The rubber sealing belt is mainly used for cast-in-place concrete when in construction joints and deformation joints and concrete structure has become one of the basic engineering facilities, such as underground tunnels, culverts, dams, aqueducts, liquid storage structures etc..
The sealing strip is partially or wholly embedded in concrete during the pouring process of concrete,
There are many sharp stones and sharp head reinforced concrete, the tear strength of rubber and plastic tensile and low 3-5 times, once the waterstop punctured or torn, without external force gap will expand, so the waterstop positioning and concrete pouring process, should pay attention to positioning method and pouring in order to avoid pressure, water stop is punctured, affect the sealing effect, the specific considerations are as follows:
1. The water stop belt shall not be exposed to the outside for a long time to prevent rain, and do not touch with the polluting chemicals.
2, in the transport and construction, to prevent mechanical, steel damage, sealing tape.
3 in the construction process, the water stop belt must be reliably fixed to avoid displacement during pouring concrete, and ensure the correct position of the water stop belt in concrete.
4 fixed strip method: the use of additional reinforcement fixation； special fixture fixed； the wire and the fixed template, such as perforation, can only choose the installation area on the strip edge, not to damage other parts.
5 user orders should be based on the engineering structure design drawings, calculate the length of products, have special structure drawings and specifications, try to connect into a whole band in the factory will stop, if necessary in the field of connection, can use electric heating plate vulcanization bonding or cold bonding (rubber waterstop) or welding (plastic waterstop) method.
Harmful irregularity refers to one of the following c h a racteristics, defects damage uniformity, surface damage and smooth contour, such as holes, cracks, local swelling, incision and inclusion of foreign body, conductive crease, voids, and casting marks such as corrugated bump. Harmless irregularity refers to the irregularity of the surface formed in the process of production. The details are as follows:
(1) 5kV, 10kV, 20kV, 25kV, 35kV can be classified according to the voltage grade
(2) according to the color can be divided into: black rubber pad, red pad, green pad
(3) according to the thickness can be divided into: thick 1mm---50mm；
Long 1m----- unlimited
Range of use
Widely used in substations, power plants, power distribution rooms, test roommates, and outdoor live work.
Should be stored in a dry, ventilated environment, away from the heat source, away from the ground and above 20cm of the wall. Avoid contamination by acids, bases and oils. Do not keep out of the sun. Avoid direct sunlight.
