PTFE學名聚四氟乙烯，是一種具有耐熱性、化學惰性、絕緣穩(wěn)定性和低摩擦性的高性能材料，被廣泛用作煎鍋涂層、透氣運動服材料、電子產(chǎn)品絕緣體等。至今尚無有效回收再利用這種材料的方法，而傳統(tǒng)的燃燒處理法不僅易損害燃燒設(shè)備，且會產(chǎn)生高污染氣體。德國拜羅伊特大學上周發(fā)表公報說，該校材料加工學家與企業(yè)界合作，研發(fā)出一種經(jīng)濟有效且無污染的特氟龍材料回收方法。這一成果將有助解決特氟龍垃圾處理問題。德國研究人員首先將這種材料分解成較小的分子，并以微波作為加熱源產(chǎn)生熱解作用，從而使回收率達到93％。間距的測量、調(diào)整內(nèi)容：相鄰葉輪出口間距；首級葉輪與末級葉輪的總間距；相鄰導葉的進口間距；首末級導葉的進口總間距。測量方法及調(diào)整：葉輪間距以葉輪中心現(xiàn)或葉輪的邊緣作基準，用鋼片尺或?qū)Ｓ每ǔ邅頊y量。每一個間距或總間距的誤差，一般不應(yīng)超過或小于規(guī)定1毫米。如不符合要求，應(yīng)進行調(diào)整。調(diào)整的方法，根據(jù)具體情況而定。總間距合乎要求，但有個別間距不合要求，有的間距大，有的間距小，這多半由于葉輪輪轂長短不均。
不要安裝已經(jīng)知道在運輸和存放時已損壞的閥門。安裝之前，檢查并除去所有運輸擋塊、防護用堵頭或墊片表面的蓋子，檢查閥體內(nèi)部以確保不存在異物。采用良好的管接實踐絕大部分的控制閥(調(diào)節(jié)閥)可以安裝在任何位置，通常用的方法是將執(zhí)行機構(gòu)垂直放置并位于閥門的上部。如果執(zhí)行機構(gòu)水平安裝是必須的，則考慮對執(zhí)行機構(gòu)增加一個額外的垂直支撐。應(yīng)確保這樣安裝閥體：流體流向與流向箭頭或指導手冊所指示的方向一致。確保在閥門的上面和下面留有足夠的空間以便在檢查和維護時容易地拆卸執(zhí)行機構(gòu)或閥芯?？臻g距離通常可以從閥門制造商認定的外形尺寸圖上找到。對于法蘭連接的閥體，確保法蘭面準確地對準以使墊片表面均勻地接觸。在法蘭對中后，輕輕地旋緊螺栓，后以交錯形式旋緊這些螺栓。正確地旋緊能避免產(chǎn)生不均勻的墊片負載，并有助于防止泄漏，也有助于避免法蘭損壞或甚至裂開的可能性。當連接法蘭和閥門法蘭材質(zhì)不一樣時，這種預(yù)防措施就顯得尤為重要。
一體化污水處理設(shè)備可以用來處理工業(yè)廢水，按所選擇工藝的性質(zhì)，可分為以下三大類：物理工藝：均化或貯流，吸附，固體顆粒的去除篩除、隔濾、深層過濾、破碎和磨碎，相變----吹脫蒸餾和蒸發(fā)、冷凍、升華。離子交換。膜法-超濾、反滲透、滲析。濾膜。力場分離-離心、重力沉降、溶氣浮選。散氣浮選。表面法-氣泡分離、氣浮、撇除。萃取或吸收。電力及電磁法-紫外線照射、電解。磁分離、電滲析、電子束照射。超聲波法。核輻射法。
一般在帶式輸送機總長度較短時或帶式輸送機雙向運行時采用此方法比較合理，原因是較短帶式輸送機更容易跑偏并且不容易調(diào)整。而長帶式輸送機好不采用此方法，因為調(diào)心托輥組的使用會對輸送帶的使用壽命產(chǎn)生一定的影響。頭部驅(qū)動滾筒或尾部改向滾筒的軸線與輸送機中心線不垂直，造成輸送帶在頭部滾筒或尾部改向滾筒處跑偏。滾筒偏斜時，輸送帶在滾筒兩側(cè)的松緊度不一致，沿寬度方向上所受的牽引力Fq也就不一致，成遞增或遞減趨勢，這樣就會使輸送帶附加一個向遞減方向的移動力Fy，導致輸送帶向松側(cè)跑偏，即所謂的跑松不跑緊。
