How to Judge the Quality of Aluminum Silicate Fiber Cotton

Introduction

Appearance and Surface Quality

• The surface should be flat and smooth.
• Check for any scratches, stains, or damages that may affect usability.

Moisture Absorption

• Quality fiber cotton has a moisture absorption of 3.9% per square meter in the air.
• This helps maintain a dry and moisture-proof environment.

Density

• The density range should be ±3100-3100 mg/kg.
• This meets the standard requirements for aluminum silicate fiber products.

Chemical Composition

• Analyze the chemical composition to understand its hygroscopicity and other properties.

Thermal Conductivity

• Look for low thermal conductivity, indicating good thermal insulation performance.

Dimensional Stability and Flexibility

• Assess the dimensional stability and flexibility to ensure it meets application requirements.

Fire Resistance

• Verify that it is non-combustible and meets fire safety standards.

Chemical and Moisture Resistance

• Check its resistance to chemicals and moisture to ensure it can withstand various environmental conditions.

Heat Capacity

• Consider the heat capacity to determine its efficiency in thermal management.

Thermal Shock Resistance

• Evaluate its ability to withstand temperature shocks if used in fluctuating temperature environments.

Processability

• Consider how easy it is to cut and process the material to suit specific needs.

Weight

• Take into account the lightweight nature of the product for ease of handling and installation.

Wind Erosion Resistance

• Assess its wind erosion resistance based on its texture and toughness.
