Yingtai: Effect of Different Sterilization Methods on The Chemical Properties of Materials

Yingtai: Effect of different sterilization methods on the chemical properties of materials

The effects of different sterilization methods on the chemical properties of materials are as follows:

1. High temperature sterilization method (such as steam sterilization)

Chemical properties of the impact:

1. polymer materials: high temperature may lead to thermal degradation of polymer materials, change its chemical structure, mechanical properties and physical properties. ★ Paper-plastic materials: paper-plastic materials may lose their original physical properties at high temperatures, for example, paper may become brittle and plastic parts may be deformed.

2. Chemical sterilization (e.g. use of ethanol, iodophor, peroxide, etc.)

Effects of chemical properties: ★ Organic materials: chemical disinfectants may react with organic materials, resulting in changes in the properties of the material, such as changes in color, texture or structure. ★ Sensitive materials: Some chemical disinfectants have a corrosive effect on sensitive materials, which may result in damage to the chemical properties of the material.

3. Ultraviolet Sterilization

Chemical property effects: ★ Polymer materials: UV light may cause the molecular chain of polymer materials to break, changing the chemical properties of the materials. ★ Sensitive materials: UV rays may cause photochemical reactions to some sensitive materials, thereby affecting their chemical properties.

4. Plasma sterilization method

Chemical Properties Impact: ★ Polymer materials: plasma sterilization has less impact on the chemical properties of the material, but may cause certain chemical changes to sensitive materials. ★ Inorganic materials: plasma sterilization has a small effect on the chemical properties of inorganic materials, but may change the chemical composition of the material surface. Comprehensive Consideration

When selecting a sterilization method, the possible effects of the sterilization method on the chemical properties of the material must be taken into account. For example, for materials that need to be stored for a long period of time, high-temperature sterilization methods that may cause changes in material properties should be avoided. For sensitive materials, the sterilization method that has less impact on the chemical properties of the material should be selected, such as plasma sterilization. At the same time, for certain materials for specific purposes, such as medical nonwoven or paper-plastic packaging materials, special attention needs to be paid to their stability under different sterilization methods to ensure the sterilization effect and long-term effectiveness of the material.
