橡胶拉力机测试橡胶的要求
橡胶拉力机测试橡胶的要求
Rubber tension machine requirements for testing rubber
1.大行程。
The 1. big trip.
由于橡胶在拉伸时变形量很大，尤其是乳胶制品，伸长率有可能高达1000%以上。所以在橡胶试样断裂之前，必须保证夹持器有足够的行程。
Because the deformation of rubber is very large when it is stretched, especially for latex products, the elongation of rubber can be as high as 1000%. So before the rubber specimen is broken, it is necessary to ensure that the holder has enough travel.
2.高精度及高频率的数据采集。
2. high precision and high frequency data acquisition.
拉伸橡胶不需要很大的力，拉力测量范围不需要很大，所以需要力值的精度较高。一般要求试验机能够求取小数点后两位以上精度的力值。此外由于检测橡胶拉伸性能需要拉伸过程中的数个拉力值，而拉伸试验又不可重复，所以即时准确记录每个试验段的拉力力值对于试验成败起着非常重要的作用。
Tensile rubber does not require great force, and the measuring range of tension does not need to be large, so the precision of the force is high. The test machine is generally required to be able to obtain the force values of more than two bits after a decimal point. In addition, it is necessary to record the tensile force values of each test segment accurately and accurately, which is very important for the success or failure of test.
3.准确的标距测量和记录装置。
3. accurate distance measurement and recording device.
试样标距的测量是计算橡胶伸长率的重要数据，所以橡胶拉伸试验中拉力试验机必须准确地测量试样的应变量，并即时地记录下来。
The measurement of sample gauge is the important data for calculating rubber elongation. Therefore, the tensile testing machine must accurately measure the strain of the specimen and record it immediately.
4.可以准确描述应力-应变曲线的装置。
4. a device that can accurately describe the stress-strain curve.
拉伸试样中的拉力值和标距之间有着密切的联系，例如：试样的定伸应力需要测量试样拉伸到给定伸长率的力值，而定应力则需要测量试样拉伸到给定应力的标距。试验完成后，准确的应力-应变曲线可以再现试验过程，并清晰的反映每个试验段的数值，便于计算试验要求的项目。
There is a close relationship between the tension value and the gauge distance in tensile samples. For example, the tensile stress of a sample needs to measure the force value of a specimen stretching to a given elongation, while the constant stress needs to measure the standard distance between the specimen stretching to the given stress. After the test is completed, the accurate stress-strain curve can reproduce the test process, and clearly reflect the values of each test section, so as to facilitate the calculation of the items required for the test.
