Chinese medicinal glass quality and international standards of study – the glass
Glass with other materials can not match the fine chemical stability, so the packaging container made of glass are widely used industrial chemicals, Medicine Industrial, Food Beverage and wine industries. Medicine is not only oral but also the injection, so the quality of such containers not only affect Drug Quality But also relates to personal safety. Glass container industry in the Chinese pharmaceutical packaging glass containers are the highest technical specifications, safety and health requirements of the most stringent product of the production of such products must obtain state registration certificate. International pharmaceutical glass containers on the quality of both the provisions and requirements more clear. This will be how the quality of Chinese medicinal glass to explore with international standards and research.
Medicinal glass of quality and international standards of
One of Medicinal glass quality and the need for international standards
1, is the export of drugs and medicinal needs of the glass
Because our medical industry, pharmaceutical exports is increasing. Foreign drugs used glass packaging attached great importance to quality, in particular, higher prices for some drugs, some pharmaceutical companies come to us so often of glass quality inspection centers for testing and issue a certificate. In fact the neutral country can only get a handful of glass have been built with the assistance of national recognition of glass. Really strict accordance with international neutral glass is unqualified. So, to export drugs, medicinal glass quality and international standards is imperative.
2, is to further protect the health needs of our people
As improving the lives of our people and culture, improving the quality of people's health awareness has increased significantly. On the other hand, China's pharmaceutical neutral glass does still exist some problems, such as precipitation amount of alkali metal higher, some may appear off-chip. Heavy metals in the past, pharmaceutical glass on some control. With the development of technology, should now be on the quantitative control of heavy metal, respectively, in order to protect the health of our people.
2, with the possibility of international standards
China is currently in rapid economic and technological development, accelerate the pace of reform and opening up, a period of expanding trade. Pharmaceutical glass are also on the upswing. Particularly through the national system, the State Drug Administration to strengthen administrative functions for our pharmaceutical glass for a short time to reach the international advanced level or basic created very favorable conditions.
3, where several aspects and international standards
1, from a medicinal glass types and international standards
International standard ISO12775-1997 has made it clear there are three main medicinal glass:
international neutral glass a = (4-5) × 10-6k-1.
3.3 borosilicate glass (3.3 ± 0.1) × 10-6k-1.
soda-lime glass (8-10) × 10-6k-1. Soda-lime glass is not in the specified international standard medicine. However, the provisions of other international standards as long as the processing by the neutral and water resistance up to 121 2, can be medicinal. In China last year, the State Drug Administration approval of a "medicinal glass composition Classification and test methods" industry standard provides four types of glass, which restricted our neutral glass clear. Focus on the development of international neutral glass.
2, from the glass with international standards
Glass of course, refers to physical and chemical properties, but the most important is the chemical stability. Such as international neutral glass and borosilicate glass particles France 3.3 water can reach one. But our neutral glass particles, most of a water law, some for the two. Alkali from the micro to see if the precipitation amount, then our neutral glass several times bigger than the international neutral glass.
Soda-lime glass by the neutral handling of the material is also required. International standards require 121 water is better than or equal to 2, not all soda-lime glass processing can be done by neutral medicinal containers.
