Description

Water resistant ceiling tile for Full Description Background of the invention The disclosure relates to improvements in prefabricated building partitions and; particulary; With roof tiles made of water slurry or water based paste. for prefabricated building blocks; Specifically; Waterproof roof tiles tend to become stained when exposed to water. One of the mechanisms by which water droplets come into contact with the ceiling tile is condensation on pipes and ducts in the space above the roof. The condensate can drip onto the backside of the roof slab and migrate to the appearance improvement side al of the slab. Staining can occur because water can transfer contaminants from the surfaces it touches and often because water droplets travel through the ceiling tile and leaching scum from recycled newsprint or other plant-based cellulose materials And staining agents are other ingredients used in Turkish tiles, which make these staining agents, Jie, on the front surface of the tile. It is also typical for most products; Cost is critical and an economical solution is needed to reduce water spots on the appearance improvement aspects of cell slabs and in particular; Water pervious ceiling tiles Vo YYvy

Y —_ _ and JS from US Document No. 1414585 0018/ and JN+4757 70 disclose a roof tile construction using a waterproof foil and a foil-filled flask; respectively on the backside of the tile. General description of the invention ° The invention provides an economical solution to the issue of water spots on the visible face of the building tiles due to the migration of water through the tile. More specifically, the invention asserts that by Jala forming water droplets at the backside of the tile, the droplets can be evaporated before their liquid content penetrates through the tile 016. It has been discovered that a commercially available material used to impart water solvency to a cloth is an excellent ye medium for carrying out the object of the invention. Jie considers this material available as candy and non-toxic; Relatively inexpensive in coverage and limited discovery to be effective in the practice of the invention. The preferred watertight material may be applied with a water carrier by simple application to the same back side of the solid patch from which the tile is made. The very light coverage and as a result the low cost of the fluidized water treatment and the simplicity of application make it practical for use in even the tile manufacturer's least expensive product lines. Yo Preferably the base mat or tile is subjected to a high temperature to force drying or maturation of the sald (dc, waterproof material) before the adal water can be absorbed through the core seam. preferably This drying process can be done at the same time as a traditional process step used to dry a polished coating or pigment on the visible side of the slab or plate.

— $ _— Brief explanation. Drawings Figure 1: It is a schematic stereoscopic view of a ceiling slab embodying 1 of the invention; F: is a schematic diagram of a process that uses J to invent . Detailed Description 8 The invention is applicable to different Bala partitions which can be used to cover walls or ceilings. Other images of panels and wall panels include construction panels wall construction panels mainly composed of gypsum LZYPSUM ceiling tiles made of slurry or sle putty and not supported by a thin layer or 01 slats that are not particularly water-repellent useful by the present invention. In describing the manufacture of a ceiling tile incorporating the invention; Reference is made to Figures 1 and from the drawings. A rectangular ceiling ceiling tile (01) is configured to be used as a provisioning panel in a rectangular grid in a suspended ceiling system of a publicly known building. The slab will typically have a thickness between about 11 cm to about 17 mm and nominal planar dimensions alee X adler ; and 1060 are X 0 Vo mm and YOu mm X 103*01 mm or OLAS, metric for these panel sizes. Suspended ceiling panels or tiles are typically made from a felting process or putty Jie Sle water-based pourable formulation The (V+) panel is derived from a water-felting process 0 A typical approximation formulation on a gravimetric basis may include: filler obsidian perlite filler;

M - 708 paper fiber, AY unmodified starch binder, and 0 mineral wool fiber. Mineral wool content can vary greatly; e.g. up to about AYO and in this case of Jie °; Obsidian can be reduced accordingly. In addition to protective fibers; Other sources of cellulose can be used Jie vegetable materials wool or fleece. When these components are appropriately mixed in a water slurry (Sle) and spread on a grid; in Alla a coldly sintered product or similar components are spread face-on in the case of a casting slab; they are dehydrated and/or dried to Solid slab After “cla - 0,” the visible or front side of the execution of the slab or slab is covered with a visible coating or dye, usually a substance consisting primarily of water with some juice or other binder component. In the case of a sade Water felted mat or core The polishing side of the trim may be sanded as necessary to create a flat surface prior to sanding or topcoating Additional prior to applying a sal coat A primer coat may be applied ©0016 which may be composed mainly of lila Vo for example (JE) on the face side of the edge. The tile (01) of Fig. 1 is shown in its composite orientation and has a visible (VY) appearance coating on her underparts; visible face; (VY) primer coat, cwater felted mat or core, and waterproof coating (1); illustrated Lad below; on her face posterior or upper. The visible coating (VY) is typically the finish side of the tile (+ )(¢

A10 —— is a water-based paint with a white pigment color to provide high light reflectivity. It has been discovered that a commercially available water repellent material can be successfully applied to the (V+) back of the tile by coating the mat (VV) with such material. surprisingly; It has been discovered that only relatively small amounts of Jie ° this substance need to be used to achieve satisfactory results. An example of a product suitable for the practice of the invention is a fluorocarbon emulsion such as that sold by Daikin Chemical Europe GmbH, Dusseldorf, Germany under Type 16-1. This product is a water-based emulsion that can be significantly diluted with water while still being effective even when the application rate is inaccurate. Ye The result of diluting the original emulsion is a very light solids water repellent coating of approximately 71 to Yo g/m². Despite this low Jie solids concentration it has been found that an impressive degree of water repellency and prevention is achieved. With the coverage rate of the exposed solids the water droplets on the paint (?1) simply bead and eventually evaporate. Vo illustrates an example of a process for the practice of the invention. A sdryer or dried mat (VT) or board made by a conventional water sintering process with a solids content_ Jie as described above is carried on a transducer (01) conveyor to a spray booth (71) spray booth where (OY) water based top coat or paint is applied facing upwards In this process 0 but when the tile is installed in cin the top coating is facing down

oy - - The bed (VF) is conveyed from the spray booth to the (YY) dryer by means of a roller conveyor (YY) conveyor. A chain of (Y£) sprinkler tubes carrying a set of spray nozzles extends between a pair of (YY) rolls of the conveyor across the width of the conveyor. Spray the sprinkler (V¢) underside of the (VY) underside of the mat with dilute (VE) waterproofing liquid © described above. The (VY) coated with the top coat (11) and the (V€) waterproof material is conveyed by conveyor (Y1) through the dryer (YY) where it is simultaneously Preferred eg drying and/or curing" at a temperature of about 771°C for a holding time of about £0 sec. Other methods of applying topcoat and water sealer are foreseen. eg eal roller or flood coating can be used. Ve condensate dripping from pipes and ducts can fall into the niche or space above a suspended ceiling on the back side of a ceiling slab ceiling tile prior art eventually causing decolorization on the face or face side This mechanism can be attributed to decolorization or dyeing to leaching of the leachate water through the slab 0 tile condensate may be contaminated by surfaces it passes over before reaching the slab (la) . tile Vo when water percolates through the body of the tile ; It can filter a dye-producing substance such as tannin compounds found in paper or cellulose fibers. Contaminated water can seep through the visible paint, staining it. The passage of water is through a slab; a public place where there is a water source; Where it is desirable for the roof slab to be porous to show good sound absorption properties. In addition to the desirable Y. porosity of a typical ceiling tile is the property of being primarily composed of native water which leaves
