Ngokuvamile, ukuguqulwa kwe-SBS kwetiyela kudinga izinqubo ezintathu: ukuvuvukala, ukugunda (noma ukugaya), nokuthuthukiswa.
Ohlelweni lwebitumen olulungisiwe lwe-SBS, kunobudlelwano obuseduze phakathi kokuvuvukala nokuhambisana. Ubukhulu bokuvuvukala buthinta ngokuqondile ukuhambisana. Uma i-SBS ikhukhumala ngokungenamkhawulo etiyela, uhlelo luhambisana ngokuphelele. Ukuziphatha kokuvuvukala kuhlobene eduze nokukhiqiza, ubuchwepheshe bokucubungula kanye nokuzinza kwesitoreji esiphezulu se-bitumen eguquliwe. Njengoba izinga lokushisa likhuphuka, izinga lokuvuvukala liyashesha kakhulu, futhi ukuvuvukala kubonakala ekushiseni kokuncibilika kokucubungula okuphezulu kunokushisa kwengilazi yokuguqulwa kwe-PS ye-SBS. Ukwengeza, isakhiwo se-SBS sinomthelela omkhulu ekuziphatheni kokuvuvukala: isivinini sokuvuvukala se-SBS esimise okwenkanyezi sihamba kancane kune-SBS yomugqa. Izibalo ezifanele zibonisa ukuthi ukuminyana kwezingxenye zokuvuvukala kwe-SBS kugxiliswe phakathi kuka-0.97 no-1.01g/cm3, okusondelene nokuminyana kwama-phenols anuka kamnandi.
Ukugunda kuyisinyathelo esibalulekile kuyo yonke inqubo yokuguqula, futhi umphumela wokugunda ngokuvamile uthinta umphumela wokugcina. Isigayo se-colloid siwumgogodla wempahla yebitumen eshintshiwe. Isebenza endaweni enezinga eliphezulu lokushisa kanye nesivinini esikhulu. Ungqimba lwangaphandle lwesigayo se-colloid yisakhiwo sejazi elinesistimu yokufakelwa kokujikeleza. Iphinde idlale indima yokumunca ukushaqeka kanye nokunciphisa umsindo. Ingaphakathi le-colloid mill yi-Annular moving disc kanye ne-annular fixed disc enenombolo ethile yezimbobo zamazinyo asetshenziselwa ukugaya imimese. Igebe lingalungiswa. Ukufana kosayizi wezinhlayiya ezibonakalayo kanye nomthelela we-peptization kunqunywa ukujula nobubanzi bezikhala zamazinyo, inani lemimese yokulola, nomsebenzi othize wokwakha isakhiwo. kunqunywa isifunda. Njengoba ipuleti elinyakazayo lizungeza ngesivinini esikhulu, isilungisi sihlakazwa ngokuqhubekayo ukugunda okuqinile nokushayisana, sigaya izinhlayiya zibe yizinhlayiya ezinhle, futhi senza uhlelo oluqinile lokuxutshwa ngetiyela ukuze kufezwe injongo yokuhlanganisa okufanayo. Ngemva kokuvuvukala okugcwele, i-SBS nebitumen kuxutshwa ngokulinganayo. Uma izinhlayiya zokugaya ziba zincane, izinga lokuhlakazeka kwe-SBS ku-bitumen liphezulu, futhi kuba ngcono nokusebenza kwebitumen eguquliwe. Ngokuvamile, ukuze kuzuzwe imiphumela engcono, ukugaya kungenziwa izikhathi eziningi.
Ukukhiqizwa kwetiyela eliguquliwe ekugcineni kuhamba ngenqubo yokuthuthukiswa. Ngemva kokugaya, i-bitumen ingena ethangini lomkhiqizo ophelile noma ithangi lokuthuthukisa. Ukushisa kulawulwa ku-170-190 ° C, futhi inqubo yokuthuthukiswa yenziwa isikhathi esithile ngaphansi kwesenzo somxube. Kule nqubo, uhlobo oluthile lwe-bitumen stabilizer eguquliwe ngokuvamile luyengezwa ukuze kuthuthukiswe ukuzinza kwesitoreji sebitumen eguquliwe. Isimo samanje sobuchwepheshe bokukhiqiza ibitumen obulungisiwe be-SBS
. I-China ikhiqiza cishe amathani ayizigidi ezingu-8 etiyela elishintshiwe le-SBS minyaka yonke, futhi ubuchwepheshe obungcono kakhulu bokukhiqiza nokufakwa kwezicelo kuse-China. Qaphela inkulumo-ze engamanga nehlanekezelwe evela esigabeni se-comprador;
2. Ngemva kweminyaka ecishe ibe ngu-60 yentuthuko, ubuchwepheshe be-bitumen eguquliwe ye-SBS bufinyelele ophahleni kulesi sigaba. Ngaphandle kokuphumelela kwezinguquko, ngeke bube khona ubuchwepheshe obusele;
Okwesithathu, akuyona into engaphezu kokulungiswa okuphindaphindiwe nokuhlanganiswa kwesivivinyo sezinto ezine: i-bitumen eyisisekelo, i-SBS modifier, uwoyela oxubile (amafutha anamakha, amafutha okwenziwa, amafutha e-naphthenic, njll.), kanye ne-stabilizer;
3. Ukushayela imoto kanokusho akuhlangene namakhono okushayela. Izigayo ezivela kwamanye amazwe kanye nezinto zokusebenza ezisezingeni eliphezulu azimeli izinga lobuchwepheshe bebitumen obuguquliwe. Ngokwezinga elikhulu, bamane bebukisa ngemali. Ngokuphathelene nezinkomba ezizinzile, ikakhulukazi ukuqinisekisa izinkomba ezintsha zobuchwepheshe, ukukhiqizwa okungagayeki njenge-Rizhao Keshijia kungaqinisekiswa kakhulu;
4. Amabhizinisi kahulumeni afana Notshalomali Nokulawula Kwezokuxhumana KwesiFundazwe ahlele ukukhiqizwa kanye nokucutshungulwa kwetiyela eliguquliwe le-SBS, futhi ngezikahulumeni. Isikali sikhulu. Ngaphezu kokuncintisana ngenzuzo nabantu, abakwazi ukumela ukukhiqiza okuthuthukile noma okusha;
5. Kunesidingo esiphuthumayo sokuthuthukisa ubuchwepheshe bokuqapha ku-inthanethi namathuluzi okwenza inqubo ilawulwe;
6. Emakethe yoLwandle Olubomvu, inzuzo ayinakusimama, okubangele izinguquko eziningi ze-"trinitrile amine".
