| 耐热输送带物理性能 Physical properties of heat resistant conveyer belt 执行《输送带具有橡胶或塑料覆盖层的普通用途织物芯输送带》标准， 本标准采用了国际标准草案ISO/FDIS14890-1999标准。 The standard for carrying out "conveyer belt for ordinary use of rubber or plastic cover of conveyor belt" is adopted, and the international standard ISO/FDIS14890-1999 standard is adopted in this standard. 产品标准中最新规定了在执行其他橡胶物理试验用标准时，硫化橡胶或热塑性橡胶样品的制备一些方法,以及试验用耐热带试样和制品尺寸的测定,厚度应符合有关试验方法的规定,除非从技术上考虑试验样品必须采用其他厚度,建议所有试验中用特制模压胶片制备的试样均采用下列厚度,2±0.2mm,4±0.2mm为宜,厚度应按GB/T 5723方法进行测量; In the product standard, some methods for the preparation of vulcanized rubber or thermoplastic rubber samples, as well as the measurement of the size of test resistant specimens and products, should be in accordance with the relevant test methods, unless the test samples must be used in other thickness. It is suggested that all specimens prepared by special moulded film in all tests shall be of the following thickness, 2 + 0.2mm, 4 + 0.2mm, and the thickness should be measured by GB/T 5723 method. 在厚度调整方面，在需要试验的样品上特别是成品，可能不具备规定的厚度要求，因此需要采用各种办法将厚度调整到前面所述的范围内，一般情况下厚度调整应在样品成型前进行，除掉与橡胶粘合的织物，例如用异辛烷湿润接触面，为避免橡胶被过度拉伸，除掉织物过程中夹在靠近分离点的橡胶，每次分离不应过多，如果使用挥发性液体则橡胶应停放一段时间，停放时间要足以使液体完全挥发，至少放置，当需要将厚橡胶片制备成薄胶片时，应使用切割设备，旋转刀设备，此设备参照工业生产用切片机，由电动或手动圆盘切割刀及可移动的输送带切割台，切割台上装有慢速供料装置，将橡胶送至切割作业线，并控制切片的厚度，还应设有固定橡胶的夹紧装置，为便于切割操作，刀具需用稀释的洗涤液润滑；分别测定标准胶与试验胶的密度，依据试验结果的计算与表示方法得出磨耗指数及标准胶的体积磨耗量和质量损失值； In terms of thickness adjustment, the thickness of the sample, especially the finished product, which needs to be tested, may not have a specified thickness requirement. Therefore, various methods are needed to adjust the thickness to the preceding range. In general, the thickness adjustment should be done before the sample is formed to remove the fabric bound to the rubber, such as isooctane wetting. Contact surface, in order to avoid the rubber overstretched, remove the rubber in the process of removing the fabric at the point near the separation point. Each separation should not be too much. If the volatile liquid is used, the rubber should be parked for a period of time, and the stopping time is sufficient to make the liquid completely volatile, at least, when the thick rubber sheet is made to thin film, it should be made. Using cutting equipment and rotating knife equipment, this equipment refers to industrial production slicers, with electric or manual disc cutting knives and movable belt cutting tables. The cutting platform is equipped with slow feeding device, the rubber is sent to the cutting line, and the thickness of the slice is controlled, and a fixed rubber clamping device should also be set. In the cutting operation, the tool needs to be lubricated with diluted washing liquid; the density of the standard glue and the test glue is measured respectively. According to the calculation and representation of the test results, the wear index and the volume wear and mass loss value of the standard glue are obtained. |
