1. Isbeddelka qiimaha suuqa iyo isbeddellada

rubuci saddexaad ee 2024, suuqa gudaha ee bisphenol A waxa uu la kulmay isbedbedel joogto ah oo ka dhex jira inta u dhaxaysa, oo aakhirkii muujiyay isbeddel caajis ah. Celceliska qiimaha suuqa ee rubucii wuxuu ahaa 9889 yuan/ton, koror ah 1.93% marka loo eego rubuci hore, isagoo gaaray 187 yuan/ton. Isbeddelkan waxaa inta badan loo aaneynayaa baahida daciifka ah ee xilliga caadiga ah ee ka baxsan (Juulaay iyo Agoosto), iyo sidoo kale kororka xiritaanka iyo dayactirka xilliyeed ee warshadaha xabagta epoxy, taasoo keentay baahida suuqa oo xaddidan iyo soosaarayaasha ay la kulmaan dhibaatooyinka maraakiibta. Inkasta oo kharashyo badan ay jiraan, khasaaraha warshaduhu waa uu sii kordhay, waxaana jirta meel xaddidan oo alaab-qeybiyeyaasha ay ku sameyn karaan tanaasul. Sicirka suuqa ayaa had iyo jeer isu bedbeddela inta u dhaxaysa 9800-10000 yuan/ton ee Bariga Shiinaha. Gelida "Golden Sagaal", hoos u dhigista dayactirka iyo kororka sahayda ayaa sii xumeeyay xaaladda saadka ee suuqa. In kasta oo ay jirto taageerada kharashka, qiimaha bisphenol A weli way adag tahay in la dejiyo, iyo ifafaalaha xilliga ugu sarreeya ee gaabis ah waa wax iska cad.

2. Balaadhinta awoodda iyo kobaca wax soo saarka

Saddexdii bilood ee la soo dhaafay, awoodda wax-soo-saarka gudaha ee bisphenol A waxay gaadhay 5.835 milyan tan, korodhka 240000 tan marka la barbar dhigo rubuci labaad, inta badan laga soo bilaabo komishanka warshadda Huizhou II ee koonfurta Shiinaha. Dhanka wax-soo-saarka, wax-soo-saarka rubuci saddexaad wuxuu ahaa 971900 tan, koror ah 7.12% marka loo eego rubucii hore, isagoo gaaray 64600 tan. Isbeddelkan korriinka ah waxaa loo aaneynayaa saameynta laba-geesoodka ah ee qalabka cusub ee la geliyo shaqada iyo dayactirka qalabka oo yaraaday, taasoo keentay koror joogto ah ee wax soo saarka bisphenol A gudaha.

3. Warshadaha hoose waxay bilaabeen inay kordhiyaan wax soo saarka

In kasta oo aan awoodda wax-soo-saarka cusub aan la hawlgelin rubuci saddexaad, culaysyada hawlgalka ee kombuyuutarrada hoose iyo warshadaha resin epoxy ayaa kordhay. Celceliska culeyska shaqada ee warshadaha PC waa 78.47%, koror ah 3.59% marka loo eego muddadii hore; Celceliska culeyska shaqada ee warshadaha xabagta epoxy waa 53.95%, koror 3.91% bishii. Tani waxay muujinaysaa in baahida loo qabo bisphenol A ee labada warshadood ee hoose ay kordheen, iyagoo siinaya xoogaa taageero ah qiimaha suuqa.

4. Cadaadiska kharashka oo kordhay iyo khasaaraha warshadaha

Saddexdii bilood ee la soo dhaafay, qiimaha celceliska aragtida ee bisphenol A warshadaha ayaa kordhay ilaa 11078 yuan/ton, bishiiba koror dhan 3.44%, badiyaa ay ugu wacan tahay sare u kaca qiimaha phenol alaabta ceeriin. Si kastaba ha ahaatee, celceliska faa'iidada warshadaha ayaa hoos ugu dhacday -1138 yuan / ton, hoos u dhac 7.88% marka loo eego xilligii hore, taas oo muujinaysa cadaadiska qiimaha weyn ee warshadaha iyo sii xumaanshaha xaaladda khasaaraha. Inkasta oo hoos u dhaca qiimaha acetone ee alaabta ceeriin la dhimay, qiimaha guud weli kuma habboona faa'iidada warshadaha.

5. Saadaasha suuqa ee rubuci afraad

1) Aragtida qiimaha

Waxa la filayaa in rubuca afraad ay yaraato dayactirka warshada phenol ketone, oo ay weheliso imaanshaha badeecadaha laga soo dejiyo dekeda, waxa kor u kaca saadka phenol-ka ee suuqa, waxaana suurtogal ah in qiimo dhimis uu ku yimaado. . Suuqa acetone, dhanka kale, waxaa la filayaa in uu la kulmo isbedel hoose oo qiimaha sahayda badan awgeed. Isbeddellada ku yimaadda sahayda ketones-ka phenolic-ga ayaa xukumi doona isbeddelka suuqa oo ay cadaadis gaar ah ku saari doonaan qiimaha bisphenol A.

2) Saadaasha dhinaca sahayda

Waxaa jira qorshooyin dayactir oo yar oo loogu talagalay dhirta bisphenol A ee gudaha rubuci afraad, iyada oo tiro yar oo dayactir ah lagu sameeyo aagagga Changshu iyo Ningbo. Isla mar ahaantaana, waxaa jira rajooyin la filayo in la sii daayo awoodda wax soo saarka cusub ee gobolka Shandong, waxaana la filayaa in sahayda bisphenol A ay sii ahaan doonto mid aad u badan rubuci afaraad.

3) Muuqaalka dhinaca baahida

Howlaha dayactirka ee warshadaha hoose waa ay yaraadeen, laakiin warshadaha xabagta epoxy waxaa saameeya iska hor imaadyada saadka iyo baahida, waxaana la filayaa in wax soo saarka uu ahaado mid aad u hooseeya. Inkasta oo ay jiraan rajooyin ah in qalab cusub lagu rakibo warshadaha PC, waa in fiiro gaar ah loo yeesho horumarka wax soo saarka dhabta ah iyo saameynta qorshooyinka dayactirka ee culeyska hawlgalka. Guud ahaan, baahida hoose uma badna inay la kulmaan kobac weyn rubuci afraad.

Iyada oo ku saleysan falanqaynta dhamaystiran ee qiimaha, sahayda, iyo baahida, waxa la filayaa in suuqa bisphenol A uu si daciif ah u shaqayn doono rubuci afraad. Taageerada kharashku way daciiftay, rajada sahaydu way korodhay, baahida hoosena way adagtahay in si wayn loo hagaajiyo. Xaaladda luminta warshadaha ayaa laga yaabaa inay sii socoto ama xitaa way sii korodho. Sidaa darteed, waxaa lagama maarmaan ah in si dhow loola socdo dhimista culeyska aan la qorsheyn iyo howlaha dayactirka ee warshadaha si loola tacaalo khataraha isbeddelka suuqa ee iman kara.
