Professor Wang Jiadao, director of the Institute of Surface Interface Micro-nano Technology and professor of Tsinghua University's Department of Machinery, and his team, based on the basic theoretical research on fluid-solid interface effect control, have proposed new technologies such as self-assembly micro-nano manufacturing, interface effect drag reduction, surface self-cleaning, and precise cell control. Tianjin Qingke Environmental Protection Technology Co., Ltd., a product industrialization company, has hatched a variety of innovative products in the fields of air purification, water treatment, disinfection and sterilization.

In research related technology and application

Self-cleaning coating technology
The use of low surface energy coating, so that the surface of the object with non-stick, can be used for solar cells, building materials, clothing and other waterproof self-cleaning.

     

 

Oil-water separation technology based on super-affinity/super-hydrophobic
The micro-nano composite self-assembly coating forms a super-hydrophobic, super-lipophilic or super-hydrophilic, super-oleophobic surface, which is applied to the treatment of various oily wastewater such as lubricating oil, emulsion, oil field produced water and so on.

      

Cutting fluid wastewater treatment system

 

Adsorption/catalytic nano-coating purification technology
Through the self-assembly of modified catalyst materials and porous materials, the efficient adsorption and catalytic decomposition of indoor harmful gas molecules such as formaldehyde have been realized, and a series of products such as aldehyde deodorization and color-changing balls have been formed.

S-RCD chlorine dioxide slow release technology
Positive modified porous nanoparticles and negative hydrogel self-assembly to achieve gaseous slow-release chlorine dioxide. Used in disinfection, sterilization, in addition to aldehyde, in addition to taste, preservation.

nano needle transfection technology
Using self-assembly technology to manufacture micro-nano needles, combined with micro-flow-MEMS vibration system, to achieve high-throughput and high-efficiency mechanical mechanism cell transfection.

 

surface drag reduction technology
By means of microstructure coating or film, the surface drag reduction is realized, which is used for sports racing projects to reduce the surface drag of equipment, such as indoor bicycles, kayaks, helmets, skis, etc.

 

Waste water and waste gas treatment technology
Waste gas: the use of spray, catalytic, RCO, RTO and other technologies to achieve odor gas, paint waste gas, nitrogen oxides, VOCs and other pollution gas treatment;
Wastewater: metal chelation, electrocatalysis, nano bubble technology to achieve heavy metal wastewater, machining wastewater, cutting fluid, electroplating wastewater treatment.
