Embodiment 1

[0027] Embodiment 1 discloses a specific implementation of a method for selecting materials for indoor decoration to control formaldehyde, including the following steps:

[0028] S10: Determine the target material that has the greatest impact on the formaldehyde concentration. In this embodiment, the target material that has the greatest impact on the formaldehyde concentration is obtained through data analysis of different construction nodes during the actual decoration process of the model house;

[0029] S20: Obtain the effective window-to-floor ratio R, material load D and the required formaldehyde concentration C specified in the completion acceptance of the interior decoration project for a single natural room s , the natural room refers to the independent closed space formed in the building, where people will stay during use, such as a bedroom with a door, a kitchen with a door, a bathroom and a hall with a door, etc.;

[0030] S30: judging whether there is a ventilatio...

Abstract

The invention discloses a material selection method for indoor decoration formaldehyde control. The method comprises the following steps that: after a target material is determined, obtaining an effective glazing floor area ratio R and the material load degree D of a single natural room and required formaldehyde concentration Cs during indoor decoration project completion acceptance; judging whether the natural room is provided with a ventilation system or not, adopting different formulas to calculate to obtain the formaldehyde maximum allowable emission concentration Cmax of the natural room,and then, judging whether any one of the following conditions is met or not: (1) the material load degree D is greater than or equal to 1 / 2; (2) the effective glazing floor area ratio R is less than1 / 20, and a heating system is in the presence; and (3) the effective glazing floor area ratio R is less than 1 / 20, and a ventilation system is in the absence. According to a structure, a material selection standard of a corresponding environment protection level or a higher environment protection level is selected. According to the required formaldehyde concentration during indoor decoration project completion acceptance, the material selection standard of the proper environment protection level is determined, reworking redecoration caused by improper material selection is avoided, indoor formaldehyde contents are guaranteed to reach the standard, and in addition, material cost can be reasonably controlled.

Description

technical field [0001] The invention relates to the technical field of indoor decoration pollutant control, in particular to a material selection method for indoor decoration to control formaldehyde. Background technique [0002] Formaldehyde in indoor air has become a major pollutant that affects human health. Since formaldehyde is listed as a first-class carcinogen, especially in winter, indoor formaldehyde exceeding the standard is the most harmful to the human body. [0003] In order to prevent and control the formaldehyde pollution of indoor air caused by the use of chemical building materials in interior decoration projects, the impact of toxic and harmful substances on human health should be minimized to ensure a healthy living and working environment for users. [0004] In order to meet the requirements of various countries for the control of interior decoration pollution, blindly selecting the most stringent materials will greatly increase the cost of materials, res...
