湖南长沙通风管道优质厂

主要用于冶金、建筑等行业，输送烧结矿、焦炭、水泥熟料等高温物料，物料温度不超过800℃，带面温度不超过220℃的条件下使用。 特性：采用三元乙丙橡胶为覆盖层，主要是根据耐热带破损以至丧失输送能力的主要表现和不同的耐热级别。骨架材料采用国内专用的耐高温帆布，独特的配方设计，解决了因乙丙橡胶饱和度高、粘合性差、层间附着力低的关健问题。具有带体轻、寿命长（约2-4倍）、耐热性能好的特点。

Mainly used in metallurgy, construction and other industries, conveying sinter, coke, cement clinker and other high-temperature materials, the material temperature is not more than 800 degrees, the temperature of the belt surface is not more than 220 degrees celsius. Characteristics: three EPDM rubber is used as the covering layer, mainly according to the main performance and the different heat resistance grade of the tropical damage and loss of conveying capacity. The skeleton material adopts the domestic special high temperature resistant canvas, and the unique formula design solves the Guan Jian problem of the high degree of saturation, poor adhesion and low interlayer adhesion of the ethylene propylene rubber. It has the characteristics of light weight, long service life (about 2-4 times) and good heat resistance.

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 the thickness adjustment, in particular need to test samples on the finished product, may not have the required thickness, so it is necessary to adopt various measures will be adjusted to the range of thickness above, adjust thickness under normal circumstances should be carried out in the sample before molding, and remove rubber bonded fabrics, such as isooctane wet the contact surface, to avoid excessive tensile rubber, get rid of the fabric in the process of clamping near the separation point of the rubber, each separation should not be too much, if the use of volatile liquid rubber should be parked for a long time, parking time can make liquid evaporate completely, at least when placed, need to be prepared into thick rubber sheet the thin film should be used when cutting equipment, rotary cutter equipment, this equipment with reference to industrial production by slicing machine, transported by electric or manual disc cutting knife and the movable belt cutting machine, cutting The cutting table is provided with a slow feeding device, will be sent to the rubber cutting line, and control the thickness of the slice, but also the clamping device is provided with a fixed rubber, for cutting operation, washing liquid lubricating tool with diluted glue and glue; standard test were determined according to density, volume wear and mass loss test calculation test the results obtained with said adhesive wear index and standard value;

最后在硬质热塑性橡胶方面再做以简单介绍及其注意事项，其是在橡胶中加入硫磺和其他配合剂，经硫化制造成的一种硬质材料，由于大量硫化剂的作用，使它具有较高的硬度，可将运输带放入夹持器中，仔细地将其调节对称，以便使橡胶皮带在横截面上的拉力分布均匀，用适当的匀速移动夹持器给试样施加拉力直至拉断为止，记下最大拉力，单位为牛顿，在施加负荷时，应注意到标距器在试样上连续的记录测量标距，以便能在拉断瞬间记录所测最的标距。

At the end of a hard thermoplastic rubber to do simple introduction and notes, which is adding sulfur and other additives in rubber, vulcanized by a hard material made of, due to the large number of vulcanizing agent, which has high hardness, can be put into the belt holder, carefully the regulation of symmetry, so that the rubber belt in the cross section of the tension distribution, with the appropriate moving clamp applying tension to the sample until breaking up, write down the maximum force, unit for Newton, in the applied load, should pay attention to the gauge device on the sample continuous recording measuring gauge in order to test, the standard distance in breaking the record instantly.
