Difference between waterproof cable and water blocking cable

Waterproof cable: It is to prevent water from entering the interior of the cable structure. The structure and material with waterproof function are adopted on the cable sheath.
Water blocking cable: It is the assessment that allows water to enter the interior of the cable, but it is not allowed to penetrate to the specified length under the specified conditions. Water blocking cable is divided into conductor water blocking and cable core water blocking.
Conductor water blocking structure: Generally, water blocking powder and water blocking yarn are added during the monofilament stranding process between the strands of the stranded conductor. When the conductor enters the water, the water blocking powder or the water blocking yarn inflates with water to prevent the water from penetrating. Of course, the solid conductor has the best water blocking performance.
Cable core water blocking structure: single core cable is more convenient, one or more layers of water blocking tape are wrapped around the copper shield, and then the outer jacket is squeezed. When the outer jacket is damaged and water enters, the water blocking belt expands due to water swelling. The inner and outer surfaces of the water-blocking zone are all cylinders. When the water-blocking zone expands, a water-blocking section is formed quickly, which prevents the further penetration of water. For the three-core cable, it is very difficult for the cable core to completely block water because the three cores The middle gap of the cable core is large and irregular, that is, all the water blocking tapes are filled, and the water blocking effect is also not good. It is suggested that each core should be produced by a single core water blocking structure and then be cabled.

[Dilution Method]:

With 4-6 times the water and stir to dissolve dilution.


[Direction for Usage]:(To dilute finished product as an example)

A. Padding Process: 5-20g/L, temperature 40°C-60°C, PH Value:5-8, One-dip-one-nip or Double-dip-double-nip.

B. Dipping process: 1-4% (O.W.F), Room temperature 40°C-60°C, PH Value:5-8, bath ratio:1:8-12,Time: 20-30 min.


1. Concentrated Formaldehyde-free Fixative Fixing Agent has good color fixing property, can obviously improve the dyeing or printing of fabric soaping, washing fastness and wet rubbing fastness.

2. Can be used for much of the association between dye fixation, anti fading property, does not affect the dyeing or printing of fabric vividness. No effect for the original feel, processing fabric has excellent hydrophilic.

3. Formaldehyde-free Fixative  widely used for dyeing or printing of the direct, active dye fixing finishing, good fixation effect, especially for the red dye and Cuilan dyes, particularly prominent, fixation is better than the general Formaldehyde-free Fixative.

4. The dye PH value for a wide range, acid, alkali resistance, resistance to hard water, high temperature resistance, an environment-friendly products, does not contain formaldehyde.
