Noise suppression of reactive gel catalysts in public transportation

Introduction

With the acceleration of urbanization, public transportation such as subways, buses, light rails, etc. have become an important way for people to travel on a daily basis. However, the noise problems generated by these vehicles during operation are becoming increasingly prominent, which not only affects passenger comfort, but may also cause noise pollution to the surrounding environment. To solve this problem, reactive gel catalysts are widely used in the field of noise suppression as a new material. This article will introduce in detail the noise suppression application of reactive gel catalysts in public transportation, including its working principle, product parameters, practical application cases, etc.

Basic concepts of reactive gel catalysts

What is a reactive gel catalyst?

Reactive gel catalyst is a gel material with high reactive activity, usually composed of polymers and catalysts. Its unique structure enables it to react chemically under specific conditions, thereby achieving effective suppression of noise.

Working Principle

Reactive gel catalysts achieve noise reduction effects by absorbing and converting noise energy. When noise waves pass through the gel material, the catalyst in the gel triggers a series of chemical reactions that convert noise energy into thermal energy or other forms of energy, thereby reducing the spread of noise.

Application of reactive gel catalysts in public transportation
