's.
3, wide cut, lightweight, Bao Qiang.Since hard polyurethane foam functions simultaneously as structural material, so that overall structure has
Advantage light-weight, span is big, load is high.Compared with other insulating materials, hard polyurethane foam has best thermal insulation properties.
Therefore, relatively thin polyurethane sandwich can meet the pertinent regulations in relation to the building energy consumption limit, allow for building in this way
Using relatively thin plate when making, space is saved.
4, quality is stable, productivity effect is high.Nowadays, in the case where demand is risen sharply, the work of polyurethane laminboard
The production of factory's metaplasia producing line, in addition to facilitating control quality, more it brings good economy and competitiveness.
5, good weatherability, be easily installed.After polyurethane laminboard is prefabricated in factory, building peace can be used directly to
Dress, is not required to additional process, quick construction.And the variation without taking weather into account, it is produced according to plan.
Further, gas outlet is equipped with diffuser.
In diffuser, the gas and changing flow direction and increase of conduit section area makes flow slowing down, this deceleration
Effect converts kinetic energy into pressure energy.To create the nitrogen with high pressure energy, for subsequent use.
The beneficial effects of the utility model are:
1, using double Shell, insulating heat insulating material is filled between shell.Play the role of thermal insulating, avoids heat
Loss.
2, insulating heat insulating material uses polyurethane foams, has high-efficiency insulated, corrosion resistance, wide cut, lightweight, thin wall etc.
Advantage.
3, wooden thermal baffle is set between inner housing on the inside of rear cover, can be not only insulated, but also to be able to achieve driving motor steady
Fixed operation.
