<p>FUCHEM系列乙烯基酯樹脂一般為非預(yù)促進(jìn)樹脂，固化系統(tǒng)與通用不飽和樹脂類似，在室溫或90℃以下固化時(shí)，應(yīng)該加入固化劑和促進(jìn)劑，但因根據(jù)成型工藝、作業(yè)溫度、制品厚度、濕度大小等調(diào)整相應(yīng)的加入量，同時(shí)根據(jù)不同的情況選用不同類型的固化系統(tǒng)。(The basic range of FUCHEM VER are unpromoted and required the addition of both accelerators and promoters just like general UPR. The selection criteria of the curing system and amounts depend on the desired gel time, the temperature of both the resin and workshop, the laminate thickness, humidity, impurities and the posting-curing possibilities.))

<p>為常用固化系統(tǒng)，使用時(shí)加速劑、促進(jìn)劑及固化劑必須分別加入，且每加一種時(shí)，都必須充分混合均勻，方可加入第二種，添加順序?yàn)椋杭铀賱龠M(jìn)劑→固化劑。當(dāng)要求膠凝時(shí)間和固化時(shí)間較快或固化薄層制品時(shí)，可以用過氧化乙酰丙 酮（AAP）取代MEKP；另外適量的DMA加入可以獲得良好的固化效果。(This system is frequent used, and it is important to mix these additives into the resin as follows: first the Cobalt Naphthalene(CoNAP) or Cobalt Octoate(CoOCT) or Dimethyl Aniline(DMA) and then Methyl Ethyl Ketone（MEKP）, also thorough mixing is necessary to get optimum results. In case of thick laminating or short gel time required, AAP is a good accelerator instead of MEKP, meanwhile some DMA is recommended to ensure optimum curing.)

Combinations of different peroxides (such as TBPB or DTDTC) are recommended in order to obtain optimum properties and reduce curing time, these are suitable for pultrusion or thermal-molding. And some positive peresters are recommended in speed pultrusion.)

<p>在較厚鋪層結(jié)構(gòu)或平板制作中，要求較低的放熱峰以控制最小的翹曲和防止分層，應(yīng)推薦異丙苯過氧化氫系統(tǒng)（CuHP）系統(tǒng)，該系統(tǒng)也不產(chǎn)生氣泡，在RTM工藝中可推薦使用；若要求放熱峰值低于100℃，推薦使用CuHP和特丁基過氧化氫的混合物；另外錳鹽促進(jìn)劑可產(chǎn)生較低的放熱峰。(In the production of thick laminates or wet-on-wet above 5mm, lower exothermic heat to avoid over-heating is necessary, which in turn could lead to delaminating, increased shrinkage and possible warping, Cume Hydroperoxide (CuHP) is recommended instead of others, on the other hand, CuHP does not create any foaming and specially recommended for RTM applications. When exothermic peak below 100℃ is necessary, Tertiary Butyl Hydroperoxide(TBPO)is maybe employed in combination with CuHP.)

<p>后固化(Post Curing)</B>：
<p></B>
<p>為使FUCHEM高性能樹脂獲得最佳的耐熱性和耐腐蝕性，如接觸食品、強(qiáng)腐蝕性環(huán)境的FRP，后固化是十分必要的。推薦的后固化條件是90~100℃，3~6小時(shí)——對于厚制品和形狀比較復(fù)雜的制品，后固化時(shí)間需要更長。比較低的后固化溫度是沒有效果的，一般可以通過干熱空氣或加熱器進(jìn)行加溫，同時(shí)可以用油布包覆以提高效果。但過高的溫度會(huì)導(dǎo)致脆裂，應(yīng)防止局部過熱。在制品制作完畢后，后固化處理應(yīng)盡快進(jìn)行以提高效率。(The performance of composite can be enhanced by post curing the finished component at elevated temperatures, especially for these used in aggressive environments or for contact with food. For maximum effectiveness, post curing at 90-100℃ should be performed 3-6 hours as soon as possible after the composite has gelled and its exotherm has subsided. For large components, post curing should be practised as soon at the composite structure is completed. This post curing should be done with hot dry air or heater, yet hot spots should be avoided, a good technique for improving heating efficiency is to cover the post curing vessel or laminate with a tarpaulin.)
