Glass production technology products, glass bottles

The first way is the flame polishing, the use of flame on the surface of a glass container for softening baking, thermal impact, can remove some twill on the surface of the glass container, wrinkled skin, many of the hollow glass containers are mouth after cutting mouth fire polishing,, but this kind of treatment method can reduce the glass surface roughness, also afford to fry, applicable glass of soda lime glass, high borosilicate glass.

in glass production process, have to polishing technology of several kinds of glass bottle, glass bottle is the use of physical or chemical method is a multi-layer composite, give priority to with PET, join the PEN of other air tightness good materials for 3 or 5 layer bottles; The second is the use of special processing methods, such as in PET bottle, or the outer coating epoxy blocking layer, or plasma treatment; Three is to use other barrier property resin molding, PEN or PEN copolymerization or blending with PET as raw material, can not only improve the Yin gas bottle, heat resistance and improve the bottles, you can also alkaline cleaning disinfection, repeated use, thereby reducing costs, because the former two methods have poor transparency, recycling setbacks, special subject headings such as process complex, equipment required, and although increased air tightness, but poor heat resistance, can adapt to the occasion of aseptic filling.
