exotherm

基本解釋

The curing exotherm of vinyl unsaturated polyester and the factors affecting on it were discussed.
本文討論了乙烯基不飽和聚酯樹脂的固化放熱情況及其影響因素。
These thicker laminates are more difficult to infuse and the exotherm development of traditional epoxy systems can lead to exotherm wrinkles in spar caps.
但這些較厚的層壓板不易進(jìn)行灌注，同時，由于傳統(tǒng)環(huán)氧系統(tǒng)的固化放熱還會導(dǎo)致在主梁生產(chǎn)過程中產(chǎn)生起皺等品質(zhì)缺陷。
The results indicate that:1)Compared with traditional cure agent-ammonium chloride, LUF resins catalyzed by ammonium persulphate have lower temperatures of exotherm, revealing much faster curing rate;
實(shí)驗(yàn)結(jié)果表明：1）與傳統(tǒng)的氯化銨固化劑相比，過硫酸銨催化的脲醛樹脂的熱分析曲線的起始溫度和峰頂溫度都很低，顯示出良好的固化促進(jìn)作用；
