Qeexida SBS ee la beddelay iyo taariikhdeeda horumarineed
Waqtiga Siideynta:2024-06-20
Daamurka SBS ee wax laga beddelay waxa uu u isticmaalaa asphalt-ka salka wax ceeriin ah, waxa uu ku daraa qayb ka mid ah beddelka SBS, oo waxa uu isticmaalaa xiiraya, walaaqaya iyo habab kale si uu si siman SBS ugu kala firdhiyo daamurka. Isla mar ahaantaana, qayb gaar ah oo xasiliye gaar ah ayaa lagu daraa si loo sameeyo isku dhafka SBS. qalab, iyadoo la isticmaalayo sifooyinka wanaagsan ee SBS si loo beddelo asphalt.
Isticmaalka wax ka beddelayaasha si wax looga beddelo asphalt waxay leedahay taariikh dheer oo caalami ah. Bartamihii qarnigii 19-aad, habka vulcanization-ka ayaa la isticmaalay si loo yareeyo dhexgalka asphalt iyo kordhinta barta jilicsan. Kobcinta daamurka wax laga beddelay 50kii sano ee la soo dhaafay ayaa qiyaas ahaan soo martay afar marxaladood.
(1) 1950-1960, si toos ah ugu qas budada caagga ah ama cinjirka daamurka, si siman u walaaq oo isticmaal;
(2) Laga soo bilaabo 1960 ilaa 1970, styrene-butadiene caag synthetic ah ayaa la isku daray waxaana loo adeegsaday goobta dhexdeeda qaab cinjir ah oo saami ahaan ah;
(3) Laga soo bilaabo 1971 ilaa 1988, marka lagu daro codsiga joogtada ah ee caag synthetic, resins thermoplastic ayaa si ballaaran loo isticmaalay;
(4) Ilaa 1988, SBS waxay si tartiib tartiib ah u noqotay walaxda wax laga beddelay.
Taariikh kooban oo ku saabsan horumarka SBS oo la beddelay:
★Wax soo saarka dunida ee warshadaynta wax soo saarka SBS waxa uu bilaabmay 1960kii.
★Sannadkii 1963dii, shirkadda American Philips Petroleum Company waxay isticmaashay habka isku xidhka si ay u soo saarto kobolymerka SBS ee tooska ah markii ugu horeysay, magaca ganacsiga ee Solprene.
★Sannadkii 1965-kii, Shirkadda Shell ee Maraykanku waxay adeegsatay tignoolajiyada polymerization-ka taban iyo hab quudin saddex-tallaabo ah si ay u horumariso badeecad la mid ah oo ay ku gaadho wax-soo-saar warshadeed, oo leh magaca ganacsiga Kraton D.
★Sannadkii 1967-dii, shirkadda Nederlandka ah ee Philips ayaa soo saartay xiddig (ama radial) alaab SBS ah.
1973dii, Philips waxa uu soo saaray sheyga SBS ee xidigta.
★Sannadkii 1980kii, Shirkadda Firestone waxay soo saartay badeecad SBS ah oo lagu magacaabo Streon. Waxyaabaha ku xidha styrene ee alaabtu waxay ahayd 43%. Alaabtu waxay lahayd tusm dhalaal sare leh waxaana inta badan loo isticmaali jiray wax ka beddelka caagagga iyo xabagta dhalaalka kulul. Ka dib, Shirkadda Japan ee Asahi Kasei, Shirkadda Anic ee Talyaaniga, Shirkadda Petrochim ee Belgium, iwm. ayaa sidoo kale si isdaba-joog ah u horumarisay alaabada SBS.
★Ka dib markii la soo galay 1990-meeyadii, iyada oo si isdaba joog ah loo ballaariyay goobaha codsiyada SBS, wax soo saarka SBS ee adduunka ayaa si degdeg ah u horumaray.
★Tan iyo 1990-kii, markii warshadda cinjirka synthetic ee Shirkadda Baling Petrochemical ee Yueyang, Gobolka Hunan waxay dhistay qalabkii ugu horreeyay ee SBS ee dalka oo soo saara 10,000 oo tan sanadkiiba iyadoo la adeegsanayo tignoolajiyada Machadka Cilmi-baarista ee Beijing Yanshan Petrochemical, awoodda wax-soo-saarka Shiinaha ee SBS ayaa si joogto ah u kortay. .
