1. Okwu mmalite
Polystyrene (PS) bụ polymer thermoplastic bara ụba na nke bara uru nke a na-ejikarị na nkwakọ ngwaahịa, ngwa ahịa na ihe owuwu. Dị n'ụdị abụọ bụ isi — General Purpose Polystyrene (GPPS, crystal clear) na High Impact Polystyrene (HIPS, na rọba siri ike)—PS na-eji ya akpọrọ ihe maka nkwụsi ike ya, ịdị mfe nhazi ya na ike ya. Edemede a na-enyocha njirimara PS plastic, ngwa isi, ụzọ nhazi, na echiche ahịa.
2. Njirimara nke Polystyrene (PS)
PS na-enye njirimara dị iche iche dabere n'ụdị ya:
A. Ebumnuche izugbe Polystyrene (GPPS)
- Nchapụta anya - Ntugharị, ọdịdị yiri iko.
- Nkwụsi ike & Nkịta - siri ike mana ọ na-enwekarị mgbawa n'okpuru nrụgide.
- Dị arọ - Njupụta dị ala (~ 1.04-1.06 g/cm³).
- Igwe ọkụ eletrik - Ejiri ya na ngwa eletrọnịkị na ihe ndị a pụrụ ịtụfu ya.
- Nguzogide kemịkalụ - Na-eguzogide mmiri, acids na alkalis mana ọ na-agbaze na ihe mgbaze dị ka acetone.
B. Polystyrene mmetụta dị elu (HIPS)
- Ihe siri ike emelitere - Nwere 5-10% polybutadiene roba maka nguzogide mmetụta.
- Ọdịdị na-adịghị ahụkebe - Obere ụzọ karịa GPPS.
- Thermoforming dị mfe - Ọ dị mma maka nkwakọ nri na arịa enwere ike iwepụ.
3. Ngwa igodo nke PS Plastic
A. Ụlọ ọrụ nkwakọ ngwaahịa
- Nri nri (iko a na-atụfu ihe, clamshells, cutlery)
- Okwu CD & DVD
- Foam Nchekwa (EPS - Polystyrene gbasaa) - Ejiri ya na nkwakọ ngwaahịa ahụekere na mkpuchi.
B. Ngwaahịa ndị ahịa
- Ihe ụmụaka ji egwuri egwu na ihe eji ede akwụkwọ (brik dị ka LEGO, mkpịrị mkpịsị akwụkwọ)
- Ihe ịchọ mma (akpa kọmpat, tubes lipstick)
C. Eletrọnịkị & Ngwa
- Igwe nju oyi
- Mkpuchi Ngosipụta Ngosipụta (GPPS)
D. Mwube & mkpuchi
- EPS Foam Board (ihe mkpuchi ụlọ, ihe dị arọ)
- Ihe eji achọ mma
4. Usoro nhazi maka PS Plastic
Enwere ike ịmepụta PS site na iji usoro dị iche iche:
- Ịkpụzi ịgba ọgwụ mgbochi (nke a na-ahụkarị maka ngwaahịa ndị siri ike dị ka ihe na-egbu egbu)
- Extrusion (maka mpempe akwụkwọ, ihe nkiri na profaịlụ)
- Thermoforming (Eji ya na nkwakọ nri)
- Mkpụzi ụfụfụ (EPS) - PS gbasaara maka mkpuchi na ịkwanye.
5. Usoro ahịa na ihe ịma aka (2025 Outlook)
A. Ịdịgide & Nrụgide Usoro
- Mmachibido iwu na PS naanị otu – Ọtụtụ mba na-amachibido ngwaahịa PS enwere ike ịtụfu ya (dịka ọmụmaatụ, ntuziaka otu eji plastik eme otu EU).
- PS emegharịrị & Bio-Dabere - Ọchịchọ na-eto eto maka usoro enyi na enyi gburugburu ebe obibi.
B. Asọmpi sitere na Plastic Alternative
- Polypropylene (PP) - Na-eguzogide okpomọkụ na-adịgide adịgide maka nkwakọ nri.
- PET & PLA - A na-eji ya na nkwakọ ngwaahịa nwere ike imegharị/na-emebi emebi.
C. Regional Market Dynamics
- Asia-Pacific (China, India) na-achịkwa mmepụta na oriri PS.
- North America na Europe lekwasịrị anya na imegharị ihe na mkpuchi EPS.
- Middle East na-etinye ego na mmepụta PS n'ihi ọnụ ahịa nri dị ala.
6. Nkwubi okwu
Polystyrene ka bụ isi rọba na nkwakọ ngwaahịa na ngwa ahịa n'ihi ọnụ ala ya na ịdị mfe nhazi ya. Otú ọ dị, nchegbu gburugburu ebe obibi na mmachibido iwu nke PS na-eme otu ihe na-eme ka ihe ọhụrụ dị n'imegharị na ihe ndị ọzọ dabere na bio. Ndị na-emepụta ihe na-emegharị na ụdị akụ na ụba okirikiri ga-akwado uto n'ahịa rọba na-agbanwe.
