Sealing material, assembly and use of a sealing material
The invention discloses an anti-twisting winding core barrel for winding of water pipe connector PTFE thread seal tape and an anti-twisting mechanism of the anti-twisting winding core barrel, and belongs to the field of building materials. The anti-twisting winding core barrel is mainly suitable for water heating device installation and comprises a winding core barrel body, the center of the winding core barrel body is provided with a central hole, and the two sides of the winding core barrel body are provided with side walls; a hollow setting-out head rotating around the winding core barrel body is arranged between the two side walls and connected to the winding core barrel body through rotary arms movably connected with the winding core barrel body; and the front end of the setting-out head is smaller than the tail end of the setting-out head, and the PTFE thread seal tape is fed from the tail end and discharged from the front end. According to the anti-twisting winding core barrel for winding of the water pipe connector PTFE thread seal tape and the anti-twisting mechanism of the anti-twisting winding core barrel, twisting of the PTFE thread seal tape during using is avoided, construction is convenient, wasting is avoided, meanwhile, materials are saved, and the construction period is shortened.
1 . An article of manufacture for sealing a screw passage through at least two components clamped together by a screw disposed in the screw passage, the article comprising:
a) a plurality of sealing materials, each sealing material having:
a first layer having a thickness d 1 and formed by a textile fabric comprising synthetic fibers, wherein the synthetic fibers are polyester fibers;
a second layer having a thickness d 2 and formed by an adhesive material comprising an adhesive based on butyl rubber and/or epoxy resin, wherein the second layer is in contact with the first layer such that the textile fabric of the first layer is not completely penetrated by the adhesive material thereby providing a first side of the sealing material that is not sticky; and
at least one preformed hole for a screw completely extending through the first layer and the second layer:
wherein the first and second layers are capable of penetrating one another due to a clamping force applied perpendicular to the extension of the layers by the screw such that a sealing layer is formed having a thickness D where 0.9·d 1 ≤D≤1.1·d 1 ;
b) a removable carrier material disposed on a sticky second side of the sealing material, thereby facilitating storage and handling of the sealing material until said carrier material is removed to expose the sticky second side of the sealing material to one of said at least two components having the screw passage, wherein the removable carrier material is in a form of a continuous layer of a disposable paper or film, and having arranged thereon the plurality of the sealing materials wherein the sealing materials are separated from one another by free regions of the carrier material that have no sealing material.
