Al chemical oxidation chemical oxidation of aluminum sealant liquid HF-642

HF-642 aluminum chemical oxidation of a blocking agent, product applications: HF-642 aluminum oxide blocking agent is a chemical reagent layer for aluminum our normal qualities of aluminum chemical oxidation mildew treatment after closure plugged by this aluminum corrosion resistance can greatly improve after disposal. Typically chemical oxidation corrosion film out, have a certain porosity, the product can effectively be filled to achieve the best corrosion resistance performance, neutral salt spray test piece treated by this product 90 hours ; oxidation mildew treatment is widely used in auto parts, machinery and equipment, electrical accessories, such as aluminum and aluminum alloy surface of the workpiece and the workpiece after processing does not affect the electrical conductivity, corrosion base, does not affect the size of the workpiece. Second, the product advantages: 1, the goods bath preparation easy, convenient operation, simple management; 2, the agent solution is quite stable, can be recycled repeatedly, energy conservation, low overall cost. Third, the operation process: aluminum → washed clean → HF-642 aluminum oxide closed after degreasing chemical decontamination or chemical polishing treatment → washed clean → HF-635 liquid handling qualities of aluminum chemical oxidation or HF-630 aluminum antioxidant treatment agent processing → washed clean → dry four, Instructions: No. Description Usage Notes aluminum chemical oxidation sealant 1 HF-642 5% watered soak 3 2 Use working temperature 90-100 ℃ 4 soaking time of 5-10 304 minutes 5 operating container slot five, management and maintenance: 1, the product powder, a bath concentration by good preparation bath, stir to dissolve after heating to the desired temperature, you can use; 2, available concentration of the pre-treatment ( also known as Bobby meter or meter po Farm) concentration measurement (Be), and record the measurements in the production process, if it can not reach slotted concentration decreased when measured data, the need to supplement HF-642 chemical oxidation of aluminum sealant adjust reached slotted concentration; Reason 3, with the increase in number of processing the workpiece, prolonged use and take bath and other artifacts, the active ingredient and liquid bath decline, this can be The new work was formulated supplement to add in the grooved surface; 4, the product temperature is higher, the operating environment must be ventilated; please wear labor protection operation. VI, packaging and storage: 25 kg / barrel, store in a cool place for 2 years effective.
