The application of obpa in ship paint extends the service life
10,10 '-oxyphenopyrite is mainly used as a fungicide in ship paint, and its application has the following characteristics and advantages:
1. Anti-mold and antibacterial performance
OBPA is an efficient industrial fungicide that can simultaneously prevent mold, fight bacteria and resist algae. It is one of the most effective antibacterial agents in the industrial field. Adding OBPA to ship paint can effectively inhibit the growth of mold, bacteria and algae, prevent the ship paint from deteriorating and getting moldy due to microbial contamination, and thus extend the service life of the ship paint.
Ii. Chemical Stability and Weather Resistance
OBPA has good chemical stability, does not hydrolyze, and is stable under weak acid and weak base conditions. It can also prevent the development of microorganisms for a long time, has a long-lasting medicinal effect, and is resistant to rain erosion. For instance, the sterilization effect of polyvinyl chloride thin plates mixed with 0.05% OBPA remains unchanged after continuous 24 hours of water washing or 100 hours of sun and rain treatment.
OBPA has excellent weather resistance and heat resistance. It does not decompose at temperatures below 300℃ and is suitable for use in Marine coatings that need to be exposed to harsh environments for a long time.
Iii. Dosage and Usage Method
The addition amount of OBPA in Marine paint is generally 0.05% to 0.2%. The specific addition amount needs to be determined based on the formula of the Marine paint and the usage environment.
OBPA can be added during the production process of ship paint or when formulating coatings. When adding, it is necessary to ensure thorough and uniform stirring to guarantee the uniformity of its anti-mold and antibacterial effects.
Iv. Safety and Environmental Protection
Although OBPA contains arsenic, which has a certain irritating effect on the skin, eyes and gastrointestinal tract, in practical use, due to its extremely low dosage (for example, when used in plastics, the arsenic content is about 90 to 150PPm), which is close to the arsenic content in some foods, its safety is relatively high.
The application of OBPA in ship paint complies with environmental protection requirements and will not cause significant pollution to the environment.
