無錫前洲橡膠有限公司某紙機(jī)生產(chǎn)**瓦楞紙,原料為**廢紙,并添加一定比例渣漿(其他生產(chǎn)線制漿排渣),致紙頁中含沙量大,導(dǎo)致壓榨輥的盲孔易磨損、易堵塞,影響壓榨脫水效率,導(dǎo)致出二壓干度不夠,影響紙機(jī)的穩(wěn)定性和輥?zhàn)拥氖褂脡勖?。目前紙機(jī)實(shí)際產(chǎn)能已經(jīng)超出設(shè)計(jì)產(chǎn)能15%,一些主要脫水設(shè)備已經(jīng)無法滿足紙機(jī)增產(chǎn)要求,尤其是壓榨部,車速提升至800m/min后,紙頁出壓榨部干度偏低,導(dǎo)致干燥部蒸汽用量增加,成本增加。綜合以上因素,通過與設(shè)備供應(yīng)廠家的交流以及新技術(shù)新設(shè)備的應(yīng)用,決定改為聚氨酯包膠,壓榨輥改為盲孔加溝紋。聚氨酯材料耐磨性能好,盲孔溝紋形式包膠增大了壓榨輥的融水空間和甩水效率,有利于提高紙幅出二壓干度,增加紙機(jī)的穩(wěn)定性。通過改造前后對(duì)比發(fā)現(xiàn),紙頁出壓榨部干度提升,壓榨部運(yùn)行負(fù)載降低,紙機(jī)運(yùn)行效率提升,為下一步提速增產(chǎn)提供了保證。包膠輥參數(shù)對(duì)比改造前紙機(jī)一壓壓榨輥為橡膠包膠盲孔輥,改造后包膠材質(zhì)為聚氨酯材料,形式為盲孔加溝紋,基本參數(shù)見表1。可知,包膠形式改為聚氨酯材質(zhì)后,在原來盲孔的基礎(chǔ)上,增加溝紋形式,這樣開孔率由，江蘇**聚氨酯輥筒價(jià)位。開孔率的增加有助于提高紙頁在壓榨部脫水速率,改造后聚氨酯材料耐熱性能突出,延展性能好，江蘇**聚氨酯輥筒價(jià)位,壓榨輥輥筒內(nèi)無需通入冷卻水，江蘇**聚氨酯輥筒價(jià)位。廣泛應(yīng)用于如圓網(wǎng)印花機(jī)、數(shù)碼打印機(jī)，輸送設(shè)備，造紙和包裝機(jī)械等各類傳動(dòng)輸送系統(tǒng)中。江蘇**聚氨酯輥筒價(jià)位</p><div

如國(guó)內(nèi)制造的對(duì)開關(guān)雙色膠印機(jī)，其水輥硬度為23邵A度，傳送墨輥和靠版輥有30邵A度和39邵A度兩種硬度。由于膠版印刷在向著大型、高速、多色卷筒紙輪轉(zhuǎn)機(jī)發(fā)展，并且不斷采用新技術(shù)，如高速熱風(fēng)干燥系統(tǒng)、紫外線感光油黑等，因此，對(duì)膠印膠輥會(huì)不斷地提出新的技術(shù)要求。凸版及膠版印刷用膠輥，是印刷機(jī)傳墨系統(tǒng)中主要的組成部分，它的質(zhì)量對(duì)印刷品質(zhì)量和效率有直接影響。由于膠輥接觸的介質(zhì)（酸、堿、油墨、溶劑）的種類和濃度的不同，以及在印刷過程中所承受的壓力和運(yùn)轉(zhuǎn)速度的差異，對(duì)印刷膠輥的性能要求也是不同的。從膠輥所接觸的油墨的特性來講：對(duì)于酒精基（包括少量的醋酯乙酯）和水基油墨，可采用天然橡膠、氯丁橡膠或乙丙橡膠制備膠輥；對(duì)于使用酯或酮作溶劑的油墨，可采用丁基橡膠或乙丙橡膠制膠輥；對(duì)于烴類溶劑的油墨，需用丁腈橡膠或聚氨酯橡膠制備膠輥；當(dāng)油墨使用甲苯或混合二甲苯以及它們與酯或酮的混合物作溶劑時(shí)，則要求使用聚硫橡膠制膠輥。由于普通油墨多使用烴類作溶劑，因而印刷膠輥一般是由丁腈橡膠或聚氨酯橡膠制備。丁腈橡膠制備的膠輥能抗醇酸樹脂清漆和油墨中的石油溶劑，但由于油能抽出丁腈膠輥中的增塑劑，膠輥在使用過程中易于硬化?；鞜挋C(jī)：用于混煉和切料；油壓機(jī)：用于硅橡膠制品的成型；考箱機(jī)：用于硅橡膠制品的二次硫化。</p><div

我們都知道膠輥的使用范圍非常廣，用途特別多，然而不同用途的膠輥對(duì)橡膠特性的要求也不同。下面就在膠輥上較為常用的幾種橡膠的特性及其在膠輥上應(yīng)用情況分別加以介紹。①氯丁橡膠：是具有較好機(jī)械性能和耐多種化學(xué)藥品能力的優(yōu)良的通用橡膠。適用于制備軟履印刷膠輥、照相凹板印刷膠輥等。膠輥成型可用模壓、膠片包卷成型，纏繞成型或壓出成型各種方法。由于膠料的貯存穩(wěn)定差，因此在制造工藝中，應(yīng)注意避免在直射陽光下停放，同時(shí)要控制膠料停放的溫度條件。②丁腈橡膠：對(duì)烴類油墨、各種礦物、植物油類及多種溶劑具有突出的抗耐性。用于制造印刷膠輥、食品工業(yè)膠輥、紡織印染膠輥、接觸溶劑的軟膠輥等。制輥工藝，除澆鑄法外，其它方法都可采用。丁腈橡膠的耐臭氧性差，且一般用于天然橡膠的抗臭氧劑對(duì)丁腈橡膠的效果都不大，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。用并用膠料制備的紡織膠輥，性能良好，色彩鮮艷，與單用丁腈橡膠相比，成本也有降低。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。江蘇**聚氨酯輥筒價(jià)位</p><p
