The preparation method of a kind of gypsum base gravity flowing levelling mortar or dry-mixed mortar, it is characterized in that: fuel-burning power plant institute exhaust gas discharged is carried out high-purity dihydrate gypsum that gained is handled in desulfurization with aqua calcis, at 150 ± 50 ℃ of semi-hydrated gypsums that carry out making behind the calcined dehydration, or carry out making dehydrated gyp-behind the calcined dehydration at 600 ± 50 ℃; With semi-hydrated gypsum or dehydrated gyp-as main gelling material, add various aggregates and various chemical additive efficiently according to the above ratio in factory-configured, mix and a kind of dry-mix that is specifically designed to floor leveling of making: gypsum base gravity flowing levelling mortar or dry-mixed mortar.
This mortar has good flowing property, and the energy Automatic Levelling can be used for interior architecture thing floor leveling, as is used to fill the uneven of ground, micro-cavity and crack etc.The levelling that can be widely used in ground such as indoor laying carpet, PVC floor, timber floor is handled, and is specially adapted to floor heating system (hot-water heating or electricity are warm).
More than in other raw material except flyash, slag be when each power station is bought by levigate excessively, other raw material is all from various markets, especially buy on the building materials market, for example: Wingdale is the Wingdale of the levigate mistake bought from the building materials market, remaining again other raw material is bought from various markets, is not just enumerating one by one herein.
The pore structure that an important feature of the present invention is the gypsum base mortar is crystallizated into the needle-like crystal intersection by dihydrate gypsum and forms, so in needle-shaped crystal structure, exist a large amount of freeboards, be that voidage is very high, so when humidity is too high in the air, the gypsum base mortar can absorb airborne moisture content by the pore structure, that is to say: in its internal pore structure of gypsum base mortar, can store a large amount of moisture content, and when outside atmosphere is dry gradually, the moisture content of these storages can be evaporated in the room air gradually along the pore structure and go, thereby further reduce atmospheric moisture, come atmospheric moisture in the surge chamber with this, that is to say: gypsum-based construction material has certain " breathing " function, well the atmospheric moisture in the surge chamber;
Another important feature of the present invention is that the gypsum base mortar has good performance in fire, and this mainly is because dihydrate gypsum (CuSO
4.2H
2O) chemically contain two crystal water, just contain about 21% crystal water (so-called " fire extinguishing water "), when high temperature, crystal water in the energy discharging structure, (its reaction formula is face as follows), these moisture content can be diffused in the air of surface of wall rapidly, and then at materials for wall surface formation one deck " aqueous vapor film ", should " aqueous vapor film " can reduce the temperature on materials for wall surface, and can play the effect of isolating oxygen again, stop and delayed the further burning of materials for wall/buildings with this.
About 21% (weight)
Compared with prior art, the invention has the beneficial effects as follows:
1, compares with the concrete base building material, the voidage of gypsum mortar is very high, when humidity is too high in the air, can absorbs airborne moisture content, and store a large amount of moisture content, when outside atmosphere is dry gradually, the moisture content of these storages can be evaporated in the room air gradually and go, and reduces atmospheric moisture, the atmospheric moisture in the surge chamber, that is to say, well the atmospheric moisture in the surge chamber;
2, the gypsum base mortar has good performance in fire, when high temperature, crystal water in the energy discharging structure, moisture content can be diffused in the air of surface of wall rapidly, form one deck " aqueous vapor film " on the materials for wall surface, both can reduce the temperature on materials for wall surface, and can play the effect of isolating oxygen again, stop and delayed the further burning of materials for wall/buildings with this;
3, can guarantee the quality of sand-cement slurry: this is because the performance of gypsum base mortar itself: the common quality defect of sand-cement slurry such as for example its surface compressed crack, hollowing can not occur, come off;
4, nontoxic, tasteless, harmless to skin, workability is good, and easy construction is fit to the mechanical execution fast drying, the intensity height, and wear resistance is good, can disposablely carry out the metope levelling;
5, good heat insulation and preservation effect is arranged, fire line is good, has certain " breathing " function, well the atmospheric moisture in the surge chamber;
6, adaptability is strong: be easy to bond wallpaper and ceramic tile, can make the kinds of surface decorating structure.
Narrate the performance of gypsum base gravity flowing levelling mortar below again:
Gypsum base gravity flowing levelling mortar good fluidity, and internal stress is low, is difficult for forming the crack;
(concrete thickness is relevant with the prescription of gypsum base gravity flowing levelling mortar but one-off construction is from 1mm-60mm! );
Can be used for thin layer floor heating system (electrically heated and water heating system);
But about 30min of engineering time;
Available mechanical means is carried out auxiliary construction, can further improve operating efficiency and construction quality;
Gypsum base gravity flowing levelling mortar rate of set is fast, can go up about 4～24h between man-hour;
The about 15-30N/mm of mortar ultimate compression strength (28 days);
The about 5-10N/mm of mortar folding strength (28 days);
The about 1.6kg/m of mortar consumption
2Mm (concrete consumption is relevant with the surface pore structure/crude degree of substrate and the denseness of mortar etc.);
The gypsum base gravity flowing levelling mortar meets German hazardous material regulations of rules (GefStoff V), does not contain hazardous material;
Fire-protection rating A1 (with reference to 96/603/EG).
All under laboratory condition, room temperature is 20 ℃ to above data, and 65% relative air humidity records.
