Abstract
The invention relates to a novel magnesite well lid, which comprises the following ingredients in percentage by mass: 25 to 35 percent of light burning powder, 15 to 25 percent of magnesium chloride, 20 to 30 percent of water, 0.4 to 0.5 percent of modifying agents, 25 to 35 percent of inorganic fillers, 5 to 10 percent of organic fillers, 0.3 to 0.5 percent of water-based pigment, 2 to 4 layers of medium-alkali glass fiber cloth and 4 to 8 layers of bamboo grids. A manufacture process of the novel magnesite well lid comprises the following steps that firstly, the light burning powder, the magnesium chloride, the water, the modifying agents, the inorganic fillers, the organic fillers and the water-based pigment are sequentially added for preparing magnesite slurry; and then, the magnesite slurry is poured into a cleaned mold, the medium-alkali glass fiber cloth and the bamboo grids are added layer by layer, the mold is placed on a vibration table, the vibration formation is carried out, the reaction, the curing and the demolding are carried out, the maintenance is carried out during the age, and the novel magnesite well lid is obtained. The novel magnesite well lid has the characteristics that the weight is light, the intensity is high, the appearance is attractive and elegant, the anti-theft effect is realized, the cost performance is high, the manufacture process is simple, and the like. The novel magnesite well lid can be widely applied to places including residential quarters, green belts, parks and other places without passing of large-scale vehicle.
Description
Technical field
The present invention relates to a kind of novel magnesia cover of manhole.
Background technology
At present, at home, in the outer urban construction, various pipe-line systems such as draining, coal gas, oil transportation, fire-fighting are arranged all.The material of the well lid of these pipe-line systems is metal mostly.That the well lid that this material is made has is not attractive in appearance, perishable, in shortcomings such as the effect of impacting external force are easy cracked down, price is high, be prone to lose.
Summary of the invention
The objective of the invention is to overcome above shortcoming; For people provide a kind of high-strength light, elegant in appearance, anti-theft antitheft, high, the simple novel magnesia cover of manhole of manufacture craft of cost performance, can be widely used in the place that residential quarter, greenbelt, park etc. do not have oversize vehicle to pass through.
For realizing above-mentioned purpose, the technical scheme that the present invention takes is following:
A kind of novel magnesia cover of manhole is a cementitious matter by modified magnesite cement, adds a large amount of inorganic organic fillers and small amounts of pigment and processes.The mass fraction of its each component is: light burnt powder 25～35%, magnesium chloride 15～25%, water 20～30%; Modifier 0.4～0.5%, inorganic filler 25～35%, organic filler 5～10%; Aqueous pigment 0.3～0.5%, 2～4 layers of medium alkali fiber cloths, 4～8 layers of bamboo grids.Its manufacture craft is: earlier light burnt powder, magnesium chloride, water, modifier, inorganic filler, organic filler, aqueous pigment are prepared the magnesite slip in order; Then the magnesite slip is poured in the good mould of cleaning, successively added medium alkali fiber cloth and bamboo grid, mould is placed on the vibroplatform, vibration moulding, the maintenance of question response cure and demold got final product to the length of time.
Novel magnesia cover of manhole of the present invention uses modified magnesite cement to be cementitious matter, and product weight is light, intensity is high, long service life, and the organic-inorganic inserts of admixture is mainly industrial and agricultural wastes such as sawdust, agricultural crop straw, flyash, slag ash, stone flour; Price is low, turn waste into wealth, simultaneously in water mixing property pigment, make product color evenly attractive in appearance; Nontoxic, energy-conserving and environment-protective; And the product recovery value is low, and the anti-theft antitheft is a kind of well lid of high performance-price ratio.
The specific embodiment
Embodiment 1
A kind of novel magnesia cover of manhole, its manufacture craft is: earlier 30 parts of light burnt powders, 19 parts of magnesium chlorides, 20 parts of water, 0.4 part of modifier, 25 parts of inorganic fillers, 5.3 parts of organic fillers, 0.3 part of aqueous pigment are prepared the magnesite slip in order; Then the magnesite slip is poured in the good mould of cleaning, successively added 2 layers of medium alkali fiber cloth and 5 layers of bamboo grid, mould is placed on the vibroplatform, vibration moulding, the maintenance of question response cure and demold got final product to the length of time.
Embodiment 2
A kind of novel magnesia cover of manhole, its manufacture craft is: earlier 25 parts of light burnt powders, 20 parts of magnesium chlorides, 18 parts of water, 0.5 part of modifier, 30 parts of inorganic fillers, 6.1 parts of organic fillers, 0.4 part of aqueous pigment are prepared the magnesite slip in order; Then the magnesite slip is poured in the good mould of cleaning, successively added 3 layers of medium alkali fiber cloth and 7 layers of bamboo grid, mould is placed on the vibroplatform, vibration moulding, the maintenance of question response cure and demold got final product to the length of time.
Claims (3)
1. a novel magnesia cover of manhole is a cementitious matter by modified magnesite cement, adds a large amount of inorganic organic fillers and small amounts of pigment and processes; It is characterized in that: the mass fraction of each component is a light burnt powder 25～35%, magnesium chloride 15～25%, water 20～30%; Modifier 0.4～0.5%, inorganic filler 25～35%, organic filler 5～10%; Aqueous pigment 0.3～0.5%, 2～4 layers of medium alkali fiber cloths, 4～8 layers of bamboo grids.
2. magnesia cover of manhole according to claim 1 is characterized in that: bamboo grid is to be woven by the bamboo reinforcement that fresh bamboo bamboo meat is partly processed to form, and should dry subsequent use after 24 hours with the bittern immersion in advance during use.
