iindaba

Ukususela ekungeneni phakathi nasekupheleni kukaMeyi, i-bearish toluene diisocyanate (TDI) imakethe iye yalawula, ixabiso liye laqhubeka lihla, kwaye ixabiso eliphantsi liye laphula i-yuan ye-17,000 (ixabiso letoni, elifanayo elingezantsi).Ngomhla we-2 Juni, ixabiso lokubhekisela kwe-TDI laliyi-16,000 yuan, phantsi kwe-17.95% xa kuthelekiswa noMeyi 1. Ngexesha elingekhoyo, ukuchasana phakathi kokubonelela kunye nemfuno kunzima ukulungiswa ngexesha elifutshane, kwaye i-market ye-TDI isenayo indawo. uhlengahlengiso olusezantsi.

Ububi buyoyisa

Kutshanje, isixhobo seFujian Wanhua TDI sivelise iimveliso ezifanelekileyo, isixhobo seGansu Yinguang TDI siphinde saqala ngokutyibilikayo.UMeng Xianxing uthe, “Nangona ezi zixhobo zibini ziqhuba ngempumelelo, kodwa ngenxa yokuba imveliso ikwimarike inesiphene, ngoko ke unikezelo lwemarike ye-TDI kunye necala lemfuno alitshintshanga kakhulu, isizathu sokuchaphazela intengiso lutshintsho lwengqondo ngakumbi. ukulindela ukwanda kobonelelo. ”Imibuzo yehle yaba ngumkhenkce, iintengiselwano zihlala zibhityile, neeodolo ezifunekayo zilibazisekile, kwaye amaxabiso e-TDI ehle phantse nge-10% ngeveki.

Ngexesha elifanayo, imarike yangaphandle ye-TDI ayizange ikuphephe ukuhla.Imarike ye-TDI yaseYurophu ikwibhalansi ebuthathaka phakathi konikezelo kunye nemfuno.Nangona iJamani iBASF 300,000 yeetoni/ngonyaka yokupaka indawo yokupaka inkxaso encomekayo, kodwa kwimeko yokudodobala koqoqosho eYurophu nase-United States, ukusebenza kwesiphelo kuseyi-avareji.I-Asia-mpuma ye-Asia TDI ukwehla kwemarike kubonakala ngakumbi, ukusebenza ngokubanzi kwemfuno yengingqi jikelele, ubukhulu becala kufuneka nje ukuthenga, i-superposition ye-market TDI isikhokelo amaxabiso athotyiweyo, abathengi basekhaya ukunqanda ingozi yokuthengwa kwempahla, balindele ukuwa emoyeni.

Abangaphakathi kwishishini babonisa ukuba imarike isalindele ukubona xa i-Gansu Yinguang kunye ne-Fujian Wanhua imveliso ye-TDI ingena kwiimarike kunye nemeko ethile yokusabalalisa.Kwimarike yexesha elizayo, icala lokubonelela lidibeneyo, kodwa isimo sengqondo soshishino sibuthathaka phantsi kwemeko yokuphelelwa ithemba, kwaye iimveliso zezixhobo zeFujian Wanhua zangoku zibekwe kakuhle, kulindeleke ukuba imarike ye-TDI iya kuqhubeka iwa ngexesha elifutshane. ixesha.

Imida yengeniso inciphile

I-Toluene njengeyona nto iphambili ekrwada ye-TDI, imakethi yayo ihlala imile.U-Wang Quanping uthe: "I-petrochemical yaseLuoyang, i-Yatong ye-petrochemical toluene yezixhobo zokucima ukulungiswa, ukubonelela kwalapha kuqinile, amaxabiso okuthunyelwa kwempahla yokucoca athatha ithuba lokunyuka."

Kodwa imfuno yetoluene isebuthathaka.Amaxabiso epetroli asephantsi, imarike yeoli ilinganiselwe kwinzala ye-toluene, imveliso yemveliso yasekhaya ye-ethylbenzene inyukile, amanye amashishini anenkxalabo nge-ethylbenzene kwimarike yeoli ukuze athathe indawo yokusetyenziswa kwe-toluene.

Kwimarike yexesha elizayo, ixabiso le-toluene yasekhaya liye landa kancane, kwelinye icala, ngenxa yokunyuka kwezixhobo zokugcina ekhaya, kwaye ukunikezelwa kwancitshiswa kancane;Ngakolunye uhlangothi, kwimeko yokungabikho kwenzuzo ekuxubeni kwepetroli, ixabiso le-toluene liphantsi kunezinye i-aromatics, kwaye ukuthambekela kokusebenzisa i-toluene ekuxubeni kunamandla, okuya kubangela ukunciphisa ukuthengiswa kwamanye amazwe. yamashishini okucoca asekhaya, kunye neendleko eziphezulu zokubamba izibuko nazo zixhasa ixabiso elinyukayo.Nangona kunjalo, ingeniso ebanzi yommandla osezantsi weshishini lemichiza ihlwempuzekile, kwaye amashishini akanamdla wokuthengwa kwezinto ezikrwada, nto leyo ethintela kakhulu ixabiso letoluene.

Ukusuka kwimbono yeklorini yolwelo, enye imathiriyeli ekrwada ye-TDI, ngenxa yokuba iiyunithi ze-chlor-alkali zomntu kuMntla we-China zingene kwimo yogcino, kukho inkxaso ethile elungileyo evela kwicala lonikezelo, kodwa kuthathelwa ingqalelo ukuba inzuzo yoshishino olusezantsi aluphucukanga. , ixabiso leklorini lexesha elifutshane alizange liguquguquke kakhulu.

Lilonke, ngenxa yexabiso lemarike elomeleleyo lemathiriyeli ekrwada ye-TDI, imida yenzuzo ye-TDI iyaqhubeka nokucutheka.

Imfuno ayikaqalwa

Amaxabiso epolyether athambileyo e-TDI asezantsi aye ehla ngokuthe ngcembe.Nangona icala lonikezelo lokunyuswa lingekho kakhulu, kodwa ukungenisa kwe-TDI kulindeleke ukuba kucinezele ingqondo ye-bullish yemarike, idityaniswa ne-TDI enyukayo kwiziko lemathiriyeli ekrwada yehle, akukho mthamo.

Kwimarike yexesha elizayo, inkxaso esisiseko ye-TDI ayinamandla, kuba ixabiso le-polyether off-season esezantsi liyaqhubeka nokuwa, ukuzimisela kwamashishini e-polyether ukuvula izikhundla akunamandla, kwaye phantsi kweempembelelo ze-polyether inzuzo encinci kunye nexabiso lokubuyela umva. , uxinzelelo lweendleko ze-hydrogen peroxide indlela yepropylene oxide kunye nepropylene oxide / i-styrene inkqubo iyanda, ithuba lokucwangcisa ukulungiswa kweefektri ezinkulu ze-polyether, kwaye imfuno ye-TDI ibuthathaka.

Ukongeza, amathemba angaqinisekanga okubuyiselwa koqoqosho lwehlabathi kulindeleke ukuba aqhubeke nokuchaphazela ukusebenza kwekhonkco leshishini le-TDI.
