â Mobile Phone: +86-13112253528 Float glass is manufactured by allowing the glass from the tank furnace to flow across a bath of molten tin in a controlled atmosphere of nitrogen and hydrogen which yields transparent glass sheet, the surfaces of which are flat and parallel so that they provide clear, undistorted vision and reflection. Top rollers, stretching forces on the glass ribbon and vibrations from outside induces a corrugation of the glass surfaces. A clear separation of the hot melting part and refining part and of the working end is not possible. It is often processed to suit many different applications and requirements. We specialize in the producing of 0.3mm-2mm thick float aluminum mirror, float glass, 2X magnifying glass, 2X rearview mirror and which regular sizes are: 1220*914mm, 1245*1092mm and 305mmX407mm, etc. GlassInspect for float glass inspection is used for local defect detection, including for example: We provide specialist analysis of bubble defects in glass utilising our portable bubble gas analysis system. 3 . The width and thickness of the glass ribbon is controlled by the rate at which the glass is pulled through the tin bath. FLOAT GLASS QUALITY SPECIFICATIONS FOR CAPTURED GLAZING Quality Assurance: Glass is divided into three zones. Point defects and surface defects should be assessed as for float glass and Hammerglass. In fact nearly all flat glass products are now made from float glass. ... variation of n( σ) for the two float glass surfaces in comparison with polished plate glass. For over twenty years, Dark Field Technologies has been leading the glass surface inspection industry with a glass inspection system of new laser and camera inspection and glass coating defect detection technologies, including retro-reflective laser systems for float glass inspection and telecentric lasers and cameras for low-e glass and display glass. Remedies offered hopefully give you a basic understanding of defects and their causes. The differences in the glass defect potential of the interaction between fused-cast AZS and different glass melts computed by this method, agrees with the amounts of bubbles and knots found in industrial produced TV glasses. By switching between different camera channels and illumina-tions, multiple images of a defect can be taken, analysed and finally classified with a much higher grade of accuracy than systems with a single defect image can. Float Glass Inspection and Measurement for Highest Quality and Optimized Yields. Since the throat does not exist, it is merely one furnace which is very large. 3 Zone A Glass defects Glass defects are defects that result from the manufacturing process of the float glass. The float process is now used almost universally for production of glass. Image filtration based on gradient direction is used to filter noise and reserve the source information of defects. You can resolve defects quickly while maximizing production efficiency. contact with a glass melt, the mechanism of knot and bubble formation and the parameters that influence this mechanism. The defects of coated glass and solutions Off-line (soft coated) magnetron sputter coated glass can be divided into two categories: solar control glass and low e glass. Edge quality plays an important role during fabrication, shipping and installation of float glass products in automotive and architectural applications. Float glass is manufactured by allowing the glass from the tank furnace to flow across a bath of molten tin in a ... 3.8 Linear and final Defects - Defects on the surface or inside of the glass such as the non-uniformity of the base, scratch etc. The present invention is a method for reducing the defect density of glass produced via a float glass process which is well known in the art. Can be seen but not felt. We specialize in ultra-thin mirror glass, 2X magnifying glass and rearview mirror in various sizes and shapes as customers required. The potential causes of an outbreak are wide ranging. One unusual stone defect in a pattern glass was recently discovered, and a scrupulous methodology was necessary to investigate its source. Glass Ribbon Inspection In some instances, several remedies may be needed to correct the causes. In the press and blow forming, if a plunger and mould are out of alignment, or heated to an incorrect temperature, the glass will stick to either item and become torn. â Address: No. … Of three kinds of screening particle size, should be carefully check. The defects of coated glass and solutions. The molten glass is floated onto a bath of molten tin, forming a perfectly flat surface, and a ribbon that is naturally approximately 6.5 mm thick. Gridbots Glasso is integrated machine vision solution for online float glass inspection. This method inspects defects through detecting the change of image gray levels caused by the difference in optic character between glass and defects. This kind of defect is considered feldspar melting quality problems easily. During a single scan pass, multiple images are generated for comprehensive defect analysis. When a glass container fails on the customer’s filling line because of a manufacturing defect, the reputation of glass suffers, which results in a loss of customer goodwill. The fake defects (insects, dust, etc.) It uses latest machine vision technologies to identify defects above 100 microns in real time.The system is applicable for solar, float and sheet glass. In order to improve quality of float glass and quality grade division, it needs in-line automatic detection for float glass. The batch must be carefully controlled in order to generate a glass with a composition which meets the requirements of EN 572-1:2012 and conforms to SGG UKs own internal standards. Make-up mirror glass is self-plate glass by silver coating and protective paint treatment, after two drying made of these raw materials. Common glass defects include bubbles, stones, knots, cords and cat scratches. The molten glass will exit the furnace at approximately 1000 o C. THE FLOAT BATH.
