苏州地区社队石棉厂分布于吴县、吴江、昆山、沙洲、无锡等地,设备陈旧简陋,以手工原始生产为主,部分厂虽有少量机械,但防尘措施不良,灰尘飞扬,劳动条件十分恶劣,因此,石棉肺发病较高。社队企业石棉加工,石棉尘虽然严重,但只要有合理的有效防尘措施,加强管理,控制粉尘危害还是能够做到的。工艺改革:碾磨加料,可用隔室加料,轮碾密闭加吸风,加料口有一定的控制风速1m/s以上,使操作工呼吸带粉尘由原来的84.4mg/m~3下降到2.12mg/m~3。密闭操作①弹花防尘:弹花机宜用大密闭室隔室加料、加料口控制风速1m/s左右,粉尘浓度由24.47mg/m~3下降到2.19mg/m~3。②纺线、拼线防尘:纺拼线原来使用“黄道
Asbestos factories and teams in Suzhou are distributed in Wuxian, Wujiang, Kunshan, Shazhou, Wuxi and other places. The equipment is old and crude, with the original production by hand. Although some plants have a small amount of machinery, the dust-proof measures are not good and dusty and the working conditions are very high Harsh, therefore, asbestos lung disease is higher. Asbestos processing company community, asbestos dust, although serious, but as long as there is a reasonable and effective dust control measures to strengthen management and control of dust hazards or can be done. Process reform: grinding feed, available compartment feeding, wheel grind closed plus suction, feeding port has a certain control of wind speed above 1m / s, so that the operator breathing belt dust from the original 84.4mg / m ~ 3 down to 2.12mg / m ~ 3. Closure operation ① bombs dust: the bomb machine should use airtight chamber compartment feeding, feed port control wind speed of about 1m / s, dust concentration decreased from 24.47mg / m ~ 3 to 2.19mg / m ~ 3. ② spinning, dustbin dust: Spinning original use of the "ecliptic
