From August 1, 2009, gb2626-2006 respiratory protective equipment self-priming filter type particle respirator was implemented, which stipulated that the protection levels for particles were Kn90, kn95 and kn100. The protection levels of oil particles are kp90, kp95 and kp100. The filtration efficiency was 90%, 95% and 99.97% respectively. Kn100 and kp100 are of high protection level. According to the national gb2626-2006 standard, the filter elements of dust masks shall be printed with permanent identification: ‘gb2626-2006-kn100’ national standard, year number and protection grade identification. The higher the degree of protection and filtering efficiency, the higher the safety of the dust mask.

Protection performance for fine particles (PM2.5) The protection effect level is set according to the air quality category in the national air quality standard. The protection effect level is divided into four levels from low to high: Level D, level C, level B and level A. The corresponding use environment is as follows: Level D is suitable for moderate (PM2.5 concentration no more than 150 g / m3) and below pollution, level C is suitable for severe (PM2.5 concentration no more than 250 g / m3) and below pollution, and level B is suitable for severe pollution Dye (PM2.5 concentration no more than 350? g / m3) and grade A are used when PM2.5 concentration reaches 500? g / m3. Wear mask reasonably according to the standard requirements, which can reduce the concentration of PM2.5 inhaled to less than 75? g / m3, and make the air quality in the inhaled body reach good or above level.

Liaocheng Shandong Wooden Floor Quality Control Service.

Floor acceptance criteria

1, See if the color of the floor is consistent. If the color difference is too large, directly affect the beauty, you can find the swap. Whether the color is consistent, there is almost no color difference, it depends on the pattern of the floor surface no the same. If the pattern is similar, it may be a process wood floor, rather than the so-called.
The flooring of the precious wood species. Now some flooring material suppliers, the use of general wood material .The floor, but on the surface of a layer of rare wood species of wood veneer to shoddy, said to be used to moisture-proof, in fact,for fear of being seen that the pattern on the back does not match the pattern on the front.

2, See whether the floor has a sound, acceptance on the floor. Walk up and down, step more, so especially near the wall and door parts should pay more attention to acceptance, found that there is a sound part, to repeat walking.
Determine the exact location of the sound and mark it. In this case, you can ask for removal and resurfacing. There are the part of the sound is that the construction personnel in the construction process, the operation is not standardized and the use of materials is not qualified. The non-standard operation is mainly reflected in the unstable fixing of the keel; The unqualified materials are mainly reflected in.The keel has not been dried. Some decoration construction units use undried keel construction on the surface.
There are drying marks. It’s not dry. A keel with a high moisture content, formed during the natural drying of wood the volume will shrink, causing loosening.

3. Check whether the floor is deformed and warped. The method of acceptance is to use a 2-meter long ruler and lean on it.On the floor, the flatness should not be greater than 3 mm. Take a few more measurements, if the pass rate is above 80%.It is regarded as qualified, otherwise, it is not qualified. Sometimes we find the floor partially arching: if it is a solid wood floor, which is because the floor is too tight or too dry (too low water content); if it’s laminate flooring. That means poor flooring. Therefore, the floor arch is a serious quality problem.
