Abstract
A kind of is gypsum lightweight brick and the production technique thereof that filler is produced with flyash, adds flyash, strongthener, light skeletal mixing with semi-hydrated gypsum and adds water and stir, and is poured into mould or compression moulding, and demoulding drying obtains finished product.As the body of wall light filling brick of skeleton construction, in light weight, cost is low, and the fragment of brick physical strength meets national standard, is easy to produce use.
Description
The present invention relates to the material of construction preform.Especially non-lbearing wall material and production method thereof and application.
In the prior art,, press different components, different proportioning, make fragment of brick, building block etc. with materials such as gypsum, lime, portland cement, coal dust, chip ballast, cinder, slags.Wherein, based on the agglutinate of cement, lime, resistance to compression, folding strength are used for building foundation and carrying preform than higher more, and as the material of construction of non-bearing wall body, then the cost height need not sharply be promoted.
" a kind of new phospho-gypsum cementing agent and production method thereof and application " Chinese patent CN 1051719A " a kind of new phospho-gypsum cementing agent and production method thereof and application " is a kind of agglutinate based on gypsum and slag, utilize cheap gypsum and steel-making waste material one slag to produce brick and tile, building block as agglutinate, material cost is than using lime, cement considerably cheaper, but the necessary deironing of slag is levigate, make granularity less than 0.1mm, but increased cost and technology difficulty.Therefore, need cost lower in the actual production, the simpler new technology of technology.
The object of the invention provides the proportioning raw materials of a kind of non-bearing building materials-gypsum lightweight brick.Production technique and application mode.With flyash is main stuffing, and other auxiliary material utilizes simple production technique in addition.Reduce cost, produce product with certain physical strength.
The present invention adopts industrial residue-flyash that cheapness can get, gypsum (plaster of paris and/or phosphogypsum) as gelling material, add pearlstone or deposed polystyrene as light skeletal, add materials such as particulate calcium carbonate or cinder again, water is transferred and is mixed evenly, cast or compression moulding, air-dry or the oven dry, make gypsum lightweight solid brick, holllow building block and wallboard etc.
Its proportioning is:
Gypsum: flyash: strongthener: light skeletal
＝47-67∶11-35∶9-25∶1-4
Its technical process is as follows:
What need pay special attention to is that gelatinization material gypsum (plaster of paris, phosphogypsum) must pulverizing be milled down to 140 mesh screen residues less than 15%, is warmed to 120 ℃-210 ℃, and frying becomes semi-hydrated gypsum.To make strongthener lime carbonate, cinder be ground into particle in addition less than 15 millimeters.Also to be finely ground to particle to light skeletal pearlstone or deposed polystyrene less than 5 millimeters.With above-mentioned materials mixed on request, add water and stir at last, pour into mold, go into kiln drying after the demoulding or stack the air-dry finished product that obtains.
The light cinder brick of above-mentioned explained hereafter, intensity is more even, and discreteness is less, and fragment of brick physical dimension is regular, and ultimate compression strength 2.57～3.30MPa can satisfy the requirement (2.5～8.0Mpa) that walling is filled in non-bearing.This fragment of brick cost is lower, the weight ratio common brick light half, be easy to produce, not only can be made into solid brick, also can be made into building materials preforms such as hollow brick, holllow building block and wallboard.
Embodiment 1
Natural block gypsum is put into crusher, be broken into thin piece below 10 millimeters, put into grinding machine again and be milled down to 140 mesh screen residues less than 15%, send in the frying pan thereupon, heat to 120 ℃～210 ℃, it is standby to make semi-hydrated gypsum.
Flyash, the half water plaster of paris, light skeletal, strongthener are added water by table 1 stir, become leather hard, be pressed into fragment of brick with pressing machine then, behind the pile air-dry 15-28 days, promptly can be used as the light filling brick of skeleton construction.
Table 1
Embodiment 2
Waste-powdery the phosphogypsum (radioelement is no more than national standard) of phosphate fertilizer plant is heated 120 ℃～210 ℃ in drying kiln, make semi-hydrated gypsum, being milled down to 140 mesh sieves tails over less than 15% standby, prepare other raw material in table 2 ratio as embodiment 1, be cast in the raw material mixing and stirring in the stock mould rapidly, it is floating to be placed on the vibrator vibration, solidifies the back demoulding, natural air drying or send into the drying kiln inner drying and be finished product in 10-12 hour behind the pile.
Claims (6)
1, a kind of is the gypsum lightweight brick that filler is produced with flyash, it is characterized in that adding a certain proportion of flyash, granular calcium carbonate and light skeletal in the semi-hydrated gypsum, it cooperates part by weight is semi-hydrated gypsum: flyash: lime carbonate: light skeletal=47-67: 11-85: 9-25: 1-4.
2, light cinder brick according to claim 1 is characterized in that described gypsum can be the phosphogypsum or the plaster of paris.
3, light cinder brick according to claim 1 is characterized in that described lime carbonate, can be lime carbonate or cinder.
4, light cinder brick according to claim 1 is characterized in that described light skeletal, can be perlite or deposed polystyrene, haydite, float stone.
5, a kind of is the gypsum lightweight brick preparation method that filler is produced with flyash, it is characterized in that (plaster of paris, phosphogypsum are pulverized tailing over below 15% of 140 mesh sieves, are warmed to 120 ℃-210 ℃, and it is levigate again after semi-hydrated gypsum or the first frying that frying becomes with gypsum; Strongthener lime carbonate or cinder are broken into particle less than 15 millimeters; With flyash and any one light skeletal is that pearlstone or deposed polystyrene are broken into the particle less than 5 millimeters; By the aforementioned ratio mixing, poach pours into moulding box with above-mentioned materials, and is air-dry or go into kiln drying and be finished product after the demoulding.
6, a kind of is the gypsum lightweight brick purposes that filler is produced with flyash, it is characterized in that can be used as non-bearing material of construction such as solid brick, holllow building block and wallboard.
