Introduction of quality inspection methods for veterinary medicine plastic bottlesThe plastic bottles of veterinary drugs are mainly used in the packaging of drugs. Many of the packaging of veterinary drugs in the market are plastic bottles. No matter what packaging is related to the safety of drugs. Therefore, each manufacturer of veterinary drug bottles should carry out certain quality tests, and also carry out more reasonable tests on the appearance and size, so that the production of veterinary drug bottles can meet the relevant standards, And there will be no major accidents during use.First of all, the measurement of the wall thickness of each part of the plastic bottle of veterinary medicine: if the plastic bottle of veterinary medicine is a circular rotating body, the symmetrical part of the measuring area should be cut with a knife, so that the measurable tool is the location of the measuring points of each part of the bottle body, and the thickness of the plastic bottle of veterinary medicine, the thickness of the body The symmetrical part between the thickness of the shoulder and the thickness of the bottom of the bottle shall be strictly tested, and its maximum and minimum ＆#118alues shall be recorded. Then, the tolerance of its size shall be checked against the design drawings of the bottle body product to see if it is within the standard range. The physical and chemical properties of plastic bottles of veterinary drugs are mainly tested for heavy metals, non-volatile residue, reducing substances and sealing properties. For the measurement of the diameter of the outer side of the plastic bottle of veterinary medicine, the main measurement method is to use a vernier caliper. The measuring surface contacts the measuring place of the largest outer diameter of the bottle body. The vernier caliper is tightly disturbed. After that, the plastic bottle of veterinary medicine is rotated 360 degrees, and the maximum and minimum ＆#118alues are recorded. The error should be controlled within the range of 0.1mm. Measure the outer diameter of the mouth of the veterinary medicine plastic bottle: the main measurement method is to span the measuring tool scale across the center of the bottle mouth, and avoid the position of the mold closing line of the bottle body. For the position of the main shaft directly close to the thread, rotate the circular bottle mouth 360 degrees, measure its maximum and minimum ＆#118alues, and compare with the design drawing of the bottle body, The error of outer diameter should be controlled within the range of 0.1. To sum up, the detection of plastic bottles of veterinary drugs is very precise, and the size control range is very small. Therefore, great attention should be paid to the production process of plastic bottles of veterinary drugs. |
