Solutions to problems in the production of PP plastic particles
The common problem in the production of pp plastic particles is that the particles are more than twice the normal. At this time, the process needs to be adjusted. Pay attention to the inspection of the pelletized motorized knife and replace the damaged movable knife in time. For the long strips, a suitable vibrating screen can be used for sieving. .
Sometimes there will be two or more pp plastic particles connected to the particles, the main reasons are broken strips when pulling, the length of the water is not enough, etc. When extruding the draw bar, use a guide bar with a suitable width, separate the connected bars, and adjust the appropriate cooling water length to reduce the continuous particles. For the continuous particles, a suitable vibrating screen can be used to screen .
When there are black spots on the surface of pp plastic particles, it means that the machine is not clean, there are black spots in the raw materials or it is polluted by the environment, as long as the machine is cleaned again, incoming inspection is strengthened, and the surrounding environment is protected.
Selection method of high quality PP plastic particles
There are many different manufacturers in the recycled PP plastic pellet market. The quality of the recycled plastic pellets is different. We need to compare the quality of the recycled plastic pellets. How to separate more high-quality recycled plastic pellets, we need some the way.
To see whether the brightness of the surface of recycled plastic particles is transparent, let's take a look at the whiteness of recycled plastic particles, not just the whiteness surface, but also the intersection. Therefore, as a better distinction between high-quality recycled plastic particles, let us try the hardness of recycled plastic particles, bite the bar with a bite of recycled plastic particles, the excellent quality is hard and soft, we give it up, it is definitely not a Good recycled plastic particles. Recycled plastic particles are on the surface of the water. You can also make recycled plastic particles look like they are not submerged by water. They cannot be submerged in pure recycled plastic particles.
