First, the heating tube is sprayed when the pressure of the gun is about 500-700 psi. Under the decompression of the key index, the proportion of the cylinder piston rod returning to the cylinder can be seen, and the pressure has been returned to stop. Due to the certain pressure in the pipeline, the moisture in the air is not easy to enter the pipeline, ensuring that the raw materials are not affected by the moist air. This material does not deteriorate and crystallize in the tube. This method is very helpful for equipment maintenance in daily use.
Second, the material pump material: After cleaning the surface of the foaming machine with a vacuum cleaner, the host cleaning agent is placed in its sealed protective cover to prevent the feed rate of the isocyanate group from reacting with a small amount of water, and the pumping rate is low.
Third, machine cleaning: If the construction completion interval and the next construction time exceed 30 days, the entire material system must be thoroughly cleaned, sealed and cleaned.
Fourth, foaming machine equipment proportional cylinder: In the normal operation of the equipment should pay attention to the automatic cleaning system of the cylinder, cleaning fluid circulation cleaning fluid circulation is normal, if there is turbidity, crystal phenomenon, if abnormal circulation is required to check the cleaning liquid pipe blockage or inspection Cyclic or turbid liquid circulation crystallization phenomenon; crystallization phenomenon changes.
