Description
Technical field
The present invention relates to a kind of system and method for use in testing for the clothing system protection validity of using under the clean room environment.
Background technology
Toilet's pollution and control field ubiquity the phenomenon of a kind of heavy hardware (technology, equipment), light and soft (program and management) at home at present.The toilet that we are can building equipment quite advanced, cleanliness factor is very high, but these toilets have been after having passed through empty state, the test of static cleanliness factor, and its dynamic cleanliness factor is often from below standard.Clearly problem goes out the clothing system that uses in the toilet, and toilet's clothing system should play a protective role to the staff, and pollutant is not spread in the clean room environment.Understand from the angle of polluting, the people is regarded as pollutant maximum in the toilet source takes place, according to the Robin HowieAssociates (Edinburgh of company, Scotland) description of Robin Howie, the people can produce thousands of grit in toilet's activity, these particles comprise bacterium, mould and the saccharomycete that can breed, and the particle that can not breed, as hair, scurf and dandruff etc.If but select inappropriate clothing system (as loosely organized clothing system) for use, or use the clothes that clean repeatedly, wear and tear, dry and disinfect, As time goes on, the clothes of toilet also can slowly wear out, and do not have protective effect.But at present domestic also having no idea to the dynamic protection validity of toilet's clothing system (being the protection validity of staff's dressing clothing system when carrying out work); can use the toilet of which grade with definite this clothes, or judge whether this clothes can also use after cleaning repeatedly.
The clothing system that present domestic toilet uses substantially all is to reuse through cleaning the back.Clothes are through after cleaning repeatedly, wear and tear, dry and disinfecting, and structure can slowly wear out, and protection validity just reduces.Now often rule of thumb determine the replacing of clothes; there is not measured data; bring some may also play good protection validity like this and be replaced and cause waste, and some may look can manage it but in fact not only do not play a protective role may be also since loosely organized increase pollute.So be badly in need of the protection validity that a kind of detection method of science is judged toilet's clothing system.
At present the F-51 method (microscopic method) that mainly contains four kinds of method: ASTM detects to the purifying property of the clothing system that uses in the toilet in China, and F-51 repaiies demonstration (counting method), HELMKE rotating-cylinder method (drum process) and vibration test method (vibratory drilling method).
ASTM-F51 (U.S. material and experiment association (ASTM)) is the standard method that test toilet's garment material (one one square feet in size clothing is placed on the wire gauze) filtered particles is polluted size and quantity.ASTM-F-51 method (microscopic method): test probe is equipped with filtering diaphragm, directly connects the air draught volume pump, and the air capacity of passing through is 28L/min.Make air by testing dress material during test, grit of sending out that contains in the air is caught on the filter membrane of test usefulness, observe and statistics dust particle number with 400 power microscopes.Read 0.5-5 and 5 above particle numbers above the filter membrane.On filter membrane, be printed on the grid of 3.08mm, can read the population in the grid; ASTM-F-51 revises method (counting method): make air by testing dress material, measure size and the number of sending out grit with corpuscular counter.Sample is placed on the stand of band wire netting, attracts with the sampling thief contact, the air capacity of passing through is 28L/min.Though this test is simple, and is very consuming time, lack repeatability, and just test the particle strainability of garment material, be not suitable for the film clothes yet.
Drum method (Helmke Drum Test) is that the drum that clothes are put into the rotation of a lateral opening is rotated, and to sending out a grit sub sampling, measures particle number with corpuscular counter in the bucket.Helmke Drum method of testing can be used to assess 0.3 micron and larger sized particle.
Vibratory drilling method is that clothes are placed in the cell, reverses the generation particle by vibration, measures with corpuscular counter.Simultaneously, the particle big to particle diameter (more than the 25 μ m) traps on the filter membrane, reads particle number.
Though these two kinds of methods are in dynamically test down, but this motion state and staff have any different in toilet's active state, and the pollutant that these two kinds of methods are used is manually to send out dirt, also has any different with the pollutant of the actual generation of staff, therefore influences evaluation result.
So, the present invention is directed to the dynamic testing method that the problems referred to above propose a kind of cleaning room garment system protection validity, come the clothing system of toilet is judged, and and then determine serviceable life of this clothing system.
