There is the vinyl tiles of two types.The first vinyl asbestos ceramic tile is equivalent to pitch ceramic tile, different is vinyl type resin but not pitch or other resins are binding agent.For pitch tile floor, use asbestos, pigment and inert filler.

Since about nineteen eighty-two, do not manufacture vinyl asbestos ceramic tile.Remove asbestos, and with other fillers replacement asbestos.This type of floor tile is commonly referred to vinyl compositions ceramic tile (VC ceramic tile).It,, than more porous of vinyl asbestos ceramic tile, therefore is more difficult to produce original gloss.Owing to there being relatively high filer content, these floors only can obtain with ceramic tile form.The recommendation of VC tile floor is safeguarded and is usually directed to waterborne polymeric emulsion coating and aqueous detergent and remover.

VC ceramic tile is made up of the binding agent, filler and the pigment that for example, mix with additive (stabilizing agent and processing aid) conventionally.Binding agent is made up of polymer and/or copolymer, other modified resin and the plasticizer of vinyl chloride.Vinylite is toughness, chemically inert, thermoplastic and resistance to many solvents.For to there is the solid sheet material of different-thickness ((0.32-cm) is the most common for 1/8-inch), and conventionally cut into square (for example 12-inch (30-cm) is square) by heat and pressure are applied to painted vinyl sheet and by vinyl compositions tile forming.VC ceramic tile can provide surface polishing layer, but conventionally in its whole thickness outward appearance for substantially uniform.

The maintenance of the VC tile floor of installing is usually directed to be coated with to obtain gratifying glossiness by several coatings of transparent polymer floor finish, frequent (for example every day) dedusting polishing afterwards, do not clean more continually, and frequently divest and be coated with again by floor finish, to safeguard its outward appearance.

Structured abrasive member can have any shape, for example plate-like, square, daisy shape (daisies), rectangular band, annular, crescent, spirality, wavy line or any 2 dimension geometries.

The example that is applicable to the commercially available structured abrasive member in the present invention comprises, for example, can be used as those of 3M company (3M Company, St.Paul, Minnesota) that 3M TRIZACT DIAMOND HX gold, redness and blue dish derive from Sao Paulo, the Minnesota State.

About the further details of the method for the preparation of structured abrasive member and material is found in for example U.S. Patent No. 5,152, the people such as 917(Pieper) and 5,435, the people such as 816(Spurgeon), 5,437,754 (Calhoun), 5,454, the people such as 844(Hibbard), 5,304, the people such as 223(Pieper) and 7, the people such as 300,479(McArdle) in.

Optional attachment interface system 130 can comprise, for example, and the unci of shackle fastener system, or the people such as end-blocking bar (for example, as people such as U.S. Patent No. 5672186(Chesley) or 5,201,101(Rouser who certainly engages mechanical fastener) described).Optional attachment interface system can comprise multiple elements, for example, with the annulus of the shackle fastener of interface pad (it has the unci of shackle fastener on its opposite flank) combination, is provided for being thus mounted to the hook-shaped outer surface of Mechanical Driven pad.

Suitable optional boundary layer is generally compressible and conformal.Preferably, optional attachment layer has enough general thickness, makes it that structured abrasive member is raise and exceedes the surface of its attached Mechanical Driven pad, makes Mechanical Driven pad significantly not reduce the contact between structured abrasive member and floor surface.Therefore, in certain embodiments, optional boundary layer can have at 2 millimeters to 13 millimeters, the preferred thickness in the scope of 2 millimeters to 5 millimeters.

If there is no optional attachment interface system, can be used for example, some additive methods for mounting mat (adhesive).In this case, and in fact in most of the cases, may it is desirable to structured abrasive member is fixedly installed to compressible Nonwoven Machinery actuator pad with resilience, to be formed for the assembly of structured abrasive member of each type used multiplely.Therefore,, in order to change over another kind from a kind of structured abrasive element type, only need change structure Grinding structural unit/compressible Mechanical Driven pad assembly with resilience, rather than independent structured abrasive member is installed again.

First, second and the 3rd optional structured abrasive member comprise the forming lapping composite (if backing stands to exceed subsidiary deflection, it is easy to be subject to irreversible mechanical failure) that is fixed to conformal backing independently.Each in forming lapping composite comprises the abrasive particle being scattered in the first polymeric binder.Before the particle mean size of the abrasive particle in each continuous structure Grinding structural unit is less than one, produces thus ever-increasing smoothness level, and obtains suitable overall grinding rate simultaneously.

Although the forming lapping composite of structured abrasive member contains ever-reduced granularity, miscellaneous part (for example binding agent abrasive particle composition, conformal backing) and size, shape and/or the layout of grinding composite can change.In some cases, this can cause the increase of the surface roughness of VC tile floor, and conventionally should avoid this combination of structured abrasive member, or carries out other grinding steps so that floor surface is smooth afterwards.For fear of this problem, it is desirable to except the average-size of abrasive particle structured abrasive member substantially the same (for example, with regard to shape, size, composition and the layout of forming lapping composite, the composition of abrasive particle and/or conformal backing).

Mechanical Driven pad can for example, be made by any material (metallic plate, non-woven mat, foam, rubber disc) that can supporting construction Grinding structural unit.In certain embodiments, Mechanical Driven pad can compress and recover and the significant permanent deformation (being that they are compressible and with resilience) of nothing.Compressibility and resilience allow Mechanical Driven pad to float in the irregular part gradually (it can for example be caused by the concrete surface of below) of the height on floor, and rigid mechanical actuator pad may be easy to dig cutter floor (for example depending on floor care Machine Design) in this case.Preferably, Mechanical Driven pad comprises non-woven material, and described non-woven material has dish type (although also can use other shapes), and has the typical thickness of conventional polishing pad institute and compressibility for turning arm polishing machine.For example, Mechanical Driven pad can comprise non woven fibre dish, and described non woven fibre dish has the diameter within the scope of 1 to 5 centimetre of thickness in (cm) scope and 0.3 to 1 meter.Available non-woven material can comprise, for example, synthetic fibers (for example polyester, polyamide, polyolefin and bi-component core-shell synthetic fibers), natural fiber (for example banana, flax, cotton, jute, American aloe, sisal hemp, coconut, soybean and hemp) and aforesaid combination.Mechanical Driven pad can have the abrasive particle that is bonded to non woven fibre.

Fluffy resilient Nonwoven Machinery actuator pad can make according to conventional methods, for example can be purchased from the many machines corporation of the Macedonian orchid in New York (Rando Machine Corporation by using, Macedon, New York) Rando Webber lapper form low-density gas and spin fleece.In certain embodiments, can use the blend of fiber.An exemplary this blend comprises the polyester staple fiber of the melting bonding of polyester (PETG) short fiber and curling skin/core pattern.Fleece optionally heats subsequently in thermal convection current baking oven, with the fiber of any melting bonding in activated fiber net, and the described net that bonds in advance.The example of the fiber of suitable melting bonding is described in U.S. Patent No. 5,082, in 720 (Hayes).Fiber be preferably stretch with curling, but also can be continuous filament yarn, those as formed by extrusion, for example, as U.S. Patent No. 4,227, described in 350 (Fitzer).

Subsequently by making the fleece of optional pre-bonding through between the applicator roll of double roller coating machine, thereby be coated with described fleece, wherein bottom applicator roll part immersion liquid-containing binder resin combination with liquid-containing binder precursor composition.Exemplary liquid-containing binder precursor composition comprises aminoplast, Lauxite, phenolic resins, epoxy resin and carbamate, although also can use other binder precursor.To be placed in the baking oven being heated with solidified liquid binder precursor resin through the nonwoven web of coating subsequently, and make the nonwoven web through bonding.
