[0002] Hand-tearable sandpaper, a powerful tool for hand sanding, is indispensable in the industrial field due to its versatility and wide range of applications. Firstly, based on grit size, coarse sandpaper is suitable for quick sanding of rough surfaces, medium sandpaper for further smoothing, and fine sandpaper for fine polishing. Secondly, in terms of material, cloth-based sandpaper is more durable and suitable for heavy-duty sanding, while paper-based sandpaper is the preferred choice for general sanding due to its affordability. Furthermore, hand-tearable sandpaper is specially designed for different materials, such as woodworking, metal, and plastics, to meet specific needs. In terms of application, hand-tearable sandpaper shines in many industries thanks to its portability and ease of use. In the woodworking industry, it is used for fine sanding and polishing of wood; in metalworking, it effectively removes rust and stains, improving surface finish; in plastics processing, it helps improve the surface quality of plastic products. In addition, hand-tearable sandpaper can also be found in industries such as automotive repair, shipbuilding, and stone processing.
[0003] Existing hand-tearable abrasive cloth can be torn off directly for use, but it has the following drawbacks: (1) Existing hand-tearable abrasive cloth is inconvenient to tear because it does not have a pre-set tear, and the torn surface is uneven when it is torn; (2) The abrasive cloth has poor tensile strength and is prone to breakage during use, which affects the sanding. Therefore, we propose an ultra-thin hand-tearable abrasive cloth. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example
[0023] Please see Figures 1 to 6 This utility model provides a technical solution: an ultra-thin hand-tearable abrasive cloth, including an abrasive cloth body 1. The surface of the abrasive cloth body 1 is provided with multiple sets of pre-tear grooves 2. Each set of pre-tear grooves 2 consists of two parts, and the two pre-tear grooves 2 are symmetrically arranged about the abrasive cloth body 1. The cross-section of the pre-tear groove 2 is a rectangular structure. By designing multiple sets of pre-tear grooves 2, pre-tear grooves 2 are opened in advance on the surface of the abrasive cloth body 1 to achieve a thinner thickness at the tearing position of the abrasive cloth body 1. When tearing by hand, the abrasive cloth unit located on one side of the pre-tear groove 2 can be pulled by hand to break along the pre-tear groove 2, making it easy and convenient to tear by hand, and the tear surface is flat. The longitudinal section of the pre-tear groove 2 is a U-shaped structure.
[0024] In this embodiment, preferably, the inner end face of the pre-tear groove 2 is provided with a tear hole 4. The tear hole 4 is designed and opened at the adjacent pre-tear groove 2, which reduces the entanglement area of the gauze body 1 in the pre-tear groove 2, thereby making the hand tearing of this utility model more convenient, easy and smooth. The two ends of the tear hole 4 penetrate through the end faces of the corresponding two pre-tear grooves 2.
[0025] In this embodiment, preferably, the pre-tear groove 2 is provided with a connecting paper strip 3 inside. The connecting paper strip 3 is designed to be a paper structure and is connected to the upper part of the port of the pre-tear groove 2 to connect the port of the pre-tear groove 2, so as to avoid the pre-tear groove 2 opening too large and easily breakage. The connecting paper strip 3 is fixed on the inner wall of the pre-tear groove 2.
[0026] In this embodiment, preferably, the abrasive cloth body 1 is composed of a base cloth 7, a base paper 6, and an abrasive surface 5. The abrasive surface 5 is disposed on the surface of the base paper 6. A titanium-nickel alloy wire 8 is disposed between the base paper 6 and the base cloth 7. The titanium-nickel alloy wire 8 is designed to be woven into a mesh inside the abrasive cloth body 1. The titanium-nickel alloy wire 8 has excellent tensile strength characteristics. By placing it inside the abrasive cloth body 1, the overall tensile strength and strength of the abrasive cloth are improved, and the abrasive cloth is prevented from being torn during use, which would affect the sanding use. The titanium-nickel alloy wire 8 is woven into a mesh inside the abrasive cloth body 1.
[0027] The working principle and usage process of this utility model are as follows: A pre-tear groove 2 is pre-cut on the surface of the abrasive cloth body 1 to reduce the thickness at the tearing point. To prevent the pre-tear groove 2 from opening too wide and easily breaking, a connecting paper tape 3 is used to connect the upper part of the pre-tear groove 2. When tearing by hand, the abrasive cloth unit on one side of the pre-tear groove 2 can be pulled to break along the pre-tear groove 2, making it easy and effortless to tear by hand, and the tear surface is flat. The designed tearing holes 4, located adjacent to the pre-tear groove 2, reduce the connecting area of the abrasive cloth body 1 within the pre-tear groove 2, further making the tearing process easier and smoother. Titanium-nickel alloy wire 8 is woven into a mesh and laid inside the abrasive cloth body 1. Titanium-nickel alloy wire 8 has excellent tensile strength characteristics. Its placement inside the abrasive cloth body 1 improves the overall tensile strength and prevents breakage due to pulling during use, thus affecting sanding performance.
