When PHE with small particle size (remarked as PHE-S) was used, the impact and tensile strength of PA66/PHE blends were improved by the addition of the PHE, and presented synergistic effect.
This PHE is generally used in the oil and gas industry, in petrochemical and chemical applications, in the automobile and pharmaceuticals industry, as well as in paper manufacturing.
这一般采用板式换热器是在石油和天然气行业,石化和化工应用,在汽车和制药业,以及在纸张生产。
The distribution of the bound residues of PHE and PYE showed an increasing trend in aging process.
菲和芘的结合残留态部分的分布比例在老化过程中也有增加的趋势。
The addition of PHE also reduced the melt temperature of blends, which result from the dilution effect of PHE that reduced the degree of PA66 crystal.
由于PHE的加入起到稀释效应或是使得PA66晶体的完善程度降低,从而使得共混物的熔点降低。
When other conditions are the same, compare to weaker shear force, stronger shear force leads to better mechanical properties, particularly at low PHE content.
Practice has proved that implementing PHE can improve the effect of health education.
实践证明,实行「参与式」健康教育方式可以大大提高健康教育效果。
PHE focuses on developing and advocating effective preventive policies and interventions based on improved scientific understanding of the environmental determinants of human health.
