Aplicarea plăcii din fibră ceramică de silicat de aluminiu

An aluminum silicate ceramic fiber board is a fiberboard used for heat insulation and can maintain good mechanical strength even under heating.

What is ceramic fiber?

Fibră ceramică cunoscut și sub denumirea de silicat de aluminiu, is a fibrous lightweight refractory material with light, rezistență la temperatură ridicată, conductivitate termică scăzută, and miniature thermal melting.

The production principle of ceramic fiberboard

Fiber is used as the raw material of ceramic fiberboard, and a certain proportion of binder and filler-level additives are added, and it is fully dispersed into a slurry in the slurry mixing tank through a beater. Pump into the forming pool and stir with compressed air. Put the mold into the forming tank, and use the principle of vacuum to make the fiber slurry adsorb on the mold.

Accurately control the adsorption time, vacuum dehydrates the wet fiber material, remove the mold, put it on the tray, and send it to the drying oven for 10-24 hours. The dried fiberboard is passed through a grinder and edge trimmer to precisely control the size. So the size of the ceramic fiberboard can be customized.

Properties of ceramic fiberboard

In addition to the excellent performance of the corresponding loose ceramic fiber cotton, the ceramic fiberboard has a hard texture, excellent toughness, and strength, and excellent wind erosion resistance. It does not expand when heated, is light in weight, convenabil în construcții, and can be cut and bent at will. It is an ideal energy-saving material for kilns, conducte, and other insulation equipment.

Precautions for using ceramic fiber products

Safe operation

When installing, using, and maintaining ceramic insulation products, be sure to follow the relevant safety operating procedures and usage guidelines.

Temperature limits

Make sure that the selected ceramic insulation product can accommodate the required operating temperature range. Exceeding its temperature range may result in material failure or reduced performance.

Installation quality

Correct installation is the key to ensuring the performance of ceramic insulation products. Install according to the installation guidelines provided by the refractory manufacturer and ensure proper fastening, etanșare, and support. Avoid creating voids or gaps to ensure continuity and insulation of the insulation.

Maintenance inspections

Regularly inspect the condition of ceramic insulation products, including damage, corrosion or aging. If a problem is found, repair or replacement measures should be taken in time to ensure its normal heat insulation performance.

Environmental adaptability

Ceramic insulation fiber products should choose materials and types that meet the requirements of the actual working environment. Considering chemical corrosion, mechanical vibration, gas erosion, and other factors, choose products with high durability and adaptability.

Thermal expansion

The thermal expansion coefficients of the ceramic insulation product and the underlying structure should match. Proper thermal expansion control can reduce thermal stress and the risk of cracking.

Fire resistance

The fire resistance of ceramic fiber products is critical for high-temperature industrial environments. Make sure that the selected product complies with relevant fire resistance standards and has sufficient fire resistance to protect equipment and improve work safety.
