Development trend of heavy anti-corrosion coatings for offshore platform
Development trend of heavy anti-corrosion coatings for offshore platform mainly has the following three directions: Long-term nature: the coating has strong corrosion resistance and high mechanical strength, can guarantee a long time maintenance-free coating system; Pollution: in the design and development process to ensure that the paint itself part of (film-forming material, anticorrosive pigments, solvents and additives), low-pollution paint paint production process, painting process as a whole. Construction is simple: once the film is thick, strong adhesion strength of coatings.
Development model of heavy anti-corrosion coatings for Marine platform
Our country’s offshore oil industry started late, Offshore heavy anti-corrosion coatings with foreign advanced level compared to a big gap, which requires workers to learn from experience in other countries to develop anti-corrosion, hard work, and catch up. Current marine heavy anti-corrosion coatings have a variety of development model: One is the Japanese model: Japan as early as the 1970s began the large project of the Cross Harbour Tunnel, the island between the Bridge and the reclamation Island, in order toRead More …
Marine platform heavy anti-corrosion coatings
Inorganic zinc rich primer is one of the long-term primer, but it is a solvent-based coatings, pollution of the environment. Water-borne inorganic zinc-rich primer and high modulus potassium silicate binder is a proven environmentally friendly high-performance anti-corrosion coatings, if they can improve their physical properties and performance of construction, the strain potential growth. “Thick film” anti-corrosion coatings The thick film “heavy anti-corrosion coating refers to the first film in more than 100μm coating species. In recent years the development ofRead More …
The zinc rich coating is divided into two major categories of organic and inorganic.
Commonly used organic epoxy, chlorinated rubber, vinyl resin and polyurethane resin as binder, the most commonly used epoxy zinc rich coating, in which the polyamide curing zinc rich epoxy primer is organic zinc-rich primer application the largest species. Zinc is the aggregate into the paint as the expense of polar pigments and fillers and resin, fillers, solvents, and to protect the metal substrate surface, but lack the heavy anti-corrosion features to give the metal substrate surface. Therefore, based on theRead More …
Application notes for fissure powder coatings
Electrostatic spraying with ordinary powder spraying techniques, no special requirements. Application is quick and easy, not the problem of coating, a spray can, without increasing the coating process. Can automatically spray gun, the more uniform texture. Gully and concave need to manually fill spray. Powder coating powder construction process should seek to spray to the metal workpiece surface is uniform coating of uniform thickness and suitable. Coating have the following characteristics: Thick coating can be larger uniform fissure effect, clear texture; thinRead More …
Primers based on spherical zinc dust and Micaceous iron oxide
Primers based on spherical zinc dust and Micaceous iron oxide(MIO) The preparation of zinc rich primers was based on a semisolid epoxy resin, a polyaminoamide adduct-like hardener, spherical zinc dust and the MIO. Paints were formulated with a pigment volume concentration (PVC) from 40 to 65%; the volume ratio of zinc dust and MIO was 1:1. The partial replacement of spherical zinc dust by MIO was examined with PVC = 65%; the ratio between spherical zinc dust and MIO wasRead More …
