The Spray Foam Insulation Gun is one of the most crucial components of the machine set in spray polyurethane foam and polyurea applications. After being processed in the polyurethane spray machine, the two-component polyurethane raw ingredients (isocyanate and polyol) are delivered to the machine by transfer pumps and then reach the gun with the aid of a heated hose. The specially constructed mixing chamber of the spray gun mixes and dispenses the raw material that enters it without first mingling with one another. In other words, inside the polyurethane spray machine system, the polyurethane spray gun serves as the location where the combination is created.
Raw ingredients for polyurea and polyurethane interact quite quickly. Even a very little quantity of raw material particles will interact and harden in the spray gun's tiny chambers in a matter of seconds. Spray guns for polyurethane and polyurea/polyurea require constant airflow to avoid clogging since the solidifying raw materials in the spray gun can lead to downtime. In other words, in addition to the two raw material components, an air connection is made to the gun. When the trigger is depressed, the gun cuts the air and activates the mixture. When the trigger is released, the mixing chamber is immediately cleaned with air, preventing the raw materials from interacting.
Due to the nature mentioned above, polyurethane spray guns need cleaning at the end of every job. Chemicals called Dimethylformamide or DMF (CH3)2NC(O)H are generally used to easily clean the solidifications formed by isocyanate, which is a strong adhesive. In order to make the cleaning work easier, support can also be obtained from the Pusmak UC Ultrasonic non-destroying device. The cleaning of the gun is of vital importance in polyurethane spray foam and polyurea applications, as it will directly affect the performance of the machine and the quality of the product to be produced.
There are two types of polyurethane spray guns, SP and SP2, in Pusmak inventory. Both spray guns are designed for the needs of industry professionals. SP2 Spray Gun stands out in the sector with its adjustable spray feature. Both SP and SP2 model spray guns can work in harmony with the machines of all global brands.
