我公司目前拥有两条全自动达克罗加工线，一条常州君合科技有限公司，一条常州高克锈机械有限公司的达克罗涂覆加工线。
涂料用的是美加力 (MAGNI CHINA）和安美特。
只有拥有*好的涂覆设备和*优秀的达克罗漆，才能做出高品质产品。
公司主要业务有达克罗，无铬达克罗，锌铝涂层业务等。
我公司坐落于上海市宝山开发区，交通便利。
公司已通过ISO9001-2008，TS16949质量体系认证。
客户有三一重工，中联重科，金风科技，湘电，晋亿实业，隧道股份，上海地铁上海球明的汽车内饰标准件（如螺母夹、卡扣等），开天传动（上海）的风电设备等
上海三环的弹簧等，上海新兴车灯的遮光板等知名企业。
在钢铁上的达克罗膜层厚度*常用的测定方法一般是采用光电测厚器，和显微镜法。
用指甲划可以大概检查出达克罗膜层的厚度，被划过的地方有白色的划痕出现。
假如划痕粗大，说明达克罗膜层疏松厚，划痕细腻说明达克罗膜层薄细腻。
如果没划痕，说明膜层很薄很细腻。
有些客户要求达克罗的膜层厚度控制在某方位以内，方便于以后的装配。
而有些达克罗要求越厚越好，才能发挥*佳的作用。
达克罗的前处理是影响达克罗膜层的*要原因之一。
上海达克罗的盐雾时间一般在48-2000小时，可根据客户的要求来设计工艺路线。
一般来讲，所要求的盐雾时间要求越高，厚度越厚。
在同等的盐雾要求下，厚度越薄越好。盐雾试验是以国家规定的盐雾测试标准测试。
盐雾试验的检测有三种方法，氯化钠腐蚀法，按照GB6817-96标准。
将做好的达克罗产品，在干燥的室内放置48小时，后浸入百分之三的氯化钠水溶剂。
上海达克罗加工在规定的时间取出，目视检查，试样表面不应有出现锈蚀。
硫酸铜点滴法，按照GB5936-86标准。
将硫酸铜溶剂点滴在处理好的试样上，观察红色腐蚀点的时间。
In the iron and steel in dacro membrane layer thickness is the most commonly used measuring method
is generally adopts photoelectric thickness detector, and microscopy. With his nails stroke can
probably check out the dacro membrane layer thickness, be across the place where white lines appear. If Nick bulky, explain dacro film loose thick, scratch exquisite description dacro membrane layerthin delicate. If you don't scratch that film layer is very thin is very delicate.Some customer requirement of dacromet film thickness control in a certain azimuth of less than, convenient in later assembly. And some dacro requirements yue houyue good, can play the role of the best. Before of dacromet treatment is influence dacro film of the most to one of the reasons why. Shanghai dacro of salt fog time generally in 48-2000 hours, may according to the customer request to design process route. Generally speaking, the requirements of the salt fog time request is higher, the thickness of the thick. In the same salt fog request, under the thin thickness, the better. Salt spray test based on the provisions of the state of salt fog test standard test. Salt spray test detection there are three kinds of method, sodium chloride corrosion method, according to the GB6817-96 standard. Will do well dacro products, in dry indoor for 48 hours, after dip three percent sodium chloride water solvent. In the stipulation time out, visual inspection, sample surface corrosion should not appear. Copper sulfate drop method, according to the GB5936-86 standard. Will copper sulfate solvent drop in dealing with good sample, observation red corrosion point of time. |
