Core tip: the current haze problem has seriously threatened people's healthy living standards In order to resist air pollution, many consumers have bought air purifiers However, the formaldehyde and other pollutants in the home decoration are not completely solved by the air purifiers The environmental protection multi-functional diatom mud wall material can not only be green and healthy, but also adjust the indoor environment For consumers who buy diatom mud, the main reason for choosing this new material is that they want to decorate their home "healthy" In view of this, let's take a look at what kind of housing can be called healthy housing life 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 Paint Home News: the current haze problem has seriously threatened people's healthy living standards In order to resist air pollution, many consumers have bought air purifiers However, formaldehyde and other pollutants in the home decoration are not completely solved by air purifiers The environmental protection multi-functional diatom mud wall material can not only be green and healthy, but also adjust the indoor environment For consumers who buy diatom mud, the main reason for choosing this new material is that they want to decorate their home "healthy" In view of this, let's take a look at what kind of housing can be called healthy housing According to the World Health Organization (who) standard, healthy housing should meet 15 standards: 1 The concentration of the chemical substances that can cause allergy is very low 2 In order to meet the requirements of the first point, plywood and wall decoration materials that are easy to disperse chemicals shall not be used as much as possible 3 Equipped with a central air exchange device with good air exchange performance, which can regularly exchange air and discharge indoor pollutants to the outdoor 4 Local exhaust equipment shall be set in the kitchen 5 The temperature of living room, bedroom, kitchen, toilet, corridor, bathroom, etc shall be kept between 17 ℃ - 27 ℃ throughout the year   6 Indoor humidity is kept between 40% and 70% throughout the year 7 Carbon dioxide should be less than 1000 ppm 8 The concentration of suspended dust shall be less than 0.15mg/m2 9 The noise shall be less than 50 dB (a) 10 One day's sunshine shall be more than 3 hours 11 Lighting equipment with sufficient brightness shall be provided 12 The house has enough ability to resist natural disasters 13 Have enough per capita construction area and ensure privacy 14 The house should be convenient for the elderly and disabled 15 Because the building materials contain harmful volatile organic substances, the residence can not be moved in until a period of time after completion During this period, air change is required We can see that among the above 15 standards, the first, the second, the third, the fourth, the fifth, the sixth, the seventh, the eighth and the fifteenth are all related to air quality It can be seen that the quality of air is the key factor to determine the healthy housing Therefore, in order to have a real healthy house, when we decorate the house, we need to buy building materials and furniture, first of all, to ensure that these materials themselves must be environmentally friendly Among these harmful substances, formaldehyde is the most harmful to people Next, let's have a look all the time What are the regulations of domestic and foreign authorities on formaldehyde emission in materials E0 environmental protection standard purchase diatom mud identify f four-star to build a healthy house of international standard (picture from the network) national standard GB18582-2008 "limit of harmful substances in interior decoration materials interior wall coating" f ☆☆☆ environmental protection certification purchase diatom mud identify f four-star to build a healthy house of international standard (picture from the network) purchase diatom mud identify f four-star To build a healthy house with international standards (the picture comes from the network) From the comparison of the above three standards on the limit of free formaldehyde, we can see that the standard limit of F4 star is < 0.12mg/l, E0 is ≤ 0.5mg/l, and the national standard (GB) is ≤ 100mg / kg (1mg / kg ≈ 1mg / L) Through numerical comparison, we can see that F4 star is far higher than E0 and national standard GB18582-2008 F4 star is by far the most stringent environmental protection standard for building materials in the world Therefore, when our consumers choose diatom mud wall, they should also recognize which diatom mud manufacturers have F4 star certification to ensure that the diatom mud products they buy are indeed the most stringent Environmentally friendly products Home of coatings focuses on the news and information of coatings, diatom mud, paint coatings, coating process, fire retardant coatings and coatings, paint coatings, coating process, decoration knowledge and decoration effect map of fire retardant coatings,
