Abstract
The invention discloses a production method of an aluminum silicate inorganic fiberboard. In the invention, water, instead of organic fiber lubricant, is used as fiber lubricant. The invention can produce the aluminum silicate fiberboard without using any organic raw material, and ensures the product quality.
Description
Technical field
the present invention relates to the aluminosilicate fiberboard production field, especially a kind of pure aluminium silicate inorganic fibre plate producing process.
Background technology
produce the producer of PDP in the PDP firing furnace, need a large amount of uses not contain organic inorganic refractory fiber plate.At present, domestic also have at production 1260 inorganic fiberboards, but in its main raw material and the technology; All there is organism to sneak into; Adopt the mode of afterwards burning till to remove organism wherein, remove, still have part residual but this mode can't guarantee organism 100%; In the PDP of high request industry, still can cause negative impact to product quality.The main path that organism is sneaked into is: use alumina silicate fibre blanket to be raw material.Aluminosilicate fiber cotton is in winding-up or get rid of in the production technique of silk, all can use fiber lubricant, so that pinprick becomes blanket, and then burns till through the moulding stove, fiber lubricant is removed, but often removed unclean.Tapetum fibrosum is pulverized the production that is used for inorganic fiberboard, and the residual fiber lubricant that burns incompletely can cause negative impact, and the use of fiber lubricant and moulding stove has caused the rising of cost.In the production process of wad, need tapetum fibrosum be mashed pulping, add organic adhesive and inorganic adhesive then, through mould molding.The organic adhesive that wherein adds is still often unlikely to remove thorough finally through burning till removal.
Summary of the invention
the present invention seeks to: a kind of method of not using the aluminosilicate fiberboard of any organic raw material production is provided.
Technical scheme of the present invention is: a kind of pure aluminium silicate inorganic fibre plate producing process, it is characterized in that, and may further comprise the steps:
(1) raw material cooperates: aluminum oxide and silicon oxide cooperate according to a certain percentage, guarantee that aluminum oxide proportion accounts within the 45%-50%, and both total contents are more than 99%;
(2) resistance furnace fusion: under the temperature about 2600 degree, raw material is carried out fusion;
(3) jet fibre: do not use the organic fibre lubricant, make water, flow 100-150L/ hour as fiber lubricant;
(4) cellucotton is pulverized: use crusher to pulverize frequency 30-50HZ, mesh plate bore dia 10-30mm;
(5) slurry cooperates: silicon sol and water are cooperated according to the 1:2 ratio, drop into the fiber material of 3-5% then, stir;
(6) vacuum forming: adjustment pressure, be shaped to 0.03-0.05mpa, dewatering is 0.020-0.025mpa;
(7) freezing: with product in refrigeration chamber freezing 12-24 hour, design temperature was-10 ℃ ~-5 ℃;
(8) drying: in drying room dry 12-72 hour.
are not used organic adhesive fully in moulding process, silicon sol and water are cooperated in the 1:2 ratio, form the solution with certain viscosity through stirring; Again wherein with the fiber input; Stir and generate fiber pulp, make the solution and the fiber pulp thorough mixing of inorganic adhesive, through the amount of adjustment fiber; Reach the fiber concentration of 3-5%, become plate through vacuum forming afterwards.Since the relative organic bonding of inorganic adhesive slightly a little less than; Regulated the negative pressure of vacuum pump, be shaped to 0.05mp, dewatering is 0.025mp; Let patrix push down product when dewatering again; With compare the moisture that stays about 10% at ordinary times more, control vacuum negative pressure then it slowly removed, guaranteed product inside can not occur the be full of cracks.Pure aluminium silicate inorganic fiberboard hardness of the present invention is greater than 70, and folding strength is greater than 0.49Mpa.
Advantage of the present invention is:
The aluminosilicate fiberboard that
can not use any organic raw material to produce has guaranteed the quality of product, and this product is under 24 hours conditions of 1100 degree heating; Mistake rate≤1 is burnt, density>=270kg/m3 in shrinking percentage≤3.0; Folding strength>=0.49MPa, surface hardness>=70.
