发布时间:2015-12-5 9:54:16 浏览次数:646

   喷砂完成后首先应对喷砂除锈部位进行全面检查,其次要对基体钢材表面清洁度和你进行检查。重点检查不一定容易喷气部位手工或动力工具除锈部上可适当降低要求。基体钢材表面的清洁度和你进行检查时,严禁用手抚摸;第二반드点好晒或散射照度相当的人工照明条件下进行,以免漏检。


    喷砂除锈后,金属结构表面清洁度。Sa 21 / 2对照了。《涂装前钢材表面锈除锈等级,等级》中提供的照片进行比较,比较的时候2m2至少每一点。


    喷砂除锈后,金属结构表面润饰。Ry 60~100 m的原因,根据技术要求,必须按取血,市模范,至少7倍放大镜放大后比较时2m2至少每一点血。速度计直接测定时,每2m2表面至少指定长度的评定。40mm长度范围为我方5点,寻找那个算术平均评估指定的值。서피斯市。



Sandblasting after completion of first response to sandblast and rust removing parts of a comprehensive inspection, next to the steel matrix surface cleanliness and you are examined. Focus on examination is not necessarily easy to jet parts by hand or power tool cleaning part may be appropriate to reduce the requirements. Matrix steel surface cleanliness and you are examined, it is strictly prohibited to touch; the second point bask or scattering intensity is quite artificial lighting conditions, in order to avoid detection.


After blasting, the metal structure surface cleanliness. Sa 21 / 2. "Before coating steel surface rust rust grades and grade, in the photos were compared, the comparison when 2M2 at least every point.


After blasting, the surface of polished metal structure. Ry 60 ~ 100 m reasons, according to the technical requirements, must be taken blood, city model, at least 7 times the magnifying glass after amplification 2M2 at least every point of blood. At least a specified length of time per 2M2 surface is measured at a speed meter. 40mm length range is 5 points, and the arithmetic mean value is evaluated. Adams city.
