Analysis of application cases of polyurethane sponge aldehyde removal agent in office air purification and future development trends

Introduction

With the continuous upgrading of modern office environments, indoor air quality issues are increasingly attracting attention. Hazardous gases such as formaldehyde and benzene are the main sources of office air pollution. Long-term exposure to these harmful gases will have serious impacts on human health. As a new type of air purification material, polyurethane sponge aldehyde removal agent has gradually become a popular choice for office air purification due to its efficient adsorption, long-lasting and stable, environmentally friendly and non-toxic properties. This article will comprehensively analyze the application value of polyurethane sponge aldehyde removal agent in office air purification through case analysis, product parameter interpretation and future development trend discussion.

1. Characteristics and advantages of polyurethane sponge aldehyde removal agent

1.1 Product Features

Polyurethane sponge aldehyde removal agent is a porous material with polyurethane as the base material and loading efficient aldehyde removal components through special processes. Its characteristics mainly include:

• High specific surface area: Polyurethane sponges have rich pore structure and large specific surface area, which can effectively adsorb formaldehyde molecules in the air.
• Chemical adsorption combined with physical adsorption: Aldehyde removal agent not only captures formaldehyde through physical adsorption, but also converts formaldehyde into harmless substances through chemical reactions.
• Environmental and non-toxic: The material itself is non-toxic and harmless, and there will be no secondary pollution during use.
• Durable and stable: The aldehyde removal effect can last for months or even years, and is suitable for long-term use.

1.2 Comparison with traditional aldehyde removal methods

Comparison	Polyurethane sponge aldehyde removal agent	Activated Carbon Adsorption	Photocatalyst decomposition	Plant purification
Adsorption efficiency	Efficient	Medium	Depend on lighting conditions	Inefficient
Permanence	Durable (6-12 months)	Short (1-2 months)	Rely on light sources	Sustainable but limited effect
Environmental	Environmentally friendly and non-toxic	Environmentally friendly but easy to saturate	Can produce secondary pollution	Environmentally friendly but limited effect
Scope of application	Wide	Small scope	Lighting environment	Small scope
Cost	Medium	Low	High	Low

It can be seen from the table that polyurethane sponge aldehyde removal agent has obvious advantages in adsorption efficiency, durability and scope of application, and is an ideal choice for office air purification.

2. Application cases of polyurethane sponge aldehyde removal agent in office air purification

2.1 Case background

A large technology company's office building in a first-tier city has generally reported symptoms such as dizziness and stinging eyes due to the excessive formaldehyde released by the decoration materials. The company decided to use polyurethane sponge aldehyde removal agent for air purification to improve the office environment.

2.2 Implementation process

1. Preliminary Test: Use professional instruments to detect the formaldehyde concentration in the air in the office, and the results show that the average concentration is 0.15 mg/m³, exceeding the national standard (0.1 mg/m³).
2. Product Selection: Select a certain brand of polyurethane sponge aldehyde removal agent, and its main parameters are as follows:

parameters	Value/Description
Material composition	Polyurethane substrate + nanoaldehyde removal agent
Adsorption capacity	Add 0.5 mg of formaldehyde per gram of material
Service life	6-12 months
Applicable area	Use 1-2 blocks per square meter
Environmental Certification	Passing SGS environmental testing

3. Installation: Arrange aldehyde removal agents in every corner of the office, vents and near formaldehyde release sources to ensure air circulation.
4. Last-stage monitoring: Every other monthDetect the formaldehyde concentration once and record the data changes.

2.3 Effect analysis

Time	Formaldehyde concentration (mg/m³)	Employee Feedback
Initial Phase	0.15	Dirty, stinging eyes
1 month later	0.10	Symptoms are significantly reduced
3 months later	0.08	No discomfort symptoms
6 months later	0.05	Good air quality

From the data, it can be seen that after using polyurethane sponge aldehyde removal agent, the formaldehyde concentration in the office air dropped significantly, the discomfort symptoms of employees gradually disappeared, and the air quality was significantly improved.

III. Technical principles and product parameters of polyurethane sponge aldehyde removal agent

3.1 Technical Principles

The core technology of polyurethane sponge aldehyde removal agent lies in its porous structure and the supported nanoaldehyde removal components. Its working principle can be divided into the following steps:

1. Physical Adsorption: The porous structure of polyurethane sponges can capture formaldehyde molecules in the air.
2. Chemical Decomposition: The supported nanoaldehyde remover chemically reacts with formaldehyde to convert it into water and carbon dioxide.
3. Continuous Release: Aldehyde Removal agent slowly releases active ingredients during adsorption and decomposition to ensure long-term results.

3.2 Detailed explanation of product parameters

parameters	Value/Description	Significance Analysis
Adsorption capacity	Add 0.5 mg of formaldehyde per gram of material	Reflects the adsorption capacity of the material
Porosity	85%-90%	The higher the porosity, the better the adsorption effect
Density	20-30kg/m³	Moderate density, easy to install
Temperature resistance range	-20℃ to 80℃	Adapting to different ambient temperatures
Environmental Certification	SGS detection	Ensure that the material is non-toxic and harmless
