热塑性塑料通常分为两类:即结晶质的和非结晶质的。
Thermoplastics are generally divided into two classes: namely crystalline and amorphous.
结晶度:聚合物可以是晶体状的或非结晶质的,但它们通常是晶体状和非结晶质结构的结合物(半晶体)。
Crystallinity. Polymers can be crystalline or amorphous, but they usually have a combination of crystalline and amorphous structures (semi-crystalline).
根据各自的结构不同,聚合物可以是亲水的或憎水的(喜欢或讨厌水)、硬的或软的、晶体状的或非结晶质的、易起反应的或不易起反应的。
Depending on the structure the polymer may be hydrophilic or hydrophobic (likes or hates water), stiff or flexible, crystalline or amorphous, reactive or unreactive.
结晶质聚合物通常也比非结晶质聚合物更致密并且具有更好的机械性能。
Crystalline polymers also generally are denser and have better mechanical properties than amorphous polymers.
用于加强的微粒包含了陶瓷和玻璃之类的矿物微粒、铝之类的金属微粒以及包括聚合物和碳黑的非结晶质微粒。
Particles used for reinforcing include ceramics and glasses such as small mineral particles, metal particles such as aluminum, and amorphous materials, including polymers and carbon black.
对于纵向非均质油藏,醇诱导后的盐结晶颗粒能使油流动阻力增大,压力上升,流动转向。
In the vertical heterogeneous reservoir, the alcohol-induced salt grain could elevate the fluid flow resistance, increase the injection pressure and change the flow direction.
