SBS (styrene-butadiene thaiv copolymer)
PROPERTIES THIAB APPLICATIONS
Styrene-butadiene block copolymer yog cov chav kawm tseem ceeb ntawm cov roj hmab hluavtaws.Ob hom ntau tshaj plaws yog linear thiab radial triblock copolymer muaj roj hmab chaw thaiv thiab polystyrene kawg blocks.SBS elastomers muab cov khoom ntawm cov thermoplastic resins nrog cov roj hmab butadiene.Qhov nyuaj, glassy styrene blocks muab cov neeg kho tshuab lub zog thiab txhim kho kev puas tsuaj, thaum cov roj hmab nruab nrab-thaiv muab kev yooj yim thiab tawv.
Hauv ntau yam, SBS elastomers nrog cov ntsiab lus qis styrene muaj cov khoom zoo ib yam li cov roj hmab vulcanized butadiene, tab sis tuaj yeem molded thiab extruded siv cov khoom siv ua cov thermoplastic.Txawm li cas los xij, SBS tsis tshua muaj zog dua li cov tshuaj sib txuas sib txuas (vulcanized) butadiene roj hmab thiab yog li, tsis rov qab zoo li deformation li vulcanized diene elastomers.
SBS rubbers feem ntau sib xyaw nrog lwm cov polymers los txhim kho lawv cov kev ua tau zoo.Feem ntau cov roj thiab cov fillers tau ntxiv rau tus nqi qis thiab ntxiv hloov lawv cov khoom.
Daim ntawv thov
SBS tau siv ntau yam kev lag luam:automotive, bitumen hloov kho, HIPS, khau khau thiab masterbatch.Cov roj hmab hluavtaws feem ntau nyiam dua cov roj hmab ntuj vim tias nws muaj siab dua hauv purity thiab yooj yim dua los tuav.Ib qho ntawm BassTech cov khoom tseem ceeb, styrene-butadiene styrene (SBS), yog cov roj hmab hluavtaws siv hauv kev tsim khoom.
1. Styrene-butadiene styrene yog cais raws li cov thermoplastic elastomer.
Raws li cov thermoplastic elastomer, SBS tau yooj yim ua tiav thiab rov ua dua thaum cua sov.Thaum cua sov, nws ua zoo li yas thiab ua haujlwm tau zoo heev.Nws cov qauv (thaiv copolymer nrog ob txoj hlua polystyrene) tso cai rau kev sib xyaw ntawm cov yas tawv thiab elastic zog.
2. Muab piv rau cov roj hmab vulcanized tsoos, siv styrene-butadiene styrene tuaj yeem pab txo cov nqi tsim khoom.
Nws yog recyclable, puas-resistant thiab tsis xav tau vulcanizing.SBS muaj hnub nyoog zoo thiab tsis hnav yooj yim, txo qhov kev xav tau ntawm kev kho thiab ua rau nws muaj txiaj ntsig zoo ntawm cov khoom siv vov tsev.
3. Styrene-butadiene styrene yog qhov tsim nyog rau kev siv vov tsev.
SBS tau siv dav hauv kev siv vov tsev xws li kev hloov kho bitumen, cov ntaub ntawv ua kua thiab cov txheej txheem dej tsis zoo.Nyob rau hauv qhov txias txias, SBS tseem muaj zog, hloov tau thiab tiv taus noo noo.Ntxiv nrog rau cov vov tsev, SBS yog siv rau hauv paving, sealants thiab coatings ntxiv rau qhov txias txias thiab txo qhov kev puas tsuaj tawg.Raws li kev hloov kho asphalt, SBS tiv thaiv cov pob qhov thiab cov kab nrib pleb feem ntau tshwm sim los ntawm thermal shock.
4. Styrene-butadiene styrene yog cov khoom siv nrov rau cov tuam txhab khau.
SBS yog ib qho khoom siv zoo heev hauv kev tsim khau rau ntau qhov laj thawj uas ua rau nws zoo tagnrho rau vov tsev.Hauv cov khau khau, styrene-butadiene styrene pab txhawb rau cov khoom muaj zog thiab hloov tau yooj yim uas tuaj yeem ua kom tsis muaj dej.
