Description
Technical field
The present invention relates to a kind of calcium silicate material that useless porcelain powder makes and preparation method thereof that utilizes.
Background technology
Calcium silicate board with microporous is the principal item of calcium silicate material, is used for the High Temperature Furnaces Heating Apparatus heat insulating the earliest.As " in order to improve the shaft kiln clinker yield and quality, being convenient to the raw material coal blending and burning till coal consumption, must strengthen the shaft kiln body insulation with the reduction grog.Common way is, thermal-insulating method in adopting, flame retardant coating, thermal insulation layer total thickness should 〉=650mm, should add 〉=calcium silicate board with microporous or the alumina silicate fiber felt of 60mm near kiln wall place ".Calcium silicate board is general in the world high-grade furred ceiling materials for wall, is the building board of using always in areas such as flourishing Japan, the U.S., West Europe, South East Asia.In China, stipulated that with JC/T564-2000 its name is called calcium silicate board.Though calcium silicate board is introduced into China and produces 15 years of less than, obtains the extensive approval in market with good performance.
The general raw material of making calcium silicate board, mainly be the calcareous raw material (for example: lime, cement etc.) that comprises the about 30-45 weight of solids component %, about 30-45 weight % the silicic acid raw material (for example: original natural silicic acid raw materials such as silica powder, diatomite), and other mixing raw material of the fortifying fibre of about 5-15 weight % (for example: paper pulp fiber, glass fibre etc., in order to strengthen structure) and 10-20 weight %.Above-mentioned raw materials is formed and water blending formation slurry, handled to send into autoclave after the molding box moulding again, can obtain calcium silicate board.
Mostly above-mentioned silicic acid raw material is to come from original natural sandstone, but natural sandstone has a strong impact on the soil conservation and the eubiosis if will be destroyed landform, landforms by overexploitation; In addition, based on the reality that resource is petered out, the exploitation that had that it is forbidden by decree to so just makes the silicic acid raw material of regular grade be difficult to obtain.Therefore, relevant industry is badly in need of seeking the substitute of silicic acid raw material; Particularly, if this silicic acid raw material can be provided by a waste, then, also can reduce production costs except reaching the environmental protection purpose accident that castoff regenerative is utilized.
Waste ceramic often is not recovered utilization, and factory also just uses seldom a part as poor material.But dioxide-containing silica is very high in the waste ceramic powder, contains 65% silicon-dioxide in the architectural pottery approximately, can be used as the silicic acid raw material of producing calcium silicate material.Producer generally all wishes these useless porcelain are made full use of, and reduces production costs, and reduces waste pollution.But, because useless porcelain powder does not have plasticity-substantially, the stupalith plasticity meeting variation that adds useless porcelain powder, easy-formation not, firing temperature is also higher, can only be used for the stopping composition as pottery on a small quantity, consumption is generally below 20%, therefore, still have a large amount of waste old ceramics abandoneds at present, serious environment pollution.
Summary of the invention
Technical problem to be solved by this invention is exactly in order to overcome the deficiency that a large amount of waste old ceramics abandoneds causes serious environment pollution.
Purpose of the present invention can be achieved through the following technical solutions: a kind of calcium silicate material that utilizes useless porcelain powder to make, the raw material that comprises following parts by weight: useless porcelain powder 35-70, other silicic acid raw material 0-35, calcareous raw material 35-55, fortifying fibre 0-15, portland cement 0-10; Wherein, described other silicic acid raw material is one or more in silica powder, diatomite, the mica; Described useless porcelain powder comprises the raw material of following parts by weight: silicon-dioxide 50-75, aluminium sesquioxide 10-30, calcium oxide 2-5, magnesium oxide 2-5, potassium oxide 1-5, sodium oxide 1-5, Vanadium Pentoxide in FLAKES 0-3.Described useless porcelain powder directly obtains from ceramic production technology or breakage, underproof waste ceramic carried out fragmentation, ball milling powder process and gets.
A kind of preparation method who utilizes the calcium silicate material that useless porcelain powder makes may further comprise the steps:
1) preparation of useless porcelain powder: directly from ceramic production technology, obtain or breakage, underproof waste ceramic carried out fragmentation, ball milling powder process and get;
