Abstract
The invention discloses a foaming ceramic thermal insulation pipe. According to the foaming ceramic thermal insulation pipe, a foaming ceramic layer is taken as an inner layer, a metal tube is taken as a middle layer, a foaming ceramic layer is taken as an outer layer, and the surface of the foaming ceramic is similar to a common outer wall tile, so that the foaming ceramic thermal insulation pipe is low in water absorption rate, keeps out of wind and rain, and is pollution-free. The foaming ceramic thermal insulation pipe has the advantages of being high in thermal insulation efficiency and long in service, greatly reducing the resource waste, and being used for chemical industry and petrifaction and also used for conveying gas and liquid needing thermal insulation in steam conveying industry.
Description
Technical field
The present invention relates to pipe insulation heat-insulating technique field, specifically belong to a kind of foamed ceramic thermal insulation pipe that is used for pipe insulation and preparation method thereof.
Background technique
Existing pipe insulation is protected with asbestos usually and is wrapped up in metallic conduit, and what have also wraps up the aluminium skin again outside asbestos, proved that at present asbestos have public hazards, and asbestos can be carcinogenic; And the aluminium skin is prone to oxidation, and under rainy or wet environment, the asbestos suction causes protected metallic conduit oxidation, transportation of substances to leak, and causes waste or forms public hazards, and this type of pipeline usually needs periodic maintenance, replacing, causes the social resources wave to give up.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing technology, the purpose of this invention is to provide a kind of foamed ceramic thermal insulation pipe and preparation method thereof.
The objective of the invention is to realize through following technical proposals: the foamed ceramic thermal insulation pipe is that internal layer, metal tube are that mesosphere, foamed ceramic layer are outer the composition by the foamed ceramic layer.
The thickness of said internal layer foamed ceramic layer is 1～3mm.
The thickness of the metal tube in said mesosphere is 2～5mm.
The thickness of said outer foamed ceramic layer is 10～50mm.
The preparation method of foamed ceramic thermal insulation pipe is: with injector and etc. static pressure compression moulding and the foamed ceramic raw material is emitted as hollow tube according to required duct size, it is the foamed ceramic hollow tube below 0.5～0.8 g/cm3, the transmission of heat 0.2 W/m .k that hollow tube becomes proportion through 1160-1200 ℃ high-temperature firing; Again the foamed ceramic hollow tube is enclosed within corresponding metal pipeline internal layer and skin respectively, is foamed ceramic thermal insulation pipe finished product.
The invention has the beneficial effects as follows: the surface of its foamed ceramic is like general exterior wall ceramic tile, and foaming formation closed pore insulation directly parcel pipeline water absorption rate is not afraid of wind and weather below 0.5, and is nuisanceless, more can enter a protection surface at the surface glazing material of foamed ceramic; The internal layer of its foamed ceramic makes inner-walls of duct seamless, and the insulating efficiency of foamed ceramic thermal insulation pipe of the present invention is high, long service life, and it is useless significantly to have reduced the resource wave.
Below in conjunction with accompanying drawing and body mode of execution thereof the present invention is done further explain.

Referring to Fig. 1, foamed ceramic thermal insulation pipe of the present invention is that the metal tube of internal layer 1, wall thickness 2～5mm is that the foamed ceramic layer of mesosphere 2, wall thickness 10～50mm is outer 3 with the foamed ceramic layer of wall thickness 1～3mm.
The optimum thickness of said internal layer 1 foamed ceramic layer is 1mm;
The optimum thickness of said mesosphere 2 metal tubes is 3mm;
The optimum thickness of said outer 3 foamed ceramic layers is 20mm.
As further improvement of the present invention, on the surface of outer 3 foamed ceramic layers, being coated with to carry out has the glaze layer, can further protect this thermal insulation pipe surface.
The preparation method of foamed ceramic thermal insulation pipe is: with injector and etc. static pressure compression moulding and the foamed ceramic raw material is emitted as hollow tube according to required duct size, it is the foamed ceramic hollow tube below 0.5 g/cm3, the transmission of heat 0.2 W/m .k that hollow tube becomes proportion through 1200 ℃ high-temperature firing; Again the foamed ceramic hollow tube is enclosed within corresponding metal inner tube layer and skin respectively, is foamed ceramic thermal insulation pipe finished product.
The insulating efficiency of foamed ceramic insulating tube of the present invention is high, and long service life can be used for chemical industry, petrochemical industry and steam and carries the needs insulation gas of industry, the conveying of liquid.
