Quality standard of interior wall emulsii paint cannot know five big standards
(Summary description)The ratio is set for white and light color paint test items, it can reflect the ability of white and light color paint to eliminate the color or color difference on the substrate, can also indirectly reflect the amount of coating covering the same area of the substrate. The opposite ratio of coating is lower, the ability of product cover bottom material is poorer, coating effect is poorer, amount of unit area coating is bigger. The quality standard of interior wall emulsioni paint relates to the quality of our home decoration environment, so when choosing interior wall emulsioni paint, we must pay attention to know how to choose the quality of emulsioni paint clearly.

Now the decoration is inseparable from the interior wall latex paint, we all know that paint is one of the sources of formaldehyde in the home, so many owners are concerned about the quality standard of the interior wall latex paint, let's understand:

1, free formaldehyde
The free formaldehyde in the interior wall coating mainly comes from synthetic resin emulsion and mildew inhibitor and other additives, which can ensure the chemical stability of the coating in the process of production and transportation and prolong the storage time of the coating. But free formaldehyde formaldehyde with the coating dry film, released into the environment, if the index exceeds the standard, easy to cause indoor air pollution, high concentration can cause nausea, vomiting, cough, chest tightness, asthma, emphysema, and even cause death, qualified coating free formaldehyde content is less than or equal to 0.1g/kg.
2. Volatile organic Compounds (VOC)
The content of total volatile organic compounds in interior wall coating should only affect human health and indoor environment pollution in the process of production, construction and use of coating, and the national implementation standard of this is ≤200g/L
3, freeze-thaw resistance
2008 revised "latex paint freeze-thaw resistance determination" in the determination of latex paint freeze-thaw resistance 244KB
4, washing resistance
Resistance to washing is one of the important technical indicators of interior wall coating, household life is easier to dirty wall, good coating can be wiped with water at any time, and will not be erased. The national standard stipulates that the washing resistance qualified product: ≥ 200 times; Grade A: ≥500 times; Superior quality ≥1000 times.
5, the ratio
The ratio is set for white and light color paint test items, it can reflect the ability of white and light color paint to eliminate the color or color difference on the substrate, can also indirectly reflect the amount of coating covering the same area of the substrate. The opposite ratio of coating is lower, the ability of product cover bottom material is poorer, coating effect is poorer, amount of unit area coating is bigger. The quality standard of interior wall emulsioni paint relates to the quality of our home decoration environment, so when choosing interior wall emulsioni paint, we must pay attention to know how to choose the quality of emulsioni paint clearly.
