Ms. Liu, who lives and feels happy, recently reported that her newly renovated house has been ventilated for a week. There is still a pungent odor in the air that makes itchy and even tearful. After testing by related departments, the content of formaldehyde, toluene, and xylene in the air was found to be significantly exceeded, in which the total toluene content exceeded 20 times that of the national standard, and formaldehyde exceeded the standard by more than 10 times. Ms. Liu was puzzled that the decoration materials she used were all branded environmentally friendly products and the prices were more expensive than ordinary materials. She did not know where the problems were.
Summer decoration should be as simple and practical as possible. Although decorative materials are all environmentally friendly, environmental protection of materials does not mean that the materials are non-toxic. Because indoor air pollution is a cumulative value. For example, if the formaldehyde content of a single piece of woodworking board is less than 0.08mg/m3, it will be regarded as a material environmental protection. If the amount of new housework woodboard is too much, furniture is too much and too much, the total amount of indoor formaldehyde and toluene may exceed the national standard. That is, even if all the environmentally friendly building materials are used, the amount of harmful substances in the indoor air will be unqualified once too much.
Due to the high temperatures in summer, the movement of toxic substances in the materials is accelerated, and these toxic substances are released in the form of gas and released quickly into the air. After the new home is installed, it is advisable to ventilate for one month. At the same time, formaldehyde scavengers or photocatalysts can be used to thoroughly clean indoor toxic gases.
Pre-evaluation of indoor air quality shall include engineering analysis, material calculation, determination of the release of toxic and harmful gases from building materials, quantitative calculation of toxic and harmful gases, suggestions for countermeasures, and evaluation conclusions. Because, environmental protection pre-evaluation is to help consumers to conduct health assessment of the decoration design program, determine the amount of building materials used to ensure that the design program will not cause indoor environmental pollution.

The installation of the countertop basin is easy, as long as the hole is opened on the countertop. There are a variety of sink edge designs for over-counter basin sink styles to choose from. It is necessary to ensure that the connection gap between the sink and the countertop is uniform, and there is no water seepage.
