Aliphatic polyesters are not used for fiber production, because of their low melting points. 脂肪族聚酯没有用来生产纤维,可能是熔点低的缘故。
In this paper, the relationship between component and melting point of fluorine free mould fluxes was studied by means of regressive orthogonal design. 论文利用二次正交回归的设计方法对无氟保护渣的成分与熔点的关系进行了研究。
Shrinkage occurs in two parts - as metal superheats above the melting point and has losses, causing shrinkage, followed by further shrinkage during solification. 收缩发生在两个过程中,温度高于熔点的金属冷却时产生收缩,随后在凝固过程中进一步收缩。
