It is mainly used in medical, chemical packaging and other industries. Different industries have different requirements for pharmaceutical aluminum plastic composite cover.
More understanding of the medical aluminum plastic composite cover, to analyze the traditional pharmaceutical aluminum plastic composite cover treatment methods.
1. Use electric oven to process the oven.
The principle of dry heat sterilization: the use of thermal factors to oxidize and change the protein through dehydration and drying.
It is a kind of physical disinfection and sterilization method that causes the death of microorganisms by means of sex, carbonization and electrolyte concentration poisoning.
The temperature is maintained for a period of time to achieve the purpose of killing microorganisms. In the past, the use of a two-leafed oven for common pharmaceutical aluminum composite covers was only removed.
Aluminum cover the surface of oil, and corresponding disinfects processing. In recent years, there are also will build into medicinal lu: su composite hot air circulation oven to 120 ℃ heat preservation 2 h sterilization process.
Although this method can achieve the sterilization effect, it is not suitable for the sterilization treatment of the pharmaceutical aluminum composite cover.
2. Uv irradiation treatment.
By irradiation of ultraviolet light, destroying and altering the DNA of microorganisms (deoxyribonucleic acid), causing bacteria to die instantly or not to reproduce,
To achieve the purpose of sterilization, ultraviolet sterilization belongs to pure physical disinfection method, it has simple and convenient, broad spectrum efficiency, no secondary pollution, easy to manage and.
To realize the advantages of automation, ultraviolet lamp tube is usually installed in a certain space for disinfection.
The amount of irradiation needed for a living organism. When used to disinfect the plastic composite lid (including aluminum cover), it is usually used to remove the aluminum cover and disperse it in the disinfection area to use ultraviolet light.
Irradiation 2-} 12 h to achieve disinfection purpose. Due to the intensity of ultraviolet radiation and the square of irradiation radius.
3. Method of treatment with stink stage sterilization.
The molecular structure of ozone at normal temperature and atmospheric pressure is unstable. It will soon decompose itself into oxygen and single molecule oxygen atoms. The latter has strong activity.
There is a strong oxidizing effect on bacteria, which can destroy the cell membrane and kill it, and the extra oxygen will be recombined to become normal oxygen, which does not exist.
Any toxic residue is a pollution-free disinfectant.
4. Treatment with ethylene oxide sterilization method.
The alkylation of ethylene oxide, which can be used in the presence of alkylation of amino < -cooh, amino < -nhz), thiohydroxy (-sh) and light base < -oh,
It causes the protein to lose its genes, blocking the normal chemical reaction and metabolism of the protein, leading to the death of microorganisms.
Bioenzyme activity. The penetration of ethylene oxide is very strong, which can penetrate micropores to achieve the corresponding depth in the product, thus improving the sterilization effect. At present.
Epoxy ethane is widely used in medical devices to sterilize.
5. Method of treatment with medical aluminum plastic composite cover cleaning machine.
Based on the principle of wet and heat sterilization, the article kills microorganisms in the sterilizer by using pressure steam or other wet and heat sterilizing medium, which is the most in thermal sterilization.
The most extensive method is effective and widely used. Due to the high latent heat of saturated water vapor and strong penetration, it is easy to make protein denaturation or coagulation, which not only sterilizes the effect.
Depending on, and also can reduce the sterilization temperature, reduce the action time, is the drug preparation production process commonly used sterilization method.
