Abstract
The utility model discloses a light quality silicate composite thermo-insulating shell. According to thermo-insulating requirements of thermo equipment for users, thermo insulating layers with different thicknesses are designed. As required, two or more multiple layers can be provided, which are integrated in an organically composite way by magnesium silicate paints and aluminium silicate fibre blankets or superfine fiber blankets in proper of 1: 1-5. The light quality silicate composite thermo-insulating shell is provided with a dual structure of a laminar inner layer and a cellular outer layer. The light quality silicate composite thermo-insulating shell has the advantages of lower thermo conductivity coefficient, beautiful appearance, convenient construction, time saving, stable thermo conductivity and visible energy saving. Compared with the similar products, the insulating layer thickness is decreased by 20-25% and the cost of thermo insulating material is lowered by 25-30%.
Description
The utility model relates to a kind of lightweight silicate complex heat-preservation shell that Thermal Equipment is made heat-insulation layer that is used in.
At present, most insulation materials that still adopt the single type structure in the Thermal Equipment insulation.As alumina silicate fibre blanket, felt, ultra-fine fibre glass blanket, felt, magnesium silicate coating, mineral wool, expanded perlite etc.And alumina silicate fibre blanket, felt are having a lot of weak points in using separately, and (γ) is lower for thermal conductivity factor under the normal temperature, but along with the Thermal Equipment temperature raises, it is big that thermal conductivity factor rising amplitude becomes, heat dissipation capacity increases thereupon, and heat-insulating property descends, thermal conductance instability under middle and high temperature condition.Because of uneven, appearance is too fat to move not attractive in appearance, to the more difficult construction of special-shaped Thermal Equipment when using this material separately simultaneously.
Magnesium silicate coating is a kind of emerging insulation material, and more stable at its thermal conductivity factor of medium and high temperature section, amplitude of variation is little, but its thermal conductivity factor is higher at normal temperatures, uses its cost higher separately, and speed of application is slow.
More harm than good to make heat-insulation layer with single insulation material in a word, and the cost height, heat utilization efficiency is low, heat-insulating property is poor.
The patent No. 88202305.5 " aluminium silicate fiber peacekeeping mineral wool complex heat-preservation band " is exactly a kind of with surface layer, the heat-insulation layer that mineral wool, alumina silicate fibre are combined into one, and it has the hot side performance of alumina silicate fibre material, but its cost is low, has improved heat utilization efficiency.
The purpose of this utility model is to provide a kind of lightweight silicate complex heat-preservation shell, the advantage that had both kept former formation silicate composition, have the thermal conductivity factor lower again than orthosilicate insulation material, improved the heat energy utilization rate, saved the energy, shortening engineering time, the 25-30% that reduces cost, and outer surface neat appearance.
The utility model is achieved in that by the compound insulation cladding of alumina silicate fibre material existing organically the stickup in the ratio of 1:1-5 by magnesium silicate coating and alumina silicate fibre blanket, felt or ultra-fine fibre glass blanket, felt is combined into whole lightweight silicate complex heat-preservation shell.

Fig. 2. many composite beds compound cross-section schematic diagram.
Fig. 3. many composite beds compound cross-section schematic diagram.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Insulation requirement according to user's Thermal Equipment, be designed to the heat-insulation layer of different-thickness, proportionate relationship (thickness than) batching of magnesium silicate coating (4) and alumina silicate fibre blanket, felt (2) (or ultra-fine fibre glass blanket, felt (2) ' be mainly used on the lower Thermal Equipment of temperature and use, for example below 300 ℃) being pressed 1:1-5 is compound.Below each scheme all no longer repeat in this ratio.
Factory produces in batches: alumina silicate fibre blanket, felt (2) or ultra-fine fibre glass blanket, felt (2) ' be tiled on the shaping mould as internal layer, above again magnesium silicate coating (4) evenly being covered, smooth with artificial pressurization, dry rear demoulding the complex heat-preservation shell, be sleeved on the Thermal Equipment and can use.
Site operation: as shown in Figure 1 with alumina silicate fibre blanket, felt (2) or ultra-fine fibre glass blanket, felt (2) ' be banded in the pipeline (1) of Thermal Equipment upward as internal layer with galvanized iron wire (3), smear again magnesium silicate coating (3) to design thickness as skin, dry back the complex heat-preservation shell.
Can adopt alumina silicate fibre blanket felt (2) or ultra-fine fibre glass blanket felt (2) ' be banded in Thermal Equipment pipeline (1) with galvanized iron wire (3) to go up as internal layer, pre-formed magnesium silicate coating (4) again, as cover after the two semicircle dryings alumina silicate fibre blanket, felt (2) or ultra-fine fibre glass blanket, felt (2) ' on, with galvanized iron wire (3) two semicircles are tied up firmly, appearance smear again the dry back of skim magnesium silicate coating (4) the complex heat-preservation shell.
Can be made into tubulose, tabular and other various abnormity according to user's needs complex heat-preservation shell.
Said structure is a composite bed.According to user's needs, need the heat-insulation layer of thickness more than 10 centimetres greater than 500 millimeters large-scale Thermal Equipment pipeline at diameter.For reducing volume, but reach same heat insulation effect again, just need to adopt alumina silicate fibre blanket, felt (2) or ultra-fine fibre glass blanket, felt (2) ' with magnesium silicate coating (4) at interval, the complex heat-preservation shell of repetition, compound secondary and the many composite beds of the above formation of secondary.Shown in Fig. 2,3, behind first composite bed, firmly carry out the construction of second composite bed again with galvanized iron wire net (5) wrapping.Or in a composite bed external application of outermost galvanized iron wire net (5) wrapping firmly, smear skim magnesium silicate coating (4) in appearance again lead wire net (5) is covered.
The utility model is compared with prior art: this insulation cladding has internal layer and is stratiform, outerly is the dual structure of micropore, and namely the inner fiber layer structure has lower thermal conductivity factor with respect to cladding material, and outer field microcellular structure has preferably thermal storage performance. Therefore its joint product has lower thermal conductivity factor, generally under the hot side mean temperature is 350 ℃ condition, its thermal conductivity factor is 0.087-0.089 watt/meter. kilocalorie, than the alumina silicate fibre blanket of single type structure, the thermal conductivity factor γ of felt=0.1014 watt/meter. kilocalorie low 0.0144 watt/meter. kilocalorie, than the thermal conductivity factor γ of magnesium silicate coating=0.114 watt/meter. kilocalorie low 0.027 watt/meter. kilocalorie. Maximum operation (service) temperature 800-900 ℃, minimum-25 ℃ of scope of applications are extensive, profile is neat and artistic, and thermal conductance is stable, easy construction, compared with similar products, insulation layer thickness can reduce 20-25% and save insulation material expense 25-30%, and cost is lower, saving of work and time about 1/3, every square metre can be reduced dissipated heat 30-40 kcal/h. and degree, energy-saving effect is remarkable.
