Description
One, technical field:
The present invention relates to a kind of fireproof insulation brick, particularly relate to a kind of Thermal Equipment thermofin with light porous heat insulation refractory bricks and method of manufacture thereof.
Two, background technology:
Energy scarcity in the world wide; Various Thermal Equipments are the critical facilitys in the industrial production; It also is major power consumer; Therefore, the flame retardant coating of various Thermal Equipments and thermofin require insulation, fire-resistant, heat insulation, are that the Thermal Equipment long-term safety is used, saving energy and reduce the cost obtains the more assurance of large economy benefit.
At present, heat insulation, the thermal insulation fire-resistant brick of the various materials of manufacturing in the world wide adopt basically: (1) adds combustiblematerials, like plant saw foam, eps bead; (2) low density, low refractoriness light material are like fine perlite, closed perlite.The combustiblematerials that in (1) class methods, adds produces pore through burning to lose in the product sintering process; And the effect of acquisition lightweight, heat-insulation and heat-preservation; But the plant sawdust particularly burning of eps bead etc. loses and has wasted ample resources, and causes environmental pollution; In (2) class methods, pass through to add the low density light material, with the weight ratio of increasing small product size and product, and the effect of acquisition lightweight, heat-insulation and heat-preservation.Yet add the low density light material in large quantities; For example (its refractoriness is low has only 1350 ℃ to perlite; The category that does not belong to refractory materials strictly speaking) destroyed the high temperature use properties such as whole refractoriness, line velocity of variation of product; Do not reach the related prods request of national standard, thereby greatly reduce the work-ing life of Industrial Stoves, when serious even cause the generation of industrial accident.
Can be used to produce insulating fire brick to float pearl producer more; Electricity is thrown tafelberg Yaomeng power plant, tafelberg letter Xiang heat power plant, Huainan power plant, Huaibei power plant, the refreshing power plant in Shuozhou, Shanxi etc. in mainly containing; Pearl costs an arm and a leg and output is less but float, and can't carry out large-scale industrialization and use.Flyash is the sub product of coal power generation; But the flyash of output can be used to produce the less of insulating fire brick; Because to the performance requriements of former ash than higher; Electricity was thrown producers such as Yaomeng power plant, tafelberg letter Xiang heat power plant, the refreshing power plant in Shuozhou, Shanxi during the producer of one-tenth scale had at present, and the flyash output of these factories and quality can satisfy large-scale industrialization and use.
The patent No. is that 2004100238529 patent discloses be used to the to build a wall little foaming of lightweight of body of a kind of building trade and lays bricks, and is mixed by a certain percentage by sand, lime, clay/cement/white cement and whipping agent etc., gives typing after the foaming, cuts base, typing and processing.Used whipping agent is aluminium powder and water, owing to increased whipping agent, during the micro-bubble that whipping agent produces is evenly distributed in and lays bricks.That this brick has is in light weight, intensity is high, good water absorption, and characteristics such as soundproof effect is good are used brick but this brick is a common buildings, can not be used as refractory materials.
Three, summary of the invention:
The technical problem that the present invention will solve: be to overcome the shortcoming of thermal insulation fire-resistant brick in the background technology, a kind of compressive strength is high, thermal conductivity is low, the line velocity of variation is low, production cost is low ultramicropore high-intensity heat insulation refractory bricks and method of manufacture thereof are provided.
