Antibacterial Purification Wall Board

The surface of the Antibacterial Purification Wall Board integrates inorganic antibacterial materials, creating a smooth, dense, and seamless finish free of micro-pores or crevices; it prevents the accumulation of dust and dirt and inhibits microbial retention, combining dust-proof, hygienic, and antibacterial protective systems.

It is suitable for environments requiring high standards of hygiene and cleanliness, such as biological laboratories, sterile pharmaceutical facilities, and medical aesthetic surgery suites.

What is Antibacterial Purification Wall Board?

Antibacterial purification wall board is an upgraded panel that adds antibacterial function to ordinary purification boards. It typically incorporates inorganic antibacterial agents into the surface coating or adds an antibacterial film between the steel plate and core material.

Its function is: even if bacteria land on the panel surface, they cannot survive and reproduce on the surface for extended periods.

Our boards are suitable for places with additional requirements for microbial control — not all purification projects need antibacterial boards, but in specific scenarios, they are an essential configuration.

Antibacterial Technology Principle & Testing

The antibacterial principle of antibacterial purification wall panels incorporates inorganic antibacterial agents such as silver ions or zinc ions into the coating, functioning through a contact-type bactericidal mechanism.

When bacteria contact the panel surface, the metal ions released by the antibacterial agent destroy the bacterial cell membrane, inhibiting their reproduction and survival.

Testing standard refers to GB/T 21866-2008, with antibacterial rate ≥ 99% recognized as qualified antibacterial products.

Precautions during use:

- Regular cleaning removes surface organic dirt, maintaining the contact effectiveness of antibacterial agents.

- Avoid using strong acid cleaners to prevent damage to the loading stability of antibacterial components in the coating.

- Under normal use and cleaning conditions, inorganic antibacterial agents do not significantly attenuate due to wiping or the passage of time.

Core Advantages

1. Broad-Spectrum Antibacterial: Inhibitory effect on both Gram-negative bacteria (E. coli) and Gram-positive bacteria (Staphylococcus aureus), with antibacterial rate ≥ 99%.

2. Long-Lasting Antibacterial Efficacy: Inorganic antibacterial agents do not volatilize or leach out, curing together with the coating on the steel plate surface. Efficacy lasts as long as the coating itself, without attenuating over time like organic antibacterial agents.

3. No Change to Substrate Properties: Adding antibacterial agents does not affect the mechanical properties, processing performance or welding performance of the steel plate. Cutting, bending, punching and other processes are exactly the same as ordinary panels.

4. HACCP Audit Support: For food production enterprises, using Antibacterial Purification Wall Boards helps pass the environmental microbial control review items in HACCP system audits.

FAQ

Q1: Can Antibacterial Purification Wall Boards replace daily disinfection?

A1: No. The function of antibacterial boards is to inhibit bacterial reproduction on the panel surface, but it cannot replace daily disinfection procedures. Organic dirt on the panel surface still needs to be removed according to standard cleaning procedures. Antibacterial boards are a supplement to wall protection, not a replacement.

Q2: Will the antibacterial effect decline after long-term use?

A2: Inorganic antibacterial agents are not depleted by wiping. However, if the panel coating is damaged by external scratching, the antibacterial function in the damaged area will be lost. Therefore, maintaining intact coating under normal use conditions is key.

Q3: Are there color options for the board surface?

A3: Yes. Regular RAL color chart colors can be produced. The antibacterial coating itself is colorless or light-colored, without affecting color matching.

After-Sales Service Instructions

Antibacterial purification wall panels are delivered with an antibacterial performance test report (issued by a third-party laboratory, with test date corresponding to production batch).

In addition to the standard 12-month warranty, the after-sales service provides an additional 6-month quality commitment for antibacterial performance — if the antibacterial rate drops below 90% (tested according to GB/T 21866-2008) within 18 months from delivery, the corresponding panels will be replaced free of charge.
