Qiimaha suuqa kiimikada ayaa hoos u sii socday ilaa nus sano.Hoos u dhaca noocan oo kale ah, halka qiimaha saliidda uu weli sarreeyo, ayaa keentay isu dheelitir la'aanta qiimaha inta badan isku xirka silsiladda warshadaha kiimikada.Terminal badan oo ku jira silsiladda warshadaha, cadaadiska weyn ee kharashka silsiladda warshadaha.Sidaa darteed, badeecooyin badan oo kiimiko ah ayaa hadda ku sugan xaalad qaali ah laakiin suuqa macaamiisha oo gaabis ah, taasoo keentay dhaqaala xumo wax soo saar kiimiko ah oo badan.
Qiimaha suuqa ee vinyl acetate ayaa sidoo kale hoos u dhacay.Sanadihii la soo dhaafay, qiimaha suuqa ee vinyl acetate wuxuu hoos uga dhacay 14862 yuan/ton bishii Juun 2022 ilaa Juun 2023, isagoo si joogto ah hoos ugu dhacayay ku dhawaad ​​hal sano, iyadoo qiimaha ugu hooseeya uu hoos ugu dhacay 5990 yuan/ton.Laga soo bilaabo isbeddellada qiimaha dhowrkii sano ee la soo dhaafay, qiimaha ugu hooseeya ee taariikhda wuxuu soo muuqday Abriil 2020, qiimaha ugu hooseeya wuxuu soo muuqday 5115 yuan/ton, qiimaha ugu sarreeya wuxuu soo muuqday Noofambar 2021, qiimaha ugu sarreeyana wuxuu u muuqday 16727 yuan/ton.

Inkasta oo qiimaha vinyl acetate uu hoos u dhacay sanad isku xigta, faa'iidada wax soo saarka ee vinyl acetate ayaa weli ah mid sare iyo dhaqaalaha wax soo saarka waa mid wanaagsan.Maxay vinyl acetate u ilaalin kartaa heer sare oo barwaaqo ah?
Nidaamyada wax soo saarka kala duwan ee vinyl acetate waxay keenaan faa'iidooyin iyo khasaarooyin kala duwan
Marka loo eego isbeddelka heerka faa'iidada faa'iidada vinyl acetate ee ay soo saarto habka ethylene, heerka faa'iidada faa'iidada vinyl acetate ee ay soo saartay habka ethylene ayaa had iyo jeer ku jirtay xaalad faa'iido leh dhowrkii sano ee la soo dhaafay, heerka faa'iidada ugu sarreeya ayaa gaadhay 50% ama ka badan. celceliska heerka faa'iidada waa qiyaastii 15%.Waxaa la arki karaa in ethylene ku salaysan vinyl acetate ay ahayd wax soo saar faa'iido leh labadii sano ee la soo dhaafay, oo leh barwaaqo guud oo wanaagsan iyo faa'iido xasilloon.

Marka loo eego habka calcium carbide vinyl acetate, labadii sano ee la soo dhaafay, marka laga reebo faa'iidada la taaban karo laga bilaabo Maarso 2022 ilaa Luulyo 2022, dhammaan xilliyada kale waxay ku jireen xaalad khasaare ah.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.Waxaa la arki karaa in barwaaqada habka calcium carbide ee vinyl acetate ay liidato, xaaladda guudna waxay muujinaysaa khasaare.

Waxaa la arki karaa in aysan ahayn dhacdo caadi ah oo loogu talagalay vinyl acetate in ay noqoto heer faa'iido sare leh.Kaliya habka ethylene ee wax soo saarka vinyl acetate ayaa hadda ku jira xaalad faa'iido leh, halka habka carbide uu had iyo jeer ku jiray xaalad khasaare ah dhowrkii sano ee la soo dhaafay.
Falanqaynta ilaalinta faa'iidada sare ee wax soo saarka vinyl acetate ku salaysan ethylene
1. Saamiga kharashka alaabta ceeriin way ku kala duwan yihiin hababka wax soo saarka ee kala duwan.Soosaarka vinyl acetate ee ku salaysan ethylene, isticmaalka unugga ethylene waa 0.35 iyo isticmaalka unugga acetic acid waa 0.72.Marka loo eego celceliska qiimaha bishii Juun 2023, saamiga ethylene ee wax soo saarka vinyl acetate ee ethylene ku salaysan waa 37%, halka glacial acetic acid uu yahay 45%.Sidaa darteed, isbedbeddelka qiimaha glacial acetic acid wuxuu leeyahay saameynta ugu weyn ee isbeddelka kharashka ee wax soo saarka vinyl acetate ee ethylene, oo ay ku xigto ethylene.
Sida kharashka habka carbide calcium ee vinyl acetate, calcium carbide xisaabiyaa ilaa 47% kharashka habka calcium carbide ee vinyl acetate, iyo glacial acetic acid xisaabiyaa qiyaastii 35% kharashka habka calcium carbide for vinyl acetate.Sidaa darteed, habka calcium carbide ee vinyl acetate, isbeddelka qiimaha calcium carbide ayaa saameyn weyn ku leh kharashka, taas oo aad uga duwan saameynta kharashka habka ethylene.
2. Hoos u dhaca weyn ee alaabta ceeriin ee ethylene iyo glacial acetic acid ayaa keentay hoos u dhac weyn oo ku yimid kharashyada.Marka loo eego xogta la xidhiidha, sannadkii 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 ahaatee, qiimaha wax soo saarka ee vinyl acetate iyadoo la isticmaalayo habka calcium carbide inta badan waxaa xaddiday qiimaha calcium carbide.Sannadkii hore, qiimaha kaarbiid-ka calcium ayaa hoos u dhacay 25%.
Sidaa darteed, marka laga eego aragtida laba hab oo wax soo saar oo kala duwan, qiimaha alaabta ceeriin ee habka ethylene vinyl acetate ayaa si weyn hoos ugu dhacay, dhimista kharashka ayaa ka weyn habka calcium carbide.

3. Inkasta oo qiimaha vinyl acetate uu hoos u dhacay, hoos u dhacu maaha mid la mid ah kiimikooyinka kale.Sannadkii hore, qiimaha vinyl acetate ayaa hoos u dhacay 59%, taas oo u muuqata hoos u dhac weyn, laakiin qiimaha kiimikooyinka kale ayaa hoos u dhacay xitaa in ka badan.
Vinyl acetate waxay had iyo jeer ilaalisay faa'iido gaar ah, inta badan sababtoo ah dhimista kharashka ee ay sababtay hoos u dhaca qiimaha alaabta ceeriin, halkii ay ka taageeri lahayd suuqa macaamiisha ee qiimaheeda.Tani sidoo kale waa xaaladda hadda jirta ee gudbinta qiimaha ee silsiladda warshadaha vinyl acetate.Laga soo bilaabo xaaladda hadda jirta ee suuqa kiimikada ee Shiinaha ee muddada gaaban, way adagtahay in si aasaasi ah loo beddelo xaaladda daciifka ah ee suuqa kiimikada Shiinaha iyada oo aan la helin siyaasadaha kicinta suuqa macaamiisha ee ballaaran.Waxaa la filayaa in silsiladda qiimaha ee vinyl acetate ay sii wadi doonto ilaalinta macquulka gudbinta hoos u dhaca, waxaana la filayaa in faa'iidada wax soo saarka ee mustaqbalka dhammaadka suuqa macaamiisha, gaar ahaan alaabooyinka polyetylen iyo EV, lagu hayn doono iyada oo la dhimayo faa'iidada vinyl. acetate.
