The invention discloses an anti-coagulation monitoring method and system in the processing process of low-temperature non-freezing polyurethane glue. Different degrees of heat of the two glue solutions, and then open or close the first automatic valve or the second automatic valve to control the injection of the first solvent or the second solvent, respectively, according to the principle of infrared thermal imaging images to accurately control the two different The viscosity of the slow-release gel can be dissolved in a suitable solvent, thereby improving the appearance of the glue product, reducing the cost of the slow-release solvent, realizing precise anti-coagulation control of the glue processing process, and preventing gel agglomeration The phenomenon leads to processing failure, and the invention is applied to the technical field of resin processing.
Description
technical field [0001] The invention relates to the technical field of processing low-temperature non-freezing polyurethane glue, in particular to an anti-condensation monitoring method and system during the processing of low-temperature non-freezing polyurethane glue. Background technique [0002] During the processing of low-temperature non-freezing polyurethane glue, it is necessary to add polyester polyol, polyether polyol, HDI, XDI, IPDI, pentaerythritol, ethylene glycol, 1.6HD, neopentyl glycol, TMP, organic bismuth catalyst, During the reaction process of the EAC solvent system, its coagulation phenomenon is inevitable, which will cause the problem of local coagulation and dead glue. Therefore, it is necessary to monitor the coagulation phenomenon, and add additives to stir to prevent coagulation. The current stirring is too mechanical, and it is difficult to accurately control the coagulation phenomenon. It can only be continuously stirred and added with EAC solvent ...
