In order to effectively control and reduce the impact of harmful anti-fouling systems on ships on the marine environment, the International Maritime Organization IMO formally adopted the International Convention on the Control of Harmful Anti-Fouling Systems on Ships (hereinafter referred to as the "AFS Convention") in October 2001, and It came into effect on September 17, 2008. The "AFS Convention" officially entered into force for my country on June 7, 2011. For details, please refer to the Ministry of Transport Announcement No. 22 of 2011: Announcement on the Entry into Force of the International Convention on the Control of Harmful Anti-Fouling Systems on Ships of the International Maritime Organization).

Antibacterial and antiseptic is a new type of environment-friendly broad-spectrum antiseptic, especially suitable for high temperature environment and alkaline system. It is 1-2 benzisothiazolin-3-one (BIT). It is a new generation of important environmentally friendly industrial fungicides and preservatives.

What is sterilization (sterilazation, sterilant)? Refers to the process of using strong physical and chemical factors to kill or remove all pathogenic and non-pathogenic microorganisms in the external environment, including bacterial spores and fungal spores. It is an absolute concept. The effect is expressed by the sterilization rate, generally ≥99.9999%.

The antifungal agent has a strong inhibitory and killing effect on bacteria, fungi and algae. It is mainly suitable for daily use of antiseptic and mildew, such as cosmetics, detergents, gels, creams, liquid soaps and wet tissues. Anti-mold, usually refers to the dry film state of paint and other products, that is, the film, in order to prevent the growth of mold, an anti-mold effect is required. The anti-mold agent is in the dry film state, mainly targeting mold, killing and inhibiting the growth of mold An additive.

3Q-501 is a safe, high-efficiency, broad-spectrum antibacterial and anti-fungal agent. It has a white powder and is suitable for antibacterial and anti-mildew of plastics, rubber, leather, silica gel, etc. It is also suitable for EVA foaming process.

Product deterioration, odor, and thinning are problems caused by unfavorable anti-corrosion links. The following are cause analysis and production control measures:

The test of antibacterial properties of textiles is divided into quantitative test methods and qualitative test methods, and quantitative test methods are the most important.

Cloths and textiles are prone to mildew, mild weather, frequent rains and humid air seasons. It is most suitable for the propagation and growth of various bacteria, and the clothing is easy to mold. The surface structure of the cloth is loose, and it is easy to inhale the moisture in the air. The paint is a cotton material with strong moisture absorption capacity. It just happens that cellulose is what molds like to eat, so it is easier to grow mold. For this situation, the anti-mold agent is right The mold on the clothes has super resistance ability.
