The every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.It needs
Illustrate, in the absence of conflict, the features in the embodiments and the embodiments of the present application mutually can be combined arbitrarily.
Flyash is the solid waste that coal-fired fluidized bed furnace passes through electric exclusion of gathering dust, and discarded flyash will not only occupy
A large amount of soils dance in the air pollution air all over the sky to the wind, and rainy day enters underground pollution underground water, constitute to ecological and environment dual
It destroys.Meanwhile flyash is a kind of regenerated resources that can be developed and utilized, fully research is applied in gypsum board manufacture not only
It can solve the problems, such as flyash land occupation, pollution environment, but also vast resources can be saved and be directed to above-mentioned problem and country
Energy-saving and emission-reduction are badly in need of.Present invention combination power plant desulfurization gypsum material characteristic, the requirement of Paper-faced gyp plate technique, innovation research go out gypsum
The efficient forming method of plate and formula, production overall process center automatic control system.It as admixture and is taken off using industrial flyash
The frying of sulphur gypsum, grinding, produce lightweight Thistle board, reduce production board brittleness, density and production cost, reduce crackle and improve
The effect of final product quality.
Fig. 1 is the flow chart of the production method of the plasterboard using Resource recovery in the present invention.The producer of this plasterboard
Method includes：
Step 1：Step 101：Gesso, flyash, glass fibre, modified starch are set by respective metering conveying
Blender is inputted for entering after mixing reamer is sufficiently mixed；Step 102：By foaming agent by foaming agent measuring equipment, water is led to
Water measuring equipment is crossed, enters blender after being mixed by preset ratio；Step 103：Water is added in blender；
Step 2, blender, which is stirred, is infused in slurry between upper layer mask paper and lower layer's mask paper；It is squeezed through former
Pressure obtains plasterboard wet plate；
Step 3, plasterboard wet plate is transported by forming belt, after the solidification of plasterboard wet plate, is cut off, dried, sawed
Gypsum board product is made in side.
This three sub-steps of step 101, step 102, step 103 can be carried out at the same time in step 1, can also be by preset
Sequencing execute, step 101, step 102, step 103 preset sequencing share 6 kinds.
The composition proportion of plasterboard in this method using Resource recovery is as follows：The weight of gypsum board product is 100 parts,
The proportioning mode of the mass parts of raw material is：
The quality of gesso is 95~98 parts；
The quality of flyash is 2~5 parts；
The quality of water is 75~78 parts；
The quality of foaming agent is 0.1~0.15 part；
The weight of modified starch is 0.4~0.5 part；
The quality of glass fibre is 0.1~0.12 part.
Foaming agent accounts for the 2~3% of the mixed liquor of foaming agent and water in step 102.
Water accounts for the 75~78% of the summation of the water in step 103 and step 102 in step 103.
Further include the method for obtaining gesso before step 1, this method for obtaining gesso includes：By desulfurated plaster
It is smashed by beater, gypsum particle is collected by electronics dust-precipitator, gypsum particle is ground by grinder and obtains the plaster of paris
Powder.
Further include the method for obtaining flyash before step 1, this method for obtaining flyash includes：In coal combustion furnace
Fly ash grain is collected using electronics dust-precipitator at heat exchanger, fly ash grain is ground by grinder and obtains flyash.
In this method, the flyash of 95~98% gesso and 2~5% is subjected to mixed grinding modification.The plaster of paris
Powder meets water hydratable hardening, forms gypsum volume mesh structure and generates intensity, 30% intensity is provided for Thistle board, flyash is
A kind of loose solid aggregation, the oxide containing elements such as silicon, iron, calcium, magnesium and some trace element, rare elements
The fine grained of composition, because containing heterogeneity in flyash, flyash is less than 5~8% when mixing different substances together different proportion and is used for plasterboard
Production process can play fire prevention, heat-insulating property, have suction-operated, and panel strength is without being substantially reduced.The incorporation 2 of flyash~
5% replaces desulfurated plaster, improves forming station phosphoric acid, improves the workability of slurry.
Foaming agent can make to be uniformly distributed stomata in plate core, reduce plasterboard mass area ratio.
Modified starch can usually use modified starch as the binder of plate core and mask paper using in Thistle board.In paper
Modified starch used in gypsum board manufacture is generally sour modified corn starch.Starch is in gypsum board manufacturing process with water vapour
It migrates to plate core and shield face paper interface, plays cementation.Therefore the molecular weight of modified starch, gelatinization point, viscosity all can
Influence its adhesive property.
Glass fibre has fire resisting and improves the strength and toughness of plate core.
Fig. 2 is using the structure chart of the production system of the plasterboard of Resource recovery, this system includes：
Gesso metering conveyor, flyash metering conveyor, glass fibre metering conveyor, modified starch
Metering conveyor, with the output end of gesso metering conveyor, the output end of flyash metering conveyor, glass fibers
