It does not give any information on the quantity or size of any pores or uncoated areas, nor any hint onpossible reactions between the aluminium tube and the product. The electrolyte conductivity should never be used as thesole criterion for quality evaluation of the internal coating, but always with other parameters e.g. film thickness, acetoneand/or ammonia resistance and of course results of enhanced stability studies.【中国标准分类号】: A82【国际标准分类号】: 55_120【页数】: 11P.;A4【正文语种】: 英语 | 欢迎光临 世界资料网论坛 (http://bbs.infoeach.com/) | Powered by Discuz!
