Hollow glass and manufacturing method thereof

Abstract

The invention discloses hollow glass with molecular sieves as spacing bars. The hollow glass comprises a plurality of pieces of glass, a plurality of spacing bars, a first seal, and at least one of a second seal, a third seal and a fourth seal, a spacing bar is arranged between every two adjacent pieces of glass; the spacing bars are arranged on the periphery of the glass in a segmented mode to form a closed spacing frame. The first seal is arranged between the glass and the spacing bar; at least one of a second seal, a third seal and a fourth seal is sequentially arranged on the outer side of the spacing frame, the second seal is located between the adjacent glass, and/or the third seal is located between the adjacent glass or on the outer side edge of the adjacent glass, and/or the fourth seal is located on the outer side edge of the adjacent glass. The fourth seals are located on the outer side edge and the edge portion of the outer surface of the adjacent glass, and the spacing bars are made of molecular sieves. The hollow glass is simple in technological process, high in mechanization and automation degree, short in production period, high in production efficiency and good in product quality, and the service life of the hollow glass can be greatly prolonged.

Description

technical field [0001] The invention relates to the field of hollow glass production, and more specifically relates to a hollow glass with molecular sieve as a spacer and a manufacturing method thereof. Background technique [0002] Insulating glass is a building energy-saving product with good heat insulation and sound insulation performance. Although the structure of insulating glass is very simple, it often occurs in the hollow layer of insulating glass during use, especially in low temperature and cold environments. Fog or condensation occurs, and serious water retention occurs, which greatly affects the thermal insulation performance and visual effect of insulating glass, and greatly shortens its service life. The occurrence of this phenomenon is related to the edge used in insulating glass production There is a very close relationship between internal sealing materials, assembly processes and the degree of mechanized production. Therefore, the key to improving the qua...

Problems solved by technology

[0004] Molecular sieves must be added to the spacer frames of the existing insulating glass as desiccant to absorb the water vapor in the hollow layer and the water vapor entering the hollow layer through the edge of the insulating glass. Generally, the molecular sieve is poured after the spacer frame is completed, and the molecular sieve Molecular sieves will continue to absorb moisture in the environment during the period from pouring to the sealing of the structural adhesive. Since this period lasts for more than ten minutes to tens of minutes, in environments with high humidity, especially in high temperature and high humidity in summer, molecular sieves will A large amount of moisture in the external air is absorbed, thereby greatly shortening its life, thus affecting the service life of insulating glass

[0005] The existing spacers can be divided into factory-made and on-site production according to the production method. The factory-made spacers are finished products, such as aluminum spacers, etc., and then made into spacers at the insulating glass production site. The disadvantage is that it takes up labor. Many, poor heat insulation performance, cannot be mechanized installed on
