PVC water stop

The quality of PVC plastic stop hose is the key to resist hydraulic pressure and adapt to the deformation of joints.The water stop is a heat-sensitive plastic, which must be heated at the time of fusion. It is necessary to melt the plastic without burning the material or producing air bubbles.The infrared welding device developed by our factory is of small size, light weight, easy to carry and easy to operate, and the strength of the joints after fusion is high, and the strength of its strength is above 92% of the parent material.The specific fusion method is as follows:

1. Fusion method of PVC plastic check belt:

At the end of the welding, the ends of the plastic stop shall be cut and flat, and no holes shall be allowed.And remove dirt.

Insert the connector plug into the power supply for about 15 minutes.

Place the plastic water stop in the fixture or opposite each side of the plastic stop hose and place one end on both sides of the welder to bake at about 15 to 20 mm.

(4) over the entire cross section observation on both ends of the plastic water-stop melting conditions change, attention must not make the color yellow or blister, if discover the situation should be removed to revise and bake, to be baked at both ends of the plastic melt grease to achieve uniform, immediately remove the fusion splicer, closed clamp or two people will quickly end to align the strength of extrusion, the tapping of melting plastic extrusion bulge, the fold in sew out a 3 ~ 5 mm thick, high reinforcement, and lasts for 5 minutes after being cooled to release pressure.

2. Quality inspection after fusion:

The welded seam is bright and full without cavity, no leakage welding, no bubble slag.Will stop after cooling hose with hands folded in half 180 °, the weld joint as much as possible into sharp corners, no crack, bubble and the trace of slag, sensory test without defect.If any defect is found, rewelding or rewelding shall be done with welder.
