Iimarike yepropylene oxide"I-Jinjiu" yaqhubeka nokunyuka kwayo kwangaphambili, kwaye imarike yaqhekeza i-yuan eyi-10000 (ixabiso letoni, elifanayo elingezantsi) kwinqanaba. Ukuthatha imarike yeShandong njengomzekelo, ixabiso lemarike linyuke laya kwi-10500 ~ 10600 yuan ngoSeptemba 15, malunga ne-1000 yuan ukususela ekupheleni kuka-Agasti. Ngomhla wama-20 kuSeptemba, ibuyele malunga ne-9800 yuan. Kwixesha elizayo, icala lokubonelela lilindeleke ukuba likhule, ixesha lokunyuka kwemfuno alinamandla, kwaye ipropylene oxide iguquguquka kwi-yuan eyi-10000.
Ukonyuka kweyunithi yepropylene oxide ukuqalisa kwakhona unikezelo
Ngo-Agasti, iisethi ze-8 zeeyunithi ze-propylene oxide zagqitywa e-China, ezibandakanya umthamo opheleleyo weetoni ze-1222000 / ngonyaka kunye nokulahlekelwa okupheleleyo kweetoni ze-61500. Ngo-Agasti, imveliso yesityalo sepropylene oxide yasekhaya yayiyi-293200 tons, phantsi kwe-2.17% ngenyanga ngenyanga, kwaye izinga lokusetyenziswa kwamandla laliyi-70.83%.
NgoSeptemba, iyunithi ye-Sinochem Quanzhou propylene oxide yavalwa ukuze igcinwe, i-Tianjin Bohai Chemical, i-Changling, i-Shandong Huatai kunye nezinye iiyunithi zaphinda zaqalwa ngokulandelelana, kwaye iyunithi ye-Jinling yancitshiswa ukuya kwisiqingatha sokusebenza komthwalo. Okwangoku, izinga lokusebenza lepropylene oxide lisondele kwi-70%, lingaphantsi kancinci kunolo ngo-Agasti.
Kwixesha elizayo, iyunithi ye-100000 t/a ye-Shandong Daze iya kuqalisa kwakhona imveliso ekupheleni kukaSeptemba, kwaye i-Jincheng Petrochemical's 300000 t/a unit kulindeleke ukuba ifakwe kwimveliso ekupheleni kukaSeptemba; Izityalo zeJinling kunye neHuatai zibuyela kwinyathelo lokuvelisa ngenyathelo. Icala lokubonelela lilongezelelekileyo, kwaye abarhwebi bane-bearish ngaphezulu. Kulindeleke ukuba i-market propylene oxide ibonise i-trend ebuthathaka yokumisa phantsi kokunyuka koxinzelelo lokubonelela, kunye nomngcipheko omncinci wokuhla.
Inkxaso yepropylene oxide ekrwada kulindeleke ukuba ibe nzima
Kwizinto eziphakamileyo zepropylene kunye neklorine engamanzi, nangona "iJinjiu" ingenise i-wave yemarike ekhulayo, kulindeleke ukuba kube lula ukuwa kunokunyuka kwimarike yexesha elizayo, okuya kuba nzima ukwenza ukutsalwa okuqinileyo. ezantsi.
NgoSeptemba, ixabiso lepropylene, i-propylene ephuma phezulu, yaqhubeka inyuka ngokukrakra, ekwabonelela ngenkxaso eqinile kwimarike yepropylene oxide. Wang Quanping, injineli eyintloko ye-Shandong Kenli Petrochemical Group, uthe unikezelo lwepropylene lwasekhaya luhlala luqinile, kunye nokusebenza okucacileyo kumntla-ntshona, kumbindi nakwimpuma yeChina. Ukongeza, ezinye izixhobo zokulungisa ezisezantsi kwepropylene, ezifana neTianjian Butyl Octanol, Dagu Epoxy Propane, kunye neKroll Acrylonitrile, ziphinde zaqala ukwakha. Ke ngoko, imfuno yentengiso inyuswe phezulu, amashishini epropylene athengisa ngokutyibilikayo, kwaye uluhlu oluphantsi lwempahla luqhube amaxabiso epropylene phezulu.
Ngokombono weyunithi yokusebenza, kwelinye icala, iXintai Petrochemical kunye neeyunithi zepropylene zaphinda zaqalwa, kodwa impembelelo yayilinganiselwe ngenxa yokulibaziseka rhoqo. Kwangaxeshanye, ezinye izakhono ezintsha zokuvelisa ipropane dehydrogenation kwipropylene eShandong zafakwa ekusebenzeni ngaphantsi kunokuba bekulindelwe, kwaye unikezelo lulonke lwalulawuleka. Ngakolunye uhlangothi, kwixesha elizayo elingekude, ezinye iiyunithi ezinkulu kumntla-ntshona zivaliwe ukuze zigcinwe, kwaye ukuqala kwepropylene kumntla-ntshona kwehle ukuya kwi-73.42%. Ukujikeleza kwempahla yepropylene yeperipheral yehle kakhulu. Ukongeza, ezinye izityalo zasemntla-ntshona zigcine imfuno yepropylene yemveliso yangaphandle, kwaye ukunikezelwa kwepropylene ye-peripheral kuye kwaqiniswa kakhulu.
Kwixesha elizayo, umthwalo weyunithi wamashishini epropylene uzinzile, kwaye akukho kulindela utshintsho olubalulekileyo kwipropylene. Imimandla esecaleni yaseShandong kunye neMpuma yeChina isaza kugcina ubonelelo oluqinileyo. Umsinga osezantsi uthande ukuba buthathaka ngepleyiti, ucinezela umdla wokuthenga wepropylene ezantsi. Ngoko ke, i-market propylene yangoku ikwimeko yokubonelela obuthathaka kunye nemfuno, kodwa i-octanol ephantsi, i-propylene oxide, i-acrylonitrile kunye namanye amashishini anyuse umthwalo wabo, kwaye icala eliqinileyo lifuna inkxaso. Kulindeleke ukuba ixabiso elilandelayo lepropylene liguquguquke kuluhlu oluncinci, ngokunyuka okulinganiselwe kunye nokuwa.
Enye imathiriyeli ekrwada, i-chlorine elulwelo, ngumdlali ophambili kwimarike. Umthamo wokuthengisa wangaphandle wokugcinwa kwezixhobo ezithile zeefektri ezinkulu wehla kancinci, kwaye abanye abavelisi kumbindi weShandong bebengazinzanga, nto leyo exhasa imarike ukuba iqhubeke nokunyuka ukuya kuthi ga kwinqanaba elithile. Umzantsi wamandla amakhulu e-East China ubuyile, imfuno iyancipha, kwaye ezinye izixhobo zivaliwe ukuze zigcinwe. Unikezelo lunciphile. Imeko encomekayo kwicala lobonelelo kunye nebango iye yaphakama kwindlela yokunyuka kwimarike yaseShandong, iqhuba ujoliso lwentengiselwano lulonke lwemarike ukunyuka. UMeng Xianxing uthe ngokufunyanwa kwezixhobo zokunciphisa imveliso kunye nokunyuka konikezelo, ixabiso leklorini yolwelo linokwehla kwixesha elizayo.
Imfuno yepropylene oxide iyacotha kwaye kunzima ukuphumelela ngamaxesha onyaka aphezulu
I-polyether polyol yeyona mveliso ibalulekileyo esezantsi kwepropylene oxide kunye neyona nto iphambili yemathiriyeli ekrwada ye-polyurethane synthesis. Umthamo ogqithileyo weshishini lasekhaya le-polyurethane ezantsi, ngakumbi uxinzelelo olugqithileyo kwimarike yogwebu oluthambileyo, lukhulu.
UMeng Xianxing uthe ngoSeptemba, eqhutywa ziindleko, imarike ye-polyether ethambileyo ye-foam yavuka, kwaye imboni ephambili iqhubekile nokuxhasa imarike, kodwa ukusebenza okusezantsi bekuyi-avareji, kunye nokufikelela okuphakathi nasezantsi bekusephantsi.
Okwangoku, isiponji esisezantsi sikhula ngokuthe ngcembe, iindleko ezinyukayo zisafuna ukuhanjiswa ngakumbi, indawo ephakathi nendawo esezantsi igcina ukugaya kunye nokulinda, kwaye imarike eqinileyo iyaqhubeka ilula. Kwixesha elizayo, nangona iindaba ezimbi zokwenyani zingekabikho, abavelisi abaninzi basaswele indawo ngenxa yokunyanzeliswa kweendleko, kwaye indima yabo ekuxhaseni izinto eziluhlaza zilinganiselwe.
Kwelinye icala, imakethi yepolyether yefoam esezantsi igcine ukuthambeka okunyukayo, kwaye indawo ephakathi kunye nesezantsi iqhubekile nokuthenga ngokwemfuno. Nangona umsebenzi uwonke ubungaphantsi kunexesha elifanayo, uye waphucuka xa kuthelekiswa nekota yesibini. Nangona kungena "iJinjiu", akukho tshintsho olucacileyo kwimfuno yemarike, kwaye i-factory inquma imveliso ngokusekelwe kwimfuno.
Kwixesha elizayo, amashishini asezantsi kakhulu alinda kwaye abone, kwaye ukuzimisela kwabo ukuthenga iiodolo ezintsha kubanzi. Kwimeko yokurhweba obuthathaka kunye notyalo-mali, i-polyether ye-foam enzima "iJinjiu" ayilungile ngokwaneleyo ukujoba amandla kwindawo ephezulu.
