Description
Technical field
The present invention relates to a kind of dalle of construction material, relate in particular to a kind of manufacture method of glass fiber reinforced gypsum ice grating plate.
Background technology
At present, raising along with rapid development of economy and people's living standard, people have proposed aesthstic requirement to most building, for example: the inside fitting of buildings such as music hall, grand theater, assembly hall, require dalle appearance and modeling uniqueness, the surface is fine and closely woven, magnificent indeformable, also require simultaneously in light weight, intensity is high, fire prevention, environmental protection, requirement such as easy for installation, make its preferred material of such dalle is glass fiber reinforced gypsum.The inventor has proposed the application that name is called " Fiberglas reinforced plaster tablet and manufacture method thereof " on September 29th, 2007, and the Chinese invention patent communique discloses this part application on October 15th, 2008, and its notification number is CN101284722A.For improving the performance of plasterboard, critical material had glass chopped felt and fiberglass gridding cloth during it was formed in this method.These critical material roles are uselessly to doubt in sheet material, but for being similar to this structure of ice grating plate, glass chopped strand mats can't be laid, and it almost is helpless making for the member employing glass fiber reinforced gypsum of this fancy structure, can only abandon.
Summary of the invention
The objective of the invention is to provide a kind of manufacture method of glass fiber reinforced gypsum ice grating plate of production technology simplification at the prior art weak point.
The present invention is by the following technical programs in to realize: a kind of manufacture method of glass fiber reinforced gypsum ice grating plate, and its special character is to may further comprise the steps successively:
Step 1, join the slurry mix: calculate the required amount of member of making, press following proportioning: high strength gypsum powder 100, glass chopped silk and woven glass roving fabric: 〉=5, water reducer (0.2～0.5) %, set retarder (0.1～0.5) %, water 30～33 batchings, the taking-up woven glass roving fabric is stand-by, all the other are put into mixer and stir, and mixing time is 10-30 second;
Step 2, molded type: model is placed on the shaking table, in die cavity, be coated with one deck releasing agent, pour into a certain amount of slurry of preparing at the model cavity, make numerical control nozzle or the manual mould certain altitude place that is positioned at, along the spacing of mould institute by pre-set program given direction inweave woven glass roving fabric in turn, finish and pour into a certain amount of slurry of preparing of one deck after one deck inweaves, water and fashionablely make workbench vibration while pouring into, by this program repeat for several times, the height of numerical control nozzle of raising or hand after every end one secondary program;
Step 3, the demoulding, dehydration, drying: treat the demoulding after 30 minutes, take out finished product, send into hothouse, temperature is controlled at 60～80 ℃, and the time is 4 hours.
Described step 2 is the amount that goes out to need the glass fibre that adds according to goods slurry therewith calculation of total by this program repeat number of times for several times, considers that again products thickness draws amount that each need add and the number of times that applies.
Good effect of the present invention is: the manufacture method of the glass fiber reinforced gypsum ice grating plate that the present invention proposes, filled up a blank, the history that the ice grating plate that is through with can't be made of glass fiber reinforced gypsum.The glass fiber reinforced gypsum products appearance is fine and closely woven magnificent, and is indeformable, intensity is high, and advantage that can be seamless spliced again with closed perlite light weight, sound insulation, fireproof advantage, is the first-selected green building material of building decoration.The moulding of ice grating plate is because the planform complexity, screen wherein is very thin, method routinely can't make the gypsum slurry molded type that contains glass chopped higher silk of concentration, also can't use glass fiber sheets felt or glass grid cloth, adopts this method to realize the breakthrough of zero.Obvious improvement and tangible economic benefit have been obtained.
Description of drawings
Fig. 1 is construction process figure of the present invention.
Fig. 2 inweaves sequential schematic for non-twist group of yarn of embodiment of the invention flase floor glass fibre.
The specific embodiment
Below in conjunction with accompanying drawing concrete enforcement of the present invention is further described:
Fig. 1 has provided construction process figure of the present invention.Its step is as follows:
Step 1 is joined the slurry mix: calculate the required amount of member of making, press following proportioning: high strength gypsum powder 100, glass chopped silk and woven glass roving fabric 5, water reducer 0.3%, set retarder 0.3%, water 33.Numerical control nozzle feed bin is put in the woven glass roving fabric taking-up, and all the other batchings are put into mixer and are stirred, and mixing time is about 20 seconds;
Step 2, molded type: according to the amount of the glass fibre that adds, and products thickness draws amount that each need add and the number of times that inweaves.Goods are foursquare grid in the present embodiment, and its size is as follows: be 1500 * 1500 * 120mm, divide according to the calculating slurry to pour into for four times, also promptly divide three interpolation woven glass roving fabrics comparatively suitable.After finishing, preparation formally goes into the mould casting.
The mold type is placed on the shaking table, in die cavity, be coated with one deck releasing agent, pour into the slurry of being prepared by amount of calculation at the model cavity, its amount is 1/4 of total amount, water and fashionablely make workbench vibration while pouring into, make numerical control nozzle or manual mold height 1/4 place that is positioned at, along the spacing of mould institute by pre-set program given direction inweave woven glass roving fabric in turn, the order that inweaves woven glass roving fabric for foursquare grid is from first to last to unroll from the direction of latitude earlier, as shown in Figure 2, unroll around to afterbody, turning to, be returned to around finishing to inweave for the first time from the direction of warp; Pour into for the second time the slurry of being prepared, its amount is 1/4 of total amount, continue to make the workbench vibration not stop, again with numerical control nozzle or manual mold height 1/2 place that places, along mould earlier along warp-wise, inweave woven glass roving fabric one deck in turn along broadwise then, pour into 1/4 of the 3rd layer of slurry total amount of being prepared after having inweaved again, pour into when finishing again with the numerical control nozzle or manual place mold height 3/4 place along the first broadwise of mould, warp-wise inweaves woven glass roving fabric one deck in turn then, pours into the slurry that last one deck is prepared again.
Step 3, the demoulding, dehydration, drying: treat the demoulding after 30 minutes, take out finished product and be placed on to be drained off doing on the dolly that send on the motorized conveyor belts of hothouse, temperature is controlled at 80 ℃, the time is 4 hours, goes out the clear face of shaping behind the chamber.
Glass fiber reinforced gypsum ice grating plate according to above-mentioned prescription and preparation method are made carries out the test of mechanical performance, and its result is as follows:
| Sequence number | Project | Unit | Actual measurement |
| 1 | Bending strength | Mpa | 24.1 |
| 2 | Compression strength | Mpa | 16.9 |
| 3 | Fire resistance | h | 1.2 |
Above-mentioned example is not construed as limiting the invention, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within protection scope of the present invention.
