1)橡膠具有高彈性和黏彈性; 2)與鋼鐵材質(zhì)相比，橡膠的彈性變形很大，彈性模量很小; 3)橡膠的沖擊剛度大于動剛度，動剛度又大于靜剛度，有利于減少沖擊變形和動態(tài)變形; 4)應(yīng)力-應(yīng)變曲線為橢圓形滯后線，浙江進(jìn)口工程機(jī)械用橡膠產(chǎn)品廠家供應(yīng)，其面積等于各個震動周期轉(zhuǎn)變?yōu)闊崃康恼衲?阻尼)，可通過配方設(shè)計調(diào)整之; 5)橡膠為不可壓縮性材料(泊松比為0.5); 6)橡膠形狀可以自由選擇，硬度可以通過配方設(shè)計加以調(diào)整，可以滿足不同方向的剛度和強(qiáng)度的要求。浙江進(jìn)口工程機(jī)械用橡膠產(chǎn)品廠家供應(yīng)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">一、基本工藝流程橡膠制品種類繁多，但生產(chǎn)工藝過程卻基本相同。以一般固體橡膠--生膠為原料的橡膠制品的基本工藝過程包括:塑煉、混煉、壓延、壓出、成型、硫化6個基本工序。當(dāng)然，原材料準(zhǔn)備、成品整理、檢驗包裝等基本工序也少不了。橡膠的加工工藝過程主要是解決塑性和彈性性能這個矛盾的過程。通過各種工藝手段，使得彈性的橡膠變成具有塑性的塑煉膠，再加入各種配合劑制成半成品，然后通過硫化使具有塑性的半成品又變成彈性高、物理機(jī)械性能好的橡膠制品。浙江進(jìn)口工程機(jī)械用橡膠產(chǎn)品廠家供應(yīng)</p><div

style="text-indent:25px">三、塑煉生膠富有彈性,缺乏加工時必需的可塑性性能,因此不便于加工。為了提高其可塑性,所以要對生膠進(jìn)行塑煉,這樣在混煉時配合劑就容易均勻分散在生膠中,同時在壓延、成型過程中也有助于提高膠料的滲透性滲入纖維織品內(nèi)和成型流動性。將生膠的長鏈分子降解形成可塑性的過程叫做塑煉。生膠塑煉的方法有機(jī)械塑煉和熱塑煉兩種。機(jī)械塑煉是在不太高的溫度下通過塑煉機(jī)的機(jī)械擠壓和摩擦力的作用使長鏈橡膠分子降解變短由高彈性狀態(tài)轉(zhuǎn)變?yōu)榭伤軤顟B(tài)。熱塑煉是向生膠中通入灼熱的壓縮空氣在熱和氧的作用下使長鏈分子降解變短從而獲得可塑性。 </p><p 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(jìn)劑等加入到由生膠制成的半成品中在硫化罐中進(jìn)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(jī)多硫化物、過氧化物、金屬氧化物等。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(dá)到比較好狀態(tài)和過硫硫化時間超過、性能***下降都使橡膠性能下降。所以生產(chǎn)過程中一定要嚴(yán)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。

style="text-indent:25px">1.橡膠制品成型時，經(jīng)過大壓力壓制，其因彈性體所俱備之內(nèi)聚力無法消除，在成型離模時，往往產(chǎn)生極不穩(wěn)定的收縮(橡膠的收縮率，因膠種不同而有差異) ，必需經(jīng)過一段時間后，才能和緩穩(wěn)定。所以，當(dāng)一橡膠制品設(shè)計之初，不論配方或模具，都需謹(jǐn)慎計算配合，若否，則容易產(chǎn)生制品尺寸不穩(wěn)定，造成制品品質(zhì)低落。 2.橡膠屬熱溶熱固性之彈性體，塑料則屬于熱溶冷固性。橡膠因硫化物種類主體不同，其成型固化的溫度范圍，亦有相當(dāng)?shù)牟罹?，甚至可因氣候改變，室?nèi)溫濕度所影響。因此橡膠制成品的生產(chǎn)條件，需隨時做適度的調(diào)整，若無，則可能產(chǎn)生制品品質(zhì)的差異。浙江進(jìn)口工程機(jī)械用橡膠產(chǎn)品廠家供應(yīng)</p><p
