The problem of bubbles glass stone stripes

Glass bottle glass for many reasons, if you don't reasonable formula, silica content is exorbitant, can increase the content of alumina solve appropriately, and improper cooling too quickly or annealing system is easy to cause internal stress concentration, at some point in the process of rupture, by the way what is your main products? Many literature

as for the glass defects are involved about the following:

glass bottles of defect glass bottles of the inferior quality may be caused by two reasons: the defect of vitreous and products molding and processing system of due process in the process of damage caused by the defect.

the defect of vitreous body is in the process of melting glass homogeneity damage occurring in the course of physical chemistry, in fact, there is no ideal flat glass, industrial glass often have some degree of uniformity, allow non uniformity depends on the purpose of the products made of the vitreous.

in the vitreous defects exclusion is often very difficult, so we must control process, when there is defect in the vitreous immediately after find out the causes of these defects, continue to take measures to prevent defects occurred in a timely manner.

the defect of vitreous different can be divided into three categories: (according to its status 1) Stones ( Crystal inclusions) 、（ 2) Stripe and knot ( Glass inclusions) 、（ 3) Air bubbles ( Gas inclusions) 。
