Paint knowledge | application rate of inorganic zinc rich primer

It is suggested that inorganic zinc rich primer takes inorganic polymer (such as silicate, phosphate, dichromate, etc.) as film-forming material, with which zinc powder reacts to form zinc iron complex on the metal surface, forming a solid protective film Inorganic zinc rich paint is mainly divided into water-based inorganic zinc rich paint and alcohol soluble inorganic zinc rich paint The paint is a two-component packaging product composed of alkali metal silicate as component one, zinc powder and pigment as component two The color of inorganic zinc rich primer this paint has excellent anti-corrosion effect, with water as the solvent, no fire hazard, can withstand 400 ℃ high temperature, excellent resistance to crude oil and solvent The paint can be used in oil tank, oil tank, solvent tank, ballast tank and environment Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings: inorganic zinc rich primer is based on inorganic polymer (such as silicate, phosphate, dichromate, etc.) as the film-forming material, with which zinc powder reacts, forming a zinc iron complex on the metal surface, forming a solid protective coating Inorganic zinc rich paint is mainly divided into water-based inorganic zinc rich paint and alcohol soluble inorganic zinc rich paint The paint is a two-component packaging product composed of alkali metal silicate as component one, zinc powder and pigment as component two The color of inorganic zinc rich primer this paint has excellent anti-corrosion effect, with water as the solvent, no fire hazard, can withstand 400 ℃ high temperature, excellent resistance to crude oil and solvent The paint can be used for oil tank, oil tank, solvent tank, ballast water tank, marine steel structure, bridge, chimney, etc with harsh environment and conditions It can also be used as antirust and heat-resistant coating The color and appearance of the paint film are reddish gray to dark gray, the color is insufficient, and the paint film is flat Properties of inorganic zinc rich primer inorganic zinc rich primer has electrochemical protection because it is rich in zinc powder The hardness of the paint film is higher than Hb, not only that, but also the adhesion of inorganic zinc rich primer is very high The result measured by steel ring method is less than 2, which has good mechanical properties The drying time of inorganic zinc rich primer is also very fast At 25 ℃, the surface drying time is less than 5min, and the actual drying time is less than 12h It only needs a very short time to transport, stack and paint the second coat The impact strength of inorganic zinc rich primer is 50kg, which has excellent impact resistance and wear resistance, but its flexibility is only moderate, it can match most paints In addition, the test also shows that the bending degree of the inorganic zinc rich primer is less than 1 mm, and its welding burn width is less than 15 mm Coating rate of inorganic zinc rich primer coating rate of inorganic zinc rich primer is actually a measurement parameter of the use of this kind of paint This is often a theoretical value, but not for practical application Because we say that the actual situation is relatively complex, including all kinds of waste, as well as improper use of coating equipment and so on In this way, there is a certain deviation between the theoretical coating rate and the actual coating rate of inorganic zinc rich primer Theoretical value of the coating rate of inorganic zinc rich primer: 1kg or 1L of inorganic zinc rich primer, among the specified film thickness, the largest area that can be coated is the theoretical coating rate Its relevant calculation method is: (1000 * Volume solids) / (specific gravity * dry film thickness) Inorganic zinc rich primer price solvent based inorganic zinc rich primer, paint is inorganic zinc rich But dilute with alcohol soluble diluent Prices generally range from 35-40 Inorganic zinc rich primer construction 1 Before the construction, the construction personnel must strictly check and repair the loophole area to be repaired, generally using the methods of air hole, undercut, free edge quick opening, etc on the weld, the electric welding and other initiating operations in other adjacent areas must be completed to ensure the integrity of primer 2 Prepare the surface and sand to Sa2.5 The surface roughness shall be within the range of 40-75 μ M all shop primers shall be removed Taking the hull as an example, it is better to complete the sand washing of class A at one time If the conditions are not allowed, the shipyard shall discuss and arrange the best sand washing sequence to prevent the conflict between sand washing and painting from delaying the construction period Before sand flushing, the construction personnel need to deal with the dead angle and the complex structure parts first, so as to avoid the delay of construction period due to the failure of the parts to meet the repair conditions during the repair Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire
