Definitions
- the invention relates to use of a system for maintenance of hard surfaces, primarily concrete (cement), terrazzo and granite floor surfaces, but also marble or limestone surfaces.
- the invention particularly relates to use of a tool for maintenance which is suitable for use on a daily basis to maintain a polished hard floor surface.
- the pad is usually provided as a circular, disc-shaped body, which is to be disconnectably mounted on a circular carrier plate, which in use is caused to rotate in a plane parallel with the floor surface, such that the pad, when brought into contact with the floor surface, is slightly compressed by the pressure arising between the floor surface and the carrier plate.
- the carrier plate is usually driven by a motor and may be mounted on a carrier frame, which may be arranged to be pushed or pulled by a walking operator or which may be arranged as a ridable vehicle.
- Such pads are formed from fibers of an organic material, e.g. polyamide and/or polyester, particularly polyethylene terephtalate.
- the fibers also include natural fibers, such as walnut fibers or coconut fibers.
- the fibers of the pad is interconnected at their mutual points of contact by so-called melt bonding, whereby the fibers are subjected to heat that cause the outer part of the fibers to slightly melt and thereby to bond to each other.
- the fibers may be interconnected at their mutual points of contact by the pad being impregnated with a polymer resin, hereinafter referred to as a "primary binder".
- US-A-3,537,121 discloses pads for polishing surfaces of aluminum, plastic, wax and similar surfaces. US-A-3,537,121 also discloses production of such pads.
- a binder mixed with abrasive particles is applied to the pad by passing the pad between a pair of squeeze rolls, one of which is partially immersed in a container for a mixture of binder resin and abrasive particles, after which the pad is allowed to cure or dry.
- a pad is provided, which is entirely impregnated by the binder and abrasive particles.
- US-A-4,893,439 discloses a pad for polishing floor surfaces or aluminum.
- the pad consists of fibers of organic material and constitutes a lofty open non-woven structure, and contains a binder binding abrasive particles to the fibers.
- the pad shown in US-A-4,893,493 has larger voids than that shown in US-A-3,537,121 , and thereby has an improved ability to absorb dirt, so that it can be used for a longer period. Also the pad disclosed in US-A-4,893,493 is entirely impregnated by binder and abrasive particles.
- EP-A-0 397 374 discloses a pad for floor polishing machines, which also is entirely impregnated by binder and abrasive particles.
- Pads of the above type are frequently used for so-called “burnishing”, i.e. dry polishing (often on a daily basis) of very lightly worn surfaces at high speed (1500-3000 rpm) and relatively low pressure, with a view to restoring a polished surface.
- This type of treatment is commonly used for both vinyl and marble floorings.
- Pads suitable for this purpose are available from 3M® under the designation “3MTM Floor Pads", and provide no or little effect on very hard floor surfaces, such as terrazzo or concrete, which have been subject to wear for a longer period of time.
- EP-B-0 562 919 discloses a non-woven pad of polymer fiber, which is entirely impregnated by a binder comprising a mixture of curable plastic resin and abrasive particles having a particle size of 0,1-30 ⁇ m.
- curable resins are mentioned phenol resin, acrylic resins, melamine resin and urea resin.
- Diamond is mentioned as one among several other examples of plausible abrasive particles.
- the pad disclosed therein is suitable for treatment of marble floor surfaces, and only in combination with crystallization chemicals, which means that treatment must be made in the presence of liquid containing a salt-forming acid.
- the pad in EP-B-0 562 919 is also provided by passing a non-woven pad through a nip between two squeeze rolls, one of which being partially immersed in a binder/abrasive particles mixture, such that the binder and abrasive particles, via the surface of the cylinder is distributed in the pad.
- the method described in EP-B-0 562 919 actually constitutes a vitrification method, used with a view to improving the stain resistance and durability of a marble floor.
- This method is not suitable for daily maintenance purposes, since it involves use of special crystallization chemicals, including acids, which are to react with calcium present in the floor surface to form insoluble calcium salts.
- Such a method is typically used once in connection with the initial preparation of the polished marble floor, and thereafter at intervals of 6-12 months.
- the method described in EP-B-0 562 919 is thus too complicated for being used on a daily basis.
- Pads of the type referred to in EP-B-0 562 919 are sold by 3M® under the designations "3MTM 5200 Brown Stone Renew Pad” and “3MTM 4000 Grey Stone Polish Pad", and are used for treating marble in the presence of crystallization chemicals and at relatively low speeds (below 250 rpm) .
- WO03/075734 discloses a disc-shaped device for cleaning purposes, comprising a nylon scouring material, which is arranged on a rigid disc, whereby grinding elements containing industrial diamonds are placed in recesses in the active scouring surface.
- a disadvantage with the device disclosed in WO03/07534 is that it does not eliminate the risk of debris getting stuck in or near the grinding elements.
- Yet another disadvantage is that this tool is complex and therefore more prone to breaking and more difficult and expensive to manufacture.
- the method should be simple to use, e.g. by persons who do not have specialist training in floor surface preparation, and the method should be usable with conventional floor surfacing equipment, e.g. burnishing machines, etc.
- the tools should be easy to manufacture, not too expensive and durable.
- the invention is based on the idea that abrasive particles in the form of diamond particles provide a polishing effect which is vastly superior to that achievable with those abrasive particles used in the examples shown in e.g. EP-B-0 562 919 , and that this polishing effect is so superior as to eliminate the need for crystallization chemicals.
- diamond is understood to include natural diamond as well as synthetic diamond, and diamond particles being coated with any suitable coating, e.g. silver.
- the term "effective amount" is understood as an amount that is sufficient to achieve a measurable gloss improvement as compared to the same treatment using a liquid containing no crystallization agent at all.
- Amounts known to be effective are about 1-2 liters of crystallization agent (comprising 2-30 % by weight of e.g. magnesium hexafluorosilicate) per 50 m 2 of floor surface for a single treatment operation.
- amounts known to be effective on an ad-hoc basis range from about 0,4 g of magnesium hexafluorosilicate per m 2 floor surface.
- diluted crystallization agent e.g. at a ratio of 1:100 is also known to be effective when used repeatedly, e.g.
- amounts known to be effective for maintenance on a regular basis range from about 0,004 g of magnesium hexafluorosilicate per m 2 floor surface. It is understood that there are other types of crystallization agents, e.g. zinc hexafluorosilicate, hydrofluoric acid and oxalic acid. The values given above may thus need to be adjusted to apply to the respective type of crystallization agent chosen.
- the combination of a flexible pad and diamond particles provides compensation for unevenness in the surface, and distributes the pressure applied to the pad evenly. Also, this combination, through the flexibility of the pad, considerably reduces the risk of the diamonds scratching the surface.
- diamond particles as abrasive particles when polishing hard stone surfaces provides an effect equal to or better than use of conventional abrasive particles, both in wet and dry conditions.
- the use of diamonds enables the crystallization agent to be abolished, thereby eliminating its handling.
- the abrasive particles have an average diameter of 0.1 to 30 ⁇ m, preferably between 0.1 and 15 ⁇ m and most preferably between 10 and 15 ⁇ m.
- the second portion is substantially free from diamond particles.
- pads according to the invention can be manufactured at a lower cost.
- the tool may be used for and is particularly effective for hard stone or stone-like surfaces, such as granite, concrete, terrazzo, etc.
- the pad consists of a disc-shaped body having a thickness and a first surface, wherein said abrasive particles are present on said first surface and down to a depth from said first surface, which depth is less than said thickness, such that said first portion is at said first surface and said second portion is at a second surface, opposite said first surface.
- the pad consists of a disc-shaped body having a thickness and a first surface, wherein said abrasive particles are present over less than the entire first surface, such that said first and second portions are situated adjacent each other at said first surface.
- This second embodiment facilitates migration of dust and debris into the pad.
- the pad comprises an open, lofty, three dimensional non-woven web, including a plurality of fibers, which are adhered to each other at their points of mutual contact.
- the abrasive particles may be bonded to the fibers of the pad by a secondary binder. Hence, the bonding of the fibers of the pad does not in any way need to be negatively affected by the fact that the abrasive particles are only present at the contact surface.
- the secondary binder may be selected from a group consisting of phenol resin, melamine resin, urea resin and epoxy resin.
- the secondary binder forms a plurality of distinct droplets having a maximum diameter which is smaller than an average length between two points of mutual contact of a fiber.
- the fibers are not entirely coated by the binder resin, facilitating further the migration of dust and debris into the pad.
- the pad may further comprise second abrasive particles selected from a group consisting of graphite, tin oxide, silicon carbide and aluminum oxide.
- the pad is preferably provided in the shape of a circular disc having a diameter between 30 and 100 cm and an uncompressed thickness between 1 and 5 cm.

- FIG. 1b a cross section along the line S1-S2 in Fig. 1a is shown.
- the portion P1 presenting the abrasive particles is present at the first surface A and to a depth D, which is less than the thickness T of the pad 1.
- the second surface B there is a portion P2, which is substantially free from the abrasive particles and the secondary binder.
- portions it is to be understood as a portions of the macrostructure of the pad 1 and not portions of the individual fibers.
- a similar pad 1 there is shown a similar pad 1, the difference being that there is a portion P2' also at the first surface A, which portion P2' is substantially free from the abrasive particles and the secondary binder.
- the abrasive particles are present throughout the secondary binder, and the fibers are bonded to each other by a primary binder and/or by being melt-bonded.
- Fig. 3a is a microscope photograph showing the pad prior to application of the polymer resin/abrasive particles. From Fig. 3a , it can be seen that the fibers constituting the pad are held together at their points 10 of mutual contact by a primary polymer resin.
- the pad is flexible and resilient and comprises polyester and nylon fibers.
- a homogenous polymer resin mixture was prepared, consisting of 200 g PA resin 52-68 phenol resin (available from Perstorp AB, Perstorp, Sweden), 100 g of T-R ⁇ D® ethanol (available from Alfort & Cronholm AB, Bromma, Sweden) and 20 g of LANDS LS600F 4-8 ⁇ m diamond particles (available from Lands Superabrasives, Co., New York, NY, USA).
- PTS 65% p-toluene sulfonic acid
- the resin mixture was sprayed onto a first one A of the surfaces of the polishing pad, using a standard-type compressed air spray gun (normally used for spraying paint).
- the pad with the uncured resin thereafter weighed 173 grams. Subsequently, the pad was placed in a hot air oven at approximately 120°C for approximately 20 minutes.
- Fig. 3b is a microscope photograph.
- Globules or droplets 11 of the resin/particle mixture are formed along each fiber, also between the fibers' points of mutual contact. The droplets are so distributed that the fibers to which they are adhered are not entirely covered.
- Figs 4a-4b show a pad as described above with reference to Figs 1a-1b , and an enlargement of a portion of that pad ( Fig. 4b ), wherein droplets 11 of binder/particle mixture are attached to the fibers.
- each surface portion was first treated with the brown pad and subsequently with the gray pad.
