Fig. 1 is the diagram isometric view embodying ceiling tile of the present invention; And
Fig. 2 is the schematic diagram using process of the present invention.
Detailed description of the invention
The present invention is applicable to the various building panels that can be used for covering wall or ceiling.A kind of suitable form of building panel is ceiling tile used in suspended ceiling or panel.Other forms of building panel comprise gypsum base walltile and wallboard.To be obtained by water slurry body or paste and the present invention is especially benefited from without the ceiling tile of impermeable layer or waterproof sheet material in the back side.Describing in the manufacture embodying ceiling tile of the present invention, with reference to Fig. 1 and 2 of accompanying drawing.Rectangle ceiling tile 10 is suitable as the inset type panel in the rectangular mesh in the suspended ceiling system of known construction.Ceramic tile has about 1/2 usually " to about 7/8 " between thickness and the nominal plane size of 2 ' x2 ', 2 ' x4 ' and 2-1/2 ' x5 ' or the metric equivalent of these panel size.Suspended ceiling panel or ceramic tile are obtained by water felt process or the water base preparation of casting of pasty state usually.When panel 10 is derived from water felt process, typical general preparation can comprise (by weight):
65% perlite filler
18% paper fiber
7% unmodified starch adesive, and
10% mineral wool fibres.
Mineral wool content can marked change, and such as until about 25%, and in this case, perlite can correspondingly reduce.Except paper fiber, other cellulose source can be used, as wood materials or woody plant material.When water felt product these compositions in water slurry body suitably mixed be incorporated in sieve is sprawled time, or when when casting ceramic tile, similar composition is sprawled in dish, these compositions are dehydrated and/or be dried to rigidity sheet material.Afterwards, the appearance side of sheet material or ceramic tile preform or front side surface coating or paint, described surface coating or paint are generally the water material with some latex or other binder components.When water felt pad or core, if needed, before with finish coat or top coat coating, can the facing side of grinding pad to produce flat surfaces.In addition, before using finish coat, priming paint can be applied to the face side of pad, described priming paint can be such as clay-based.The ceramic tile 10 of Fig. 1 installs orientation display with it, and the surface coating 11, priming paint 12, water felt pad or the core 13 that are included on its lower visible surface and the waterproof coating on its back side or upper surface 14 (discussing as follows).
As described in, the surface coating 11 on the facing side of ceramic tile 10 is generally water-based coating, and it has Chinese white color to provide high light reflectivity.Find, by by commercial waterproofing materials coated mat 13, this material can be used for successfully making ceramic tile 10 back side waterproof.Find unexpectedly, only need this material of relatively a small amount of to realize gratifying result.The example being applicable to implement product of the present invention is fluorocarbon polymer emulsion, as the large aurification European Company (DaikinChemicalEuropeGmbH by Dusseldorf ,Germany, Dusseldorf, Germany) with the fluorocarbon polymer emulsion of trade mark TG-5601 sale.This product is aqueous emulsion, and its available water is greatly diluted and remains valid simultaneously, even when rate of application inaccuracy.The result of diluting initial emulsion is extremely slightly being coated with of the anti-water solid of about 1/5 to 1/4 gram/ft.Although have the solid of such low concentration, find to achieve unexpected waterproof and water-fast degree.Under disclosed solid coverage scale, the water droplet beading in coating 14 also finally evaporates.
Fig. 2 shows the example implementing process of the present invention.The dry pad with solid content as above obtained by conventional water felt process or dry sheet material 13 deliver in spray booth 21 on conveyer 20, use water base top coat or paint 11 at spray booth 21 place.In this process, top coat or surface coating 11 are towards upper, but when ceramic tile is installed in ceiling, top coat faces down.Pad 13 is sent to dryer 22 by roller conveyors 23 from described spray booth.Sprinkler 24 with multiple spray nozzle extends on the whole width of conveyer between a pair cylinder of conveyer 23.The sprinkler 24 waterproof liquid 14 of above-mentioned dilution sprays the downside of pad 13.The pad 13 be coated with by top coat 11 and waterproofing materials 14 transports through dryer 22 by conveyer 26, and at dryer 22 place, these coating preferences are as drying simultaneously and/or the solidification duration of about 45 seconds at the temperature of about 220 DEG C.Can expect the additive method using top coat and waterproofing materials.Such as, roller coat or overflow can be used.
The water condensate that space above suspended ceiling or the pipeline in chamber and conduit drip can fall the back side of prior art ceiling tile, finally causes the variable color on face side or appearance side.Described variable color or the mechanism stained are attributable to condensed water and penetrate through ceramic tile.Condensate, can by the surface contamination of its process before arrival ceramic tile.In addition, when water permeation is by ceramic tile body, it may leach dyeing and produce material, as being present in the tannin in paper fiber or cellulose fibre.Contaminated water can leak through surface coating, stains surface coating thus.Due to wish ceiling tile be porous to demonstrate good sound absorption characteristics, therefore there is water source place, do not adopting in situation of the present invention, water through ceramic tile be common.Except porosity needed for typical ceiling tile, ceiling tile also has its initial water base characteristic, and described water base characteristic itself makes ceiling tile porous.
Be apparent that, the disclosure is the mode of citing, can not depart from the instruction that comprises in the disclosure to know under scope by increasing, amendment or remove details and carry out various change.Therefore, except being confined to degree that following claims must limit, the invention is not restricted to specific detail of the present disclosure.
