style="text-indent:25px">1 耐介質(zhì)增重實(shí)驗(yàn)可以從成品上取樣，浸泡在選定的一種或幾種介質(zhì)中，一定溫度時(shí)間后取稱重，根據(jù)重量變化率硬度變化率推斷材料的種類。2 熱空氣老化實(shí)驗(yàn)從成品中取樣，放在老化箱里老化***，觀察老化后的現(xiàn)象。可以分級(jí)老化逐步升溫。比如150℃下CR，NR，SBR都會(huì)脆斷，NBR EPDM還有彈性。升到180℃下普通NBR就會(huì)脆斷；而230℃下HNBR也會(huì)脆斷，氟膠和硅膠仍然有很好的彈性。3 燃燒法取少許樣品，在空氣中燒。觀察現(xiàn)象。一般來說氟膠，CR，CSM離火自息，即使燒著火苗也比一般NR、EPDM的要小的多。當(dāng)然，如果仔細(xì)觀察，燃燒狀態(tài)、顏色、氣味也會(huì)提供為我們很多信息。比如NBR/PVC并用膠，有火源時(shí)火劈啪的亂濺，似乎有水似的，離火自熄，煙濃且有酸味。需要注意的是有時(shí)添加了阻燃劑但不含鹵素的膠也會(huì)離火自熄，這要借助別的辦法進(jìn)一步推斷。4測(cè)比重用電子稱或分析天平，精確到0.01克的即可，外加一杯水，一根頭發(fā)絲即可。一般來說氟膠比重比較大，1.8以上，CR ECO的也多在1.3以上比重明顯偏大的可以考慮是這些膠。5 低溫法從成品上取樣，用干冰和酒精制造一個(gè)合適的低溫環(huán)境。把樣品泡在低溫環(huán)境下2-5分鐘，在選定溫度下感覺軟硬程度。江蘇膠水性能改進(jìn)多少錢粘扣帶**膠配方，找微譜！</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">天然橡膠主要來源于三葉橡膠樹，當(dāng)這種橡膠樹的表皮被割開時(shí)，就會(huì)流出乳白色的汁液，稱為膠乳，膠乳經(jīng)凝聚、洗滌、成型、干燥即得天然橡膠。橡膠制品合成橡膠是由人工合成方法而制得的，采用不同的原料（單體）可以合成出不同種類的橡膠。1900年-1910年化學(xué)家C.D.哈里斯(Harris)測(cè)定了天然橡膠的結(jié)構(gòu)是異戊二烯的高聚物，這就為人工合成橡膠開辟了途徑。1910年俄國(guó)化學(xué)家SV列別捷夫(Lebedev，1874-1934)以金屬鈉為引發(fā)劑使1，3－丁二烯聚合成丁鈉橡膠，以后又陸續(xù)出現(xiàn)了許多新的合成橡膠品種，如順丁橡膠、氯丁橡膠、丁苯橡膠等等。合成橡膠的產(chǎn)量已**超過天然橡膠，其中產(chǎn)量比較大的是丁苯橡膠。</p><p
