Supply auspicious brand XH-11F combo color film phosphating solution

Harmony brand XH-11F-type room temperature skim Color Phosphating combo of treatment agent 1 Scope This product is used under normal temperature conditions, degreasing and phosphating completed, can be used for steel furniture, doors, windows, shelves, lamps, oil drums before phosphating processing products such as paint, spray, paint, painting process supporting. 2 Features 2.1 simple process. Skim, phosphating step completed after phosphating without washing or washing can be phosphating process does not add accelerator alone. 2.2 high processing quality. Degreasing ability, speed, phosphate coating for fine crystal, uniform, non-hanging gray, rust resistance. 2.3 pollution is minimal. Excluding NaNO2 NaF and Cr6 + and other harmful substances, good stability and sediment little, simply add the concentrate can be used for a period of time, infrequent emissions, no smell, no harmful gases, good working conditions. 2.4 less investment in equipment. The production line is short, less area, does not require a dedicated waste management equipment. 2.5 use and low cost. Can be significant savings in site fees, labor costs, heating costs, equipment costs, and other expenses of solution consumed. 3 major technical indicators No Item Index Concentrate Appearance colorless to milky white liquid concentrate total acidity (dot) 310 to 360 ratio (%) 10 liquid liquid 3 to 8 working fluid total acidity, free acidity (point) (point) 10 to 50 phosphating time (min) immersion of the working solution pH of 22 to 28 the phosphating temperature (° C) of the value of 2 to 3: 10 to 20, sprayed: 3 ~ 6 phosphating manner impregnated spray 4 process no rust workpiece → degreasing phosphating combo treatment → rinsing → passivation → dry dry dry 5 preparation and maintenance 5.1 formulated bath to join the 1/2 water, then added an XH-11F type phosphating solution, stir to complement the water through the ISO9001 international quality management system certification ISO14001 international environmental management system certification coating, harmony before processing begins! Stir and stand for 30 minutes before use. 5.2 Detection 5.2.1 Total acidity (TA): Take the phosphating bath 10 mL of plus 50mL distilled water, using phenolphthalein as an indicator, when the solution becomes pink endpoint titration 0.1mol / L standard NaOH solution, the consumption NaOH standard solution used in ml is the total acidity, expressed with a "point". 5.2.2 free acidity (FA): Take the phosphating bath 10 mL of plus 50mL distilled water, using bromophenol blue as indicator, 0.1mol / L standard NaOH solution was titrated to the solution from light yellow when the mere mention of blue-purple as the end point, The number of milliliters of the consumed NaOH standard solution to a free acidity, expressed the number of "points". The 5.3 bath supplemented 5.3.1 When the phosphating solution used to a certain extent, the need to fill plus this powder, the method is first to concentrated need additional quantity of the liquid is calculated by the following formula, and then calculated by the concentrated solution of the powder amount. Additional phosphide powder formulated into a concentrated liquid. V conc = C0-C1 × V1 C2-C0 V concentrated: the required volume of concentrated liquid amount of additional; C1: actual total acidity of the bath; C2: concentrate, total acidity; C0: bath requires total acidity ; V1: bath volume. 5.3.2 Simple calculation: 1m3 bath, additional 4kg of concentrate can increase the total acidity of about 1:00. 5.4 after phosphating workpieces, preferably vertically. Phosphide after washing, phosphating time should be extended. 5.5 in the use of the process, if too much foam, add the ratio of 0.05 to 0.1% according to the W-W101 type bubble-free non-silicone surfactants. 6 storage 25kg plastic drum packaging, stored in a cool, well-ventilated place, pay attention to prevent breakage leakage, and alkaline substances isolated storage. 7 Note handling with light-light, to prevent damage splash to the eyes, the preparation or use of the process should wear protective equipment (such as acid-resistant rubber gloves, overalls), such as contact with the skin or eyes, immediately wash with water.
