Resim<\/p>\n

Yukar\u0131daki tablodan g\u00f6r\u00fclebilir:
\nG\u00f6r\u00fcn\u00fcm: Ultra ince toz taraf\u0131ndan olu\u015fturulan kaplama filminin y\u00fczeyindeki uzun dalga, s\u0131radan kaba tozdan \u00e7ok daha d\u00fc\u015f\u00fckt\u00fcr, bu da toz kaplamalar\u0131n do\u011fas\u0131nda bulunan portakal kabu\u011fu olgusunu b\u00fcy\u00fck \u00f6l\u00e7\u00fcde ortadan kald\u0131r\u0131r. S\u0131radan toz boyalar\u0131n olu\u015fturdu\u011fu kaplama filminin y\u00fczeyi yeterince d\u00fcz de\u011fildir ve ultra ince toz boyalar\u0131n olu\u015fturdu\u011fu kaplama filminin y\u00fczey parlakl\u0131\u011f\u0131 \u00e7ok daha y\u00fcksektir, bu da y\u00fcksek dekoratif gereksinimleri kar\u015f\u0131layabilir.<\/p>\n

Mekanik \u00f6zellikler: ince tozun ince kaplamas\u0131 ve kaba tozun kal\u0131n kaplamas\u0131 yap\u0131\u015fma, korozyon direnci vb. a\u00e7\u0131s\u0131ndan ayn\u0131 etkiye sahiptir. \u0130nce tozun ince kaplamas\u0131 daha iyi kalem sertli\u011fine ve darbe direncine sahiptir. Ayn\u0131 kal\u0131nl\u0131k alt\u0131nda, ince tozdan olu\u015fan kaplama daha iyi korozyon direncine sahiptir.<\/p>\n

Tesviye: ultra ince toz kaplama partik\u00fcl boyutu daha k\u00fc\u00e7\u00fckt\u00fcr, aglomerasyon problemini \u00e7\u00f6zd\u00fckten sonra, as\u0131l\u0131 kalma problemini ortaya \u00e7\u0131karmak kolay de\u011fildir, ak\u0131\u015fkanla\u015ft\u0131rma performans\u0131 \u00e7ok m\u00fckemmeldir, s\u0131radan kaba toz ile kar\u015f\u0131la\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda, kaplama filminin olu\u015fumu daha d\u00fczd\u00fcr.<\/p>\n

\u0130n\u015faat performans\u0131: ultra ince toz boyalar, daha k\u00fc\u00e7\u00fck partik\u00fcl boyutu nedeniyle daha ince kaplamalar olu\u015fturabilir, bu nedenle alt tabakan\u0131n ayn\u0131 alan\u0131n\u0131 kaplar, sadece hammadde miktar\u0131 b\u00fcy\u00fck \u00f6l\u00e7\u00fcde azalmaz ve y\u00fczey p\u00fcr\u00fczl\u00fcl\u00fc\u011f\u00fc de \u00f6nemli \u00f6l\u00e7\u00fcde azal\u0131r. \u00c7ok p\u00fcr\u00fczl\u00fc bir alt tabaka ultra ince toz boya ile kaplanm\u0131\u015f olsa bile, s\u0131radan kaba tozla yap\u0131lamayan belirgin bir portakal kabu\u011fu olmayacakt\u0131r.<\/p>\n

Ve ultra ince tozun ince kaplamas\u0131 daha h\u0131zl\u0131 kurur, zamandan tasarruf sa\u011flar ve 2 veya 3 kat s\u0131radan kaba toz ve ultra ince toz p\u00fcsk\u00fcrt\u00fcld\u00fckten sonra in\u015faat haftas\u0131n\u0131 k\u0131salt\u0131r, s\u0131radan kaba tozun kal\u0131n kaplama nedeniyle \u00f6rtme g\u00fcc\u00fc sorunu yoktur ve ultra ince tozun ince kaplamas\u0131 yetersiz \u00f6rtme g\u00fcc\u00fcne sahip gibi g\u00f6r\u00fcn\u00fcr, bu nedenle uygun kal\u0131n kaplamay\u0131 uygulamay\u0131 veya g\u00fc\u00e7l\u00fc \u00f6rtme g\u00fcc\u00fcne sahip pigmenti se\u00e7meyi se\u00e7ebilirsiniz, ancak eklenen pigment miktar\u0131n\u0131n \u00e7ok fazla olmamas\u0131na dikkat etmelisiniz, aksi takdirde d\u00fczensiz bir \u015fekilde kayna\u015fm\u0131\u015f fenomen olacakt\u0131r.<\/p>\n

(5) Depolama stabilitesi
\nToz akrilik re\u00e7inenin depolanmas\u0131 ve ta\u015f\u0131nmas\u0131 kolayd\u0131r, ta\u015f\u0131ma maliyeti solvent bazl\u0131 akrilik re\u00e7ineden daha d\u00fc\u015f\u00fckt\u00fcr, depolama ve ta\u015f\u0131ma i\u015flemi g\u00fcvenlidir. Bununla birlikte, toz boyalar\u0131n boya depolama ve ta\u015f\u0131ma i\u015flemi bas\u0131nc\u0131 veya yap\u0131\u015fmaya neden olan nem gibi baz\u0131 yayg\u0131n dezavantajlar\u0131 vard\u0131r, d\u00fc\u015f\u00fck s\u0131cakl\u0131klarda ve kuru tozda tutulmas\u0131 gerekir.<\/p>\n

Toz akrilik re\u00e7ine, in\u015faat birimi taraf\u0131ndan daha kolay kabul edilir ve baz\u0131 kat\u0131 akrilik re\u00e7ine modelleri tiksotropiktir, boyadan yap\u0131lm\u0131\u015ft\u0131r ve s\u0131radan lateks boya, kutuyu a\u00e7ma ve in\u015faat performans\u0131nda ayn\u0131 etkiye sahiptir. Y\u00fcksek dereceli kat\u0131 akrilik re\u00e7ine, \u00e7\u00fcnk\u00fc ana monomer metakrilatt\u0131r, ultraviyole radyasyonda bozulmaz, bu nedenle hava direnci daha belirgindir. S\u0131radan solvent bazl\u0131 termoplastik akrilik re\u00e7ineye ula\u015fmas\u0131 zor olan 170 \u2103 veya daha fazla re\u00e7ine termal stabilitesi, 260 \u2103'ye kadar bireysel \u00e7e\u015fitler.<\/p>\n

4, Sonu\u00e7<\/p>\n

\u00d6zetle, ultra ince akrilik toz boyalar ve kaplaman\u0131n bir dizi avantaj\u0131 vard\u0131r: k\u00fc\u00e7\u00fck kirlilik; iyi \u0131\u015f\u0131k ve renk tutma, m\u00fckemmel dekoratif; elektrostatik kaplama etkisi iyidir, ince kaplanabilir; p\u00fcsk\u00fcrtme verimlili\u011fi y\u00fcksektir, toz geri d\u00f6n\u00fc\u015ft\u00fcr\u00fclebilir; astars\u0131z iyi yap\u0131\u015fma; \u0131s\u0131 direnci, bordo direnci, kimyasal diren\u00e7, sararmas\u0131 kolay de\u011fil; iyi fiziksel ve mekanik \u00f6zellikler.<\/p>\n

Ultra ince toz boyalar, toz boyalar\u0131n kullan\u0131ld\u0131\u011f\u0131 t\u00fcm alanlarda yayg\u0131n olarak kullan\u0131labilir ve otomotiv alan\u0131ndaki son derece dekoratif kaplama gereksinimleri, d\u0131\u015f mekan \u00fcr\u00fcnleri i\u00e7in y\u00fcksek hava ko\u015fullar\u0131na dayan\u0131kl\u0131l\u0131k gereksinimleri, gemi ve konteyner alan\u0131ndaki korozyon direnci gereksinimleri, mobilya ve ev aletleri i\u00e7in dekoratif ve ekonomik gereksinimler ve ince alet bile\u015fenleri i\u00e7in ultra ince kaplama gereksinimleri gibi daha kat\u0131 gereksinimleri kar\u015f\u0131layabilir.<\/p>\n

Ultra ince akrilik toz boyalar\u0131n \u00e7evre korumas\u0131, ekonomisi ve \u00fcst\u00fcn performans\u0131, uygulama alanlar\u0131n\u0131 geni\u015fletecek, kapsaml\u0131 geli\u015fme beklentileri ve b\u00fcy\u00fck pazar potansiyeli, toz boya end\u00fcstrisi i\u00e7in yeni bir geli\u015fme f\u0131rsatlar\u0131 turu getirecektir.<\/p>\n
