style="text-indent:25px">銅金粉的微觀形貌及粒度分布，銅金粉粒子為鱗片狀結(jié)構(gòu)，在掃描電鏡下觀察發(fā)現(xiàn)，銅金粉的鱗片多數(shù)是不規(guī)則的，邊緣呈鋸齒形狀，少量是較為規(guī)則的圓形。這種粒子結(jié)構(gòu)決定了它有與被涂物平行排列的特性。銅金粉的光學(xué)特性作為金屬顏料之一的銅鋅合金粉主要的一個特點就是有“隨角異色”現(xiàn)象，不同的角度會有不同的顏色、明度、飽和度，是顏料對入射光的不同散射和反射方式引起的，該現(xiàn)象與金屬表面的平整度有關(guān)，材料表面越平整，亮度就越高。影響銅金粉印金光澤度的因素是多方面的，其中銅金粉的微觀形貌、片厚及其在粘結(jié)料中的定向排列起著至關(guān)重要的作用。徐州銅金粉技術(shù)不同細度的粉末反光能力不同，色相不一致。</p><div

style="text-indent:25px">銅金粉涂料的罩光層在金屬粉末涂膜上再噴涂罩光層具有以下優(yōu)點:增強金屬粉末涂膜的抗石擊性能;增加金屬粉末涂膜的美觀效果;徹底解決金屬顏料的可擦落性;提高金屬粉末涂膜的耐候性。為保證罩光層的外觀效果,要求經(jīng)***次噴涂的工件不能受到任何的污染。因此,一般需要有全自動化的噴涂線和兩套**的噴房進行分別涂裝。建議一般情況下不要噴涂罩光層。只有在要求非常高時才使用,如:***家電、汽車輪轂以及戶外用途(確保耐候性)等。希望以上信息可以對你有所幫助。</p><p style="text-indent:25px">銅金粉類,是一種高級金屬顏料,調(diào)入金油或清漆后即生成鮮艷奪目的金墨或金漆,在化工、印刷、紡織、印花、建筑裝璜、工藝飾品、包裝材料等行業(yè)得到普遍應(yīng)用。銅金粉是一種浮型片狀顏料,由一定比例的銅、鋅和鋁合金,經(jīng)熔煉、球磨、分級到所需要的規(guī)格和效果而成。銅金粉的色相可分為青金、紅金、古銅金等。銅金粉以色相分為青光、青紅光、紅光三種,特殊需要可根據(jù)不同比例相拼。近年來還開發(fā)了新品凹印金條,是防止污染環(huán)境的一種環(huán)保型產(chǎn)品,便于安全運輸。銅金粉顏料可直接與底粉混合，添加比例視具體情況而定，其色澤和閃光性比珠光顏料要弱一些。</p><div

style="text-indent:25px">銅金粉又叫金粉，是以銅鋅合金為原料，經(jīng)過特殊的機械技工和表面化學(xué)處理制得的，具有鱗片狀結(jié)構(gòu)，能夠在粘結(jié)料中漂浮，呈現(xiàn)黃金光澤，具有顏料性質(zhì)的一種金屬顏料。平常我們看到的高級畫報、好的包裝、高級印刷品、特殊場合使用的印刷品、過年門口貼的對聯(lián)，金色部分一般是用銅金粉著色。凹版印刷經(jīng)常要用到金屬顏料銅金粉，因為它輝煌的金屬光澤，有烘托主體和引人矚目的效果。加上中國人對金色本來就情有獨鐘。金屬顏料銅金粉按目數(shù)，也就是金粉的大小來分，常用的有：200目，400目，600目，800目，1000目，1200目，1500目。根據(jù)目數(shù)的大小，織物印金，快速印刷，絲網(wǎng)印刷，金漆，工藝品涂層，噴霧膠漆等。銅金粉末涂料用于粉末涂料的銅金粉實際上不含金，主要成分是金屬銅。徐州銅金粉技術(shù)</p><p

style="text-indent:25px">銅金粉的純度：常用的高含量銅的測定方法仍為古老的碘量法，其碘化鉀的用量大、成本高、耗時多，而新近開發(fā)的光度法又因銅顯色劑的問題不宜于高含量銅的測定，故有必要研究、開發(fā)新的顯色劑。該文作者試用醋酸-醋酸鈉緩沖溶液控制pH值，用乙二胺四乙酸二鈉鹽（EDTA）作顯色劑，測定銅金粉中的高含量銅，同時利用EDTA掩蔽鋅、鋁等元素以消除其干擾。Cu^2+與EDTA生成摩爾比1：1的藍色絡(luò)合物，該絡(luò)合物的吸收波長為2=730nm，摩爾吸光系數(shù)為ε=88．9，銅離子含量在12-24mg/50mL范圍內(nèi)呈良好的線性關(guān)系，線性回歸方程為A=0．0354+0．02317c，線性相關(guān)系數(shù)R=0．9995。采用EDTA分光光度法測定銅金粉中的高含量銅，所得結(jié)果令人滿意，有開發(fā)應(yīng)用前景，尤其適用于設(shè)備比較簡陋的中、小型企業(yè)實驗室。徐州銅金粉技術(shù)</p></p><br
