In the purchase of polyurethane spraying equipment, we must refer to the parameters of the equipment, application scenarios, brand service and other factors, comprehensive consideration, according to the construction of the scene to choose the right brand; pressure, flow and heating system is the core parameters of the spraying equipment, quality and after-sales service is the guarantee of the product, and cost-effective and we can not be bypassed by the choice!

Usually, 150 - 250 bar pressure is enough for spraying polyurethane; if you encounter that kind of thick modified material, you have to choose 250 - 350 bar high pressure model, but also consider our construction scenarios, for the construction of high-rise buildings, we still need to choose a large high pressure model. Otherwise, the material will not be evenly sprayed and mixed well. Flow rate of how much according to the construction of the area and the duration to determine, 1-3 / L per minute is relatively normal, but if the spraying area is relatively large, you need to choose about 5L per minute. For the heating system in cold places is necessary to pay attention to, if the temperature does not meet the requirements, foaming will receive a great impact!

Spraying equipment has developed rapidly for several years, and now there has been uneven, quality is a must consider, the core components to determine how long the equipment can be used, the pump body, seals, motors, these core components must be the brand's security,. Regular manufacturers have to give at least 1 year machine warranty, such as high-pressure pumps, heating modules, these key components, the warranty period can not be less than 2 years, but also to ensure that 48 hours to repair.

Industry leader Graco products are worthy of affirmation, but the high price and let a lot of people shy away from the alternative brands from China came into being, they not only have Graco's quality and safety, more importantly, their prices are cheap, cost-effective super!
