Abstract
This invention is how to produce the pottery fibreboard and its technology. They made of pressed poly layer pottery fibreboard. In the middle of two layers has some binders, to keep thickness of binders 0.5-3mm. There are two methods to produce them. The one is semi-continued production: every pottery fibro board which are according to continuously produced after cut, pressed, and in the middle between them there are binders and fillers, then pressed them under the press machine 10-20 minutes, and heated them into oven to stove keep 40-60deg.C them make it up. The other method is continuous production; after the pottery fibreboard is formed put binder milk solution spread on the wet paper. Then add the power filler put the wet paper into oven to stove 40-60deg.C till it semidry rounded them by machine, pressed, till whole dry, then the pottery fibreboard is finished.
Description
Technical field
Ceramic beaverboard and production technology thereof belong to the technical field of high-temperature fibre plate, relate in particular to the ceramic fibre plate technique.
Background technology
Ceramic fibre is a kind of alumina silicate series fiber, belongs to the refractory fibre category.Its main body composition is aluminium oxide (Al
2O
3) and silica (SiO
2).Ceramic fibre is divided into noncrystalline ceramic fibre and crystalline ceramic fiber two big classes by microstructure, distinguishes and press temperature resistant grade, is followed successively by from low to high: common alumina silicate fibre, high alumina silicate fiber, contain chromium (Cr
2O
3) alumina silicate fibre, contain zirconium (ZrO
2) alumina silicate fibre, polycrystalline mullite fibre and polycrystalline alumina fiber etc.The long-term serviceability temperature of ceramic fibre is generally more than 1000 ℃.It not only has the good heat-insulating properties of traditional inorfil such as asbestos, glass wool, mineral wool, and it can at high temperature use for a long time, can replace traditional heavy refractory material, so in recent years, worldwide this technical development is very fast.About 200,000 tons of world's ceramic fibre annual production at present, annual growth 10-15%.
The goods that derived by ceramic fibre have ceramic fibre needle punched blanket, felt, wet felt, plate, module, paper, fabric etc.Wherein, ceramic beaverboard has excellent mechanical property and wind erosion-resistance performance, and is of many uses.For example in steel industry, gasket seal when can be used for being connected between the repairing, high-temperature component in the location of elevated-temperature seal, continuous casting steel machine between continuous casting steel machine slide gate nozzle system sliding plate brick and the nozzle brick or spray of molten steel splash-back, inner lining of furnace, baking oven back boxing, kiln slit or the like.
United States Patent (USP) 4389282, name is called " ceramic beaverboard ", and United States Patent (USP) 5273821, and name is called the ceramic beaverboard of mentioning in " high-strength ceramic fiberboard ", all adopts vacuum forming technique to make.Be about to ceramic fibre raw material, binding agent emulsion and mixing of filler, after vacuum forming, dry and make.This production method, production efficiency is low.Its product strength is poor, and density is little, impact resistance, scratch-resistant performance inequality.Such sheet material very easily forms die-cut breach when die-cut cutting out, be difficult to guarantee the precision of die-cut product size, and waste is big.So it can not satisfy the instructions for use of high accuracy, high temperature resistant, rub resistance industrial materials.
Summary of the invention
The objective of the invention is to: at the problem of above-mentioned existence, propose brand-new ceramic beaverboard of a kind of structure and production technology thereof, it can effectively increase intensity, density, shock resistance, the scratch-resistant performance of ceramic beaverboard and enhance productivity,
Technical solution of the present invention is: it is 1 stacked by the multi-layer ceramics fibrous paper, add and be pressed into, and is provided with adhesive layer 2 between per two layers of ceramic fiber paper 1.The thickness of ceramic fiber paper 1 is 0.2-1.0mm..Adhesive layer 2 thickness between two layers of ceramic fiber paper are 0.5-3.0mm.
Its production technology has semicontinuous working system and continuous working system.The processing step of semicontinuous working system is as follows:
1) with the ceramic fibre is raw material, adopts the wet method continuous forming process to make ceramic fiber paper;
2) ceramic fiber paper is carried out cutting, stacked, and between two layers of adjacent paper, brush certain thickness binding agent, filler mixture, form adhesive layer 2;
3) on hydraulic press, pressurizeed 10-20 minute;
4) put that 40-60 ℃ of oven dry makes in the baking oven.
The processing step of working system is as follows continuously:
1) with the ceramic fibre is raw material, adopts the wet method continuous forming process to make ceramic fiber paper;
2) on l Water Paper, apply binding agent, remove unnecessary binding agent, and apply the fleut mixture by Negative pressure machine;
3) l Water Paper being put in the baking oven 40-60 ℃ dries by the fire to 3-5 minute and is half-dried to ceramic fiber paper;
4) mechanical rolling is taken off after the cutting to desired thickness, moves on the hydraulic press;
5) on hydraulic press, pressurizeed 10-20 minute;
6) put that 40-60 ℃ of oven dry makes in the baking oven.In above-mentioned two kinds of production technologies, ceramic fibre raw fiber diameter is 1-5 μ m; Fibre length is 10-100mm.
The ceramic fibre laminated board that the present invention makes, owing to be to be pressed into through height with the ceramic fiber paper of sandwich construction densification adding binding agent, filler, therefore its density height, tension, strong shock resistance, scratch-resistant performance are good, have certain flexibility again, be particularly suitable for the reparation as the sealing between the high-temperature component, kiln slit, aspects such as the backing use of refractory material.
