嚴(yán)格控制的皮輥表面處理，能夠降低纏花并改善起始生產(chǎn)。即使是當(dāng)今在抗靜電的皮輥遍布天下的時候，我們?nèi)耘f需要在拋光后對皮輥表面進行處理以使纏花降至最低，減少因直接使用拋光皮輥而引發(fā)的問題。現(xiàn)在有很多用化學(xué)制劑進行表面處理的方法，例如用漆、硫酸。這些處理通常能取得不錯的效果，但在處理時必須小心操作，因為使用的是化學(xué)試劑并且通常都是有毒易燃，其中一些試劑非常不穩(wěn)定，會使上羅拉甚至帶槽下羅拉引起氧化。而只要使用特殊的紫外線照射處理皮輥，就完全不必使用污染環(huán)境且有毒的試劑。 光照是極其簡單、快速、經(jīng)濟并且環(huán)保的。精心拋光后的皮輥經(jīng)特殊增強紫外線照射后，其結(jié)構(gòu)發(fā)生改變，結(jié)果是橡膠表面不易磨損纖維。這樣大大減少拋光后的皮輥在運行中產(chǎn)生纏花的可能性，而且世界各地的紡織廠也證明，減少紡紗時的纖維損耗，最初的用于購買紫外光照儀的投資馬上就能收回。 無論是與BERKOL 全自動磨皮輥機中相連的內(nèi)嵌光照模塊指令，還是單獨的光照儀，都具有光照功能，能為前紡端機器處理上羅拉。 BERKOL，唯一能同時提供皮輥和保養(yǎng)皮輥機器的制造商，多年前就已經(jīng)推出了紫外光照儀。憑借多年累積的技術(shù)經(jīng)驗，我們研發(fā)出能給紡紗廠帶來更多效益的全新光照儀：  * 籍可旋轉(zhuǎn)的抽屜設(shè)計，能對皮輥同時進行裝載和光照，提高車間效率 * 高度集中照射密度，特殊研制的1000 瓦紫外燈管和反射器，皮輥受照射時間少 * 最小限度的熱量累積，能使光照儀不間斷工作，極大地提高紫外燈管的效率，延長其 使用壽命 * 低能量消耗、低維護成本，顯著降低生產(chǎn)成本 * 緊湊并且人性化的設(shè)計 * 具有高收益的一筆小的生產(chǎn)投資 * 環(huán)保型機器，被公認(rèn)能改善任何皮輥性能 各種牽伸和紡紗系統(tǒng)的特性決定了對每一種纖維和混紡紗都有特定的紡制要求。當(dāng)今，在許多紡紗應(yīng)用中，對羅拉進行“光照”已經(jīng)成為高效率地產(chǎn)出高質(zhì)量紗線的前提。通過“光照”羅拉，紡紗廠能夠： * 拋光皮輥后減少開機運行問題 * 減少開機運行其間的工作量 * 把纏花減少到最低 * 取得更好的工作運行狀況 * 極大地減少纖維的損耗 * 明顯改善紗線質(zhì)量 * 降低總體成本 光照羅拉能在許多方面顯著改善紡紗機器的運行性能。但是，僅僅依靠光照本身并不能改善拋 光不好的低質(zhì)量皮輥。在光照前，必須對皮輥進行精細(xì)地拋光，而且光照時間也很重要。 BERKOL(R)針對各種應(yīng)用場合和不同條件，提供了推薦方法和相應(yīng)指導(dǎo)。 {英文稿件} HUBER+SUHNER AG Business Unit BERKOL CH-8330 Pfaffikon Tel: +41 (0)44 952 22 11 Fax: +41 (0)44 952 27 60 E-Mail: berkol@hubersuhner.com (R) The new BERKOL Berkolizing machine Reduced lapping for improved start-ups is achieved through carefully controlled cot surface treatment. Even nowadays, with antistatic cots widely available, a treatment of the cot surface after buffing is needed to minimize lapping and to reduce general running-in problems with freshly buffed cots. There are various methods of treatment using chemical agents such as lacquers, sulphuric acid, etc. These treatments often produce good results, but they must be performed with great care, as they involve the use of chemicals and usually toxic agents, which are flammable and some of them are so aggressive that the top rollers – and even the fluted bottom rollers – oxidise. The use of these environment polluting and hazardous chemicals can be completely eliminated by Berkolizing the cots, using special UV rays. Berkolizing is very simple, quick, economical and environment friendly. Radiating the surface of the finely buffed rubber cots with specially developed UV light alters its structure. As a result the rubber surface is less aggressive to the fibers. This considerably reduces the tendency to form laps when running-in freshly buffed cots and as proven in mills around the world, reduces the loss of fibres during spinning to an extent, to which the initial investment in an original Berkolizing machine is quickly recovered. The Berkolizing process is either available as an integrated Berkolizing module, linked to the BERKOL BGS series of fully automatic grinding machines or as a stand-alone model, which also permits to treat top rollers for spinning-preparatory machines. BERKOL, the only manufacturer of cots and roll shop machines, introduced the Berkolizing machine many years ago. The accumulated know how helped us to develop a brand new Berkolizing machine with even more advantages for the spinning mill: * Simultaneous berkolizing and loading of top rollers, thanks to a revolving drawer, increases the efficiency in the roll shop * Especially developed 1000 watt UV lamp and reflectors guarantees short exposure of cots due to highly concentrated and even irradiation intensity * Long life and efficiency of UV lamp is strongly enhanced due to the un-interrupted “running” of the Berkolizer, due to minimal heat build up properties of the UV lamp * Lower energy consumption and low maintenance cost reduce operating costs considerably * Compact and user friendly design * A small investment with very high benefits * Environment friendly and proven process to improve the performance of any cots Each fiber and blend presents specific spinning requirements that vary depending on the characteristics of each drafting system and spinning system. In many spinning applications today, “berkolizing” top rollers has become a prerequisite for efficient and high quality yarn production. By “berkolizing” top rollers, spinning mills achieve: * Reduction of start-up problems after buffing the cots * Reduction of work during start-up period * Minimal lap formation * Better running conditions * Great reduction of fibre loss * Positive influence on yarn quality * General reduction of costs Berkolizing top rollers influences the running characteristics of spinning machines positively in many aspects. However, berkolization cannot improve a poor cot quality and poor finish. Perfect fine buffing is absolutely essential before berkolizing, as well as the time of berkolizing the top rollers. BERKOL(R) provides recommendations and guidelines for each application and condition. New Berkolizing stand alone machine with revolving drawer
