Kule veki iphelileyo, imakethi yemveliso yekhemikhali yasekhaya iqhubeka inamava ngendlela esezantsi, kunye nokwehla ngokupheleleyo ukwanda kuthelekiswa neveki ephelileyo. Uhlalutyo lwentengiso yemakethi yee-Indies ezisezantsi
I-1. Metanol
Kule veki iphelileyo, intengiso yeMethanol yakhawulezisa indlela yayo ezantsi. Ukususela kwiveki ephelileyo, imakethi yamalahle iqhubekile nokuwela, inkxaso yeendleko iwile, kwaye imakethi yeMethanol iphantsi koxinzelelo kwaye ukuhla kwezensi kuye kwanda. Ngapha koko, ukuqala kwakhona kwezixhobo zolondolozo kwangoko kukhokelele ekunyukeni, okhokelela kwintengiso eyomeleleyo yentengiso kunye nokwandisa imakethi yemarike. Nangona kukho imfuno eqinileyo yokugcwaliswa kwimarike emva kweentsuku ezininzi zokuhla, imfuno yemakethi ihlala ibuthathaka, ngakumbi njengoko iimakethi zemasethi ezihamba ngexesha lentengiso yeMethanol.
Ngemini ye-26 kaMeyi, i-Indet yeThengiso yeMakethi yeMethanol eMzantsi China yayivaliwe kwi-933.66, ezantsi i-7.61% ukusuka ngolwesihlanu odlulileyo (Meyi 19).
I-2. Isoda yeCaustic
Kule veki iphelileyo, imakethi ye-alkali i-alkali yokuqala yawa emva koko yawa. Ekuqaleni kweveki, kukhangelwa lulondolozo lwezityalo ze-chlor alkali emantla naseMpuma China, imfuno yesitokhwe ekupheleni kwe-chlorine yolwelo, intengiso yemakethi iphuculwe, kunye nentengiso yentengiso ye i-alkali iphinde yahlaziywa; Nangona kunjalo, amaxesha amnandi akazange agqibe ixesha elide, kwaye kwakungekho kuphuculo olukhulu kakhulu kwimfuno ye-downwin. Imbonakalo yentengiso iyonke yayilinganiselwe kwaye intengiso inqabile.
Kule veki iphelileyo, imakethi ye-Alkali ye-Alkali yayikukunyuka kwayo. Ngenxa yokwehla kwexabiso lentengiso ekuqaleni kwenqanaba lokuqala, intengo esezantsi eqhubekayo ivuselela imfuno yabadlali be-Dowream yokugcwaliswa kwakhona, kwaye ukuthunyelwa komenzi kuphuculwe, oko kuphuculwe i-Sland yeSoda yeFlaustic Soda. Nangona kunjalo, ngokunyuka kwamaxabiso entengiso, ibango lentengiso liphinde lacinezelwa, kwaye imakethi yentloko ephambili iyaqhubeka ukutyhala ngokubuthathaka.
Ngomhla wamashumi amabini anesithandathu
Amanqaku ayi-02, ezantsi i-0.09% ukusuka ngolwesihlanu odlulileyo (nge-19).
I-3. I-Ethylene Glycol
Kule veki iphelileyo, ukwehla kwentengiso ye-galylene ye-galylene ye-glycol ekhawulezileyo. Ngokwanda kwinqanaba lokusebenza kwentengiso ye-Ethylene Glycol kunye nokunyuka kwe-Porvery Uluhlu lweempahla, ukubonelelwa ngokubanzi kuye kwandiswa kakhulu, kwaye isimo sengqondo sentengiso siye sakhula. Ngapha koko, ukusebenza kwe-sliggish yentengiso yentengiso kwiveki ephelileyo kukhokelele ukwanda kwesantya sokwehla kwimarike ye-Ethylene Glycol.
Nge-26 kaMeyi 26, i-Ethylene Glycoco Ply Index kwi-South China ivaliwe kumanqaku angama-685.71, ukwehla kwe-3.45% kuthelekiswa nolwesihlanu odlulileyo (nge-19).
I-4. Isyrene
Kule veki iphelileyo, imakethi ye-styrene yasekhaya iqhubeka ukwehla. Ekuqaleni kweveki, nangona ioli evuthiweyo yaphinda yahlaziywa, kwabakho imvakalelo eqinileyo ye-pessimism yeyona ntengiso, kwaye imakethi ye-styrene yaqhubeka ukwehla phantsi koxinzelelo. Ingakumbi, imakethi inengqondo eyomeleleyo ye-bale kwimakethi yekhemikhali yasekhaya, ekhuphile ukwanda koxinzelelo kwintengiso ye-styrene, kwaye imakethi ephambili iqhubela phambili.
Nge-26 kaMeyi 26, Isalathiso samaxabiso e-sty

Uhlalutyo lweMatriki
Nangona i-Inventi ye-US iphosa kabukhali kule veki, ngenxa yemfuno eqinileyo e-US ehlotyeni, kwaye unciphiso lwemveliso + lwemveliso lwazisa iingenelo, i-US Grisis ye-US ayisonjululwa. Ukongeza, ukulindelwa kwezakhiwo ze-European noMelican Ressal Recessions, nto leyo enokuthi ichaphazele kakhulu imeko yeoyile yeoyile yamanye amazwe. Kulindelwe ukuba isayekele ingcinezelo yasezantsi kwimakethi yeoyile yamanye amazwe. Ukusuka kwimbono yasekhaya, imakethi yeoyile yamanye amazwe ifumana ukungasebenzi kakuhle, inkxaso yeendleko ezilinganiselweyo, kunye nemarike yemichiza yasekhaya ingahlala ibuthathaka kwaye iguquke. Ngapha koko, ezinye zeemveliso zekhemikhali ezinamakhamamikhali zingenile kwixesha le-off yemfuno yehlobo, kwaye imfuno yeemveliso zeekhemikhali zisabuthathaka. Ke ngoko, kulindeleke ukuba indawo yokuqala kwimakethi yekhemikhali ilinganiselwe.
I-1. Metanol
Kutshanje, abavelisi abanjengeXinjiang Xinye banolondolozo lwe-China, kodwa i-Shaanandi kwi-China yeShedyshore Sportshore yeShedyshore, i-Shaankethi, kunye ne-Inner Mongolia, engahambelani nemakethi yeMethanol . Ngokwemfuno, inzondelelo yeeyunithi eziphambili zeOlefin ukuqala ukwakhiwa akuphakami kwaye kuhlala kuzinzile. Ukongeza, imfuno ye-MTBE, i-formaldehyde, kunye nezinye iimveliso zikhule kancinane, kodwa ukuphuculwa kwemfuno kuphelile. Lilonke, kulindeleke ukuba imakethi yeMethanol izakuhlala ibuthathaka kwaye iguqukele ngaphandle kokuthengiswa okwaneleyo kunye nemfuno enzima yokulandela.
I-2. Isoda yeCaustic
Ngokuphathelele i-alkali i-alkali, kukho umzuzu ophezulu kwimarike ye-alkali yasekhaya. Ngenxa yempembelelo entle yolondolozo ngabanye abavelisi kwingingqi yeJiangsu, imakethi ye-alkali i-Alkali ibonakalise i-edomnum ephezulu. Nangona kunjalo, abadlali abaphantsi abaphantsi banomdla olinganiselweyo wokufumana iimpahla, ezinokusenza buthathaka inkxaso yazo kwintengiso ye-alkali ye-alkali kwaye inciphise ukunyuka kwamaxabiso entengiso ephambili.
Ngokuphathelele kwi-Flake Alkali, i-Alkeli Alkali Alkali inomda omncinci. Abanye abavelisi basabonisa iimpawu zokutyhala amaxabiso abo okuhambisa, kodwa eyona meko yentengiselwano inokuxinwa yindawo yentengiso yentengiso ephambili. Ke ngoko, zithini izithintelo kwimeko yentengiso.
I-3. I-Ethylene Glycol
Kulindelwe ukuba ubuthathaka bentengiso ye-Ethylene Glycol iya kuqhubeka. Ukunyuka kwentengiso yeoyile yamanye amazwe i-SHEOD ilinganiselwe, kwaye inkxaso yeendleko ilinganiselwe. Kwicala lokuhambisa, ngokutshintsha izixhobo zokuqala zolondolozo, zilindelwe kukwanda koncedo lweentengiso, ezikwimeko yentengiso ye-Ethylene Glycol. Ngokwemfuno, imveliso ye-pontuster iyaphucuka, kodwa isantya sokukhula siyacotha kwaye intengiso iphela ingenayomntum.
I-4. Isyrene
Indawo elindelweyo ephezulu yentengiso ye-styrene ilinganiselwe. Imo ye-oyile ye-oyile yamanye amazwe ibuthathaka, ngelixa ukuthengisa i-Bezene Nemenzi ye-Bezene kunye neStyrene ibuthathaka, ixhasa inkxaso ebuthathaka yeendleko. Nangona kunjalo, kukho utshintsho oluncinci kunikezelo olupheleleyo kunye nemfuno, kwaye imakethi ye-styrene inokuqhubeka nokufumana utshintsho oluncinci.
