1. Intangiriro
Polystirene (PS) ni polymer itandukanye kandi ihenze cyane ya termoplastique polymer ikoreshwa cyane mubipfunyika, ibicuruzwa byabaguzi, nubwubatsi. Biboneka muburyo bubiri bwibanze-Intego rusange ya Polystirene (GPPS, kristu isobanutse) hamwe na Polystyrene Impinduka nyinshi (HIPS, ikomejwe na reberi) --PS ihabwa agaciro kubera gukomera kwayo, koroshya gutunganya, kandi birashoboka. Iyi ngingo iragaragaza imiterere ya plastike ya PS, ibyingenzi byingenzi, uburyo bwo gutunganya, nuburyo isoko ryifashe.
2. Ibyiza bya Polystirene (PS)
PS itanga ibiranga bitandukanye bitewe n'ubwoko bwayo:
A. Intego rusange Polystirene (GPPS)
- Ibyiza bisobanutse - Biragaragara, ibirahuri bisa.
- Rigidity & Brittleness - Biragoye ariko bikunda gucika munsi ya stress.
- Umucyo woroshye - Ubucucike buke (~ 1.04–1.06 g / cm³).
- Amashanyarazi - Gukoresha ibikoresho bya elegitoroniki nibintu bikoreshwa.
- Imiti irwanya imiti - Irwanya amazi, aside, na alkalis ariko igashonga mumashanyarazi nka acetone.
B. Impinduka nyinshi Polystirene (HIPS)
- Kunoza ubukana - Harimo reberi ya polybutadiene 5-10% kugirango irwanye ingaruka.
- Kugaragara neza - Ntibisobanutse neza kuruta GPPS.
- Thermoforming yoroshye - Nibyiza kubipfunyika ibiryo hamwe nibikoresho bikoreshwa.
3. Ibyingenzi byingenzi bya PS Plastike
A. Inganda zipakira
- Ibikoresho birimo ibiryo (ibikombe bikoreshwa, clamshells, ibikoresho)
- CD & DVD Imanza
- Kurinda ifuro (EPS - Polystirene yagutse) - Ikoreshwa mu gupakira ibishyimbo no kubika.
B. Ibicuruzwa byabaguzi
- Ibikinisho & Sitasiyo (Amatafari asa na LEGO, amakaramu)
- Ibikoresho byo kwisiga (Imyenda yoroheje, imiyoboro ya lipstick)
C. Ibyuma bya elegitoroniki n'ibikoresho
- Firigo
- Kwerekana neza (GPPS)
D. Ubwubatsi & Gukingira
- Ikibaho cya EPS (Kwubaka insulasi, beto yoroheje)
- Ibishushanyo mbonera
4. Uburyo bwo gutunganya uburyo bwa PS Plastike
PS irashobora gukorwa hakoreshejwe uburyo bwinshi:
- Gutera inshinge (Bisanzwe kubicuruzwa bikaze nkibikoresho)
- Gukuramo (Kurupapuro, firime, na profile)
- Thermoforming (Ikoreshwa mu gupakira ibiryo)
- Gufata ifuro (EPS) - Yaguwe PS yo kubika no kwisiga.
5. Inzira yisoko & imbogamizi (2025 Outlook)
A. Kuramba & Imyitwarire igenga
- Ibibujijwe gukoreshwa rimwe PS - Ibihugu byinshi bigabanya ibicuruzwa bya PS bikoreshwa (urugero, Umuryango w’ubumwe bw’ibihugu by’Uburayi).
- Gusubiramo & Bio-ishingiye kuri PS - Kwiyongera gukenewe kubindi bidukikije byangiza ibidukikije.
B. Irushanwa riva mubindi bikoresho bya plastiki
- Polypropilene (PP) - Kurwanya ubushyuhe bwinshi kandi biramba kubipakira ibiryo.
- PET & PLA - Byakoreshejwe mubisubirwamo / biodegradable packaging.
C. Ibikorwa byisoko ryakarere
- Aziya-Pasifika (Ubushinwa, Ubuhinde) yiganje mu musaruro wa PS no gukoresha.
- Amerika y'Amajyaruguru n'Uburayi byibanda ku gutunganya no gukoresha EPS.
- Uburasirazuba bwo hagati bushora imari mu musaruro wa PS kubera ibiciro by'amatungo make.
6. Umwanzuro
Polystirene ikomeje kuba plastiki yingenzi mubipfunyika nibicuruzwa byabaguzi kubera igiciro cyayo gito kandi byoroshye gutunganya. Nyamara, impungenge z’ibidukikije hamwe n’amabwiriza agenga ikoreshwa rimwe PS biratera udushya mu gutunganya no gukoresha bio. Abahinguzi bamenyereye imiterere yubukungu buzenguruka bazakomeza iterambere ryisoko rya plastiki rigenda ryiyongera.
