The 2026 China-Europe Pipeline Engineering and Trenchless Rehabilitation Technology Academic Conference grandly opened in Shenyang. As a technical pioneer in the trenchless rehabilitation field, Dongguan Ergu Optoelectronics Technology Co., Ltd. (hereinafter referred to as "Ergu Optoelectronics") was invited to attend. The company showcased its two core products—the UV Curing System and the Thermal Curing Air Pressure Inversion Drum—gaining significant industry attention.

On January 16, 2026, the Fourth Fourth Membership Conference and Technical Exchange Annual Meeting of the Guangdong Provincial Trenchless Technology Association was grandly held, attracting significant industry attention. As a key force in the trenchless field, Dongguan Ergu Optoelectronics Technology Co., Ltd. (hereinafter referred to as "Ergu Optoelectronics") was invited to attend this grand event.

Photocatalysis technology is an efficient and safe environmentally friendly environmental purification technology. When ultraviolet light with energy greater than or equal to the energy gap is irradiated onto semiconductor nanoparticles, electrons in their valence band will be excited to transition to the conduction band, leaving relatively stable holes in the valence band, thus forming electron hole pairs. Due to the presence of numerous defects and dangling bonds in nanomaterials, these defects and dangling bonds can capture electrons or holes and prevent their recombination.

There are several factors that affect the quality of UVLED light curing: 1. Characteristics of the cured material: The curing speed and effect of the UVLED curing machine are largely determined by the difficulty of ultraviolet light entering the cured material to induce light and trigger molecules.

The maintenance and upkeep methods of the curing machine are as follows: 1. Clean regularly. Clean the dust and debris inside the UVLED surface light source curing machine to ensure that the interior of the machine is clean and tidy. 2. Before each startup, check if the circuit board is working properly. If any problems are found, please contact professional personnel for repair in a timely manner. 3. Lubricate all moving parts in the machine to ensure smooth operation.
