Polyurethane foaming machines have strict requirements on the handling and control of the production process. The mechanical failures, raw materials, molds, preheating temperature and curing time of the selected product directly affect the molding of the product. Mainly elaborated the control points of the foaming process. When purchasing, you should choose a foaming material company, which is the key to producing qualified polymers. Let the manufacturer of Kotai polyurethane foaming machine bring you some overview and requirements of polyurethane foaming machine.
The high-pressure polyurethane foaming machine strictly controls the ratio of the original liquid to the injection liquid and the ratio of black material, polyether and cyclopentane. If the total injection volume remains unchanged, the proportion of black material is too large, the proportion of white material is too large, the proportion of white material is too high, and the proportion of cyclopentane in the polyurethane high-pressure foaming machine is too high. Inhomogeneous proportions of white materials will result in uneven mixing, resulting in foam shrinkage.
If the polyurethane foaming machine is improperly operated, some parts will fail, and simple fault diagnosis and maintenance should be carried out according to the fault location.
If a specific part of the polyurethane foaming machine fails, the monitoring point will send out a message, and the display will flash immediately to indicate the location of the fault. The program will automatically send out corresponding protections according to the fault location, such as stop, partial stop, injection stop, etc., and send out an alarm.
After troubleshooting of the polyurethane foaming machine equipment, we can press the button for troubleshooting, and the failure text displayed before will disappear. If the fault is not resolved, the text will always be displayed.
Of course, when there is a problem with the polyurethane foaming machine, be careful not to press the button easily, but to troubleshoot the polyurethane equipment, and then use it after careful inspection.
