Abstract

The invention provides a detecting device for use in drawing the temperature control phase diagram of the nano latex. It relates to a device for detecting the phase state of nano latex and acquire the phase diagram of the nanometre latex, especially, to a phase diagram detecting device with an adjustable operating temperature. The device consists of polarizing box, electronic constant temperature hydropot, a control unit. The draining pipe of the temperature control water pipe of the sample pipe is connected the water inlet of the electronic constant tempreture hydropot. The inducing pipe of the temperature controlling pipe is connected with the outlet of the electronic constant temperature hydropot. The temperature of the sample pipe is controlled by the electronic constant temperature. The control part is connected with the control unit. The temperature is controlled precisely by the nano latex temperature control phase diagram detecting device when detecting the phase diagram to fulfil to the test requirements. The system can be mixed fully with the mixer, so as to get favourable to the judgment of the phase state breaking point. The operation is simple by adopting closed olarizing box, and can judge the liquid crystal accurately.

Description

technical field [0001] The invention relates to a device for detecting the phase state of the nanoemulsion and then obtaining the phase diagram of the nanoemulsion, in particular to a phase diagram detection device with adjustable operating temperature. Background technique [0002] Nanoemulsion, also known as microemulsion, is a thermodynamically stable oil-water-surfactant-cosurfactant homogeneous system, and the size of its dispersed phase is in the nanometer range. [0003] Since Hoar and Schulman discovered this homogeneous system in 1943 and officially named it microemulsion (microemulsion) in 1959. Both the theoretical and applied studies of microemulsions have made great progress, making microemulsions an important and active branch of interface science. In the 1970s when the oil crisis occurred, the microemulsion system ushered in the climax of its development due to its great potential in EOR technology. [0004] Since the 1980s, espec...
