High-tech enterprises through the ISO9001 quality system certification
The temperature bonderite of WX-988-5-type steel pieces
First, use
Product manganese phosphating, spare parts for cars, motorcycles, boats and high-speed operation antifriction self-lubrig function of film processing, as well as tools, knives, and require a higheandard parts wear-resistant, corrosion-resistant film processing .
Second, the characteristics
This product generated phosphating film is delicate, the grain was hemispherical, lubricity, anti-corrosion ability.
Third, technical indicators
Color appe磷化液arance state pH value of the proportion of mechanical impurities processing area (m2/kg)
Red ~ 0.02% 10 ± 0.1% < 0.02 ± 1 1.420 <and yellow transparent liquid 15
Fourth, the process description
Use this product with water diluted 1:10 苏州磷化液(volume ratio), add water as the working C can be used, the phosphide time 15 minutes.° 98 ~fluid, Stir heat常州磷化液ed to 95 New with the working fluid to go through the trial phosphide qualified before mass production.
1. Test: Take a working solution 5 ml in 250 ml Erlenmeyer flask, 50 ml of distilled water, 上海磷化液drop 2 drops of methyl orange indicator, titrate with 0.1N sodium hydroxide to the orange and yellow is the end, consumed 0.1 N 5 drops of phenolphthalein~sodium hydroxide mill南京磷化液iliters x 2 Fa; then drops 4 indicator to appear red is t无锡磷化液he end, continue to titrate with 0.1N sodium hydroxide, 0.1N sodium hydroxide consumed total by 2 milliliters Ta.
2. The ~ 70, the acid ratio (Ta / Fa): 6 ~ 1上海磷化加工0, Ta: 60 ~best working condition: FA: 6 9.
Operating 20 minutes.~ C, processing time: 15 ° 98 ~Temperature: 95
3. Adjustment: 9, the addition 上海锰磷化of sodium> 55 additional concentrate; Fa < 6 or Ta <When Fa carbonate per liter of working solution and 0.5 g of sodium carbonate, Fa reduce 70 add上海达克罗加工itional water;>1 Ta point.
4. Note supplemental the tank evaporate moisture; regular cleaning of the tank bottom sediments.
