Description

Technical Field

[0001] The invention relates to the field of rock wool testing, in particular to a positioning tool for rock wool cutting. Background Art

[0002] Rock wool has low thermal conductivity and is an ideal material for building insulation and pipe insulation. Rock wool products are made of high-quality basalt and other materials as the main raw materials. After being melted at a high temperature of more than 1450°C, they are fiberized using the internationally advanced four-axis high-speed centrifugal method. At the same time, a certain amount of adhesive and dust-proof oil are sprayed into them. They are then collected by a cotton collector and processed through a pendulum method. After the cotton is laid in three dimensions, it is solidified and cut to form rock wool products of different specifications and uses.

[0003] As a thermal insulation board, rock wool board has good thermal conductivity and insulation properties. The thermal conductivity coefficient is an important indicator to measure the performance of rock wool board. The smaller the thermal conductivity coefficient, the less energy is transferred through the material, and the better the thermal insulation performance of the thermal insulation rock wool board. Therefore, it is necessary to test the thermal conductivity coefficient of rock wool board. Usually, before testing, the rock wool needs to be cut into the required size. Due to the inconsistent size and thickness of rock wool boards, it is not convenient to position the rock wool during cutting. Therefore, a positioning tool that can position the rock wool for workers to cut is an urgent problem to be solved. Summary of the Invention
