/ a:

Water stop being embedded in the concrete joints, acts as a continuous watertight diaphragm to prevent any seepage of liquids in constructions joints which are subject to hydrostatic pressure. It is designed for expansion or contraction joint; At the same time, it can accommodate lateral and transverse movements which make it capable to suit the moving joints.

\ n \ n II \ n Q: Quelles sont les caractéristiques de l'arrêt d'eau en pvc? \ n A: Voici les caractéristiques de l'arrêt d'eau en pvc:

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.

\ n \ n \ n III \ n Q: Quelle est la méthode de soudage et la méthode de chevauchement de waterstop pvc? \ n A: Ce qui suit sont la méthode de soudage et la méthode de chevauchement de waterstop pvc:

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.

\ n \ n \ n \ n IV \ n Q: S'il vous plaît décrire sur les tests de qualité de l'articulation après le soudage. \ n A: \ n La nervure saillante de soudure était brillante et pleine affaissement vide, pas de scories de soudure de fuite, pas de bulle. bande pliée à 180 degrés avec les mains et les joints de soudure autant que possible dans les coins pointus. Il n'y aura pas de fissure, pas de bulle et pas de traces de laitier. S'il y a des défauts, fusion avec soudage au chalumeau ou coupage au chalumeau \ n \ n \ n \ n \ n \ n \ n \ n V \ n Q: Pouvez-vous me dire les propriétés de l'arrêt d'eau pvc? \ N A: Ce qui suit sont les propriétés de l'arrêt d'eau en PVC;

\ n \ n \ n \ n \ n VI \ n Q: Quelles sont les questions de construction qui nécessitent l'attention de l'arrêt d'eau en PVC? \ n R: Les points suivants nécessitent une attention particulière:

1.In the course of construction,when operating,pay attention to avoid mechanical damage to the sealing belt,because there are many sharp stones and reinforced concrete.

2.When the location of the plastic water stop,the water stop should fit the interface of the concrete flat.There is no turning,no warping about the pvc water stop.Otherwise it should be carried out in a timely manner.

3.When pouring fixed sealing strip,We should prevent the water stop deviation,so as not to affect the sealing effect.

4.Use of bonding, thermal welding, etc. to ensure the plastic water stop joint firm,

5.In the process of pouring concrete,pay attention to adequate shock,to ensure the sealing strips and concrete combine.
