Imakethi ye-cyclohexanone ibonakalise ubuthathaka obuthile kutshanje, amaxabiso esebenza kumanqanaba aphantsi kwaye ishishini lijongene noxinzelelo oluthile lwenzuzo.
I. Amaxabiso eMarike angoku (ekuqaleni kukaSeptemba 2025)
Idatha evela kumaqonga amaninzi olwazi ibonisa ukuba amaxabiso e-cyclohexanone akutshanje ebezinzile ngokubanzi kodwa ebuthathaka. Ukusukela nge-29 ka-Agasti 2025, amaxabiso eMpuma China ehle nge-26.13% unyaka nonyaka, ehlala kwisiphelo esisezantsi soluhlu olubonwe kwiminyaka yakutshanje.
II. Uhlalutyo lweMarike kunye neMbono yeXesha elizayo
Imakethi ye-cyclohexanone iqhubekile nokujongana noxinzelelo kutshanje, ikakhulu ngenxa yezi zizathu zilandelayo:
1.Inkxaso yeendleko enganelanga:
Ixabiso le-benzene ecocekileyo, eyona nto iphambili kwi-cyclohexanone, belisoloko litshintshatshintsha kancinci.
I-benzene ecocekileyo ibangela ngaphezulu kwe-70% yeendleko zokuvelisa i-cyclohexanone. Ixabiso layo eliphantsi linciphisa ngokuthe ngqo ixabiso elisisiseko le-cyclohexanone, nto leyo ebangela ukungabikho kwenkxaso enamandla kwicala leendleko.
2.Ukusebenza kweMfuno ebuthathaka:
Imfuno ephantsi ye-cyclohexanone (umz., i-caprolactam, izinyibilikisi) ichaphazeleke kakubi yimeko-bume yezoqoqosho kunye nokusetyenziswa okubuthathaka kwesiphelo.
Ii-odolo zefayibha yeekhemikhali ezisezantsi ziye zalumka, ukuthengwa kwazo kuqhutywa kakhulu yimfuno enzima, kwaye ukuthengwa kwezinto ezinkulu kwindawo enye kunqabile.
3.Ukwanda kwelahleko kushishino:
Ngenxa yoxinzelelo lweendleko kunye namaxabiso aphantsi emveliso, ilahleko kwishishini le-cyclohexanone ikhule ngakumbi. Idatha ibonisa ukuba ngo-Agasti 2025, amashishini e-cyclohexanone asebenzisa ubuchwepheshe bokumanzisa alahlekelwe yi-RMB 660 ngetoni, nto leyo emele ukunyuka kwenyanga nenyanga.
4.Ubonelelo Oluzinzileyo:
Nangona ezinye izakhiwo zemveliso ziye zatshintsha, ngokubanzi, ukunikezelwa kwe-cyclohexanone kusazinzile. Ukongeza, uthotho lweshishini le-cyclohexanone-caprolactam oludityaniswe kakuhle luye lwachaphazela nomthamo wemveliso yemarike.
Lilonke, kulindeleke ukuba imakethi ye-cyclohexanone iqhubeke nokuqina kwixesha elifutshane. Phantsi koxinzelelo oluphindwe kabini "lwenkxaso yeendleko enganelanga kunye nemfuno ebuthathaka," imakethi isenokugcina umkhwa obuthathaka noguquguqukayo.
III. Izinto ekufuneka zibekwe esweni
Kwixesha elizayo, ezi zinto zilandelayo zinokuchaphazela kakhulu imakethi ye-cyclohexanone:
Iintsingiselo zamaxabiso eoli ekrwada kwihlabathi liphela: Njengomthombo we-benzene ecocekileyo, ukuguquguquka kwamaxabiso eoli ekrwada kuya kudluliselwa kwi-benzene ecocekileyo kunye ne-cyclohexanone.
Ukubuyiselwa kwemfuno esezantsi: Ingakumbi, ukuba imfuno kumashishini afana ne-caprolactam inokuphucula ngempumelelo kuya kuba ngundoqo kwimarike ye-cyclohexanone ephuma kumkhwa wayo obuthathaka.
Imigaqo-nkqubo ye-Macro kunye ne-dynamics yokungenisa/ukuthumela ngaphandle: Imigaqo-nkqubo yerhafu efanelekileyo okanye utshintsho kwimeko-bume yorhwebo lunokuchaphazela iimvakalelo zemarike kunye nemfuno yokwenyani.
IV. Isishwankathelo
Imakethi ye-cyclohexanone yangoku ibonakaliswa kukungalingani okubuthathaka kokunikezelwa kwempahla, inkxaso enganeleyo kwicala leendleko, kunye nokusebenza okungekuhle kwicala lemfuno, okukhokelela ekubeni amaxabiso aqhubeke kumanqanaba aphantsi kwaye ishishini lijongene noxinzelelo lwenzuzo. Kulindeleke ukuba imakethi ihlale ikwimeko yokudibanisa ebuthathaka kwixesha elifutshane.
