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.
