Background technology
About the cleaning of floor surface or slightly polish the known pad that is to use the dimensional non-woven web form (non-woven web pad).Pad is provided with circular discoid body usually; It is releasably attached on the circular loading plate; In use it is rotated by being impelled in being parallel to the plane of floor surface, so that when pad contact with floor surface, fills up that quilt slightly compresses through resulting from the pressure between floor surface and the loading plate.Loading plate is driven by motor usually and can be installed on the bearing frame, and this bearing frame can be arranged as by the operator in the walking and promote or pulling maybe can be set to the vehicle that can drive.
This pad is formed by organic material fiber, for example polyamide and/or polyester, particularly polyethylene terephthalate (polyethylene terephtalate).In some cases, fiber also comprises natural fiber, like walnut fiber or cocoanut fiber.
The fiber of pad can be located mutual connection being in contact with one another of they through so-called melting adhered (melt bonding), and fiber experience can make the heat that the outside of fiber is melted slightly and coupled together mutually thus thus.
Alternatively or extraly, fiber can interconnect at their place that is in contact with one another---to be called " main bonding agent " in the literary composition of back---through filling up injection of polymer resin (polymer resin).
The production of such non-woven mat has been known, US-A-3 for example, and 537,121, US-A-4,893,439, EP-A-0 397 374, GB-A-1 348 526 and EP-B-0 562 919, and do not need thus to further describe in this article.
US-A-3,537,121 have disclosed the pad that is used for polished aluminum, plastics, wax and similar surfaces.US-A-3,537,121 have also disclosed the production of this pad.At US-A-3, in 537,121; Through pad is passed through between a pair of compression roller; One of them compression roller partly immerses in the container of mixing of adhesive resin and abrasive grains, and the adhesive application of mixing with abrasive grains thus is on this pad, and after this pad is allowed to sulfuration (cure) or dry.Thus, at US-A-3, a kind of pad is provided in 537,121, it is poured into by bonding agent and abrasive grains fully.
US-A-4,893,439 disclose a kind of pad that is used to polish floor surface or aluminium.This pad is made up of organic material fiber and is constituted non-woven structure fluffy (lofty), open, and contains abrasive grains is bonded to the bonding agent on the fiber.US-A-4, the void ratio US-A-3 that the spacer in 893,439 has, bigger in 537,121, and have the ability of the absorption dust of improvement thus, so that it can use the longer time.Also have, US-A-4, the pad that discloses in 893,439 is poured into by bonding agent and abrasive grains fully.
EP-A-0 397 374 has disclosed a kind of pad that is used for the floor polishing machine, and it is also poured into by bonding agent and abrasive grains fully.
The pad of the above-mentioned type is through being usually used in what is called " polishing (bumishing) "; Promptly with very high speed (1500-3000rpm) and relatively low pressure drying polishing (normally daily use) is carried out on the unusual surface of mild wear, purpose is to recover through polished surface.Such processing is generally used for vinyl ground and marble ground.The pad that is suitable for this purpose can be by 3M
