The difference between pipe and high-end paper tube paper

1, the data of paper cutting: determined thickness symmetry, low moisture content and appearance smooth sand tube as the main body of paper, paper chooses including impregnated paper as the surface layer of paper; Dongguan made according to the size needed for the high-end paper tube, tube to sand paper tube big volume and surface layer of paper roll in cutting and cutting machine development, get the required size of the paper tape;

2, volume tube: glue tape on the roll mill enthusiastically after winding into tube;

3, coarse-textured: dongguan high-end paper tube at a constant speed in the resin coated paper tube through air drying machine, thick paper cut into a certain length of section;

4, fine cut: after extrusion forming of tube according to the size of the required specifications development rough cutting, after cutting and the transverse development of paper tube after chamfering, coating treatment of punishment, packaging, described to complete the manufacture of high-grade paper tube seamless appearance.

5, dry paper tube: the rough cut into long dry section of paper into the chamber, until the paper tube water content lower than 10%;

6, paper tape, glue: how much will be subject of tape and punish the groove treated surface layer of tape in order from top to bottom step by step a dislocation composite rules respectively in parallel into the tape coating machine, on the subject of tape and surface layer of tape looks well-balanced special use glue coating a layer of paper tube;

7, extrusion molding: after the dry section of paper layout after cooling to room temperature, one by one into the has been preheated to 150-150 ℃ temperature inside extrusion molding mold development, in order to make paper tube outer appearance has coating resin were fully curing; Mold molding temperature is 150-280 ℃

8, groove treatment of punishment: the surface of tape on both sides of paper tape in the groove machine development groove disposed of punishment;

9, exterior coating, paper tube for winding molding grinding appearance development after the disposal of punishment, in its appearance symmetry coating thermosetting resin
