Característiques de les ampolles de vidre medicinal

Entre els 8 productes d'ampolles de vidre medicinals coberts per la nova norma, els estàndards de cada producte es divideixen en 3 categories segons el material i el rendiment. La primera categoria és el vidre de borosilicat, la segona categoria és el vidre de borosilicat baix i la tercera categoria és el vidre de soda calç. Tot i que encara no s'ha produït un determinat producte d'un determinat tipus de material, s'han introduït els estàndards per a aquest tipus de producte, la qual cosa resol el problema de l'endarreriment en la formulació de normes després de la producció habitual dels productes. Tot tipus de medicaments amb diferents graus, diferents propietats, diferents usos i formes de dosificació tenen opcions més flexibles i més grans per als productes i estàndards de diferents materials.

Clarified the definition of borosilicate glass and low borosilicate glass, the international standard ISO 4802. 1-1988 "Water resistance of the inner surface of glassware and glass containers Part 1: Determination and classification by titration" Glass) is defined as glass containing 5-13 percent (m/m) of boron trioxide (B-2O-3), but ISO 12775 "Classification of Glass Composition and Test Methods for Normal Mass Production" issued in 1997 In the definition of borosilicate glass (including neutral glass) containing diboron trioxide (B-2O-3) greater than 8 percent (m/m). According to the principles of glass classification in 1997 international standards, the B-2O-3 6 percent (m/m) glass material widely used in China's pharmaceutical glass bottle industry for many years should not be called borosilicate glass or neutral glass. Tests have proved that some of the glass particle water resistance and inner surface water resistance tests of this type of material are not up to level 1 and HC1, or are at the edge of level 1 and 2. Practice has also proved that some of this type of glass will have neutral failure or peeling during use. However, this type of glass has been produced and used in China for many years. The new standard retains this type of glass and stipulates its B-2O- The content of 3 should meet the requirement of 5-8 percent (m/m), which clearly defines that this type of glass cannot be called borosilicate glass (or neutral glass), and it is named low borosilicate glass.
