Zhejiang and Haier’s Eco-Friendly Deplasticizer Speeds Up Manufacturing

In the bustling world of manufacturing, where efficiency and innovation are the lifeblood of progress, a groundbreaking development has emerged from the labs of Zhejiang Wuyuan Technology Co., Ltd. and Qingdao Haier Smart Kitchen Appliances Co., Ltd. A team of researchers, led by LU Guojian, has developed a highly efficient online deplasticizer designed to revolutionize the process of removing plastic coatings from accompanying hangers. This innovation, published in the journal ‘Cailiao Baohu’ (translated as ‘Materials Protection’), promises to significantly impact the energy sector and beyond.

Accompanying hangers, those small yet crucial components used in various manufacturing processes, often come with plastic coatings that need to be removed before they can be reused or repurposed. Traditionally, this deplasticization process has been time-consuming and environmentally taxing. However, the new deplasticizer, composed of benzyl alcohol, benzaldehyde, ethylene glycol, ethers, and organic and inorganic bases, is set to change the game.

The research, conducted under ultrasonic conditions with a frequency of 40 kHz, revealed that the deplasticizer can completely remove a plastic powder coating of 60-70 micrometers in thickness in less than three minutes. This remarkable efficiency is achieved at a temperature range of 60-75°C and a promoter concentration of 2.1-3.3 g/L. “The key to our success lies in the careful selection and combination of solvents and promoters,” explained LU Guojian, the lead author of the study. “This formulation ensures low volatility and minimal corrosiveness to sheet metal, making it both safe and effective.”

One of the standout features of this deplasticizer is its recyclability and regenerability. This not only reduces waste but also lowers operational costs, a significant advantage for industries looking to optimize their processes. The deplasticizer works by disassembling the polymer network structure of the plastic coating, dispersing or dissolving it layer by layer until the coating is completely removed. This method is not only efficient but also environmentally friendly, aligning with the growing demand for sustainable manufacturing practices.

The implications of this research are far-reaching. In the energy sector, where efficiency and cost-effectiveness are paramount, the ability to quickly and safely remove plastic coatings from components can lead to significant savings and reduced downtime. This innovation could also pave the way for similar advancements in other industries, such as automotive and aerospace, where the removal of protective coatings is a common challenge.

As the world continues to push towards more sustainable and efficient manufacturing processes, innovations like this deplasticizer are crucial. They represent a step forward in our ability to balance productivity with environmental responsibility. The research published in ‘Cailiao Baohu’ (Materials Protection) is a testament to the potential of collaborative efforts between academia and industry, and it sets a new benchmark for what is possible in the field of materials science and engineering.

The future of manufacturing is bright, and with developments like this, we can look forward to a more efficient, sustainable, and innovative industrial landscape. As LU Guojian and his team continue to refine and expand their work, the impact of their research is likely to be felt across multiple sectors, driving progress and setting new standards for excellence.
