摘要
铝型材表面条状印迹一般分为擦划伤印、皮带印、隔条印、水印、铬化印等,直接喷粉或喷漆,涂层无法彻底遮盖,导致产品表面质量不良,追溯导致以上印迹的原因并进行分类,通过更换冷床破损皮带、调整前处理工艺、提高烘烤温度、延长烘烤时间以及优化隔条等方法,彻底解决了批量印迹造成的返工报废,改善了产品表面质量,节约了生产成本,供同行参考借鉴.
Abstract
The strip imprints on aluminium profile surface are generally divided into scratch imprint,belt imprint,spacer imprint,wa-termark,chrome imprint,etc.Direct powder spraying or spray painting cannot completely cover the coating,resulting in poor surface quality of the product.The reasons for the above imprints were traced and classified,and methods such as replacing the damaged belt of the cooling bed,adjusting the pre-treatment process,increasing the baking temperature,extending the baking time,and optimizing the spacer strip were used,which thoroughly solved the rework scrap caused by batch imprinting,improved the product surface quali-ty,saved production costs,and provided reference for peers.
