The specific embodiment
Stone flour with 1 li of building stones bucket, through metering device 2, take by weighing (5～80) order albarium (the white crystalline substance that bores) 4900Kgs, 800 kilograms of 100 order albariums, 1600 kilograms of micropowders (UF315 powder), drop to powder conveyer 3-1, be transported to 5 li in mixer by filler elevator 3-2, by agitator 5-1,1-2 does rightabout rotation, carries out siccative with the rotating speed of (7～9) r.p.m and stirs, and adds titanium dioxide 14Kgs and base colors of pigment 500g after about 1 minute, mix and stirred 5 minutes, control material water ratio≤0.05%;
With unsaturated polyester resin, even in advance saturated resin is 750Kgs altogether, inserts 4 li of resin buckets, adds promoter 0.6Kg, enters 5 li in mixer through tremie pipe 4-1, is guaranteeing under the trouble-free prerequisite of mixer, adds initator 9Kgs, mixes stir about 3 minutes;
Cover and the loam cake of the formula mixer 5 that is locked, start vacuum system, in the mixer vacuum reach-during 60cmHg, carry out the stirring of 3 programs by different rotating speeds, different time, unload vacuum, observe whether agglomerating or caking (size about 5～10cm) of material, as do not reach requirement, can add the about 10Kgs～20Kgs of an amount of saturated resin,, and unload vacuum until reaching agglomerating or caking.
In mill base paint can 6-2, mixed by 70% saturated resin and 30% titanium dioxide, make mill base, the feed pipe 6-3 that is connected with the plunger displacement pump 6 of spray gun 6-1 is inserted in the mill base paint can 6-2, start plunger displacement pump 6, at agitator 5-1,5-2 makes 2～3r.p.m and stirs down, and the spray while stirring is gone up the mill base that spraying has atomized toward material 5-0, per minute sprays 3～5Kgs approximately, stops after having sprayed the mill base about 10Kgs.Above-mentioned atomizing refractory gunning equipment can use 2 covers simultaneously, promptly uses plunger displacement pump 6 and plunger displacement pump 6 '.
With being sprayed with the material 5-0 of mill base, under vacuum-68cmHg, be discharged to 7 li on mould; Mixer 5 all places in the vacuum chamber I with mould 7.
Unload vacuum after unsnatching material, the mould 7 that material is housed is moved in the vacuum chamber II, starting vacuum system to indoor vacuum reaches-70cmHg, by air rammer jacking system 9-1,9-2 controls the lifting of pressure head 8, this jacking system is provided with many air rammer pumps, pressure head 8 whole youngsters place on the charge level of material 5-0, device has one group of 3 vibrator in the pressure head, tiltable to 18 °～21 ° is done the both forward and reverse directions rotation, thereby pressure head is produced vibration, jacking system is exerted pressure to pressure head and is reached 22MPa, exerts pressure while vibrating.Because the difference of the adjustable height of many piston pumps can be handled the inclination that pressure head is made certain angle, do the vibration of 4 different time programs and exert pressure by 8 couples of material 5-0 of pressure head.After unloading vacuum again, spontaneous curing can be carried out sawing to the square material in 7～10 days after the form removal about 10 hours.
