Typical values 1-4, 11 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 4 hours.

*Especially, these typical values were tested by press moulding sample (A and B mixed atpercentage 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 4215

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

(℃)

150~165

165~177

175~190

190~200


Die head setting:
Squeezing extrusion style and tubing extrusion style

Cooling water temperature: Should not be less than 25℃, when using tubing style extrusion method, gradual cooling water tank is recommended for better control the heat shrinkage.

   

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:What is the difference between a kbg threading pipe and a PVC threading pipe?
The expression is not very clear, it should be said to wear a tube, if a single wear on the line 100. Outside diameter 60mm.
Q:Ipad charging display does not support this accessory
Ipad charge display does not support the general reasons for this and processing methods: . for non-original charger, it will often appear this situation, which is due to the charger does not meet the specifications caused by the replacement of a qualified charger can be. . if the original charger appears the above failure, please continue to look down. . please check whether the data line is normal. The appearance of the data lines seem normal, which may have been broken. Check the method is to borrow someone else's data line to see if it can charge. . shows the plug symbol is normal is full of display. If full or show the lack of electricity, indicating that the phone tail no problem. . again, check whether the original charger can work properly. You can connect the charger to other USB port to see if the phone is working properly. . if the above two check still can not charge, please try to insert the computer's USB port to see if the computer can identify the phone, to identify if it is to see if the charge, if not identified but not charged, it is estimated that the need for maintenance. If you can not identify can not charge, it is necessary to repair. If you can recognize and charge, replace the data cable and the charger (the original estimate is also damaged). . and then look at the voltage is not too low, not only to the maintenance station to repair, and pay attention to the iPad and iPhone do not mix the power adapter, the voltage is different.
Q:The computer can not open the machine display frequency beyond the scope of the mouse and keyboard do not start can not press F8 how to do
Then you get the repair station to see what is the problem
Q:2.5 square copper (green, with the threading tube) can withstand the highest power of several kilowatts,
The electrical part of the decoration is laid by the electrician, as long as you tell him the power of your home and the equipment used, the electrician will tell you how much to buy the large diameter line, and the number and color needed.
Q:What is the difference between wires and cables?
The introduction of the device in the form of: sealing ring (sealing ring is to achieve the required protection level of the shell and the use of cash-saving brush to help find the silent material or elastic material parts) type of introduction device; casting solidified packing seal Type introduction device; metal seal ring introduction device
Q:What is the current good computer configuration on the market? The price of 4000 yuan or so no more than 4000 assembly parts to write down the price Thank you.
No way to save money! Moreover, the signal to you there, almost all attenuation finished.
Q:Connect the computer to the TV. The The Using the HDMI cable. The The Line no problem. The Why not even after the audio video. The The Amplifier is Denon 1311
BV1 * 2.5 is a 2.5 square line. 2 * 2.5 is two 2.5 square lines. 3 * 2.5 is three 2.5 square lines. 4 * 2.5 is the 4 2.5 square line lighting wire power cord with 2 * 2.5. Light wire with 1.5 is enough. Socket (pipe) with three 2.5 square lines, you can also use 3 * 2.5 a. 4 * 2.5 for three-phase motors.
Q:What does the letter of the computer cable model mean?
Cable regardless of the definition of the number of elements in the definition of a few such as: YJV-3 * 50 + 1 * 16 calculated the number of lines is always a different, different wire rules Model input: bv-2 * 2.5 / bv-3 * 4 (different material), bv-2 * 2.5 + 3 * 4 (the same material)
Q:Is the toilet wire walk on the ground? Are there any hidden dangers?
The proportion of the cross-sectional area of the cable through the embedded pipe is 20%
Q:Automotive wiring harness welding to pay attention to what the problem
When the lighting circuit and the power circuit shared ladder, BV line is not allowed to put in the ladder, so it is recommended to use the wiring of the lamp ZC-YJV-3 * 2
