id="mwy8zgd" class="box"><p><p style="text-indent:25px">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。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。產(chǎn)品應(yīng)用在電子、紡織、皮革、家具、玻璃、紙張印刷等領(lǐng)域。根據(jù)產(chǎn)品的使用性能要求，可分為提供耐熱、耐磨、耐油、耐射線、耐酸堿、耐化學(xué)藥品和特殊介質(zhì)的質(zhì)量冶金膠輥。還可根據(jù)客戶需求量身定制個性化冶金膠輥。從紡紗品種、纖維特性、紡紗工藝要求等方面，分析了合理選擇冶金膠輥膠圈硬度、彈性的要素及冶金膠輥膠圈合理搭配使用的方法。針對紡紗過程中冶金膠輥膠圈出現(xiàn)纖維纏繞、表面中凹，上海冶金膠輥批發(fā)公司、須條牽伸不開等問題，提出了解決措施。指出：冶金膠輥膠圈作為重要的牽伸器材，要充分發(fā)揮其在紡紗中的作用，不斷地通過技術(shù)創(chuàng)新生產(chǎn)出更加適應(yīng)不同紡紗品種的冶金膠輥膠圈，上海冶金膠輥批發(fā)公司。認(rèn)為：通過工藝的創(chuàng)新、新材料的應(yīng)用，上海冶金膠輥批發(fā)公司、專件器材的智能制造，可提升冶金膠輥膠圈的質(zhì)量。膠輥膠圈是對成紗質(zhì)量影響較大的重要紡專器材。上海冶金膠輥批發(fā)公司</p><div

style="text-indent:25px">冶金膠輥種類的選擇一般以品種和號數(shù)來決定。純棉品種盡量選擇免處理，但對使用外棉、棉蠟多等原料一般使用微處理冶金膠輥。滌棉品種視混紡號數(shù)盡量使用免處理和微處理冶金膠輥。純滌品種一般選用處理冶金膠輥，但溫濕度控制好的企業(yè)，可選用微處理。用戶的質(zhì)量要求高，一般選用免處理。質(zhì)量要求低，一般選用處理冶金膠輥。這是冶金膠輥種類選擇的基本原則。但不少企業(yè)在選擇時不管什么品種一律選用免處理冶金膠輥，以為這樣就能起到一勞永逸的目的。殊不知，這樣不僅成本增加了，而且在部分品種上也會出現(xiàn)不必要的問題。如在純滌綸品種上，嚴(yán)格意義來說，目前的免處理冶金膠輥是不適用的。主要是其油劑的特殊性和耐磨性要求。如果非要使用，也需要使用特殊的處理方法。這樣處理很多企業(yè)沒有條件，而且其效果甚至不如普通冶金膠輥，往往得不償失。針對品種及質(zhì)量要求選用合適的冶金膠輥種類。純棉一般采用免處理。滌綸及滌綸含量高原則上選用處理或微處理冶金膠輥。上海冶金膠輥批發(fā)公司膠輥在無溶劑復(fù)合設(shè)備***有三支，分布在涂布工位、復(fù)合工位（復(fù)合壓輥），有著非常重要的作用。</p><div

℃~60 ℃），容易纏繞和磨損；冶金膠輥的耐磨性不好，容易損壞冶金膠輥。并條鐵芯采用免維護(hù)鐵芯，鐵芯軸頭與套筒摩擦因數(shù)小、發(fā)熱量小、振動也小，對紡紗質(zhì)量和冶金膠輥的維護(hù)有很大的好處。磨礪后的冶金膠輥表面要滑爽、細(xì)膩，特別是主牽伸冶金膠輥表面粗糙度要小（≤0. 5 μm），以減少纏繞。紡純棉精梳紗品種，主牽伸冶金膠輥一般選用 HA65S 型冶金膠輥（邵爾 A65 度）、Accotex?121 型冶金膠輥（邵爾 A72 度）、新制作或回磨的冶金膠輥上機(jī)，可先在末道磨合幾個班次，再調(diào)到頭道并條使用，有利于減少纏繞。</p><p> 膠輥的質(zhì)量主要取決于膠料的配方設(shè)計，丁腈橡膠(NBR)仍是目前紡紗膠輥的優(yōu)先膠種。配方的確定需要進(jìn)行大量的試驗，其中對性能影響較大的幾種材料可以采用正交法設(shè)計多組方案，再通過機(jī)械性能比較進(jìn)行優(yōu)化，以篩選出理想的配方設(shè)計。 </p> <p> 并條機(jī)膠輥的成型方式一般有三種：直接包膠模壓硫化；膠管擠出一硫化罐硫化成型；鋁襯管膠管套裝成型。第一種成型工藝缺點(diǎn)是效率低、成本高，但比較大優(yōu)點(diǎn)是膠層密實(shí)，膠層與輥芯粘結(jié)牢靠而不會出現(xiàn)脫輥現(xiàn)象，使用壽命長。后兩種制造工藝使用的成型設(shè)備主要為擠出機(jī)和硫化罐，是現(xiàn)在膠輥制造企業(yè)普遍采用的成型工藝。紡紗車間零星和局部的膠輥膠圈纏繞、損壞、損傷是紡織廠生產(chǎn)車間管理控制不到位的結(jié)果。</p><div

2）掌握好磨礪時間，磨礪時間長的膠輥表面光潔、摩擦因數(shù)小，對纖維握持不利；反之，磨礪時間短的膠輥表面粗糙度大，影響成紗質(zhì)量水平。 </p> <p> 3）磨礪量應(yīng)控制在0.15 mm以內(nèi)。磨礪量大，膠輥受壓大，產(chǎn)生熱量大，易灼傷膠輥表面而影響膠輥性能。 </p> <p> 4）對于免處理膠輥在制作過程中，根據(jù)品種需要考慮是否進(jìn)行光照處理。試驗證明，免處理膠輥經(jīng)光照處理后成紗質(zhì)量有所提高，但光照處理的時間應(yīng)掌握適當(dāng)，試驗結(jié)果見表1。 </p> <p> 從試驗數(shù)據(jù)來看：膠輥的表面粗糙度并不是越小越好，應(yīng)掌握在0.5 μm左右；當(dāng)然，表面粗糙度值還應(yīng)根據(jù)纖維性質(zhì)、所紡品種號數(shù)來確定。紡?fù)黄贩N膠輥膠圈使用型號規(guī)格要統(tǒng)一。上海冶金膠輥批發(fā)公司</p><p

了解了冶金膠輥的檢測標(biāo)準(zhǔn)，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(zhì)好壞是要綜合考量的，主要可以從硬度、物理性能、化學(xué)性能、表面特性、其他等方面入手檢測。當(dāng)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(biāo)準(zhǔn)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(biāo)。 </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(qiáng)度、拉伸伸長率、屈撓龜裂、撕裂強(qiáng)度、壓縮長久表現(xiàn)、回彈性、耐油質(zhì)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(xué)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(dǎo)電性、傳熱性、親水性、耐溶劑性 </p> <p> <br /> 上海冶金膠輥批發(fā)公司</p></p><br /><p>文章來源地址:
