Why does alcohol corrode plastic acrylic material?

Alcohol does not corrode plastic acrylic.

Material (also known as acrylic material). Because the acrylic material has strong stability and is resistant to a variety of chemicals.

Acrylic material has good transparency, chemical stability and weather resistance.

It is easy to dye, easy to process, and has a beautiful appearance, and is widely used in the construction industry. Plexiglass products can generally be divided into pouring plates, extruded plates, and molding compounds.

The common acrylic products are acrylic products that are assembled from raw materials such as acrylic granules, plates or resins through various processing methods and with a variety of parts and accessories of different materials and functions. As for the acrylic fiber, acrylic cotton, acrylic yarn, acrylic nylon, etc., which are commonly heard, they refer to acrylic acid.

Polymerized man-made fibers.

It is not related to acrylic products.

Acrylic is corroded by alcohol, mainly because plasticizers (DOP ·DBP) are added to the acrylic sheet, which do not participate in chemical reactions during the polymerization of acrylic.

Acrylic, also known as PMMA or acrylic, is derived from the English acrylic (acrylic plastic). The chemical name is polymethyl methacrylate, which is an important plastic polymer material developed earlier, with good transparency, chemical stability and weather resistance, easy dyeing, easy processing, beautiful appearance, and has a wide range of applications in the construction industry. Plexiglass products can generally be divided into pouring plates, extruded plates, and molding compounds.

In principle, alcohol is almost non-corrosive to acrylic, and we usually see that acrylic is corroded by alcohol mainly because plasticizers (dop · dbp) are added to the acrylic sheet, which does not participate in chemical reactions in the acrylic polymerization process, so it has oil absorption, and alcohol will dilute the plasticizer when it comes into contact with plexiglass. After the plasticizer comes out, the plexiglass that we usually see is corroded.

It has a certain solubility.

Alcohol doesn't do much harm to plastics.

The effects of alcohol:

1. To avoid being eroded by microorganisms.

Alcohol is often used to wipe ultraviolet lamps. This alcohol is commonly used in hospitals, but in the home it is only used for the cleaning of camera lenses.

of alcohol is used for disinfection. This is because too much alcohol will form a protective film on the surface of the bacteria, preventing it from entering the bacteria, making it difficult to kill the bacteria completely. If the alcohol concentration is too low, it can enter the bacteria, but it cannot coagulate the proteins in the body, and it cannot completely kill the bacteria.

50% alcohol prevents pressure sores. For example, a little 40% of 50% alcohol is poured into the hands during massage, and the patient's pressure part is massaged evenly, which can promote local blood circulation and prevent the formation of pressure sores.

50% alcohol can be used to reduce fever physically. Patients with high fever can use it to wipe their bodies to achieve the purpose of cooling down. Because wiping with alcohol can dilate the patient's blood vessels, increase the heat dissipation capacity, and its volatility can also absorb and take away a large amount of heat, so that the symptoms can be relieved.
