Ten paint coating construction problems and solutions [ 2018 the latest summary]

Paint coating is a sautoir surface engineering, its adornment effect is particularly important, because the paint on the market is becoming more and more and more or less there will be a few small flaws. Today, coburg shaw will summarize the paint and coating of the top ten construction problems and the solutions. 1. What is the stains sealer? The so-called stains sealer is also a kind of primer, is that it is different from ordinary primer has the permeability, can be closed the capillary porosity of concrete. At the same time, the primer is hiding power, can cover the stain on base material. The difference between 2, oil paint and water-based paint and oil paint and water-based paint the difference? Oily coating is the carrier of organic solvents, such as alkyd paint and polyurethane paint. Carrier of the water-based coating is water, for example, common architectural decoration paint latex paint is water-based coating. Oil paint and oil paint on the concept of no difference. Similarly, water-borne coatings and water-borne coatings on the concept of no difference. 3. Why is the glass paint film after drying can harden? The hardness of paint film is associated with the content of the emulsion or associated with the type of emulsion? Under the condition of normal film, the hardness of latex paint film has little to do with the emulsion content, mainly depends on the type of emulsion used. If the glass transition temperature of emulsion used is higher, after normal film hardness of paint film. 4. If you want to paint dry faster, what can you do? For example, you can add the additives? No desiccant emulsioni paint. If you want to dry faster, can increase the volume of solid content, reducing additive formula into membrane and the dosage of the propylene glycol/ethylene glycol. Of course, it is necessary to check other related properties affected by a lot. 5. I want to ask how to melt ( Damage) Epoxy resin, latex and other products, without damage to the workpiece with glue. Made up of strong solvent paint remover can be used to remove paint. 6. Can I book the emulsioni paint is brushed with ceramic tile on old house? Customer plans to decorate the interior wall of the sitting room with ceramic tile, and ceramic tile surface coating latex paint to change the color and appearance. Suggestion: as the ordinary latex paint adhesion on the surface of the ceramic tile, not ideal, the key is before coating latex paint coated with specially designed for ceramic tile emulsioni paint primer. 7. To judge the degree of coverage of titanium dioxide? What method can be used to detect? The covering power of titanium dioxide can be judged by measuring the contrast. How do you determine the contrast, please refer to the gb/T9756 - In 2001 the interior wall paint, synthetic resin emulsion contrast test method. 8. How to detect the emulsion of the glass transition temperature? Emulsion of glass transition temperature measurement is a complex event. Measuring the glass transition temperature changes according to the different test methods. Differential scanning calorimetry meter is to measure the glass transition temperature is the most commonly used instruments. For formula, should pay more attention to the minimum film-forming temperature of latex ( MFFT) , the minimum film-forming temperature by MFFT tester. 9, please use the rohm and haas 3188 emulsion for waterborne coatings, bubble to disappear? In general, when using strong defoaming agent, it is easy to eliminate air bubbles, but there will be shrinkage cavity in the case of poor dispersion. Suggest to switch to BKY - 024 or other defoaming agent, and try to increase the dosage slightly. 10. Why the paint in construction process always blister ( Even if the base is very good) ？ This may be due to defoaming agent selection and use of the existing problems. If the roller structure, the quality of the roller can also cause foaming. Above is xiao summary of some problems in the process of coating decorative solutions. Adornment effect depends largely on the quality of materials, insurable materials, everyone can be trusted.
