Ụdị Usoro Extrusion Plastic

A na-ekewa usoro extrusion plastik ka ọ bụrụ ụdị asaa dị iche iche dabere na ngwa ndị akọwapụtara.

(a) Mpempe akwụkwọ / ihe nkiri

N'ime usoro extrusion a, ihe plastik a wụrụ awụ na-apụ apụ site na anwụ dị larịị.A na-eji mpịakọta jụrụ oyi iji chọpụta nha mpempe akwụkwọ / ihe nkiri na ọdịdị elu ya.Enwere ike nweta ọkpụrụkpụ nke mpempe akwụkwọ na oke nke 0.2 ruo 15 mm.Enwere ike ịme mpempe akwụkwọ dị larịị ma ọ bụ ihe nkiri nke ihe plastik.N'ozuzu, a na-eji plastik polystyrene mee ihe dị ka ihe eji eme ihe na usoro mkpochapụ mpempe akwụkwọ.

(b) Mpụpụ ihe nkiri afụfụ

N'ime usoro ihe nkiri a na-efe efe, anwụ dị ka cylinder kwụ ọtọ nwere profaịlụ okirikiri.A na-eji otu ụzọ mkpọ nip na-adọkpụrụ rọba a wụrụ awụ elu site na anwụ anwụ.A na-eji ikuku abịakọrọ na-agbanye tube.N'akụkụ anwụ anwụ, a na-etinye mgbanaka ikuku.Ebumnuche nke mgbanaka ikuku bụ iji mee ka ihe nkiri ahụ dị jụụ ka ọ na-aga elu.N'etiti etiti nwụrụ anwụ, e nwere ikuku ikuku nke ikuku nwere ike ịmanye n'ime etiti profaịlụ okirikiri, na ịmepụta afụ.Enwere ike ịbawanye akụkụ obe okirikiri nke extruded ugboro 2-3 nke dayameta anwụ.A na-akụtu ụfụfụ ahụ site n'enyemaka nke efere na-ada ada.Ntụgharị nip ahụ na-eme ka afụ ahụ ghọọ okpukpu abụọ nke ihe nkiri a na-akpọ layflat.Enwere ike ịchịkwa mgbidi mgbidi nke ihe nkiri ahụ site n'ịgbanwe ọsọ nke rollers nip.Enwere ike ịkụnye layflat n'ụdị mpịakọta ma ọ bụ bee n'ime ụdị achọrọ.A na-emechi akụkụ ala nke layflat na ngwa ọkụ, ma bee n'ihu n'ihu iji mepụta oghere;ya mere enwere ike iji ya mee akpa rọba.Ogologo ya nwere ike ịdị iche site na 1 ruo 300 centimeters.N'ozuzu, a na-eji plastik polyurethane mee ihe na usoro a.

(c) N'elu Mpụpụ Jacketing

Nke a na-akpọkwa usoro mkpuchi waya.N'ime usoro a, a na-adọta waya na-enweghị isi n'etiti etiti anwụ.E nwere ihe abụọ dị iche iche nke extrusion tooling eji maka mkpuchi n'elu a waya ya bụ nrụgide ma ọ bụ jaketing tooling.Ọ bụrụ na achọrọ kọntaktị ma ọ bụ adhesion n'etiti waya na mkpuchi, a na-eji ngwá ọrụ nrụgide.Ọ bụrụ na achọghị adhesion, a na-eji ngwá ọrụ jaket mee ihe.Maka ngwá ọrụ nrụgide, a na-emegharị waya n'ime anwụ, ebe ọ na-abịa na kọntaktị na plastik a wụrụ awụ na nrụgide dị elu.Maka ihe eji eji akwa jaket, waya ga-agbatị na plastik a wụrụ awụ ga-eme mkpuchi na waya mgbe ọ nwụsịrị.A na-enye waya na-adịghị ahụkebe nri site na anwụ anwụ, ọ naghị abanyekwa na rọba a wụrụ awụ ozugbo ruo mgbe ọ hapụrụ anwụ.Isi ihe dị iche n'etiti jaketị na ngwá ọrụ nrụgide bụ ọnọdụ nke waya n'ihe gbasara ịnwụ.

(d) Mpụpụ tubing

N'ime usoro a, a na-ebupụ plastik a wụrụ awụ site na anwụ na-emepụta akụkụ obe ndị nwere oghere site n'itinye mandrel n'ime anwụ.Enwere ike ịme tube nke nwere ọtụtụ oghere maka ngwa ngwa, site n'itinye ọtụtụ mandrels n'etiti etiti anwụ.

(e) imekọ ihe ọnụ

Coextrusion bụ usoro extrusion nke ime ọtụtụ ihe n'ígwé n'otu oge.A na-eji ya na-etinye otu ma ọ bụ karịa n'ígwé n'elu isi ihe iji nweta kpọmkwem ihe ndị dị ka ultraviolet absorption, njide, matte elu, na ike echiche, mgbe isi ihe bụ ihe ndị ọzọ dabara adaba ngwa ndị ọzọ, eg mmetụta iguzogide na structural arụmọrụ.Enwere ike iji ya na usoro ọ bụla dị ka ihe nkiri afụfụ, n'elu jaketị, tubing, mpempe akwụkwọ/ihe nkiri extrusion.N'ime usoro a, a na-eji extruders abụọ ma ọ bụ karịa na-ebuga ihe ndị a na-ejikọta n'ime otu anwụ anwụ na-eme ka ihe ndị ahụ dị n'ụdị a chọrọ.A na-achịkwa ọkpụrụkpụ oyi akwa site na ọsọ na nha nke onye na-ebupụ ihe ndị ahụ.

(f) Mkpuchi mkpuchi

A na-eji mkpuchi nke extrusion mee akwa ọzọ n'elu akwụkwọ mpịakọta, foil ma ọ bụ ihe nkiri dị adị.Dịka ọmụmaatụ, iji melite mmiri na-eguzogide mmiri nke mkpuchi polyethylene akwụkwọ.Ngwa nke mkpuchi extrusion bụ nkwakọ mmiri mmiri, akwụkwọ foto, envelopu, mkpuchi akpa maka nkwakọ nri fatịlaịza na nkwakọ ọgwụ.N'ozuzu, a na-eji polyethylene na polypropylene mee ihe.
