Plastic extrusion, makwaara dị ka plasticating extrusion, bụ a na-aga n'ihu elu olu n'ichepụta usoro nke a thermoplastic ihe onwunwe - n'ụdị ntụ ntụ, pellets ma ọ bụ granulates - homogeneously gbazee wee na-amanye si n'ịkpụzi anwụ site na nrụgide.Na ịghasa extrusion, nrụgide na-abịa site na ịghasa ntụgharị megide mgbidi gbọmgbọm.Ka plastik na-agbaze na-agafe na anwụ anwụ, ọ na-enweta ọdịdị oghere anwụ wee hapụ onye extruder.A na-akpọ ngwaahịa a na-ekpochapụ extrudate.
Ihe na-ahụkarị extruder nwere mpaghara anọ:
Mpaghara nri
Na mpaghara a, omimi ụgbọ elu na-adịgide adịgide.Ebe dị anya n'etiti isi dayameta dị n'elu ụgbọ elu na obere dayameta nke ịghasa na ala nke ụgbọ elu bụ omimi ụgbọ elu.
Mpaghara Mgbanwe ma ọ bụ Mpaghara mkpakọ
Omimi ụgbọ elu na-amalite ibelata na mpaghara a.Dị ka a pụrụ isi kwuo ya, a na-ejikọta ihe thermoplastic ma malite ịme plastik.
Mpaghara ngwakọta
Na mpaghara a, omimi ụgbọ elu na-agbanwe agbanwe.Iji hụ na ihe ahụ gbazere kpamkpam ma jikọta ya n'otu n'otu, ihe ngwakọta pụrụ iche nwere ike ịdị.
Mpaghara mita
Mpaghara a nwere omimi ụgbọ elu pere mpe karịa na mpaghara agwakọta mana ọ na-adịgide.Ọzọkwa, nrụgide na-akpali gbazee site na ịkpụzi anwụ na mpaghara a.
N'ikwu ya n'ụzọ ọzọ, agbaze nke ngwakọta polymer bụ isi ihe atọ kpatara:
Nyefee ọkụ
Nfefe ọkụ bụ ike ebufere site na moto extruder gaa na ogwe aka extruder.Ọzọkwa, polymer na-agbaze na-emetụta profaịlụ nke skru na oge obibi.
Esemokwu
Nke a na-ebute site na esemokwu dị n'ime nke ntụ ntụ, profaịlụ ịghasa, ịghasa ọsọ na ọnụego nri.
Barrel Extruder
A na-eji ndị na-ahụ maka ọnọdụ okpomọkụ nọọrọ onwe ha atọ ma ọ bụ karịa iji kwado okpomọkụ nke gbọmgbọm ahụ.
