Talking about JD90A Phosphating Cleaning Solution
Hainan Agricultural Reclamation Haikou Agricultural Tools Factory Ding Jinyi
"China Barrel Information" reported the news of the successful development of JD90A phosphating cleaning solution by our factory in the form of a newsletter. As soon as the news came out, it caused the attention of various barrel factories across the country. Some barrel factories in Liaoning, Jiangsu, Guangxi, Fujian, Heilongjiang and other provinces have written letters and letters. Some even come to our factory to understand the situation of phosphating solution and ask to cooperate with our factory to produce this liquid in our factory. Go to the barrel factory everywhere. In order to let more peers understand the situation of the liquid, in order to use the phosphating solution to improve the appearance quality of the steel drum, the phosphating solution is further introduced here. JD90A Phosphating Cleaning Solution is a non-toxic, non-volatile smoke, non-irritating to the skin, and a four-in-one treatment solution for steel surface at the same time as rust removal, degreasing, phosphating and passivation. The liquid reacts with iron or iron oxide to form a stable and dense phosphating passivation film. The liquid has the advantages of strong adhesion of the phosphating film, good corrosion resistance, safe use, no spontaneous combustion, no discharge, and simple operation. It is a steel barrel body, and the bottom cover of the barrel is ideal for "four in one" treatment liquid.
JD90A phosphating cleaning solution can also be used for boiler and pipeline descaling.
JD90A main parameters:
PH value: 1-2
Proportion: 1.08-1.14
Color: creamy yellow
Feel: slippery
Treatment time: light rust for 5 minutes, medium rust for 8 minutes, heavy rust for 15 minutes.
Drying time: ≯ 30 minutes
Processing area per cubic meter of cleaning solution: 6000 square meters
Appearance after treatment: gray black or mouse gray
Phosphating film thickness: ≥7μm
Treatment process: The steel drum is naturally dried by immersion in the phosphating solution at room temperature for 5-1 minutes.
Corrosion resistance:
First, the phosphating film corrosion resistance
1. Dipping method: The test piece was immersed in a 3% aqueous solution of sodium chloride (Na), and kept at 15 to 25 ° C for 1 hour, and the sample was taken out, cleaned, and dried. The surface was visually inspected for substantially no rust.
2. Drip method:
That is, copper sulfate CuS04・5H20, 41g/L
Sodium chloride NaCl, 35g / L
O.1N hydrochloric acid HCl, 13ml/L
When the temperature is 15 ~ 25 ° C, drop the test solution on the surface of the workpiece, and start the stopwatch, the test piece from the sky blue light yellow or light red, time ≥ 60 seconds.
Second, the phosphating paint film corrosion test.
The test piece is coated with white polyurethane paint or asphalt paint. After drying, it is sealed with 1:1 mixture of paraffin and rosin. After standing at room temperature for 24 hours, use the 18# sewing machine needle to cut the paint film into diagonal diagonal lines with the scratches facing up, and then place them in the salt spray test chamber for 8 hours. The paint film has no blistering except for the scratched parts. Shedding, rusting, etc.
Adjustment of liquid medicine: After long-term use, the efficacy of the treatment liquid gradually decreases. When the molar concentration of the solution is compared with the molar concentration of the newly formulated liquid solution of 2.85, the fresh solution should be added when the value is less than 2.5. The dosage was calculated as 1% by weight per Mole of the molar concentration.
False Eyelashes are artificial eyelashes used to beautify the eyes. They are usually lengthened and thickened to make the eyes look bigger, brighter, fuller and more spiritual.False eyelashes have a long history, as early as 2000 BC in ancient Egyptian and Roman literature can be found false eyelashes records.False eyelashes are made of plastic, cotton, feather and other materials. However, with the use of different materials, false eyelashes show different effects (such as exaggerated stage effect).
