style="text-indent:25px">六、硫化把塑性橡膠轉(zhuǎn)化為彈性橡膠的過程叫做硫化它是將一定量的硫化劑如硫磺、硫化促進劑等加入到由生膠制成的半成品中在硫化罐中進行在規(guī)定的溫度下加熱、保溫使生膠的線性分子間通過生成"硫橋"而相互交聯(lián)成立體的網(wǎng)狀結(jié)構(gòu)從而使塑性的膠料變成具有高彈性的硫化膠。由于交聯(lián)鍵主要是由硫磺組成所以稱為"硫化"。隨著合成橡膠的迅速發(fā)展現(xiàn)在硫化劑的品種很多除硫磺外還有有機多硫化物、過氧化物，江蘇進口工程機械用橡膠產(chǎn)品廠家供應(yīng)、金屬氧化物等，江蘇進口工程機械用橡膠產(chǎn)品廠家供應(yīng)。因此凡是能使線狀結(jié)構(gòu)的塑性橡膠轉(zhuǎn)化為立體網(wǎng)狀結(jié)構(gòu)的彈性橡膠的工藝過程都叫硫化凡能在橡膠材料中起"搭橋"作用的物質(zhì)都稱為"硫化劑"。硫化后的彈性橡膠叫硫化橡膠又叫軟橡膠俗稱"橡膠"。硫化是橡膠加工的一個**為重要的工藝過程各種橡膠制品必須經(jīng)過硫化來獲得理想的使用性能。未經(jīng)硫化的橡膠在使用上是沒有什么使用價值的,但欠硫硫化程度不夠?硫化時間不夠未能達到比較好狀態(tài)和過硫硫化時間超過，江蘇進口工程機械用橡膠產(chǎn)品廠家供應(yīng)、性能***下降都使橡膠性能下降。所以生產(chǎn)過程中一定要嚴格控制硫化時間?以保證硫化后的橡膠制品具有比較好的使用性能和**長久的使用壽命。江蘇進口工程機械用橡膠產(chǎn)品廠家供應(yīng)</p><div
