The specific embodiment
Like Fig. 1, shown in Figure 2, the production technology of marble composite board: (1) selection: at first select high-grade marble a kind, and to be processed into thickness through professional equipment be 15~30mm, the size stock board than the big 5~10mm of trimmed size.Next selects compound carrier blank 2 ceramic tiles, glass, aluminium matter cellular board, aluminium-plastic panel, and is processed into the stock board than the big 5~10mm of trimmed size through professional equipment.(2) oven dry: marble 1 is carried out thick surely, matting, move back net again and handle.Be thrown on the automatic conveyor line by suitable ratio; Dry up the back through hairbrush cleaning, flushing with clean water, blower fan and get into automatic rolling tunnel kiln oven dry; 40 ℃~90 ℃ of the temperature of rolling tunnel kiln, oven dry back through check, shovel net platform to check composite surface smooth, dust removal clean level, go net thoroughly whether, water evaporates gets thoroughly and waits.(3) compound: as to keep flat carrier material; Composite surface up; Simultaneously on its surface and the one side of marble hair plates coat the bonding agent for preparing, compound adhesive to be coated with uniform and thin, evenly on composite surface, all to be coated onto exactly and evenly can not leave hole, neutral gear etc.; Otherwise can influence timber intensity, and when grinding easy pressure break; Thin is exactly to be fit to bonding needs, just right, thick can cause waste and increase sheet metal thickness.One face down what scribble the compound adhesive hair plates to align and be combined on the carrier material that scribbles compound adhesive then; Then be coated with the thin and even compound adhesive of last layer at the another side of marble hair plates and the front of another piece surfaces of carrier materials more simultaneously; Scribbling compound adhesive carrier material simultaneously to another piece again is combined on the marble hair plates; Again its complex (splicing objects of a slice marble and two carrier materials) is removed to ready compound (specialty correction, the equipment of exerting pressure); Between every layer complex, to use rubber blanket and film to keep apart; Exert pressure in the above again, exert pressure and to suitable pressure, use firm mode administration of fixed, it is advanced solidify drying kiln intensification impelling curing subsequently; Through 4~8 hours fixed after, the curing glue to its release, cleaning outflow promptly becomes up and down for being the marmorean composite plate semi-finished product of one deck in the middle of the carrier material again.The thickness of composite layer 3 is thin as much as possible, is generally 0.1~0.2mm.(4) cut, to cuing open: will be up and down cut on the butt-splitting machine for the marmorean composite plate semi-finished product of one deck level of being contained in in the middle of the carrier material, be that two one sides are the compound hair plates of the marmorean marble of carrier material another side to cutting.The difference of these two marble hair plates 1 is under the normal condition: top plate thickness is thicker than following, decides according to the thickness of marble panel.(5) fixed thick, control is thick, corase grind, brush coating: because of the compound hair plates of marble is made up of marble, compound adhesive and carrier material 2 threes, thickness is variant unavoidably.Therefore, necessary control is thick.Moreover marmorean natural attribute: the surface hole, split line etc., so must be to its surface treatment, such as rubble, glue etc.Marble one with the compound hair plates of marble during work faces up, and reaches same thickness through the thick machine control of control is thick.Again through corase grind back oven dry, with the water evaporates of plate face fully after, employing rubble and glue etc. fill up marble surface the cavity, split line etc.The temperature curve of oven dry must arrive low from low to high again.Material according to marmorean lining is adjusted temperature curve, is generally: 40 ℃ 60 ℃ 80 ℃ 50 ℃ 40 ℃.Must guarantee the brush coating front face moisture processing thoroughly, fully, the glue that fill up hole, splits line can be selected for use according to marmorean difference and user's needs: unsaturated-resin or epoxy glue, and mix colours or do not mix colours processing.Quality brush coating work in order to ensure filling up processing must be adopted repeatedly, and frequent way must not leave the cavity of being untreated, split line etc. at the plate face, fills up composite plate behind the brush coating in order to carry out deep processing once more in the very first time.Shorten the production cycle; Difference according to the method for filling up; Also different to its processing mode: grind (6), polishing: will control thick, fill up the deep processings such as the compound hair plates employing carrying out of marble grinding and polishing after brush coating is handled after, become the compound tabula rasa of the very high marble of glossiness, inferior tabula rasa, plate modelled after an antique etc.Carry out must the composite plate hair plates being handled totally towards the glue nail of carrier material one side before the deep processing, in order to avoid the thickness that causes product because of just differing is different, panel is uneven.To keep product to advance the continuity of machine in the production process, must not be interrupted or folded brick, guarantee that product advances the uniformity of machine: like the name of an article, specification, thickness etc.(7) cutting, edging, chamfering: grind, the compound tabula rasa of marble after the polishing is cut to the composite plate of 300~1000mm specification through specialty, four limit chamfered have just become the marble composite board finished product again.Marble composite board finished product thickness after the processing is generally 11~15mm, and the marble thickness on the composite plate is merely 3~5mm.The marble composite board finished product changes QC department over to after through air-dry, oven dry, clean and carries out quality inspection.The temperature of finished product oven dry is as the criterion with oven dry plate face, is generally about 50 ℃, and the clean of plate face adopts the professional equipment wax-polishing machine of automatic lifting to handle.But the continuity that must guarantee product is for being good.(8) classification, color separation: the natural attribute of the panel of marble composite board finished product, physical imperfection etc. are inevitably, could pack so the product that processes must pass through the unified of grade distinguishing, colour system, are sold to the user and use.Flowing into automatic classification, color separation quality inspection line from automatic assembly line through processing the back completely; Earlier physical quality is distinguished clear, ranking score and will be delivered into automatic classification, color separation quality inspection line according to the difference of grade after choosing through quality inspection, and earlier according to pattern, the different automatic assembly lines of confirming that inflow is different of big colour system.Pack, beat and be with into holder by difference shallow, little colour system in dark according to colour table subsequently, warehouse-in keeping at last changes marketing company over to and sells.
