Q:What are the features of
PVC Water Stop?
A:The following are the features of pvc
Water Stop:
| 1. Rubber waterstop will expand when getting in touch with water, so allowing it to come into closer contact with the concrete, creating a better water-stop result. |
| 2. Different thicknesses structure is adopted for the cross section, which is divided into the high-strength area, the waterproof area and the installation area, allowing for uniform and reasonable stress for all portions. |
| 3. At installation area add installing hole, it could facilitate fixed with adjacent reinforced, and not produce shifting. Construction is convenient, positioning installation is firm. |
| 4.High quality meet even exceed the industrials standard. |
| 5.Never discolor concrete. |
| 6.No electrolytic action with surrounding metals. |
| 7.Capable to withstand hydrostatic pressure. |
| 8.Heat weldable in conjunction with electric splicing irons. |
| 9.Withstand the expansion and contraction movement of the joints. |
| 10.Capable to taking care of any deflection or displacement arising caused by temperature changing or differential settlement of foundation. |
| 11.Supplied in coils for easy handling with high flexibility. |
| 12.Easy to install by tethering the outer flanges of the PVC Waterstop to adjacent a reinforcing bars. |
II
Q:What are the welding method and overlapping method of pvc waterstop?
A:The following are the the welding method and overlapping method of pvc waterstop:
| Weld of pvc waterstop | 1.Before welding,cut the both ends of the weld plastic flat,there shall be no gap. And clean the dirt. |
| 2.The connector plug in the power supply is about fifteen minutes. |
| 3.The plastic waterstop placed in the fixture or two people opposite hold each end of plastic sealing on the welding device on both sides of about 15 - 20 mm bake. |
4.To observe the change of both ends of the plastic waterstop melting of the whole cross section and Note that do not make their color yellow or sparkling.If it is found that this situation should be removed and re modified to bake.When the two ends of the plastic melt grease evenly after baking,take off the fuse immediately and Closure and clamp or two people increase the strength to squeeze on two end immediately.
When the melting plastic bulge at the joint,the closure will bulge a thick seam, about 3-5 mm band,then release pressure after cooling lasts for about 5 minutes. |
| Lap of pvc water stop | 1.Repair both ends of the water stop which will be lapped about the length of 100 mm with knife. |
| 2.With the heating of the flat iron (thickness of 4-5mm, burning red after a slightly placed 10 seconds or so) sandwiched between the bonding surface pressuring and pull the flat iron out slowly. |
| 3.The two section respectively overlapped with heated steel (phi 18) into a certain slope can be. |
III
Q:Please describe about the quality testing of joint after welding.
A:
Weld seam protruding rib was bright and full empty sag, no leakage welding slag, no bubble.
The strip folded 180 degrees with hands and the weld joints as much as possible into sharp corners. There will be no crack,no bubble and no traces of slag. If there are defects, re fusion with welding torch welding or cutting
IV
Q:How about the retention of properties after immersion about the pvc water stop?
A:
| Retention of properties after immersion |
| Water Absorption at 48 hours | 0.50% |
| ASTM D-570-63 |
| Water-soluble material at 24 hours | 0.10% |
| ASTM D-570-63 |
V
Q:How about effect of Alkali (B) about the pvc water stop?
A:
| Effect of Alkali (B) |
| Change in hardness to 7 days & ASTM D -618-61 | ± 5 |
| Change in weight | 0.07 |
