I\u015f\u0131kla sertle\u015fen UV kaplamalar\u0131n bile\u015fen hammaddeleri nelerdir?<\/strong><\/h1>\n

Ultraviyole k\u00fcrleme (UV) kaplama yeni bir \u00e7evre dostu kaplama t\u00fcr\u00fcd\u00fcr. Son derece h\u0131zl\u0131 bir kuruma oran\u0131na sahiptir ve y\u00fcksek bir \u00fcretim verimlili\u011fi ile UV \u0131\u015f\u0131\u011f\u0131 ile sadece birka\u00e7 saniye i\u00e7inde k\u00fcrlenebilir.
\nUV ile k\u00fcrlenen kaplamalar temel olarak oligomerler, reaktif seyrelticiler, fotoba\u015flat\u0131c\u0131lar ve katk\u0131 maddelerinden olu\u015fur.<\/p>\n

1. UV Oligomer<\/strong><\/span><\/a>
\nFilm olu\u015fturucu bile\u015fik, kaplamadaki ak\u0131\u015fkan bile\u015fen olan kaplaman\u0131n ana bile\u015fimidir. Kaplama filmi performans\u0131, yap\u0131 performans\u0131 ve kaplaman\u0131n di\u011fer \u00f6zel \u00f6zellikleri esas olarak film olu\u015fturucu bile\u015fi\u011fe ba\u011fl\u0131d\u0131r. UV kaplama film olu\u015fturucu bile\u015fik oligomerdir, performans\u0131 temel olarak k\u00fcrlenmeden \u00f6nce kaplaman\u0131n yap\u0131 performans\u0131n\u0131 ve \u0131\u015f\u0131kla k\u00fcrlenme oran\u0131n\u0131, k\u00fcrlenmeden sonra kaplama film performans\u0131n\u0131 ve di\u011fer \u00f6zel \u00f6zelliklerini belirler.
\nUV kaplamalar esas olarak serbest radikal \u0131\u015f\u0131k k\u00fcrleme sistemleridir, bu nedenle kullan\u0131lan oligomerler \u00e7e\u015fitli akrilik re\u00e7inelerdir. Katyonik UV kaplama oligomerleri epoksi re\u00e7ineleri ve vinil eter bile\u015fikleridir.<\/p>\n

2. Aktif seyrelticiler
\nAktif seyrelticiler, viskoziteyi seyreltebilen ve azaltabilen ve ayn\u0131 zamanda k\u00fcrlenmi\u015f filmin performans\u0131n\u0131 ayarlama yetene\u011fine sahip olan UV kaplamalar\u0131n bir ba\u015fka \u00f6nemli bile\u015fenidir. Akrilat fonksiyonel monomer y\u00fcksek reaktiviteye ve d\u00fc\u015f\u00fck u\u00e7uculu\u011fa sahiptir, bu nedenle UV kaplamalarda yayg\u0131n olarak kullan\u0131l\u0131r. akrilatlar genellikle UV kaplamalar i\u00e7in aktif seyrelticiler olarak kullan\u0131l\u0131r ve ger\u00e7ek form\u00fclasyonda, performanslar\u0131n\u0131 tamamlay\u0131c\u0131 hale getirmek ve iyi bir genel etki elde etmek i\u00e7in tek, \u00e7ift ve \u00e7ok fonksiyonlu akrilatlar birlikte kullan\u0131lacakt\u0131r.<\/p>\n

3. Fotoba\u015flat\u0131c\u0131<\/strong><\/span><\/a>
\nFotoba\u015flat\u0131c\u0131, UV kaplamalarda \u00f6zel bir kataliz\u00f6rd\u00fcr, UV kaplamalar\u0131n \u0131\u015f\u0131kla k\u00fcrlenme oran\u0131n\u0131 belirlemek i\u00e7in UV kaplamalar\u0131n \u00f6nemli bir bile\u015fenidir.
\nFor colorless varnish UV coatings, photoinitiators are often used 1173, 184, 651 and BP\/tertiary amine. 184 high activity, low odor, yellowing resistance, is the preferred photoinitiator for yellowing resistant UV coatings, in order to improve the light curing rate, often used in conjunction with Fotoba\u015flat\u0131c\u0131 TPO<\/a>.
\nFor colored UV coatings, photoinitiators such as ITX, 907, 369, Fotoba\u015flat\u0131c\u0131 TPO<\/a>, ve Fotoba\u015flat\u0131c\u0131 819<\/a> are commonly used. Sometimes UV coatings in order to reduce oxygen blocking, improve the light curing rate, often into a small amount of active amine.<\/p>\n

4. Katk\u0131 maddeleri
\nYard\u0131mc\u0131 madde, UV kaplaman\u0131n yard\u0131mc\u0131 bile\u015fenidir. Katk\u0131 maddelerinin rol\u00fc, kaplamalar\u0131n i\u015fleme performans\u0131n\u0131, depolama performans\u0131n\u0131 ve yap\u0131m performans\u0131n\u0131 iyile\u015ftirmek, film performans\u0131n\u0131 iyile\u015ftirmek ve filme baz\u0131 \u00f6zel \u00f6zellikler kazand\u0131rmakt\u0131r. UV kaplamalarda yayg\u0131n olarak kullan\u0131lan katk\u0131 maddeleri k\u00f6p\u00fck kesici, tesviye maddesi, \u0131slat\u0131c\u0131 ve da\u011f\u0131t\u0131c\u0131 madde, yap\u0131\u015fma artt\u0131r\u0131c\u0131, matla\u015ft\u0131r\u0131c\u0131 madde, diren\u00e7 vb. olup UV kaplamalarda farkl\u0131 bir rol oynarlar.<\/p>\n

UV yaz\u0131c\u0131n\u0131n kokusu zehirli midir?<\/strong><\/h2>\n

UV yaz\u0131c\u0131, ye\u015fil \u00e7evreye yan\u0131t veren bir t\u00fcr bask\u0131 ekipman\u0131d\u0131r. UV yaz\u0131c\u0131 k\u00fcrleme y\u00f6nteminin benzersizli\u011fi nedeniyle, UV \u0131\u015f\u0131k k\u00fcrleme i\u015fleminde bir miktar koku olu\u015fmas\u0131 ka\u00e7\u0131n\u0131lmazd\u0131r. UV yaz\u0131c\u0131 sat\u0131n alm\u0131\u015f veya almay\u0131 planlayan bir\u00e7ok arkada\u015f\u0131n kafas\u0131nda kokuyla ilgili \u015f\u00f6yle sorular var: koku zehirli mi, bununla nas\u0131l ba\u015fa \u00e7\u0131k\u0131l\u0131r?<\/p>\n

Elbette, kullan\u0131c\u0131n\u0131n kokuyla ilgili endi\u015fesi normaldir, \u00f6zellikle UV yaz\u0131c\u0131 bask\u0131 s\u00fcreci hakk\u0131nda \u00e7ok net olmayanlar, geni\u015f formatl\u0131 malzemeleri basmak i\u00e7in d\u00fcz yatakl\u0131 bir UV yaz\u0131c\u0131 kullan\u0131rken koku daha belirgin olacakt\u0131r. Yukar\u0131daki sorular\u0131 yan\u0131tlamak i\u00e7in \u00f6ncelikle UV yaz\u0131c\u0131 m\u00fcrekkebinin bile\u015fimini anlamal\u0131y\u0131z. Sonu\u00e7ta, kokunun kayna\u011f\u0131 UV m\u00fcrekkebinde yatmaktad\u0131r.<\/p>\n

 <\/p>\n

UV m\u00fcrekkep esas olarak fotoba\u015flat\u0131c\u0131lar, reaktif seyrelticiler, oligomerler ve \u00e7e\u015fitli katk\u0131 maddelerinden olu\u015fur. UV yaz\u0131c\u0131 m\u00fcrekkep katman\u0131 \u015fu \u015fekilde olu\u015fur: fotoba\u015flat\u0131c\u0131lar, serbest radikaller veya katyonlar \u00fcretmek i\u00e7in UV \u0131\u015f\u0131\u011f\u0131n\u0131 emerek reaktif seyrelticilere ve oligomerlerin polimerizasyon \u00e7apraz ba\u011flanma reaksiyonuna neden olur. Koku esas olarak UV m\u00fcrekkep akrilatlar\u0131ndan, ayn\u0131 zamanda katk\u0131 maddelerinden de az miktarda gelir. Koku k\u0131sa bir s\u00fcre i\u00e7inde yava\u015f\u00e7a kaybolur ve sonunda kaybolur ve insanlar i\u00e7in ger\u00e7ekten zararl\u0131d\u0131r ve kur\u015fun, kadmiyum, c\u0131va, alt\u0131 de\u011ferlikli krom gibi a\u011f\u0131r metallerin yan\u0131 s\u0131ra polibromlu bifeniller, polibromlu difenil eterler, ftalatlar ve di\u011fer u\u00e7ucu y\u00fcksek, koku, alerjiye e\u011filimli maddeler i\u00e7eri\u011fine dikkat etmelidir. standard\u0131 a\u015f\u0131yor. \u015eu anda, d\u00fczenli m\u00fcrekkep \u00fcreticileri yukar\u0131daki maddelerin test raporlar\u0131n\u0131 sa\u011flayabilir.<\/p>\n

UV m\u00fcrekkebinin bile\u015fimini, kokunun kayna\u011f\u0131n\u0131 ve hangi zararl\u0131 bile\u015fenleri tespit etmeye odakland\u0131\u011f\u0131m\u0131z\u0131 bildi\u011fimizden, ger\u00e7ek \u00fcr\u00fcn se\u00e7iminde, bask\u0131 \u00fcretiminde yaln\u0131zca a\u015fa\u011f\u0131dakileri yapmam\u0131z gerekir, zehirlenme veya insan v\u00fccuduna di\u011fer ciddi zararlar konusunda endi\u015felenemezsiniz. Her \u015feyden \u00f6nce, garantili bir UV yaz\u0131c\u0131 \u00fcreticisi markas\u0131 se\u00e7meli, uyumlu m\u00fcrekkeplerini se\u00e7meliyiz, test raporlar\u0131 yay\u0131nlamalar\u0131na izin vermek en iyisidir; ikincisi, kokunun zehirli olup olmad\u0131\u011f\u0131na bak\u0131lmaks\u0131z\u0131n, sigorta ve operat\u00f6r konforu hususlar\u0131 i\u00e7in, \u00fcretim ortam\u0131n\u0131n iyi havaland\u0131rmaya sahip olmas\u0131 i\u00e7in kullan\u0131lmas\u0131, \u00fcnitenin ko\u015fullar\u0131 baz\u0131 eldivenler, maskeler ve di\u011fer koruyucu ekipmanlarla yap\u0131land\u0131r\u0131labilir; son olarak, \"ikincil kirlili\u011fi\" \u00f6nlemek i\u00e7in geri d\u00f6n\u00fc\u015f\u00fcm\u00fc veya bertaraf\u0131 kolayla\u015ft\u0131rmak i\u00e7in at\u0131klar\u0131n bas\u0131lmas\u0131.<\/p>\n
