Quartz Fiber Infiltrated Substrate Panels

Composition & Structure:
"
Main constituents:
Quartz sand, cement and wood-pulp fiber are the primary raw materials. Some grades further use premium Portland cement and high-silica quartz sand as the binder, reinforced by high-quality imported virgin cellulose fibers."
Molecular structure:
The dominant component, silicon dioxide (SiO₂), forms a three-dimensional network. Each silicon atom sits at the center of a tetrahedron, covalently bonded to four oxygen atoms, creating SiO₄ tetrahedral units. These units link by sharing oxygen atoms, extending infinitely in all directions.
Crystal structure: 
The material crystallizes in the trigonal system, exhibiting high symmetry and order. Si–O bond lengths and angles are fixed, resulting in a densely packed, well-ordered atomic arrangement.

Features:
"1: Outstanding fire resistance--
Achieves Class A non-combustibility; remains stable at temperatures up to 1,200 °C for continuous use and has a softening point of 1,700 °C, significantly slowing flame spread and reducing fire risk."
"2: Superior chemical stability--
Highly resistant to acids, alkalis, and salts. Chemical agents cannot readily break the strong Si–O bonds or disrupt the molecular framework, ensuring long-term performance in corrosive environments such as chemical plants or marine settings."
"3: Excellent electrical insulation--
Electrons are tightly bound within covalent bonds, and the highly ordered crystal lattice is free of significant defects or impurity energy levels. This strongly impedes electron mobility, providing reliable electrical isolation and safe operation of equipment."
"4: High mechanical strength (with brittle nature)--
The three-dimensional covalent network of SiO₄ tetrahedra confers notable tensile, flexural, and compressive strength, enabling the panel to bear structural loads. Being intrinsically brittle, however, it is susceptible to crack propagation and fracture under impact loading."
"5: Moisture and antimicrobial resistance--
Inherently stable in humid conditions, the material resists moisture absorption and deformation while suppressing bacterial growth, helping maintain a clean environment."
"6: Outstanding dimensional stability--
Strong interatomic interactions preserve structural integrity under varying temperature and pressure. The panel effectively withstands thermal stress and minimizes thermal expansion, ensuring consistent dimensions even in high-temperature conditions."
