Woodworker cutting parameter is right all round the influence of air dust conten
From;  Author:Stand originally
The basis overcomes collect ground law, oak and beech lumber but the mass concentration limitation of inspiratory dust is 1 Mg/m3, limitation of total dust concentration is 3 Mg/m3. In research, studied two carpentry company, all round the woodworker in furniture and carpentry factory airy dust content. In weekday, use secure the sample chamber on worker dress to be opposite all round in air but inspiratory dust and total dust undertake sampling, decide a worker truly thereby the dosage of daily contact dust. Metrical mass concentration exceeded Keluodeya to restrict a cost: Be in furniture factory, but inspiratory dust is occupied 16% , total dust is occupied 18% ; And be in carpentry factory, but inspiratory dust is occupied 38% , total dust is occupied 65% . Be in furniture factory, but the mass concentration of inspiratory grain is standing by belt sander to be in want part of prep above fretsaw. In the workshop that sets these woodworker, but the mass concentration of inspiratory dust and total dust wants the air all round machinery of prep above other, for example milling machine of odd axis vertical, band saw and line dig. Be in carpentry factory, stand by fretsaw around but apparent prep above stands by inspiratory grain mass concentration the mass concentration of line dig or machine of chip engrave mill. It is all round the machine with the workshop with total low dust concentration and generation hub the smallest ply, but the share that inspiratory dust holds total dust is the largest.
