The difference between PVC and PP

1. color difference:

PP material can not be made transparent, commonly used colors for the original color (the natural color of the PP material), beige gray, porcelain white, etc. PVC color is richer generally have dark gray, light gray, beige, ivory, transparent, etc.?

2. Weight difference:

PP board is less dense than PVC board, PVC density is a little higher, so PVC heavier.

3. Degree of acid and alkali resistance:?

PVC acid and alkali resistance than the degree of PP board will be a little better, but the texture is more brittle and hard, anti-ultraviolet radiation, can withstand climate change for a long time, non-flammable, light toxicity. But PP board is not UV protection, sunlight for a long time will change color.

4. Temperature difference ?

National brands: PP's temperature range is about 0 to 80 degrees Celsius, PVC's range is 0 to 60 degrees Celsius.

Imported brands: PP temperature range is about 0 to 100 degrees Celsius, PVC temperature range is -40 to 95 degrees Celsius.

pvc pipe leakage treatment

First step: find the leak. Leakage will always have a source, right, the general water pipe is embedded in the wall inside, when the water pipe leakage, the wall is seeping wet, but still can look at the leakage in what place. The water is from top to bottom, so follow the wet traces of the wall all the way to find, or can find the leakage of the water pipe.

Step 2: Mark the leaky pipe. If the water pipe is indeed inside the wall, then you need to hire a worker to punch a hole and open the wall. If the leaking water pipe is outside the wall, it's a good idea. Check what material the water pipe is made of. Such as plastic, steel, PV, etc.

Step 3: Waterproof tape. This can be bought at the hardware store, it's cheap. In the leaky water pipe outside the first waterproof tape (also known as waterproof paper) wrapped in a few layers, and then wrapped in a layer of foam glue on the outside, and then wrapped in waterproof paper outside the foam glue, and then wrapped in a layer of waterproof paper outside the foam glue, and then finally hit the glass glue on the OK!
