Abstract

Belonging to the technical field of building materials, the invention relates to a processing technique for a bent aluminum strip double-silver LOW-E hollow glass. The process includes the steps of: cleaning and drying double-silver LOW-E glass and tempered glass respectively; calculating the aluminum strip length according to the glass size and glue depth, bending the aluminum strip and conducting filling with a drying agent, welding the joint to obtain an aluminum frame; coating both sides of the aluminum frame strip with butyl rubber evenly; putting the double-silver LOW-E glass on one side of the aluminum frame strip coated with butyl rubber, putting the dried tempered glass to the other side of the aluminum frame strip, laminating the two glass sheets into a hollow glass primary product; conducting secondary sealing on the hollow glass primary product with polysulfide rubber or structural silicone rubber, and finally carrying out curing to obtain the bent aluminum strip double-silver LOW-E hollow glass. Being simple and practicable, the processing technique provided by the invention reduces the moisture permeability of hollow glass joints, endows the prepared glass with high bending strength and impact strength, and further prolongs the service life.

Description

technical field [0001] The invention relates to a processing technology of glass, in particular to a processing technology of bending aluminum strip double-silver LOW-E hollow glass. Background technique [0002] Insulating glass has been widely used in construction and other fields. In addition to extensive use in construction, the use in other industries such as railway transportation and refrigeration industries is also gradually increasing. With the expansion of the application range of insulating glass, higher requirements are put forward for whether insulating glass can guarantee long-term and effective use. Although there is no clear regulation on the effective use time of insulating glass, those skilled in the art actively take various measures to ensure that the effective use time of insulating glass is long enough to meet the needs of various purposes. [0003] Insulating glass consists of two or more pieces of glass, separated by a spacer in the middle, and seal...
