Styrene no kuyikoresha

Styrene ni iki

Styrene nigikoresho cyingenzi cyibikoresho ngengabuzima, imiti yacyo ni C8H8, yaka umuriro, imiti iteje akaga, ikomoka kuri benzene yuzuye na synthesis ya Ethylene.Ikoreshwa cyane cyane mu gukora ifuro rya polystirene (EPS), polystirene (PS), ABS hamwe n’ibindi bikoresho bya sintetike hamwe na reberi ya styrene butadiene (SBR), SBS elastomer, ibicuruzwa byo hasi bikoreshwa cyane mu kubaka insulation, gukora imodoka, ibikoresho byo mu rugo, gukora ibikinisho, imyenda, impapuro, gupakira inkweto nizindi nganda.Mubyongeyeho, irashobora kandi gukoreshwa nkimiti, imiti yica udukoko, irangi, abahuza imyunyu ngugu, ifite uburyo bwinshi bwo gukoresha.Ibikomoka kuri styrene ni ibikomoka kuri LARGEST ya kane ya Ethylene nyuma ya polyethylene, okiside ya Ethylene na vinyl chloride, kandi umusaruro wa styrene ni uwa kabiri nyuma ya polyethylene (PE) na chloride polyvinyl (PVC).

1. Urunigi rw'inganda

Ibiranga urunigi rwa styrene rushobora kuvugwa muri make nk '"amavuta yo hejuru hamwe n’amakara, rebero yo hasi" - urwego rwo hejuru rukora inganda zikomoka kuri peteroli hamwe n’inganda zikora amakara y’amakara, munsi y’inganda zikoreshwa mu nganda.

2. Koresha

Muburyo bwo hejuru bwa styrene kuri Ethylene na benzene isukuye, hepfo ya styrene, EPS ifuro polystirene, acrylonitrile - butadiene - styrene terpolymer, SBR / SBL styrene butadiene reberi, styrene latex ikwirakwiza hasi.EPS, ABS na PS nicyo kinini kinini cyo hasi cya styrene, kibarirwa hejuru ya 70%.Usibye iki gice cyibisabwa hasi, styrene ikoreshwa no muri farumasi, irangi, imiti yica udukoko, gutunganya amabuye y'agaciro nizindi nganda.

EPS ifuro polystirene ikozwe muri styrene na fonction agent yongeweho ibicuruzwa, ifite ubucucike bugereranije bwumuriro muto, ubushyuhe buke bwumuriro, kwinjiza amazi make, guhinda umushyitsi, kubika ubushyuhe, kubika amajwi, kutagira amazi, kurwanya vibrasiya, imikorere ya dielectric nibyiza gutegereza kubwinyungu, ikoreshwa cyane mubwubatsi bwibikoresho, ibikoresho byamashanyarazi / ibikoresho byo mu biro ibikoresho byo gupakira hamwe nigikombe kimwe cyo kunywa / agasanduku, nibindi.

PS polystirene ikoreshwa cyane mu nganda zoroheje, cyane cyane mu gushushanya buri munsi, kwerekana amatara no gupakira ibicuruzwa.Byongeye kandi, polystirene nigikoresho cyiza cyane cyo kubika amashanyarazi, kuburyo gishobora no gukoreshwa mugukora ibikoresho bitandukanye byibikoresho, ibikoresho byifashishwa nibitangazamakuru.

ABS resin ikozwe muri styrene, acrylonitrile, butadiene terpolymer, ifite imbaraga zo guhangana ningaruka nziza, imiti irwanya imiti hamwe n’amashanyarazi, ni ibikoresho byiza cyane, bikoreshwa cyane mubikoresho byo murugo / ibikoresho byo mu biro shell hamwe nibindi bikoresho, ikibaho cyimodoka / umuryango / fender.
