Kiekie-Efficiency Planetary Screw no Plastic Processing Lako

NanhaiyaHiki i ka planetary screw 3D shearing system ke mālama i nā mea piha piha (e like me PP me ≥60% calcium carbonate filler a me PA me ≥40% glass fiber filler) a i ʻole nā ​​elastomers viscosity kiʻekiʻe (e like me TPU a me TPE), e hōʻemi ana i ka manawa plasticizing e 30% -50% i hoʻohālikelike ʻia me nā kuʻuna.ʻōnaehana hoʻokahi-screw.

ʻO ka hoʻohana ʻana i nā ʻōnaehana screw planetary e nānā nui ʻia i nā mea paʻakikī e lawelawe me nā ʻōnaehana hoʻokahi-screw kuʻuna, me nā noi kumu i hoʻopaʻa ʻia i ʻekolu mau wahi:

1. Kiʻekiʻe-filler plastic hana

Nā huahana maʻamau: Calcium carbonate i hoʻopiha piha ʻia i ka papa papahele PP (ka mea hoʻopiha piha 50% -70%), ke aniani fiber i hoʻoikaika ʻia ʻo PA automotive structural parts (filler content 30% -50%).

Waiwai kumu: Hoʻoholo i ka pilikia o ka hoʻopiha piha ʻana a me ka hōʻoia ʻana i nā ʻano mīkini like ʻole o nā huahana (e laʻa, ka hoʻololi ʻana i ka ikaika tensile ≤5%).

2. Elastomer a me ka hoʻololi ʻana i ka plastic plastic

Nā huahana maʻamau: ʻO nā mea pāʻani pāpaʻi palupalu TPR, nā ʻāpana hoʻopaʻa kaʻa TPE, nā paipu maʻalahi PVC (maʻiʻo plasticizer ≥30%).

ʻO ka waiwai kumu: ʻO ka hana haʻahaʻa haʻahaʻa e hōʻemi i ka volatilization plasticizer, ʻoiai ʻo ka ʻohi ikaika e hōʻoia i ka hoʻoheheʻe ʻana o ka elastomer, e pale ana i ka "pitting" ma ka ʻili o ka huahana.

3. Hoʻohuihui Mea Kūikawā a me Granulation

Nā Huahana Maʻamau: ʻO nā mea iila hoʻoheheʻe me ka pauka metala (e laʻa.

ʻO ka waiwai nui: ʻO ka hui ʻana ʻekolu-dimensional e hōʻoia i ka hoʻopuehu ʻana o ka pauka like ʻole (ka hoʻopuehu ≥ 90%), e pale ana i ka hana ʻole o ka huahana ma muli o ka hoʻohui ʻana o ka pauka.
