Treatment device and process for edge of glass of kitchen appliance

Abstract

The invention discloses a treatment device and process for the edge of glass of a kitchen appliance, belonging to the technical field of glass edge treatment. According to the invention, petal-shaped semi-open sealing rings and waterproof cloth are combined, glass is wrapped in a semi-open fixing mode and is soaked in repairing liquid, and in a vacuumizing environment, the repairing liquid breaks through the petal-shaped semi-open sealing rings and infiltrates into the glass, so micro cracks at the edge of the glass are filled; and after vacuum is removed, the petal-shaped semi-open sealing rings are automatically closed, the repairing liquid is blocked in the glass, after the repairing liquid is dried and solidified, the glass and the repairing liquid form an integral body, and then edge grinding operation is carried out. According to the invention, through the edge treatment process of repairing at first and polishing next, various micro-cracks at different degrees at the edge of the glass can be filled with the repairing liquid, and the contact between the cracks and air, water vapor and the like is isolated, so the micro-cracks are not easy to further extend and expand due to external force, the strength of the glass is effectively recovered, and the use safety of the glass is enhanced.

Description

technical field [0001] The invention relates to the technical field of glass edge treatment, and more specifically, relates to a kitchen electric glass edge treatment device and its technology. Background technique [0002] Glass is an amorphous inorganic non-metallic material, generally made of various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) of. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na 2 SiO 3 , CaSiO 3 , SiO 2 or Na 2 O, CaO, 6SiO 2 etc., the main component is silicate double salt, which is an amorphous solid with irregular structure. Widely used in buildings, used for wind and light transmission, belongs to the mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods. The glass of kitchen appliances is mostly glass i...

AI Technical Summary

Problems solved by technology

The theoretical strength of glass is high, but the strength is low in actual use. The reason is that in addition to the strength reduction caused by glass surface defects and microcracks, edge damage is one of the important reasons for the reduction in glass strength, especially Various defects formed on the edge of the glass after mechanical cutting of the glass, including edge chipping, cracks, cracks, and micro-cracks that cannot be seen by the naked eye. , it will cause damage to the glass

[0004] In order to improve the quality of the glass, the cut glass is usually mechanically polished to reduce the edge burrs and some shallow micro-cracks, but the deep micro-cracks still exist. Due to the brittleness of the glass, these residual Microcracks are easy to break and extend, causing the entire glass to break, seriously destroying the strength of the glass, and making the glass a greater safety hazard
