在沥青油毡、油纸的物理性能指标中,要求做抗拉强度试验。买一台纤维拉力机要花几千元钱,很不合算。我们利用杠杆式水泥抗拉抗析试验机,将原来的抗拉杭折夹具及双杠杆卸下,留下单杠杆,装上自制的油毡抗拉夹具,能做油毡、油纸抗拉强度试验。为了使油毡在夹 In the physical performance index of asphalt linoleum and oil paper, tensile strength test is required. Buying a fiber puller costs a few thousand dollars, which is uneconomical. We used a lever type cement tensile test machine to remove the original tensile clamps and double levers, leaving a single lever, loaded with self-made bat tensile fixtures, which can be used as linoleum and oil paper tensile strength tests. In order to make the felt in the clip
