2009/3/27
The application of washable filters for particulate respirators in shipyards is reported; the problems concerning maintenance and care of the filters are discussed in consideration of filter features.
For the same horse power of the marine desiel, to minimize
the hull weight is the key factor in order to raise the steel
ship speed. At present, thin high and higher tensile steel
plates are widel...
