Abstract
Disclosed is an apparatus for producing resin tubes, which has a simple structure and enables to efficiently produce a resin tube whose inner surface is subjected to a homogenization treatment. Also disclosed are a method for producing a resin tube, and a method for producing a roller whose roller surface is covered with such a resin tube. Specifically disclosed is an apparatus for producing a resin tube (1) wherein a resin tube (20) is continuously discharged from an extruder (3) into a conductive liquid (76), while introducing a gas into the inside of the resin tube (20) discharged from the extruder (3) and discharging the gas from the inside of the resin tube (20). In addition, the inner surface of the resin tube (20) is subjected to a plasma process in this apparatus by arranging an inner electrode (71) in the resin tube (20) and applying a high-frequency voltage between the liquid (76) and the inner electrode (71) for generating a plasma within the resin tube (20).
Description
Technical field
The present invention relates to make the manufacture method that inner surface has been implemented the pitch tube manufacturing installation of the pitch tube of plasma treatment, process for producing resin tube, has been coated on roller and this roller of periphery with the pitch tube of this method manufacturing, with this pitch tube.
Background technology
For the roller that uses as backer roll, fixing roller etc. in the image processing systems such as duplicator, printer, require according to its purposes, also to require to be difficult for adhering to the composition that contains in the toner sometimes in machinery, heat, chemically stable.As the roller that is used for such use, having proposed outer peripheral face is the roller that the roller main body of rubber system coats with the fluororesin tube of tetrafluoroethene perfluoroalkyl vinyl ether copolymer etc.When the inner peripheral surface of the outer peripheral face of roller main body and pitch tube is used adhesive, therefore the cohesive extreme difference of fluororesin tube and rubber has proposed inner surface enforcement erosion processing, the primary coat processing of fluororesin tube are waited and improve fusible scheme (with reference to patent documentation 1).
In addition, also proposed to place object being treated in the polybag and in this bag, produce plasma and object being treated is implemented the technical scheme (with reference to patent documentation 2) of plasma treatment.
But therefore above-mentioned arbitrary processing method all exists very low this problem of productivity ratio because object being treateds such as fluororesin tube are handled one by one.
On the other hand, proposed when the inboard of the pitch tube of discharging from extrusion forming device imports gas, to be arranged at the scheme (patent documentation 3) that applies high frequency voltage between the interior electrode in the inboard of this pitch tube and the outside and the external electrode and the inner surface of pitch tube is implemented continuously plasma treatment.
Patent documentation 1: the Japan Patent spy opens the 2005-163837 communique
Patent documentation 2: Japanese patent laid-open 6-285365 communique
Patent documentation 3: the Japan Patent spy opens the 2002-337210 communique
The announcement of invention
But the method for record in the patent documentation 3 be owing to can't avoid producing the gap between the outer surface of pitch tube and external electrode, so the problem that also produces plasma, damages the outer surface of pitch tube is arranged between the outer surface of pitch tube and external electrode.When being used as backer roll, fixing roller etc. in image processing systems such as duplicator, printer by the roller of its coating, the damage of this outer surface will cause toner material adhesion etc., thereby undesirable.
In view of above problem, problem of the present invention is to provide to make continuously and does not damage outer surface and implemented the pitch tube manufacturing installation, process for producing resin tube of the pitch tube of plasma treatment at inner surface, be coated on the manufacture method of roller and this roller of periphery with the pitch tube of this method manufacturing, with this pitch tube.
