Kedu ihe dị iche n'etiti ịkpụzi injection na ịfụ ụfụ?

1. Usoro nke ịkpụzi injection na ịkpụzi ihe dị iche.Ịkpụ afụ bụ ịgba ntụtụ + ịfụ;ịkpụzi injection bụ injection + nrụgide;Ịkpụ afụ ga-abụrịrị ọkpọkọ na-afụ ahụ hapụrụ isi, na ịkpụzi injection ga-enwerịrị ngalaba Gate

2. N'ikwu okwu n'ozuzu, ịkpụzi injection bụ ahụ siri ike, ịfụ ụfụ bụ isi ahụ nwere oghere, na ọdịdị nke ịkpụzi ihe na-adịghị mma.Ịkpụzi ihe ọkụkụ nwere ọdụ ụgbọ mmiri na-afụ.

3. Ịkpụzi injection, ya bụ, thermoplastic injection molding, nke a na-agbaze ihe plastik wee gbanye n'ime oghere ihe nkiri ahụ.Ozugbo rọba a wụrụ awụ batara n'akpụkpọ ahụ, a na-eme ka ọ dị mma ka ọ bụrụ ọdịdị oghere.Ụdị a na-esi na ya pụta na-abụkarị ngwaahịa ikpeazụ na ọ dịghị nhazi ọzọ achọrọ tupu akụrụngwa ma ọ bụ jiri dị ka ngwaahịa ikpeazụ.Enwere ike ịmepụta ọtụtụ nkọwa, dị ka ndị isi, ọgịrịga, na eri, n'otu ọrụ ịkpụzi injection.Igwe na-akpụzi ihe ntụtụ nwere ihe abụọ bụ isi: ngwaọrụ injection nke na-agbaze ma na-enye rọba ahụ n'ime ihe a na-akpụ, na ihe nkedo.Mmetụta nke akụrụngwa ebu bụ:

1) A na-emechi ihe ọkpụkpụ n'okpuru ọnọdụ nke ịnweta nrụgide injection;

2) Wepụ ngwaahịa ahụ n'ime ngwa injection ahụ iji gbazee plastik tupu etinye ya n'ime ihe ahụ, wee chịkwaa nrụgide na ọsọ iji gbanye agbaze n'ime ihe.Enwere ụdị ihe ntụtụ abụọ a na-eji taa: screw pre-plasticizer ma ọ bụ ngwa abụọ, na screw reciprocating.Ndị na-ahụ maka screw pre-plasticizers na-eji screw pre-plasticizing (ogbo nke mbụ) iji tinye rọba a wụrụ awụ n'ime mkpanaka injection (ogbo nke abụọ).Uru nke screw pre-plasticizer bụ ịdị mma gbazee, nrụgide dị elu na ọsọ dị elu, yana njikwa olu ịgbanye kpọmkwem (iji ngwaọrụ ntinye igwe na nsọtụ abụọ nke strok piston).

A na-achọrọ uru ndị a maka ngwaahịa doro anya, nke nwere mgbidi dị mkpa na ọnụego mmepụta dị elu.Ọdịmma gụnyere oge obibi na-ezighi ezi (na-eduga na mmebi ihe onwunwe), ọnụ ahịa akụrụngwa dị elu yana ụgwọ mmezi.Ngwa ntụtụ na-emegharị emegharị nke a na-ejikarị eme ihe anaghị achọ ihe mgbaze ka ọ gbazee na igba rọba.

Ịkpụzi afụ: nke a makwaara dị ka ịkpụzi ihe oghere, ịkpụzi ihe, usoro nhazi rọba na-eto ngwa ngwa.The tubular plastic parison nwetara site extrusion ma ọ bụ injection ịkpụzi nke thermoplastic resin na-etinye n'ime kewara ebu mgbe ọ na-ekpo ọkụ (ma ọ bụ kpụ ọkụ n'ọnụ na a nro ala), na abịakọrọ ikuku na-ewebata n'ime parison ozugbo emechiri ebu ka ịfụ plastic parison. .Ọ na-agbasawanye ma na-arapara n'ahụ mgbidi dị n'ime nke ebu, na mgbe ọ dị jụụ na ịkwatu, a na-enweta ngwaahịa dị iche iche oghere.The mmepụta usoro nke fụrụ afụ film yiri nnọọ na ụkpụrụ ịfụ ịkpụzi nke oghere ngwaahịa, ma ọ dịghị eji a ebu.Site n'echiche nke nhazi teknụzụ nhazi plastik, a na-etinyekarị usoro ịkpụzi ihe nkiri a na-agbapụta na extrusion.Ebu ụzọ were usoro ịkpụzi ihe a na-eme iji mepụta vial polyethylene dị obere n'oge Agha Ụwa nke Abụọ.N'ọgwụgwụ afọ 1950, mgbe a mụrụ polyethylene dị elu na mmepe nke igwe ịkpụzi ihe, a na-eji nkà ịkpụzi ihe n'ọtụtụ ebe.Ọnụ ọgụgụ nke arịa ndị nwere oghere nwere ike iru puku kwuru puku lita, ụfọdụ mmepụta anabatala njikwa kọmputa.Plastics kwesịrị ekwesị maka ịkpụzi ihe gụnyere polyethylene, polyvinyl chloride, polypropylene, polyester, wdg, na ihe ndị nwere oghere enwetara bụ nke a na-ejikarị dị ka ihe nkwakọ ngwaahịa mmepụta ihe.
