Part 1: The Features of PVC Panel

Currently, more and more people would like to choose PVC Panel because of the features of below:

1. Economical: Low overall cost.

2. Thermal insulation: The thermal conductivity is 0.06-0.070W / (M.K), and the thermal resistance is about 10-20 times that of ordinary concrete.

3. Lightness: The dry bulk density is 200-300KG / M3, which is equivalent to about 1/5 to 1/8 of ordinary cement concrete, which can reduce the overall load of the building.

4. Compressive resistance: The compressive strength is 0.6-25.0MPA.

5. Integrity: It can be cast on site, and it is tightly integrated with the main project, without the need to leave a gap and a ventilation tube.

6. Low elasticity and shock absorption: The porosity of the PVC foam board makes it have a low elastic modulus, so that it has good absorption and dispersion of impact loads.

7. Simple construction: only need to use PVC foam board machine can realize automatic operation, can achieve long-distance transportation of vertical height of 200 meters, the workload is 150-300M3 / working day.

8. Sound insulation: PVC foam board insulation board contains a large number of independent bubbles, and is evenly distributed. The sound absorption capacity is 0.09-0.19%, which is 5 times that of ordinary concrete, and has the function of effective sound insulation.

9. Water resistance: The cast-in-situ PVC foam board has less water absorption, relatively independent closed bubbles and good integrity, so that it has a certain waterproof performance.

10. After adding the color masterbatch, the product can be made into a variety of colors. After being made into a weather-resistant formula, its color can be unchanged for a long time, and it is not easy to age.

11. It can be drilled, sawed, nailed, planed and glued like wood, and can be constructed using general wood processing tools. The finished product can be subjected to secondary thermoforming and folding, and can be directly bonded to other PVC materials

Part 2: Problems and Solution

Up to above, more and more PVC Foaming Panel factories established and attend the competition of selling market. Many factories has met some problems during the extruding and dont know how to solve it, it makes the sell work become difficult. Now we HENGSHUI HOMART TECHNOLOGY (JIUZ GROUP)will help you conclude the problems mainly happened during producing and list the solutions, hope it will give you hand in future.

1. The surface of the PVC Panel is yellow

The extrusion temperature is too high or the stability is insufficient. The solution is to reduce the processing temperature. If the improvement does not improve, the formulation can be adjusted. The stabilizer and lubricant can be added appropriately. It can be changed one by one. It is easy to find out the problem quickly and solve the problem at the fastest speed .

2. The middle of the PVC Panel is yellowed.

The main reason is that the temperature of the core of the barrel is high and the temperature of the mold is also related to the amount of lubricant. Once again, it has a certain relationship with the white foaming agent.

3. PVC Panel bending.

Uneven material flow or inadequate cooling, the factors causing uneven material flow are generally large traction fluctuations or unbalanced internal and external lubrication in the formula. The factors of the machine are easy to eliminate. Formula adjustment generally adjusts internal lubrication under the premise of as little external lubrication as possible Very good results, while ensuring that the cooling is evenly in place.

4. PVC Panel Foam cells or bubble delamination appear on the cross section.

The reason can be attributed to one point, that is, the melt strength is not enough. The reasons for the insufficient melt strength are:

1. Excess foaming agent or insufficient foaming regulator or inconsistent ratio of the two, or quality problem of foaming regulator.

2. Poor plasticization, low processing temperature or excessive lubrication

5. The thickness of PVC Panel is uneven.

Uneven material output, adjustable die lip opening, if the flow rate is too large, the choke bar can be adjusted, the formula is adjusted, generally the inner lubrication has more middle thickness, and the outer lubrication has more feeding on both sides.

6. The change of PVC Panel thickness and thin lines that are easy to occur during handover

The main reason: it is related to the mixing. After the last shift, the interval between the mixing is long after the next shift. The mixing barrel is cooled well. The first pot of the mixing is pre-plasticized, which is the same as before Differences are formed, and when other conditions remain unchanged, fluctuations are likely to occur, which can be adjusted by adjusting traction, processing temperature, or through management.
