Abstract

The invention relates to a self-demolding net strip for glass cotton. The self-demolding net strip comprises a flexible surface layer, a middle support player and a bottom layer. The self-demolding net strip is characterized in that the flexible surface layer is a composite membrane material with low surface energy; the middle support player is of a structure in which trapezoid modules are continuously embedded; the thickness of the bottom layer is 1mm-5mm; round small holes with the radiuses of 0.5mm-2mm are uniformly formed in the net strip. The self-demolding net strip has the beneficial effects that (1) the demolding is easy; (2) the glass is not easily attached to a cotton collection net strip, so that the production process is clean and sanitary; and (3) a glass cotton product can be automatically separated from the net strip, the structure and the performance of the glass cotton product are not damaged, and the prepared glass cotton product is relatively long in service life and relatively stable in performance.

Description

technical field [0001] The invention relates to a mesh belt structure, in particular to a glass wool self-release mesh belt. Background technique [0002] The technology of glass wool prepared by flame blowing method has been widely used in actual production since its formation. At present, glass wool products prepared by flame blowing method are widely used in the field of filtration, and the technology is also very mature. However, flame blowing Raw cotton products prepared by traditional methods are difficult to be prepared into felt-like products, which greatly limits the application form and stability of flame cotton, and causes great inconvenience to its application and promotion. [0003] The reason why it is difficult to prepare flame cotton products into felt products is mainly because the fiber diameter of glass wool products prepared by flame blowing method is thin and short, which is easy to cause the fibers to be entangled with the cotton-collecting mesh belt, w...
