Epoxy resin is able to bear or endure corrode force comes from where

Epoxy resin is anticorrosive material basically is comprised by the following material. It is epoxy resin, point to contain annulus a general designation of the polymer of oxygen radical, basically apply to caustic not quite strong medium, alkali resistance performance is more outstanding also ability general acid (outside dividing hydrofluoric acid) corrode, foreign anticorrosion market is at present right of epoxy resin need dosage to had decreased greatly, main reason depends on be able to bear or endure colophony of not saturated polyester develops corrode colophony field already quickly, and breed is more, home market starts as a result of colophony of not saturated polyester later, because this epoxy resin still is one of main colophony breed of anticorrosion domain. The main characteristic of epoxy resin is bonding strength tall, shrinkage brittleness of low, product big, price is higher, the colophony of normal temperature solidify uses temperature not to exceed 80 ℃ ; 2 be) the solidify agent of epoxy resin, have amine, acid anhydride kind, colophony apperception combines a few great variety such as content, among them amine compound is most commonly used, it can be divided again wait for a few kinds for adipose amine, balmy amine and modified amine, as a result of second 2 amine, benzene 2 amine, benzene 2 armour amine, polyamide, 2 ethylene the noxiousness of the compound such as 3 amine, odour is bigger, because this is progressively by the new-style solidify agent of avirulent, low poison (be like: T31, 590, C20) replace, dose of this kind of solidify is right damp basic level even underwater is OK also solidify, the attention that causes people increasingly so and reputably; 3 it is thinner, be like,the dilute of epoxy resin uses blame active thinner normally: Alcohol, acetone, benzene, toluene, xylene, thinner of active of 2 kinds of blame can mix use, sometimes to reduce the shrinkage of solidify finished product, reduce hole and chap to also use active thinner, aether of aether of aether of butyl of propane of the oxygen that be like annulus, phenyl of annulus oxygen propane, much shrink glycerine; 4 it is plasticizer, flexibilizer, toughness of more fragile, concussion, bending strength and heat-resisting performance are poorer after pure epoxy resin solidify, commonly used plasticizer, flexibilizer will make colophony increases plasticity, improvement tenacity, raise bending strength and concussion toughness; 5 it is inserts, a general designation of scale of powdery makings, fine aggregate, thick aggregate, glass is inserts, the cost that adds proper inserts to be able to drop product, improvement its function, the) of weight of 20 ～ 40%(that is colophony dosage commonly in the dosage of the inserts in glue fluid, make up be bored with the period of the day from 11 pm to 1 am adds a capacity but some more, the 2 ～ that can be colophony dosage commonly 4 times, commonly used pink makings is quartz pink, porcelain pink, in addition still black lead pink, diabase pink, French chalk, micaceous pink waits.
