Detailed description of the invention
Be below specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiments.
Embodiment 1
As depicted in figs. 1 and 2, the making mould of this inorganic compounding door sleeve comprises the patrix for making door sleeve plate 4 and the counterdie for making cutting 3, counterdie comprises housing 7 and is arranged on two adjusting rods 8 of housing 7 inside, two adjusting rods 8 be arranged in parallel and two ends are all touched mutually with the medial surface of housing 7, and the top and the bottom of adjusting rod 8 and housing 7 enclose above-mentioned die cavity 1.Be provided with a demarcation strip 2 in the die cavity 1 of counterdie, this demarcation strip 2 by under touch die cavity 1 and be separated into the die cavity 11 that two are used for pouring into a mould cutting 3.
The preparation method adopting above-mentioned mould to carry out the making of inorganic compounding door sleeve comprises the steps:
Step 1, prepare the magnesium chloride brine of 25 Baume degrees;
Step 2, prepare chloro-magnesium cement slurry: by magnesia and magnesium chloride brine Homogeneous phase mixing, the ratio of weight and number of magnesia and magnesium chloride brine is 1: 1;
The preparation of step 3, modifier: modifier is made up of (parts by weight) following composition and proportioning: barium silicate 3, sodium metasilicate 2, macromolecule waterproof adhesive powder 16, plaster of Paris 310, bentonite 130, mica powder 75, lithium metasilicate 3, polyvinyl alcohol 5, flocculant 6, talcum powder 200, volcanic ash 250;
Step 4, preparation cutting 3 mixed slurry: in chloro-magnesium cement slurry, add modifier, the alkali-free glass fibre of the short 5mm of cutting is stirred to Homogeneous phase mixing, the addition of modifier and short chopping alkali-free glass fibre is 10%, 3% of magnesium chloride brine weight in step 2 respectively;
Step 5, prepare door sleeve plate 4 mixed slurry: in chloro-magnesium cement slurry, add modifier be stirred to Homogeneous phase mixing, the addition of modifier is 5% of magnesium chloride brine weight in step 2;
Step 6, making cutting 3: as shown in Figure 4, in the die cavity 11 of counterdie, pour into cutting 3 mixed slurry obtained by step 4;
Step 7, making door sleeve plate 4: tile one deck alkali-free glass fibre grid cloth bottom patrix, then adopt painting way on this layer of alkali-free glass fibre grid cloth, brush door sleeve plate 4 mixed slurry of preparation in one deck step 5, then brushing one deck door sleeve plate 4 mixed slurry is again re-layed after one deck alkali-free glass fibre grid cloth, so repeat certain number of times, the number of times of repetition determines the thickness of door sleeve plate;
Step 8, matched moulds; By patrix left-hand thread on counterdie, cutting 3 uncured in door sleeve plate 4 uncured in patrix and counterdie is bonded together;
The demoulding after step 9, curing conservation.
Owing to the addition of improver, after magnesia cement solidification, form one deck hydrophobic membrane at the inner surface of goods with inner capillary porosity and empty inwall, prevent the intrusion of moisture, reduce water to the erosion of goods.Magnesite modification agent simultaneously contains the surface active ingredient of a great deal of, can magnesia be made at short notice fully to contact with magnesium chloride, react, unnecessary magnesium chloride shielding is got up, it is made to lose the chance absorbing moisture in air dielectric, compensate under large output, slip mixing time is shorter and the defect easily causing mixing of materials insufficient.Eliminate in urethane cure process, the product defect produced because of excess water evaporation significantly increases the early stage of goods and long-term strength, increase surface and inner packing, halogen and whiting are returned in elimination, strengthen the hydrophobicity of product, and the activity be combined with CO2, reduce and generate shepardite, increase magnesium carbonate to generate, improve stability and intensity.
In the present embodiment, two die cavities 11 have been separated out by demarcation strip 2 in counterdie, therefore two root cuttings 3 can once be formed, door sleeve plate 4 moves in counterdie die cavity 1 and carries out bond (as shown in Figure 4) with two root cuttings 3 simultaneously, also to cut along dotted line in figure door sleeve plate 4 after cure and demold, form two independently door sleeves.According to above-mentioned thinking, control the counter motion of two adjusting rods 8, expand the length of die cavity 1, just several pieces of demarcation strips 2 can be set multi-compartment, expand the quantity of die cavity 11, to reach the object of the multiple door sleeve of disposable making.
As shown in Figure 4, the thickness of demarcation strip 2 is less than the thickness of counterdie die cavity 1, and demarcation strip 2 is provided with and regulates blend stop 6, regulates blend stop 6 vertical with die cavity 11 and flushes with adjusting rod 8 and housing 7, regulate the two ends of blend stop 6 to be equipped with cut-off block 5, cut-off block 5 just lays respectively in two die cavities 11.When the door sleeve length that will make changes, can drive and regulate blend stop 6 and cut-off block 5 to move along die cavity 11, change the effective length of die cavity 1 with this, regulate blend stop 6 also to can be used as the effective rib enclosing die cavity 1 simultaneously, carry out spacing to door sleeve plate 4.
Structure and the counterdie of patrix are similar, and difference is do not have demarcation strip 2, and the head trim line plate 4 therefore made is tabular.
