②、樹脂的固化度越高其制品的耐腐蝕性越好； </p> <p> ③、樹脂的固化度越高制品耐熱性能越好； </p> <p> ④、拉伸強(qiáng)度和斷裂延伸率的比較大值出現(xiàn)在樹脂固化度為 90%左右。 </p> <p> UPR 的固化是一個復(fù)雜的化學(xué)過程，受很多因素的影響，因此，無論是 UPR 生產(chǎn)廠家，還是應(yīng)用廠家都應(yīng)掌握一些 UPR 基本的固化常識，才能在安全生產(chǎn)、提高生產(chǎn)效率的基礎(chǔ)上，針對自身產(chǎn)品的特點(diǎn)，有效地解決實際生產(chǎn)中出現(xiàn)的各種問題。相信隨著應(yīng)用廠家對樹脂的固化常識的不斷深入了解，他們生產(chǎn)的產(chǎn)品質(zhì)量將會有質(zhì)的飛躍。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> 活性氧含量簡單來說就是過氧化物中氧和過氧化物分子總量的百分比。 </p> <p> 從這個概念本身來說，一個具有較低的分子量的過氧化物的活性氧含量可能相對較高。但這并不意味著活性氧含量高的過氧化物比活性氧含量低的過氧化物具有更多或更快的活性。（因為我們很多應(yīng)用廠家是用活性氧含量作為考核固化劑的一個指標(biāo)）事實上，活性氧含量**是作為一個恒量任何一個特定的過氧化物的濃度和純度的一個尺度。人們發(fā)現(xiàn)許多具有較高的活性氧含量的過氧化物并不適合用于固化樹脂，因為它們在標(biāo)準(zhǔn)的固化溫度下會很快地分解或“耗盡”，也就是它分解游離基的速度過快。由于游離基總是有一種彼此間相互結(jié)合的強(qiáng)烈傾向，當(dāng)游離基產(chǎn)生的速度比它們被不飽和雙鍵利用的速度快時，它們會重新組合或者終止聚合鏈，從而產(chǎn)生低分子量的聚合物而導(dǎo)致不完全固化的結(jié)果。（典型的例子就是過氧化氫）。施工環(huán)境對樹脂的固化影響很大，施工時環(huán)境溫度越高，膠凝和固化時間越短。</p><div

不飽和聚酯樹脂作為復(fù)合材料，在涂料、玻璃鋼、人造石、工藝品等領(lǐng)域，都已經(jīng)得到了較好的應(yīng)用。但不飽和樹脂的顏色黃變，一直是一個困擾生產(chǎn)廠家的問題。通常不飽和樹脂的黃變原因包括以下幾種： </p> <p> 1、不飽和樹脂酯化合成過程中，由于高溫引起的熱老化黃變，不飽和樹脂一般酯化溫度，為180～220℃甚至更高，在此溫度下樹脂很容易因熱老化而變黃，影響樹脂產(chǎn)品外觀； </p> <p> 2、樹脂接觸紫外線而引起的黃變，主要因素是樹脂中存在的苯環(huán)(包括芳香族二元酸/酐和苯乙烯引入的苯環(huán))，原因可能是芳香族化合物在高溫時發(fā)生熱氧降解，容易發(fā)生π→π軌道上的電子躍遷，使樹脂呈現(xiàn)黃色； </p> <p> 3、樹脂生產(chǎn)過程中，因裝置密封性不好等原因使原料接觸氧氣，通用不飽和聚酯分子鏈中不*含有酯基、羥基、羧基，而且含有雙鍵和芳香環(huán)，微量氧能使其發(fā)生熱氧化降解，**明顯的表現(xiàn)就是樹脂顏色變黃。 </p> <p> 4、添加劑的影響如抗氧劑、阻聚劑、固化劑等，胺類抗氧劑易轉(zhuǎn)變成氮氧自由基而使制品著色，常用的阻聚劑，如對苯二酚，在微量氧存在時氧化為醌類，醌類本身帶有顏色，從而影響樹脂的顏色，固化劑有些廠家仍采用過氧化酰類-叔胺體系和過氧化酮類-金屬皂體系，由于叔胺和金屬皂都有顏色，容易使樹脂著色。 </p> <p> <br /> 否則促進(jìn)劑與初級游離基的逆反速度會大于初級游離基引發(fā)單體的速度，結(jié)果使轉(zhuǎn)化率下降。浙江漢高固化劑和促進(jìn)劑</p><p style="text-indent:25px">拉伸強(qiáng)度和斷裂延伸率的比較大值出現(xiàn)在樹脂固化度為 90%左右。江蘇玻璃鋼固化劑價格</p><p> 間氨基甲胺 MAMA （NH2）（CH2NH2）C6H4
