According to frit kiln the development course of insulation material, can divide the traditional insulation material that already developed for early and the new-style frit kiln that in recent years research and development comes out insulation material. Insulation material basically includes traditional frit cave dwelling: Brick of light qualitative clay, siliceous aluminous beaverboard, small qualitative siliceous calcareous plate, light qualitative silica brick, high temperature resistant the new-style accept such as coating insulation material basically includes rice frit kiln to blast off blanket of heat preservation of rice of accept of silicon of accept of thermal insulation board of small hole of class of rice of material of high-powered fiber spray, accept, titanium, high rate. Traditional insulation material is more familiar, here no longer give uncecessary details, and emphasize will introduce new-style insulation material.
1, material of high-powered fiber spray
Basically come loose with Yu Rong kiln hot side is outer, product heat preservation and sealed performance are excellent, effect of energy-saving environmental protection is distinct, if its performance data expresses 1 to show.
Express performance data of data of spray of 1 high-powered fiber
2, thermal insulation board of small hole of accept rice class
Accept rice class is empty thermal insulation board is the new material that new high-tech technology makes, it is to use special inorganic and fireproof powder, formed super air hole of the smile, its coefficient of thermal conductivity is even smaller than dormant air, if performance data expresses 2 to show. This product is board shape, can combine PE of the form such as cloth of plastic film, aluminum foil, fiber outside covering layer material. The working principle of this product:
(Is 1) conducted conduct heat: ? Arrogate to oneself allows paragraph of ⑾ to mound handkerchief of Jia very hot Jian:
(Does 2) convection pass hot: ? Arrogate to oneself allows?0 Nm of arrogant of plating bright. Hot movement of dormant air normal temperature is average and free Cheng 60nm, air element is chained and cannot do convection to conduct heat, make hot to circulating effect very little;
(Does 3) radiate conduct heat: ?
Express performance data of thermal insulation board of small hole of class of 2 accept rice
3, blanket of heat preservation of rice of accept of gel of gas of titanium accept silicon
Use the 2 oxidation silicon that contains titanium the structure of cavity of special offer rice of successive material interior, if the graph is shown 1 times, the compositive characteristic: of material? Phlegmy where arrogate to oneself allows miscellaneous sand of of palm of Kuang of ∮ of ⑿ of Peng of Qiang of Qian of ⑻ Li of ⒏ of calf seed ā is violet block comfortable channel Mei up to identify stool to stop Wu already like that place of? of Bin of the sliding weight of a steelyard is shown, this kinds of product basically is layer of blanket of siliceous aluminous fiber, efficient heat preservation to enrage gel layer for many times compound form, its performance data is as follows:
(1) coefficient of thermal conductivity is low, 0.012~0.016 W/(m•K);
(2) A1 class is not lighted, and; is not decomposed below high temperature
(Range of 3) use temperature is wide (0~1 050 ℃ ) ;
(The compression with extremely strong 4) , shock-proof, fight adjustable wait for function;
(5) does not suck tide, not ageing, use heat preservation function for a long time not to drop;
(6) heats up minimum of coefficient of expansion, avoid heat to bilge cold shrink appear rupture fault;
(7) installation volume is minor, save a space, reduce installation and carriage cost; significantly
(8) is extremely light-duty and flexible material, construction is extremely handy, random cuts out, go all out stick.

4, high emissive rate is energy-saving material
The heat preservation mechanism of traditional insulation material is to pass heat insolation to reduce quantity of heat to deliver, use at the cold face of fireproof material commonly, and high emissive rate is energy-saving material applies on frit kiln is spray Yu Rong kiln comes loose hot side wall, can increasing while the heat radiation inside kiln is measured, reduce the quantity of heat that vitreous fluid delivers external. Such not only the quantity of heat of the prediction of a person's luck in a given year in the fireproof material that reduces above of vitreous fluid face, more the quantity of heat that in reducing flue gas greatly, takes away. Its performance data is as follows:
(1) applies to fireproof material surface, the ply after spray, solidify has 0.1 ~0.2 Mm only.
(Performance of 2) heatproof shake is strong, extend a gender good, but as spray matrix expand and extend, come off with what quits thermal shock arises force.
(3) is able to bear or endure soda acid corrodes ability tall, apply to the complex combustion atmosphere inside vitreous dissolve kiln.
(Data of high emissive rate distinguishs 4) at a few kinds of afore-mentioned insulation material, itself is not a kind of insulation material. Absorb radiation and convective quantity of heat below high temperature condition however, and will among them 95% again radiation goes out, make quantity of heat OK circulate in frit kiln interior.
(5) launchs coefficient to keep changeless between 0.85 ~0.95 below high temperature, and the emissive coefficient that general and fireproof material issues in high temperature condition has 0.2 ~0.3 only between.
