摘要： The invention is a process for producing a rubber composition containing at least one rubber component (A) selected from natural rubbers and synthetic diene rubbers, a filler containing an inorganic filler (B), a silane coupling agent (C) and a vulcanization accelerator (D), wherein the rubber composition is kneaded in multiple stages, the rubber component (A), all or a portion of the inorganic filler (B), all or a portion of the silane coupling agent (C) and the vulcanization accelerator (D) are added and kneaded in the first stage of kneading, and the specific energy for kneading in the first stage is from 0.05 to 1.50 kWh/kg. The specific energy is obtained by dividing the power consumption by the motor in the kneading device in the first stage of kneading by the total mass of the rubber composition therein. In the process, the coupling function activity can be further increased and a rubber composition favorably having a low-heat-generation property and having good abrasion resistance can be obtained.
摘要翻译：本发明是含有选自天然橡胶和合成二烯橡胶中的至少一种橡胶成分（A），含有无机填充剂（B）的填充剂，硅烷偶联剂（C）和硫化促进剂（（A），全部或部分无机填料（B），全部或部分硅烷偶联剂（C）和硫化促进剂（D）的混合物）在捏合的第一阶段加入并捏合，并且第一阶段捏合的比能量为0.05至1.50kWh / kg。比能量是将第一混炼工序中的混炼装置中的电动机的消耗电力除以橡胶混合物的总质量而得到的。在该过程中，可以进一步提高偶联功能活性，并且可以获得有利地具有低发热性并且具有良好耐磨性的橡胶组合物。

摘要： Sealant in a tire/rim assembly is simply recovered without contaminating the surroundings. With a tire/rim assembly (10) kept sideways, locking between an upper-side bead portion (14) and a rim (18) is released. Next, with the tire/rim assembly (10) kept longitudinally, a tire lever (33) is inserted between the released bead portion (14) and rim (18) to form a clearance (34) between the bead portion (14) and the rim (18). A tube (26) is inserted into the tire through the clearance (34) to recover by sucking sealant (20) in the tire via the tube (26).
