Antibacterial agent for rubber sealing parts of valves, in compliance with EU standards
Highly efficient and broad-spectrum antibacterial property
The antibacterial and antifungal agents of Dalian Tianwei (such as silver ion and zinc ion series) have an inhibition rate of over 99% against common pathogenic bacteria like Escherichia coli, Staphylococcus aureus and Candida albicans, and can also inhibit the growth of molds such as Aspergillus Niger and Aspergillus flavus. This is crucial for the long-term use of valve rubber seals in damp environments, effectively preventing the decline in sealing performance or material corrosion caused by the growth of microorganisms.
High-temperature resistance and chemical stability
Its inorganic antibacterial agents (such as the zeolite silver-loaded system) can withstand a high temperature of 450℃, and they have stable chemical properties and are not prone to react with rubber substrates or other additives. During the processing of valve seals, high-temperature vulcanization is often required. The use of Dalian Tianwei antibacterial agent can ensure that the antibacterial effect is not affected and at the same time avoid the harmful substances produced by high-temperature decomposition.
Safety and environmental friendliness
The product has passed the EU RoHS Directive, SGS antibacterial test and ISO22196-2011 standard certification. It contains no heavy metals, halogens or carcinogens and meets the safety requirements of food contact grade. This is particularly important for the application of valve seals in fields such as drinking water and medicine.
Long-term effectiveness and durability
Through sustained-release technology, antibacterial agents can stably release active ingredients for a long time, with an antibacterial period of several years. Even if the surface of the seal is worn, the internal antibacterial agent can still continue to function, extending the service life of the product.
Ii. Technical Compatibility Analysis
Compatibility with rubber substrates
We offer powder and liquid antibacterial agents that can be flexibly added to various rubber materials such as natural rubber, silicone, and EPDM. It has a small particle size (1-2μm) and a large specific surface area (10-15m²/g), which can be uniformly dispersed in rubber without affecting the physical properties (such as hardness and elasticity) and processing technology (such as vulcanization speed) of the sealing parts.
Weather resistance and anti-aging property
Some products combine organic antibacterial agents with layered clay through intercalation technology, solving the problems of easy discoloration of inorganic antibacterial agents and poor weather resistance of organic antibacterial agents. Valve seals are often exposed outdoors or in harsh working conditions. Such antibacterial agents can ensure color stability and no decline in antibacterial performance over long-term use.
Customized solutions
Tianshi Blue Shield can adjust the particle size, release rate and addition ratio of antibacterial agents according to customer requirements. For instance, in the high-pressure and high-frequency friction scenarios of valve seals, the adhesion between antibacterial agents and rubber can be optimized to prevent the antibacterial layer from peeling off due to wear.
Iii. Application Cases and Industry Recognition
In the field of household appliances
Tianshi Blue Shield Antibacterial Agent has been widely used in the sealing strips of household appliances such as refrigerators and washing machines. According to actual tests, its antibacterial rate against common bacteria reaches 99.9%, significantly enhancing the hygiene level of the products. Valve seals and household appliance sealing strips are similar in material properties and working conditions, and their technologies can be directly transferred and applied.
Industrial field
In the valve seals of industries such as petroleum and chemical engineering, Tianshi Landun antibacterial agent extends the service life of the seals in corrosive media by inhibiting microbial corrosion (MIC). For instance, after a certain oilfield enterprise adopted its antibacterial seals, the maintenance cycle of the valves was extended from six months to two years.
International certification and export experience
The products comply with the safety standards of the Middle East, Europe, America, Southeast Asia and other regions, and have been exported to many countries. For valve enterprises with export demands, Tianshi Landun can provide antibacterial solutions that comply with the regulations of the target market.
