DH-88 Colloid Titanium Surface Adjuster

1. General introduction

    DH-88 is a colloid titanium salt surface adjuster, which is used for surface adjustment before moderate temperature or low temperature parkerizing. It can bring about a fast parkerizing process and a more refined, solid and even parkerizing film. The coating may be given a richer luster. The erosion-resistance and paint-attachment may also be much improved.

2. Technical norms

   Appearance: white solid powder               Density of the solution to be used: 0.2-0.4%

   Treatment ways: pickling or spraying           Maxium amount of treatment: 1000m2/kg

   Controlling parameters

      General alkalinity --- 2.0-5.0pt             PH value --- 8-9.5

  Time duration for spraying --- >30 seconds   Time duration for pickling --- > 90 seconds

  Material of the tank --- plastic, stainless steel or carbon steel

  Temperature --- normal atmospheric temperature

3. Method of using

a)   Preparing the liquid in the tank:

   Firstly, let the tank contain water up to 80% of the total volume(1000L). The water is required to be of the conductivity 400us/cm.

   Then get the required amount of DH-88 surface adjuster. Let it dissolve in a little water(warm water would be better). Stir well the solution.

   Pour the dissolved surface adjuster into the tank, add water to get to the total volume 1000L. Stir to ensure the liquid well mixed. Test the general alkalinity and put the liquid into use.

b)   Handling the liquid:

   Stir well the liquid in the tank and test the general alkalinity before each day’s operation. Extra  surface adjuster should be supplied according to the test results. But as the liquid is over-used with too much impurity in it, merely putting in extra adjuster will not bring the expected effect --- the parkerizing film will get thinner, murky, with multi-color patterns appearing at places(such film is liable to become yellowish and rusty).  In that case , the dirty, dark liquid must be replaced by a tank of newly prepared liquid. Generally, a 50-ton(or smaller) tank should have its liquid renewed in 7 days. A tank of more than 50 tons, would have its new liquid in 30 days

4. Package and storeage

This product has its 25kg, 30kg, 40kg packages, in lined plastic bags, which are to be kept from moisture and heat. Storage time limit --- 5 years.

5. Points for attention

This product is of a light alkaline character, and users should avoid its coming into contact with their eyes or skin. In case one’s eyes or skin is stained by it, they are to be washed with plenty of water immediately.
