再用洗車(chē)水或汽油把殘留在橡膠輥上的煤油和浮石粉清洗干凈，重新安裝和調(diào)節(jié)好橡膠輥的壓力。制備硅橡膠輥，江蘇橡膠輥供應(yīng)、拐杖配件時(shí)，要根據(jù)使用條件要求，選取所適合的生膠，配制的橡膠輥外層膠的各項(xiàng)物性還可以進(jìn)一步由多種補(bǔ)強(qiáng)劑和增塑劑等來(lái)調(diào)節(jié)。下面對(duì)在橡膠輥上較為常用的幾種橡膠的特性及其在橡膠輥上應(yīng)用情況分別加以介紹。1.氯丁橡膠：適用于制各軟質(zhì)印刷橡膠輥、照相凹板印刷橡膠輥等。橡膠輥成型可用模壓、膠片包卷成型，纏繞成型或壓出成型等方法。由于膠料的貯存穩(wěn)定性差，因此在制造工藝中，應(yīng)注意避免在直射陽(yáng)光下停放．同時(shí)要控制膠料停放的溫度條件；2.丁腈橡膠：用于制造印刷橡膠輥，江蘇橡膠輥供應(yīng)、食品工業(yè)橡膠輥、紡織印染橡膠輥、接觸溶劑的軟橡膠輥等。丁腈橡膠的耐臭氧性差，因此加工中應(yīng)避免在高臭氧濃度的環(huán)境下操作。丁腈橡膠與聚氯乙烯并用，可得到具有較好的耐臭氧及耐候性的膠料；3.聚氨酯橡膠：具有突出的拉伸強(qiáng)度、耐磨性和抗裂口特性，聚酯型聚氨酯橡膠具有對(duì)多種溶劑的良好的抗耐性。此外，膠料持續(xù)處于高溫和潮濕的環(huán)境之下，江蘇橡膠輥供應(yīng)，也會(huì)對(duì)性能造成不利的影響。用于高速、高壓下的聚氨酯橡膠輥，重點(diǎn)要改進(jìn)動(dòng)態(tài)脫輥問(wèn)題及裂紋現(xiàn)象；4.硅橡膠：耐熱性達(dá)200-250度。膠輥上的軸承的保養(yǎng)在機(jī)器的高速運(yùn)轉(zhuǎn)中。江蘇橡膠輥供應(yīng)</p><div

與丁腈橡膠輥相比，天然橡膠輥的應(yīng)用范圍相對(duì)較小，但還是有很多場(chǎng)合必須使用天然橡膠輥；天然橡膠價(jià)格高，曾一度飆升至40000元/噸，目前天然膠市場(chǎng)價(jià)格也在10000元/噸以上，因此很多天然橡膠輥生產(chǎn)企業(yè)都希望尋找一種天然橡膠的替代原料，達(dá)到降低生產(chǎn)成本的目的。一、天然橡膠輥的替代原料—乳膠再生膠乳膠再生膠是天然橡膠制品廠家常用的降低橡膠制品成本的新型原材料，在天然橡膠輥生產(chǎn)過(guò)程中，選擇高含膠量的乳膠再生膠可以替代更多組分的天然膠，并保證膠輥良好的使用性能和使用壽命；常見(jiàn)的乳膠再生膠有黑白兩種顏色，其中同指標(biāo)的黑乳膠再生膠產(chǎn)品價(jià)格比白乳膠再生膠低，用于生產(chǎn)黑色或深色天然橡膠輥可以降低更多的生產(chǎn)成本；在實(shí)際生產(chǎn)中，乳膠再生膠替代量可以根據(jù)天然橡膠輥的各項(xiàng)指標(biāo)需求決定。二、天然橡膠輥的替代原料—輪胎再生膠輪胎再生膠是廢舊輪胎加工而成的再生膠產(chǎn)品，其原料來(lái)源廣、產(chǎn)品價(jià)格低，深受橡膠制品廠家青睞，由于輪胎再生膠自身性能和膠料相容性的一些限制，并不是所有橡膠制品都可以使用輪胎再生膠。輪胎再生膠主要成分包括天然膠、丁苯膠或順丁橡膠，與天然膠相容性良好，理論上可以摻用在以天然膠為主要原料的橡膠輥中。江蘇橡膠輥供應(yīng)我們建議，在日常情況下，比較好每周都對(duì)使用的橡膠輥?zhàn)鞒鲆欢ǖ木S護(hù)。</p><div

在膠印過(guò)程中，膠輥表面由于帶墨、摩擦、紙毛、紙粉，干燥劑等影響,日積月累下通常會(huì)產(chǎn)生紙屑堆積殘留、油墨、表面硬化發(fā)亮等現(xiàn)象，勢(shì)必會(huì)對(duì)印刷勻墨、油墨移轉(zhuǎn)、印刷質(zhì)量，網(wǎng)點(diǎn)擴(kuò)大率造成直接影響。墨輥是供墨系統(tǒng)的主體，我們必須重視墨輥表面發(fā)亮釉化帶來(lái)的影響，同時(shí)探討并預(yù)防，維護(hù)和解決的方法。（墨輥表面釉化發(fā)亮破損）膠輥表面硬化/釉化的危害①墨輥系統(tǒng)在高速印刷時(shí),由于墨輥硬化,容易產(chǎn)生摩擦高溫,造成供墨不穩(wěn)定②墨輥表面硬化/發(fā)亮,直接影響墨輥的帶墨量與儲(chǔ)墨量,引生實(shí)地供墨不足,印刷前深后淺等問(wèn)題③膠輥表面硬化/發(fā)亮,印刷中容易引生墨杠/水杠及磨損印版防止膠輥表面硬化/釉化發(fā)亮的方法①必須非常關(guān)注墨輥壓力的調(diào)整,膠輥很快硬化/發(fā)亮損壞主要的原因就是來(lái)自超額的壓力。②對(duì)于有速度差的墨輥與水輥(特別是有差速刮墨皮裝置的靠版水輥),要特別關(guān)注正確壓力的調(diào)節(jié),壓力過(guò)大,一定導(dǎo)致膠輥快速發(fā)亮釉化(360度摩擦)。③清洗墨輥,必須使用良好正確的洗車(chē)水,同時(shí)洗車(chē)過(guò)程中,必須多次淋入適量清水,洗出墨輥表面殘留的紙粉/紙毛與膠質(zhì)。④建議每?jī)芍?要用墨輥清潔膏或深層除鈣劑,以涂布并停留較長(zhǎng)時(shí)間的方式,徹底潔凈墨輥表面。⑤關(guān)注工廠水質(zhì)變化。</p><p> 軟化劑用量相當(dāng)于生膠的1~2倍，但會(huì)給混煉工藝造成困難，容易出現(xiàn)遷移現(xiàn)象，可以使用大量油膏填充，以保證半成品遷性。硫化體系一般硫黃倍，促進(jìn)劑選擇硫化流動(dòng)性好，定型慢的促進(jìn)劑為主。常用促進(jìn)劑M、DM單用，用量一份左右。填料一般為輕質(zhì)碳酸鈣，碳酸鎂為主，用量不宜過(guò)多，約20~30份，其他用氯化鋅填充。②丁腈橡膠配合。丁腈橡膠適用于耐油印刷膠輥。采用合成酯類作為丁腈橡膠的軟化劑，用量不宜過(guò)多，避免造成噴出，可與油膏并用，既可降低硬度，又能保證加工工藝順利進(jìn)行，總用量約為200份左右。硫化體系與天然橡膠配合相同，只是硫黃用量稍低，促進(jìn)劑用量稍高。其他配合與天然橡膠配合相同。3、配方舉例《橡膠制品配方》節(jié)選張玉龍4、PPT膠輥報(bào)告（作者不詳）長(zhǎng)按名片二維碼識(shí)別加李工好友，技術(shù)互動(dòng)：點(diǎn)擊下面藍(lán)色“閱讀原文”，了解本工作室詳細(xì)信息！顯出原來(lái)膠輥的橡膠顏色。</p><div

你知道下面的這些現(xiàn)象是如何產(chǎn)生的嗎？印刷版面有明顯條紋現(xiàn)象，印刷版面產(chǎn)生拖花現(xiàn)象，兩色需要疊印時(shí)很困難，到底是什么原因出現(xiàn)的這些問(wèn)題，是機(jī)器出的故障還是操作不當(dāng)？再說(shuō)一個(gè)我經(jīng)?？吹降默F(xiàn)象，經(jīng)常能看到印刷機(jī)操作人員調(diào)機(jī)，尤其是調(diào)印刷含墨量，印刷實(shí)地色塊還好一點(diǎn)，如果是印細(xì)小的字體或網(wǎng)點(diǎn)，操作人員常用的方法是將膠輥與網(wǎng)紋輥調(diào)至擠壓緊無(wú)法再調(diào)動(dòng)的狀態(tài)。這種方法對(duì)不對(duì)呢？我們處理過(guò)很多膠輥和網(wǎng)紋輥軸頭磨損脫焊斷裂，軸承碎裂的狀況。我們先說(shuō)橡膠輥與網(wǎng)紋輥的接觸壓力。相對(duì)于網(wǎng)紋輥與印版輥筒、印版輥筒與壓印輥筒的壓力來(lái)說(shuō)，由于膠輥的作用是把網(wǎng)紋輥表面的油墨擠掉，因此其壓力可以略大些。如果使用的網(wǎng)紋輥線數(shù)偏高，在印刷色塊和大的文字時(shí)，墨量不夠，因此操作者常常采用加大橡膠輥與網(wǎng)紋輥間隙的方法來(lái)增加供墨量。這樣的操作方式不能說(shuō)不對(duì)，但是卻失去了網(wǎng)紋輥定量供墨的作用。使用網(wǎng)紋輥一定要有“定量”供墨的概念，不能用間隙來(lái)調(diào)整墨量，有間隙墨量就控制不好，實(shí)地印不平服，會(huì)出現(xiàn)燈芯絨狀條痕；網(wǎng)線版會(huì)產(chǎn)生色差。如果膠輥與網(wǎng)紋輥在正常接觸狀態(tài)下，網(wǎng)紋輥網(wǎng)墻上的油墨仍不能擠掉，則說(shuō)明水墨的粘度過(guò)高，應(yīng)調(diào)整水墨粘度。膠輥硫化：包膠后的膠輥一般需要10－15小時(shí)的硫化時(shí)間。江蘇橡膠輥供應(yīng)</p><p
