我公司目前擁有兩條全自動達克羅加工線,一條常州君合科技有限公司,一條常州高克銹機械有限公司的達克羅涂覆加工線。
涂料用的是美加力 (MAGNI CHINA)和安美特。
只有擁有*好的涂覆設備和*優秀的達克羅漆,才能做出高品質產品。
公司主要業務有達克羅,無鉻達克羅,鋅鋁涂層業務等。
我公司坐落于上海市寶山開發區,交通便利。
公司已通過ISO9001-2008,TS16949質量體系認證。
客戶有三一重工,中聯重科,金風科技,湘電,晉億實業,隧道股份,上海地鐵上海球明的汽車內飾標準件(如螺母夾、卡扣等),開天傳動(上海)的風電設備等
上海三環的彈簧等,上海新興車燈的遮光板等知名企業。
在鋼鐵上的達克羅膜層厚度*常用的測定方法一般是采用光電測厚器,和顯微鏡法。
用指甲劃可以大概檢查出達克羅膜層的厚度,被劃過的地方有白色的劃痕出現。
假如劃痕粗大,說明達克羅膜層疏松厚,劃痕細膩說明達克羅膜層薄細膩。
如果沒劃痕,說明膜層很薄很細膩。
有些客戶要求達克羅的膜層厚度控制在某方位以內,方便于以后的裝配。
而有些達克羅要求越厚越好,才能發揮*佳的作用。
達克羅的前處理是影響達克羅膜層的*要原因之一。
上海達克羅的鹽霧時間一般在48-2000小時,可根據客戶的要求來設計工藝路線。
一般來講,所要求的鹽霧時間要求越高,厚度越厚。
在同等的鹽霧要求下,厚度越薄越好。鹽霧試驗是以國家規定的鹽霧測試標準測試。
鹽霧試驗的檢測有三種方法,氯化鈉腐蝕法,按照GB6817-96標準。
將做好的達克羅產品,在干燥的室內放置48小時,后浸入百分之三的氯化鈉水溶劑。
上海達克羅加工在規定的時間取出,目視檢查,試樣表面不應有出現銹蝕。
硫酸銅點滴法,按照GB5936-86標準。
將硫酸銅溶劑點滴在處理好的試樣上,觀察紅色腐蝕點的時間。
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. |
