Embodiment 1

[0043] Step 1: Before construction, add a formaldehyde stabilizer to the decoration auxiliary materials. The mass fraction of the formaldehyde stabilizer in the decoration auxiliary materials is 0.1%. The materials include wall solid, ground solid, putty powder, gypsum powder, 901 glue and white latex, and the formaldehyde stabilizer is polyvinyl formal;

[0044] Step 2: During construction, spray formaldehyde barrier agent on the exposed surface or cut surface of the wood products used for decoration. The formaldehyde barrier agent is used to block the release of formaldehyde from the board. The formaldehyde barrier agent is made of 0.1% glass fiber For plate coatings, formaldehyde barrier agent is sprayed on the surface of the plate twice according to the amount of 10-15 ml / square meter. The formaldehyde barrier agent is a paint containing 15% paraffin and ethylene oxide;

[0045] Step 3: After construction, test the formaldehyde content in the room, and comprehensively calc...

[0047] Step 1: Before construction, add a formaldehyde stabilizer to the decoration auxiliary materials. The mass fraction of the formaldehyde stabilizer in the decoration auxiliary materials is 10%. The materials include wall solid, ground solid, putty powder, gypsum powder, 901 glue and white latex, and the formaldehyde stabilizer is polyvinyl formal;

[0048] Step 2: During construction, spray formaldehyde barrier agent on the exposed surface or cut surface of the wood product used for decoration. The formaldehyde barrier agent is used to block the release of formaldehyde from the wood product. The formaldehyde barrier agent contains 0.9% glass Fiber board coating, formaldehyde barrier agent is sprayed on the surface of the board twice according to the amount of 10-15 ml / square meter, and the formaldehyde barrier agent is a coating containing 15% paraffin and ethylene oxide;

[0049] Step 3: After construction, test the formaldehyde content in the room, and comprehensively ...

Abstract

The invention relates to the field of formaldehyde removal in interior decoration, and discloses a method for preventing and controlling formaldehyde pollution in decoration engineering. The method comprises the following steps: 1, adding a formaldehyde stabilizer to a decoration auxiliary material, and performing stirring to achieve uniformity before construction, wherein the decoration auxiliarymaterial is a coating and / or an adhesive; 2, spraying a formaldehyde blocking agent on the exposed surfaces or the cut and notched surfaces of wood products used in the decoration during the construction, wherein the formaldehyde blocking agent is used for blocking the release of formaldehyde in the wood products; and 3, detecting and calculating the total release amount of formaldehyde in rooms,and spraying a formaldehyde cracking agent in the rooms after the construction. Different formaldehyde prevention and control technologies are used to prevent and control the indoor formaldehyde content at different stages in the decoration process, so the method reduces the superposed release of formaldehyde, effectively decomposes and converts a tiny amount of the residual released formaldehydefor a long term, and ensures that the decorated house after is safe and environmentally friendly and is suitable for people to live.

Description

technical field [0001] The invention relates to the field of indoor decoration formaldehyde removal, in particular to a method for preventing and controlling formaldehyde pollution in decoration engineering. Background technique [0002] Formaldehyde is a colorless gas with a strong pungent odor, easily soluble in water, alcohol and ether. The No. 153 Bulletin released by the World Health Organization in 2004 determined that formaldehyde is a carcinogenic and teratogenic substance. Formaldehyde is a recognized allergen, is also one of the potential strong mutagen, and is also one of the risk factors leading to childhood leukemia. According to domestic medical journals and related literature reports, the hazards of indoor formaldehyde to human health can be summarized as stimulating, toxic and carcinogenic. [0003] In interior decoration, formaldehyde is released from paints such as wood, planks, furniture, and walls in the family room. Indoor formaldehyde increases with t...
