| 据了解，固化剂又为名硬化剂、熟化剂或变定剂等，也是一类增进或控制固化反应的物质或混合物。树脂固化是经过缩合、闭环、加成或催化等化学反应，使热固性树脂发生不可逆的变化过程，固化是通过添加固化(交联)剂来完成的。 It is understood that curing agent, also known as hardener, curing agent or modifier, is also a kind of material or mixture to enhance or control the curing reaction. Resin curing is a process of irreversible change of thermosetting resin through condensation, closed-loop, addition or catalysis. The curing is accomplished by adding curing (crosslinking) agent. 固化剂按用途可分为常温固化剂和加热固化剂。 Curing agent can be divided into normal temperature curing agent and heating curing agent. 环氧树脂高温固化时一般性能优良，但是在土木建筑中使用的涂料和粘接剂等由于加热困难，需要常温固化、中温固化剂和高温固化剂，要以被着体的耐热性以及固化物的耐热性、粘接性和耐药品性等为基准来选择。选择重点为多胺和酸酐。由于酸酐固化物具有优良的电性能，所以广泛用于电子、电器方面。 Epoxy resin curing at high temperature generally has good performance, but the coatings and adhesives used in civil buildings due to heating difficulties, need room temperature curing, medium temperature curing agent and high temperature curing agent, to be the heat resistance of the quilt and cured heat resistance, adhesion and drug resistance of the benchmark to choose. The selection focuses on Polyamine and anhydride. Because of their excellent electrical properties, the anhydride cured compounds are widely used in electronics and electrical appliances. 脂肪族多胺固化物粘接性以及耐碱、耐水性均优良。芳香族多胺在耐药品性方面也是优良的。由于氨基的氮元素与金属形成氢键，因而具有优良的防锈效果。胺质量浓度愈高，防锈效果愈好。 Aliphatic polyamine cured products are excellent in adhesion, alkali resistance and water resistance. Aromatic polyamines are also excellent in drug resistance. Due to the formation of hydrogen bonds between the nitrogen elements of the amino group and the metal, it has excellent antirust effect. The higher the mass concentration of amine, the better the antirust effect. 只有对这些原料、技术进行精确把握，并谨慎对其质量进行控制才能生产出高品质的固化剂。 Only by accurately grasping these raw materials and technologies and carefully controlling their quality can high quality curing agents be produced. |
