    • Provided is a sub-muffler which needs no heat resistant material such as SUS, and which can keep its durability and sound absorbing performance even when the sub-muffler is exposed to various corrosive components in the exhaust gas. At the same time, accomplished is a low-cost manufacture, which is a challenge that sub-mufflers and sound absorbing materials commonly face. Disclosed is a sub-muffler in which a perforated exhaust pipe is arranged, and caps and an out pipe are arranged outside the perforated pipe. Sound absorbing materials are filled in the space between the perforated exhaust pipe, and the caps and the out pipe. The sub-muffler is characterized in that, among the sound absorbing materials, at least part of the sound absorbing material of the perforated pipe side is a basalt fiber for high temperature.
    • 本发明提供一种不需要SUS等耐热材料的副消声器,即使在副消音器暴露于废气中的各种腐蚀性成分的情况下也能够保持其耐久性和吸声性能。 同时,完成了低成本制造,这是子消声器和吸音材料通常面临的挑战。 公开了一种其中布置有穿孔排气管的副消声器,并且在穿孔管的外侧设置有盖和出管。 吸声材料填充在穿孔排气管,盖和出管之间的空间中。 所述副消音器的特征在于,在所述吸声材料中,所述多孔管侧吸声材料的至少一部分为高温玄武岩纤维。

    • Basalt filament is manufactured in such a manner that the fiber diameter can be controlled and the filament is not severed during the winding step. A network former and a glass modifier are formed and maintained with respect to basalt rock ore, and the crystallization and binding of basalt fiber are inhibited, the heat-resistance property of basalt fiber is greatly improved from the conventional 750° C. to 850 or 900° C., and significant cost reduction is achieved over conventional products. The method includes the steps of: grinding basalt rock as a material; washing a resultant ground rock; melting the ground rock that has been washed; transforming a molten product into fiber; and drawing the fiber in an aligned manner, and winding it. The temperature of the molten product in the melting step is 1400 to 1650° C., and logη is 2.15 to 2.35 dPa·s and preferably 2.2 to 2.3 dPa·s, where η is the viscosity of the molten product.
    • 制造玄武岩纤维,使得可以控制纤维直径,并且在卷绕步骤期间丝不被切断。 相对于玄武岩岩石矿形成并保持了网络成型体和玻璃改性剂,并且抑制了玄武岩纤维的结晶和结合,玄武岩纤维的耐热性能从传统的750℃大大提高到850或 900℃,并且比常规产品显着降低成本。 该方法包括以下步骤:将玄武岩岩石作为材料研磨; 清洗所得的地面岩石; 熔化被洗涤的地面岩石; 将熔融产物转化成纤维; 并以对准的方式绘制纤维,并将其卷绕。 熔融步骤中的熔融产物的温度为1400至1650℃,小麦粉为2.15至2.35dPa.s,优选为2.2至2.3dPa.s,其中η为熔融产物的粘度。
