2 Cycle Power Generation Technology of Nanjing TICA Energy Technology Co., Ltd.

The cycle power generation technology displayed by Nanjing TICA Energy Technology Co., Ltd. adopts the principle of Organic Rankine Cycle, which is safe, stable and efficient. Organic Rankine Cycle (ORC) power generation utilizes the low boiling point of organic working medium. Generally, under the condition of medium and low temperature (90-300°C) heat source, the potential energy of working medium generated by the temperature difference between cold and hot sources is used to drive the expander to generate electricity, so as to convert low grade thermal energy into high grade electric energy. TICA has developed a series of power generation systems based on this technical principle, among which TICA's new generation PureCycle series Organic Rankine cycle (ORC) power generation system is representative.

The system can be configured in a dual-unit or multi-unit combination according to the user's needs, realizing full coverage below 3MW. High-efficiency expanders are used to realize heat and electricity conversion efficiency of 10%-20%. When there is sufficient heat source, multiple units can be connected in parallel to increase the power generation of the system, so as to make full use of heat while saving site space. It has a high degree of automation and can realize remote control. The system recovers medium and low temperature waste heat (80-300°C) for power generation, which can improve energy utilization efficiency and promote energy conservation and emission reduction.

Shandong Chambroad Timber Eco-friendly Wood

Chambroad Timber believes that wood is alive, and its internal fibrous cells exchange moisture with the outside world at all times. The resulting dryness, wetness, shrinkage and expansion often lead to frequent deformation, cracking and other problems of wood. In view of this pain point, Chambroad Gentlemen Wood extracts soluble sugar and inorganic salt from wood through high-tech pretreatment technology, and uses high-tech biomass modification technology to fill and modify the cell wall, which greatly overcomes the problems of original solid wood such as swelling deformation when exposed to water, warping due to water loss, cracking after long-term use, worm damage and corrosion, and overturns the disadvantages of traditional antiseptic process of only surface coating.

The product is characterized by controllable density and superior performance. Its maximum density can reach 1.2 g/cm³, elastic modulus up to 19380 MPa, water absorption expansion rate as low as 1.2%, and service life more than 10 times that of other outdoor materials. It has high performance index of Grade IX anti-termite, Grade I strong corrosion resistance, Grade B1 flame retardant, Grade 0 anti-mildew, and Grade ENf formaldehyde emission.

Puhua Ecological Low-carbon Functional Coating

As introduced, one of the fundamental reasons why ecological livable construction cannot be realized for several years lies in that latex paint itself is a pollution source. It releases harmful gases such as formaldehyde and VOC, which pollute indoor air and endanger human health. After years of research and development of ecological inorganic coatings, Puhua has overcome the microporous anti-blocking process of raw materials, broken the traditional "plastic film" wall surface, created a "breathable living wall", and realized long-term decomposition of harmful gases such as formaldehyde and VOC, thus providing people with a healthy indoor ecology. According to authoritative test data, compared with premium latex paint, Puhua's natural coating reduces carbon dioxide emissions by 54.74% per ton in the process of raw material selection and production.

Puhua's natural functional coating is featured by eight major functions: formaldehyde removal, sterilization, humidity control, mildew prevention, noise reduction, heat insulation, fire prevention and air purification, which can improve indoor air quality and create a healthy ecological environment. In 2016, it was certified as a green building product by the Singapore Green Building Council (SGBC).

The coating has a good pore structure, with a large number of micropores and active adsorption points. It can not only adjust indoor humidity by adsorbing excessive moisture in its pore structure, but also physically adsorb formaldehyde molecules in the pores of the coating through Van der Waals force and electrostatic force to reduce the concentration of formaldehyde in the air. The nanometer titanium dioxide (TiO₂) photocatalysis is used to carry out oxidation-reduction reaction with organic matters such as formaldehyde adsorbed in the pores, thus effectively decomposing harmful gases in the air and reducing the generation of secondary pollutants in indoor air. In addition, many functional materials such as silver ions, hollow beads, inorganic fibers, damping agents and infrared reflectors are added to Puhua's coating, which can not only well inhibit the growth of bacteria and mold, but also achieve energy-saving, heat insulation and noise reduction effects.

China Shenzhen Puhua Ecological Technology Co., Ltd.

Adhering to the development concept of "ecology, health, livability and low carbon", Puhua has successfully developed low-carbon ecological functional materials after more than 20 years of perseverance. Puhua's natural coating can not only help China achieve the "3060" dual carbon goals and save precious petroleum resources, but also fill the gap in technologies and materials for livable construction. It is a kind of world-first high-tech functional material.

The International Green and Low-carbon Technology Project Roadshow and Trade Conference is committed to playing a "bridge" role in actively promoting the combination of green and low-carbon technology and economic construction, and effectively building a technology display platform, multi-party cooperation bridge and green concept "exchange site" for technical parties and investors.
