我公司是专业从事于金属表面处理的高科技企业。
拥有最先进的磷化液生产工艺，保证能为客户提供优质的磷化液产品。
公司在职员工有180多人，我们致力于环保的金属表面处理。
已通过了ISO9001-2008，TS16949质量体系认证。
公司坐落于上海市宝山区，交通便利，能够为客户及时提供优质的产品。
有人说我们磷化液不便宜，其实是我们的磷化液消耗量小，质量好。
我们的黑色锰系磷化液，外观均匀一致，很黑。盐雾时间72小时。
紧固件磷化技术核心：
前处理需要严格要求，因为螺纹里面容易有切削液，机油沉积在里面，甚至有一些灰尘，铁屑等很难清洗的东西，一般的除油剂很难清除彻底。
特别是在冬天更麻烦，首先，用植物油做攻丝油，这样才能更好的清洗掉。然后人工的对盲孔进行清洗，系出里面的油污，残渣。
可以试用高压水进行清洗。再用碱性清洗剂中和。
磷化膜颜色的控制，客户一般对螺丝，螺母颜色，外观要求都很苛刻。
但是，磷化膜颜色根据材质，热处理和游离酸影响比较大。油很重会导致磷化膜不均匀，有花斑产生。
回火的时候才用质量差的产品，磷化膜容易变黑。游离酸越高颜色越深。
所以要想做好磷化加工，就必须控制好游离酸，总酸，酸比。使之控制在最佳范围内，才可以保证磷化膜的颜色。
工作设备：此工作槽体是3吨的槽，可以装2.5吨的磷化液，每框装500根据。
现有两台行车，这样装卸比较方便，省力高效。磷化槽四周铺加热管道，需要一个栅栏套住加热管上面，这样才能保护好加热管不受碰伤，还可以避免沉渣吸附在工件上面。
高速度工具钢的锰系磷化工艺路线有脱脂，水洗，酸洗，水洗，表调，磷化，水洗，热水洗，浸油。
Some people say we phosphating solution is not cheap, and in fact is our phosphating liquid consumption is small, the quality is good.
Our black manganese series phosphating solution, the outward appearance is uniform, very black. Salt fog time 72 hours.
Fasteners phosphating technology core:
Pretreatment need strict request, because the thread it南京磷化液 easy to have cutting fluid, oil deposit inside, and even some dust, iron filings, oxide and it is difficult to clean things, general with the exception of agents is difficult to remove completely. Especially in winter is more trouble, first of all, use vegetable oil do tapping oil, in order to better cleaning off. Then artificial to blind hole cleaning, is out of the inside of the oil pollution, residue. Can try cleaning water cannons. Garnish with alkaline cleaner neutralization.
Phosphate coating color control, customer the general screw, nut color, appearance requirements are very strict. But, phosphating film color according to the material, heat treatment and free acid influence is bigger. Oil is very heavy can lead to phosphate coating uneven, tinea produce. Only when tempering with poor quality products, phosphating film easy to black. Free acid, the higher the darker. So if you want to make phosphate processing, it is necessary to control good free acid, total acid, acid ratio. The control in the best range, can ensure that the color of the phosphating film.
Work equipment: this work tub is 3 tons of tank, can hold 2.5 tons of phosphating solution, each box installed according to 500. The existing two Station Road, so handling more convenient, energy efficient. Phosphating slot spread around the heating pipe, need a fence trapping heating tube above, so as to protect the heating pipe from bruising, still can avoid sediment adsorption in the above.
High speed tool steel of the manganese series phosphating process route have skimmed, water washing, acid, water washing, table to move, phosphating, water, hot water washing, oiled.
