Daily glass industry belongs to the traditional industrial economy, has a long history, the survival and development of domestic glass industry directly affects the development of people's daily life and related industries, daily-use glass products because of its irreplaceable advantages in the whole social development, will play an increasingly important role

Glass injection bottles are the most common types of pharmaceutical packaging materials in clinical practice.

Glass injection bottles are a common type of pharmaceutical packaging material in clinical practice. Due to the particularity of medicines, the country has stricter requirements on packaging materials. The stability of glass material is a very high-quality packaging material option for drugs that need to be stored for a period of time, so pharmaceutical glass injection bottles are more commonly used clinical drug carriers. The country has issued many standards and policies to standardize and require the quality of pharmaceutical glass injection bottles. Below, Qingdao injection bottle manufacturers combine the new standards for pharmaceutical packaging materials to explain which items need to be tested for pharmaceutical glass injection bottles. What testing instrument to use, the water resistance of glass particles is a routine testing item for glass products. 1. Beat the injection bottle into pieces, put an appropriate amount into the grinding bowl, insert the pestle, and slam the pestle once with a hammer. 2. Transfer the glass in the grinding bowl to the O sieve on the upper layer of the sieve, and repeat the above operation process. 3. Vibrate the sieve with a vibrating screen machine (or shake the sieve manually) for 5 minutes. 4. Transfer the glass particles that pass through the A sieve but remain on the B sieve into the weighing bottle, if the amount is more than 10g, a total of 3 parts are prepared. 5. Use a magnet to remove the iron filings in each glass particle and transfer it into a 250ml conical flask. 6. Rotate and wash the particles of the injection bottle with absolute ethanol at least 6 times, 30ml each time, until the absolute ethanol is clear. 7. Heat the conical flask with glass particles on the electric hot plate to remove the residual absolute ethanol. 8. Transfer to an oven to dry, take it out, cool it in a desiccator, and store it for no more than 24 hours. The above is the testing method organized by Qingdao injection bottle manufacturers. I hope it will be helpful to you, and pay more attention when purchasing.

According to the survey, my country's veterinary drug bottle packaging demand ranks first in the world

According to the survey, my country's veterinary drug bottle packaging demand ranks first in the world. With the government's vigorous promotion of policies to improve the quality of domestic veterinary drugs, the development of veterinary drug bottle manufacturers is also increasing. Because the traditional glass bottle has a high breakage rate, and the inner plug of the glass bottle is not tightly sealed, it is easier to leak, and it will also lead to the accelerated growth of pests and bacteria. In addition, glass bottles are difficult to recycle, which increases the cost of transportation. When plastic bottles are produced by veterinary drug bottle manufacturers, the use of glass bottles is completely replaced. With the development of our country's plastic industry, the veterinary medicine bottle packaging industry will have a very good development prospect. The good product performance and processing method of veterinary medicine bottles are the reasons for their popularity, but when packaging, it is necessary to ensure that the plastic bottles have good pollution-free and cleanliness, and can show good use value in the process of use. The veterinary medicine bottle has high quality bottle quality. The injection blow molding process can not only ensure the consistency and accuracy of the wall thickness and quality of the tube blank, but also ensure the high resistance to permeation, high sealing performance and high quality of the bottle. Appearance properties and sufficient physical and mechanical properties. It makes the bottle mouth more beautiful and tidy, without slope peaks and scraps, the thread size is relatively stable, and the precision is high, the mechanical strength is high, the gloss of the bottle body is relatively good, there are no flow marks and slip marks, and the parting line is very good. Well, there are no weld lines at the bottom of the bottle. The molding characteristics of veterinary medicine bottle: 1. Crystalline material, low moisture absorption, does not need to be fully dried, excellent fluidity, fluidity is sensitive to pressure, high pressure injection should be used during molding. The material temperature is uniform, the filling speed is fast, and the pressure is sufficient. Direct gates should not be used to prevent uneven shrinkage and increased internal stress. Pay attention to the selection of the gate position to prevent shrinkage and deformation. 2. The shrinkage range and shrinkage value are large, the directionality is obvious, and it is easy to deform and warp. The cooling speed should be slow, and the mold is equipped with a cold material cavity and a cooling system. 3. The heating time should not be too long, otherwise decomposition will occur. 4. When the soft plastic parts have shallow side grooves, they can be forcibly demolded. 5. Melt rupture may occur, and it is not suitable to contact with organic solvents to prevent cracking.
