 四氟弹性带又名膨体四氟带是采用,通过压条, 高温拉伸而成,它具有低摩擦系数,它可在下使用适用于反应釜、汽输发电机及各种异型口罐、桶的密封。四氟密封带可在-250℃~+280℃温度下使用适合于反应釜、汽输发电机及各种异形口罐、桶的密封。
可粘贴于法兰密封面上,使用时几乎不存在浪费。在中、低压力下的法兰密封部位,是一种较为经济实用的密封材料。四氟密封带(PTFE sealing tape)是采用纯聚四氟乙烯分散树脂,通过压条,高温拉伸而成,具有低摩擦系数,耐化学腐蚀、密封性较好等优点。
四氟弹性带使用方法
清理擦干密封面,选择某一宽度的四氟密封带,撕去粘胶带保护纸,将密封带粘压在密封面外沿,两端头在某一螺栓处交叉相迭,交叉点以外各余2cm以上(注意:在平面法兰上使用,两端头必须交叉相迭。在凹槽法兰上使用,可以平行相叠,相叠2cm以上。)合上对应密封面,均匀紧固各螺栓,两端头交叉部位也会被压至与其它部位一样的厚度,交叉处绝不会泄漏。
四氟弹性带特点:
1、密封性能好。
密封带具有高度的可压缩性,很容易填满密封面上的空洞和沟槽,堵塞界面泄漏,且在受到张力作用时有回弹膨胀的特性,因此内部介质压力越高,密封力越大,这是密封带最神奇之特性。
2、使用方便快捷。
剪取一段所需长度的四氟密封带,只要将两端头交叉相迭,即可构成一个任意尺寸、任意形状的密封圈。附在密封带一面上的粘胶带能使密封带固定在设备密封面上,以方便安装,随后只需不大的螺栓紧固力 ( 最小预紧力为50Kgf / cm2 )就能形成很好的密封。  ·
3、经久耐用。
聚四氟乙烯具有很好的耐腐蚀性、不老化性,经过特殊加工的密封带,又被赋予了很好的耐蠕变性和在很宽的温度范围内能长期安全使用的性能。  ·
4、清洁干净。
四氟密封带为白色聚四氟乙烯制品,因其不会被腐蚀,不会老化,因此不会因脱落而污染所接触流体。  ·
5、结济合算。
规格种类繁多的定型密封垫片,需手工裁割或冲制,费料费工,成本自然不菲,而只要两端交叉相迭,即可构成一个某一规格的密封圈,绝无浪费;很少几种规格的密封带便可应付日常所需,省去储备各种规格定型密封垫片的昂贵费用;膨体聚四氟乙烯密封带能充分地填充不规则密封面,可减低密封面的加工精度,并使一些因密封面锈蚀、冲刷、磨损的配件和设备起死回生;另外因其使用寿命长,维修次数,更显其经济合算ta:image/svg+xml;charset=utf-8,%3Csvg class='icon' viewBox='0 0 1024 1024' xmlns='http://www.w3.org/2000/svg' width='200' height='200'%3E%3Cdefs%3E%3Cstyle%3E@font-face{font-family:feedback-iconfont;src:url(//at.alicdn.com/t/font_1031158_1uhr8ri0pk5.eot?%23iefix) format(%26apos;embedded-opentype%26apos;),url(//at.alicdn.com/t/font_1031158_1uhr8ri0pk5.woff2) format(%26apos;woff2%26apos;),url(//at.alicdn.com/t/font_1031158_1uhr8ri0pk5.woff) format(%26apos;woff%26apos;),url(//at.alicdn.com/t/font_1031158_1uhr8ri0pk5.ttf) format(%26apos;truetype%26apos;),url(//at.alicdn.com/t/font_1031158_1uhr8ri0pk5.svg%23iconfont) format(%26apos;svg%26apos;)}%3C/style%3E%3C/defs%3E%3Cpath d='M862.057 708.024H774.74a22.958 22.958 0 0 0-22.565 23.35V910.72a23.743 23.743 0 0 0 6.671 16.483 21.78 21.78 0 0 0 15.894 6.671h87.318a21.584 21.584 0 0 0 15.698-6.671 23.743 23.743 0 0 0 6.672-16.483V731.57a24.724 24.724 0 0 0-6.476-16.678 22.565 22.565 0 0 0-15.894-6.868z' fill='%23ddd'/%3E%3Cpath d='M861.861 517.886h-699.92a22.958 22.958 0 0 0-22.76 23.547v89.476a22.958 22.958 0 0 0 22.76 22.958h268.43a14.913 14.913 0 0 1 14.717 14.913v242.136a22.958 22.958 0 0 0 6.672 16.287 22.173 22.173 0 0 0 15.894 6.671h88.3a22.173 22.173 0 0 0 15.893-6.671 22.958 22.958 0 0 0 6.671-16.287V668.387a15.698 15.698 0 0 1 4.317-10.792 14.717 14.717 0 0 1 10.4-4.317h268.626a22.958 22.958 0 0 0 22.958-23.154v-88.691a22.958 22.958 0 0 0-22.958-23.547z' fill='%23ddd'/%3E%3Cpath d='M261.033 708.024h-87.318a22.958 22.958 0 0 0-22.565 23.35V910.72a23.743 23.743 0 0 0 6.671 16.483 21.78 21.78 0 0 0 15.894 6.671h87.318a22.37 22.37 0 0 0 15.894-6.671 24.724 24.724 0 0 0 6.476-16.68V731.375a22.958 22.958 0 0 0-22.37-23.35zm213.292-427.761h87.122q22.566 0 22.566 22.565v145.007q0 22.566-22.566 22.566h-87.122q-22.565 0-22.565-22.566V302.828q0-22.565 22.565-22.565zM161.746 90.125H861.86q22.566 0 22.566 22.565v85.553q0 22.565-22.566 22.565H161.746q-22.566 0-22.566-22.565V112.69q0-22.565 22.566-22.565zm612.993 190.138h87.122q22.566 0 22.566 22.565v145.007q0 22.566-22.566 22.566H774.74q-22.565 0-22.565-22.566V302.828q0-22.565 22.565-22.565zm-601.024 0h87.122q22.566 0 22.566 22.565v145.007q0 22.566-22.566 22.566h-87.122q-22.565 0-22.565-22.566V302.828q0-22.565 22.565-22.565z' fill='%23ddd'/%3E%3C/svg%3E");
