Method for processing high-polymer raw material cork particles

Abstract

The invention relates to a method for processing high-polymer raw material cork particles. The method comprises the steps that (1) firstly, collected cork is smashed through a cork smashing device into rough cork particles with the particle sizes being 10-15 mm; (2) the particle sizes of the rough cork particles obtained through smashing in the step (1) are further reduced through an accurate grinding device to enable the particle sizes to be uniform; (3) cork powder obtained through grinding in the step (2) is sequentially screened and classified through a multi-layer cork fine powder screening device according to the particle sizes; (4) impurities in the cork fine powder screened in the step (3) are removed through a cork powder winnowing collecting device, and finally, the cork fine powder are collected according to different particle sizes so as to obtain finished cork particle powder. The method has the advantages that the steps are simple, operation is convenient, the raw material utilization rate is high, the processing efficiency is high, meanwhile, and the cork particles obtained through the method are good in quality, low in output unit weight, low in water content and good in color and luster and are high-quality high-grade environment-friendly high-polymer biological raw materials with high physical and chemical stability.

Description

technical field [0001] The invention relates to a processing method of cork particles, in particular to a processing method of polymer raw material cork particles. Background technique [0002] Cork, scientific name cork oak or cork storage. Quercus cork, commonly known as oak, is mainly produced in the Qinba mountainous area of ​​my country, which is the largest cork producing area in the world. But all are wild forests, and the wild cork grows 1.5-3mm every year. Cork reserves are produced in the Mediterranean coast of Europe, mainly distributed in southern Portugal, Spain, France and other countries, mainly in Portugal, where artificial forestation is mainly used, and the annual growth of artificial forest cork can reach 3-5mm. Oak is one of the oldest existing tree species in the world, with a history of about 60 million years. It is also one of the oldest existing tree species in the world, and it is also the most precious renewable resource. Oak is a special tre...
