ʻO ke kuʻekuʻe ʻana i nā māhoe māhoe hoʻololi ʻana

He mea maʻalahi ka hoʻolālā ʻana o ka māhoe huli -screw. Ma muli o ka wiliwili ʻana o nā wili ʻelua ma nā ʻaoʻao ʻē aʻe a me ka liʻiliʻi o nā wahi hoʻopili ma waena o lākou, ʻoi aku ka haʻahaʻa o nā koi kūpono no ke kūpono ma waena o nā ʻili. I loko o ka māhoe hoʻoheheʻe māhoe ʻōniu -screw, ua like ka lawe ʻana i nā mea me ke ʻano hoʻoneʻe maikaʻi i loko o kahi pahu pahu. ʻO ka hiʻohiʻona o kēia extruder ʻo ia ka wikiwiki rotational haʻahaʻa, e hōʻemi ana i ka wela i hana ʻia e ka ʻāʻili ʻana a hoʻohaʻahaʻa i ka hopena o ka decomposition waiwai. No laila, loaʻa iā ia nā koi haʻahaʻa no ka paʻa ʻana o ka wela o nā mea a he kūpono loa ia no ka hoʻoheheʻe ʻana a me ka hana ʻana o nā mea wela e like me PVC.

ʻOi aku ka maikaʻi o ka lawe ʻana, ʻoi aku ka maikaʻi o ka exhaust a me nā hopena heheʻe. ʻOiai ʻoi aku ka haʻahaʻa o kāna hoʻopuehu ʻana a me ka hui ʻana, hiki iā ia ke hoʻokumu i ka paʻa paʻa o ke poʻo, e lilo ia i koho kūpono no ka extrusion pololei o nā huahana. Eia kekahi, hiki ke hoʻokuʻu ʻia ke kaʻina hana granulation pre plasticization a hiki ke hana pololei ʻia ka pauka PVC e hōʻemi i nā kumukūʻai huahana.
Ma ke 'ano ma'amau, ho'ohana nui 'ia ka māhoe conical anisotropic-screw extruder no ka ho'oku'u 'ana i nā huahana polyvinyl chloride (PVC). Eia nō naʻe, i kēia mau makahiki i hala iho nei, ua hōʻike kekahi mau hana kūloko e hiki ke hoʻohana pono ʻia ka māhoe conical māhoe anisotropic -screw extruder i ka extrusion o nā paipu polyolefin (e like me ka polyethylene, PE). ʻO ke kumu nui no ka hoʻohana ʻana i ka māhoe conical māhoe anisotropic-screw extruder e hoʻopau i nā paipu polyolefin ʻo ia ka mālama ʻana i ka ikehu a hoʻemi i nā kumukūʻai.

No ka laʻana, he 65mm anawaena conical twin-screw extruder me ka 132um spacing screw he 37kW wale nō ka mana kaʻa kaʻa, aʻo ka 75mm a i ʻole 80mm single screw extruder me ka mana hoʻokele ʻaʻole emi ma lalo o 90kW. 'O ia ho'i, ma ka puka like a i 'ole like paha, hiki i ka mea ho'ohehe'e māhoe conical twin -screw extruder ke hā'awi aku i ka ikehu maika'i.
Pono e hoʻomaopopo ʻia ma muli o ka ʻokoʻa nui o nā ʻano kahe ma waena o ka polyolefin melt a me ka polyvinyl chloride melt, i ka wā e hoʻohana ai i ka anisotropic conical twin -screw extruder no ka PVC a hiki i ka polyolefin pipe extrusion, pono e hoʻoponopono ʻia ka hoʻolālā wili e hōʻoia i ka hana pono ʻana o nā mea polyolefin, a pono ke hoʻololi ʻia i ke poʻo.

ʻO ka co rotating twin -screw extruder, ma muli o kāna mau hiʻohiʻona i hoʻopilikino ʻia a me ka ʻike loea kiʻekiʻe, ua hoʻolālā ʻia me ka pololei a me ka paʻakikī; Ma keʻano o ka mālamaʻana, pono e hoʻonui i ka manawa a me ka ikaika i ka hoʻoponopono maikaʻi. Ua lanakila ka 'ao'ao māhoe -screw extruder i ka makemake o kekahi mau mea hoʻohana me kona hoʻolālā maʻemaʻe a maʻemaʻe, ʻoi aku hoʻi i nā hiʻohiʻona noiʻi e ʻimi ana i ka paʻa a me ka hilinaʻi.
ʻO ka ʻaoʻao o ka rotating twin screw extruder he mea hana kūikawā kūpono no ka hoʻoheheʻe ʻana i nā pauka PVC like ʻole. Hoʻolako ʻia me nā mīkini ʻokoʻa a me nā mīkini kōkua, hiki iā ia ke hana i nā ʻano like ʻole o nā paipu plastik PVC, nā profiles, nā papa, nā ʻāpana, nā pā a me nā pellets.
 

Nā huahana pale: ʻO nā mea kūʻai aku, nā mea hoʻolako, nā hale hana, Kina e like me ka rotating twin screw extruder.
