Description

A method of lightweight wall plate is prepared using golden mine tailings
Technical field
The present invention relates to a kind of method for preparing lightweight wall plate using golden mine tailings, belong to industrial solid castoff utilize with Building energy conservation materials for wall field, and in particular to a kind of to utilize the industrial solids such as golden mine tailings, discarded dregs, flyash, sludge Waste, again by being machined into a kind of lightweight wall plate with heat preservation, fire-proof function after high temperature sintering.
Background technique
With the development of mining industry, the various mine tailings generated during mining activities, especially outstanding is golden mine tailings, Belong to solid waste, be deposited among mountains and rivers and river more, take up an area and pollute environment, some meetings generate great accident, give The people's lives and property causes heavy losses；
As urbanization, the speed-raising of urbanization, the reconstruction of the old city town in shanty town constantly expand, a large amount of castaway slag is produced Soil has biggish pollution to environment and underground water source；
The flyash of coal power plant discharge, also belongs to solid waste, also has pollution to environment and water source；
Sludge sand(-)washing plant will generate a large amount of washed-out sand sludge in the process of sand, the sewage of industrial enterprise is by heavy Form sediment the industrial sludge generated, the domestic sludge of city domestic sewage treatment plant settlement of sewage generation, harmful to environment, it is necessary to Carry out harmless treatment；
On the other hand, China uses most important thermal insulating material of the B2 grades of combustible material polyphenylene heat insulation slabs as building energy conservation Material, it is cheap although its thermal insulation property is superior, it is easy for construction；But it is easy to that serious fire occurs: as Beijing is entreated Depending on the wildfire occurred during the construction of exterior insulation system of new address 2009-02-03；The prosperous 2011-02-03 in Shenyang ten thousand is drawn due to fireworks The wildfire built up and occurred using the skyscraper outer heat preservation system of many years risen；Shanghai Jiangzhou road 2010-11-15 Building exterior wall heat preserving decoration renovation during the wildfire etc. that occurs, be all caused by polyphenylene heat insulation slab.For these Wildfire, relevant departments use series of improving measures, from heat preservation, fire proofing material to building heat preservation and architecture-integral. Although country pays much attention to the fire safety problem of architectural design, new to have formulated " Code for fire protection design of buildings " GB 50016-2014；But It is that by practice in recent years, or based on polyphenylene heat insulation slab, inorganic heat insulation material only accounts for few a part, few at this In the inorganic heat insulation material of part, the mainly foam glass of rock wool, air-entrained concrete building block, foam concrete block and fritter Deng, the lightweight wall plate of bulk cannot be formed, wall, but also substitution insulating layer have not only been substituted, and can be prevented fires, it is also durable.
How the solid waste such as golden mine tailings, discarded dregs, flyash, sludge are fabricated to one kind has heat preservation, prevents Fiery, durable lightweight wall plate, had both solved the problem of environmental pollution of above-mentioned solid waste, and it is energy-efficient also to solve energy saving building Heat preservation, heat-insulated, the integrated wall problem of fire prevention, are the projects urgently studied.
The present invention attempts to carry out existing energy saving building insulating wall material technology innovation, substitution, designs a kind of utilization Method of the solid waste such as the golden mine tailings preparation with heat preservation, the lightweight wall plate of fire-proof function, had both solved golden mine tailings, had given up The problem of environmental pollution of the industrial solid castoffs such as waste soil, flyash, sludge, also solve energy saving building heat preservation, every The deficient problem of heat, fire prevention integrated wall material, improves the thermal insulation property of wall, fire protecting performance, and endurance quality has accomplished to protect Adiabator and building same service life.

6) dry mash is in kiln successively by heating preheating, three Isothermal sinter, cooling down operation stages: preheating rank in heating Section, 9~25 DEG C/min of rate of heating, when temperature reaches 1130 DEG C, into the Isothermal sinter stage；The temperature in Isothermal sinter stage Degree range fluctuates between 1130 DEG C~1280 DEG C, Isothermal sinter time 0.5h~1.2h, the SiO of different trade wastes2、 Al2O3、CaO+MgO、K2The content of O+NaO is different, takes different Isothermal sinter temperature；In the cooling down stage, rate of temperature fall For 2~11 DEG C/min, belong to slow cooling, prevents sintering wallboard from generating stress cracking, until being cooled to 40 DEG C in kiln；
7) lightweight wall plate sintered is taken out out of mold；
8) lightweight wall plate is cut into defined size and shape by drawing；
9) cross to the baked light-weight wallboard (1) of well cutting, process an elongated boss (2), one it is elongated recessed Slot (3), several vertical through holes (4), several cross through hole (5) and vertical threading via hole (9), lateral threading via hole (10)；
10) vertical reinforcement (6) and fixation are placed in several vertical through holes (4), put transverse direction in several cross through hole (5) Reinforcing bar (7) and fixation；
11) metal connecting piece (11) for being located at cross through hole (5) both ends is weldingly connected with transverse steel (7)；
12) after placing vertical reinforcement (6) and transverse steel (7), into several vertical through holes (4) and several cross through hole (5) It is poured Self-leveling glues pouring machine (8)；
13) it will be poured the lightweight wall plate after Self-leveling glues pouring machine (8), and was sent into curing kilns and carries out steam curing or naturally feeding Shield；
14) lightweight wall plate conserved carries out presentation quality, dimensional discrepancy, mechanical property, thermal property, fire protecting performance etc. and carries out It examines；
15) to qualified product packaging；
16) product warehousing.
2. a kind of method for preparing lightweight wall plate using golden mine tailings according to claim 1, it is characterised in that: use this The lightweight wall plate of method production is by baked light-weight wallboard (1), boss (2), groove (3), several vertical through holes (4), several cross To through-hole (5), several vertical reinforcements (6), several transverse steels (7), glues pouring machine (8), vertical threading via hole (9), transverse direction Threading via hole (10), several metal connecting pieces (11) are constituted.
