Ceramic fiber blanket layer structure, according to the different working temperature of each layer of blanket, choose ceramic fiber blankets with different temperature grades, densities, and thicknesses, the material selection is flexible, and the use is cost-effective; Parallel, the furnace lining has good thermal insulation performance, which greatly reduces heat loss.
01 The ceramic fiber blanket layer structure should be tested before construction; the upper and lower layers of the ceramic fiber blanket should be laid with staggered joints during construction, and the layers should be firmly pasted.
02 The national standard for alumina content in ceramic fiber blankets; the content of ordinary alumina is not less than 40%; the content of standard alumina is not less than 43%; the content of high-purity alumina is not less than 43%; high-alumina alumina The content is not less than 52%.
03 The thickness of the ceramic fiber lining must meet the design requirements of thermal insulation. Measurement method: record the length and width after measurement, and mark nine measurement points. When measuring, place the disk of the needle-type thickness gauge horizontally on the sample, align the hole of the disk with the measurement point, and insert the needle tip of the vernier into the hole of the disk carefully, when the needle tip touches the sample, press lightly. The cursor is used to read the thickness after the needle tip penetrates the sample and touches the glass plate.
04 After the ceramic fiber blanket furnace lining is installed, the surface of the fiber should be flat and beautiful, and squeezed tightly. The uneven parts should be flattened with splints; the larger gaps should be filled with ceramic fiber blankets to ensure good sealing performance of the fiber furnace lining.
SUNTHERM ceramic fiber products have corresponding test reports, in line with national standards, and we focus on the production of high-quality ceramic fibers!
