Would you please mail us some sample materials 请给我们寄一些样料。
How much sample material is required ? can it be reused 需要多少样品量?样品用完之后能再用吗?
Standard specification for wipe sampling materials for lead in surface dust 表层粉尘中铅含量测定用擦拭取样物标准规范
The thermal conductivity decides the processing parameters choosing for a material , such as a sample material with low thermal conductivity need low rotate speed and high friction pressure 材料热物理性能决定了热诱导试验的参数选择,对于导热性差的材料应选用低转速和大压力。
