[问] 我厂主要是铸造暖气器材,在作锅炉片时,直到现在总是抖铅粉,弄的工人满身漆黑,可是工人不在意,因为要做到表面光洁,满足人民的需要。做暖气片时,同样都要在每个砂型上抖铅粉,比做锅炉片更弄的满天飞扬,发给口罩不能带,工人都吸到肺里去了。是否可以用其他材料代替,使铸件表面又能光洁,又能保障工人身体的健康。 [Q] Our factory mainly casts heating equipment. When making a boiler plate, until now, it always shudders with lead powder, and the workers are covered in darkness. However, the workers do not mind because the surface is smooth and the needs of the people are met. Do radiator, the same should be in each sand on the shake of lead powder, boiler plate more than make full of flying, the mask can not be sent to the workers to the lungs to go. Whether it can be replaced with other materials, the casting surface can be smooth, but also protect the health of workers.
