Abstract
The invention discloses a production process of sandwich cotton for color steel sandwich compounding. The production process specifically includes the following steps: A, feeding raw materials including 62.5-67.5% of SiO2, 5.5-7% of B2O3, 10.5-12% of CaO and MgO, 0.0-1.0% of Fe2O3, 0.7-3.0% of Al2O3 and 14.5-18.0% of K2O and Na2O according to a certain sequence, and mixing the raw materials, wherein the temperature during preparation is 35-45 DEG C; B, feeding the mixed materials into a kiln, and increasing the temperature for melting; C, monitoring and ensuring the continuity and uniformity in feeding by an automatic liquid level control system, and recycling waste gases, wherein the measurement error of a laser liquid level indicator is +/-0.5mm; D, allowing the melted raw materials to flow into a centrifuge, drawing fiberglass, and feeding high-bonding-strength adhesives and air atomized glue sprays to the lower portion of the centrifuge to form the sandwich cotton. The sandwich cotton produced by the production process has the felt properties of glass cotton rolls and the compression strength of glass cotton strips, has high hydrophobicity, and has the advantages of noise reduction, insulation, high corrosion resistance, high mechanical strength and the like.
Description
technical field [0001] The invention relates to the field of color steel sandwich compounding, in particular to a production process of bread cotton for color steel sandwich compounding. Background technique [0002] The design of the steel structure factory building is generally two layers of steel plates filled with glass wool. The construction steps are to first lay the first layer of steel plates, then lay the glass wool roll felt insulation layer, and finally lay the second layer of steel plates. The selected density of glass wool roll felt is generally 12K-16K. It can be seen that this construction method has cumbersome steps, heavy labor, high cost and high risk factor. With the continuous development of industry technology, automatic composite technology has been gradually researched, that is, the thermal insulation cotton is cut into strips and turned over, and then composited with two layers of steel plates by sizing and heating, and the appropriate width and lengt...
