Recycled Spherical Silica Powder

1/

返回中文介面:再生球形二氧化矽粉
Conventional silica is generally produced through high-temperature, energy-intensive processes such as melting, making it a material associated with high carbon emissions. Semiconductor packaging processes in Taiwan generate approximately 3,000 tonnes of waste epoxy moulding-compound offcuts each year. This waste consists of more than 80% silica, together with thermosetting resin, and was previously disposed of mainly through incineration. Recycled spherical silica is recovered using waste moulding-compound pyrolysis and resin-removal technology. The discarded packaging material undergoes crushing, decarbonisation and purification, washing, magnetic separation, acid washing, drying and particle-size classification. The recovered powder has a purity exceeding 90%. The material has obtained Product Carbon Footprint (PCF), Global Recycled Standard (GRS) and Green Mark certification. The recovered spherical silica can be used in floor-coating systems to improve the compressive strength and abrasion resistance of the coating while reducing resin consumption. It can also be combined with EVA to produce slippers, reducing the amount of plastic raw material required. Compared with conventional EVA raw materials, this application can reduce carbon emissions by approximately 61%, demonstrating a high-value use for semiconductor waste. more
