Really stone QiChang house hold your identification of emulsioni paint quality

Emulsioni paint directly influences the quality of the coating effect of metope. Before buying emulsioni paint, first of all, to understand the quality appraisal method of emulsioni paint. Next, the division will shaw from the flow flat performance, construction performance, covering power, height of polyvinyl chloride (PVC) identification and washing resistance five aspects to teach you some simple identification method. 1. Flat in the coating performance or small spoon stir evenly coated sticks, and then the small spoon for observing the flow of the coating to the high profile. If coating agglomerate, leveling performance is bad. If a linear pattern, coating coating has a certain flowing performance. Secondly, according to the scale of construction manual will paint which is mixed with water, and bristle brush on the surface of absorption. After drying, coating the surface more smooth, the better the performance of flow flat. two Coating performance of construction according to construction manual dilution proportion of coating, and use the brush to brush in the suction surface. Watch your back The smooth feel, the better the performance of the construction. It should be noted that in some senior paint, manufacturers often add additives to control the thickness of the paint, so that when using the paint on the wall for good fullness. These additives are added to the paint, feel like in the 'brush'. But does this mean that the building performance is not good is a different one. 3. Paint covered the ability to find a clean, old newspapers, fingers in font size and density is thin relatively evenly coated with a layer of paint. After drying, watch the types of ambiguity. The fuzzy type, paint the higher hiding power. This method is more suitable for comparing two different coating. Four. PVC coating grade distinction is refers to the volume of powder content in the coating and the percentage of the latex volume content. In some cases, the lower the polyvinyl chloride (PVC), the mechanical properties of the coating, the better. Are still looking for old newspapers, according to the general coating thickness coated with undiluted coating in the newspaper. After completely dry, slowly folded newspaper, look carefully coating on the surface of the change. When coating surface has a slight crack, stop folding. The record paper roughly folding angles. An internal Angle is smaller, the lower the polyvinyl chloride (PVC), mechanical properties, the better. Second, coating evenly coated on the absorbent basal surface, such as glass. After fully dry, with nails cutting film, observe state of debris. If it is powder form, it shows that the PVC is relatively high. V。 Coating can be washed sex, according to the proportion of construction manual dilution coating and its coating on a solid substrate surface. Normal maintenance for more than a week later, with dark wet towel to wipe gently. Before there was any obvious traces of white on the towel, wipe the more coating can be washed sex, the better. If it is lower level engineering coating need long time to maintain.
