Special applicaions

We can supply phosphorous acid, polyphosphoric acid, and other phosphates and polyphosphate for special applicaions.

Phosphating of metal are provided in order to give anti-corrosion protection for the painting before the base, improve film adhesion layer and anti-corrosion ability and in the metal processing played the role of anti-friction lubrication, corrosion resistant metal material one of the important ways .

Phosphide by end-use can be divided into three categories: 1. Coating, 2. Phosphating, 3. Phosphatizing lubrication of cold extrusion, decorative phosphide.

Phosphatizing phosphate, by classification are: Zinc University, Department of Zinc Calcium, iron-based phosphate, phosphoric acid-manganese grades, phosphoric acid Manganese. According to phosphating temperature classifications are: high temperature (80℃ above) phosphide, medium temperature (50~70℃) phosphide, low temperature phosphating (40℃ or so) and the ambient temperature phosphating (10~30℃). Phosphate on the coatings industry in the paint can be used to produce potassium tripolyphosphate, tripolyphosphate epoxy paint for aluminum and zinc.

Potassium tripolyphosphate with super-strong metal ions on the dispersion ability, excellent complexing capacity and stable pH buffer capability, can significantly improve the performance of paint coatings.

Aluminum Tripolyphosphate of tripolyphosphate ion (P3O5-10) of the trivalent iron ion has a strong complexing ability to react with the iron anode can be formed to iron phosphate-based trimeric complex protective film . This dense membranes do not dissolve in water purification, high hardness, excellent adhesion, showing a superior anti-corrosion performance. Because of (P3O5-10) gene has a very good activity, with a lot of metal ions to form complex, has a good anti-corrosion effect.

Aluminum Tripolyphosphate unleaded, chromium and other precious metals to the non-toxic, non-polluting, non-stimulating effect on the skin, thermal stability, rust-proof ability, in the paint with small, low-cost units. Aluminum Tripolyphosphate used swap paint has excellent anti-rust properties and water resistance for a variety of lacquer-based paint for the preparation of a variety of water-resistant, acid-resistant, anti-corrosion coatings such as phenolic paint, epoxy paint, C Chatham acid paint, as well as water-soluble tree ambition and so on, are widely used in ships, automobiles, industrial machinery, light metal, household appliances and food, etc. with a metal anti-rust ball.

Zinc anti-corrosion epoxy paints performance, good mechanical properties, adhesion, and has electrical conductivity and cathodic protection role, can be used as a workshop Precoating primer does not affect welding performance can also be used as anti-rust primer. It is mainly used for bridges, ships, offshore oil drilling platforms, harbor facilities and all of the substrate after blasting.
