Coating technology: application of HR new wear-resistant and anticorrosive coating

Core tip: HR heavy-duty anti-corrosion and wear-resistant coating is a two-component coating which can be solidified at room temperature with epoxy resin as film-forming material and ceramic powder as wear-resistant filler The coating has the characteristics of wear resistance, excellent corrosion resistance, high comprehensive physical and mechanical properties, and convenient construction The corrosion of petroleum metal pipeline has brought huge losses to the construction of petrochemical industry The petrochemical industry invests huge funds for the corrosion prevention of metal pipeline every year The internal corrosion prevention of pipeline has always been an important work in the production and construction of petrochemical industry At present, the internal corrosion prevention of domestic pipeline mainly includes stainless steel lining, epoxy powder, nano titanium and other technologies HR new wear resistance 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 Coating House News: HR heavy-duty anti-corrosion, wear-resistant and anti-corrosion coating is a two-component coating with epoxy resin as film-forming material and ceramic

anti-corrosion coating is developed in cooperation with Hai Rui petroleum, which is mainly applied to all kinds of new anti-corrosion coatings for pipeline internal corrosion It solves the phenomenon of lining falling off in the use of stainless steel internal lining pipe, and fills the technical gap of using ceramic coating for pipeline internal corrosion protection in China The main mechanism of HR wear-resistant ceramic anti-corrosion coating is that HR wear-resistant ceramic anti-corrosion coating uses submicron ceramic particles as fillers, which is a kind of wear-resistant anti-corrosion coating that can protect the surface of most metal pipes It is divided into two parts: A and B Component A is a mixture of ceramic powder, epoxy resin and volatile organic compounds, and component B is a curing agent When the prepared HR wear-resistant and anti-corrosion coating is sprayed on the surface of the workpiece after surface pretreatment by high-pressure air spraying equipment, the coating will gradually solidify at room temperature, and then bond with the substrate to form a ceramic coating with the advantages of high hardness, wear resistance, corrosion resistance, high-temperature oxidation resistance, etc The coating can be sprayed, brushed or rolled at room temperature, and the operation is very simple The coating can be used on the pipe wall of oil and gas wells containing a large number of chemical substances such as CO2, H2S and brine, which can greatly improve the service life of the pipeline HR wear-resistant ceramic anti-corrosion coating is a two-component high wear-resistant ceramic anti-corrosion coating based on epoxy resin and wear-resistant pigments such as flexible ceramic powder The main ceramic components are a, B and C (a, B, C -- Code of specific kinds of ceramic powder) component a of ceramic is a white loose crystalline powder, the average size of powder particles is 40-70 μ m, each particle is composed of many small crystals with particle size less than 0.1 μ m, which is a porous spherical focus, and each particle can contain multiple small crystals The porosity in the particles is 25% ~ 30% of the total volume, which is not conducive to the contact of a crystal The microstructure of a-ceramic composite with a certain number of B components has changed greatly, the crystal size of the composite material has decreased significantly, and the abnormal growth of the main crystal of a-ceramic has been overcome The fracture mode is the coexistence of transgranular and intergranular fracture In addition to the distribution between the grain boundaries of the main crystal phase, some nanoparticles are distributed on the transgranular fracture surface of the main crystal phase B has low expansion coefficient, high hardness and high thermal conductivity Adding a can improve the thermal shock resistance and toughness of ceramics HR wear-resistant ceramic anticorrosive coating has dense film, good impermeability and excellent protective performance under severe conditions It can be used for a long time in oilfield sewage, acid, alkali, salt and other corrosive media The coating has been preliminarily inspected by Qingdao marine chemical coatings research institute to reach the qualified standard and the marine inspection standard Home of coatings is specialized in coatings, diatom
