Dhawaan, guud ahaan gudahamethyl methacrylatesuuqa ayaa sii waday inuu daciifo, iyo isticmaalayaasha ugu dambeeya inta badan waxay sii wadaan kaliya hawlgallada wax iibsiga. Sababtoo ah methacrylate methyl methacrylate ee gudaha ee dhawaa qiimaha suuqa ayaa sii socda inuu hooseeyo, isagoo ku dhow khadka qiimaha wax soosaarayaasha methacrylate methyl ee gudaha. Marka la eego cadaadiska kharashka, waxay sii wadaan isbeddelka hawlaha dhamaystirka, wayna adkayd in la helo ilo qiimo jaban oo alaab ah suuqa. Methyl methacrylate ee Bariga Shiinaha wuxuu ahaa RMB10,700-10,800/ton. Ganacsiga guud ee methyl methacrylate ee Koonfurta Shiinaha wuxuu ku dhowaa RMB11,100-11,300/mt.

Dhawaan waa bartamihii iyo dabayaaqadii Agoosto, oo ku dhow xilliga iibka dhaqameed ee methyl methacrylate gudaha, gudaha methyl methacrylate hoose ee jawiga maalgashiga guud ee suuqa guud ayaa sii socda oo kaliya in la iibsado, ha ka saarin in dhammaadka Agoosto iyo horraantii Sebtembar, miiska dalabka iibka ee methacrylate gudaha ee methacrylate gudaha wuxuu yeelan doonaa xoogaa horumar ah, jawiga iibka suuqa ayaa laga yaabaa inuu si tartiib tartiib ah u fiicnaado.

Qaar ka mid ah dayactirka qalabka ama dib u bilaabma, alaabada suuqa ayaa aad u badan

Dhinaca sahayda, habka C4 ayaa si joogto ah u luminaya lacagta tan iyo sanadkan, C4 habka qalabka bilawga ah ee culeyska ayaa hooseeya, gaar ahaan Agoosto ka dib markii Huizhou Mitsubishi iyo Roma Kiimikada dayactirka baarkinka, culeyska bilawga ah sida ugu hooseeya 5%. Si kastaba ha noqotee, tignoolajiyada acetone cyanohydrin ayaa wali xukuma, inta badan waxay ku badan tahay bariga Shiinaha. Si kastaba ha ahaatee, waxaa sidoo kale xaddiday culeyska bilawga ah ee acrylonitrile. Heerka bilawga ah ee habka cyanohydrin acetone waa 64%. in August, inkastoo set oo ah qalabka Searborn ayaa joojiyay dayactirka, iyadoo kororka load ka dib dayactirka ee line ugu horeysay ee ZPMC II iyo bilowga xasiloon ee line a qalabka Jiankun, sahayda guud ee Bariga Shiinaha waa iska cad dabacsan, iyo qayb ka mid ah waxaa qulqulaya suuqa Shandong, taas oo uu leeyahay saamayn qaar ka mid ah iibka kaalinta Shandong. Waqtigan xaadirka ah, farqiga u dhexeeya qiimaha gobollada waa mid aad u yar.

Hoos-u-dhac heerkul sare oo ka baxsan xilli-ciyaareedka, ama kor u kaca qaybta labaad ee sanadka

Kalsooni la'aanta jawiga dhaqaale ee isticmaalka suuqa iyo heerkulka sare ee xilliga ka baxsan ee Agoosto, waxaa jiray horumar yar oo baahida warshadaha gudaha ee gudaha. Si kastaba ha ahaatee, waxaa mudan in la sheego in MMA ay kordhisay saamiga iibsashada MMA ee isticmaalayaasha guddiga shubista si ay u ciyaaraan door taageero oo gaar ah suuqa. Caadi ahaan, inta badan isticmaalayaasha guddiga shubista ayaa iibsan doona MMA iyo walxo dib loo warshadeeyay oo ay la socdaan wax soo saarka, badiyaa qiimaha alaabta dib loo warshadeeyay aad ayuu uga hooseeyaa MMA, laakiin kan hadda yar ee u dhexeeya MMA monomer iyo walxaha dib loo warshadeeyay. ACR sababtoo ah faa'iidada liidata ee hadda jirta, iibsashada warshadaha ee alaabta ceeriin si loo ilaaliyo baahida kaliya; Warshadaha resin emulsion oo ay ugu wacan tahay alaabada kale ee ceyriinka ah waxay ku sii socdaan hoos hal dhinac, iibsadayaashu way ka taxaddaraan inay iibsadaan.

Dhinaca dhoofinta, inkasta oo qiimaha waddanku hoos u dhacay, farqiga qiimaha u dhexeeya gudaha iyo dibadda ayaa hoos u dhacay. Intaa waxaa dheer, dhoofinta gudaha waxay ahayd Hindiya iyo Koonfur-bari Aasiya sababtoo ah cimilada maxalliga ah iyo welwelka dhaqaale ee gobolka adduunka.

Bartamaha ilaa dabayaaqada Agoosto, xaalada heerkulka sare ee gobolada qaar waagii hore ayaa si tartiib tartiib ah u yarayn kara. Muddo ka hor, heerkulka sare awgeed, soo-saareyaasha methyl methacrylate laftooda ayaa laga yaabaa inay si tartiib tartiib ah ugu soo laabtaan hawlgalkii caadiga ahaa ee caadiga ahaa. Sidaa darteed, heerka dalabka gudaha ayaa laga yaabaa inuu yeesho isbeddel gaar ah oo kor loogu qaadayo.

Taageerada ku meel gaadhka ah ee kharashka

Khasaaraha joogtada ah ee C4 ayaa xannibaya dhiirigelinta ganacsiyada si ay u bilaabaan iyada oo aan la falanqaynin gaar ah. Waqtigan xaadirka ah, faa'iidada habka acetone cyanohydrin ee habka acetone cyanohydrin. The faa'iido teoretical tixraaca ee shirkadaha habka cyanohydrin acetone waa 2,440 yuan / ton, laakiin la tixgelinayo xisaabaadka kala duwan ee xisaabaadka ee qalab taageero isku dhafan iyo qalab madax-bannaan, sida acrylonitrile alaabta la xidhiidha waa ka yar faa'iido, faa'iidada ay silsilad warshadaha xisaabaadka waa sax ah qalabka MMA bilaabi-up sidoo kale uu leeyahay heerka kala duwan ee saamaynta, sida qiimaha sare ee methanol acid.

Si kastaba ha ahaatee, iyada oo leh awoodda dheeraadka ah ee methyl methacrylate gudaha, sahayda wax-soo-saarka ee aagagga suuqa methacrylate ee ugu weyn ee gudaha waa mid deggan, taasoo bixisa shuruudo wax ku ool ah isticmaalayaasha dhamaadka suuqa guud ee methacrylate gudaha gudaha. Guud ahaan iibka gudaha ee methyl methacrylate waa inta badan qandaraasle iyo guud ahaan suuqa tafaariiqda. Sababo la xiriira heerarka saadka ee badan, isticmaalayaasha dhamaadka-hoose waxay inta badan cunaan qandaraasyadooda, iyada oo bakhaarrada tafaariiqda ah ee dhabta ah ay ilaalinayaan dalabaadkooda wax iibsiga oo keliya.

Waxaa la filayaa in guud ahaan heerka baahida suuqa ee methyl methacrylate uu si tartiib tartiib ah u kordho laga bilaabo dhamaadka Agoosto ilaa Sebtembar, iyo heerka dalabka dhabta ah ee dalabka marinnada hoose ayaa laga yaabaa inuu kordho Julaay ilaa horraanta Agoosto, iyo iibsashada dhabta ah ee suuqu waxay sii wadi doontaa hawlgalkeeda iibsiga baahida adag. Ganacsiga muddada-gaaban ayaa lagula talinayaa, iyadoo la sugayo hagidda macluumaadka cad.
