mm的大氣孔砂輪，磨削總量一般為1 mm，可分三次走刀，進刀量分別可為0.4 mm、0.3 mm、0.3 mm，這樣有利于降低膠輥表面溫度。由于粗磨對膠輥表面粗糙度無嚴格要求，主要是保證膠輥表面圓柱度。粗磨后不應立即進行精磨，要將并條膠輥放置48 h，使其經時效處理后進行。精磨膠輥時可選用粒度為60、70、80號，寬度為30 mm的大氣孔砂輪，磨削總量一般為0.5 mm，棉紡企業(yè)一般*需進行復磨而不用粗磨，磨削總量一般為0.3 mm～0.4 mm，可分三次進行，進刀量分別可為0.2 mm、0.1 mm、0.1 mm，采用小負荷磨削可使膠輥表面熱量受到控制，磨削粉塵也較少，更有利于砂輪的清潔與鋒利。在砂輪安全線速度的前提下，為保證磨礪質量，一般砂輪主軸轉速為1800 r/min，相應車頭轉速約為200 r/min。磨削前需要調整好磨床尾座，保證磨削后膠輥兩端錐度不大于0.03 mm，磨削行程要設置為自動走刀以保證磨削速度均勻，之后一次走刀速度要慢，上海冶金膠輥生產線，以3 m/min～4 m/min為宜。精磨后膠輥膠層應細膩、光滑，目測其表面無螺旋線，無機械波紋，表面粗糙度Ra值達到0，上海冶金膠輥生產線.4 μm～0，上海冶金膠輥生產線.6 μm為好。膠輥存放時相互之間用泡沫塑料隔開或使用**膠輥架，不要直接裸露堆放。上海冶金膠輥生產線</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海冶金膠輥生產線,冶金膠輥"

國產冶金膠輥成紗質量一直比較穩(wěn)定，3個月的試驗數據沒有較大的差異。試驗分析：進口冶金膠輥由于磨礪周期較長，長時間在車上運轉的冶金膠輥易老化，成紗質量隨著冶金膠輥使用周期的延長而有所降低，而國產冶金膠輥由于價格便宜，我廠在制作過程中本著勤磨少磨的原則，即磨礪周期短、回磨量小、回磨次數多，使車上的冶金膠輥總處于良好的紡紗狀態(tài)，成紗質量穩(wěn)定。而且，由于國產冶金膠輥價格較低，我們可以嚴格掌握冶金膠輥的使用周期及回磨周期，不延長使用壽命，對成紗質量的穩(wěn)定非常有利?，F在我廠大部分冶金膠輥為國產冶金膠輥，進口冶金膠輥正逐漸被國產冶金膠輥所替代。 </p> <p> 膠管性能取決于制造廠的產品質量，而紡紗效果則取決于使用廠家的冶金膠輥制作水平，因此，在制作工藝流程中更要關注每個細節(jié)，通過對冶金膠輥嚴格、科學的管理，才能夠穩(wěn)定地提高成紗質量水平，這一點應該受到企業(yè)的重視。 </p> <p> <br /> 上海冶金膠輥質量對平面牽伸來說，膠輥硬度要求比前膠輥高5-10度，直徑要求比前膠輥小0.5mm~1.5mm,。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海冶金膠輥生產線,冶金膠輥"

冶金膠輥在造紙、印染、印刷、糧食加工、冶金、塑料加工等領域的應用性，就要求我們對冶金膠輥檢測不得不重視。利用冶金膠輥檢測得到的數值，可以幫助我們改進相關的研發(fā)技術問題。比如硬度小的冶金膠輥，包容性、彈性好，壓痕范圍寬等優(yōu)點，但是也有抗壓、抗高溫能力差等缺點，如何提高優(yōu)點，改進缺點，也就是冶金膠輥企業(yè)面對解決的問題。特種橡膠也叫特種合成橡膠，是指具有特殊性能和特殊用途能適應苛刻條件下使用的合成橡膠。如耐高低溫、耐油酸堿介質、耐臭氧、耐老化和高氣密性等。 </p> <p> <br /> </p><p> 丁腈再生膠具有和丁腈橡膠一樣的優(yōu)異的耐油性、耐磨性、耐溶劑性等，質量的丁腈再生膠還具有良好的回彈性、較高的拉伸強度，多用于替代丁腈原膠生產印刷冶金膠輥、紡織冶金膠輥等。使用丁腈再生膠生產的冶金膠輥的彈性、硬度、抗靜電性、耐磨性、耐老化性決定了印刷和紡織的質量，各性能直接又相互制約。以丁腈印刷冶金膠輥為例，丁腈再生膠硬度越小，生產出來的冶金膠輥的傳墨性越好、印刷效果越??；但是硬度越小的冶金膠輥抗腐蝕性能越低，生產出來的冶金膠輥又容易受到油墨腐蝕。 </p> <p> 因此使用丁腈再生膠生產冶金膠輥的時候，應該綜合考慮丁腈再生膠的各項指標以及之前的約束關系，合理設計丁腈再生膠冶金膠輥配方，將冶金膠輥的硬明顯降低冶金膠輥成本。 </p> <p> <br /> 軸承選用原則主要是根據膠輥結構的區(qū)分，選用不同規(guī)格的軸承，不能混用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海冶金膠輥生產線,冶金膠輥" src="https://tyunfile.71360.com/WaterMark/UploadFile/wxqzxj/637318170099609375/5044559.png"></div><p> <br /> </p> <p> 了解了冶金膠輥的檢測標準，我們自然要介紹一下冶金膠輥的檢測項目。冶金膠輥的品質好壞是要綜合考量的，主要可以從硬度、物理性能、化學性能、表面特性、其他等方面入手檢測。當然硬度屬于冶金膠輥的物理性能。除此之外，冶金膠輥輥芯在大部分檢測標準中都有提到，所以我們也可以作為冶金膠輥檢測的參考指標。 </p> <p> 冶金膠輥檢測項目主要有： </p> <p> 1、冶金膠輥硬度檢測項目：橡膠國際硬度、趙氏硬度、邵爾A硬度 </p> <p> 2、冶金膠輥用膠料物理性能檢測項目：硬度、硬度公差、拉伸強度、拉伸伸長率、屈撓龜裂、撕裂強度、壓縮長久表現、回彈性、耐油質量變化率、阿克隆磨耗、吸振性、摩擦性能 </p> <p> 3、冶金膠輥用膠料化學性能檢測項目：耐液體性能、耐酸試驗、耐堿試驗、熱空氣老化、耐腐蝕性、導電性、傳熱性、親水性、耐溶劑性 </p> <p> <br /> 膠輥膠圈是對成紗質量影響較大的重要紡專器材。上海冶金膠輥質量</p><p style="text-indent:25px">膠輥的制作質量、使用方法等直接影響膠輥的性能和使用壽命。上海冶金膠輥生產線</p><p> 膠圈選用一般掌握“上軟下硬、外軟內硬、上松下緊”的原則，實際應用中為了減少走熟期通常采用新舊搭配的方法。一般標準配置為上圈0.9×28×37，下圈1.0×30×83，特殊機型膠圈的內徑可能會有不同要求，特別工藝要求的膠圈厚度也可能會有細微變化，如少數工廠紡高支紗采用較小的鉗口隔距，上圈采用0.85mm，下圈采用0.9mm厚度的配置。膠圈選用的誤區(qū)主要是片面強調壽命、耐磨，因此往往選擇膠圈的時候以厚、硬為原則，不根據品種、季節(jié)變化等因素做變動，常常出現剛開始上車時牽伸不開現象。事實上這是很片面的認識，這樣固然延長了使用壽命，卻往往容易使上下膠圈運行不同步，嚴重時出現打頓現象，造成大量的紗疵。這種情況在粗紗更明顯，主要是粗紗加壓重、定量大所致。板簧加壓時也常常出現此現象，主要是板簧上銷缺乏彈性所致。 </p> <p> 根據牽伸要求、選型原則選用后區(qū)冶金膠輥，切不可為了節(jié)約盲目選用不合適后冶金膠輥，出現質量偏差?；蛘卟豢紤]成本需要盲目選用比較好次冶金膠輥，導致質量過剩及浪費。 </p> <p> <br /> 上海冶金膠輥生產線</p></p><br /><p>文章來源地址:
