Description

A kind of foamed ceramic and its production method
Technical field
The invention belongs to building materials manufacturing technology more particularly to a kind of foamed ceramic and its production methods.
Background technique
Foamed ceramic is with clay tailing, potsherd, riverway sludge, and adulterated material etc. is used as primary raw material, and use is advanced The closed pore ceramic material of production technology and foaming technique through high porosity made of high-temperature roasting.This ceramic material presents more Hole honeycomb is suitable for building exterior wall heat preserving, fire-blocking belt, building self-heat conserving cold-heat bridge processing etc..Currently, this foaming pottery Porcelain needs addition foaming agent that moulding material is made to form stomata in process of production, most of also with one in terms of waste utilization A little mud, potsherds etc. in terms of materials cost, are shown although can achieve the various application demands of Environment-friendlyceramic ceramic material So also have can room for promotion, how it is comprehensive turn waste into wealth, be the project for needing to study at this stage.
Summary of the invention
In view of above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a kind of foamed ceramic and its production method, Without foaming agent, so that smelting waste and clay is formed hydrate, form more stable crystal state, improve foamed ceramic each side The performance in face.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
The present invention is a kind of foamed ceramic and its production method, and score meter by weight includes following components: smelting waste 12-14 Part, 16-20 parts of clay, 3-5 parts of sludge, 2-4 parts of water；
Specific production stage are as follows:
(1) clay adds water softening stand-by；
(2) by smelting waste ball milling dusting, 180-250 mesh is crossed, the waste residue of dusting is rubbed up with 60-80 DEG C of state with sludge；
(3) intermittent addition softens clay during rubbing up, until clay addition finishes, entirely rubs up time control and exists Within 40min；
(4) the mixture pressing mold molding after rubbing up, forms using 1000-1200 DEG C of high-temperature roasting.
A kind of foamed ceramic of the invention and its production method, score meter by weight includes following components: smelting waste 13 Part, 18 parts of clay, 4 parts of sludge, 3 parts of water.
Smelting waste of the invention is the waste residue comprising Determination of multiple metal elements, and sludge is river sludge or vegetation sludge.
The present invention is using waste residue and sludge as integrating materials, by clay plasticity, mainly generates gas by organic sludge, Clay is added during rubbing up forms stomata, and clay and waste residue metal form hydrate, gained foaming at high temperature under high pressure Ceramics are with the porous material of crystal package regulus, whether in the rigidity of structure, crushing resistance, flexural strength and durability etc. Aspect, which has, significantly to be promoted.
Specific embodiment:
The present invention is described in detail with reference to embodiments.
Embodiment 1:
A kind of foamed ceramic of the invention and its production method, score meter by weight includes following components: 12 parts of smelting waste, glutinous Native 16 parts, 5 parts of sludge, 2 parts of water.Add water softening stand-by clay in proportion, by smelting waste ball milling dusting, crosses 200 meshes, powder The waste residue of change is rubbed up with 60 DEG C of state with sludge, and intermittent addition softens clay during rubbing up, until clay adds It finishes, entirely rubs up time control within 40min.Mixture pressing mold molding after rubbing up, using 1000 DEG C of high-temperature roastings Molding.
Embodiment 2:
A kind of foamed ceramic of the invention and its production method, score meter by weight includes following components: 13 parts of smelting waste, glutinous Native 18 parts, 4 parts of sludge, 3 parts of water.Add water softening stand-by clay in proportion, by smelting waste ball milling dusting, crosses 180 meshes, powder The waste residue of change is rubbed up with 70 DEG C of state with sludge, and intermittent addition softens clay during rubbing up, until clay adds It finishes, entirely rubs up time control within 40min.Mixture pressing mold molding after rubbing up, using 1100 DEG C of high-temperature roastings Molding.
Embodiment 3:
A kind of foamed ceramic of the invention and its production method, score meter by weight includes following components: 14 parts of smelting waste, glutinous Native 16 parts, 3 parts of sludge, 2 parts of water；Add water softening stand-by clay in proportion, by smelting waste ball milling dusting, crosses 250 meshes, powder The waste residue of change is rubbed up with 80 DEG C of state with sludge, and intermittent addition softens clay during rubbing up, until clay adds It finishes, entirely rubs up time control within 40min.Mixture pressing mold molding after rubbing up, using 1200 DEG C of high-temperature roastings Molding.
Embodiment 4:
A kind of foamed ceramic of the invention and its production method, score meter by weight includes following components: 12 parts of smelting waste, glutinous Native 20 parts, 5 parts of sludge, 4 parts of water；Add water softening stand-by clay in proportion, by smelting waste ball milling dusting, crosses 220 meshes, powder The waste residue of change is rubbed up with 75 DEG C of state with sludge, and intermittent addition softens clay during rubbing up, until clay adds It finishes, entirely rubs up time control within 40min.Mixture pressing mold molding after rubbing up, using 1150 DEG C of high-temperature roastings Molding.
In above-described embodiment, smelting waste is the waste residue comprising Determination of multiple metal elements, and sludge is that river sludge or vegetation are dirty Mud.
Foamed ceramic obtained by above-described embodiment is tested for the property, specific as shown in table 1.
Compression strength Tensile strength Thermal coefficient Dry density
Embodiment 1 0.22Mpa 0.19Mpa 0.038W/m·K 122kg/m3
Embodiment 2 0.23Mpa 0.21Mpa 0.036W/m·K 125kg/m3
