耐驰热膨胀仪可以精确测量各种材料（如陶瓷、玻璃与建筑材料）在热处理过程中的膨胀、收缩信息。特别是陶瓷材料，在生产过程中粘合剂的烧失、烧结行为及烧结过程中添加剂的影响都可以通过热膨胀仪测得。热膨胀仪还可以用于釉料的研发，例如瓷器在烧制过程中就需要精确掌握釉料的热膨胀匹配。

 

通过测试热膨胀系数与玻璃化转变温度，可以快速便捷地了解玻璃的变化。在很多情况下，确保相互接触的不同玻璃的热膨胀行为相近非常重要，可以避免应力集中与开裂。

 

水分含量和相变都会影响建筑材料的膨胀与收缩行为，例如混凝土的膨胀特性会显著影响建筑的静态稳定性与使用年限。

 

热膨胀仪能够得到样品尺寸的变化信息，如膨胀、收缩和体积变化。几十年来，这种方法广泛应用于工业领域及研究机构。耐驰所有的热膨胀仪都满足各种相关的标准，例如DIN EN 821, DINASTM E831, ASTM E228等。
 

主要技术参数

Dilatometer can accurately measure the expansion ａnd contraction information of various materials (such as ceramics, glass ａnd building materials) during heat treatment.Especially for ceramic materials, the loss ａnd sintering behavior of adhesives in the production process ａnd the influence of additives in the sintering process can be measured by thermal expansion meter.Thermal dilatometer can also be used in the development of glaze, for example, porcelain in the firing process needs to accurately ｍaster the thermal dilatometer glaze matching.

By testing the coefficient of thermal expansion ａnd glass transition temperature, the change of glass can be quickly ａnd easily understood.In many cases, it is important to ensure that the thermal expansion behavior of different glass in contact is similar to avoid stress concentration ａnd cracking.

Both moisture content ａnd phase transition affect the expansion ａnd contraction behavior of building materials. For example, the expansion characteristics of concrete can significantly affect the static stability ａnd service life of buildings.

The thermal dilatometer can obtain the information of sample size change, such as expansion, contraction ａnd volume change.This method has been widely used in industry ａnd research institutions for decades.All NHC thermal expansion instruments meet a variety of relevant international standards, such as DIN EN 821, DINASTM E831, ASTM E228, etc.
