Hemm żewġ tipi ta 'fibri taċ-ċeramika refrattorji: moduli tal-fibra taċ-ċeramika u blokki mitwija. Minbarra d-differenza fid-densità, il-moduli għandhom ankri u twavel tal-injam, filwaqt li l-blokki mitwija ma jagħmlux dan. Il-modulu tal-fibra taċ-ċeramika huwa magħmul prinċipalment minn kutra ta 'acupuncture tal-fibra taċ-ċeramika ta' materjal korrispondenti, li jiġi pproċessat fuq magna speċjali skont l-istruttura u d-daqs tal-komponent tal-fibra. Matul l-ipproċessar, huwa finalment iffurmat billi tagħfas skond l-ispeċifikazzjonijiet mixtieqa.
Il-moduli tal-fibra taċ-ċeramika huma maqsuma f'9 gradi skond it-temperatura operattiva, minn 900 grad C sa 1600 grad C, ordinarju, standard, għoli-purità, għoli-aluminju, żirkonju-aluminju , li fihom il-kromju-, li fihom iż-żirkonju-, eċċ., Li jistgħu jissodisfaw il-ħtiġijiet ta 'diversi fran u tagħmir termali. Gradi differenti ta 'partijiet differenti għandhom forom differenti ta' rekwiżiti ta 'insulazzjoni termali. Bl-avvanz tal-pjan nazzjonali tal--iffrankar tal-enerġija u t-tnaqqis tal-emissjonijiet, ir-rinnovazzjoni tal-forn tal-mina tal-ħruq tal-briks- hija imminenti, u l-modulu tal-fibra taċ-ċeramika ġie mfaħħar ħafna għall-prestazzjoni eċċellenti tiegħu ta 'insulazzjoni termali f' is-saqaf tal-forn tal-mina tal--ħruq tal-briks. Bir-riformi ewlenin fil-protezzjoni ambjentali, il-fibri taċ-ċeramika kellhom ċertu rwol fil-protezzjoni ambjentali.
The main components of ceramic fibers are Al2O3 and SIO2. Among them, the Al2O3 content in the high-alumina ceramic fiber module is relatively high (respectively, the chemical composition of ordinary type, standard type, high-purity type, high-aluminum type, and zirconium-containing type), which is 52 percent 55 percent , which belongs to injection fiber. It is also different from the spinning fiber. The diameter of the blown fiber is smaller, generally 2.03.0 μm, and the length of the fiber is shorter, generally 100200 mm. Because the fiber is thinner, the thermal conductivity is better than that of the spinning fiber. It is easily broken and torn during the folding process. On the other hand, the high-alumina type has a relatively high content of Al2O3, so it should be avoided in the kiln with electric heat as the heat source, so as to avoid the loss of personnel and property caused by electrical conduction, and the consequences are immeasurable. In general, the standard type is more commonly used, but the type of ceramic fiber module should also be selected according to the temperature of the kiln.
