id="88yyfcy" class="box"><p><p> 國內(nèi)棉紡行業(yè)的發(fā)展快速，緊密紡、賽絡(luò)紡、嵌入紡等紡紗工藝日趨成熟，高效率、高效益紡紗帶來紡織機(jī)械高速化，紡紗品種多樣化 (粘膠、天絲、莫代爾、絹絲等)，形成的技術(shù)重要是紡紗高速化、前紡重定量、細(xì)紗大牽伸、紗線***的紡紗工藝,對冶金膠輥帶來四方面新問題。 </p> <p> （1）工作溫度上升。橡膠體工作中產(chǎn)生的熱量與工作速度、受壓以及摩擦量有關(guān)。在高壓高速條件下，單位時間內(nèi)冶金膠輥形變數(shù)量增多，上海冶金膠輥哪家專業(yè)，橡膠分子鍵容易因不斷快速蠕變而僵硬。 </p> <p> （2）摩擦量增加。高速條件下，單位時間內(nèi)纖維通過冶金膠輥的次數(shù)增加，冶金膠輥的磨耗量增加。 </p> <p> （3）高速、高壓條件下，膠體的形變力大于形變次數(shù)，冶金膠輥與鐵芯的結(jié)合面受到剪切力和剝離力增大，上海冶金膠輥哪家專業(yè)。 </p> <p> （4）新型纖維紡紗，對冶金膠輥耐油性，上海冶金膠輥哪家專業(yè)、抗靜電性提出了更高的要求。 </p> <p> <br /> 注重膠輥膠圈保養(yǎng)，制定合理的保養(yǎng)周期。上海冶金膠輥哪家專業(yè)</p><div

1）磨礪好的冶金膠輥在存放時應(yīng)避免光線照射，避免引起受光面膠層老化，影響成紗質(zhì)量。 </p> <p> 2）把好冶金膠輥上車前、后的質(zhì)量關(guān)，加強(qiáng)檢查考核力度。冶金膠輥上機(jī)前逐只檢查，保證上車冶金膠輥全部合格，在將冶金膠輥上車前保全隊(duì)與冶金膠輥工段做好交接驗(yàn)收工作。冶金膠輥上車后，保全隊(duì)與擋車工進(jìn)行交接驗(yàn)收；在交接班時，要交接冶金膠輥的運(yùn)轉(zhuǎn)質(zhì)量情況，責(zé)任分清。 </p> <p> 3）安排專人對重點(diǎn)區(qū)域、重點(diǎn)品種進(jìn)行機(jī)上冶金膠輥動態(tài)檢查，對于跳動超標(biāo)、手感不良、出現(xiàn)中凹或損壞的冶金膠輥及時更換。 </p> <p> 4）大小平車、校錠機(jī)臺要校對搖架壓力，保證同臺壓力一致。 </p> <p> 5）橫動裝置靈活有效，橫動量符合標(biāo)準(zhǔn)要求。橫動裝置失靈或橫動量過小，易導(dǎo)致冶金膠輥過早磨損、中凹，影響條干CV值，嚴(yán)重時會在布面上造成條干疵布。 </p> <p> <br /> 上海冶金膠輥哪家專業(yè)下班后或長時間不使用，應(yīng)將膠輥與網(wǎng)紋輥分離開，避免壓傷膠輥而出現(xiàn)傳墨不均勻的線條。</p><div

N），冶金膠輥耐磨性要好。冶金膠輥的硬度一般選擇邵爾A72 度~ 邵爾 A83 度），如WRC?975型冶金膠輥（邵爾A72 度）、J?490A 型冶金膠輥（邵爾 A83 度）等。另外一種的細(xì)紗冶金膠輥，他的選型非常重要，如果選型不當(dāng)，不但影響到紡紗的質(zhì)量、造成纏繞冶金膠輥，還影響到細(xì)紗機(jī)的效率、產(chǎn)量和專件器材的消耗。由于細(xì)紗工序紡紗品種多，品種翻改頻繁，造成了膠輥的型號和種類多。我公司純棉精梳紗產(chǎn)品定位高，一般選用 J?463A 型冶金膠輥（邵爾 A63 度左右）和 WRC ?365 型冶金膠輥（邵爾 A65 度左右）。采用全自動磨冶金膠輥機(jī)，磨礪后的冶金膠輥粗糙度一般在0. 5 μm~ 0. 7 μm，上機(jī)后的冶金膠輥無纏繞現(xiàn)象，紡紗質(zhì)量指標(biāo)穩(wěn)定，符合純棉精梳紗的要求。</p><p> 我們在印刷機(jī)印刷東西的時候，經(jīng)?？梢钥吹綑C(jī)器的兩側(cè)有棍，那這種棍大家知道是什么嗎？其實(shí)，它的名字叫做冶金膠輥。冶金膠輥是以金屬或其他材料為芯，外覆橡膠經(jīng)硫化而制成的輥狀制品。冶金膠輥按用途可分為:造紙冶金膠輥、印染冶金膠輥、印刷冶金膠輥、礱谷冶金膠輥、冶金膠輥及油印冶金膠輥等；按表面形態(tài)可分為：平輥和花紋冶金膠輥；按材料又可分為：丁基冶金膠輥、丁腈冶金膠輥、聚氨酯冶金膠輥及硅橡膠冶金膠輥等。冶金膠輥一般由外層膠、硬質(zhì)膠層、金屬芯、輥頸和通氣孔組成，其加工包括輥芯噴砂、黏合處理、貼膠成型、包布、鐵絲纏繞、硫化罐硫化及表面加工等工序。冶金膠輥主要應(yīng)用于造紙、印染、印刷、糧食加工、冶金、塑料加工等方面。 </p> <p> <br /> </p> <p> <br /> 傳統(tǒng)認(rèn)為膠輥表面粗糙度越小越好，膠輥表面細(xì)膩，不易繞花，從而達(dá)到膠輥“光，滑，燥，爽”的四點(diǎn)要求。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

線槽問題是軟冶金膠輥使用中碰到的常見問題，許多企業(yè)從高硬度冶金膠輥改用軟冶金膠輥時如果不注意工藝配套及采取合適的處理方法就會產(chǎn)生大量的線槽皮輥，企業(yè)技術(shù)人員在處理此問題時常常發(fā)生誤區(qū)，不加分析，一概認(rèn)為是冶金膠輥質(zhì)量造成的，結(jié)果貽誤了許多時間，造成了大量的浪費(fèi)。固然冶金膠輥彈性太差有可能有此現(xiàn)象，但是對新冶金膠輥來說，其概率就微乎其微了。真正的原因應(yīng)該是除了冶金膠輥選型不當(dāng)外，主要有以下幾種，一是操作不當(dāng)，粗紗搓卷接頭或細(xì)紗換粗紗時塞包卷造成冶金膠輥損傷。二是鋼領(lǐng)鋼絲圈質(zhì)量太差或配套不合理引起飛圈粘附在冶金膠輥上造成冶金膠輥損傷。三是羅拉清潔不及時，羅拉上粘附雜物引起壞冶金膠輥。四是工藝不當(dāng)，采用臨界工藝造成牽伸力急劇波動造成冶金膠輥拉傷。這種關(guān)鍵因素，因?yàn)橹挥羞@類因素才會造成大面積損傷。這種現(xiàn)象的處理也很簡單，就是根據(jù)質(zhì)量要求合理配置工藝，避免臨界工藝。另外，如果冶金膠輥處理適當(dāng)如采取光照處理增大冶金膠輥表面的耐磨性能也會減少此現(xiàn)象。 </p> <p> <br /> 膠輥的制作是在無縫鋼管的表面上包裹一層橡膠，膠層的厚度至少要在10mm以上。上海冶金膠輥哪家專業(yè)</p><p style="text-indent:25px">膠輥膠料要具備較低的壓縮變形和耐磨性，膠輥配方、工藝設(shè)計(jì)創(chuàng)新要點(diǎn)。上海冶金膠輥哪家專業(yè)</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(zhì)量的丁腈再生膠還具有良好的回彈性、較高的拉伸強(qiáng)度，多用于替代丁腈原膠生產(chǎn)印刷冶金膠輥、紡織冶金膠輥等。使用丁腈再生膠生產(chǎn)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(zhì)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(chǎn)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(chǎn)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(chǎn)冶金膠輥的時候，應(yīng)該綜合考慮丁腈再生膠的各項(xiàng)指標(biāo)以及之前的約束關(guān)系，合理設(shè)計(jì)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 /> 上海冶金膠輥哪家專業(yè)</p></p><br /><p>文章來源地址:
