Ka dib markii benzene saafi ah / hydrobenzene ay hoos ugu dhacday 6000 yuan calaamad, oo ay ku riixday fududeynta wanaagsan ee siyaasadda qaranka, dareenka suuqgeynta ee suuqa ayaa isbeddelay wax yar, ganacsatada qaar iyo iibsashada gorgortanka hoose, mugga macaamilka benzene / hydrobenzene saafi ah, ayaa kor u qaaday qiimaha kor u kaca, sida of Juun 16, Qiimaha benzene saliidda ee Shandong wuxuu ahaa qiyaastii 6220 yuan/ton, koror ah 80-140 yuan/ton. Aasaaska dib u soo celinta hydrobenzene ee usbuucan.

Waqtigan xaadirka ah, diiradda suuqa ayaa ah kororka heerka isticmaalka ee awoodda styrene, hoos u dhaca heerka hawlgalka ee phenol iyo kororka soo dejinta benzene saafi ah.

1, isticmaalka awoodda styrene-ka hoose ee hoose ayaa la filayaa inuu kordho

Qeybta hore ee warshadda styrene ee la joojiyay ayaa qorsheyneysa inay dib u bilowdo, oo ay weheliso Zhejiang Petrochemical 600,000 oo tan oo qalab ah ayaa la dhigay 15 saac ee Juun 16, laga soo bilaabo wax soo saarka styrene ee Shiinaha iyo xogta isticmaalka awoodda ayaa la filayaa inay hagaajiso guud ahaan. Isticmaalka awoodda Styrene waxay kordhin doontaa baahida loo qabo benzene saafi ah, waxay kordhin doontaa isticmaalka benzene saafi ah, laakiin ka dib korodhka heerka hawlgalka styrene, weli waa lagama maarmaan in fiiro gaar ah loo yeesho isbarbardhigga hoose ee styrene, haddii qulqulka hoose ee styrene ay adagtahay Si loo gaaro horumar isku mid ah, styrene waxay wajaheysaa xaaladda saadka iyo dhimista baahida, ka dib oo dhan, styrene waxay si tartiib tartiib ah u geli doontaa heerkulka sare ee xilliga ka baxsan.

2, heerka hoose ee phenol ketone hawlgalka ayaa sii socda inuu hoos u dhaco

Dhawaan ganacsiyada ketone ee phenol-ka hoose waxay bilaabeen heerka 69%, bishii-bishii -1%. Waxaa ka mid ah, inta lagu guda jiro xiritaanka iyo muddada dayactirka ee Jiangsu Ruiheng, Shanghai Sisar iyo Gaoqiao Petrochemical phenol ketone unugyada, Shenghong sifaynta phenol ketone unugyada lahaa hawlgal taban, sidaas darteed heerka hawlgalka phenol ketone ayaa sii waday inuu hoos u dhaco, yaraynta isticmaalka benzene saafi ah, iyo samaynta jawaab celin taban oo ku saabsan benzene/hydrobenzene saafi ah.

3, Soo dejinta benzene saafiga ah ee Shiinaha ayaa la filayaa inay kordhiso

Iyada oo dhamaadka muddada fiirsashada ee dayactirka dibadda, iyo macquulka qiimaha octane ayaa hoos u dhacay, benzene saafi ah ee Asia waxay u baahan tahay inay gasho Shiinaha dheefshiidka, waxaana la filayaa in soo dejinta benzene saafiga ah ee gudaha ay kordho, taasoo horseedaysa kor u kaca benzene saafi ah oo gudaha ah. sahayda, marka laga eego aragtida soo dejinta bishii, soo dejinta ama laga bilaabo 200,000 tan ilaa 300,000 oo tan oo miisaan ah.

Intaa waxaa dheer, Hainan Sifeynta iyo Kiimikada cusub 2.6 milyan oo tan oo quudin dib u habeyn ah, CNOOC Huizhou cusub 1.3 milyan oo tan oo wax soo saarka udugga iyo kala qaybsanaan la filayo in la geliyo feed ka dib, sahayda gudaha ee benzene saafi ah ayaa kordhay.

Muddada gaaban, oo ku lug leh buuxinta hal madhan dhamaadka bisha, waxa la filayaa in jawiga wax iibsiga ee benzene/hydrobenzene saafi ah la wanaajin karo, qiimaha hydrobenzene-na wuu dejin karaa oo dib u soo celin karaa, laakiin dhererka dib u soo celinta iyo xoogga ayaa ah xaddidan, sababtoo ah suuqa ayaa weli ku jira dusha wararka xun, iyo khadka dhexe iyo kan dheer waxaa lagu daaweeyaa fikrado madhan.
