酚醛树脂玻璃钢是聚酯玻璃钢的一种,已广泛用于军工和民间。它是由酚醛树脂和玻璃纤维经热压成型的加筋混合体。切削、打磨、钻孔和抛光成型铸件可产生粉尘。该粉尘在显微镜下可见棕黄色的酚醛树脂颗粒和长短不等的直径7—8微米的玻璃纤维。国内外对吸入玻璃纤维及其粉尘对肺脏的影响进行了大量研究,但目前尚无一致结论。酚醛树脂在热解中能释放出有害蒸
Phenolic resin fiberglass is a polyester fiberglass, has been widely used in military and civil. It is made of phenolic resin and glass fiber by hot forming reinforced mixture. Cutting, grinding, drilling and polishing castings can generate dust. The dust under the microscope can be seen brown-yellow phenolic resin particles and the length of 7-8 microns in diameter glass fiber. A great deal of research has been done at home and abroad on the effects of inhaled fiberglass and its dust on the lungs, but there is no conclusive conclusion yet. Phenolic resins can release harmful steam during pyrolysis
