，必需經(jīng)過一段時(shí)間后，才能和緩穩(wěn)定。所以，當(dāng)一橡膠制品設(shè)計(jì)之初，不論配方或模具，都需謹(jǐn)慎計(jì)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)牟罹啵踔量梢驓夂蚋淖?，室?nèi)溫濕度所影響。因此橡膠制成品的生產(chǎn)條件，需隨時(shí)做適度的調(diào)整，若無，則可能產(chǎn)生制品品質(zhì)的差異。</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(gè)**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(jià)值的,但欠硫硫化程度不夠?硫化時(shí)間不夠未能達(dá)到比較好狀態(tài)和過硫硫化時(shí)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(shí)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。</p><div

style="text-indent:25px">三、塑煉生膠富有彈性,缺乏加工時(shí)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(shí)配合劑就容易均勻分散在生膠中,同時(shí)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(dòng)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。江蘇專業(yè)橡膠產(chǎn)品生產(chǎn)基地</p><p

style="text-indent:25px">四、混煉為了適應(yīng)各種不同的使用條件、獲得各種不同的性能,也為了提高橡膠制品的性能和降低成本必須在生膠中加入不同的配合劑。混煉就是將塑煉后的生膠與配合劑混合、放在煉膠機(jī)中通過機(jī)械拌合作用使配合劑完全、均勻地分散在生膠中的一種過程。混煉是橡膠制品生產(chǎn)過程中的一道重要工序,如果混合不均勻就不能充分發(fā)揮橡膠和配合劑的作用影響產(chǎn)品的使用性能?；鞜捄蟮玫降哪z料人們稱為混煉膠它是制造各種橡膠制品的半成品材料,俗稱膠料通常均作為商品出售購買者可利用膠料直接加工成型、硫化制成所需要的橡膠制品。根據(jù)配方的不同?混煉膠有一系列性能各異的不同牌號和品種?提供選擇。上海優(yōu)良橡膠產(chǎn)品哪家好</p><p
