    • 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。

    • A rock wool fiber material is provided to repress crystallization and fixation by forming a network former and a network modifier, to improve heat resistance, and to reduce the cost. The rock wool fiber material consists of basalt and at least one kind of oxide selected from Al2O3(Alumina), SiO2(Silicon Dioxide), CaO(Calcium Oxide), and MgO(Magnesium Oxide). The oxide of a first component is added about 1~40wt.% to the basalt of 100wt.%. The sum of the added amount of the oxide of a second component is 1~70wt.% to the basalt of 100wt.%. The sum of the added amount of the oxide of a third component is 1~60wt.% to the basalt of 100wt.%. The rock wool fiber material is made of two kinds of basalt containing elements at the different content rates.
    • 提供岩棉纤维材料以通过形成网络成型剂和网络改性剂来抑制结晶和固定,以提高耐热性并降低成本。 岩棉纤维材料由玄武岩和选自Al2O3(氧化铝),SiO 2(二氧化硅),CaO(氧化钙)和MgO(氧化镁))中的至少一种氧化物组成。 第一组分的氧化物相对于100重量%的玄武岩加入约1〜40重量%。 第二成分的氧化物的添加量的总和相对于100重量%的玄武岩为1〜70重量%。 第三成分的氧化物的添加量相对于100重量%的玄武岩为1〜60重量%。 岩棉纤维材料由不同含量的两种含玄武岩元素制成。
