In borosilicate glass ampoule registration certificate

2015/4/19      view:
Warmly congratulate Yangzhou Dasheng medicinal glass limited company successfully passed the State Food and Drug Administration issued, "in borosilicate glass ampoule bottle" registration certificate
The difference between low boron silicon and boron in silicon ampoule
The 1 most important difference is that the chemical properties: low borosilicate vials of national standards in surface water is 2.6mm, the national standard of boron in silicon surface water in the bottle is 1.3mm, simply say "adsorption in the bottle wall of potassium and sodium and water bottle in the bottle factory" is the following process of alkaline oxides harm, the less the better oxide resistance, resistance to drugs of PH, pH, clarity, stability and other indicators are very good.
2: the physical properties of boron in small size tolerance is very small, such as the 16 pipe diameter tolerance is plus or minus 0.14mm, color crystal clear, very good, strength, and better production equipment; low borosilicate tolerance and batch instability, such as pipe diameter tolerance of plus or minus 16 standard is 0.3mm, color is green, it is difficult to with imported equipment and high-end equipment matching.
The main difference between the 1, identification of neutral glass with low borosilicate glass, soda lime glass is that it has very good thermal stability and chemical stability, thermal expansion coefficient and the content of online three oxidation two boron with high boron silicon glass is not the same. Therefore, identification of the project as:
(1): coefficient of linear thermal expansion is one of the main physical properties of glass, which determines the thermal stability of the glass, the glass can withstand ability is the drastic changes in temperature, and the coefficient of linear thermal expansion is mainly determined by the chemical composition of the glass. Therefore, the coefficient of linear thermal expansion as the identification performance, using the properties of glass can be controlled, and can reflect the type of glass composition. The linear thermal expansion coefficient of neutral glass is less than 5 * 10-6K-1 (20 DEG ~300 DEG).
(2) three two boron oxide content: it is the main component of glass to improve the thermal stability and chemical stability, but also in a certain range, with the content increasing, the better the performance of the glass. Therefore, the three oxidation two boron content as differential item performance, can control the glass, and can reflect the type of glass composition. The content of B2O3 in the neutral glass for not less than 8% (g/g).
2, 121 C particles water resistance methods of glass particles in the determination of resistance to water of 121 DEG C method and classification (YBB00252003), according to the material performance index as 1. The control of chemical stability of glass.
Method for the determination of glass particles at 98 C, 98 C water resistance by using 3 particle water resistance method (YBB00362004) were measured. 98 C particle method is an important method of water resistance, widely used in the inspection of glass water resistance performance of the classification of fine, a wide range of. Neutral glass material should be consistent with HGB1 requirements. The control of chemical stability of glass.
4, hydrolytic resistance of the interior surfaces using the method of 121 DEG C surface resistance test method and classification (YBB00242003), the index reached the requirements of HC1. The chemical stability of glass bottle.
5, acid proof glass can withstand the test of the degree of acid etching, to quantitatively determine the acid level. The first method for the gravimetric method, according to the method of determination of resistance to boiling hydrochloric acid etched glass (YBB00342004) method for the determination of the first, according to the weight loss per unit surface area of glass to determine the level of. Neutral glass shall conform to the requirement of grade 1. The second method for flame spectrometry determination of resistance of glass, in accordance with the boiling hydrochloric acid etching (YBB00342004) method for the determination of second. According to the basic oxide glass unit area precipitation gauge to determine whether qualified. Neutral glass should be less than or equal to 100 g/dm2. The chemical stability of glass bottle.
6, the alkali resistance of glass can withstand the test of mixed alkali erosion degree, to quantitatively determine the level of alkali glass. Methods according to the method for the determination of resistance to boiling water solution of glass etching mixture (YBB00352004) assay, neutral glass shall conform to the requirement of grade 2. The chemical stability of glass bottle.
7, the internal stress measuring method using stress index (YBB00162003), (GB 2637-1995) use ampoule. Horizontal annealing process control of glass bottle.
8, the circular runout measuring method using vertical axis deviation (YBB00192003), were use ampoule (GB 2637-1995). Control of container bottom surface smoothness and the overall symmetry.
9, the breaking strength of the ampoule method (GB 2637-1995), followed by the ISO9187-1:2000 index (E). To ensure the use of requirements, prevent breakage.
10, arsenic, antimony, lead, cadmium leaching method using test method of arsenic, antimony, lead, cadmium leaching amount (YBB00372004), arsenic, antimony, lead, cadmium leaching content limit is: As = 0.2mg/L; Sb = 0.7mg/L; Pb = 1.0mg/L. To ensure the safety of the use of the ampoule. According to a 2005 review meeting decided to increase the leaching of cadmium content limit: Cd = 0.25mg/L.
