Standard Test Method for Surface wettability and Absorbency of Sheeted Materials Using an Automated Contact Angle Tester润湿性的标准试验方法及使用自动接触角测试仪测定铁皮表面材料吸水性

Introduction简介

The property of a liquid to adhere,or "wet".a sheeted surface.or to be absorbed by that surface ,or both,is important in many aspects of paper manufacturing and converting,as well as in the end-use applications of many converted paper products.液体的属性，坚持，或“湿“。一席状表面，或者被这种表面吸收，或同时反对两者，在制造和转换的许多方面的重要文件，以及在很多人的终端应用加工纸产品。 Example include,but are not limited to,the adhesion of water or other liquid by an absorbent structure(such as an absorbent tissue or wipe);the adhesion of an ink to a polymer film or a coated or uncoated paper(such as a packaging or wrapping material);the adherence of a polymer film or sizing material to a paper substrate in a laminate or coated structure;the adhesion of a pressure(such as a diaper or other composite structure);and the non-wetting or non-absorbency,or both,of a barrier paper.例如包括但不限于由吸水结构（如吸水组织或擦拭）水或其他液体附着;一个油墨附着力聚合物薄膜或涂层或无涂层纸（如包装或包装材料）;一个聚合物薄膜或胶料坚持在一个结构层压或涂层纸基材;的压力（如尿布或其他复合结构）粘附;和非润湿或不吸水，或两者兼而有之，纸的一个障碍。

The wetting or sorptive behavior between a liquid and a particular sheeted substrate is dependent, at least in a part,upon the relationship of the surface energy(tension)of the liquid and surface energy of the substrate.The theoretical relationship of these energies is complex.and the different mathematical models which have been proposed for adhesion,wettability,and sorption are beyond the scope of this test method.but may be found which will be in contact with a substrate of interest.is used to understand or predict in-process or end-use results of a particular printing,adhesion.or sorptive application.

之间的一个特定的席状液体和基材润湿或吸附行为所依赖的，至少在零件后，表面能对这些能量的衬底理论关系液体和表面能（张力）的关系，是复杂的。以及不同的数学模型的建立已粘连，润湿性建议，并吸附超出了该测试方法的范围，但可能会发现这将与基板接触的兴趣，是用来理解和预测进程或特定印刷，附着力，或吸附应用程序的最终使用结果。

Contact angle measurements as described in Test Method D724or Canadian Pulp and Paper Association CPPA F.3H have been used to study and define the printability relationship between an(aqueous)ink and a paper at the water/paper interface.TAPPI T552and Test Method D2578 use a somewhat different,semi-quantitative approach to provide information regarding the energy relationship between a liquid of known surface tension and the test specimen approached zero under the conditions of the test. 在接触角试验方法D724或加拿大纸浆和纸张协会新闻出版署F.3H描述的测量已被用于研究和确定之间的（水）墨，以及在水/文件介面，龙飞T552和纸张印刷适性的测试方法的关系D2578使用有所不同，半定量的方法来提供有关已知之间的液体表面张力和接触试样能源关系下的试验条件为零。

approach to contact angle measurement applicable to a wide range of sheeted materials and liquids where interfacial contact angles range from near zero to neat 180 degrees.The automated procedure shows increased precision and greater ease in use than manual procedures.在这个测试方法介绍的过程是一个示例，完全自动化的方法接触角测量适用于各种铁皮材料和液体界面的接触角在接近零的范围从180度整齐范围广，自动化程序的提高显示精度和更大的轻松比人工程序使用。

1.Scope范围

1.1This test method measures the contact angle of a test liquid in contact with a flat specimen of a film or a paper substrate under specified test conditions.This test method may be used with any liquid of interest which is compatible with the equipment used,particularly with regard to liquid viscosity,tackiness.and vapor pressure(evaporation).This test method may be used with any substrate of interest ,which can be cut to dimensions compatible with the equipment used.这种测试方法措施，一个电影或一个指定的测试条件下，扁试样纸基材在接触液体的接触角的测试，这种测试方法可用于任何利益液体，与使用的设备兼容，尤其是关于液体的粘度，粘，和蒸汽压力（蒸发）。这种测试方法可能与任何利益基板，可切割尺寸与所用设备兼容使用。

1.2For materials which sorb the test liquid under the specified test conditions.the rate of change of the contact angle as a function of time may be significant,and may be determined using procedures described in this test method.It is also possible to evaluate the sorptive of a surface.as the remaining liquid volume on top of the specimen surface is measured as a function of time.其中膨润土吸附材料的存放在指定的测试作为时间函数的可能是很大的接触角的变化率测试工况下的液体，并可能被确定使用这种测试方法在介绍的过程，也可以吸附评估一个表面，因为剩余的试样表面上液体的体积是衡量一个时间的 …… 此处隐藏：37790字，全部文档内容请下载后查看。喜欢就下载吧 ……
