黃銅顏色深好還是淺好？黃銅顏色評定方法

黃(huang)銅(tong)顏色是什么顏色？如何檢(jian)測(ce)黃(huang)銅(tong)的顏色？黃(huang)銅(tong)含銅(tong)量不同，其外觀顏色也(ye)會有所差別，為了準確的評定(ding)黃(huang)銅(tong)顏色，就可以(yi)利用(yong)對(dui)色燈箱進行目(mu)視檢(jian)測(ce)。

黃銅顏色(se)深好還是淺(qian)好？

銅(tong)(tong)(tong)(tong)是(shi)(shi)少數有顏(yan)(yan)色(se)(se)(se)(se)(se)(se)的(de)(de)金(jin)屬(shu)之一(yi)，純銅(tong)(tong)(tong)(tong)在約700毫微米波長有較(jiao)高(gao)的(de)(de)反射率(lv)而呈(cheng)現橙紅。銅(tong)(tong)(tong)(tong)極易(yi)與(yu)其(qi)它元素形成合金(jin)，不(bu)(bu)同(tong)的(de)(de)合金(jin)，不(bu)(bu)同(tong)的(de)(de)元素含(han)量(liang)(liang)又(you)具有不(bu)(bu)同(tong)的(de)(de)色(se)(se)(se)(se)(se)(se)澤(ze)。銅(tong)(tong)(tong)(tong)與(yu)鋅(xin)(xin)的(de)(de)合金(jin)稱為黃(huang)(huang)(huang)(huang)銅(tong)(tong)(tong)(tong)，隨著(zhu)鋅(xin)(xin)含(han)量(liang)(liang)的(de)(de)增加，黃(huang)(huang)(huang)(huang)銅(tong)(tong)(tong)(tong)顏(yan)(yan)色(se)(se)(se)(se)(se)(se)由紅變為金(jin)黃(huang)(huang)(huang)(huang)。銅(tong)(tong)(tong)(tong)與(yu)鋁、錫等元素形成的(de)(de)合金(jin)稱為青銅(tong)(tong)(tong)(tong)，其(qi)顏(yan)(yan)色(se)(se)(se)(se)(se)(se)為黃(huang)(huang)(huang)(huang)帶(dai)綠色(se)(se)(se)(se)(se)(se)澤(ze)。黃(huang)(huang)(huang)(huang)銅(tong)(tong)(tong)(tong)是(shi)(shi)銅(tong)(tong)(tong)(tong)鋅(xin)(xin)合金(jin)，根據含(han)銅(tong)(tong)(tong)(tong)量(liang)(liang)的(de)(de)不(bu)(bu)同(tong)導致市場上的(de)(de)黃(huang)(huang)(huang)(huang)銅(tong)(tong)(tong)(tong)種類千差萬別，一(yi)般(ban)說來(lai)，含(han)銅(tong)(tong)(tong)(tong)量(liang)(liang)大于60%的(de)(de)話其(qi)顏(yan)(yan)色(se)(se)(se)(se)(se)(se)都比(bi)較(jiao)黃(huang)(huang)(huang)(huang)，有的(de)(de)較(jiao)多(duo)是(shi)(shi)H65，H68，H70等，拋(pao)光后其(qi)顏(yan)(yan)色(se)(se)(se)(se)(se)(se)都接近黃(huang)(huang)(huang)(huang)金(jin)色(se)(se)(se)(se)(se)(se)。還(huan)有一(yi)種情況就(jiu)是(shi)(shi)，含(han)銅(tong)(tong)(tong)(tong)量(liang)(liang)盡管不(bu)(bu)高(gao)，但是(shi)(shi)可以通(tong)過化學著(zhu)色(se)(se)(se)(se)(se)(se)的(de)(de)方法來(lai)實現表面達到金(jin)黃(huang)(huang)(huang)(huang)色(se)(se)(se)(se)(se)(se)的(de)(de)目的(de)(de)。

黃銅顏色評定方法：

物質的分子(zi)(zi)內價電子(zi)(zi)的運(yun)(yun)動(dong)是有多個(ge)固定的軌(gui)道的，不(bu)(bu)(bu)同(tong)的軌(gui)道上運(yun)(yun)行的價電子(zi)(zi)的能量不(bu)(bu)(bu)一(yi)(yi)樣，因此價電子(zi)(zi)從一(yi)(yi)個(ge)軌(gui)道躍遷(qian)到另(ling)一(yi)(yi)個(ge)軌(gui)道需要吸(xi)(xi)收或放出不(bu)(bu)(bu)同(tong)的能量，表現為吸(xi)(xi)收或發射不(bu)(bu)(bu)同(tong)波長的波，宏(hong)觀上表現出顏色。同(tong)一(yi)(yi)種元素在不(bu)(bu)(bu)同(tong)價電子(zi)(zi)狀態(tai)下，其(qi)分子(zi)(zi)中價電子(zi)(zi)在躍遷(qian)時需要或放出的能量不(bu)(bu)(bu)同(tong)。

不同光源具有的輻射能量是不樣的，照射在黃銅表面，就會使黃銅呈現出不同的外觀色彩。在冶金行業，為了準確的評定黃銅顏色，就需要統一的光源條件下進行評定。對色燈箱就(jiu)是一種可(ke)以模擬多種標準光源環境(jing)的(de)照(zhao)明燈(deng)箱(xiang)設備，在印(yin)刷(shua)、紡(fang)織、油漆、涂料、五(wu)金等行(xing)業顏色管(guan)理(li)領域有(you)著廣泛應用(yong)。用(yong)戶(hu)按照(zhao)以下步驟就(jiu)可(ke)以輕松檢定黃(huang)銅顏色：

1、連(lian)接對色燈箱電源線(xian)，打開(kai)(kai)電源開(kai)(kai)關

2、切換指定(ding)標準光源，如D65

3、將待測(ce)黃(huang)銅樣品(pin)放(fang)入對色(se)燈箱(xiang)底板中間部位，與(yu)標準(zhun)品(pin)或標準(zhun)色(se)卡進行(xing)對比

 4、觀察(cha)角度(du)(du)以(yi)90度(du)(du)光源(yuan)，45度(du)(du)視線(xian)為宜(yi)，可根據被(bei)測物品(pin)形狀調整(zheng)適當角度(du)(du)，達到檢測最佳效果
