1.A kind of thermosets with high strength and high modulus was prepared by scrap rubber powder.
利用廢膠粉制備出一種高強(qiáng)度、高模量熱固性塑料。
3.Thermoplastics can be shaped and reshaped by heat and pressure but thermosets cannot be reshaped because they undergo chemical changes as they harden.
熱塑塑料可通過(guò)加熱和加壓成形和再成形,而熱固塑料卻由于在硬化過(guò)程中發(fā)生了化學(xué)變化而不能再成形。
4.In this paper, the advances in chemorheological modeling of reactive processing for thermoplastics and thermosets were reviewed.
綜述了近年來(lái)熱固、熱塑性聚合物反應(yīng)加工過(guò)程中的化學(xué)流變學(xué)模擬進(jìn)展。
5.For thermosets, it is not enough for us to have only chemical criterion and we must upbuild the cure index.
對(duì)于熱固性樹脂,單單有化學(xué)標(biāo)準(zhǔn)是不夠的,必需建立它們的固化指標(biāo)。
