Sahayda guud ee glacialacetic acidsuuqa bisha Agoosto wuu sarreeyaa, qaar ka mid ah kuwa hoose ayaa ku jira xilli-xilliyeedka, sidaas darteed baahida loo qabo acetic acid ayaa laga yaabaa inay xaddidan tahay.Maaddaama ay yaraadeen shirkadaha dib-u-habaynta bishan, Shanghai Huayi iyo Dalian Hengli oo keliya ayaa leh qorshayaal dib-u-habayn ah, sahaydu weli way sarraysaa, agabka warshaduhuna waxa uu joogaa heer dhexdhexaad ah.Way adag tahay in la taageero kororka qiimaha sababtoo ah waxaa jira dhinacyo badan oo taban oo ku jira suuqa glacial acetic acid muddada-gaaban.

Sanadihii la soo dhaafay, awoodda wax soo saarka ee glacial acetic acid iyo warshadaheeda hoose ee hoose ayaa muujiyay isbeddel sii kordhaya.Si kastaba ha noqotee, gudbinta faa'iidada ee silsiladda warshadaha maaha mid isku dheelitiran.Mustaqbalka, waxay ahaan doontaa mid ka mid ah darawallada faa'iidada iyo ballaarinta dalabka.Awoodda sahayda ee glacial acetic acid waxay ku xidhan tahay inay kor u kacdo xitaa in ka badan.Waqtigaas, dheelitirka u dhexeeya sahayda iyo baahida waa la jebin doonaa.

Inkasta oo awoodda wax-soo-saarka glacial acetic acid ay si tartiib tartiib ah u kordheyso, isticmaalka ayaa sidoo kale muujinaya isbeddel korriin, laakiin gudbinta faa'iidada ee silsiladda warshaduhu maaha mid dheellitiran, iyo xaaladda faa'iidada ee qaar ka mid ah kuwa hoose ayaa si dhib leh loo odhan karaa waa mid ku habboon.

Awoodda wax-soo-saarka glacial acetic acid ayaa si tartiib tartiib ah u sii fidaysa

Intii lagu jiray 2018-2022, awoodda wax-soo-saarka glacial acetic acid ee Shiinaha ayaa si joogto ah u kordhay, oo ay taageerayaan horumarinta baahida hoose iyo faa'iidada wanaagsan.Laga bilaabo 2022, awoodda wax ku oolka sanadlaha ah ee glacial acetic acid waa 10.46 milyan tan, ilaa 18 t.86% laga bilaabo 2018.

Shantii sano ee la soo dhaafay, qiimaha guud ee glacial acetic acid wuxuu ku socday kor u kac, oo ay taageerto kordhinta baahida gudaha iyo suuqa dhoofinta firfircoon.Isla mar ahaantaana, waxay ilaalisay kala duwanaansho qiimo badan oo leh methanol alaabta ceeriin inta badan, taasoo keentay faa'iido xoog leh iyo waqti dheer oo faa'iido leh.

2017-2018, geedka glacial glacial acetic acid bilaabmaa ahaa mid aan degganayn, iyo suuqa dhoofinta taageero suuqa gudaha.Intaa waxaa dheer, hoos u dhaca awoodda glacial glacial acetic acid iyo ballaarinta awoodda hoose, baahida loo qabo glacial acetic acid ayaa hadda kor u kacday, taas oo si wadajir ah u taageertay kor u kaca qiimaha glacial acetic acid.Inkasta oo isbeddelku asal ahaan la mid yahay kan methanol alaabta ceeriin, kala duwanaanshaha qiimaha ayaa sii kordhaya oo faa'iidada faa'iidada ayaa sii kordhaysa.2018, celceliska faa'iidada guud ee aragtida guud ee suuqa bariga Shiinaha waxay ahayd qiyaastii 1,753 yuan/ton.2019-2020, awoodda wax-soo-saarka glacial glacial acetic acid si joogto ah ayay u kacaysaa oo sahaydu way korodhaa.Baahida ayaa hoos u dhacaysa wejiyada sababo lama filaan ah awgeed.Qiimaha glacial glacial acetic acid waa mid kacsan, iyo farqiga qiimaha methanol ayaa hoos u dhacaya ilaa xad.sanadka 2020, celceliska faa'iidada guud ee aragtida ee suuqa bariga Shiinaha waa ilaa 504 yuan/ton.2021, in kasta oo qiimaha methanol iyo glacial acetic acid labaduba ay kor u kacayaan, qiimaha glacial acetic acid ayaa kor u kacaya sababtoo ah kororka baahida gudaha iyo dibedda iyo hoos u dhaca saadka, taasoo ka dhigaysa farqiga qiimaha u dhexeeya labadoodaba inay sii wadaan balaarinCelceliska wadarta guud ee sanadlaha ee suuqa Bariga Shiinaha wuxuu ahaa ku dhawaad ​​RMB399/ton.41%.

Inkasta oo faa'iidada laga helay ay ahayd mid la taaban karo, baahida hoose waxay muujisay koritaanka joogtada ah, taasoo keentay soosaarayaasha hadda jira iyo ciyaartoyda suuqa cusub si ay u horumariyaan qorshayaasha mashruuca acetic acid cusub, kuwaas oo intooda badan sidoo kale la fuliyay.

Dalabka hoose ee mustaqbalka ayaa weli sii kordhaya

Waxaa weli jira qorshayaal awood cusub oo loogu talagalay badeecooyinka hoose ee mustaqbalka, taasoo horseedaysa koritaanka joogtada ah ee awoodda sahayda acetic acid glacial.

Laga soo bilaabo 2021 ilaa 2022, awoodda wax soo saarka EVA si dhakhso ah ayay u sii fidaysaa alaabadu waxay sidoo kale ku soo dhowaanaysaa kobaca sare ee VA vinyl acetate content, iyada oo ay si weyn u korodhay baahida loo qabo vinyl acetate, ballaarinta awoodda wax soo saarka vinyl acetate, iyo yaraanta sahayda karbide ee aan caan ahayn.Laga soo bilaabo 2022, qaar ka mid ah sahayda kaarbiid-ka kaalshiyamka ayaa lagu kabay isticmaaleyaasha sahayda ethylene asalka ah, qaabka sahayda ethylene acetate ee Shiinaha ayaa ka beddeshay dheeri qaabdhismeed ilaa xiisad dhisme.EVA waxay qayb ahaan tixgelinaysaa ethylene acetate oo iskeed u dhisatay iyadoo ay ugu wacan tahay dhibaatada korodhay iyo qiimaha iibka isticmaaleyaasha.Ilaa wakhtigaas, tiro mashruucyo ah oo la dhisayo ayaa socda oo awoodda wax-soo-saarka ethylene vinyl acetate ayaa la sii deyn doonaa 2023.

Ethyl acetate sidoo kale waa mid ka mid ah wax soo saarka hoose ee glacial acetic acid.Sanadihii la soo dhaafay, iska horimaadka u dhexeeya sahayda iyo baahida ethyl acetate ayaa ahaa mid caan ah, iyo heerka kobaca awoodda ayaa ah mid gaabis ah.2022-2023, awoodda cusub ayaa weli inta badan laga helaa shirkadaha jira, inta badan si ay u ballaariyaan saamiga warshadaha, sii dhimista kharashyada iyo hagaajinta hufnaan.Intaa waxaa dheer, iyadoo isbeddelka hadda jira ee isdhexgalka warshadaha petrochemical uu noqdo mid aad u muuqda, shirkadaha qaar ayaa qorsheynaya inay dhisaan dhirta ethyl acetate cusub si ay u ballaariyaan silsiladda warshadaha.Si kastaba ha ahaatee, sababtoo ah habka wax-soo-saarka fudud ee ethyl acetate, isbeddel degdeg ah ee qalabka gudaha iyo wax-soo-saarka dabacsan, oo inta badan ku salaysan qiimaha iyo isbeddelka baahida, heerka kobaca wax-soo-saarka ayaa hoos u dhacay sannadihii la soo dhaafay.

Marka la eego anhydride acetic, sannadihii ugu dambeeyay, qalab cusub iyo qalab duugoobay ayaa wada jira, iyo sahayda guud waxay muujinaysaa isbeddelka koritaanka.Marka loo eego qaab dhismeedka isticmaalka, waxaa inta badan loo isticmaalaa soo saarista fiber acetate, dhexdhexaadiyeyaasha dawooyinka, dhexdhexaadiyeyaasha cayayaanka, dhir udgoonka, midabada, cuntada lagu daro, wakiilada fuuqbaxa kiimikada iyo beeraha kale.Qaar ka mid ah dhirta fiber acetic-ka gudaha waxaa lagu qalabeeyaa dhirta acetic anhydride, iyo isdhexgalka dhinacyada kale maaha mid sarreeya.Mustaqbalka, dhirta acetic anhydride weli waxay ahaan doontaa dhismo.Ningxia Donghe ayaa qorshaynaysa in ay 150,000 oo tan ku hawl gasho qaybta danbe ee sanadkan.Henan Ruibai ayaa sidoo kale qorsheyneysa inay dhisto warshad cusub oo anhydride ah, waxaana la filayaa in awoodda wax soo saarka warshadaha ay sii wado ballaarinta.Acetic anhydride waxay leedahay meelo kala duwan oo ka mid ah meelaha hoose, waxaana weli jira meelo loogu talagalay koritaanka dhinaca baahida, laakiin kororka awoodda wax-soo-saarka, warshaduhu waxay noqon doonaan kuwo tartan sii kordhaya.

Mashaariic badan oo cusub oo loogu talagalay glacial acetic acid mustaqbalka, dheelitirka sahayda iyo baahida ayaa laga yaabaa in la jebiyo
Waxqabadka faa'iidada wanaagsan ee sanadihii la soo dhaafay, iyo sidoo kale kororka joogtada ah ee baahida hoose, ayaa sahayda glacial acetic acid ayaa sidoo kale sii kordhinaysa dardargelinta, saddexda sano ee soo socotana kama reebna.

Jadwalka kore wuxuu muujinayaa qaar ka mid ah qorshayaasha awoodda cusub ee glacial acetic acid saddexda sano ee soo socota, marka lagu daro shirkadaha qaar ayaa sidoo kale leh qorshooyin dhismo iyo ballaarin cusub, waxaa la arki karaa in kobaca mustaqbalka ee glacial acetic acid weli la filayo in uu noqdo mid yar. weyn.In kasta oo baahida hoose ay sidoo kale yeelan doonto kor u kac joogto ah, laakiin haddii ay si buuxda u nuugi karto sahayda acetic acid ee korodhay ayaa weli ah mid la sii arki doono, lamana saari karo in glacial acetic acid ee Shiinaha uu yeelan doono awood xad dhaaf ah.
