Abstract
The invention relates to a novel inorganic fiber thermal insulation blanket and belongs to the technical field of thermal-insulation heat-protection fire-retardant materials. The novel inorganic fiber thermal insulation blanket consists of the following ingredients by weight percent: 40.0-85.0% of SiO2, 0-40.0% of Al2O3, 2.0-40.0% of CaO, 1.0-20.0% of MgO, 0-1.0% of Fe2O3, 0-1.0% of K2O and 0-1.0% of Na2O. Due to a unique production technology, the low content of fiber residue balls and the thinness of fiber diameter are ensured, and therefore, the fiber blanket is soft without irritating skin and has good environment-friendliness; the novel inorganic fiber thermal insulation blanket has a neat appearance and is pure white; the maximum normal breadth of the novel inorganic fiber thermal insulation blanket is 910mm so that the convenience for construction is ensured; and the novel inorganic fiber thermal insulation blanket belongs to an indefinite form product, can be constructed according to the requirements of users and can achieve safety, simplicity and feasibility without special packaging requirements.
Description
Technical field
The present invention relates to a kind of novel inorganic fiber thermal insulation blanket, belong to the heat insulating technical field of refractory materials.
Background technology
Traditional inorganic heat insulation material comprises glass wool, rock wool etc., and use temperature is generally below 500 ℃, and below 250 ℃, the rock wool use temperature is below 450 ℃ such as the use temperature of glass wool.At present, still do not have for the fibrous heat insulator under 450 ~ 800 ℃ the Working environment, therefore develop this novel fibrous heat insulator, both be used for 450-800 ℃ thermal environment, substitute again traditional lagging material using below 450 ℃, significant.
Have wide range of applications, be applicable in the heat-insulation system of all kinds of cold and hot medium pipelines of industrial circle such as electric power, metallurgy, chemical industry, medicine, light textile, boats and ships, vehicle, electrical equipment and container, significantly improve heat utilization rate, reduce client's production power consumption and cost, for the client creates higher value.
Summary of the invention
According to the deficiencies in the prior art, the technical problem to be solved in the present invention is: a kind of novel inorganic fiber thermal insulation blanket is provided, and high insulating effect solves the vacancy of the fibrous heat insulator under 450 ~ 800 ℃ the Working environment.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel inorganic fiber thermal insulation blanket is provided, has following weight percent and form:
Described inorganic fibre is the inorganic silicate fiber.
Described inorganic silicate fiber is aluminum silicate fiber, soluble fibrous magnesium silicate or ca silicate fibre.
The leading indicator of described inorganic heat preservation blanket is as follows:
The invention has the beneficial effects as follows:
1, because special production technique has guaranteed that fibrous residue ball content is low, and Fibre diameter is thin, the tapetum fibrosum softness is skin irritation not, has the good feature of environmental protection;
2, novel inorganic fiber thermal insulation blanket outward appearance is neat, and color is pure white;
3, the conventional fabric width of novel inorganic fiber thermal insulation blanket is 910mm to the maximum, has guaranteed easy construction;
4, novel inorganic fiber thermal insulation blanket belongs to blanket class indefinite form product, can construct according to client's requirement, and safe and simple easy row is without the extra package requirement;
5, heat-insulating property is more superior: very thin fiber, and low slag ball content, fluffy structure is so that tapetum fibrosum under same unit weight condition, form sealed porosity more, less, more even, so heat-insulating property is better;
6, solve the vacancy of the fibrous heat insulator under 450 ~ 800 ℃ the Working environment, both be used for 450-800 ℃ thermal environment, substitute again traditional lagging material and using below 450 ℃.
