    Core tip: waterborne industrial coating is the latest coating in the market In the home decoration, it is inevitable to use water-based industrial coatings, so what is the water-based industrial coatings? Do you know about the water-based industrial coatings? Maybe many people do not have a special understanding, because there is less contact in ordinary life, so how about the water-based industrial coatings? What are the advantages and disadvantages? The following decoration network will be introduced in detail for you There are many advantages and disadvantages of water-based industrial coatings: 1 What are the advantages of water-based industrial coatings? 1 Water-based coatings use water as solvent to save a lot of resources; water-based coatings eliminate fire during construction Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings: waterborne industrial coatings are the latest coatings on the market In the home decoration, it is inevitable to use water-based industrial coatings, so what is the water-based industrial coatings? Do you know about the water-based industrial coatings? Maybe many people do not have a special understanding, because there is less contact in ordinary life, so how about the water-based industrial coatings? What are the advantages and disadvantages? The following decoration network will be introduced in detail for you There are many advantages and disadvantages of water-based industrial coatings: 1 What are the advantages of water-based industrial coatings? 1 Water-based coatings use water as solvent to save a lot of resources; water-based coatings eliminate the risk of fire during construction; reduce air pollution; water-based coatings only use a small amount of low toxic alcohol ether organic solvents to improve the working environment The organic solvent of general water-based coating is between 10% and 15%, while the current cathodic electrophoretic coating has dropped below 1.2%, which has a significant effect on reducing pollution and saving resources 2; The water-based coating has good adaptability to the material surface and strong coating adhesion 3 The water-based coating tools can be cleaned with water, greatly reducing the consumption of cleaning solvent 4 The electrophoretic coating of the water-based coating is even and flat The inner cavity, welding seam, edge and edge can be coated with a certain thickness of coating, which has a good protection; The electrophoretic coating has the best corrosion resistance, and the salt spray resistance of thick film cathodic electrophoretic coating can reach up to 1200h 2 What are the disadvantages of water-based industrial coating? 1 The water-based coating has high requirements on the construction process and material surface cleanliness Because of the high surface tension of water, the dirt is easy to produce shrinkage holes in the coating 2 The water-based coating is resistant to strong machinery The dispersion stability of the force is poor When the velocity in the pipeline changes rapidly, the dispersed particles are compressed into solid particles, making the coating produce pockmarks The shape of the pipeline is required to be good, and the pipe wall is free of defects 3 The water-based coating is corrosive to the coating equipment, which requires the use of anti-corrosion lining or stainless steel materials, and the equipment cost is high The corrosion and metal dissolution of water-based coating to the transmission pipeline make the dispersed particles separate out and the coating film produce pockmarks Stainless steel pipe is also needed 4 The baking type water-based coating has strict requirements on the construction environment (temperature and humidity), which increases the input of temperature and humidity regulating equipment, and also increases the energy consumption 5 The evaporation latent heat of water-based coating water is large, and the baking energy consumption is large The cathodic electrophoretic coating needs to be baked at 180 ℃, while the latex coating has a long time to dry completely 6 The organic cosolvent with high boiling point of the water-based coating produces a lot of oil smoke when baking, which drips on the surface of the coating film after condensation and affects the appearance 7 The water-based coating has the problem of poor water resistance, which makes the stability of the coating material and bath liquid poor, and the water resistance of the coating film poor The medium of waterborne coatings is generally slightly alkaline (ph7.5 ~ ph8.5) The ester bond in the resin is easy to hydrolyze and degrade the molecular chain, which affects the stability of coatings and bath solution, as well as the performance of the coating film The above is an introduction to the advantages and disadvantages of waterborne industrial coatings I believe that many people have a correct understanding of waterborne industrial coatings, and I hope to help you Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
