Introduction:

Our company is a high-tech enterprise in Shanghai. Relying on well-known domestic universities and research institutes, ZUI has adopted a wide range of new scientific and technological achievements from experts at home and abroad, focusing on the development of colloidal and interface, powder technology, textile fiber and other performance measurement technology products. The company's products can be widely used in cosmetics, mineral processing, paper making, medical and health, construction materials, environmental protection, marine, chemical, petroleum, spraying, paint and ink, printing and dyeing, textile, integrated optics, liquid crystal displays and other industries. The company’s customer base includes not only domestic universities, research institutes and military enterprises, but also a large number of multinational companies such as 3M, Foxconn, HOYA Optics, AU Optronics, Samsung Electronics, and Philips, as well as Sinopec, PetroChina, and Granville. The listed companies such as Yuanhuahua, Ningxia Dongfang, Lekai Film, Guanhao Technology, and Rainbow Holdings have products that are exported to the United States, Japan, South Korea, Singapore, Malaysia, Thailand, and Hong Kong and Taiwan.

Technical principle:

    The liquid to be measured is placed in a constant temperature sample container. A capillary tube made of Teflon will dip into the liquid at a given immersion depth. The capillary tube is connected to a gas interface and a sensitive pressure sensor during the test. In the process, a gas or inert gas passes through the capillary tube, forming a bubble at the end of the capillary and measuring the pressure of the bubble.

    When the bubble tension tensiometer JBT07 continuously increases the rheology of the gas, the frequency of bubble formation is accelerated and the life time of each bubble is correspondingly reduced. The formation of a bubble takes two seconds at the beginning of the experiment, and ten bubbles per second can be formed at the end of the experiment. When the bubble radius at the end of the capillary is equal to the capillary radius, the bubble pressure reaches a large value of zii. Once the bubble radius exceeds the capillary radius, the bubble pressure is significantly reduced. The large zui pressure to produce bubbles is proportional to the dynamic surface tension. The hydrostatic pressure P is proportional to the immersion depth of the capillary.
