Rusange rusange ya plastike yububiko
Igishushanyo mbonera cya plastikibyashoboraga kugaragara nka polymersmasterbatch.Polimeri irashobora gukorwa muburyo butandukanye bwa 'mers' igereranya ibice byimiti.Ibice byinshi bya chimique biva mumavuta cyangwa hydrocarbone.Hydrocarbone nkiyo igaragara, ikozwe muri hydrogen na karubone.Noneho, plastiki ikozwe muri (cyane cyane) hydrogène na karubone byakusanyirijwe hamwe kugirango bibe mers (nka Ethylene cyangwa propylene) hanyuma izo mers zihuza gukora iminyururu kandi iyo iyo minyururu iba ndende bihagije kugirango ibe 'poly' mubisanzwe mugihe byibuze 100 ya mers yahujije hamwe, tubona kugira ibikoresho bya plastiki / polymeric.
Igishushanyo mbonera cya plastikini umuryango wa thermoplastique ugizwe na molekile ndende igizwe ahanini na karubone na hydrogen bita polymers.Ijambo rihuza "poly" ryerekeza kuri benshi na "mer" ryerekeza kuri molekile imwe isubiramo ibice biboheshejwe hamwe.Ibigize mer byubwoko butandukanye bwa plastiki, imbaraga zumubumbe wa molekuline zifata mers hamwe nuburebure bwurunigi rwa polymer nicyo kintu cyambere kigena ibintu bya plastiki.Plastike zimwe zisimburana zirenze ubwoko bumwe bwa mer ibice.
Amashanyarazimasterbatchyumuryango wa thermoset mugihe usa nuwasobanuwe haruguru bafite isano itandukanye hagati ya mers harimo kwambukiranya ibaha imitungo itandukanye harimo no mubihe bizaza ubushobozi bwo hejuru bwubushyuhe no kudashobora gushonga mbere yo kubora uko ubushyuhe bwiyongera.
Kumena igikoresho cya plastiki
Byinshiigikoresho cya plastikiiracitse!
Amashanyarazi yamashanyarazi muri rusange.Ariko si wenyine.
Hano hari amatsinda menshi ya thermoplastique akomoka kubintu bibisi byitwa Ethylene.Kandi Ethylene ikorwa muburyo butandukanye, cyane cyane biva mumavuta cyangwa gaze.
Bumwe mu buryo buzwi cyane ni ugushira ibiryo mumashanyarazi hanyuma bikavamo Ethylene, wongeyeho nibindi bintu nabyo.Ethylene noneho ihindurwamo polyethylene cyangwa polypropilene cyane ariko ntabwo yihariye.PVC, PS, PET, butadiene nayo ikozwe.
Dore igice cyakuwe mu ngingo gisobanura koigikoresho cya plastikibyiza cyane:
"Ethylene niyo ntangiriro y'ibicuruzwa bine bikuze bikuze cyane: polyethylene (ubwoko butatu: LDPE, LLDPE, na HDPE), okiside ya Ethylene, dichloride ya Ethylene (ibanziriza vinyl chloride monomer), na Ethylbenzene (ibanziriza styrene).Ubunini buke, ibicuruzwa byihariye birimo umurongo α-olefine, vinyl acetate monomer, na Ethanol ya syntetique, n'ibindi. ”
Ibikurikira nurutonde rwa Ethylene izwi cyanemasterbatchibicuruzwa:
| PVA Poly (vinyl acetate), poly (inzoga ya vinyl) | PET Poly (Ethylene terephthalate) |
| PVC Poly (vinyl chloride) | PS Polystirene |
| LLDPE Umurongo muto-wuzuye polyethylene | PEG Poly (Ethylene glycol) |
| LDPE Polyethylene nkeya | HDPE Polyethylene yuzuye |
Kugeza ubu inzira yiganjemo inganda zerekeza kuri Ethylene ni ugukata ibyuka bya gazi (Ethane, propane, cyangwa butane) cyangwa ibiryo byamazi (naphtha cyangwa amavuta ya gaze).Ku bushyuhe buri hejuru cyane ko kuva kuri dogere selisiyusi 850 cyangwa hejuru yayo, ibyo byiciro bya sisitemu yo gukanika imashini itari catalitike yarakoreshejwe.Ethylene nigicuruzwa cyagenewe;ariko izindi nyubako zifite agaciro-zubaka-nka molekile, nka propylene, butadiene, na benzene, hamwe.
Umusaruro wa buri kopi ni umurimo wibiryo byakoreshejwe.Kumena Ethane itanga hafi ya koproducts;ariko kumena naphtha bitanga urugero rwinshi rwa propylene, butadiene, na benzene.Nkuko bigaragara nko kwisi yose, kumeneka bishobora kugaragara nkimwe mubikoresho byingenzi bya butadiene, propylene hamwe nubutunzi buyobora benzene.Ishusho ikurikira irerekana igishushanyo mbonera cyuruhererekane rwimashini ikora yamashanyarazi muburyo bworoshye.
