Polysilazane technology innovation: Precise molecular regulation unlocks new catalytic scenarios, and microfluidic applications break through
1. Breakthrough in water treatment: Heavy metal retention rate exceeds 99%
Ceramic membranes formed by high-temperature pyrolysis of polysilazane have achieved significant applications in the field of water treatment. The average pore size of this membrane is only 12nm, which can efficiently retain heavy metal ions such as Pb²⁺ and Cr⁶⁺ as well as bacteria and viruses in wastewater, with a retention rate of over 99%. It can withstand steam disinfection above 800℃, and its flux recovery rate is close to 100%. Its service life is more than three times longer than that of traditional polymer membranes. At present, it has been piloted in the deep purification project of industrial wastewater, and the treated water quality can be directly reused.
2. Air purification: The particulate matter in high-temperature exhaust gas is reduced to below 5mg/m³
For industrial flue gas treatment, polysilazane ceramic membranes loaded with catalytic components have performed outstandingly. Through the synergistic effect of surface charge adsorption and microporous sieving, it can not only capture 99% of PM₂.₅ particles, but also convert harmful gases such as SO₂ and NO youdaoplaceholder0 into harmless salts. In the tests of the petrochemical and steel industries, the concentration of particulate matter in the high-temperature exhaust gas filtered by this membrane was reduced to below 5mg/m³, far exceeding the ultra-low emission standards.
3. Green process: VOCs emissions are reduced by 70%
Environmental protection innovations at the production end are advancing simultaneously. The new water-based sol-gel method has replaced the traditional organic solvent system, reducing VOCs emissions during the production process of polysilazane by 70%. By simultaneously using bio-based methanol raw materials and combining them with clean production technologies, the annual carbon dioxide emissions can be reduced by 10%. This process has been certified by the EU REACH regulation, and the proportion of environmentally friendly products has jumped from 5% in 2020 to 12% in 2023.
4. New Applications in automobiles: Voltage-resistant coatings safeguard the safety of new energy vehicles
In the field of new energy vehicles, polysilazane derived materials have addressed the key pain points of battery safety. The voltage-resistant coating made from it has an insulation strength of over 10kV/mm and can withstand more than 50 cold and hot cycles from -40 ℃ to 500℃, effectively reducing the risk of battery short circuit. At the same time, when used as a tire adhesive, it can increase the bonding strength between rubber and reinforcing materials by 25%, thereby extending the service life of tires.
