菠萝叶纤维有着天然的抗菌能力,较强的吸湿排汗能力,透气干爽,且具有易纺纱、易漂染、易降解等特点。同时,脱胶工艺是麻类纤维纺纱前的必经工艺处理,主要利用物理和生物的方法从天然菠萝叶片中提取纤维并进行脱胶处理,探讨了脱胶工艺对... 菠萝叶纤维有着天然的抗菌能力,较强的吸湿排汗能力,透气干爽,且具有易纺纱、易漂染、易降解等特点。同时,脱胶工艺是麻类纤维纺纱前的必经工艺处理,主要利用物理和生物的方法从天然菠萝叶片中提取纤维并进行脱胶处理,探讨了脱胶工艺对纤维细度、纤维表面形态、断裂强度及热分解性能的影响。结果表明:物理生物联合脱胶工艺在极大限度减少污染、提高脱胶效率的同时,对菠萝叶纤维的细度、断裂强度不会产生较大影响,纤维的热分解温度升高,并且随着脱胶率的提高,纤维的纵向形态由束状逐渐变成单纤维状态,各项性能也都达到了作为工艺纤维的基本条件。 展开更多

The magnetostrictive liquid level transmitter of offshore platform is mainly used to measure the liquid level height in each tank in the process flow, which has very important value in specific use. Because of the complicated offshore environment, magnetostrictive liquid level transmitter is prone to problems. Once there is a jump, it must be resolved in time to ensure the normal operation of the equipment. This paper introduces the problems and solutions of using magnetostrictive liquid level transducer under the vibration condition of offshore oil platforms. This paper mainly introduces the working principle of magnetostrictive liquid level transducer, analyzes the causes of the "signal jump" problem, and puts forward the proposed solutions. 展开更多
