UV ile k\u00fcrlenen s\u0131v\u0131 kaplamalarla kar\u015f\u0131la\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda, \u0131\u015f\u0131kla k\u00fcrlenen toz kaplamalar\u0131n aktif inceltici, d\u00fc\u015f\u00fck film b\u00fcz\u00fclmesi ve alt tabakaya y\u00fcksek yap\u0131\u015fma \u00f6zelli\u011fi yoktur. I\u015f\u0131kla k\u00fcrlenen toz boyalar, 75~125\u03bcm kal\u0131nl\u0131\u011f\u0131nda m\u00fckemmel kalitede bir kaplama olu\u015fturmak i\u00e7in tek kat halinde uygulanabilir. Bu nedenle, \u0131\u015f\u0131kla sertle\u015fen toz boyalar ayn\u0131 zamanda solvent i\u00e7ermez ve \u00e7evre dostudur ve termoset toz boyalara ve UV s\u0131v\u0131 kaplamalara g\u00f6re daha y\u00fcksek teknik, ekonomik ve ekolojik avantajlara sahiptir.<\/p>\n

I\u015f\u0131kla sertle\u015fen toz boyalar bir ana re\u00e7ine, foto ba\u015flat\u0131c\u0131, pigmentler, dolgu maddeleri, \u00e7e\u015fitli katk\u0131 maddeleri ve benzerlerinden olu\u015fur. Ana re\u00e7ine, \u0131\u015f\u0131kla sertle\u015fen toz boyalar\u0131n ana film olu\u015fturucu maddesidir ve kaplaman\u0131n yap\u0131s\u0131n\u0131 ve kaplama filminin performans\u0131n\u0131 belirleyen ana bile\u015fendir. I\u015f\u0131kla k\u00fcrlenen toz kaplamalar\u0131n form\u00fclasyonu, bir yandan re\u00e7inenin toza iyi bir depolama stabilitesi vermesi gerekirken, di\u011fer yandan kullan\u0131lan hammaddelerin gerekli eriyik viskozitesi ile daha d\u00fc\u015f\u00fck bir s\u0131cakl\u0131kta (100 \u2103 alt\u0131 gibi) olmas\u0131 gerekir. kaplaman\u0131n \u0131\u015f\u0131kla k\u00fcrlenmeden \u00f6nce ve \u0131\u015f\u0131kla k\u00fcrlenme i\u015fleminde iyi ak\u0131\u015f ve tesviye \u00f6zelliklerine sahip olmas\u0131n\u0131 sa\u011flamak i\u00e7in, ard\u0131ndan 120 \u2103 alt\u0131nda \u0131\u015f\u0131kla k\u00fcrlenme reaksiyonu. Geli\u015ftirilen ana re\u00e7ineler genellikle doymam\u0131\u015f polyesterler, vinil eter re\u00e7ineleri, doymam\u0131\u015f polyester akrilatlar, \u00fcretan akrilatlar, epoksi re\u00e7ineleri vb.<\/p>\n

Hiper dall\u0131 polimerler y\u00fcksek i\u015flevselli\u011fe, k\u00fcresel olarak simetrik \u00fc\u00e7 boyutlu yap\u0131ya ve zincir dolanmas\u0131, d\u00fc\u015f\u00fck viskozite, iyi \u00e7\u00f6z\u00fcn\u00fcrl\u00fck, y\u00fcksek aktivite gibi molek\u00fcller aras\u0131 ve molek\u00fcl i\u00e7i yap\u0131 \u00f6zelliklerine sahiptir ve \u00e7oklu fonksiyonel gruplar\u0131n ve di\u011fer \u00f6zelliklerin y\u00fczeyini de\u011fi\u015ftirmek kolayd\u0131r, kaplama filminin performans\u0131n\u0131 art\u0131rmak i\u00e7in kaplamalarda film olu\u015fturucu maddeler, viskozite de\u011fi\u015ftiriciler vb. olarak kullan\u0131labilir.<\/p>\n
