ADSORPTION POLYMER FOR SOME KINDS OF VOCS, ALDEHYDE AND BASIC GASES: THE ADSORPTIVE CHARCTERISTICS AND EVALUATION IN FIELDS

摘要

A material of adsorptive polymer by graft polymerization was developed for the purpose of improving IAQ. The adsorption and sealing ability of the material was evaluated by adsorption isotherm with a simple and small glass chamber. The material applied to coating material and non-woven sheet has an adsorption ability for following perceived gaseous compounds in addition to formaldehyde: Acetaldehyde, toluene, styrene, ammonia,tri-methylamine and acetic acid. Addition of the material to the aldehyde- generating adhesive, mounting of that to bean-curd refuse and the gelled material mixed with agar were, respectively, effective for decrease of the odor gases. The coating material and the gelled material were applied to improve IAQ in new buildings as field test, and were evaluated by measuring VOCs concentrations of the indoor air.
