测定发泡剂的发泡性能是鉴别发泡剂性能优劣和适当控制发泡剂加入量的重要手段之一。目前,我们用一种简易的测定发泡剂发泡性能的方法来控制发泡剂的加入量。生产实践证明是行之有效的。一、测定方法称取一克试料,溶于500毫升水中,用玻璃棒充分搅拌均匀后,取50毫升配制好的溶液装入直径40毫米、容积260毫升的量筒内,再加50毫升水,然后用手来回 Determining the foaming properties of the foaming agent is one of the important means to identify the performance of the foaming agent and to properly control the amount of foaming agent added. At present, we use a simple method of measuring the foaming properties of blowing agents to control the amount of blowing agent added. Production practice proved to be effective. First, the determination method Weigh one gram of sample, dissolved in 500 ml of water, stir with a glass rod, take 50 ml of the prepared solution into a diameter of 40 mm, a volume of 260 ml measuring cylinder, plus 50 ml of water , Then hand back and forth
