SIS (Styrene-isoprene-styrene block copolymer)
Baling Petrochemical SIS waa styrene - copolymer isoprene block qaab ah qayb dalool cad ah ama qayb is haysta oo translucent ah, oo leh sifooyin heerkulbeeg wanaagsan, barti sare, dareere dhalaalid wanaagsan, waafaqid wanaagsan oo leh resin tackifying, ammaan ah oo aan sun ahayn.Waxaa lagu dabaqi karaa xabagyada xasaasiga ah ee cadaadiska kulul, shamiitada dareeraha ah, taarikada daabacaadda dabacsan, balaastikada iyo wax ka beddelka asphalt, waana alaabta ceeriin ee ugu habboon ee xabagta loo isticmaalo soo saarista bacaha wax lagu duubo, sahayda fayadhowrka, cajalado dhejisyo laba geesood ah iyo calaamado .
HANTIDA IYO CODSIGA
Styrene-isoprene block copolymers (SIS) waa mug weyn, qiimo jaban ganacsi thermoplastic elastomers (TPE) kuwaas oo ay soo saarto noolaha copolymerization ionic iyadoo si isdabajoog ah loo soo bandhigayo styrene, 2-methyl-1,3-butadiene (isoprene), iyo styrene galay reactor. .Waxa ku jira styrene caadi ahaan way kala duwan tahay inta u dhaxaysa 15 iyo 40 boqolkiiba.Marka la qaboojiyo meel ka hooseysa barta dhalaalka, SIS's oo leh waji hoose oo ka kooban styrene-ka-sooca nano-xajmiga polystyrene ee ku dhexjira matrix isoprene halka kororka maadada styrene ay horseedayso qaab-dhismeedka cylindrical ka dibna qaab-dhismeedka lamellar.Qaybaha adag ee Styrene waxay u shaqeeyaan sidii isku-goysyada jireed kuwaas oo bixiya awood farsamo waxayna hagaajiyaan caabbinta nabarka, halka matrixka isoprene ee caagga ah ay bixiso dabacsanaan iyo adag.Astaamaha makaanikada ee SIS elastomers ee leh maadada styrene hoose waxay la mid tahay kuwa caagadaha vulcanized ah.Si kastaba ha ahaatee, si ka duwan caag vulcanized ah, SIS elastomers waxaa lagu farsamayn karaa qalab loo isticmaalo soo saaridda kulbalaastigga polymers.
SIS block copolymers waxaa inta badan lagu dhex daraa resins tackifier, saliid iyo buuxinyaal, taas oo u ogolaanaysa in wax laga beddelo guryaha alaabta ama waxaa lagu daraa polymers kale oo heerkulbeeg ah si kor loogu qaado waxqabadkooda.
Copolymers SIS waxaa si weyn loogu isticmaalaa xabagta kulul, shaabadda, alaabta gaasaska, xargaha caagga ah, alaabada ay carruurtu ku ciyaarto, kabaha kabaha iyo alaabta bitumen ee loogu talagalay codsiyada saqafka waddooyinka iyo saqafka.Waxa kale oo loo isticmaalaa wax ka beddelayaasha saamaynta iyo adkaynaya caagadaha iyo dhejiska (qaabdhismeedka).
