茶生肺【茶尘的来源】茶尘是茶叶加工过程中产生的一种对人体有害的粉尘,如筛选、轧切、凤选等,均有茶尘产生,由于茶叶固有的茸毛灰,即茶叶嫩芽期叶面上形似针状的茸毛和在加工过程中碎断而产生的细灰,以及茶叶夹带来的泥尘等。经对××茶厂车间空气中茶尘浓度测定结果,平均浓度为125mg/M~3(27—322mg/M~3),其分散度在5μ以下者为85％以上,其粉尘中游离SiO_2含量平均为8.7％
Tea Pulp Health Source of Tea Pulp Tea dust is a kind of dust which is harmful to human body during tea processing. For example, tea dust is generated due to screening, rolling, Tea buds on the surface of the shape of needle-shaped hair and broken in the processing of fine ash, as well as the entrainment of tea dust and so on. The results showed that the average concentration of tea dust in the air of workshop of ×× tea factory was 125mg / M ~ 3 (27-322mg / M ~ 3), the dispersity was above 85%, the content of free SiO_2 The average content of 8.7%
