颜料物性试验方法

2017年10月18日 admin 0
颜料物性试验方法 Method of testing the Property of Pigments
1.耐光性试验  Teshing of Light Fastness
取各色别之试片裁剪成适当之长宽，放置于Fade-O-Meter中照射，区分3-400小时取出，其结果对照
 Blue Scale 1-To-8标准色卡之级数判定耐光程度优劣，8级（不变色），1级***差（严重变色）。
Cutting various pieces of color pattern sheets to suitable sizes,then put them into the Fade-
O-Meter for light exposure,and to divide the time of exposure to be in the range of 3-400 ho-
urs. Afterward,take out the test pattern sheets to assess their degrees of color fading and dis-
coloration against a standard Blue Scale which is assigned to value form 1 to 8. Grade 8 is the 
excellent(color will not be changed),grade 1 is very poor (color is shanged severly).

2.耐热性试验  Testing of Heat Resistance
取各色别之试片裁剪成适当之长宽，8块放置于烘箱中，以180±2℃每隔10分钟取出1块，至8块取完
为止，作老化试验，观察其变色（褪色）程度。5级（不变色），1级***差（严重变色）。
Cutting various pieces of color pattern sheets to suitable sizes,Take 8 pieces and put them into
an oven under a condition of 180±2℃ for testing.Take out each piece every 10 minute,and to
inspect their degree of color changing (degree of color fading).Grade 5 is the excellent and
grade 1 is the worst.

3.耐酸碱性试验  Testing for Acids or Alkalis Resistance
去各色别之试片裁剪成适当之长宽，将试片浸泡于5%盐酸或10%氢氧化钠中，24小时后取出，观察
其变色程度，5级（不变色），1级***差（严重变色）。
Cutting various pieces of color pattern sheets to suitable sizes,Take desired piece dip in into
the bath of 5% HCl or 10% NaOH for 24 hours,then take them out to assess their degree of
color fading. On a comparison scale,Grade 5 is the excell ent and grade 1 is the worst.

颜料物性检验分级  Scale for Assessment of Physical Property of Pigment
1.耐光性Light Fastness
耐光性坚牢度分为8级，8级代表耐光性（不变色），1级代表耐光性***差（严重变色）。
Light Fastness is assessed on 1 to 8 grade,grade 8 is the Exellent,grade 1 is very poor.
