A Simple Guide on Various Spray Foam Insulation Equipments
Today, almost every house owner is focused on making their homes more environments friendly and economical. One of the simple ways is to insulate the house properly so that you can control a high volume of energy wastage. The traditional method of fiberglass insulation has been outdated and other types of insulation have been found to be more efficient that the older method. One of them is Spray foam insulation, where two liquid chemicals are mixed together to create a foam as a result of the chemical reaction.
Spray foam insulation is generally applied using specialized equipment which needs to be handled only by trained, experience and professional teams. The equipment may be a plural component proportioning equipment, prepackaged cans or large pressurized bottles. The liquid chemicals are usually stored separately in fifty five gallon drum sets, and when ready to use, they are transformed to the specific equipment with the help of transfer pumps. The chemicals come together only in the spray gun, where they gets mixed to create the foams.
When purchasing the proportioning machines, various factors need to be considered such as, the type of the drive system, pressure and the output capacity, electrical system and the heating capacity of the machines, as these factors can directly affect the minimum and maximum lengths of the hoses to be used. The drive system helps the pumps to move in all four directions, while the metering pump controls the proportion of the materials to come out of the spray gun.
Even though pneumatically driven systems are available at lower costs, good companies prefer hydraulically driven systems due to its high performance. The technology of impingement-mixing is commonly used for mixing the chemicals in almost all the spray guns. Once the two chemicals come in contact with each other, the chemical reaction occurs on the spot and the resultant foam will come out of the spray gun. This foam will get hardened within ten to fifteen seconds and all the materials should be used from the gun as soon as it is ready.
If not, the material will get solidified in the gun and it will become useless. The process which prevents this action inside the spray gun is termed as ‘purging’. There are mainly three types of purge systems that is used in the spray guns namely, air purge, mechanical purge and solvent purge. When applying the spray foam insulation to the roofs, it is not possible to lift the machine along with its auxiliary parts to the roof and that is where the hoses are used.
For the proper processing, the spray foam needs to be heated to a temperature between 140 degrees to 150 degrees Fahrenheit, which is done by the pre-heaters in the proportioning machine. When applying the spray foam insulation to the roofs, these chemicals are delivered to the spray gun using a heated hose, which has the capability to maintain the liquid chemicals at the right temperature till they come into contact for the chemical reaction. All these can be handled with ease by professional contractors who are well experienced in this field.
