Abstract
The invention discloses a light shale brick utilizing waste molasses as a pore-forming agent and a production method. The light shale brick consists of raw materials according to the following weight percents: 75%-85% of shale, 15%-25% of other auxiliary materials, and waste molasses water at the temperature of 45-55 DEG C with the volume ratio of 15%-20%. The production method comprises the steps of: grinding the shale of the raw materials into powder capable of passing through an 80-mesh sieve, evenly mixing with the auxiliary materials and then adding the waste molasses water, stirring evenly, carrying out vacuum extrusion forming, cutting into billets, drying the billets, placing under the condition of 950-1150 DEG C for roasting, and maintaining for 8-12 hours to obtain the light shale brick. The light shale brick and the production method have the advantages that the waste molasses has the effect of binding particles in a blank stage so as to limit the emergence and development of cracks in a drying stage; organic matter in the molasses and a part of the auxiliary materials are burnt down in a roasting stage, and a large number of micropores are formed in the brick, so that the light shale brick has better performance such as heat preservation, heat insulation, fire prevention, cracking prevention, sound insulation and the like, the dead weight is significantly reduced, and the light shale brick has excellent anchorage performance, low cost, light dead weight and convenience in construction, and can satisfy the need of secondary decoration of a building.
Description
Technical field
The present invention relates to the disposal and utilization of waste material from sugar refinery molasses, be exactly specifically the performances such as a kind of lightweight, insulation, heat insulation, fire prevention, anti-cracking, sound insulation utilize light shale brick and the production method of waste molasses as pore former.
Background technology
In 200510022384.8 patent document, produce shale brick Micropore Agent used and be mainly polystyrene and expanded perlite granule, it is safe that the solid form of polystyrene uses, atoxic.But EPS particle will give out pentane steam in storage process.Pentane very easily fires, and can form explosive mixture with air, and heating polystyrene type polymkeric substance can discharge styrene monomer, and vinylbenzene is a kind of material of danger, and Polystyrene powder can stimulate respiratory tract and skin.And high this of the price of pearlstone just increased cost.So utilize waste molasses to there is the advantages such as raw material is sufficient, cost is low, pollution-free, toxicological harmless as the pore former of light shale brick.
Common shale brick and production method thereof are that follow procedure carries out roasting and makes by after shale pulverizing, moulding.Common shale brick is from great, and heat insulation property is poor, and production process energy consumption is large, not environmental protection.
Summary of the invention
It is good that object of the present invention is just to provide a kind of heat insulation property, and from heavy and light, and the energy-conservation waste molasses that utilizes utilizes light shale brick and the production method of waste molasses as pore former as pore former.
Solution of the present invention is such:
A kind of light shale brick of waste molasses as pore former that utilize, formed by the following raw material that contains weight percent: shale 75%-85%, other auxiliary material 15%-25%, temperature are the waste molasses water that 45-55 ℃ and volume ratio are 15% ~ 20%, the shale powder of above-mentioned raw materials was broken to 80 mesh sieves, after mixing with auxiliary material, add molasses syrup, stir, through extrusion under vacuum, cut into base, base is dried, put into and under 950 ℃ ~ 1150 ℃ conditions, carry out roasting and keep making for 8 ~ 12 hours.
Technical scheme also comprises more specifically: described auxiliary material is to adopt unslaked lime and aluminium powder to mix, and between the two auxiliary material, mass percent is: unslaked lime 87.5% ~ 90%, aluminium powder 10% ~ 12.5%.
Further: described auxiliary material is to adopt unslaked lime and iron powder to mix, and between the two auxiliary material, mass percent is respectively: unslaked lime 80% ~ 85%, iron powder 15% ~ 20%.
Further: described waste molasses is the mother liquor of crystallize out again after the treating sucrose of sugar refinery, and described mother liquor is thick more than 80% containing solid substance.
Utilize the production method of waste molasses as the light shale brick of pore former, comprise step:
(1), material preparation step: will mainly be made by the following raw material that contains mass ratio: shale 75%-85%, other auxiliary material 15%-25%, described auxiliary material is to adopt unslaked lime and aluminium powder to mix, its mass percent is: unslaked lime 87.5% ~ 90%, aluminium powder 10% ~ 12.5% or described auxiliary material are to adopt unslaked lime and iron powder to mix, its mass percent is: unslaked lime 80% ~ 85%, iron powder 15% ~ 20%, and above-mentioned raw materials fragmentation is crossed to 80 mesh sieves and mix in mass ratio;
(2), waste molasses water preparation steps: adding water to make volume ratio in waste material molasses is 15% ~ 20% waste molasses water, and to be heated to temperature be 45-55 ℃;
(3), produce mixture step: the waste molasses water that raw material prepared by step (1) adds step (2) to produce stirs, and stirs and leaves standstill 1 hour ~ 1.5 hours, makes base, and base is dried;
(4), forming step: wet feed extrusion molding is made to adobe, carry out roasting and keep 8 ~ 12 hours under 950 ℃ ~ 1150 ℃ conditions.
Advantage of the present invention is in shale powder, to add other auxiliary materials and waste molasses water, and moulding base, sinters brick into.Play the effect of bonded particulate at base substrate stage waste molasses, certain restriction has been played in the generation in the crack to drying stage and development; Due to the existence of viscosity, the consumption of moulding moisture can be reduced in addition, also time of drying can be shortened.In the roasting stage, in molasses, organic and partial supplementary material burn totally, forms a large amount of micropores in brick, therefore has the performances such as good insulation, heat insulation, fire prevention, anti-cracking, sound insulation, and deadweight reduction greatly, is specially adapted to the non-bearing wall body part of building; Simultaneously shale brick of the present invention, compared with other non-lbearing wall materials, has good anchoring property, with low cost, and from heavy and light, easy construction, can meet the needs of buildings secondary decoration.
