铅膏的相组成与铅粉、硫酸以及温度之间的关系。和制铅青时按程序加人：铅粉、水、硫酸溶液。原则上加水快，加酸慢，酸15min 左右加完，和膏温度控制在30～80 ℃ ，搅拌时间为40-SOmin 。和膏完毕后，要进行工艺上要求的相关检测。在30 ℃ 下进行和裔，硫酸含量＜8 ％时，主要形成3BS 相，3BS 随酸含量增加而增加。IBS 相是酸含量约8 ％时形成，酸含量超过8 ％时形成IBS 。铅青中少量存在斜方晶PbO 。
The lead cream mutually constitutes a relationship with of ceruse, sulfuric acid and temperature.And make a lead green add a person according to the procedure:Ceruse, water and sulfuric acid aqua.Filling with water in principle is quick, add sour slow, the sour 15 min is or so to finish adding, control in 30~80 ℃ with cream temperature, mix blend time is 40-SOmin.Carry on the related examination of the craft top request after completing with cream.Carry on under 30 ℃ and descendant, sulfuric acid content<8%, mainly form a 3 BSs mutually, the 3 BSs increases but increases with the sour content.IBS is mutually a sour content about 8% formation, sour content more than 8% form IBS.The lead is green medium the jot exist inclined square crystal PbO.
