the composite recycling center of Rogers Aluminum Co., Ltd. in the United States has achieved sustainable development within the life cycle. Recently, it successfully developed a new recycling technology of phenolic FRP

edge waste materials, and also improved the performance of recycled products

according to reports, the molding materials division in Connecticut, the United States, uses special recycling technology to treat the edge waste of phenolic FRP step by step, so as to obtain recycled materials with satisfactory performance. Researchers first grind the FRP edge waste into fine powder, and then add it to the new phenolic raw material according to a certain proportion (about 4 ~ 15%, in which the glass fiber content is about 50%), so as to obtain an ideal phenolic regenerative molding material. And

it is found that the finer the powder, the better the sealing performance of the products, and the more obvious the effect of improving the performance

according to China's epoxy resin industry (), the company has adopted this method of adding recycled powder on a pilot production line and has been put into the production process of batch products. The proportion of recycled powder

used is about 10%, and the glass fiber content in the new phenolic raw material is about 40%. According to the measured results of product samples,

the tensile strength can be increased from 8279psi to 9265psi at 302 ° f; The bending strength is strictly accountable to the relevant responsible person from 17660ps, i

to 18995psi. Special engineering plastics will be a highlight of the meeting. According to the company, this recycled powder material of phenolic resin can also be used as aggregate in molding mixtures

The American asphalt research center has made a full technical and economic evaluation of the use value of this recycled phenolic powder, and believes that the performance of these powders is similar to that of the currently used fillers, but the performance of the products made of these mixtures has been significantly improved
