Description
Technical field
The present invention relates to PVC production material dehumidifying technology fields, produce more particularly, to a kind of Double-wall PVC bellows
Material dehumidification system clearing apparatus and dehumidification system and dehumanization method.
Background technique
Double-wall PVC bellows production process is that extruder extruded material is divided into inside and outside two layers through mold, and internal layer is through jacket-cooled
But sizing, outer layer are formed by module (air-blowing), specially material enter in molding machine after due to tubing and block combiner molding
Chamber, injecting air inside, between outer layer separates wave crest (outer layer) with internal layer and is adjacent to type chamber cooling and shaping, and eventually forming has
The double-wall corrugated pipe of specific structure.
In forming process, because inside and outside layer is all than relatively thin, especially outer layer will pass through about 200% drawing when injecting air
Deformation is stretched, therefore it has to be ensured that production material is plasticized well in machine barrel and mold, there is enough melt strengths.
Production material used in Double-wall PVC bellows is mostly high filling formulation, is difficult during mixture in material
Moisture content empty, and temporarily store also be easy dampness.Traditional PVC production material dehumidification system, inside machine barrel vacuum degree can only
Control that moisture content in 0.04~0.06MPa, material is higher, and material melt intensity is difficult to meet production requirement, cause tubing at
Occurs the problems such as dragging brokenly, perforating during type.Moreover, residence time is longer (about in a mold because materiel machining temperature is higher
10~40 minutes, specification was bigger, and the time is longer), the higher material of moisture content is easier sticking to mould and decomposition, and mold is caused to corrode.
In addition, traditional PVC production material dehumidification system, it is easy to fluctuate because of material mixing procedure, not being plasticized completely
Powder be extracted on filter screen.In a very short period of time, filter screen can be blocked all, and extruder vent vacuum degree is caused to plunge,
Material moisture content rises sharply, and generates a large amount of waste products.Moreover, traditional structure clears up difficult and time consuming length.Furthermore from cleaning strainer to recovery
During normal, material basically can not be shaped to tubular structure.It needs manually to clear up the clast being scattered on molding machine in time, it is no
It will cause molding equipment damages.
Therefore, must have and develop a kind of applicable production material dehumidification system for Double-wall PVC bellows, to guarantee material
Lasting, stable, effective, the raising Double-wall PVC bellows production qualification of dehumidification process.In addition, the water content in material is reduced,
Help to improve the performances such as ring stiffness, ring flexibility and the impact of Double-wall PVC bellows.
