测试原理:
使大量小的、带有锋利边缘的钢丸或碎石在短时间内撞击层表面,整个试验在可控温度下进行。石击结束后,用胶带去除松散涂层,露出样板上残留的石击点痕迹,通过分析涂层的破坏程度判断其抗石击性能的优劣。
目前,国内外有以下两大体系的涂层抗石击性试验及评价方法被广泛应用。
*
标准化组织(ISO)制订的ISO 20567-1《色漆和清漆 涂层的耐石性的测定 第1部分:多次冲击试验》来源于德国工业标准DIN 55996-1:2001《涂层材料的碎石冲击强度检验第1部分:多重冲击试验》,所以在欧洲,德国标准化协会、法国标准化协会和奥地利标准化协会等均引用此标准建立了自己本国的检测标准。
例如,德国汽车公司采用的标准为DIN EN ISO 20567-1《色漆和清漆 涂层的耐石击性的测定第1部分:多次冲击试验》,设备为德国Erichsen公司的508型多功能抗石击仪。
SAE体系
美国汽车工程师协会(SAE)制定的SAE J400《汽车表面涂层的抗碎石测试》多被美国的通用和福特等汽车公司采用。
日系汽车公司采用的抗石击方法大体温表与SAE J400《汽车表面涂层的抗碎石测试》相似,但在碎石的规格、试验温度和评价方法等方面又有所不同。因我国有较多的与日本汽车公司合资的企业,所以JIS的射石法也比较常见。
