A kind of manufacturing process of glass wool

Abstract

The invention provides a manufacture process of glass wool. The manufacture process comprises the following steps: (1) recycling broken glass, cleaning and mashing the recycled broken glass; burdening, meaning mixing the mashed broken glass with the following raw materials in parts by weight: 12-15 parts of sodium carbonate, 10-15 parts of MnO2, 16-18 parts of Cr2O, 30-40 parts of Changbai stones and 12-15 parts of limestones; (2) melting the mixture to obtain uniform and milky molten glass; (3) preparing an adhesive and a water repellent; (4) forming fiber from the molten glass, namely generating fiber from the molten glass in the step (2) to obtain glass wool, and spraying the adhesive and the water repellent; (5) collecting the wool, namely collecting fiber thrown out on a wool collecting net of a wool collector, and air-drying the fiber; (6) spreading the wool, namely forming a plurality of loose glass wool layers by a pendulum machine; (7) pressing the wool, namely pressing the loose glass wool layers by a three-dimensional wool pressing machine; and (8) curing, namely feeding a compact glass wool body pressed by the three-dimensional wool pressing machine into a curing oven for curing, thereby forming a three-dimensional integral structure with an interlayer overlapping structure; and (9) finishing, namely trimming according to specification to obtain the glass wool material.

Description

technical field [0001] The invention relates to a method for making glass wool, in particular to a process for making glass wool. Background technique [0002] Glass wool is an inorganic material, a fiber aggregate made from natural mineral rocks. The general glass wool on the market is made of basalt, and its appearance ranges from light yellow or yellow to brown. [0003] The existing glass wool manufacturing process involves the fibers formed by blown magma filaments formed by melting the ore feedstock, and laying out a loose multi-layer glass wool layer through a pendulum. This multi-layer glass wool passes through the upper and lower rollers of the cotton press machine After compaction, it enters the curing furnace for curing to form glass wool products. Ordinary glass wool produced by this process only has two-dimensional lamination in the thickness direction without cross-linking, so the peel strength is very low. When used as a building material, it is necessary to...

AI Technical Summary

Problems solved by technology

Ordinary glass wool produced by this process only has two-dimensional lamination in the thickness direction without cross-linking, so the peel strength is very low. When used as a building material, it is necessary to use rivets in the thickness direction, etc. The workpiece is further fixed, which affects the construction process and material life, and this kind of penetrating fixation also affects the actual use effect of glass wool, such as affecting its insulation performance
