Glass has transparency height , cuts off nature waiting by force other material incomparable good chemistry stability, use the package container that glass makes to get rid of therefore broad apply to chemical reagent industry , medicine industry apply to health-care food estate out . Health-care food package has plastic , paper , glass , metal etc. , a great variety at present in the homeland. Glass wastages market share take up medicines and chemical reagents package's at present about. 10%, does not worth entire health-care food marketplace 1/3. Simultaneous , make light of since having quality, price is cheap, a variety of outstanding functions such as processing , printing a function well, plastic package has striven for the medical ampulla packing the marketplace part portion in health care medicine. According to expert introduction , in the field of health care medicine package, existence of our country compared with international same kind product certain gap , the material quality being glass mainly. At present, medical glass uses a first rate to expect doing wrapping material already commonly on the international , this Materials Physics function is more stable, chemistry function being able to have an effect to protect medicines and chemical reagents and health-care food. The joint venture and large-scale state-owned enterprise are a few but in our country , except a few besides using first rate material , most enterprise glass package still expects that medical glass manufacturing enterprises gives first place to the material producing grade B also still in using grade B. In recent years, development of industry , medicines and chemical reagents increase by outlet gradually because of our country medicine , the foreign merchant attaches importance to health care medicine glass mass very , sometimes need especially to a few comparatively high price medicines and chemical reagents, vitreous inspect up a centre producing the utensil detecting certificate. That the expert thinks that the cause producing this phenomenon is main, is that the wrapping material promotion cannot keep abreast with, parcel making a livelihood by tiny benefit material enterprise esteems vacancy to "input and output" " making an overall compose in reply foresight.
The department concerned forecasts , our country has material to may cancel usage grade B within 5 years.
Though glass takes As203 , Sb203 as clear agent because of whose comparatively proper characteristic property medicine average health-care food package, but reason glass, therefore in some glass contain As , Sb oxide. Especially PbO , CdO are able to be led into glass middle as the component sometimes,therefore the international or the advanced country is standard, to glass As , Sb , Pd , the Cd be separated out, amounts have clear stipulation equally; Judging from glass products, have problem includes the glass product defect and outward appearance mass at present. But use Er Yan glass to health-care food , refer to the inner surface mainly be able to bear an ability in swimming.If 3.3 boron silicon glass prepares international neuter glass the inner surface is able to bear an ability in swimming being HCI without exception, but our country neuter glass is HCI or HCB then; There exists a few problem in another aspect , medical neuter of our country glass indeed , some may appear to escape from movie if alkali metal separates amounts out comparatively highly. Heavy metal problem is all common existence of international in the homeland's , at present still, there is no the dosages resolving way more well , being able to only be metal by falling off or use other matter replace solve. Judging from medical glass type, our country waits for building medical glass of health care standardizing system urgently. 1997 stipulates at present , between nations standard ISO12775 only somewhat to medical glass available , has international neuter glass , three kinds borosilicate glass , soda-lime glass mainly.Among them, soda-lime glass has not given clear indication of in being an international standard's turn medical, but in other, amounting to 2 steps , being able to be medical in the international standard as long as regulation being able to bear an ability in swimming by that neuter-rization treatment joins 121 ~C. State Drug Administration examines and approves but the glass by the fact that industry stipulates four kinds in the standard in our country in 2003 , our country neuter glass among them makes clear that the limit uses , prioritizes international neuter glass. Glass material quality should be in line with the international conventions. From that glass material quality comes, glass material quality points to the physics and chemistry function certainly mainly , the most important being points to but the chemistry stability.If international neuter glass and 3.3 boron silicon glass pellets law are water-proof may reach grade-1 equally. Our country neuter glass pellet follows water-proof majority but for 1 step , some be 2 steps. If secondary microcosmic looking at an alkali's separates amounts out , is that our country neuter glass is several times bigger than international neuter glass. The expert emphasizes specially , soda-lime glass also has after neuter-rization treatment to material quality a request. In the international standard, require that 121 ~C better than being able to bear or equal to grade-2 , neuter-rization treatment of not all soda-lime glass classics are without exception available doing the package container.
