The chemical stability of aluminum silicate fiber module is one of the most important characteristics in industrial application, which has a significant impact on the performance and service life of the module. The following is a concrete analysis:

I. Influence of chemical stability on application

Corrosion resistance: The main components of aluminum silicate fiber module are aluminum oxide (Al₂O₃) and silicon dioxide (SiO₂), which have good chemical stability and usually do not react with acid and alkali. This feature enables it to run stably in a complex chemical environment for a long time, such as in high-temperature reaction furnaces, cracking furnaces and other equipment in the chemical industry, and can effectively resist the erosion of chemical media.

Prolonged service life: Due to its chemical stability, the aluminum silicate fiber module is not easy to be corroded or decomposed by chemicals at high temperature, thus significantly prolonging the service life. For example, in the high-temperature furnace in metallurgical industry, the module can withstand the double tests of high temperature and chemical medium, and reduce the equipment damage caused by material corrosion.

Safety improvement: chemical stability also means that under extreme conditions such as high temperature or fire, the aluminum silicate fiber module will not release harmful gases or have chemical reactions, thus improving the safety of the equipment.

II. Chemical stability of different types of aluminum silicate fiber modules

Ordinary module: it is suitable for low-temperature environment below 900℃, with good chemical stability, but relatively weak tolerance to strong acid and alkali.

High-purity module: the raw materials have higher purity and better chemical stability, which is suitable for high-temperature environment of 1200℃-1300℃ and can resist the corrosion of most chemical media.

Zirconium-containing module: by adding zirconia (ZrO₂), the chemical stability and thermal shock resistance are further improved, and it is suitable for extremely high temperature environment of 1300℃-1400℃. This module performs well in glass melting furnaces and high temperature furnaces in steel industry.

Polymorphic module: it has extremely high chemical stability and temperature resistance, and is suitable for ultra-high temperature environment above 1400℃, such as aerospace and nuclear industry.

III. Embodiment of chemical stability in specific applications

Petrochemical industry: In cracking furnace, reforming furnace and other equipment, aluminum silicate fiber module can withstand the double tests of high temperature and chemical medium, and its chemical stability ensures the long-term stable operation of the equipment.

Metallurgical industry: In high-temperature furnaces and heat treatment furnaces, the chemical stability of the module enables it to resist the corrosion of molten metal and high-temperature gas.

Environmental protection industry: in waste incinerator and RTO waste gas treatment equipment, chemical stability ensures the long-term use of modules in high temperature and corrosive gas environment.

IV. Influence of chemical stability on installation and maintenance

Simple installation: Due to chemical stability, the aluminum silicate fiber module does not need additional chemical protection measures during installation, which reduces the installation difficulty.

Low maintenance cost: its chemical stability reduces material damage caused by chemical corrosion and reduces maintenance cost.

To sum up, the chemical stability of aluminum silicate fiber module is one of its core advantages in high temperature industrial applications. It not only improves the safety and reliability of equipment, but also prolongs the service life and reduces the maintenance cost, making it an ideal high-temperature heat insulation material.
