I-SIS(i-Styrene-isoprene-styrene block copolymer)
I-Baling Petrochemical SIS iyi-styrene – isoprene block copolymer esesimweni sezinhlayiya ezimhlophe ezimbotshana noma i-translucent compact particle, enezici ze-thermo-plasticity enhle, ukunwebeka okuphezulu, ukuncibilika okuhle kokuncibilika, ukuhambisana okuhle ne-tackifying resin, ephephile futhi engenabuthi.Ingasetshenziswa ezintweni ezinamathelayo ezizwela ukucindezela okushisayo, osimende abancibilikayo, amapuleti okuphrinta aguquguqukayo, amapulasitiki kanye nokuguqulwa kwe-asphalt, futhi iyimpahla efanelekile yokunamathisela esetshenziselwa ukwakha izikhwama zokupakisha, izinto zokukhucululwa kwendle, amateyipu okunamathela anezinhlangothi ezimbili namalebula. .
IZIMPAHLA KANYE NEZINCELO
Ama-Styrene-isoprene block copolymers (SIS) angumthamo omkhulu, ama-thermoplastic elastomers (TPE) anenani eliphansi akhiqizwa yi-ionic copolymerization ephilayo ngokwethula ngokulandelana i-styrene, i-2-methyl-1,3-butadiene (isoprene), kanye ne-styrene ku-reactor. .Okuqukethwe kwe-styrene ngokuvamile kuyahluka phakathi kwamaphesenti angu-15 nama-40.Uma epholile ngaphansi kwendawo yokuncibilika, ama-SIS anokuqukethwe okuphansi kwe-styrene ngesigaba-ahlukaniselwe kuma-nano-usayizi we-polystyrene matrix afakwe ku-matrix ye-isoprene kuyilapho ukwanda kokuqukethwe kwe-styrene kuholela ku-cylindrical bese kuba nezakhiwo ze-lamellar.Izizinda ze-styrene eziqinile zisebenza njengama-crosslinks angokwenyama anikeza amandla omshini futhi athuthukise ukumelana nokuhuzuka, kuyilapho i-matrix yerabha ye-isoprene inikeza ukuguquguquka nokuqina.Izici zomshini zama-SIS elastomers anokuqukethwe okuphansi kwe-styrene zifana nalezo zamarabha abilisiwe.Kodwa-ke, ngokungafani nerabha eshibhile, ama-elastomer e-SIS angacutshungulwa ngemishini esetshenziselwa ukwenza amapholymer ashisayo.
Ama-SIS block copolymers avame ukuhlanganiswa nama-tackifier resins, uwoyela nezihlungi, okuvumela ukuguqulwa okuhlukahlukene kwezakhiwo zomkhiqizo noma zengezwe kwamanye ama-polymer ashisayo ukuze kuthuthukiswe ukusebenza kwawo.
Ama-SIS copolymers asetshenziswa kakhulu ezintweni zokunamathisela ezishisayo, ama-sealant, izinto ze-gasket, amabhande enjoloba, imikhiqizo yamathoyizi, amasoli ezicathulo nasemikhiqizweni yebitumen yokugandaywa komgwaqo nokufaka uphahla.Zibuye zisetshenziswe njengezilungisi zomthelela kanye neziqinisayo kumapulasitiki kanye nezinamatheliso (zesakhiwo).
