New house decoration formaldehyde treatment

2018-02-27 06:24:00

According to the survey statistics, 90% of newly renovated homes exceed the standard of formaldehyde. Formaldehyde is colorless and pungent smell of toxic chemicals, only when formaldehyde exceeded 3 times to smell, which is easy to cause some consumers wrong understanding that no taste is no formaldehyde.

Tools/Materials
1

Spectrophotometer testing instrument

2

Nano visible light photocatalyst

3

Air compressor

4

Spray gun

Methods/Steps
1

According to the national standard indoor sealing for more than 1 hour or more than 12 hours

2

The use of spectrophotometer to detect the formaldehyde content, the general home national standard is 0.08mg/m³, is 0.1mg/m³, the detection time is 10 minutes or 20 minutes, according to the collection of flow to control

3

Within a week is the most concentrated release of benzene series and formaldehyde, but the formaldehyde volatilization cycle is as long as 3 to 15 years, and the harm of formaldehyde is well understood

4

If formaldehyde exceeds the standard, we often use ventilation, sleeve leather, plants, tea and other methods is to cure the symptoms rather than cure the root, first of all, we have to start from the material selection, choose environmentally friendly materials, environmentally friendly materials do not contain formaldehyde, but very little, and then choose a fast and effective way to remove formaldehyde, nano photocatalyst is the use of reoxidation reduction reaction to decompose toxic gases into carbon dioxide and water

5

Select the photocatalyst construction team, clean and clean, the humidity is not too large, keep it at about 50%, and empty the closet and drawer in the home, which is convenient for the construction personnel to achieve the best effect

6

Open the air compressor, connect the spray gun, adjust the spray gun, pour the decomposition enzyme, test the spray effect, and start construction

7

Ensure that each space is sprayed in place, sealed for half an hour, the decomposition enzyme is mainly to remove odor, and quickly remove free formaldehyde and benzene series in the air

8

Ventilation for half an hour, so that the taste of the decomposition enzyme dispersed, began to spray the photocatalyst, to achieve long-term decomposition of formaldehyde effect

9

Seal for half an hour, and then ventilate for half an hour, and maintain the ventilation state for 3 to 7 days, you can achieve long-term purification of toxic gases such as formaldehyde and benzene

Matters needing attention
1

Clean up thoroughly

2

The fluorescent lights should be turned on

3

In winter, the air conditioner should be turned on to dehumidify and heat up

4

Spray carefully

5

Ventilation time should be sufficient
