Description
Technical field
The present invention relates to a kind of partition plate, more particularly to a kind of fungi-proofing partition plate.
Background technology
Oil shale waste is oil shale retorting or the remaining material of burning, loose structure, with good activity, thus purposes
Widely.Oil shale waste is silica-rich material, and the main component of oil shale waste is SiO2、Al2O3、Fe2O3, MgO, CaO etc., can use
Make construction material, such as high-grade cement filler, lightweight concrete aggregate haydite and lightweight brick.The comprehensive utilization of oil shale waste
Good resource, environment, economy and social benefit can be obtained, for realizing that the sustainable development of resource is significant.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of fungi-proofing partition plate of good physical performance.
Therefore, the raw material weight proportioning of soup processed for the thistle board that the present invention is provided is：33 parts~35 parts of oil shale waste, 10 parts of carbide slag
~12 parts, 8 parts~10 parts of cement, 15 parts~17 parts of hardwood pulp, nano oxidized 8 parts~10 parts of zinc solution, 20 parts~22 parts of water.
Oil shale waste fineness is that more than 50 mesh, cement uses effective calcium amount in 32.5 grades of Portland cements, carbide slag
More than 70%, carbide slag uses the waste residue that resin processing plant discharges.
Present invention also offers the manufacture method of above-mentioned ceiling board, comprise the following steps that：
(1) preparation of nano burnett's solution
Nano oxidized zinc solution makes in the following manner：Ammoniacal liquor is added drop-wise in zinc nitrate solution, makes solution system pH
Value is more than 9, then obtains precipitation with funnel, and sediment is washed with deionized repeatedly, until the pH value of system is close to 7；Keep
Temperature at 50 DEG C, gradually added into precipitation concentration be 0.95mol/L salpeter solutions stirring, to system pH to 3.5~4.1 it
Between, you can obtain nano oxidized zinc solution.
(2) hardwood pulp is handled
Bleached hardwood pulp can remove lignin contained in hardwood pulp completely in bleaching process, to bleach broad-leaved
Fiber is bonding with base material preferably after wood pulp steams for the product pressure of raw material, can improve the rigidity and bending strength of product.Bleaching
Crushed after hardwood pulp and sieve hardwood pulp particle, hardwood pulp grain diameter is 30~40 mesh.
(3) hardwood pulp particle is carried out antibacterial modified
Hardwood pulp is placed in closed pressure immersion can, plus nano burnett's solution, is pressurized to 1MPa, pressure is kept
1 minute, with a small amount of nano oxidized zinc solution of circulation pumped, make to produce vacuum in immersion can, continue after 1 minute by automatic tune
The direction that device changes four way valve is controlled, nano zine oxide is returned to again in immersion can by fluid filling pump, and make in immersion can
Pressure reach 1MPa.Changed the direction of four-way valve again after 1 minute, and by circulation pumped nano zine oxide solution, make
Immersion can formation vacuum.So it is repeated a number of times.Four-way valve is, by cam mechanism, to be adjusted with computer program controlled automatic, is realized
Vacuum, pressurization frequent transitions.Vacuum-pressurization is once a cycle, and process cycle reaches 60 times.
Nano zine oxide has extremely strong oxidation activity, can destroy the bioactivity and metabolism breeding function of bacterium, so that
Reach antibacterial purpose.In addition, nano zine oxide is under ultraviolet irradiation, the electronegative electricity moved freely can be voluntarily decomposited
Son, and the hole of positively charged is left, the oxygen activation in air is active oxygen by this hole, and active oxygen can be most of pathogens
With virus kill.Therefore, using nano granular of zinc oxide as antibacterial material, while being inhaled using the good ion of hardwood pulp fiber
Performance is received, the thistle board of strong antibacterial is obtained.By the ultrasonic wave of the hardwood pulp particle 35kHz after the processing of pressure immersion can
Handled, the processing time of ultrasonic wave is 4~5min, and temperature is 45 DEG C.
Nano zine oxide is introduced after hardwood pulp fibrocyte and gel, can effectively completely cut off hardwood pulp fiber and oxygen
The contact of gas, so as to suppress the progress of burning.Nano zine oxide is introduced in hardwood pulp fibrocyte, gel can effectively delay
The transmission of heat so that cell wall constituent can only be dehydrated carbonization, so that generation flammable volatility product during the thistle board pyrolysis of system
Speed substantially reduce, while the speed of heat transfer to lightweight plate surface slows down, flame retardant effect is obvious.
Ultrasonication can improve the Hydrogenbond between hardwood pulp fiber, so as to greatly improve the intensity of thistle board.
(4) slurry is made
Hardwood pulp particle after will be antibacterial modified is mixed with carbide slag, cement, oil shale waste and water, is stirred 5 minutes and is made
Into required slurry, pulp density is 11%~13%.Pulp density requires that slurry has good mobility but can not cross shunting
It is dynamic, while ensureing that slurry is uniform and stable, it is desirable to which slurry is extruded space not too much in pressure.
(5) stream slurry making sheet
The thickness of the thin bed of material should be controlled in 0.5~0.6mm during head box paving slurry dehydration forming；The rotating speed of agitator should be controlled
In 70~90rpm.
(6) it is dehydrated into base
Slurry is starched on felt through the uniform cloth of head box, is dehydrated through natural-dehydration and multi-stage vacuum, is formed uniform small powder, twine
It is around on forming tube, the shaping number of turns is 15~20, using Pneumatic Pressure, shaping air pressure is 0.25~0.3MPa, reaches that regulation is thick
After degree it is pneumatic go out knife pull base automatically, felt cleaning uses vacuum dehydration.
It is also more crucial factor from the preferable felt of permeability, the performance of felt directly determines the bed of material sometimes
Water separation capability.Felt selects acupuncture combination felt.
(7) pinch-off
The defective work of corner defect is more caused by mechanical trimming, and product appearance qualification rate is low, outward appearance defective work
It could also be sold by changing system into the sheet material of nonstandard specification, production cost remains high.In order to solve this puzzlement production
The problem of product presentation quality, uses high -pressure water cutting in pinch-off process.Base machine rubber conveyer belt will be connect and be changed to the thick nylon of 3mm
Base thin layer type belt of conveyer, to solve the sideslip of conveyer belt, will connect base belt feeder active upper roller and the positioning passive upper roller of belt and centre
Axis parallel degree between transition roller, three rollers is adjusted to be less than 1mm, and positioning belt cutting transporting velocity is 20m/min, connects base skin
Band cutting transporting velocity be 18m/min, make slab from connect base Belt Conveying to positioning belt it is longitudinally cutting during do not produce
Conveying cutting camber line, to ensure slab edge flatness, by the running orbit of vacuum piler transverse cuts shower nozzle with connecing base machine
Central axis degree is adjusted to be less than 1.5%, to ensure the edge-perpendicular degree of slab.Connect automatic by piler after base positioning Water Cutting
Stacking.
(8) high-temperature vapour is conserved
Piler is sent into still kettle and carries out steam press maintenance.Pressure is 0.9MPa~1MPa, is kept at this pressure
10h。
