A、 Equipment usage:

1. Special twin-screw extrusion filling grouting equipment for fire-resistant filling mineral materials of mineral insulated cables, flexible fire-resistant cables, fire-resistant cables, ultra A flame-retardant power cables, etc.

2. Production of fire-resistant cable specifications and models: NG/A-BTLY BTLV BTLYQ BTLVQ BBTRZ BBTRQ BTTWY WTGE BTMMRZ YTLHWY NG/B ZG/A GA-YJY TBTRZY GAN-BTGYZ GAN-BTGZ, etc.

3. B1 class cable oxygen and fire insulation layer grouting extrusion filling equipment. B1 cable specifications and models: WDZB1-YJY WDZB1-YJY23 WDZB1N-YJY WDZB1N-YJY23 WDZB1N-KYJYP23 WDZB1-KYJYP, etc.

B、 Advantages of production line technology:

1. Efficient twin screw, screw diameter φ 140mm, bottom diameter φ 80mm, screw edge depth 30mm, compression ratio 1.286, gradient screw, high extrusion pressure, has a great promoting effect on poor fluidity oxygen resistant and fireproof mud materials, and has a secondary mixing effect on the extruded materials. When installing two screws, strict correspondence is required, with the screw edge to the screw edge and the screw groove to the screw groove.

2. Head structure: Head conical feeder, feed end diameter φ 160mm, extrusion die end diameter φ 140mm, the depth of the feeder is 25mm, effectively increasing the extrusion pressure, and the conical structure is easy to disassemble and clean.

3. Flange head: greatly increases extrusion pressure, and the screw can be removed by removing the flange, making it very convenient to clean the screw.

4. Provide three types of oxygen and fire resistant mud material formulas: using composite flame retardant and water glass, add the required retarder, curing agent and other materials to the powder in advance and stir thoroughly. Workers do not need to weigh the ratio during mixing, and add a certain amount of water glass when the material is hard; When the material is diluted, add a certain amount of flame retardant to facilitate user use. And a certain amount of magnesium oxide is added to the flame retardant to react with water in the water glass, accelerating the solidification process of the fireproof mud and improving the roundness of the cable. Magnesium oxide MgO+water H2O → Magnesium hydroxide Mg (OH) 2.

5. Reverse half cut wrapping machine: It eliminates the problem of oxygen resistant and fireproof mud material being scratched by wire core shaking and the center hole of the wrapping machine, and greatly improves the production line output speed.

6. The crawler tractor adopts a double R groove structure, combined with a fast curing oxygen and fire resistant mud, making the equipment easy to install, aesthetically pleasing in appearance, and easy to use.

7. Hydraulic dust-free mixer: stainless steel spiral mixing blades, durable and long-lasting; 200kg of oxygen resistant and fire-resistant mud material can be mixed in a single time, with a dust-free mixing time of 5-10 minutes. The mixing efficiency is high, and it is environmentally friendly and dust-free; The hydraulic cylinder drives the cylinder to flip and automatically dispense materials, making it convenient and fast.
