Description
Technical field
The invention belongs to polyurethane product process units fields, and in particular to a kind of polyurethane laminboard tinuous production use
Fixed cloth lever apparatus and application thereof.
Background technique
Compared with other building heat preservation organic materials, polyurethane foam best, resistance to compression, tensile strength with energy-saving effect
Greatly, the advantages that heat-resistant stability is good.In building energy conservation increasingly by today of extensive concern, especially it is basic to become China for low-carbon energy-saving
After state basic policy, polyurethane foam is in building heat preservation industry by large-scale popularization application.
Continuity method production polyurethane building battenboard is presently the most economic production method, obtained compared with intermittent
Foam is compared, with uniform foam cell is fine and smooth, plate face is smooth, performance is easily controllable and stabilization, high production efficiency, easy for installation etc. are excellent
Point has been widely used for building exterior wall heat preserving field at present.
For polyurethane foam continuous lines production technology, the quality of urethane raw cloth directly affects the object of foam
The presentation quality of rationality energy and battenboard.Domestic manufacturer mostly uses the form for swinging cloth at present, i.e., gets on a straight tube
Several apertures directly swing back and forth discharging with a plastic tube to realize continuous cloth.The shortcomings that the method, is, in the middle part of plate face
Material is easy overlapping, and plate face edge material is relatively fewer, causes entire plate face foam density distribution very uneven, is easy to appear
Weld marks, it is easy to appear plate face shrinkage phenomenons when serious.
Chinese patent CN104842485A discloses a kind of fixed polyurethane boom, which includes a charging
Pipe and a distribution cavity closed at both ends, wherein distribution cavity is equipped with several cloth holes.The key problem in technology point of the invention is to pass through
Change the aperture of nozzle to achieve the effect that stable cloth.Its aperture is gradually decreased from center to two sides, to guarantee that each hole goes out
The material pressure come is not much different.In actual use, combined polyether glycol and polyisocyanate pass through boom upon mixing
Process can chemically react, mixed liquor viscosity gradually increases, the design that depending nozzle aperture gradually becomes smaller, it is easy to
There is the phenomenon that stifled nozzle.When boom is longer, the aperture design of edge can be smaller, is easier to that hole plug occurs.In addition to this,
In practical application, since the hole flow closer to avris is smaller, easily because corner density unevenness occurs in cloth deficiency or lacks material
Phenomenon.
Chinese patent CN 106426721A discloses a kind of polyurethane boom, and key point of the invention is to pass through change
The length of nozzle achievees the effect that stable cloth.In the patent, the length of more second material outlet pipes is from close to first material
Gradually successively decrease toward close to the first plug side outlet pipe side.In practical application, only changing discharging length of tube, intermediate spray will lead to
Mouth and the length difference of edge are very big, if production site operation width is very big, intermediate noxzzle length is up to 5cm or more, this is to existing
Boom position, which is fixed and operated, all to have a significant impact, along with combined polyether glycol and polyisocyanate pass through in mixing
Mixed liquor viscosity gradually increases after bar, and when nozzle longer by length, clogging meeting is it is obvious that be difficult to reach theoretical
On cloth effect.
Summary of the invention
For existing polyurethane laminboard tinuous production deficiency existing for cloth bar assembly, it is an object of the invention to
It provides and a kind of designs more reasonable fixation cloth lever apparatus.
