abrasion strength

The coking test was made on coal sample with the same blending ratio and different bulk densities, the relationships between coke abrasion strength, crushing strength, apparent porosity, coke reactivity index, coke strength after reaction and charging bulk density were obtained.

采用同一配煤比和不同的装煤堆密度煤样进行炼焦试验，得出焦炭的耐磨强度、抗碎强度、显气孔率、焦炭的反应性、反应后强度与装煤堆密度的关系。

The tear strength and abrasion resistance of NR/ SBR vulcanizates were improved by joining the reinforcing resin AD-1600, reinforcing resin OD-60 and 10 phr TPI.

通过加入补强树脂AD-1600、补强树脂OD-60和10份TPI均可提高NR/SBR硫化胶的撕裂强度、耐磨耗性。

However, if the yarns are packed too tightly, the fabric will have reduced tearing strength, abrasion resistance and wrinkle recovery.

但是，如果纱线密度过大，织物的撕裂强度、耐磨强度及折皱恢复能力会降低。

The tear strength, abrasion resistance and H pull-out of vulcanizate increased;

硫化胶的撕裂强度、耐磨性及H抽出力有所提高；

The HF coal ash concrete has the features of high tensile strength, high resistance to abrasion and small quantity of cement use.

HF高强耐磨粉煤灰混凝土具有水泥用量低、抗拉强度高、抗冲耐磨性能优质的特点，因此，极少产生裂缝。

The results showed that the reversion was reduced obviously while the elastic and heat build-up of the compound after overcuring were improved, the tear strength and abrasion resistance were enhanced.

结果表明，PK-900可以明显降低硫化返原现象，并改善过硫后胶料的弹性、生热，提高撕裂强度及耐磨性能。
