The application of delayed amine hard bubble catalyst in sports venue construction: Ensure the durability and safety of site facilities

Introduction

As a large public building, the construction quality of the sports stadium is directly related to the safety and experience of athletes and spectators. In recent years, with the continuous advancement of building materials, delayed amine hard bubble catalysts have been widely used in the construction of sports venues. This material not only improves the durability of the building structure, but also effectively enhances the safety of the site. This article will introduce in detail the characteristics, application of delayed amine hard bubble catalyst and its specific role in the construction of stadiums.

1. Overview of delayed amine hard bubble catalyst

1.1 Definition and Features

The delayed amine hard bubble catalyst is a chemical additive used in the production of polyurethane foam. Its main function is to adjust the reaction speed of the foam so that it can achieve the best foaming effect within a specific time. This catalyst has the following characteristics:

Delayed reaction: Can delay the reaction time after foam mixing to ensure uniform distribution of the foam.
High stability: It can maintain a stable catalytic effect in both high and low temperature environments.
Environmentality: Low volatile organic compounds (VOC) emissions, comply with environmental protection standards.

2. Application of delayed amine hard bubble catalyst in sports venue construction

2.1 Application of site foundation layer

The foundation layer of the stadium is a key part of ensuring the stability and durability of the venue. The application of delayed amine hard bubble catalyst in the base layer is mainly reflected in the following aspects:

Uniform foaming: By delaying the reaction, ensure that the foam is evenly distributed in the base layer to avoid voids or uneven density.
Reinforcement strength: The uniform distribution of the foam can effectively improve the overall strength of the foundation layer and reduce deformation or cracking caused by external forces.

2.2 Manufacturing of stands and seats

The stands and seats are parts of the stadium that are directly in contact with the audience, and their safety and comfort are crucial. The applications of delayed amine hard bubble catalysts in stand and seat manufacturing include:

Shock Absorption Effect: By adjusting the density and elasticity of the foam, it provides good shock absorption effect and reduces the fatigue of the audience when watching the game for a long time.
Fire Resistance: The delayed amine hard bubble catalyst can improve the fire resistance of the foam and ensure the safety of the audience in an emergency.

2.3 Insulation of roof and walls

The roofs and walls of sports stadiums need to have good thermal insulation properties to cope with climate change in different seasons. The application of delayed amine hard bubble catalyst in thermal insulation materials is mainly reflected in:

High-efficiency insulation: By optimizing the closed-cell structure of foam, the insulation performance of insulation materials can be improved and energy consumption will be reduced.
Waterproof and moisture-proof: The closed-cell structure of the foam can also effectively prevent moisture penetration and extend the service life of the building.

3. Effect of delayed amine hard bubble catalyst on the durability and safety of stadiums

3.1 Improve durability

The delayed amine hard bubble catalyst significantly improves the durability of sports venues by optimizing the structure and performance of the foam. Specifically manifested in:

Anti-aging: Foam materials are not prone to aging during long-term use and maintain stable physical properties.
Impact Resistance: The high elasticity of the foam can effectively absorb impact force and reduce damage caused by external forces.

3.2 Enhanced security

Safety is the top priority in the construction of stadiums. The role of delayed amine hard bubble catalysts in enhancing safety include:

Fireproofing and flame retardant: reduces the risk of fire by improving the fire resistance of foam.
Shock Absorbing cushioning: It is used in stands and seats to effectively reduce the audience’sInjury under unexpected circumstances.
