膠輥的質(zhì)量主要取決于膠料的配方設(shè)計，丁腈橡膠(NBR)仍是目前紡紗膠輥的優(yōu)先膠種。配方的確定需要進(jìn)行大量的試驗(yàn)，其中對性能影響較大的幾種材料可以采用正交法設(shè)計多組方案，再通過機(jī)械性能比較進(jìn)行優(yōu)化，以篩選出理想的配方設(shè)計。 </p> <p> 并條機(jī)膠輥的成型方式一般有三種：直接包膠模壓硫化；膠管擠出一硫化罐硫化成型；鋁襯管膠管套裝成型。第一種成型工藝缺點(diǎn)是效率低、成本高，但比較大優(yōu)點(diǎn)是膠層密實(shí)，膠層與輥芯粘結(jié)牢靠而不會出現(xiàn)脫輥現(xiàn)象，使用壽命長。后兩種制造工藝使用的成型設(shè)備主要為擠出機(jī)和硫化罐，是現(xiàn)在膠輥制造企業(yè)普遍采用的成型工藝。上海軋輥采購哪家好</p><p
