(Summary description)The cleaning at clean room is a very important daily work for a pharmaceutical enterprise. The level of cleaning cloth, as the main tool for cleaning work, will directly affect the efficiency and result of such works. But we find many pharmaceutical enterprises are still not clear about how to select this tool. We give some standards regarding the quality of cleaning cloths hereinafter for your reference and communication:
1.For the total particle quantity in liquid environment (the adaptation of cleaning cloths in a cleaning environment can be determined by simulating and testing the total quantity of particles which the cleaning cloths are generated in liquid environment during the actual usage process), generally the quantity of particles ≥0.5μm or ≥5μm will be calculated. The unit is in million particles/m2. The less quantity of particles means the better performance of cleaning cloths.
2.For the total quantity of no-load particles (measuring the quantity of no-load particles which are released from cleaning cloths (or other materials) when they are under stress or similar stress under a dry state during actual usage process), generally the quantity of particles ≥0.5μm will be calculated (unit: Particles/m2/ft3).
3.The quantity of fiber released is the total load quantity of fiber after measuring a certain stress which cleaning cloths bear in a liquid environment (by simulating the actual usage). Generally the total quantity of fiber ＞100 micron is calculated (unit: fibers/m2).
4.The test of non-volatile residues
5.Adsorption capacity (adsorption speed and amount, the quicker the adsorption speed is, the better the performance of adsorption amount will be)
6.Content of metal ion
The clean room is a core zone for pharmaceutical production. All incoming materials will be strictly controlled according to relevant conditions. But most of enterprises at present, including parts of experts, think all non-woven fabrics can satisfy the demand of clean room, which is a very big mistake.
The non-woven fabric is just a joint name. The environment for manufacturing enterprises of cleaning cloths is different. Most of them are produced not in a strict clean environment. So the products themselves are pollution sources, and the cleaning work by them will get only half the result and bad result. Not to speak of the traditional method by use of self-made dust-free cloth towel, it is just to clean off the dirt you may see, while more tiny particles produced in this process would turn to be hidden danger affecting the quality of product.
