style="text-indent:25px">橡膠一詞來源于印第安語cau-uchu，意為“流淚的樹”。天然橡膠就是由三葉橡膠樹割膠時流出的膠乳經(jīng)凝固、干燥后而制得。1770年，英國化學(xué)家J.普里斯特利發(fā)現(xiàn)橡膠可用來擦去鉛筆字跡，當(dāng)時將這種用途的材料稱為rubber，此詞一直沿用至今。橡膠的分子鏈可以交聯(lián)，交聯(lián)后的橡膠受外力作用發(fā)生變形時，具有迅速復(fù)原的能力，并具有良好的物理力學(xué)性能和化學(xué)穩(wěn)定性。橡膠是橡膠工業(yè)的基本原料，***用于制造輪胎、膠管、膠帶、電纜及其他各種橡膠制品。三葉橡膠樹提供**多的商用橡膠。它在受傷害（如莖部的樹皮被割開）時會分泌出大量含有橡膠乳劑的樹液。</p><p style="text-indent:25px">膠水是連接兩種材料的中間體，多以水劑出現(xiàn)，屬于精細(xì)化工類，種類繁多，主要以粘料、物理形態(tài)、硬化方法和被粘物材質(zhì)來進(jìn)行分類。常見的有瞬間膠（常見的-1203瞬干膠-氰基丙烯酸乙酯強(qiáng)力瞬間接著劑是一種）、環(huán)氧樹脂粘結(jié)類、厭氧膠水、UV膠水（紫外線光固化類）、熱熔膠、壓敏膠、乳膠類等。膠水不是**存在的，它必須涂在二個物體之間才能發(fā)揮粘接作用。膠水中的化學(xué)成分，在水性環(huán)境里。膠水中的高分子體（白膠中的醋酸乙烯是石油衍生物的一種）都是呈圓形粒子，一般粒子的半徑是在0.5～5μm之間。造紙表面施膠劑配方，找微譜！</p><div

style="text-indent:25px">老化因素A）氧：氧在橡膠中同橡膠分子發(fā)生游離基鏈鎖反應(yīng)，分子鏈發(fā)生斷裂或過度交聯(lián)，引起橡膠性能的改變。氧化作用是橡膠老化的重要原因之一。B）臭氧：臭氧的化學(xué)活性比氧高得多，破壞性更大，它同樣是使分子鏈發(fā)生斷裂，但臭氧對橡膠的作用情況隨橡膠變形與否而不同。當(dāng)作用于變形的橡膠（主要是不飽和橡膠）時，出現(xiàn)與應(yīng)力作用方向直的裂紋，即所謂“臭氧龜裂”；作用于變形的橡膠時，*表面生成氧化膜而不龜裂。C）熱：提高溫度可引起橡膠的熱裂解或熱交聯(lián)。但熱的基本作用還是活化作用。提高氧擴(kuò)散速度和活化氧化反應(yīng)，從而加速橡膠氧化反應(yīng)速度，這是普遍存在的一種老化現(xiàn)象－－熱氧老化。D）光：光波越短、能量越大。對橡膠起破壞作用的是能量較高的紫外線。紫外線除了能直接引起橡膠分子鏈的斷裂和交聯(lián)外，橡膠因吸收光能而產(chǎn)生游離基，引發(fā)并加速氧化鏈反應(yīng)過程。經(jīng)外線光起著加熱的作用。光作用其所長另一特點(diǎn)（與熱作用不同）是它主要在橡表面進(jìn)生。含膠率高的試樣，兩面會出現(xiàn)網(wǎng)狀裂紋，即所謂“光外層裂”。橡膠隔離劑配方，找微譜！湖南膠水檢測需要多少錢</p><p
