High-penetrating agent and preparation method thereof

Abstract

The invention discloses a high-penetrating agent and a preparation method of the high-penetrating agent. The high-penetrating agent comprises, by weight, 0.05%-1.0% of surfactant, 2%-8% of organic solvent, 0.05%-1.0% of pigment, and the balance water. The surfactant is anionic surfactant or nonionic surfactant. The invention further provides the preparation method of the high-penetrating agent. Experiments show that the high-penetrating agent is good in detection effect of tightness of pull ring cutting mark and welding of a plastic infusion container, and capable of shortening the detection time. Particularly, the welding tightness of semi-finished products can be directly detected, the detection period can be controlled to be within two hours. The above advantages bring great convenience to adjustment of equipment and the technology on production site, reduce detection cost, and greatly reduce potential quality hazard caused by detection errors of the products.

Description

technical field [0001] The invention relates to a penetrant and a preparation method, in particular to a high penetrant for testing the tightness of plastic transfusion containers and a preparation method. Background technique [0002] At present, plastic infusion containers are commonly used in clinical infusion, which are composed of plastic infusion bags and polypropylene combined caps (ring-pull type) through welding. The main component of the infusion solution is water. Under the effect of surface tension, the surface wettability between the solution and the plastic infusion container for infusion is poor. In the case of micropores in the plastic infusion container for infusion, the solution is not easy to seep out under the action of external force. , and after about 7 days of storage, the liquid medicine will seep out in a small amount, and there is a great quality hidden danger. At present, the only penetrant used to check the tightness of plastic infusion container...

AI Technical Summary

Problems solved by technology

[0003] When the above-mentioned prior art detects the tightness of plastic infusion containers, micropores are difficult to detect or cannot be detected, and the time required for detection is long, which affects the inspection cycle and quality control of products.

When detecting the welding micropores of PP packaging materials, the external force must overcome the surface tension of the liquid on the micropores under pressurized state. Usually, it takes 2 days to find the micropores, but even so, there are still undetectable Case

Moreover, this detection method can only be used for the detection of finished products. It must be a finished product that has been filled and after sterilization and disinfection, it can only be detected under the condition of applying external force.

This detection method lags behind the actual production. After the detection results come out, a large number of finished products have been produced. If there are micropores, all finished products must be reworked, which wastes a lot of manpower and material resources, and there is a great quality hidden danger.
