Description
prooeas of fused oa carrier 2 invention relates to processes for the facture of preferably coatings on carrier of artificial wherein the coating is formed a melt of the inorganic It is known tha carrier natural or artificial can be coated with a glaze in that the glazing composition and a flux are applied to the stone surface to be or are tained the outset in the surface of the concrete or stone and is melted into the surface by means of a similar In the performance of this and in all of which the glaze composition of a metallic or ceramic nature such as glass or other silica is first applied to the surface as an emulsified then dried and there arises the difficulty of producing a uniform coating on the Special experience and skilled operators are required in order to apply the glaze to the carrier without faults and to make sure of the uniformity necessary the production of a continuous coating of constant Some of these known processes have not become adopted practice on any considerable because they have been found too costly and consuming owing to the special care with which the tion to be melted has to be applied to the There the danger that the flame used for melting down the composition blows away the composition or at least thickness of the 3 patent compound bodies comprising one layer of a carrier body hairing a heat conductivity of not more tha 2 and consisting of artificial stone r an organic and being suitable heat or sound Insulation or as a and one coating formed out of a melt of especiall ceramic composition having a melting point above are in that the is kept at room temperature without being heated and the molte which may be is allowed to the surface of the from the state of melt into the final solid has the to provide an altogether different method of applying surface coating to a which method is intended to suit the conditions of industrial operation and to be capable of being used on a vide which reliably produces a compound body of good quality requiring specially skilled labournor special arrangements or According to the main feature of the a mixture of a preferably an organic such for synthetic or the and a inorganic coating is applied at a temperature below the melting point of the inorganic coating material to surface of a carrier then heat is applie to the by a by radiation or by a hot for removing the binder and fusing the coating whereafter the coating thus 4 produced solidified on the carrier by spontaneous or positive The heating operation under oxidise at least some components of the coating It is thus a essential of the invention that the coating material to be applied the carrier body is admixed with a binder does not produce a melt but serves to bind the components of the coating material which are to be applied to the carrier bod by being melted to and to with that coating a coating mixture as a has a pasty or more or less liquid mixture can readily be spread and distributed the sur ce of the carrier body in a layer of uniform For purposes of the invention the way in which the binder is ultimately disposed is It for be or be so that i is converted into a physical or chemically bound ingredient of the solidifying ing it s possible to enhance the adhesion of the coating mixture to the of the carrier body by additional or to forego such additional this within the scope of this Such additional means may for the use and heating of a thermoplastic substance on the carrier surface be the coating mixture is melted invention provides many advantages as compared 5 with known processes such as those set out Among others there the advantage that the coating mixture can be prefabricated as a preferably a pliable which can be applied to the surface to be coated and heated in situ by a thermal operation affecting merely this foil and the surface beneath ith this embodiment of the invention the uniformity of the laye o the coating mixture of predetermined and safely achieved by the selected thickness of the which can be achieved with great precision by the industrial of the This facilitates greatly the operations to be performed in situ for melting the coating material on to the carrier and the time and labour requirements of these operations are lowered process according to the invention can be simplified even further if not only of coating mixture is pre bricated but also a coating In this case the foil consisting of the coating mixture is first applied to temporary oarrier surface and melted whereby a coating layer or film consisting of the inorganic coating material is allowe to then detached from the temporary carrier surface finally when and where required applied to the permanent carrier The adhesion of the coating layer the permanent carrier surface be in various thermally or by glueing or In this process the temporary carrier serves merely as a 6 kind of last or recoverable mould and it is so designed that it imparts to the inorganic coating layer or film the desired shape and She advantage of this embodiment consists mainly in that both the composition of the inorganic coating including such desired properties as colour and the and its thickness can be predetermined very this removes any danger of inaccurate and faulty work in the operation of applying this layer to the permanent carrier This is of especial advantage in those cases where the coating is formed of a very thin yet formly continuous film of a valuable and this process achieves both a considerable saving of the material and a technically faultless protection of the coated invention illustrated by the following example to which it is not The inorganic coating mixture was a powder of grain size smaller than composed parts b o ZnO 5 The binder was a mixture of 8 parts by weight of highly disperse polyvinyl acetate with 35 parts of 7 coating inixtiire was highly viscous became in the course was applied to the surface to be coated by means of a pneumatic spray then melted oh to surface by means of an this thermal Operation the surface up very slightly only beneath t e coating layer initial thickness was about and thus was not temperature within the carrier 4 mm beneath the coated surface was about mixture fed to the blow pipe is pre erabl so composed that its combustion temperature is about A combustio chamber can be provided in the spra gun which can thus serve as a blow In substantially the same manner it is possible to a foil of the coating material a er being detached f rom its temporary can be applied to the permanent carrier surface by fusing or temporary carrier have a smooth a ferred temporar carrier is constituted by a steel temporar carrier is initially covered first with an then the coating composition is sprayed on to that heated and After solidification the prefabricated foil is withdrawn from the steel It can be fused or glued on to the permanent insufficientOCRQuality
