Flexible square water bladder

According to the nature of the transport liquid to choose what material to make water bags, if used to transport drinking water, sugar and other neutral food grade liquids choose polyether polyurethane material to make water bags; if used for transporting edible oil, gasoline, etc. The oil liquid is made of polyester polyurethane material; if it is used for transporting industrial waters and other neutral non-food grade liquids, PVC material must be selected.

Three-dimensional square soft water bladder features

1. Water resistance: that is, after the action of water and infiltration by water, the properties of the crucible are basically unchanged, and it is impervious to water under the pressure of water.

2. Temperature stability: no flow, no blistering, no sliding at high temperatures; no brittleness at low temperatures. It can also be considered as the ability to maintain the original performance under a certain temperature change.

3. Mechanical strength, extension boat fracture resistance: Does not break under the load stress and deformation conditions within the allowable range of the building structure.

4. Flexibility: Special requirements for waterproof material with low temperature flexibility to ensure easy construction, not embrittlement.

5. Atmospheric stability: The ability to resist aging and resist erosion under the long-term comprehensive effects of sunlight, heat, oxygen, and other chemically eroding media and microbial erosion media.

The appearance requirements of the flexible water bladder

1. At -10-80°C, it should be easy to open without brittle cracking and damage to the rubber surface. The cloth should be completely saturated with rubber, and there should be no exposed cloth on the surface. The two layers of the shingle should be bonded together with glue material.

2. The surface protective layer must be continuously and uniformly bonded to the surface of the cloth to achieve a tight coverage. The rubber (sheet) material must be uniform, and the embedded mineral particles (sheets) should not cause damage to the material.

3, the surface should have rubber self-adhesive and protective tape.

4. There are no visible defects on the surface, such as holes, uncut edges, cracks, cracks, pits, and drums.
