Okwu Mmalite nke Plastic Extrusion
Mpụpụ plastik bụ otu n'ime usoro mmepụta ihe a na-ejikarị eme ihe na ụlọ ọrụ plastik, karịsịa maka thermoplastics. Yiri ịkpụzi injection, a na-eji extrusion mepụta ihe nwere profaịlụ na-aga n'ihu, dị ka ọkpọkọ, tubing, na profaịlụ ụzọ. Extrusion thermoplastic nke oge a abụrụla ngwá ọrụ siri ike maka ihe fọrọ nke nta ka ọ bụrụ otu narị afọ, na-eme ka mmepụta dị elu nke akụkụ profaịlụ na-aga n'ihu. Ndị ahịa na-arụkọ ọrụ na ụlọ ọrụ extrusion plastik iji mepụta extrusions plastik ahaziri maka mkpa ha kpọmkwem.
Isiokwu a na-abanye n'ime ihe ndị bụ isi nke extrusion plastik, na-akọwa otú usoro ahụ si arụ ọrụ, nke a na-emepụta ihe ndị na-ekpo ọkụ na-ekpo ọkụ, ihe ngwaahịa ndị a na-ejikarị eme ihe site na ntinye plastik, na otú extrusion plastik si atụnyere nkwụsị nke aluminum.
Usoro Extrusion Plastic
Iji ghọta usoro extrusion plastik, ọ dị mkpa ịmara ihe extruder bụ yana otu o si arụ ọrụ. Dịka, extruder nwere ihe ndị a:
Hopper: Na-echekwa ihe eji eme rọba.
Nri Akpịrị: Na-enye nri plastik si na hopper banye gbọmgbọm.
gbọmgbọrọ akpọnwụ akpọnwụ: Nwere skru nke moto na-ebugharị, nke na-akpali ihe ahụ gaa n'ọnwụ.
Plate Breaker: Ejiri ya na ihuenyo iji nzacha ihe yana ịnọgide na-enwe nrụgide.
Feed Pipe: Na-ebufe ihe mgbaze na gbọmgbọm gaa n'ọkụ.
Nwuo: Na-akpụzi ihe ahụ ka ọ bụrụ profaịlụ achọrọ.
Sistemụ jụrụ oyi: Na-eme ka otu akụkụ nke extruded siri sie ike.
Usoro extrusion plastik na-amalite site na iji ngwa ngwa siri ike mejupụta hopper, dị ka pellets ma ọ bụ flakes. A na-enweta ihe ike ndọda site na akpịrị nri n'ime gbọmgbọm nke extruder. Ka ihe na-abanye n'ime gbọmgbọm ahụ, a na-ekpo ọkụ site n'ọtụtụ mpaghara kpo oku. N'otu oge ahụ, a na-akwagharị ihe ahụ gaa na njedebe anwụ nke gbọmgbọm site na ịghaghachi azụ, nke moto na-ebugharị. Ihe nkedo na nrụgide na-emepụta okpomọkụ ọzọ, ya mere, mpaghara kpo oku ekwesịghị ịdị ọkụ dị ka okpomọkụ extrusion ikpeazụ.
Plastic a wụrụ awụ na-esi n'ígwè ahụ pụta site na ihuenyo nke efere ihe nbibi gbasiri ike, bụ́ nke na-ewepụ ihe ndị na-emerụ emerụ ma na-edobe nrụgide otu n'ime gbọmgbọm ahụ. Ihe ahụ na-agafe site na ọkpọkọ nri na-adaba na omenala anwụ, nke nwere oghere dị ka profaịlụ extruded chọrọ, na-emepụta extrusion plastik omenala.
Dị ka ihe a na-amanye site na ịnwụ anwụ, ọ na-ewere ọdịdị nke oghere nwụrụ anwụ, na-emecha usoro nkwụsị. A na-emezi profaịlụ extruded ahụ dị jụụ na mmiri ịsa ahụ ma ọ bụ site na usoro mpịakọta oyi iji sie ike.
Plastics extrusion
Ọpụpụ plastik dabara adaba maka ihe dị iche iche nke thermoplastic, na-ekpo ọkụ na ebe mgbaze ha na-enweghị mmebi okpomọkụ. The extrusion okpomọkụ dịgasị iche dabere na kpọmkwem plastic. Plastic extrusion nkịtị gụnyere:
Polyethylene (PE): Na-apụ apụ n'etiti 400 ° C (njupụta dị ala) na 600 ° C (njupụta dị elu).
Polystyrene (PS): ~450°C
Naịlọn: 450°C ruo 520°C
Polypropylene (PP): ~ 450 Celsius
PVC: N'etiti 350C na 380C
N'ọnọdụ ụfọdụ, elastomers ma ọ bụ plastik thermosetting nwere ike ịpụpụ kama ikpochapụ thermoplastics.
Ngwa nke Extrusion Plastic
Ụlọ ọrụ extrusion plastik nwere ike ịmepụta akụkụ dị iche iche nke nwere profaịlụ na-agbanwe agbanwe. Profaịlụ extrusion plastik dị mma maka ọkpọkọ, profaịlụ ọnụ ụzọ, akụkụ ụgbọ ala, na ndị ọzọ.
1. Ọkụ na tubing
Ọkpụkpọ rọba na tubing, nke a na-emekarị site na PVC ma ọ bụ thermoplastics ndị ọzọ, bụ ngwa extrusion plastik nkịtị n'ihi profaịlụ cylindrical ha dị mfe. Otu ihe atụ bụ extruded drainage ọkpọkọ.
2. Ihe mkpuchi waya
Ọtụtụ thermoplastics na-enye ihe mkpuchi ọkụ eletrik dị mma na nkwụsi ike nke okpomọkụ, na-eme ka ha dị mma maka ikpochapụ ihe mkpuchi na mkpuchi maka wires na eriri. A na-ejikwa fluoropolymer maka nke a.
3. Profaịlụ ọnụ ụzọ na windo
Ọnụ ụzọ rọba na okpokolo agba windo, nke profaịlụ ha na-aga n'ihu na ogologo, mara mma maka extrusion. PVC bụ ihe a ma ama maka ngwa a na ngwa ụlọ ndị ọzọ metụtara profaịlụ extrusion plastik.
4. Ndị ìsì
Ndị ìsì, nke nwere ọtụtụ slats yiri ya, nwere ike ịpụpụ na thermoplastics. Profaịlụ na-adịkarị mkpụmkpụ, mgbe ụfọdụ na-enwe otu akụkụ gburugburu. A na-ejikarị polystyrene eme ihe mkpuchi osisi faux.
5. Mwepu ihu igwe
Ụlọ ọrụ extrusion plastik na-emepụtakarị ngwaahịa na-ewepụ ihu igwe, nke emebere ka ọ dabara nke ọma n'akụkụ ọnụ ụzọ na windo. Rubber bụ ihe a na-ejikarị eme ihe maka iwepụ ihu igwe.
6. Ndị na-ehichapụ windo na squeegees
A na-anyụchapụ ihe mkpofu ikuku ụgbọ ala. Plastic extruded nwere ike ịbụ ihe rọba sịntetị dị ka EPDM, ma ọ bụ ngwakọta nke sịntetik na roba eke. Mpempe akwụkwọ squeegee ejiri aka na-arụ ọrụ yiri nke mkpuchi ikuku.
Plastic Extrusion vs. Aluminom extrusion
E wezụga thermoplastics, aluminom nwekwara ike ịpụpụta iji mepụta akụkụ profaịlụ na-aga n'ihu. Uru nke extrusion aluminom gụnyere fechaa, conductivity, na recycability. Ngwa ndị a na-ahụkarị maka extrusion aluminom gụnyere mmanya, ọkpọkọ, wires, ọkpọkọ, ngere, okporo ígwè, okpokolo agba, na ebe ikpo ọkụ.
N'adịghị ka extrusion plastik, aluminom extrusion nwere ike ịdị ọkụ ma ọ bụ oyi: a na-eme ihe ọkụ ọkụ n'etiti 350 ° C na 500 Celsius C, ebe a na-eme extrusion oyi na ụlọ okpomọkụ.
Mmechi
Mbupu plastik, ọkachasị n'ọnọdụ nke China Plastic Pipe Extrusion Line, bụ ụzọ dị mma ma dịkwa mma maka imepụta akụkụ profaịlụ na-aga n'ihu. Ikike ya ijikwa ụdị thermoplastics dị iche iche na ngwa ya dị ukwuu na-eme ka ọ dị mkpa na ụlọ ọrụ mmepụta plastik.
