Kedu ụdị ihe nkiri plastik?

Ihe nkiri kacha gbasaa

Ihe nkiri polyethylene bụ ụdị ihe nkiri plastik a na-ejikarị eme ihe, na-aza ihe karịrị 40% nke mkpokọta ihe nkiri plastik. Ụdị isi na njirimara nke ihe nkiri polyethylene:

1. Ihe nkiri Polyethylene dị obere (LDPE)

Ihe nkiri LDPE bụ mgbanwe ha, nghọta ha, na ndị na-adịghị egbu egbu, enweghị isi. Ha nwere ezigbo nguzogide mmiri, mkpuchi mmiri, na nkwụsi ike kemịkalụ, na-eme ka ha dabara maka ịkwakọ ngwaahịa nri, ọgwụ na ngwaahịa ndị a na-eji kwa ụbọchị. Ihe nkiri LDPE nwekwara ezigbo ihe mkpuchi ọkụ ma na-ejikarị ya dị ka mkpuchi mkpuchi okpomọkụ na ihe nkiri mejupụtara. Otú ọ dị, ha anaghị eguzogide okpomọkụ na-adịghị mma ma ọ dịghị mma maka nkwakọ nri okpomọkụ dị elu.

2. Ihe nkiri Polyethylene dị elu (HDPE)

Ihe nkiri HDPE siri ike, ọkara translucent, na agba ọcha. Ha na-egosipụta ike ike dị elu, nguzogide mmiri, nguzogide okpomọkụ, na nguzogide mmanụ ma e jiri ya tụnyere LDPE. HDPE dabara adaba maka nkwakọ ngwaahịa na-adịgide adịgide na ihe nkiri ụlọ ọrụ mana ọ nwere obere nghọta na gloss.

3. Ihe nkiri Polyethylene dị ala dị ala (LLDPE)

Ihe nkiri LLDPE na-ejikọta mgbanwe nke LDPE na ike nke HDPE, na-enye ihe ndọtị dị mma na nkwụsi ike. A na-eji ha eme ihe n'ọtụtụ ebe na fim gbatịa, ihe nkiri na-ebelata, na ihe nkiri mkpuchi, na-eme ka ha dị mma maka nkwakọ ngwaahịa ngwa ngwa ngwa ngwa.

4. Metallocene Linear Low-Density Polyethylene Film (mLLDPE)

A na-emepụta ihe nkiri mLLDPE site na iji metallocene catalysts ma na-enye ike mmetụta dị elu, ike ịmị mkpụrụ, na nghọta ka mma ma e jiri ya tụnyere LLDPE nkịtị. Ha na-enye ohere maka ibelata ọkpụrụkpụ ihe nkiri ihe karịrị 15%, si otú a na-ebelata ọnụ ahịa ihe onwunwe. A na-ejikarị mLLDPE eme ihe na fim griin haus, ihe nkiri nkwakọ ngwaahịa dị arọ, ihe nkiri na-ebelata, na ihe nkwakọ ngwaahịa dị elu.

Ihe nkiri plastik ndị ọzọ

1. Polypropylene (PP) Ihe nkiri: Ihe a ma ama maka ebe mgbaze ha dị elu (160-170 ° C), na-eme ka ha dị mma maka ngwa ọkụ na-ekpo ọkụ na nkwakọ ngwaahịa ngwa ndakwa nri. Ihe nkiri PP na-enye ezigbo nguzogide kemịkalụ ma a na-ejikarị ya eme ihe maka nkwakọ nri nri nri na ihe mkpuchi ngwa ngwa ọgwụ.

2. Ihe nkiri Polyvinyl Chloride (PVC): Bara uru maka nchapụta pụrụ iche na ibipụta mana ọ na-eche ihu mbelata ojiji n'ihi nchegbu gburugburu ebe obibi. Ngwa fọdụrụnụ gụnyere ngwugwu ọnya na ụfọdụ ihe nkiri nri5.

3. Polyester (PET) Ihe nkiri: Na-anya isi ike dị elu na nkwụsi ike nke okpomọkụ, ihe nkiri PET dị mkpa maka ngwá electronic na-agbanwe agbanwe, teepu magnetik, na nkwakọ ngwaahịa ihe mgbochi dị elu. Biaxial-oriented PET (BOPET) na-egosipụta nke ọma n'ịrụ ọrụ na ihe mgbochi.

Ihe nkiri polymer pụrụ iche:

1. Polyamide (Nylon): Ihe mgbochi oxygen pụrụ iche maka nchekwa nri

2. Polyvinylidene Chloride (PVDC): Mmiri dị egwu na arụ ọrụ mgbochi oxygen

3. Polylactic Acid (PLA): Nhọrọ ọzọ dabere na bio na compostability, ọ bụ ezie na ọdịnala na-ejedebe site na brittleness-ọganihu ndị na-adịbeghị anya emepụtala ihe nkiri PLA na-agbanwe agbanwe site na itinye polyether plasticizers ozugbo na yinye polymer.

Ụzọ mmepụta ihe nkiri plastik

1. Blown Film Extrusion: The na-achị usoro maka PE film, ebe gbazee polymer na-extruded site a okirikiri anwụ anwụ, inflated n'ime a afụ, na mma na-etolite a tube na ike gbawara n'ime abụọ-layer film. Usoro a na-enye ihe eji arụ ọrụ n'ụzọ ziri ezi na ma igwe ma n'ụzọ ntụgharị.

2. Nkedo ihe nkiri extrusion: Polymer gbazee na-extruded site a flat die na chilled mpịakọta, na-emepụta fim na ahụkebe doo anya na edo ọkpụrụkpụ. A na-ahụkarị maka ihe nkiri PP na PET ebe akụrụngwa anya dị oke mkpa.

3. Calendering: A na-ejikarị eme ihe maka ihe nkiri PVC, ebe a na-agafe ogige polymer site na usoro nke rollers na-ekpo ọkụ iji nweta njikwa nha nha. Ihe nkiri kalenda na-enwekarị mmecha elu dị elu mana ihe eji arụ ọrụ enweghị otu n'ofe obosara.

4. Ngwọta nkedo: A na-eji ihe nkiri pụrụ iche ebe oke nha anya ma ọ bụ mmetụta okpomọkụ na-egbochi nhazi agbaze. A na-agbaze polymer ahụ ka ọ bụrụ ihe mgbaze, tụba ya na eriri, wee kpoo ya ka ọ bụrụ ihe nkiri - nke a na-ahụkarị maka ụfọdụ ihe nkiri na ngwa akpụkpọ anụ.

5. Biaxial Orientation: A na-agbatị ihe nkiri na ma igwe na ntụgharị ntụgharị, ma ọ bụ n'usoro (tenter frame) ma ọ bụ n'otu oge (usoro afụ), na-eme ka ike dị ike, doo anya na ihe mgbochi. Ihe nkiri Biaxial-oriented PP (BOPP) na PET (BOPET) bụ ụkpụrụ ụlọ ọrụ maka nkwakọ ngwaahịa dị elu.

Usoro na-apụta na ihe ọhụrụ na ihe nkiri plastik

Ụlọ ọrụ ihe nkiri plastik na-agbanwe agbanwe, na-emesi ike na nkwado, arụmọrụ, na arụmọrụ. Usoro ụfọdụ ama ama gụnyere:

1.Ndị nnọchi anya PFAS na-akwụghị ụgwọ:Ihe na-adịgide adịgide na-ezere per- na polyfluoroalkyl bekee (PFAS), na-egbo mkpa arụmọrụ yana nchegbu gburugburu ebe obibi.

2. Initiatives Sustainability Initiatives: Companieslọ ọrụ dị ka Fox Packaging ewepụla PFAS nke ọma na nhọrọ nkwakọ ngwaahịa ha niile na-agbanwe agbanwe, na-ekwekọ n'usoro iwu sara mbara na usoro ụlọ ọrụ. US FDA echekwala nkwa afọ ofufo iji wepụ PFAS na nkwakọ nri, na-enye aka na mbelata dị ukwuu na mkpughe PFAS nri.

Ngwọta ohuru maka nhazi PFAS-free na-enyere ihe nkiri plastik sitere na SILIKE

SILIKE na-eji ngwa ahịa usoro SILIMER na-eme ihe, na-enye ihe ọhụrụIhe enyemaka nhazi polymer na-enweghị PFAS (PPAs).
