1. K\u0131rma i\u00e7in titanyum dioksit gereklilikleri<\/p>\n
Pigment<\/a> olarak kullan\u0131lan titanyum dioksit, m\u00fckemmel optik \u00f6zelliklere ve kararl\u0131 kimyasal \u00f6zelliklere sahiptir. Titanyum dioksit, par\u00e7ac\u0131k boyutu, par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131 ve safl\u0131k konusunda \u00e7ok y\u00fcksek gereksinimlere sahiptir. Genel olarak, titanyum dioksitin par\u00e7ac\u0131k boyutu, g\u00f6r\u00fcn\u00fcr \u0131\u015f\u0131\u011f\u0131n dalga boyu aral\u0131\u011f\u0131na, yani 0.15m ~ 0.35m’ye ba\u011fl\u0131d\u0131r. Ve beyaz bazik bir pigment<\/a> olarak, safs\u0131zl\u0131klar\u0131n, \u00f6zellikle demir safs\u0131zl\u0131klar\u0131n\u0131n art\u0131\u015f\u0131na kar\u015f\u0131 \u00e7ok hassast\u0131r ve toz haline getirildi\u011finde art\u0131\u015f\u0131n 5 ppm’den az olmas\u0131 gerekir. Ayr\u0131ca, farkl\u0131 kaplama sistemlerinde iyi da\u011f\u0131labilirli\u011fe sahip olmas\u0131 i\u00e7in titanyum dioksit de gereklidir. Bu nedenle, genel mekanik k\u0131rma ekipman\u0131n\u0131n gereksinimleri kar\u015f\u0131lamas\u0131 zordur, bu nedenle titanyum dioksitin nihai olarak ezilmesi (bitmi\u015f \u00fcr\u00fcn k\u0131rma), \u015fu anda yurti\u00e7inde ve yurtd\u0131\u015f\u0131nda jet de\u011firmenler kullan\u0131lmaktad\u0131r.<\/p>\n 2. Titanyum dioksit \u00fcretimi i\u00e7in jet de\u011firmen se\u00e7imi<\/p>\n Titanyum dioksitin k\u0131rma gereksinimlerine g\u00f6re: dar par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131, inkl\u00fczyonlarda daha az art\u0131\u015f, iyi da\u011f\u0131labilirlik, vb. ve titanyum dioksitin malzeme \u00f6zellikleri: y\u00fcksek viskozite, zay\u0131f ak\u0131\u015fkanl\u0131k, ince par\u00e7ac\u0131k boyutu ve kolay duvar ba\u011flant\u0131s\u0131, vb. titanyum dioksit i\u00e7in nihai k\u0131rma ekipman\u0131 olarak kullan\u0131lan y\u00fcksek seviyeli d\u00fcz tip (yatay disk tipi olarak da bilinir) jet de\u011firmen;<\/p>\n Ve k\u0131rma ortam\u0131 olarak a\u015f\u0131r\u0131 \u0131s\u0131t\u0131lm\u0131\u015f buhar kullan\u0131n. Buhar\u0131n elde edilmesi kolay ve ucuz oldu\u011fu i\u00e7in, buhar \u00e7al\u0131\u015fma ortam\u0131n\u0131n bas\u0131nc\u0131 bas\u0131n\u00e7l\u0131 havan\u0131nkinden \u00e7ok daha y\u00fcksektir ve y\u00fckseltilmesi de kolayd\u0131r, bu nedenle buhar\u0131n kinetik enerjisi bas\u0131n\u00e7l\u0131 havan\u0131nkinden daha b\u00fcy\u00fckt\u00fcr. Ayn\u0131 zamanda, a\u015f\u0131r\u0131 \u0131s\u0131t\u0131lm\u0131\u015f buhar\u0131n temizli\u011fi, d\u00fc\u015f\u00fck viskozite ve statik elektrik i\u00e7ermeyen bas\u0131n\u00e7l\u0131 havadan daha y\u00fcksektir. Ayr\u0131ca, ezme s\u0131ras\u0131nda malzeme \u00e7arp\u0131\u015fmas\u0131 ve s\u00fcrt\u00fcnmesinden kaynaklanan statik elektri\u011fi ortadan kald\u0131rabilir ve toz halindeki malzemelerin ikincil kohezyonunu azaltabilir. Ek olarak, y\u00fcksek s\u0131cakl\u0131kta ezme, titanyum dioksitin uygulama da\u011f\u0131labilirli\u011fini iyile\u015ftirebilir ve titanyum dioksitin ak\u0131\u015fkanl\u0131\u011f\u0131n\u0131 art\u0131rabilir. K\u0131zg\u0131n buhar\u0131n enerji t\u00fcketimi d\u00fc\u015f\u00fckt\u00fcr, bu da bas\u0131n\u00e7l\u0131 havan\u0131n sadece %30 ila %65’i kadard\u0131r.<\/p>\n Ek olarak, d\u00fcz bir jet de\u011firmen kullan\u0131larak, farkl\u0131 uygulama sistemlerinde titanyum dioksitin da\u011f\u0131labilirli\u011fini art\u0131rmak i\u00e7in titanyum dioksitin y\u00fczeyini organik olarak de\u011fi\u015ftirmek \u00fczere toz haline getirirken organik katk\u0131 maddeleri eklenebilir.<\/p>\n <\/p>\n 3. Jet freze ekipman\u0131n\u0131 etkileyen fakt\u00f6rler<\/p>\n (1) Jet de\u011firmen: Jet de\u011firmenin en \u00f6nemli ekipman\u0131 olan jet de\u011firmenin kalitesi do\u011frudan \u00fcr\u00fcn\u00fcn kalitesini belirler. Gaz tozu makinesinin, y\u00fcksek darbe kinetik enerjisi, iyi s\u0131n\u0131fland\u0131rma etkisi, a\u015f\u0131nma direnci ve y\u00fcksek s\u0131cakl\u0131k direnci ile makul bir \u015fekilde tasarlanm\u0131\u015f, iyi yap\u0131lm\u0131\u015f olmas\u0131 gerekir. Bu nedenle, bir gaz tozu makinesi se\u00e7mek \u00e7ok \u00f6nemlidir.<\/p>\n (2) Buhar kalitesi: Jet \u00f6\u011f\u00fctmenin k\u0131rma ortam\u0131 a\u015f\u0131r\u0131 \u0131s\u0131t\u0131lm\u0131\u015f buhard\u0131r. Buhar kalitesi k\u0131rma gereksinimlerini kar\u015f\u0131lam\u0131yorsa, gaz tozunun kalitesini ciddi \u015fekilde etkiler. Genel olarak, gaz tozu makinesinin buhar gereksinimleri \u015funlard\u0131r: bas\u0131n\u00e7 1,6-2,0 MPa ve s\u0131cakl\u0131k 290 \u00b0 C ile 310 \u00b0 C aras\u0131ndad\u0131r. S\u0131cakl\u0131k ve bas\u0131n\u00e7 gereksinimlerden d\u00fc\u015f\u00fckse, darbe kinetik enerjisi d\u00fc\u015f\u00fck olacak, k\u0131rma kuvveti azalacak, sistemin \u0131s\u0131s\u0131 yeterli olmayacak, malzeme nemden ve di\u011fer bir\u00e7ok olumsuz fakt\u00f6rden kolayca etkilenecek, bu da k\u0131rma etkisini etkileyecek, sistemi bloke edecek ve \u00e7al\u0131\u015fmaz hale getirecektir. normal \u015fekilde \u00e7al\u0131\u015fmak; s\u0131cakl\u0131k ve bas\u0131n\u00e7 \u00e7ok y\u00fcksek ise, sistem i\u00e7indeki ekipmana zarar verir.<\/p>\n (3) Proses kontrol\u00fc: Jet \u00f6\u011f\u00fctme, istikrarl\u0131 ve s\u00fcrekli \u00e7al\u0131\u015fma gerektirir ve buhar ve besleme miktar\u0131n\u0131n dalgalanmas\u0131 belirli bir aral\u0131kta kontrol edilmelidir. Ayar yava\u015f\u00e7a yap\u0131lmal\u0131 ve aniden b\u00fcy\u00fck veya k\u00fc\u00e7\u00fck olmas\u0131 kesinlikle yasakt\u0131r. Ek olarak, hava-toz sistemi normale d\u00f6nd\u00fc\u011f\u00fcnde s\u00fcrekli \u00e7al\u0131\u015fmaya devam etmeli ve s\u0131k s\u0131k ara\u00e7 kullanmaktan ve park etmekten ka\u00e7\u0131nmal\u0131d\u0131r. Ayr\u0131ca, ara\u00e7 kullan\u0131rken ve park ederken \u00e7al\u0131\u015ft\u0131rma prosed\u00fcrlerine kesinlikle uyulmal\u0131d\u0131r.<\/p>\n (4) Sistem izleme: Sistemin normal \u00e7al\u0131\u015fmas\u0131n\u0131 sa\u011flamak i\u00e7in, gerekli izleme ekipman\u0131, durumdaki de\u011fi\u015fikliklere g\u00f6re zaman\u0131nda ayarlamalar\u0131n yap\u0131labilmesi i\u00e7in sistemin makul bir konumuna kurulmal\u0131d\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":" Jet de\u011firmen: Jet de\u011firmen i\u00e7in en \u00f6nemli ekipman olan jet de\u011firmenin kalitesi, \u00fcr\u00fcn\u00fcn kalitesini do\u011frudan belirler.<\/p>\n","protected":false},"author":7,"featured_media":108247,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[851],"tags":[],"class_list":["post-127141","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-endustri-haberleri-tr"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.alpapowder.com\/tr\/wp-json\/wp\/v2\/posts\/127141","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.alpapowder.com\/tr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.alpapowder.com\/tr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.alpapowder.com\/tr\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.alpapowder.com\/tr\/wp-json\/wp\/v2\/comments?post=127141"}],"version-history":[{"count":0,"href":"https:\/\/www.alpapowder.com\/tr\/wp-json\/wp\/v2\/posts\/127141\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.alpapowder.com\/tr\/wp-json\/wp\/v2\/media\/108247"}],"wp:attachment":[{"href":"https:\/\/www.alpapowder.com\/tr\/wp-json\/wp\/v2\/media?parent=127141"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.alpapowder.com\/tr\/wp-json\/wp\/v2\/categories?post=127141"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.alpapowder.com\/tr\/wp-json\/wp\/v2\/tags?post=127141"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
