For glass bottles containing medicinal products, cleanliness is a very important indicator. If there is a trace of impurities, it will affect the quality and efficacy of the medicine. Therefore, the country has a set of strict standards for medical bottles. We produce Manufacturers have also put in a lot of effort in order to eliminate impurities by a large margin!
The medicinal glass bottle is also a medicinal packaging made of glass raw materials. The color of the medicinal glass bottle is brown and transparent. The glass is a semi-solid and semi-liquid substance. Silicate non-metallic material whose viscosity gradually increases and hardens without crystallizing.
In the process of making medicinal glass bottles, due to the effect of the stones and the components in the surrounding glass liquid under a long-term high temperature, the condition of the stones in the medicinal glass bottle will be formed, and the uneven glass liquid formed in the morning will be in the Under the effect of liquid flow and in the process of mixing, it is a fine band formed by being scattered but still dispersed and homogenized.
When the powder is mixed very unevenly, sand eggs are often formed, that is, a siliceous mass is formed. Although the mass is melted into a glass body under the action of long-term high temperature, it fails to diffuse in time and becomes a nodule; due to the layering, the SiO2 The powder is unevenly present throughout, and it forms siliceous streaks after melting. In addition, the grain composition of the quartz grains is improper, and the coarse grains are easy to form streaks.
The occurrence of streaks in glass bottles is caused by the existence of glass bottles with no homogenization, high viscosity and high surface tension in the glass liquid during the blow molding process. Line-to-multiple phenomenon. Now with the progress of technology, this phenomenon is only an isolated phenomenon, but in order to ensure the quality of medicinal glass bottles, manufacturers must make strict selection of medicinal glass bottles before packing and plastic sealing, and remove the unqualified medicinal glass bottles.
