Ceramic fiber board uses blown fiber, which is different from the production of fiber blankets. The fiber blanket uses spinnable fibers. Unlike blown fibers, blown fibers are short and thin, and are easy to break. As a raw material for ceramic fiberboard, a certain proportion of binders and filler-level additives are added, and through a beating machine, it is fully dispersed into a slurry in the slurry tank. Pump into the forming tank and stir with compressed air. Put the mold into the forming tank, use the principle of vacuum to dehydrate the wet fiber material, release the mold, put it in the tray and send it to the drying furnace for 10-24 hours. After drying, the fiberboard is controlled by a special grinding machine and edge trimming machine.
Ceramic fiber insulation supplier believes that: ceramic fiberboard has excellent chemical stability; excellent thermal stability, product texture is hard, after heating, it also maintains good mechanical strength, toughness and strength, wind erosion resistance Strong, high compressive strength, long service life; low thermal capacity, low thermal conductivity; non-brittle material, good toughness; good size, flatness; easy to cut and install, and convenient construction. Compared with fiber blankets and felts, the ceramic fiberboard has a certain hardness and better support performance.
Because of its excellent performance, it is widely used in the thermal insulation of heat treatment furnaces; the thermal insulation of furnaces in cement and other building materials industries; the thermal insulation of furnaces in petrochemical, metallurgical, ceramics, and glass industries; and it can also be used for high-temperature reaction and heating Equipment backing insulation; non-ferrous metal industry backing insulation.
Ceramic Fiber Blanket
The difference between the ceramic fiberboard felt and aluminum silicate fiber blanket
It may be due to the difference in region and name. Customers often call ceramic fiber blanket as ceramic fiber blanket. In fact, ceramic fiber blanket and ceramic fiber blanket are two completely different products, although their materials and uses are similar. However, there are many differences between the two in many ways.
(1) Volumetric weight:
The density of the ceramic fiberboard felt is between 220-280, and the density of the ceramic fiber blanket is 90-128, so the felt is a relatively hard material. The ceramic fiber blanket is loose, as the cotton in the quilt, It is made of loose cotton needles.
Ceramic fiber blankets are relatively soft, so they can be wrapped around and stacked, and are widely used in practical applications. Ceramic fiber mats are relatively hard and can only be used flat, not folded or bent. For example, in the thermal insulation of pipelines, ceramic fiber blankets can only be used for wrapping, and ceramic fiber mats cannot be used.
(3) Comparison of thermal insulation effect:
Because the ceramic fiber blanket is relatively loose and there are many empty spaces in the middle, it can well prevent the hot airflow. No matter what the bulk density is, just choose a blanket with a suitable thickness. The quality of the ceramic fiber mat is 220 bulk density Very poor and rough surface, there will be open space between the furnace walls after use, the thermal insulation effect is not as good as ceramic fiber blanket, if you need certain hardness information, you can use ceramic fiberboard instead of ceramic fiber board felt.
(4) Compared with the price, the price of ceramic fiber blanket is lower than that of the ceramic fiber board felt, and the transportation and construction are relatively simple, so the price of ceramic fiber blanket is better.
