Minimum Film Forming Temperature Test Machine Description

When emulsion polymer use to produce paint, 粘合剂, 化学混纺织物, 皮革或纸张表面处理剂, 它的成膜性能非常重要. 在金属板上涂上乳液聚合物或乳胶漆, when the water has been evaporated, 聚合物颗粒在适当的温度下由于相互作用而形成连续且透明的薄膜. 该乳液聚合物的临界成膜极限温度称为最低成膜温度, MFT 温度的缩写.

Minimum Film Forming Temperature Test Machine Principle

在合适的金属板上设置冷却源和加热源,并保持恒定温度至设定点. Different temperature grads would appear on this board,because of metal heat conduction. 在该温度梯度板上涂上均匀厚度的样品, 样品的水分在不同温度的加热下会蒸发,样品形成薄膜. 不同温度下成膜性能不同. 找到边界,则其对应的温度就是该样品的MFT温度.

最低成膜温度测试仪多功能时间测试是最新的高精度产品 . We use platinum resistance import from Germany as temperature sensor, 采用模糊控制理论与PID控制相结合的LU-906M智能温度控制器 , ensure it shows an error less than 0.5%±1 bit. In order to reduce size, we use special size grad board at all costs. Furthermore, there is water-break protection system for any water break, the machine will turn off automatically once there is water-break. For saving water consumption, we let tester screen show cooling water temperature (on the 15th 和 16th point of inspection recorder), decrease the water consumption as far as possible(by hand) according to different settings. In order to judge MFT point successfully, we design clear and high graduate scale in the front of the working table.

design with ISO 2115, ASTM D2354 , and can test minimum film temperature of emulsion polymer easily and accurately.
