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(duì)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(yàn)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(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：膠輥的表面粗糙度并不是越小越好，應(yīng)掌握在0.5

style="text-indent:25px">粗磨膠輥時(shí)可選用粒度為40、46、54號(hào)，寬度為30 mm的大氣孔砂輪，磨削總量一般為1 mm，可分三次走刀，進(jìn)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(duì)膠輥表面粗糙度無嚴(yán)格要求，主要是保證膠輥表面圓柱度。粗磨后不應(yīng)立即進(jìn)行精磨，要將并條膠輥放置48 h，使其經(jīng)時(shí)效處理后進(jìn)行。精磨膠輥時(shí)可選用粒度為60、70、80號(hào)，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(jìn)行復(fù)磨而不用粗磨，磨削總量一般為0.3 mm～0.4 mm，可分三次進(jìn)行，進(jìn)刀量分別可為0.2 mm、0.1 mm、0.1 mm，采用小負(fù)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(zhì)量，一般砂輪主軸轉(zhuǎn)速為1800 r/min，相應(yīng)車頭轉(zhuǎn)速約為200 r/min。磨削前需要調(diào)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(shè)置為自動(dòng)走刀以保證磨削速度均勻，之后一次走刀速度要慢，以3 m/min～4 m/min為宜。精磨后膠輥膠層應(yīng)細(xì)膩、光滑，目測(cè)其表面無螺旋線，無機(jī)械波紋，表面粗糙度Ra值達(dá)到0.4 μm～0.6 μm為好。上海冶金膠輥有什么用改進(jìn)膠輥軸承的加油方式、控制加油量是保護(hù)膠輥膠圈不被腐蝕、浸透、損傷、損壞的因素之一。</p><div style="width:100%;text-align: center;"><img

冶金膠輥在造紙、印染、印刷、糧食加工、冶金、塑料加工等領(lǐng)域的應(yīng)用性，就要求我們對(duì)冶金膠輥檢測(cè)不得不重視。利用冶金膠輥檢測(cè)得到的數(shù)值，可以幫助我們改進(jìn)相關(guān)的研發(fā)技術(shù)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(diǎn)，但是也有抗壓、抗高溫能力差等缺點(diǎn)，如何提高優(yōu)點(diǎn)，改進(jìn)缺點(diǎn)，也就是冶金膠輥企業(yè)面對(duì)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(yīng)苛刻條件下使用的合成橡膠。如耐高低溫、耐油酸堿介質(zhì)、耐臭氧、耐老化和高氣密性等。 </p> <p> <br /> </p><p> 一般產(chǎn)生吐硬頭和繞冶金膠輥的原因有：溫濕度的變化、纖維含油劑多少、纖維的棉蠟含糖變化情況、纖維的長(zhǎng)度、線密度超出紡紗設(shè)計(jì)要求、特殊纖維的特殊性能等。只有找到吐硬頭繞冶金膠輥的真正原因，做到有的放矢，才能有效的解決問題。在膠圈使用方面的經(jīng)驗(yàn)：膠圈不良直接影響紡紗的順利進(jìn)行，如膠圈表面粘著纖維就會(huì)形成紗疵，影響成紗條干均勻度及單紗強(qiáng)力，造成粗、細(xì)節(jié)及竹節(jié)紗等，絡(luò)筒百管斷頭率明顯增加。另外，由于膠圈不能很好的控制纖維，會(huì)造成成紗節(jié)粗、節(jié)細(xì)，也會(huì)增加細(xì)紗斷頭，增加擋車工的勞動(dòng)強(qiáng)度。 </p> <p> 膠圈不良一般有以下幾種：膠圈內(nèi)徑超差、中凹、表面?zhèn)邸?nèi)層斷裂(或簾子線斷裂)、外層表面老化龜裂、內(nèi)外層不滑爽、有疵點(diǎn)夾入等，有時(shí)還會(huì)產(chǎn)生機(jī)械波。 </p> <p> <br /> 根據(jù)牽伸要求、選型原則選用后區(qū)膠輥，切不可為了節(jié)約盲目選用不合適后膠輥，出現(xiàn)質(zhì)量偏差。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海冶金膠輥有什么用,冶金膠輥"

style="text-indent:25px">膠輥制作完畢后，上車前應(yīng)按照精磨膠輥技術(shù)標(biāo)準(zhǔn)逐批逐只地對(duì)膠輥進(jìn)行檢查。在檢查過程中，對(duì)于膠輥直徑、偏心超出允許限度的要堅(jiān)決剔除，導(dǎo)紗動(dòng)程內(nèi)不允許有砂眼、氣孔，漆頭標(biāo)記要正確無誤。整理后的膠輥外觀應(yīng)以手感無毛刺、不粗糙，滑爽、細(xì)膩為宜。膠輥是紡紗工藝中重要的牽伸部件，其抗繞性、彈性、壓縮變形等性能對(duì)紡紗質(zhì)量有直接的關(guān)系，所以膠輥的制作質(zhì)量、使用方法等直接影響膠輥的性能和使用壽命。膠輥的質(zhì)量主要取決于膠料的配方設(shè)計(jì)，丁腈橡膠(NBR)仍是目前紡紗膠輥的優(yōu)先膠種。膠輥采用新型抗靜電劑的優(yōu)化組合提高抗繞性。上海冶金膠輥有什么用</p><p

style="text-indent:25px">目前大多冶金膠輥膠圈研究或者專題探討會(huì)都在闡述冶金膠輥膠圈的硬度、厚度、冶金膠輥膠圈彈性、使用周期、分散度、橡膠質(zhì)量等問題對(duì)紡紗質(zhì)量的影響。眾所周知,冶金膠輥膠圈具有使用周期,這個(gè)是橡膠廠需要重點(diǎn)解決的問題。我們通過對(duì)上百家紡織廠長(zhǎng)時(shí)間使用同一橡膠廠新舊冶金膠輥膠圈的調(diào)查,對(duì)磨損、劃傷、溝痕和凹凸不平的冶金膠輥膠圈大量的實(shí)地勘察和分析,發(fā)現(xiàn)在冶金膠輥膠圈整體一致使用的情況下,人為因素造成的冶金膠輥膠損壞幾乎占據(jù)了。面對(duì)冶金膠輥膠圈在實(shí)際生產(chǎn)過程中損壞嚴(yán)重的事實(shí),為達(dá)到間接降低紡紗廠生產(chǎn)成本和提高棉紗整體一致性質(zhì)量的目的,紡織廠必須強(qiáng)化管理來減少冶金膠輥膠圈的損傷和損壞。上海冶金膠輥有什么用</p></p><br
