In the production process of composite material of machinery of model of phenolic aldehyde EPS machinery, because resinous is agglutinant big, the loose sex of fibre glass is good, one manipulator feed in raw material reachs try out of one’s early years automatic and loose level, but manipulator often is adhered form malfunction, and loose tile opportunity passes general stock to throw small cake because of centrifugal force, do not choose loose end.
Composite material of machinery of model of EPS machinery of one part phenolic aldehyde produces, already instead is tall heat quite vacuum is successive and drab, need to add settleclear speech material ^ only inside high frequency box, no longer loose, direct and drab, make directly piece, expect with squeezing an ancient type of banner hoisted on a featherdecked mast beforehand the circumstance leaves factory. The composite material of machinery of model of phenolic aldehyde EPS machinery that loose circumstance leaves factory, before undertaking squeezing model or constrictive moulding, report can be used knead beforehand hold legal system to become knead beforehand hold makings.
Knead beforehand hold makings can make colophony and fibre glass mix further even. Can advance degree of resinous condensation polymerization, clean small fraction volatile. Consequently, knead beforehand hold makings is OK defeat fibre glass inattentive in colophony inhomogenous. When composite material of machinery of model of phenolic aldehyde EPS machinery squeezes model, idea of sticking to mould is more serious. Its reason is machinery of model of phenolic aldehyde EPS machinery have in composite material combination get together personal Xi alcohol shrinks fourth aldehyde. The idea that dismisses short for Shaanxi Province is to be on the mould one silicon of — of agent of besmear drawing of patterns antrum or silicone oil solution. The bases of the volatile in composite material of machinery of model of EPS Machine of volatile phenolic aldehyde is the young member material such as phenol of water, dissociate. Because the mobile sex of volatile compares high polymer colophony too much, volatile content is consequently high. Make the mobile sex of composite material of machinery of model of phenolic aldehyde EPS machinery big also, be helpful for covering the thin wall part with the mould of the spare parts antrum or messier moulding. But mobile sex passes too when, often break out fat of Yu Shu of fiber activity lag, form fiber and resorcinol cloth not all, affect the quality uniformity of composite material of machinery of model of phenolic aldehyde EPS Machine. Volatile content is too small, the mobile sex of composite material of machinery of model of phenolic aldehyde EPS is too poor, the influence is technical, form short to wait, wu of occurrence goods disagreement. The existence of volatile is idea of a kind of physics. The function of mechanical to model of phenolic aldehyde EPS composite material has the effect that showing.
Be necessary to be controlled strictly so. Usually, the volatile content control of composite material of machinery of model of phenolic aldehyde EPS Machine is in 6 ％ of 5 ％ ～ inside model drama. Composite material of machinery of model of phenolic aldehyde EPS reachs its moulding goods, what its color lets time is outspread and ceaseless deepen. It is yellow commonly, along with time color of outspread Xiang Zong transforms, now and then black appears.
