Материали за одеяло

Огнените одеяла са изработени от влакнести топлинни, инсулиращи огнеупорни материали, огнеупорни влакна . огнеупорни влакна имат характеристиките на общите влакна, като мекота, еластичност и определена якост на опън . Те могат да бъдат обработени допълнително в различни продукти, като хартия, въже, колан, одеяло и усещане; they also have high temperature resistance and corrosion resistance that general fibers do not have. As a refractory insulation material, it has been widely used in metallurgy, chemical industry, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.
Класификация на материалите
Refractory fibers are divided into two categories: amorphous (glassy) and polycrystalline (crystalline). Amorphous refractory fibers include aluminum silicate, high-purity aluminum silicate, chromium-containing aluminum silicate and high-aluminum refractory fibers. Polycrystalline refractory fibers include Mullite влакна, алуминиеви влакна и циркониеви оксидни влакна . (Таблица 1) Има и класификации въз основа на максималната допустима температура на използване на огнеупорни влакна .
Характеристики на класификация на материали
Refractory fibers are also good infrared radiation materials with good thermal capacity and infrared heating effect. The use of refractory fiber products can effectively save energy and is an ideal energy-saving and efficiency-enhancing material. Production practice has proved that the application of refractory fiber in continuous heating industrial furnaces can save more than 15% of energy, and the use of refractory fiber in intermittent industrial heating furnaces can save more than 30% of energy. At the same time, it can improve productivity and product quality, realize the lightweight and large-scale structure of the furnace body, and have good comprehensive performance. Refractory fiber is soft and elastic, and is also an ideal sealing material. Due to its insulation, silencing, anti-oxidation, oil and Водоустойчивост и удобно строителство, тя се използва широко в металургията, строителните материали, петрола, химическата промишленост, корабостроенето, електричеството, аерокосмическото и други полета .
Polycrystalline refractory fiber is a new type of high-temperature insulation material developed after amorphous refractory fiber in the early 1970s. It is mainly used in high-temperature kilns with working temperatures above 1400℃, which can save energy by 25% to 40%. Polycrystalline refractory fiber can also be used as a composite reinforcement material and catalyst carrier, with good application effect. Polycrystalline refractory fiber can also be used in aerospace missiles and atomic energy fields. The polycrystalline refractory fibers that have been industrially produced and applied internationally mainly include polycrystalline alumina fibers (Al2O3 80% ~ 90%, Sio 2 21%~ 20%), поликристални мулитни влакна (Al2o 3 72%~ 79%, Sio 2 21%~ 28%) и Polycrystalline Zirconia Fibers (Zro 2 92%, Y2O 3 8)
