Method of manufacturing glass fiber products with waste glass fiber, which comprises the following steps: waste glass fibers into the furnace, the average length of waste glass fiber is less than 12 inches (305mm), which can be composed of inorganic fibrosis and glass fiber product components were similar, at least some of the waste glass fiber coated with organic compounds the molten pool, the feeding speed is sufficient to maintain a molten glass in the furnace, and in a eight hour period of the molten pool changes in level remained at about less than 0.35 inches (9mm) range; in the melting temperature of at least enough at least in the molten glass pool of waste glass fiber added near the mouth to keep oxidizing atmosphere, and not in the glass glass forming material into the furnace under the condition of melting the waste glass fiber, The molten glass is pulled out from the furnace; adjust the furnace temperature below the glass melt temperature, which has formed the viscosity; and preparation of glass fiber products from the bushings at least one suitable for the glass melt adjusted, and an approximately constant pulling speed, the molten glass from pot out of glass fiber products made of the provisions of the.
【技术实现步骤摘要】
本专利技术涉及用废玻璃纤维(包括带有有机化合物涂层和含一定量的水分的玻璃纤维)制造连续的玻璃纤维丝的方法和装置。制成的连续玻璃纤维丝制品有多种形式，包括筒管上的纺织丝和纱；一根或多根玻璃纤维丝或束(称为“粗纱”)的织物和筒子卷装中的丝和纱；以及由连续玻璃纤维丝用湿切法或干切法加工成的切碎玻璃纤维线。在成功地制成的玻璃纤维制品中，严格地控制纤维的玻璃组分的粉末状批料，这有利于形成玻璃纤维的连续长度，并且有利于形成卷绕丝的完整卷装，而很少出现诸如碎石、气泡和凸纹之类的缺陷。将批料熔化和精炼并通过一拉丝漏板或喷丝板制成玻璃纤维，上述的漏板或喷丝板通常是作为在玻璃熔化炉的前炉中的若干漏板或喷丝板工位中的一个来设置的。该漏板和喷丝板带有若干个细孔，熔融玻璃流从这些细孔被拉细并快速冷却而成玻璃纤维。在从漏板制造连续纤维或长丝的过程中由一台卷绕机提供拉力并将玻璃熔体拉细。在制造玻璃纤维时，可在制造过程的各个区对纤维进行各种类型的化学处理，例如，在拉出连续玻璃纤维并进行冷却后，通常立刻对纤维进行化学涂层。这种含有有机化合物的涂层至少可以足够防止在随后聚集成纤维束时特别是在进...
