Multipurpose phosphorus powdered skim JH-1103 various environmental dipping degreasing metal parts

Suitable for dipping degreasing iron, stainless steel, aluminum, aluminum alloys, aluminum and zinc alloy and other parts of I. Introduction: JH-1103 is an environmentally friendly phosphate-free products for normal cleaning iron, stainless steel, aluminum, aluminum alloys , aluminum and zinc alloy parts, degreasing, suitable for the impregnation process. Second, the bath preparation: three-quarters of the working tank injecting cold water, adding an appropriate amount of chemicals and stirring or circulating well, add enough water to make the liquid level rise to the level of work, and then heated to operating temperature. Third, the control parameters: preparation Concentration: per 1000 liters bath was added 40 to 80 kg JH-1103 type skimmed powder Appearance white powder free alkalinity points 15 to 30 point PH value of the bath temperature at room temperature 13 to 14 ~ 60 ℃ immersion time 3 to 15 minutes four detection methods: the free base with a pipette into the 10 ml milliliter sample into a 250 ml conical beaker, add 2-3 drops of phenolphthalein indicator, titrate with 0.1 N hydrochloric acid solution to a sample pink disappeared, milliliters of 0.1 N hydrochloric acid solution is consumed in the free base points. Total base number with a pipette into the 10 ml milliliter sample into a 250 ml conical beaker, add 2-3 drops of bromophenol green indicator, titrated with 0.1 N sulfuric acid solution into the sample color changes from blue to green and finally disappeared, milliliters of 0.1N hydrochloric acid solution is a total base number of points of consumption. Total alkalinity points are generally used to calculate the ratio of total alkalinity / free alkalinity. V. bath control: for 1000 l bath, each 1 point increase in free alkalinity, need to add two kilograms JH-1103 type defatted flour. Because the cleaning agent to be contaminated, total alkalinity will increase, so that the ratio of total alkalinity and free alkalinity will increase, which provides a method for measuring the degree of contamination of the cleaning agent. The maximum ratio of the total alkalinity / basicity of the free metal species treated with the metal surface of the solid detergent impurity type and operating temperature. Bath regularly discharged, continuous overflow or automatic overflow to keep the ratio of the total alkalinity / free alkalinity does not exceed the maximum rated operating value. VI, storage requirements of this deliquescence should be stored in a cool dry place, such as the process of using crushed find lumps which can be used without affecting the degreasing effect. Seven, eight year shelf life, packaging 25kg kraft paper bags nine waste water treatment should be aware of and follow the provisions on the treatment and disposal of chemicals. Bath is alkaline, it may be required before the washing water or bath or discharged into the sewer and wastewater treatment.
