The single most important function that can influence coating performance is the quality of surface preparation. For optimum service life, the surface must be completely free of all contaminants that might impair performance and should be treated as such to assure good and permanent adhesion of the coating system. The quality of surface preparation has a direct relation with the system lifetime. Even when using the best tolerant coating it cannot be emphasized enough that better surface preparation always result in longer lifetime.
Thainam provide a fully surface preparation solution that meet your specific requirement consist Mechanical tools cleaning, Abrasive blasting, and High pressure water jetting.
Mechanical tools cleaning
Examples of Mechanical tools are rotary wire brushes, sanding disc, and needle guns. Mechanical tools are more effective and less laborious than hand tool such as brushes, sand paper… However, Mechanical tools cleaning will not remove tightly adhering rust and mill scale. This method is usually used in confined working space, where Abrasive blasting and Water jetting are not proper.
Abrasive blasting is based on the principle of an abrasive jet of particles in a compressed air stream impinging on the surface, removing impurities, mill scale, rust, and old coating. Abrasive cleaning is the most thorough and widely use method of surface preparation in the ship building and repair industry.
Beside hand blasting equipment, Thainam did not hesitate to apply latest technology by owning automatic and semi-automatic abrasive blasting device including vacuum waste retriever function. This technology save cleaning cost by recycling abrasive as well as prevent the spread of dust to the environment.
High pressure water jetting
High pressure water jetting is a technique for cleaning surfaces, which relies entirely on the energy of water striking a surface to achieve its cleaning effect. Abrasives are NOT used in high pressure water jetting systems. Consequently, the problems caused by dust pollution and by the disposal of spent abrasives are eliminated. Especially for non-sparkle relative program such as in chemical plant, refinery, and other inflammable area, high pressure water jetting is always the optimum solution.
As the leader in industrial cleaning by high pressure water jet, we are capable to offer the best surface preparation service in Vietnam market.
Following is the surface quality based on international ISO-8501-1:
