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