Standard Test Method for Flowability and Bearing Area of Chemical-Resistant Polymer Machinery Grouts 耐化学性聚合物机械浆料的流动性和轴承面积的标准试验方法
发布日期: 2018-12-15
1.1 本试验方法涵盖在50 mm[2-in]范围内评估的耐化学性聚合物机械灌浆流动性的测量或25毫米[1英寸]在实验室环境中浇筑厚度。本试验方法提供了上表面板接触面积(承载面积)的评估。这些灌浆通常至少为两种成分配方,可用于灌浆厚度在25至150 mm[1至6 in]之间的安装在正在灌浆的底座或板下方。 1.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值;因此,每个系统应相互独立使用。将两个系统的值合并可能会导致- 符合标准。 1.3 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 耐化学性聚合物机械灌浆用于为机械或设备提供精确支撑。 注2: 将机械或设备或支撑底座或板或其组合定位到所需的精确标高和位置。底座或板通常放置在准备好的基础上,并由临时垫片或支撑螺栓(千斤顶螺钉)支撑。安装模板以容纳可流动灌浆。在周围浇筑水泥浆,使水泥浆能够在设备底座或板的周围和下方流动。水泥浆随后硬化,形成牢固的刚性支撑层,能够承受设备传递给基础的应力。尽管实际的机械底板通常是金属的,并且本试验中的盖板使用丙烯酸玻璃,但使用丙烯酸玻璃盖板的不同灌浆已被证明在实验室条件下用于本试验中所述的比较目的。 5.2 除了所需的水泥浆物理特性外,实现的流动和承载面积是有效安装水泥浆的重要考虑因素。通过该测试方法测量的两个特性是流量和承载面积。 5.3 流动试验模拟了实验室环境中可流动聚合物机械灌浆的典型应用条件。它可用于评估特定灌浆对特定应用的适用性,比较两种或两种以上灌浆的流动性和承载面积,或评估配方变化、温度、混合技术或其他因素对流动性的影响。 5.4 以百分比表示的估计上部灌浆表面接触量可用于比较两个或多个灌浆,或显示温度、配方变化或其他因素对承载面积的影响。 使用视觉引导的有限结果集(请参阅 图1 和 图2 )用于将轴承分类为“高”-大于85 %,” “中-70 至85 %,” 和“低于70” %.”
1.1 This test method covers the measure of flowability of chemical-resistant polymer machinery grouts as evaluated in a 50-mm [2-in.] or 25-mm [1-in.] pour thickness in a laboratory setting. The test method provides for the assessment of upper surface plate contact area (bearing area). These grouts will typically be at least two component formulations that may be used for installations where grout thickness will range from 25 to 150 mm [1 to 6 in.] underneath the base or plates being grouted. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Chemical-resistant polymer machinery grouts are used to provide precision support for machinery or equipment. Note 2: The machinery or equipment or support bases or plates, or combination thereof, are positioned to the precise elevation and location required. The bases or plates are typically placed on prepared foundations and supported on temporary shims or support bolts (jack screws). Forms are installed to contain the flowable grout. The grout is poured around the perimeter in such a manner as to allow the grout to flow around and under the equipment base or plates. The grout subsequently hardens to provide a strong rigid support layer capable of withstanding the stresses transferred by the equipment to the foundation. Although the actual machinery base plate is typically metal and the cover plate in this test uses acrylic glass, different grouts using acrylic glass cover plates has proven useful for comparative purposes as described in this test in laboratory conditions. 5.2 In addition to the required physical properties of the grout, the flow and bearing area achieved are important considerations for effective grout installation. The two characteristics measured by this test method are flow and bearing area. 5.3 The flow test simulates typical application conditions for a flowable polymer machinery grout in a laboratory environment. It may be used to evaluate the suitability of a particular grout for a specific application, to compare the flowability and bearing area of two or more grouts, or to evaluate the effects of formulation changes, temperature, mixing techniques, or other factors on flowability. 5.4 The estimated amount of upper grout surface contact in percent can be used to compare two or more grouts or show the effects of temperature, formulation changes, or other factors on bearing area. A limited set of results using visual guides (see Fig. 1 and Fig. 2 ) is used to classify the bearing as “high”—greater than 85 %,” “medium—70 to 85  %,” and “low—less than 70 %.”
