Abstract
The utility model relates to a light partition board made of flue gas desulfurization gypsum. The light partition board made of flue gas desulfurization gypsum comprises a main wall which is provided with vertical through holes divided into three rows by ribs. The light partition board made of flue gas desulfurization gypsum provided by the utility model has the beneficial effects that the light partition board made of flue gas desulfurization gypsum is light in weight, high in strength, good in soundproof performance, anti-impact and small in retraction, and the insulating, soundproof and heat insulating functions of buildings are improved, so that raw material consumption is reduced, and the cost is lowered. The light partition board is suitable for being used as an inner wall blocking material for buildings.
Description
Technical field
The utility model relates to a kind of partition board, especially a kind of flue gas desulfurization gypsum light cellular partition board.
Background technology
80% of China's construction material is still loam brick, and wherein major part is clay solid brick, is unfavorable for protecting the soil, energy conservation.Novel wall material give priority to have alleviate that body of wall deadweight, energy conservation and soil, raising efficiency of construction, the building board that improves building function, building block and non-clay turn, various hollow brick, combined wall etc.The Overseas New materials for wall mainly contains 3 large classes: hollow brick, concrete hollow block and building board.The present building board output of China is 1.46 hundred million m approximately
2, about 0.88 hundred million m of gypsum plank wherein
2, light cellular partition board 0.58 hundred million m
2Although building board in novel wall material proportion near 5%, proportion 1% left and right only in whole materials for wall.Gypsum plank has been subject to suitable attention in the development of China, brought into play effect for promoting wall reform, but, light cellular partition board as the internal partition wall substitute does not but obtain general application, except be subjected to economics dictate and understanding not deep enough, also there are certain quality problems in light cellular partition board self: sheet material crack (comprise assembly unit crack) and sound-proofing are poor.The flue gas desulfurization gypsum light cellular partition board of Development of Novel should reduce drying shrinkage value, and emphasis solves the sheet material crack problem; Changing single row of holes is many rounds or filling core, improves the sheet material sound insulation value, satisfies a minute family partition wall requirement.Along with comfortable house and live in peace dwelling house to the modernization future development, large bay system ratio increases gradually, estimates that the demand of light cellular partition board is increasing, will have better growth momentum.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides that a kind of quality is light, intensity is high, sound insulation value is good, shock resistance, the little flue gas desulfurization gypsum light cellular partition board of contraction.
The utility model solves the technical scheme that its technical problem adopts: this flue gas desulfurization gypsum light cellular partition board, comprise main wall, and main wall is provided with vertical through holes, and these vertical through holes are separated into 3 rows by rib.
As preferably, be staggered the layout between row's vertical through holes.
As preferably, the partition board outer wall thickness is not less than 12mm, and inwall is 10mm.
As preferably, among described 3 row's vertical through holes, a middle row is circular hole, and front and back two rows are oval flat hole.
As preferably, the bond length in described ellipse flat hole is not more than 10mm.
As preferably, partition board both sides are respectively equipped with groove and tenon.
The effect that utility model is useful is: the utility model quality is light, intensity is high, sound insulation value is good, shock resistance, the little light cellular partition board of contraction, can improve the insulation, sound insulation of building, the function such as heat insulation, reduce raw materials consumption, reduce costs, the inner wall that is suitable as building cuts off material.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Description of reference numerals: main wall 1, rib 2, groove 3, tenon 4, vertical through holes 5.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: as Fig. 1, this flue gas desulfurization gypsum light cellular partition board comprises main wall 1, and main wall 1 is provided with vertical through holes 5, and these vertical through holes 5 are separated into 3 rows by rib 2.Be staggered the layout between row's vertical through holes 5, to increase the hot-fluid route.Among 3 row's vertical through holes 5, a middle row is circular hole, and front and back two rows are oval flat hole, by reducing hole diameter and increasing hole ratio, can effectively reduce the convection heat transfer intensity of air layer, improve the thermal and insulating performance of partition board.
By heat transfer theory, hole wall is healed better thin, and the partition board outer wall thickness should not be less than 12mm, and inwall is 10mm.Wherein oval flat hole bond length is not more than 10mm, can reduce convection current and the radiant heat transfer of air, in the situation that bond length is certain, can increase the elongated edge size as far as possible.
The partition board both sides are respectively equipped with groove 3 and tenon 4, effectively solve the cold bridge problem that integral rigidity reaches body of wall not.
This partition board is take industrial residues such as flyash, flue gas desulfurization gypsum, Superlight ceramsites as main raw material(s), adopts mechanical agitation, formwork erection to become the process meanses such as composing type or the moulding of flat-die unit flowing water, setting accelerator rapid curing, oven dry maintenance to form.Concrete manufacturing process is as follows:
(1) measuring raw materials: the industrial residues such as flyash, flue gas desulfurization gypsum, Superlight ceramsites according to predetermined match ratio, are measured respectively;
(2) stirring pulping: the industrial residues such as flyash, flue gas desulfurization gypsum, Superlight ceramsites of metering are mixed, stir and make slip;
(3) mechanization making sheet: mechanical agitation, formwork erection become composing type or the moulding of flat-die unit flowing water, setting accelerator rapid curing, make the partition wall sheet material of designing requirement thickness;
(4) oven dry maintenance: with partition wall sheet material curing in the mold, treat the slip curing and demolding, stack, carry out secondary moisturizing natural curing, until plate property reaches designing requirement;
Have following feature:
Surface density :≤60kg/m
2Drying shrinkage value :≤0.4mm/m; Bending resistance rupture load: be not less than 1.0 times that plate is conducted oneself with dignity; Shock resistance: 30Kg sandbag drop 0.5m swings and impacts 5 times, through check do not occur; Weighted sound transmission loss: 〉=40dB.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
