Waxaa la arkay in qiimaha badeecadaha kiimikaad ee suuqa ay sii wadaan inay hoos u dhacaan, taasoo horseedaysa dheelitir la'aanta qiimaha ee inta badan isku xirka silsiladda warshadaha kiimikada.Qiimaha saliidda sare ee joogtada ah ayaa kor u qaaday cadaadiska kharashka ee silsiladda warshadaha kiimikada, iyo dhaqaalaha wax soo saarka ee alaabooyin badan oo kiimiko ah ayaa liita.Si kastaba ha ahaatee, qiimaha suuqa ee vinyl acetate ayaa sidoo kale la kulmay hoos u dhac joogto ah, laakiin faa'iidada wax soo saarka ayaa weli ah mid sare iyo dhaqaalaha wax soo saarku waa wanaagsan yahay.Haddaba, maxay noqon kartaavinyl acetatesuuqa ayaa ilaalinaya heerka sare ee barwaaqada?

Laga bilaabo bartamihii ilaa dabayaaqadii Juun 2023, qiimaha suuqa ee vinyl acetate waa 6400 yuan/ton.Marka loo eego heerarka qiimaha alaabta ceeriin ee habka ethylene iyo habka calcium carbide, heerka faa'iidada ee habka ethylene vinyl acetate waa qiyaastii 14%, halka faa'iidada faa'iidada ee habka calcium carbide vinyl acetate uu ku jiro xaalad khasaare ah.In kasta oo uu hoos u dhac joogto ah ku yimid qiimaha vinyl acetate muddo sannad ah, faa'iidada faa'iidada ee ethylene ku salaysan vinyl acetate ayaa weli ah mid aad u sarreeya, oo gaarta ilaa 47% xaaladaha qaarkood, noqoshada faa'iidada ugu sareysa ee faa'iidada ugu sareysa ee kiimikooyinka badan.Taas bedelkeeda, habka karbide calcium ee vinyl acetate wuxuu ku jiray xaalad khasaare ah inta badan labadii sano ee la soo dhaafay.

Marka la falanqeeyo isbeddelada faa'iidada faa'iidada ee ethylene ku salaysan vinyl acetate iyo calcium carbide ku salaysan vinyl acetate, waxaa la ogaaday in ethylene ku salaysan vinyl acetate ay had iyo jeer faa'iido leedahay dhowrkii sano ee la soo dhaafay, iyada oo faa'iidada ugu sareysa ay gaartay 50% ama ka badan iyo celcelis ahaan. heerka dulsaarka faa'iidada qiyaastii 15%.Tani waxay muujinaysaa in vinyl acetate ee ku salaysan ethylene ay faa'iido badan lahayd labadii sano ee la soo dhaafay, oo leh barwaaqo guud oo wanaagsan iyo faa'iido xasilloon.Labadii sano ee la soo dhaafay, marka laga reebo faa'iidada la taaban karo laga bilaabo Maarso 2022 ilaa Luulyo 2022, habka kaalshiyamka carbide ee vinyl acetate wuxuu ku jiray xaalad khasaare ah dhammaan xilliyada kale.Laga bilaabo Juun 2023, heerka faa'iidada ee habka calcium carbide vinyl acetate wuxuu ahaa ku dhawaad ​​20% khasaaro, iyo celceliska faa'iidada ee habka calcium carbide vinyl acetate labadii sano ee la soo dhaafay waxay ahayd 0.2% khasaaro.Laga soo bilaabo tan, waxaa la arki karaa in barwaaqada habka calcium carbide ee loogu talagalay vinyl acetate ay liidato, xaaladda guudna waxay muujinaysaa khasaare.

Falanqaynta dheeraadka ah, sababaha ugu muhiimsan ee faa'iidada sare leh ee wax soo saarka vinyl acetate ee ethylene ku salaysan waa sida soo socota: marka hore, saamiga kharashka alaabta ceeriin ee hababka wax soo saarka kala duwan ayaa kala duwan.Habka ethylene ee vinyl acetate, isticmaalka cutubka ethylene waa 0.35, iyo isticmaalka cutubka acetic acid waa 0.72.Marka loo eego celceliska heerka qiimaha ee Juun 2023, ethylene ayaa xisaabisa qiyaastii 37% qiimaha ethylene ku salaysan vinyl acetate, halka glacial acetic acid ay ka dhigan tahay 45%.Sidaa darteed, saameynta qiimaha, isbeddelka qiimaha glacial acetic acid wuxuu leeyahay saameynta ugu weyn ee isbeddelka qiimaha ethylene oo ku salaysan vinyl acetate, oo ay ku xigto ethylene.Marka la eego saameynta qiimaha calcium carbide ee habka vinyl acetate, kharashka calcium carbide ee habka calcium carbide vinyl acetate wuxuu xisaabiyaa qiyaastii 47%, iyo kharashka glacial acetic acid ee habka calcium carbide vinyl acetate wuxuu xisaabiyaa qiyaastii 35% .Sidaa darteed, habka calcium carbide ee vinyl acetate, isbeddelka qiimaha calcium carbide wuxuu saameyn weyn ku leeyahay qiimaha.Tani waxay si weyn uga duwan tahay saameynta kharashka habka ethylene.

Marka labaad, hoos u dhaca alaabta ceeriin ee ethylene iyo glacial acetic acid ayaa ahaa mid aad u weyn, taasoo keentay hoos u dhac weyn oo ku yimid qiimaha.Sanadkii la soo dhaafay, qiimaha CFR Waqooyi Bari Aasiya ethylene ayaa hoos u dhacay 33%, iyo qiimaha glacial acetic acid ayaa hoos u dhacay 32%.Si kastaba ha noqotee, qiimaha vinyl acetate ee ay soo saarto habka kaalshiyamka carbide waxaa inta badan xaddiday qiimaha kalsiyum carbide.Sannadkii la soo dhaafay, qiimaha kaarbiid-ka kaalshiyamku waxa uu hoos u dhacay 25% isugeyn.Sidaa darteed, marka laga eego aragtida laba hab oo wax soo saar oo kala duwan, qiimaha alaabta ceeriin ee vinyl acetate ee ay soo saarto habka ethylene ayaa si weyn hoos ugu dhacay, dhimista kharashka ayaa ka weyn habka calcium carbide.

Inkasta oo qiimaha vinyl acetate uu hoos u dhacay, hoos u dhaciisu maaha mid muhiim u ah kiimikooyinka kale.Marka loo eego xisaabinta, sannadkii hore, qiimaha vinyl acetate ayaa hoos u dhacay 59%, taas oo u muuqan karta mid muhiim ah, laakiin kiimikooyinka kale waxay la kulmeen hoos u dhac weyn.Xaaladda daciifka ah ee hadda jirta ee suuqa kiimikada Shiinaha way adag tahay in asal ahaan la beddelo.Waxaa la filayaa in mustaqbalka, ay jirto suurtogalnimo sare oo ah in faa'iidada wax soo saarka ee suuqa macaamiisha dhamaadka ah, gaar ahaan alaabooyinka sida khamriga polyvinyl iyo EVA, lagu hayn doono iyada oo la cadaadiyo faa'iidada vinyl acetate.

Waxaa jira isku dheelitir la'aan qiimo weyn leh oo ku jirta silsiladda warshadaha kiimikada ee hadda, iyo alaabooyin badan ayaa ku jira xaalad qiimo sare leh laakiin suuqa macaamiisha oo gaabis ah, taasoo keentay dhaqaalahooda wax soo saar liita.Si kastaba ha ahaatee, inkasta oo ay soo food saartay dhibaatooyin, suuqa vinyl acetate ayaa sii waday heer sare oo faa'iido, inta badan sababtoo ah saamiga kala duwan ee kharashka alaabta ceeriin ee habka wax soo saarka iyo hoos u dhigista qiimaha ay sababtay hoos u dhaca qiimaha alaabta ceeriin.Si kastaba ha ahaatee, xaaladda daciifka ah ee suuqa kiimikada mustaqbalka ee Shiinaha way adag tahay in asal ahaan la beddelo.Waxaa la filayaa in mustaqbalka, ay jirto suurtogalnimo sare oo ah in faa'iidada wax soo saarka ee suuqa macaamiisha dhamaadka ah, gaar ahaan alaabooyinka sida khamriga polyvinyl iyo EVA, lagu hayn doono iyada oo la cadaadiyo faa'iidada vinyl acetate.
