Nthawi zambiri, kusintha kwa phula kwa SBS kumafuna njira zitatu: kutupa, kumeta ubweya (kapena kugaya), ndi chitukuko.
Kwa dongosolo la phula losinthidwa la SBS, pali mgwirizano wapamtima pakati pa kutupa ndi kugwirizana. Kukula kwa kutupa kumakhudza mwachindunji kugwirizana. Ngati SBS ifufuma mopanda malire mu phula, dongosololi limagwirizana kwathunthu. Khalidwe lotupa limagwirizana kwambiri ndi kupanga, teknoloji yokonza ndi kusungirako kutentha kwapamwamba kwa phula losinthidwa. Pamene kutentha ukuwonjezeka, mlingo kutupa Imathandizira kwambiri, ndipo kutupa n'zoonekeratu pa Sungunulani processing kutentha kuposa galasi kusintha kutentha kwa PS wa SBS. Kuonjezera apo, mapangidwe a SBS amakhudza kwambiri khalidwe la kutupa: kuthamanga kwa SBS yooneka ngati nyenyezi ndi yocheperapo kusiyana ndi ya SBS yozungulira. Mawerengedwe oyenera amasonyeza kuti kachulukidwe wa zigawo zotupa za SBS zimakhazikika pakati pa 0.97 ndi 1.01g/cm3, yomwe ili pafupi ndi kachulukidwe ka phenol onunkhira.
Kumeta ndi gawo lofunikira pakusintha konse, ndipo zotsatira za kumeta nthawi zambiri zimakhudza zotsatira zomaliza. Mphero ya colloid ndiye pakatikati pa zida zosinthidwa phula. Zimagwira ntchito kumalo otentha kwambiri komanso othamanga kwambiri. Chosanjikiza chakunja cha mphero ya colloid ndi mawonekedwe a jekete okhala ndi makina otsekemera ozungulira. Imagwiranso ntchito yochotsa mantha komanso kuchepetsa phokoso. Mkati mwa mphero ya colloid ndi The annular moving disc ndi annular fixed disc ndi chiwerengero cha malo otsetsereka a mano amagwiritsidwa ntchito popera mipeni. Kusiyana kungasinthidwe. Kufanana kwa kukula kwa tinthu tating'onoting'ono komanso mphamvu ya peptization imatsimikiziridwa ndi kuya ndi m'lifupi mwa mipata ya dzino, kuchuluka kwa mipeni yowotcha, ndi ntchito yeniyeni yopangira mapangidwe. kutsimikiziridwa ndi dera. Pamene mbale yosuntha imayenda mothamanga kwambiri, chosinthiracho chimabalalitsidwa mosalekeza ndi kukameta ubweya wamphamvu ndi kugundana, kugaya particles kukhala tinthu tating'onoting'ono tating'onoting'ono, ndikupanga dongosolo lokhazikika la miscible ndi phula kuti likwaniritse cholinga cha kusakaniza yunifolomu. Pambuyo pakutupa kwathunthu, SBS ndi phula zimasakanizidwa mofanana. Tizigawo tating'onoting'ono tating'onoting'ono, timakulitsa kuchuluka kwa kuchuluka kwa SBS mu phula, komanso momwe phula losinthidwa limathandizira. Nthawi zambiri, kuti mukwaniritse zotsatira zabwino, kugaya kumatha kuchitika kangapo.
Kupanga phula losinthidwa potsirizira pake kumadutsa njira yachitukuko. Pambuyo popera, phula limalowa mu thanki yomalizidwa kapena thanki yachitukuko. Kutentha kumayendetsedwa pa 170-190 ° C, ndipo ndondomeko ya chitukuko ikuchitika kwa nthawi inayake pansi pa chosakaniza. Pochita izi, mtundu wina wa phula lokhazikika losinthidwa nthawi zambiri limawonjezeredwa kuti phula losinthidwa likhale lokhazikika. Mkhalidwe wamakono waukadaulo wopanga phula wa SBS wosinthidwa
. China imapanga pafupifupi matani 8 miliyoni a phula losinthidwa la SBS m'misewu chaka chilichonse, ndipo ukadaulo wapamwamba kwambiri wopangira ndi kugwiritsa ntchito uli ku China. Chenjerani ndi zokopa zabodza ndi zopotoka kuchokera kwa gulu la comprador;
2. Pambuyo pa zaka pafupifupi 60 za chitukuko, luso la phula la SBS losinthidwa lafika padenga panthawiyi. Popanda kusintha kosinthika, sipadzakhala luso lotsalira;
Chachitatu, sichinthu choposa kusintha mobwerezabwereza ndi kusakaniza kwa mayesero a zipangizo zinayi: phula loyambira, SBS modifier, mafuta osakaniza (mafuta onunkhira, mafuta opangira, mafuta a naphthenic, etc.), ndi stabilizer;
3. Kuyendetsa galimoto yapamwamba sikukhudzana ndi luso loyendetsa galimoto. Zigayo zotumizidwa kunja ndi zida zapamwamba siziyimira mulingo waukadaulo wosinthidwa wa phula. Kumlingo waukulu, akungowonetsa ndalama. Pankhani ya zizindikiro zokhazikika, makamaka kuonetsetsa zizindikiro zatsopano zamakono, kupanga zopanda pake monga Rizhao Keshijia kungakhale kotsimikizika;
4. Mabizinesi aboma monga Provincial Communications Investment and Control akonza zopanga ndi kukonza phula losinthidwa la SBS, ndipo akhala a boma. Sikelo ndi yaikulu. Kuphatikiza pa kupikisana kuti apindule ndi anthu, sangathe kuyimira zokolola zapamwamba kapena zatsopano;
5. Pali kufunikira kofulumira kupanga ukadaulo wowunikira pa intaneti ndi zida zopangitsa kuti ntchitoyi ikhale yokhazikika;
6. Mumsika wa Nyanja Yofiira, phindu silingatheke, zomwe zapangitsa kuti "trinitrile amine" isinthe.
