PP PE pelletizing afiri .

PP PE pelletizing machine is a complete set of equipment that converts PP (polypropylene) and PE (polyethylene) waste plastics (such as films, bottles, woven bags, household appliance shells, etc.) into high-value, high-purity recycled plastic particles through processes such as melting, filtering, extrusion, cooling, and cutting.

Granulation yɛ anammɔn a ɛkɔ akyiri a ɛho hia sen biara wɔ plastic adwuma a wɔasan de adi dwuma no mu. Sɛ wɔde toto nneɛma a wɔabubu ho (flakes) ho a, granules yɛ pɛ, ɛnyɛ den sɛ wɔde bɛkɔ na wɔde asie, na agye din kɛse wɔ wɔn a wɔyɛ nneɛma a ɛwɔ fam no mu, na ɛnam so ma ne bo yɛ den.

3. Filtration pɛpɛɛpɛ: Screen changer no yɛ granulation line no kra. Mesh kɛse a ɛwɔ filter no mu no kyerɛ ahotew ne bo a ɛsom wɔ nneɛma nketenkete no ho tẽẽ. Sɛ wopɛ sɛ wonya nneɛma a ɛkorɔn-End nneɛma a, ɛsɛ sɛ wode mesh filter a ɛkorɔn a ne kɛse yɛ 80 anaa nea ɛboro saa di dwuma.

4. Raw material pretreatment: Ɛsɛ sɛ aduan no yɛ nwunu na dade biara nni mu. Nsu a ɛwɔ mu no betumi ama ahurututu aba nneɛma nketenkete no mu, na aka wɔn su; Dade betumi asɛe nkɔnsɔnkɔnsɔn ne nsuhina a ne bo yɛ den no kɛse.

5. Ahoɔden a wɔkora so ne nneɛma a atwa yɛn ho ahyia ho banbɔ:

·Ahoɔden a wɔkora so: Nnɛyi granulators taa yɛ nea ahoɔden-gye mfiridwuma te sɛ electromagnetic ɔhyew, a ɛma anyinam ahoɔden bɛboro 30% sɛ wɔde toto atetesɛm mu ahoɔden a ɛko tia ɔhyew ho a.

·Abɔdeɛ a atwa yɛn ho ahyia ho banbɔ: Nsuo a ɛrebɔ no ma mframa a ɛyɛ fĩ (VOCs) kakraa bi ba, a ɛhia sɛ wɔboa mfiri a wɔde yɛ nwura a wɔde yɛ adwuma (te sɛ activated carbon adsorption, electrostatic wusiw a wɔyi firi hɔ, ne nea ɛkeka ho) na ama wɔatumi adi nneɛma a atwa yɛn ho ahyia ho banbɔ ho ahwehwɛdeɛ ho dwuma.

Mewɔ anidaso sɛ nhwehwɛmu a ɛkɔ akyiri yi betumi aboa wo ma woate PP/PE granulation production line no ase yiye. Sɛ wowɔ nneɛma pɔtee bi a wɔde yɛ nneɛma (te sɛ sini a ɛho tew, nkotoku a wɔadi afra, ne nea ɛkeka ho) a ɛsɛ sɛ wɔyɛ ho adwuma a, nnwinnade a wɔbɛpaw ne sɛnea wɔahyehyɛ no bɛsakra.
