In the post-epidemic era, the antibacterial performance of classroom desks has become a core concern for educational institutions. Faced with the two mainstream technologies of nanosilver coating and PET antibacterial coating on the market, how can purchasers strike a balance between cost, effect and durability?

一. Comparison of technical principles and antibacterial efficiency

1. Nanosilver coating: a long-term choice for chemical antibacterial

Mechanism of action: Silver ions are embedded into the desktop coating through nanotechnology to destroy bacterial cell membranes and inhibit DNA replication, achieving 99.9% broad-spectrum antibacterial.

Authoritative certification: Passed ISO 22196 standard, the antibacterial effect lasts for 5-8 years.

2. PET antibacterial coating: a cost-effective solution for physical protection

Mechanism of action: Cover the desktop with a PET film containing an inorganic antibacterial agent, kill surface microorganisms by contact, and the antibacterial rate is ≥99%.

Limitations: If the film layer is damaged, the local antibacterial performance will fail.

Comparison of measured data:

二. Cost and service life: Which one has more long-term value?

1. Initial purchase cost

Nanosilver coating: Due to the complexity of silver ion raw materials and spraying process, the unit price is 25%-30% higher than that of ordinary desks.

PET coating: The coating technology is mature and can be mass-produced, with a premium of 10%-15%.

2. Full-cycle use cost

Maintenance cost: Nanosilver coated desks only need to be cleaned with water on a daily basis; PET coating needs to avoid scratches from hard objects, and the average annual maintenance cost is 18% higher.

Replacement frequency: PET coating needs to be re-applied every 3-5 years on average; the life of nanosilver coating is the same as that of the main body of the desk.

Case calculation: An international school purchased 1,000 sets of desks. The total cost of the nanosilver solution was 15% higher than that of PET coating, but it saved more than 40% of maintenance costs within 10 years.

三. Applicable scenarios and purchasing suggestions

1. Give priority to nano-silver coating

Demand scenarios: public schools, laboratories and other places with high hygiene requirements that are frequently used;

Policy-driven: Comply with the EU Biocidal Products Regulation and the US EPA certification, suitable for the export market;

Brand case: AOYASI customized nano-silver coated desks for an education group in Singapore, and the surface antibacterial rate after 3 years of use is still 99.3%.

2. Economical solution for PET coating

Demand scenarios: small and medium-sized kindergartens with limited budgets, training centers for short-term use;

Quick response: AOYASI supports 15-day rapid delivery of PET coated desks to meet emergency procurement needs.

四. Technology integration and innovation: AOYASI's "double-effect antibacterial" solution

Base layer: Nano-silver coating provides long-term antibacterial effect;

Surface layer: Ultra-thin PET coating prevents coating wear, and photocatalyst ingredients are added to enhance the sterilization effect under light;

Measured data: Antibacterial durability is increased by 30%, and the overall cost is reduced by 12% compared with the pure nano-silver solution.

五. Industry Trends: Intelligent Antibacterial and Data Management

IoT Integration: Embed sensors in nano-silver coated desks to monitor the number of surface colonies in real time and issue warnings through APP;

Recycled material upgrade: Recycled silver ions and bio-based PET film are used to reduce the carbon footprint of antibacterial desks by 33%.
