The modification of the traditional interior wall paint was carried out by means of adding nano-TiO_2 as a functional pigment.By regulating the dosage of dispersant,the nano-particles can be dispersed in paint homogeneously.With two aspects of experiments:dosage of nano-TiO_2 and pigment volume concentration (PVC),the paint formulation can be optimized and its properties,such as hardness,scrub resistance,storage stability,contrast ratio and gloss can be improved.Finally an interior wall paint with high performance and air purification was prepared.Its character of formaldehyde degradation would be discussed in the next article. 相似文献

在我国内部审计制度发展之初,政府无意干涉民营企业内部审计制度的建立。随着民营企业的发展,基于提高自身经营活动的效益性需要,民营企业自发地开展了内部审计工作。但民营企业内部审计的自主发展存在诸多弊病。随着我国内部审计制度的发展和完善,民营企业内部审计逐渐被纳入政府统一管理的范围。民营企业内部审计工作在制度的推动下必将得到进一步的发展。 相似文献

A novel nano-TiO2-xNx composite was used as photocatalyst and added to the interior wall paint. The average diameter of nano-TiO2-xNx was about 20 nm. The majority crystal component of the sample was anatase and its optical absorption edge was shifted from 387 nm to 520 nm significantly. Nano-composite paint containing different dosage of nano- TiO2-xNx was investigated to study the properties of formaldehyde decomposition in the air. Testing results show that the formaldehyde decomposition ratio of that nano-paint can almost reach above 80%, especially for that of the paint containing 3% （w/w） nano-TiO2-xNx which exceeded 90%. The primary investigation on the reaction kinetics of photocatalytic formaldehyde decomposition indicated that the experiment data well fit the model of first-order reaction kinetics. 相似文献

Computational fluid dynamics simulation of formaldehyde emission characteristics and its experimental validation in environment chamber 总被引：1，自引：0，他引：1
We investigated the effect of supply air rate and temperature on formaldehyde emission characteristics in an environment chamber. A three-dimensional computational fluid dynamics （CFD） chamber model for simulating formaldehyde emission in twelve different cases was developed for obtaining formaldehyde concentration by the area-weighted average method. Laboratory experiments were conducted in an environment chamber to validate the simulation results of twelve different cases and the formaldehyde concentration was measured by continuous sampling. The results show that there was good agreement between the model prediction and the experimental values within 4.3% difference for each case. The CFD simulation results varied in the range from 0.21 mg/m3 to 0.94 mg/m3, and the measuring results in the range from 0.17 mg/m3 to 0.87 mg/m3. The variation trend of formaldehyde concentration with supply air rate and temperature variation for CFD simulation and experiment measuring was consistent. With the existence of steady formaldehyde emission sources, formaldehyde concentration generally increased with the increase of temperature, and it decreased with the increase of air supply rate. We also provided some reasonable suggestions to reduce formaldehyde concentration and to improve indoor air quality for newly decorated rooms. 相似文献
