Medicinal glass bottles, everywhere in our daily life.
Both beverage, medicine, cosmetics, etc. , medicinal glass bottles are they good partners.
These glass packaging container, because of its transparent aesthetic feeling, good chemical stability, the contents no pollution, high temperature heating, the old bottles can be recycling use of the advantages of, has long been regarded as one of the best packaging materials.
however, in order to compete with packaging materials such as metal cans, plastic bottles, medicine bottles are also constantly improve the production technology, make product quality better, more beautiful appearance, the cost is lower. After the construction of the regenerative glass kiln technology, a second revolution of glass melting technology, which is full of oxygen combustion technology.
in the past ten years, countries around the world in the practice of the technology on the glass furnace show that the total oxygen combustion technology with low investment, low energy consumption, low emissions and other significant advantages. In the United States, Europe, lightweight container is the dominant production of glass bottles, small hole pressure blowing technology ( NNPB) , bottles of cold and hot side spraying technology, etc. , are lightweight production of advanced technology.
it is understood that the German company has been able to produce 1 litre of concentrated juice bottle, weighing only 295 grams, bottle wall surface coated with organic resin, can improve the bottle pressure strength by 20%. Cangzhou composed of pharmaceutical packaging co. , LTD. , as one of the modern professional glass bottle factory, clear consciousness to the production of glass bottles is not easy, there are many scientific problems need to solve.
at present, a kind of colorless, transparent and can block ultraviolet UVA medicinal glass bottles, caused widespread concern. The biggest characteristic of medicinal glass bottles is the ability to see clearly the content of transparency. Because of this, outside of the light is easy to through the container, lead to content material qualitative, degradation. Such as beer from the sun basked a long time, will produce peculiar smell and fade phenomenon. Overseas experiment confirmed that the light wavelength of 406 nm to 500 nm, the beer will be fade until stunk.
abroad recently developed a transparent glass can absorb ultraviolet light. The producing method is, on the one hand, through add absorb ultraviolet light metal oxide in the glass. Use of complementary color effect at the same time, add some metal or its oxide, makes the glass with a color fade.
to the thickness of 3. 5 mm UVA glass and common glass a wavelength of 330 nm light transmittance of random sampling test showed that the common medicinal glass bottle is 60. 6%, while the UVA glass is only 2. 5%. For ordinary glass glass bottles and UVA glass bottles of sun exposure experiments also show that the degradation degree of color and taste the wine is much higher than the latter.
