La tecnologia di polimerizzazione UV si \u00e8 sviluppata rapidamente in tutto il mondo e si sta diffondendo rapidamente nei settori dell'elettronica, della stampa, dell'edilizia, della decorazione, della medicina, dei macchinari, della chimica e dell'industria automobilistica.<\/p>\n<p>&nbsp;<\/p>\n<p>La tecnologia di polimerizzazione UV \u00e8 ampiamente utilizzata soprattutto per i suoi vantaggi unici: polimerizza rapidamente, soddisfacendo le esigenze della moderna produzione automatizzata; \u00e8 priva di inquinamento, in linea con la direzione di sviluppo dei moderni rivestimenti e inchiostri; il film di rivestimento di alta qualit\u00e0, l'elevata durezza, la resistenza ai graffi, la resistenza alla corrosione e altri vantaggi hanno attirato molta attenzione.<\/p>\n<p>&nbsp;<\/p>\n<p>Qui di seguito vengono illustrati i sei fattori che influenzano l'incompleta polimerizzazione a luce UV<\/p>\n<p>&nbsp;<\/p>\n<p>1, l'energia della luce ultravioletta.<\/p>\n<p>(1). L'energia della luce UV \u00e8 insufficiente, in genere perch\u00e9 la densit\u00e0 di potenza di produzione della lampada uv \u00e8 troppo piccola o i parametri del trasformatore non corrispondono, causando cos\u00ec una polimerizzazione incompleta.<\/p>\n<p>(2). I rivestimenti UV nel fotoiniziatore non sono sufficienti ad assorbire un'energia UV ragionevole, con conseguente polimerizzazione incompleta.<\/p>\n<p>&nbsp;<\/p>\n<p>2. La temperatura all'interno del forno UV \u00e8 troppo bassa.<\/p>\n<p>A causa dell'eccessivo volume d'aria della ventola centrifuga o dell'eccessivo raffreddamento ad acqua, la situazione di blocco dell'ossigeno \u00e8 troppo forte e la temperatura superficiale della lampada UV \u00e8 troppo bassa per funzionare correttamente, con conseguente polimerizzazione incompleta delle vernici UV.<\/p>\n<p>&nbsp;<\/p>\n<p>3, la distanza della lampada fotopolimerizzante.<\/p>\n<p>La lampada UV e il riflettore e la distanza tra la superficie dell'oggetto illuminato in 7 ~ 8 cm quando l'energia UV pi\u00f9 forte, ma in base ai diversi substrati di polimerizzazione, la distanza di polimerizzazione generale \u00e8 selezionata a circa 10 ~ 15 cm.<\/p>\n<p>(1). Se la distanza \u00e8 troppo bassa, la temperatura superficiale della lampada UV \u00e8 molto elevata e il substrato si deforma a causa del calore.<\/p>\n<p>(2). La distanza \u00e8 troppo elevata, l'energia UV \u00e8 ridotta, la superficie del substrato non \u00e8 asciutta e appiccicosa.<\/p>\n<p>&nbsp;<\/p>\n<p>4, lo spessore del rivestimento UV.<\/p>\n<p>Lo spessore del rivestimento UV gioca un ruolo fondamentale nell'effetto della polimerizzazione UV, in base alla tonalit\u00e0 della vernice, alla temperatura, alla velocit\u00e0 di polimerizzazione, alla superficie del substrato e ad altre condizioni diverse per un impiego appropriato.<\/p>\n<p>(1). Il rivestimento \u00e8 troppo spesso, il tempo di essiccazione \u00e8 relativamente lungo sotto l'irradiazione della stessa fonte di luce, da un lato, influisce sull'essiccazione profonda del rivestimento UV, dall'altro, rende la temperatura superficiale del substrato troppo alta, portando alla deformazione del substrato.<\/p>\n<p>(2). Lo strato di rivestimento \u00e8 troppo sottile, il che comporta una scarsa lucentezza superficiale del prodotto e l'impossibilit\u00e0 di ottenere l'effetto superficiale desiderato.<\/p>\n<p>&nbsp;<\/p>\n<p>5. Velocit\u00e0 del nastro trasportatore della linea di rivestimento.<\/p>\n<p>In base ai diversi substrati, rivestimenti e distanza di polimerizzazione, la velocit\u00e0 del nastro trasportatore dell'apparecchiatura, ovvero la velocit\u00e0 di polimerizzazione della luce, deve essere regolata in modo appropriato.<\/p>\n<p>(1). La velocit\u00e0 di polimerizzazione \u00e8 troppo elevata, la superficie del substrato \u00e8 appiccicosa o la superficie \u00e8 asciutta ma non asciutta all'interno.<\/p>\n<p>(2). Se la velocit\u00e0 di scorrimento \u00e8 bassa, la superficie del substrato invecchia.<\/p>\n<p>&nbsp;<\/p>\n<p>6, l'ambiente del processo di fotopolimerizzazione.<\/p>\n<p>La viscosit\u00e0 della vernice UV cambia notevolmente a causa della temperatura, quindi la temperatura ambiente dovrebbe essere regolata, generalmente controllata a 15-25 \u2103 \u00e8 pi\u00f9 appropriata, la temperatura troppo bassa produrr\u00e0 il fenomeno della buccia d'arancia, e prestare attenzione alla stampa non pu\u00f2 essere esposta alla luce solare diretta.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong><a
