Восстановление растворителя: Активированный уголь в клеевых лентах

Activated carbon is widely used in the production of adhesive tapes.

The porous structure of activated carbon provides a multitude of adsorption surfaces, allowing it to exhibit outstanding adsorption capabilities. This enables efficient capturing and retention of solvent molecules, facilitating their effective recovery during the solvent recovery process.

На заводах по производству клейкой ленты основными восстанавливаемыми органическими веществами являются сами органические растворители, а также различные растворенные химические вещества. К ним относятся такие растворители, как толуол, ксилол, этан, ацетон и спирт.

After undergoing appropriate treatment and purification, the recovered organic substances can be reused in the production process. This not only reduces the need for new solvents, thereby lowering costs but also contributes to waste reduction and alleviating environmental impact.

In adhesive tape plants, activated carbon is usually used for solvent recovery in the following ways:

To capture and immobilize solvents effectively, a specialized adsorption system is utilized, which includes an activated carbon adsorber, associated piping, and equipment. 
As solvent vapors or exhaust gases pass through the adsorber, the activated carbon adsorbs and retains the solvent molecules on its surface and within its pores.
By controlling the flow rate and adsorption time, solvents are efficiently captured from the gas phase or vapor and immobilized on the activated carbon.

After passing through the adsorber, the gas stream or vapor containing the solvent is directed to a cooling system. This cooling system lowers the temperature, causing the solvent to undergo condensation and transform into a liquid state. This crucial step enables the separation and recovery of the solvent. The collected liquid solvent can then be efficiently collected and reused, promoting both environmental sustainability and cost-effectiveness in the process.

When activated carbon reaches its adsorption capacity and becomes saturated, its ability to adsorb solvent decreases. To continue utilizing the activated carbon, it needs to be regenerated. During regeneration, the activated carbon is subjected to either pyrolysis or steam treatment. By raising the temperature, the adsorbed solvent molecules are released from the activated carbon, effectively restoring its adsorption capacity. Once regenerated, the activated carbon can be reintroduced into the adsorber for the subsequent solvent recovery cycle.

The use of activated carbon for solvent recovery has many advantages, such as :

Solvent recovery using activated carbon reduces solvent consumption, leading to lower production costs. Properly treated and purified recovered solvents can be reused, promoting resource recycling and cost-effectiveness.

Solvent recovery significantly reduces environmental impact. By minimizing waste solvent emissions, it reduces pollutant release, disposal costs, and the demand for natural resources.
Enhanced Sustainability:

Solvent recovery improves the sustainability of adhesive tape plants. By maximizing solvent resource utilization, it reduces the need for new solvents, resulting in lower energy consumption, reduced carbon emissions, and a lighter environmental footprint.

Stringent regulations governing volatile organic compounds (VOCs) emissions exist in many regions. Activated carbon-based solvent recovery helps tape mills meet environmental regulations and comply with emission standards.

In adhesive tape factories, efficient solvent recovery is crucial, and Huamei Factory specializes in producing activated carbon specifically designed for this purpose. Our activated carbon enables the effective recovery of solvents like toluene and hexane.

While ordinary activated carbon on the market experiences a decline in effectiveness after three months of use, with a high breakage rate of 34% after one year, resulting in frequent replacements and increased costs, Huamei activated carbon stands out.

With Huamei activated carbon, its effectiveness remains consistent even after three months of use. The breakage rate is significantly lower, at only 7-8% after one year, allowing for extended usage for up to three years. This exceptional longevity translates to cost-effectiveness and minimizes the need for frequent replacements.

Choose Huamei activated carbon for your solvent recovery needs in adhesive tape plants, and experience its superior performance, extended lifespan, and cost savings.
