產(chǎn)品詳情
PTFE學(xué)名聚四氟乙烯,是一種具有耐熱性、化學(xué)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(yùn)動(dòng)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(huì)產(chǎn)生高污染氣體。德國拜羅伊特大學(xué)上周發(fā)表公報(bào)說,該校材料加工學(xué)家與企業(yè)界合作,研發(fā)出一種經(jīng)濟(jì)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(dá)到93%。間距的測(cè)量、調(diào)整內(nèi)容:相鄰葉輪出口間距;首級(jí)葉輪與末級(jí)葉輪的總間距;相鄰導(dǎo)葉的進(jìn)口間距;首末級(jí)導(dǎo)葉的進(jìn)口總間距。測(cè)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(zhǔn),用鋼片尺或?qū)S每ǔ邅頊y(cè)量。每一個(gè)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(jìn)行調(diào)整。調(diào)整的方法,根據(jù)具體情況而定??傞g距合乎要求,但有個(gè)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(yùn)輸和存放時(shí)已損壞的閥門。安裝之前,檢查并除去所有運(yùn)輸擋塊、防護(hù)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(shí)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(jī)構(gòu)垂直放置并位于閥門的上部。如果執(zhí)行機(jī)構(gòu)水平安裝是必須的,則考慮對(duì)執(zhí)行機(jī)構(gòu)增加一個(gè)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(dǎo)手冊(cè)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(hù)時(shí)容易地拆卸執(zhí)行機(jī)構(gòu)或閥芯??臻g距離通??梢詮拈y門制造商認(rèn)定的外形尺寸圖上找到。對(duì)于法蘭連接的閥體,確保法蘭面準(zhǔn)確地對(duì)準(zhǔn)以使墊片表面均勻地接觸。在法蘭對(duì)中后,輕輕地旋緊螺栓,后以交錯(cuò)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(fù)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(dāng)連接法蘭和閥門法蘭材質(zhì)不一樣時(shí),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(chǎng)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(jī)總長度較短時(shí)或帶式輸送機(jī)雙向運(yùn)行時(shí)采用此方法比較合理,原因是較短帶式輸送機(jī)更容易跑偏并且不容易調(diào)整。而長帶式輸送機(jī)好不采用此方法,因?yàn)檎{(diào)心托輥組的使用會(huì)對(duì)輸送帶的使用壽命產(chǎn)生一定的影響。頭部驅(qū)動(dòng)滾筒或尾部改向滾筒的軸線與輸送機(jī)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(shí),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(shì),這樣就會(huì)使輸送帶附加一個(gè)向遞減方向的移動(dòng)力Fy,導(dǎo)致輸送帶向松側(cè)跑偏,即所謂的跑松不跑緊。
