Abstract
What the present invention provided is a kind of processing method that the magnesial gelatinized material of phosphoric acid is made various ornamental blocks that belongs to.It mainly is that the selection component proportioning is a magnesium oxide: magnesium chloride: hardcore: phosphoric acid salt=1000: 400: 1580: 8.5, stir to inject mould shake tiling then and establish the quartzite of small particle size, add again at last big particle diameter quartzite repeat to add in the processing method of particle diameter quartzite.The water-intake rate 2.2% of trimagnesium phosphate material, coefficient of softening 0.83, ultimate compression strength (MPa) 41, flexural strength (MPa) 12.8, it is very slight that weight loss-1.7% is returned the halogen phenomenon.Increase about 25% with amount of filler of the present invention, physicochemical data increases, and reduces cost about 20%.
Description
The invention belongs to the magnesial gelatinized material of phosphoric acid and make a kind of processing method of various ornamental blocks.
The ornamental blocks that prior art is made, its magnesium oxychloride material and their water-intake rate of trimagnesium phosphate material are respectively 9.5% and 3%, coefficient of softening is respectively 0.49 and 0.8, ultimate compression strength (MPa) is respectively 31 and 32, flexural strength (MPa) 12 and 12, weight loss is respectively-7% ,-2.2%, and it is respectively serious and slight returning the halogen phenomenon.
The ornamental blocks that the objective of the invention is to make will reduce its water-intake rate, improves coefficient of softening, increases resistance to compression, flexural strength, reduces weight loss and overcomes and return the halogen phenomenon.
Technical solution of the present invention:
The magnesial gelatinized material of phosphoric acid is made the processing method of ornamental blocks, it is characterized in that selecting proportioning components is magnesium oxide: magnesium chloride: hardcore: phosphoric acid salt=1000: 400: 1580: 8.5, above-mentioned composition stirred into inject mould behind the compound and shake is flat, the quartzite of small particle size paved on the compound in mould shake, treat that quartzite infiltrates the surface of compound bottommost mould, again big particle diameter quartzite filler is added, add medium particle diameter quartzite filler after the vibrations again, the vibrations direction is perpendicular, horizontal two-way staggered, the quartzite proportion of filler that adds is respectively that small particle size (2～4 centimetres) accounts for 30%, big particle diameter (8～15 centimetres) accounts for 40%, and medium particle diameter (4～7 centimetres) accounts for 30%.
Because what the present invention proposed is that a kind of processing method of taking realizes improving to greatest extent the quartzite amount of filler, gets final product corresponding minimizing chlorine, magnesian consumption, and can reduce the interior heat of this gelling material reaction preferably.
The ornamental blocks of the processing method manufacturing that this gelling material proposes with the present invention can solve the shrinkage strain and the lower shortcoming of water tolerance of this material better, improves its intensity and coefficient of softening, further reduces it and returns the halogen degree, reduces cost greatly simultaneously.
Embodiment:
Magnesia (containing MgO) 75%, 1000, magnesium chloride solution (Be28 °) 400, phosphoric acid salt, (sodium phosphate) 8.5, small particle size (2～4 centimetres) quartzite 474, big particle diameter (8～15 centimetres) quartzite 632, medium particle diameter (4～7 centimetres) quartzite 47, with the hard work powder, magnesium chloride solution, phosphoric acid salt mixes injection ornamental blocks moulding mold inside and promptly carries out transverse vibration, pave until compound and will expect again that in mold 4 spread and are layered on the compound, vertically vibrations are infiltrated the compound bottommosts until material 4, will expects that then 5 spread to be layered on and carry out on the compound that vertically horizontal two directions are staggered shakes, until greatly, the small particle size quartzite meshes fully.At last will in, big particle diameter quartzite adds and engagement with quadrat method.
Effect: the water absorption rate 2.2% of magnesium phosphate material, coefficient of softing 0.83, resistance to compression, bending strength are respectively 41,12.8(MPa), and the loss in weight-1.7%, it is very slight to return the halogen phenomenon. Reduce cost about 20%.
