Definitions

  • the present invention relates to a method for cleaning hard surfaces, especially in clean rooms, and devices for performing this method.
  • Clean rooms are to be understood in the following as rooms or parts of rooms in which an extraordinarily low level of heterogeneous air pollution, such as dust and germs, is to be present in the long term.
  • Such rooms are used to an increasing extent in medicine, for example as operating rooms, and in technology, for example for the production of pharmaceutical preparations or microelectronic components.
  • the extensive absence of dust, germs and other particles is achieved in these rooms by ventilation with only highly purified air.
  • the personnel who work in these rooms are subject to strict hygiene requirements and have to enter the rooms through special locks. Special standards are also set on furnishings, work materials and raw materials, for example in terms of dust content and abrasion resistance.
  • the invention relates to a method for cleaning hard surfaces, in particular in clean rooms, in which these surfaces are wiped using a cleaning liquid consisting exclusively of volatile components with the aid of a textile structure consisting of polypropylene continuous fiber fabric become.
  • This method is used particularly effectively on floors when the textile structure is in the form of a Mop cover is used together with a suitable mop holder.
  • a mop cover and a mop holder are therefore also objects of the present invention.
  • the new process enables extremely effective removal of particulate contaminants as well as oily and other adhering contaminants from the solid substrates. Fabrics (fluff) practically do not occur; Residues from the liquid cleaning agent are not to be feared.
  • the cleaning agent used in the process according to the invention is a liquid which consists exclusively of volatile components.
  • Components which evaporate completely from a thin layer at room temperature within minutes to a few hours are regarded as volatile. These primarily include substances that have boiling points below 100 ° C at normal pressure, in particular boiling points in the range between 50 ° C and 100 ° C.
  • organic solvents should be mentioned primarily, of which in turn the water-miscible organic solvents are particularly preferred.
  • Flammable organic solvents are normally not used alone but only in a mixture with water, the proportion of the water in this mixture generally predominating. In many cases the proportion of the organic solvent is not more than 15% by weight of the cleaning liquid, preferably it is between 1 and 10% by weight.
  • a mixture of demineralized water and monohydric alcohols with 2 to 4 carbon atoms is particularly preferred.
  • the cleaning liquid can contain other volatile additives, for example to increase the disinfectant effect or to increase the Cleaning power included.
  • additives are formaldehyde, ammonia, glycolic acid.
  • the textile structure which is used in the process according to the invention to distribute the cleaning liquid on the surfaces and to wipe the surfaces with it is a fabric which was produced from polypropylene continuous fibers, so-called filament yarns, or shaped Products that were made from such fabric. It was found in the context of the invention that fabrics made of polypropylene continuous fiber extraordinarily combine a high cleaning action with almost complete lint freedom. This applies particularly to polypropylene fabrics that were made from continuous fibers with an average fiber diameter of dtex 450 to 1,100. Fabrics with an average weight per unit area of 150 to 350 g / m 2 and structures made of such fabric are also particularly suitable.
  • the cleaning liquid is applied to the surface or to the textile structure made of continuous polypropylene fiber in an amount which depends primarily on the size of the surface to be treated but also on its nature and then with the textile structure spread over the surface.
  • the distribution of the cleaning liquid and the cleaning of the surface are achieved more or less simultaneously during the wiping on this surface.
  • the amount of cleaning fluid is between about 8 ml and 10 ml / m2. In the case of rough or porous surfaces, more cleaning liquid up to about 14 ml / m 2 may be necessary, while in the case of particularly liquid-repellent surfaces, significantly smaller amounts of cleaning liquid may also be sufficient.
  • the service life of the textile cleaning structure that the The method according to the invention which picks up dust particles, germs and other impurities naturally depends on the degree of soiling of the surfaces.
  • the textile structure is not rinsed or otherwise cleaned during use, but is optionally freed of the liquid absorbed by squeezing or wringing and replaced with a new textile structure after sufficient dirt absorption.
  • the surfaces can be wiped easily by hand, and simple cloths or, for example, glove-shaped structures can be used as textile structures.
  • the duration of the wiping treatment depends on the degree of soiling and in most cases is between about 3 seconds and 10 seconds per m 2 .
  • a holder in the form of a mop-like device. Suitable holders have been described several times for conventional floor cleaning, for example in German patent application 3432685 and in German utility model G 84 09 860.
  • holders are preferably used which have an elastic, abrasion-resistant support on their underside, for example made of closed have porous foam rubber.
  • modified mop holders in particular those which correspond in their other construction to German patent application 34 32 685, are therefore one own subject of the present invention.
  • the holders are generally designed in a foldable form, as is also described in the patent application cited above. The disclosure of this patent application is expressly made to the disclosure of the present application to the extent mentioned.
  • the textile structures suitable for alternating operation together with the holders mentioned have flat shapes and have two pockets on their surface for receiving the holder ends.
  • Mop covers of this shape which are made of polypropylene continuous fiber fabric, form a further subject of the invention. If appropriate, these covers can have further elements which are intended for fastening to the holder and are made from abrasion-resistant material. Examples of the form of such references can be found in German patent applications 3246161 and 3937 717, the disclosure of which is also made with the disclosure of the present application.
  • black PVC floor coverings were first cleaned thoroughly and freed of all dust. Overnight, these areas were exposed to the natural dust deposit of a room. In this state, pieces of 20 m 2 each of this floor covering were then sprinkled with a cleaning solution of 95% by weight distilled water and 5% by weight ethanol in an amount of 11 ml / m 2 . These surfaces were then wiped uniformly for 3 minutes using a mop consisting of a foldable holder according to German Offenlegungsschrift 3432685, which was provided on its underside with a wiping rubber covering and a matching cover.
