公司基本資料信息

 四氟彈性帶又名膨體四氟帶是采用,通過壓條, 高溫拉伸而成,它具有低摩擦系數(shù),它可在下使用適用于反應(yīng)釜、汽輸發(fā)電機(jī)及各種異型口罐、桶的密封。四氟密封帶可在-250℃~+280℃溫度下使用適合于反應(yīng)釜、汽輸發(fā)電機(jī)及各種異形口罐、桶的密封。

可粘貼于法蘭密封面上,使用時(shí)幾乎不存在浪費(fèi)。在中、低壓力下的法蘭密封部位,是一種較為經(jīng)濟(jì)實(shí)用的密封材料。四氟密封帶(PTFE sealing tape)是采用純聚四氟乙烯分散樹脂,通過壓條,高溫拉伸而成,具有低摩擦系數(shù),耐化學(xué)腐蝕、密封性較好等優(yōu)點(diǎn)。
四氟彈性帶使用方法
清理擦干密封面,選擇某一寬度的四氟密封帶,撕去粘膠帶保護(hù)紙,將密封帶粘壓在密封面外沿,兩端頭在某一螺栓處交叉相迭,交叉點(diǎn)以外各余2cm以上(注意:在平面法蘭上使用,兩端頭必須交叉相迭。在凹槽法蘭上使用,可以平行相疊,相疊2cm以上。)合上對應(yīng)密封面,均勻緊固各螺栓,兩端頭交叉部位也會(huì)被壓至與其它部位一樣的厚度,交叉處絕不會(huì)泄漏。
四氟彈性帶特點(diǎn):
1、密封性能好。
密封帶具有高度的可壓縮性,很容易填滿密封面上的空洞和溝槽,堵塞界面泄漏,且在受到張力作用時(shí)有回彈膨脹的特性,因此內(nèi)部介質(zhì)壓力越高,密封力越大,這是密封帶最神奇之特性。
2、使用方便快捷。
剪取一段所需長度的四氟密封帶,只要將兩端頭交叉相迭,即可構(gòu)成一個(gè)任意尺寸、任意形狀的密封圈。附在密封帶一面上的粘膠帶能使密封帶固定在設(shè)備密封面上,以方便安裝,隨后只需不大的螺栓緊固力 ( 最小預(yù)緊力為50Kgf / cm2 )就能形成很好的密封。  ·
3、經(jīng)久耐用。
聚四氟乙烯具有很好的耐腐蝕性、不老化性,經(jīng)過特殊加工的密封帶,又被賦予了很好的耐蠕變性和在很寬的溫度范圍內(nèi)能長期安全使用的性能。  ·
4、清潔干凈。
四氟密封帶為白色聚四氟乙烯制品,因其不會(huì)被腐蝕,不會(huì)老化,因此不會(huì)因脫落而污染所接觸流體。  ·
5、結(jié)濟(jì)合算。
規(guī)格種類繁多的定型密封墊片,需手工裁割或沖制,費(fèi)料費(fèi)工,成本自然不菲,而只要兩端交叉相迭,即可構(gòu)成一個(gè)某一規(guī)格的密封圈,絕無浪費(fèi);很少幾種規(guī)格的密封帶便可應(yīng)付日常所需,省去儲(chǔ)備各種規(guī)格定型密封墊片的昂貴費(fèi)用;膨體聚四氟乙烯密封帶能充分地填充不規(guī)則密封面,可減低密封面的加工精度,并使一些因密封面銹蝕、沖刷、磨損的配件和設(shè)備起死回生;另外因其使用壽命長,維修次數(shù),更顯其經(jīng)濟(jì)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");
