The use method of brick of argillaceous heat preservation reachs manufacturing technology

The use method of brick of argillaceous heat preservation
Brick of argillaceous heat preservation not only what early days raw material should use is good, of later period immerse with using also is to have cultured very much.
1: Scarcely of bubble current Cheng can of bubble much. It is the construction plan that combines a worker very, the build by laying bricks or stones of the brick of bubble and worker builds speed photograph be identical.
2: Should make good program ahead of schedule before brick of laid clay heat preservation, because spread,can not stick the effect and 2 construction.
3: Bricklaying the reverse side cannot use big core the material that material board makes metope, be heated sends bricky body to fall off since easy arch.
4: The brick is seamed must stay, and cannot too small, heat bilges cold the principle that shrink, brick of argillaceous heat preservation is in be heated when can expand bricky body, crowded crack liner face.
5: Discover the problem wants to be handled immediately in construction process, after entire store has been stuck, the use effect that the small issue of a bit causes brick of argillaceous heat preservation possibly is bad, want to amend again very troublesome.
6: Hind, serious examination metope wants before construction, discovery has break, of craze should handle appropriate, metope wants to clear carefully.
Reasonable, brick of effective use clay heat preservation, it is better to just can make the life of kiln furnace gets lengthen, use.

Is brick of argillaceous heat preservation calls clay qualitative adiabatic brick again the Al that makes for main raw material with saggar? O? Content is the adiabatic and refractory products of 30%~48% . Its produce craft to use burn oneself out to add content law and bubble way. With saggar, float bead, saggar grog makes raw material, mix into is added bond and curium wood chip, classics burden, mix, shape, dry, firing, make so that bulk density is 0.3~1.3g/cm? product. The crop that sticks brick of earthy heat preservation occupies the half above of adiabatic firebrick total output.

Brick of argillaceous heat preservation manufactures technology
The manufacturing technology with commonly used brick of argillaceous heat preservation is to add float bead burn oneself out adds content way, also can use bubble law technology.

(1) bits of sawdust of raw material bond
Grog of raw material saggar, clay, float bead
Waste liquid of pulp of bond saggar sulphurous acid, vitriolic aluminium, water glass, phosphoric acid reachs phosphate, dextrin, colophony
Diameter of bead of sawdust bits bead should be less than 1~2mm
(2) burden
Product volume density is different, float bead join a quantity to also differ, general wave motion is between 10%~70% , the bulk density of the product is smaller, add a capacity more, fine white of partial clay grog is joined in burden, in order to because float,decrease bead be out of shape the bulk of generation contracts, float to decrease bead dosage, improve semi-manufactured goods intensity and reduce firing and contractive join right amount curium wood chip.
(3) by float bead, the order that curiums wood chip, bond, water, clay reachs clinker fine pink is joined. Mix refine 5`6min, so as to is obtained in order to float bead or curium wood chip is core, bond and clay include outside, outer outside the pug that powder expects. Will float bead, clay of clinker fine pink, union and curium wood chip join inside machine, dry water and bond are added after mixing 2~3min, wet mix 3~4min, the pug with good batch mixing can shape after tired makings 12~24h.
(4) shape
Use handiwork more or machine pressing shapes, machine pressing shapes should use 150~300KN to control bricky machine
(5) dry
The bricky embryo after shaping can use channel desiccator or be in large hole is dry. Bricky embryo because water content is bigger, the entry that submits channel desiccator does not exceed 50 ℃ , outlet temperature does not exceed 150 ℃ . Dry hind the leftover moisture control of bricky embryo is in 2% the following.
(6) loading of kiln and firing
Use side outfit, the requirement is smooth, firm, straight, layer upon layer shop with rice husk, the hand should stay to seam between bricky embryo, height of loading of kiln is in commonly 1.5~1.8m, is bulk density less than 0.6g/cm? goods does not exceed 1.2m, install in place of the low temperature inside kiln. Goods begs kiln Wen Junyun in the stress when side blaze kiln or channel kiln are firing, because float,high fever becomes temperature bead, argillaceous quality reachs product volume density and different.
