Surface characteristic

Smooth surface: Purified aluminum profiles usually have a smooth surface. This smooth surface makes it difficult to attach because of the lack of microscopic structures that can hide and attach on smooth surfaces. For example, through high-precision extrusion and surface treatment processes, the surface roughness of profiles is reduced to a very low level, and the Ra value (contour arithmetic mean deviation) may reach below 0.8μm. Compared to rough surfaces, such smooth surfaces have fewer attachment points, reducing the possibility of breeding.

Non-porous structure: the material has a dense structure and no pores. This feature prevents liquids (such as water droplets contained within) from seeping into the interior of the profile, thus avoiding internal growth and outward propagation. Because if the material has pores, the liquid is easy to enter and remain in it, providing a breeding ground, and can spread with the flow or volatilization of the liquid.

coating

Additive coating: Some purified aluminum profiles are coated with an agent containing coating on the surface. These agents may be agents (such as quaternary ammonium compounds) or inorganic agents (such as silver ionizers). Taking silver ionizers as an example, silver ions can interact with cell walls or membranes, disrupting normal physiological functions and inhibiting growth and reproduction. When exposed to a coating containing silver ions, the silver ions penetrate the cell wall, bind to enzymes within the cell, and inactivate the enzyme, resulting in death.

Photocatalytic coating: Some purified aluminum profiles are coated with a photocatalytic material, such as titanium dioxide (TiO?) coating. Under light conditions, especially ultraviolet irradiation, titanium dioxide will produce strong oxidizing free radicals (such as hydroxyl radicals · OH). These free radicals are able to attack the cell wall, membrane and interior of the cell and will break down into harmless substances such as carbon dioxide and water. This photocatalytic coating is long-lasting and environmentally friendly, and can continue to work as long as there is appropriate light.

Easy to clean

Good chemical stability: The purified aluminum profile has good tolerance to common cleaners, which makes it possible to use a variety of agents for thorough cleaning during the cleaning process. For example, it can withstand the wipe of alcohol, hydrogen peroxide and other agents, and will not be corroded or damaged by these chemicals. When cleaning, these agents can effectively kill the adhesion to the surface of the profile, and because the profile surface is smooth, the agent can evenly cover the surface, further improving the cleaning.

Simple structure, no dead corners: the design of purified aluminum profiles usually takes into account the convenience of cleaning, and its shape structure is relatively simple, without complex shapes and difficult to reach dead corners. This makes it easy to wipe and clean the entire profile surface during the cleaning process, avoiding breeding and spreading in places that are not clean
