style="text-indent:25px">銅金粉的現(xiàn)狀，現(xiàn)在的形勢(shì)就是這樣的逼人，你不思進(jìn)取，就只能看著別人的產(chǎn)品**。你想等別人弄好了再想法跟，這樣做是很保險(xiǎn)，但人付出的代價(jià)也不會(huì)低，一個(gè)成熟的技術(shù)，其技術(shù)含量是有價(jià)的，而且持有者輕易是不會(huì)出手的，要不。國(guó)內(nèi)就不會(huì)在引進(jìn)設(shè)備的時(shí)候不引進(jìn)專有技術(shù)了。銅金粉作為一種常用的金屬顏料，在印刷、油漆及涂料等行業(yè)得到應(yīng)用。典型的銅金粉的制造工藝是霧化-球磨法,即將金屬或其合金熔化噴霧使之成為顆粒,然后在球磨機(jī)里將顆粒金屬粉末沖擊研磨成微細(xì)的金屬鱗片。</p><p style="text-indent:25px">銅金粉片厚對(duì)光澤度的影響：銅金粉片的平均厚度可按下式計(jì)算[6]:δ=1/(Pc·ρm)(2)式中:δ為銅金粉片的厚度,cm;Pc為銅金粉的水面遮蓋率,cm2/g;ρm為銅金粉的密度,g/cm3。試驗(yàn)測(cè)得進(jìn)口銅金粉的Pc=12400cm2/g,ρm=8.36g/cm3;國(guó)產(chǎn)銅金粉的Pc=9280cm2/g,ρm=8.36g/cm3。把它們分別代入(2)式,得到進(jìn)口、國(guó)產(chǎn)銅金粉的厚度分別為9.6×10-4cm(即0.096μm)、12.89×10-4cm(即0.13μm)。由此可見,無論是國(guó)產(chǎn)粉還是進(jìn)口粉,它們的估算厚度與實(shí)驗(yàn)觀測(cè)厚度接近,這充分說明了所采用的銅金粉厚度測(cè)試方法的可靠性與準(zhǔn)確性。一般來說,寫對(duì)聯(lián)的金漆是用銅金粉、天拿水和酚醛清漆三合一攪勻來寫的。</p><div
