Polyaniline and multi-walled carbon nanotube composite electrode for rechargeable battery

The multi-walled carbon nanotube was introduced into the polymer matrix (PANI) to improve the electric conductivity as well as mechanical properties of the original polymer matrix.PANI/multi-walled carbon nanotube (MWCNT) composites were synthesized via ex-situ and in-situ polymerization to improve their electrical property.And the DC conductivities of PANI/MWCNT according to content and diameter of MWCNT were measured by four-point probe.The highest electric conductivity of PANI/MWCNT composite is 20 S/cm when 0.3% (mass fraction) MWCNTs with 10 nm in diameter and 15 μm in length are added in composite.

疏水阀在半钢轮胎硫化机的节能应用

目前有部分轮胎半钢液压热板式硫化机在热工管路设计时,上下热板和模套的蒸汽管道冷凝水排放采用活塞切断阀方式(也称A/P阀,Air Pison Valve),通过PLC程序控制电磁阀的供/断气来控制切断阀定时排放冷凝水,从而实现蒸汽系统冷凝水的排出,虽然能实现冷凝水的排放,但会带来蒸汽的泄漏浪费,从而带来较大的能耗,本文就切断阀更换为疏水阀,节约蒸汽进行探讨。

3D激光测量系统在轮胎裁断接头检测的应用

目前部分轮胎生产企业的帘布裁断接头测量采用人工测量或背光方式(光源+摄像头)在线测量,只能测量帘布裁断的宽度、错边、开裂等,无法检测帘布裁断的接头量。本文主要讨论的是3D激光三角反射测量法在半钢轮胎生产企业的帘布裁断设备上,测量帘布材料的搭接量、宽度、错边、开裂等应用。

PCR一次法两鼓成型机生产系统性优化

本文主要从PCR一次法两鼓成型机的设备结构和控制系统的组成两方面进行描述,根据现有的PCR成型机存在诸多不足之处,提出相应解决的方案。同时充分应用Motion SFC的自身所体现的高自由度以及可编程性等性质,使机组在复杂工艺条件下执行过程逻辑更加清晰易懂,通过对该机组的程序进行局部的优化和改进,便于维护人员迅速查找故障以便降低停机率。为了提高产能、降低劳动强度等因素增加自动卸胎贴标扫码等装置,最后主要描述了改善后所产生的效益。
