How To Avoid Glass Bottle Defects In Production

The defects of glass products can be divided into two categories: the defects of the glass itself and the defects caused by the forming and processing of the products. This chapter discusses the defects of the glass itself.

Glass body because there are all sorts of sundry, cause the destruction of the vitreous uniformity, from store the batch of material processing, preparation, melting, clarifying and homogenizing, cooling and in the process of forming and cutting production process system of bad or errors in the process of operation, will cause the production of various kinds of defects, defects make the glass quality is greatly reduced, Even seriously affect the further shaping and processing of glass bottles, or cause a lot of waste. In practice, ideal, uniform vitreous bodies are rare, and the degree of permitted heterogeneity depends on the use of the articles made of the glass. For this optical art glass and many special industrial glass, put forward high requirements, for the general use of glass is relatively low requirements.

The types and causes of vitreous defects are various, it is not very simple to find out the causes of defects, and it is also difficult to eliminate them. Because the occurrence of vitreous defects is closely related to the melting process of glass, similar defects may be produced by different reasons at different stages of the melting process. Therefore, the process must always be strictly controlled to prevent defects as far as possible. The defects of vitreous bodies can be divided into three categories according to their different states: Bubbles (gas inclusions), stones (solid inclusions), stripes and nodules (glass inclusions), these defects are internal defects. Appearance defects are mainly produced in the process of forming, quenching and cutting, etc., mainly including optical deformation (tin spots), scratches, end defects (burst edge, concave and convex, missing Angle), etc

Send different kinds of defects, its research methods are also different, when some defects in glass bottles, often need to pass a number of methods of joint research, in order to correctly judge. On the basis of identifying the cause. Take effective process measures to prevent the defect from happening.
