chromeyellow

chromeyellow,是以硝酸鹽如硝酸鉛、鉻酸鹽如重鉻酸鈉為原料,嚴格控制各種反應條件形成穩定的單斜晶形中鉻黃粒子。

chrome yellow主要成分為鉻酸鉛的顏料,其化學組成為PbCrO4,含量約為90%~94%,外觀為淺紅黃色粉末,為單斜晶形,密度為5.1~6.0g/cm3,吸油量為13~27g/100g,抗色滲性極好,遮蓋力居於淺鉻黃深鉻黃之間,明度與淺鉻黃相等,優於深鉻黃,耐酸性與淺鉻黃相等,優於深鉻黃,耐鹼性差,分散性好。
中鉻黃是以硝酸鹽如硝酸鉛、鉻酸鹽如重鉻酸鈉為原料,嚴格控制各種反應條件形成穩定的單斜晶形中鉻黃粒子,經過濾、乾燥、粉碎而成。主要用於塗料,尤其是路標塗料、油墨和塑膠等。Lead chrome yellow,the molecular formula is 25PbCrO4·PbO.The color range is from lemon yellow to orange yellow. It is usually classified 5 standard types as lead chrome yellow,light chrome yellow,medium chrome yellow,deep chrome yellow,chrome orange yellow.The pigments are gloss,bright color shade and excellent hiding power,mainly used for producing coating,paints,inks, plastic, rubber,cultural&educational articles etc.
