Usoro mmeghe

A na-arụpụta 3/4 nke ngwaahịa a na-akpụ akpụ site na ịkpụzi extrusion.Usoro extrusion bụ ịmanye ihe site na oghere ma ọ bụ nwụọ iji mepụta ngwaahịa.

The extrusion igbu ịkpụzi usoro mejupụtara 5 nzọụkwụ: 1. Plastic preform (extrusion nke oghere plastic tube).2. Mechie flap ebu na parison, kụchie ebu ahụ ma bepụ parison ahụ.3. Gwuo ihe ọkpụkpụ ahụ na mgbidi oyi nke oghere ahụ, gbanwee oghere ma nọgide na-enwe nrụgide ụfọdụ n'oge oyi.4. Mepee ebu ma wepụ akụkụ ndị afụfụ.5. Kpochapụ flash ahụ iji nweta ngwaahịa emechara.

Extrusion oghere igbu ịkpụzi usoro
Ịkpụzi ihe mkpofu oghere bụ ịgbaze na rọba plastik n'ime extruder, wee wepụ parison tubular site na tubular die.Mgbe parison ahụ ruru ogologo ogologo, parison ahụ na-ekpo ọkụ n'ime ihe ọkụkụ ahụ.Mgbe ahụ, a na-afụ ikuku emetụtara iji mee ka parison dị nso na mgbidi nke oghere ọkpụkpụ iji nweta ọdịdị nke oghere ahụ, na n'okpuru ọnọdụ nke ịnọgide na-enwe nrụgide ụfọdụ, mgbe ọ dị jụụ na ịkpụzi, a na-enweta ngwaahịa a na-agbapụta site na ịkwatu.Usoro nke extrusion igbu ịkpụzi bụ ndị a.
Plastic → plasticizing na extrusion → tubular parison → ebu imechi → onu oriri ịkpụzi → jụrụ oyi → ebu oghere → wepụ ngwaahịa ahụ
Enwere ike kewaa ịkpụ akpụ akpụ n'ime usoro ise ndị a, dịka egosiri na eserese 1-1.
① A na-agbaze polymer site na extruder, na gbazee na-etolite n'ime a tubular parison site na anwụ.
② Mgbe parison ahụ ruru ogologo oge a kara aka, a na-emechi ihe ọkụkụ ahụ, a na-akụchi parison ahụ n'etiti akụkụ abụọ ebu, a na-egbutukwa parison ahụ gaa n'ọdụ ọzọ.
③Gbanye ikuku abịakọrọ n'ime parison iji fesa parison ka ọ dị nso n'oghere ebu iji mepụta.
④ daa jụụ.
⑤Mepee ebu ma wepụ ngwaahịa a kpụrụ akpụ.
