Introduction of Polyurethane Foam
In our daily life, pu foaming machine plays an important role, we are living in many places have polyurethane foaming machine products, but we never pay attention to and understand it, for it produces a lot of misunderstanding, think that it is useless device, in fact, it has gradually integrated into our daily life, so what is the pu products? Let's understand it.
1. Polyurethane foam: With polyurethane as raw material to produce foams, divided into rigid polyurethane foam, semi-rigid polyurethane foam and soft polyurethane foam, rigid polyurethane foam is mainly used for building insulation materials, insulation materials (such as plumbing, insulation, etc.), such as daily necessities buffer material, sofa bed, refrigerator air thermal insulation layer, a surfboard core material, And transportation materials (vehicles, aircraft, railway vehicle liners, ceilings, etc.).
2. Polyurethane foam material: polyurethane fireproof sponge, also known as flame retardant sponge and flame retardant cotton, is generally a variety of polyurethane fireproof material, mainly used in furniture manufacturing, massage equipment manufacturing, baby carriage manufacturing, decoration, auto parts and so on. Polyurethane waterproof materials such as wall sound absorption, insulation pipe, fire door, fire shutter are also polyurethane raw materials, easy to use, on-site mixing coating at room temperature, humidity curing can be obtained without joints, rubber elastic, good performance waterproof layer.
There are many kinds of polyurethane catalysts with different catalytic activities and effects. In the production of polyurethane products, according to the type of raw materials, production methods, product use and performance requirements, reasonable selection of catalyst.
Polyurethane foaming machine is a special foam polyurethane foam casting equipment, as long as the components of polyurethane materials (components of isocyanate and polyether polyols component) performance meet to the requirement of formula, can produce even and qualified foam products, is in the presence of foaming agent, catalyst and emulsifier, with multiple more alcohol and isocyanate polyether esterification reaction foaming and foam.
The appearance of the polyurethane foaming machine is more compact, polyurethane foaming machine must notice when the choose and buy of foaming machine equipment accessories, spare parts good equipment quality should also not too bad, manufacturer of polyurethane foaming machine equipment also has a lot of, but not many big brand, if you don't know how to choose and buy, can directly go to the shop to buy, And the big brand products have good after-sales service, to the later fault maintenance is also guaranteed.
