Description
Technical field
The invention belongs to environment-friendly building materials technical fields, and in particular to a kind of ring that useless medical gypsum manufacture is recycled using orthopaedics
It protects non-burning brick.
Background technology
The orthopaedics of hospital needs to accept the patient of a large amount of bone fractures for medical treatment, usually requires to use medical gypsum during patient's synthetism
It being fixed, removes gypsum again after bone healing, gypsum would generally be handled after dismounting as solid waste, and
Since the gypsum that hospital uses belongs to Biohazard Waste, wherein may carry with directly or indirectly infectious, toxicity and its
The substance of his harmfulness belongs to the product not directly recycled, hospital in the rubbish separating treatment relevant laws and regulations in China
The mode filled for this solid waste generally use high temperature incineration and dell is handled, this not only pollutes the environment, also
It is the huge waste to resource.
Invention content
In view of the above problems, the purpose of the present invention is to provide a kind of environmental protection that useless medical gypsum manufacture is recycled using orthopaedics
Non-burning brick, the technique of the invention can carry out harmless processing and recycling to doctor's waste gypsum, both avoid the pollution to environment,
Also achieve efficiently using for resource.
A kind of environment-friendly baking-free bricks that useless medical gypsum manufacture is recycled using orthopaedics, including step is produced by below：
（1）Dispensing material：According to mass fraction, 60-70 parts of waste gypsum powder, 15-20 parts of red mud, 6-7 parts of yellow sand, aggregate 15- are cured
20 parts, 5-10 parts of lime, 15-25 parts of cement, each dispensing is ready to, is sent in blender and mixes thoroughly, so by 6-8 parts of curing agent
Add water into blender according to the ratio of ratio of mud 0.21-0.23 afterwards, stir 10-15min, it is spare to obtain required adobe material.
（2）Green brick forming：Adobe material is sent in the compacting tool set of brick machine, is pressed into the pressure of 20-25MPa
Type stands 2-3h naturally after compacting.
（3）Dehydration forming：Then adobe is sent in molding kettle and carries out dehydration and drying molding, adobe is in molding kettle
Drying is divided into three phases；The temperature of first stage remains 120-130 DEG C, and air humidity was controlled as 60-70%, drying time
For 0.5-2h, the temperature of second stage remains 140-160 DEG C, and air humidity is controlled as 40-60%, drying time 3-4h, third
The temperature in stage remains 160-180 DEG C, and air humidity control is 10-20%, drying time 0.5-1h.
（4）Recrystallization maintenance：Adobe after dehydration forming out of molding kettle is taken out, is cooled to room in its natural state
Then adobe is impregnated 1-2h by temperature in clear water, adobe is impregnated with completely by clear water, and recrystallization process is completed in adobe, then by brick
Base takes out the natural curing under the normal temperature state of aeration-drying, obtains required environment-friendly baking-free bricks.
In the present invention, doctor's barren rock creme is to recycle the plaster mold that hospital orthopedics are removed, and plaster mold is roasted by crushing, high temperature
It burns and grinding obtains powder, high-temperature roasting carries out in sintering oven, and temperature is 1300-1350 DEG C, and the mesh number of obtained powder is
150-200 mesh.
Aggregate is that the broken ceramics of recycling pass through crushing, screening, and obtained grain size is in the ceramic particle of 3-4mm.
Preferably, containing magnesia, aluminum sulfate, sodium phosphate and green vitriol in curing agent, four mass ratio is 3:2:1:2.
Preferably, step（1）In lime be magnesium lime, cement selection sulphate aluminium cement or ferrous aluminate cement.
Preferably, step（3）The temperature of middle molding kettle is controlled by using the waste heat of sintering oven.
Preferably, step（4）The natural curing refers to non-burning brick with after brick stacking machine stacking, stands in its natural state
15-20d, stacking height are 1-1.5m.
A kind of environment-friendly baking-free bricks that useless medical gypsum manufacture is recycled using orthopaedics provided by the invention, with prior art phase
Than haing the following advantages：
The type it is non-burning brick it is middle used discarded medical gypsum, and high-temperature roasting is carried out to gypsum before use, realize to stone
The harmless treatment of cream other than medical gypsum, further includes red mud and ceramic aggregate in material, red mud is sintering process or Bayer
The waste material that method aluminum oxide production process generates, ceramic aggregate are the substandard products wastes that ceramic sintering process generates, therefore of the invention
Technique realize a variety of solid wastes efficiently used, there is greatly environmental protection and the ecological value, and reduce production
Cost.
In the non-burning brick production technology of the type using the waste heat of the sintering oven of high-temperature roasting medical treatment gypsum come to it is non-burning brick into
Row dehydration and drying molding, technological process very energy conservation and environmental protection.
The fired brick of the present invention is made by unique formula and blanks and moulding and conserving technique productions, obtained non-burning brick performance
Excellent, compression strength is high, and wear-resisting property is good, is not easy to crush, and can be widely applied to the building wall of various non-load bearing walls.
