Do you think that "safety" is really safe during the renovation?

Do you think that "security" is really safe? Many people either believe in environmental protection when they buy building materials, or they are confused by traditional ideas. While paying great attention to pollution, they are self-defeating and ignore the real problem of pollution. Today, Xiao Bian gave everyone an analysis of the owners' misunderstandings about pollution when they decorated!

First, if you buy building materials, there are no problems with the selection of environmentally friendly materials.

Correcting: There are definitely not many decorators who have this idea, but families that have chosen the most environmentally-friendly building materials have exceeded the standard after the renovation. This is because some building materials such as wood-based panels, paints, and coatings inevitably contain harmful substances such as formaldehyde, VOC, and benzene. If a large area is used and several items are accumulated, the original individual’s environmental protection building materials will become Not so environmentally friendly or even exceeded.

Second, after the new house is renovated, you can rest assured that you will be able to stay in the hotel for a period of time.

Correct: This idea is incorrect. The harmful gases contained in the paints, plates and furniture used for decoration are slowly released. For example, the volatilization period of formaldehyde is as long as 8 to 15 years, that of benzene is 3 years, and that of ammonia is 1-3 years. This predestines the treatment of decoration pollution. It is a long-term process. Therefore, to achieve real reassurance, it is still necessary to ask the relevant professional inspection agencies to do a thorough inspection of the living room.

Third, it is said that the furniture is heavily polluted. Then I just waited for the furniture to come in and test it again.

Corrective: From the previous case of disputes concerning toxic and harmful gases in newly renovated houses, the owners did not rush to move newly purchased furniture and other daily necessities into their new homes before testing and acceptance of new houses because they may also release toxic and harmful gases. , will affect the results of testing the new house. The advantage of this is that once the new house detects that the concentration of toxic and harmful gases exceeds the standard, it can quickly clarify the limits of liability and facilitate the resolution of disputes as soon as possible.

Fourth, the newly renovated home has passed indoor air testing, and it should be able to sit back and relax.

Correct: Not necessarily. This is because the release of poisonous and harmful substances in decorative materials and furniture has the characteristics of increased release as the indoor temperature increases, and slower release as the indoor temperature decreases. In other words, if the new home meets the standards during winter testing, it may increase the temperature of the living environment due to the warming of the season or the heating of the living room and exacerbate the release, causing the concentration of toxic and harmful substances in the room to exceed the standard and endanger human health.

Hydraulic Flange fitting inculde SAE Code 61 and Code 62 Code 61 hydraulic fitting flange is intended for for pressures up to 3,000 psi. Code 62 is intended for up to 6,000 psi. Bolt hole spacing and flange fittinghead diameters are larger for the higher pressure Code 62 fittings.

The female port is an unthreaded hole with four bolt holes in a rectangular pattern around the port. The male hydraulic fitting is a flanged head, grooved for an O-ring, and either a captive flange or split flange halves with bolt holes to match the port. The seal takes place by compressing the O-ring between the flanged head and the flat surface surrounding the port. The threaded bolts hold the hydraulic connection together.
