呋喃树脂主要是由糠醛、糠酮或糠醇经缩合而成的并含有大量呋喃环的合成树脂。它在常温下为粘稠状的棕黑色液体。加入酸性物质可以使它在较短的时间内(一般为几小时到一天)交联凝固,成为一种结构材料。由于呋喃树脂固化后的交联密度很大,且易降解基团又少,所以它的耐蚀性极好,有人认为它仅次于聚四氟乙烯。除了强氧化性介质外,它几乎可耐各种浓度的酸、碱、
Furan resin is mainly composed of furfural, furfuryl alcohol or furfural alcohol condensation and contains a large number of furan ring synthetic resin. It is a viscous brownish-black liquid at room temperature. Adding acidic substances can make it crosslink and solidify in a short period of time (usually several hours to one day) and become a kind of structural material. Due to the high cross-linking density of furan resin cured, and the easy degradation of small groups, so its excellent corrosion resistance, some people think it is second only to polytetrafluoroethylene. In addition to strong oxidizing medium, it is almost resistant to various concentrations of acids, bases,
