Typical values were tested on the sample strip by squeezing film extrusion after mixing compound of A & B(at percentage of 90:10) and be boiled in hot water at 90℃ for four hours.
*Especially, these typical values were tested by press moulding sample (A and B mixed at percentage of 90:10), under the condition of 180±2 ℃, 15min, and pressure over 15Mpa, then boiled in 90℃ water for four hours.
Recommended Processing Technique
1. Extrusion Equipment
Most extruders for PVC and PE suit for 4245
The recommended equipment and processing technique is as following.
Ratio of length and diameter 18—25:1
Diameter 45—120mm
Ratio of compressing 1.5—3.5
Ratio of elongation 1:1.0—1:1.5
Filtering mesh 40/60/40
2. Extruder processing temperature and other related settings
Temperature Setting: Specific processing temperature should be based on different equipment and pressing conditions, reference settings are as following:
Feeding Section(℃) | Compression Section(℃) | Measurement Section (℃) | Die head and Mould (℃) |
135~155 | 155~170 | 170~180 | 180~200 |
Die head setting: Tubing extrusion style is recommended.
3. Crosslink
After extrusion and cooling, the cable can be crosslinked by immersed in hot water (90℃) or exposed in low pressure vapour. The time required for crosslink is based on the thickness of the insulation and the coil size, the thicker the insulation and the greater the coil size, the longer the crosslink time required. The crosslink time can be calculated according to the equation of 4hr/mm for 90℃.
- Q:Decoration when the purchase of water pipes, wires and other items included in the account
- Outdoor fire line must use fire-resistant KVV cable, wear pipe protection.
- Q:What are the varieties of wire and cable (detailed point)
- (The difference between the two cables: WDZ and WDZC are the combustion characteristics of the cable, both halogen-free low smoke flame retardant cable, but the former is a single vertical flame retardant test, which is bundled combustion C class flame retardant Test, but the flame retardant performance requirements are not the same. The meaning of the letter: W refers to the halogen-free; D refers to the low smoke; Z refers to the flame retardant WDZ is halogen-free low smoke flame retardant jacket power cable. WDZC refers to halogen-free low smoke C-class flame retardant reference )
- Q:If you want to sell wire and cable, then what to do in advance to detect? The The The The The
- Line width, and can not pass the gap between the chip pins, even after, but also because the distance between the wire and the lead is less than the electrical rules specified in the safe distance. In general, the ground can not pass through the gap between the chip pins, go outside or take the gap between the two columns through the gap. The width of the ground wire can also be set appropriately, and the wire is widened by adding a polygon brass cut. The safety distance in the electrical rules defaults to 10 mils, which is relatively small, and the safety distance of the different networks should be set separately as needed.
- Q:Do not know why not mislead. The The The The The Fire resistance is IECGBBS6387. GB is the general principle of flame retardant and fire resistant wire and cable, quoted the above criteria...........................
- About 140 PVC threading tube, which depends on how many lines you row. PPR cold / hot water pipe 42 meters, PPR cold / hot water pipe with 4 m / root and 6 m / root of the points, short will make the joints more recommended to use long, generally longer expensive. Decoration in meters to count, to facilitate the settlement of labor, 42 meters is the amount of my home My house 115 square meters, indoor area of 98 square meters. I hope useful to you. According to the 2011 price, the general brand of wires and pipes, their own materials to buy, without artificial about 4000-5000 yuan. I decorated last year, the package to the decorating company hydropower workers with me to calculate the 9800 yuan it, of course, each region has a price difference.
- Q:Four lines only reached a phase line, at the other end all charged, I use the digital pen! In addition, I often check the cable when the cable current through the dot digital pen voltage symbols sometimes have time to disappear, in other bare wires when the test keys are normal! What is this going on! Ask the heroes to give the younger brother a complete point of the answer! More
- There are [the top of the machine can be broken off the ball can be hit by Jiu turtle snow box video output cable and DVD video output line] into a junction box, and then through the sub-box toggle switch to select the 'set-top box' or 'DVD'; This junction box outputs a wire connection device or is connected to a TV.
- Q:Remove the computer and wash it off. What the motherboard did not move it, that is, the dust of those dust sasses, as well as the other wire of the skin what Sassafras wash, but the computer re-connected to the Internet when the old mistakes . and the lower right corner of the red Fork appears, disappeared after the emergence. The The Said the network cable is not plugged in, but the MODERN that POWER, LINK, LINE, 3 lights are normal display. The The This is how the matter, and just also appeared keyboard and mouse just start the machine can also be used normally, but in a moment to fall, and then plug their plug re-plug the mouse lights can be displayed, but the lights on the keyboard simply do not Bright, restart the computer but good, what is going on? bother. The The I hope the master quickly to help me, and this machine is relatively old ah No problem added: on a machine, just tried to re-create a connection in the network neighborhood, useless more
- No need. Galvanized flat iron to do when the grounding grid is not anti-corrosion, but if there is welding or damaged place to become anti-corrosion.
- Q:What is the difference between wires and cables?
- The introduction of the device is to introduce the cable into the electrical equipment, without changing the explosion-proof type of explosion-proof equipment
- Q:Wire and cable model ZD what does it mean
