1. Appearance quality: The surface should be flat and free of any scratches, stains, or damages that may hinder practical use.
2. Strong hygroscopic properties, as well as the ability of metal surfaces to adsorb water molecules, are related to the properties of metal elements and surface structural states. The moisture absorption of aluminum silicate fiber cotton in the air is 3.9% per square meter, which can prevent moisture and keep the room dry. Hygroscopicity refers to the property of a material that can absorb moisture in the air, which is related to the chemical composition and structure of the material.
3. The density range of aluminum silicate fiber cotton is kg/m3 100-250 ± 16%, and products within this density range meet quality requirements.
