style="text-indent:25px">中國制造業(yè)的發(fā)展促進(jìn)了紡紗器材的不斷進(jìn)步，目前市場上冶金膠輥膠圈絕大多數(shù)為國產(chǎn)品牌，以較有的器材制造商為主，他們生產(chǎn)的冶金膠輥膠圈占市場總和的80%以上。冶金膠輥由單層、雙層結(jié)構(gòu)發(fā)展到目前的鋁襯結(jié)構(gòu)，冶金膠輥的硬度由高硬度（邵爾 A83 度）發(fā) 展到中低硬度（邵爾 A65 度~邵爾 A72 度），上海冶金膠輥定制，使低硬度高彈性冶金膠輥在純棉精梳紗上得到普遍的應(yīng) 用，改善了紡紗的質(zhì)量；冶金膠輥的表面處理也在逐步發(fā)展，上海冶金膠輥定制，由酸處理，上海冶金膠輥定制、涂料處理（紫外光照處理）到免處理（微處理）等；冶金膠輥膠圈由牛羊皮發(fā)展到丁腈橡膠、聚氨酯等。膠輥采用新型抗靜電劑的優(yōu)化組合提高抗繞性。上海冶金膠輥定制</p><div style="width:100%;text-align: center;"><img

膠圈選用一般掌握“上軟下硬、外軟內(nèi)硬、上松下緊”的原則，實(shí)際應(yīng)用中為了減少走熟期通常采用新舊搭配的方法。一般標(biāo)準(zhǔn)配置為上圈0.9×28×37，下圈1.0×30×83，特殊機(jī)型膠圈的內(nèi)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(xì)微變化，如少數(shù)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(qiáng)調(diào)壽命、耐磨，因此往往選擇膠圈的時(shí)候以厚、硬為原則，不根據(jù)品種、季節(jié)變化等因素做變動，常常出現(xiàn)剛開始上車時(shí)牽伸不開現(xiàn)象。事實(shí)上這是很片面的認(rèn)識，這樣固然延長了使用壽命，卻往往容易使上下膠圈運(yùn)行不同步，嚴(yán)重時(shí)出現(xiàn)打頓現(xiàn)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(shí)也常常出現(xiàn)此現(xiàn)象，主要是板簧上銷缺乏彈性所致。 </p> <p> 根據(jù)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(xiàn)質(zhì)量偏差。或者不考慮成本需要盲目選用比較好次冶金膠輥，導(dǎo)致質(zhì)量過剩及浪費(fèi)。 </p> <p> <br /> 上海冶金膠輥定制膠輥膠圈是對成紗質(zhì)量影響較大的重要紡專器材。</p><div

2）掌握好磨礪時(shí)間，磨礪時(shí)間長的冶金膠輥表面光潔、摩擦因數(shù)小，對纖維握持不利；反之，磨礪時(shí)間短的冶金膠輥表面粗糙度大，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，冶金膠輥受壓大，產(chǎn)生熱量大，易灼傷冶金膠輥表面而影響冶金膠輥性能。 </p> <p> 4）對于免處理冶金膠輥在制作過程中，根據(jù)品種需要考慮是否進(jìn)行光照處理。試驗(yàn)證明，免處理冶金膠輥經(jīng)光照處理后成紗質(zhì)量有所提高，但光照處理的時(shí)間應(yīng)掌握適當(dāng)，試驗(yàn)結(jié)果見表1。 </p> <p> 從試驗(yàn)數(shù)據(jù)來看：冶金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。 </p> <p> 冶金膠輥制作后的檢驗(yàn) </p> <p> 冶金膠輥制作完畢后，上車前應(yīng)按照精磨冶金膠輥技術(shù)標(biāo)準(zhǔn)逐批逐只地對冶金膠輥進(jìn)行檢查。在檢查過程中，對于冶金膠輥直徑、偏心超出允許限度的要堅(jiān)決剔除，導(dǎo)紗動程內(nèi)不允許有砂眼、氣孔，漆頭標(biāo)記要正確無誤。整理后的冶金膠輥外觀應(yīng)以手感無毛刺、不粗糙，滑爽、細(xì)膩為宜。 </p> <p> <br /> </p><p

style="text-indent:25px">目前企業(yè)有一種共識，希望冶金膠輥膠圈的周期越長越好。愿望是美好的，事實(shí)上在國內(nèi)目前技術(shù)的條件下是很難實(shí)現(xiàn)的。只有通過合理的保養(yǎng)、合理的工藝設(shè)備配套才能延長壽命。但實(shí)際使用中卻出現(xiàn)了一個(gè)奇怪的現(xiàn)象，一方面強(qiáng)調(diào)使用周期長，另一方面卻連基本的保養(yǎng)都不做，結(jié)果出現(xiàn)了很多問題，如冶金膠輥膠圈中凹、繞花、開裂，產(chǎn)生了大量的紗疵。其實(shí)通過合理保養(yǎng)延長冶金膠輥膠圈壽命是完全可行的，使用65度不處理冶金膠輥紡純棉緊密紡回磨周期達(dá)六到八個(gè)月，而質(zhì)量基本無影響。他們做法無非是保養(yǎng)到位，如冶金膠輥7天左右下車回彈，加壓適當(dāng)，回磨之前適當(dāng)自然回復(fù)等。一家大型國企使用73度不處理冶金膠輥紡新型纖維素纖維緊密紗時(shí)，回磨周期同樣能做到四個(gè)月以上。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,。上海冶金膠輥定制</p><p
