TH9201B - Processes and equipment for glazing hollow vessels By means of inorganic masking with the use of plasma - Google Patents

Abstract

Application of thin inner coating inside plastic containers. Or metal with the use of plasma This can be carried out with the use of inert inert inorganic substances such as insoluble silica or metal oxides, or By using a mixture of substances such as metals, metal oxides, metal salts and carbon or organic radicals, to form a flexible crystal lattice. Or by using different layers of those lattice This technology involves Placement of containers within airtight enclosures Placing the vapor generator Which is filled with the inert inorganic material of the pre-defined elements inside the container Vaporization of the material already mentioned Creation of the aforementioned vapor plasma And thin coating of the material already mentioned On a pre-defined area of the inner surface of the said container Where the particles of the said coating High temperature Can penetrate into the skin already mentioned Due to the thermal energy of those particles But does not increase the temperature at the entire surface Due to the small mass flow
