SIS (Styrene-isoprene-styrene block copolymer)
Baling Petrochemical SIS ni styrene - isoprene block copolymer muburyo bwa porojeri yera cyangwa ibice byoroheje byoroheje, hamwe nibiranga ibintu byiza bya termo-plastike, ibintu byoroshye cyane, amazi meza ashonga, guhuza neza no guhangana na resin, umutekano kandi udafite uburozi.Irashobora gukoreshwa kumashanyarazi ashyushye yunvikana, sima ya solvent, plaque zicapura byoroshye, plastike no guhindura asifalt, kandi nibikoresho byiza bibisi byamavuta akoreshwa mugukora imifuka ipakira, ibikoresho by'isuku, kaseti zifata impande zombi hamwe na labels .
UMUTUNGO N'UBUSABWA
Styrene-isoprene block copolymers (SIS) nubunini bunini, igiciro gito cyubucuruzi bwa thermoplastique elastomers (TPE) ikorwa nubuzima bwa ionic copolymerisation ikoresheje styrene, 2-methyl-1,3-butadiene (isoprene), na styrene muri reaktor .Ibiri muri styrene mubisanzwe biratandukanye hagati ya 15 na 40%.Iyo ikonje munsi yo gushonga, SIS ifite stirene nkeya yibice-bitandukanijwe mubice bya nano-nini ya polystirene yinjijwe muri matrise ya isoprene mugihe iyongerekana ryibintu bya styrene riganisha kuri silindrike hanyuma ikubaka imiterere ya lamellar.Imiterere ikomeye ya styrene ikora nkimikorere ihuza umubiri itanga imbaraga zumukanishi kandi igateza imbere kurwanya abrasion, mugihe matrike ya isoprene reberi itanga guhinduka no gukomera.Imiterere yubukorikori bwa SIS elastomers ifite styrene nkeya isa niy'ibikoresho bya rubber.Ariko, bitandukanye na reberi yibirunga, SIS elastomers irashobora gutunganywa nibikoresho bikoreshwa muguhimba polimoplastique.
SIS ihagarika kopolymers ikunze kuvangwa na tackifier resin, amavuta hamwe nuwuzuza, ibyo bikaba bituma habaho guhindura ibintu byinshi mubicuruzwa cyangwa byongewe kubindi bikoresho bya polimoplastike kugirango bongere imikorere yabo.
SIS copolymers ikoreshwa cyane mubikoresho bishyushye, bifunga kashe, ibikoresho bya gaze, amabuye ya reberi, ibikinisho, inkweto zinkweto ndetse nibicuruzwa bya bitumen byo gutunganya umuhanda no gusakara ibisenge.Zikoreshwa kandi nk'impinduka zoguhindura hamwe no gukomera muri plastiki hamwe na (imiterere).
