Kutshanje, yasekhaya iyonkeimethyl methacrylateimakethi iqhubekile nokuba buthathaka, kwaye abasebenzisi bokugqibela abasezantsi bagcina imisebenzi yokuthenga nje.Ngenxa yexabiso lemakethi ye-methyl methacrylate yakutsha nje liyaqhubeka ukuba phantsi, lihamba kufutshane nexabiso labavelisi abakhulu basekhaya be-methyl methacrylate.Ngaphantsi koxinzelelo lweendleko, bagcina umkhwa wokugqiba imisebenzi, kwaye kwakunzima ukufumana imithombo yexabiso eliphantsi lempahla kwiimarike.Methyl methacrylate eMpuma China yaba RMB10,700-10,800/ton.Urhwebo oluqhelekileyo lwe-methyl methacrylate eMzantsi China lwalusondele kwi-RMB11,100-11,300 / mt.

Kutshanje kuphakathi kwaye ekupheleni kuka-Agasti, kufutshane kwixesha lentengiso yemveli ye-methyl methacrylate yasekhaya, yasekhaya methyl methacrylate ezantsi umoya utyalo-mali jikelele jikelele iyaqhubeka kufuneka kuphela ukuthenga, musa ukuvala ukuba ekupheleni kuka-Agasti nasekuqaleni kukaSeptemba, yasekhaya. Itheyibhile ye-methyl methacrylate esezantsi yokuthenga i-terminal iya kuba nophuculo oluthile, umoya wokuthengwa kwemarike unokuphucuka kancinci.

Ukugcinwa kwezixhobo ezithile okanye ukuqalisa kwakhona, uluhlu lwentengiso luninzi kakhulu

Kwicala lokubonelela, inkqubo ye-C4 iye yalahlekelwa yimali ngokuqhubekayo ukususela kulo nyaka, i-C4 indlela yokuqaliswa kwezixhobo zokuqalisa umthwalo iphantsi, ngakumbi ngo-Agasti emva kwe-Huizhou Mitsubishi kunye ne-Roma Ukugcinwa kweMichiza yokupaka, umthwalo wokuqalisa uphantsi njenge-5. %.Nangona kunjalo, itekhnoloji ye-acetone cyanohydrin isalawula, ikakhulu igxile kwimpuma yeTshayina.Nangona kunjalo, ikwanqunyelwe ngumthwalo wokuqalisa we-acrylonitrile.Izinga lokuqalisa indlela ye-acetone cyanohydrin yi-64%.ngo-Agasti, nangona iseti yezixhobo zeSearborn iyekile ukugcinwa, kunye nokwanda komthwalo emva kokugcinwa komgca wokuqala we-ZPMC II kunye nokuqaliswa okuzinzileyo komgca wezixhobo ze-Jiankun, unikezelo lulonke e-East China ngokucacileyo. ikhululekile, kwaye inxalenye yayo ingena kwimarike yaseShandong, enempembelelo ethile ekuthengisweni kwendawo yaseShandong.Okwangoku, umahluko wexabiso phakathi kwemimandla uncinci kakhulu.

Iqondo lobushushu elisezantsi ezantsi kwi-off-season, okanye ukuphucula kwisiqingatha sesibini sonyaka

Ngenxa yokunqongophala kwemeko yezoqoqosho ekusetyenzisweni kweemarike kunye nokunyuka kwamaqondo obushushu aphezulu exesheni ngo-Agasti, bekukho ukuphucuka okuncinci kwimfuno yoshishino lwasekhaya.Nangona kunjalo, kufanelekile ukukhankanya ukuba i-MMA inyuse umlinganiselo wokuthengwa kwe-MMA ngabasebenzisi bebhodi esezantsi ukuze badlale indima ethile yenkxaso kwimarike.Ngesiqhelo, uninzi lwabasebenzisi bebhodi yokugalela baya kuthenga zombini iMMA kunye nemathiriyeli esetyenzisiweyo kunye nemveliso, ngokuqhelekileyo ixabiso lezinto ezisetyenzisiweyo lisezantsi kakhulu kune-MMA, kodwa incinci yangoku phakathi kwe-MMA monoma kunye nemathiriyeli ehlaziyiweyo.I-ACR ngenxa yenzuzo ephantsi ekhoyo ngoku, ukuthengwa koshishino lwemathiriyeli ekrwada ukugcina imfuno efanelekileyo;imboni ye-emulsion resin ngenxa yezinye iimveliso zemathiriyeli ekrwada ziyaqhubeka ukuya kwelinye icala ezantsi, abathengi balumke ukuthenga.

Kwicala lokuthumela ngaphandle, nangona amaxabiso asekhaya ehle, umahluko wexabiso phakathi kwangaphakathi nangaphandle uye wacutheka.Ukongeza, ukuthunyelwa kwamanye amazwe kwasekhaya kwakuseIndiya nakwi-mpuma ye-Asia ngenxa yemozulu yendawo kunye neenkxalabo zezoqoqosho kummandla wehlabathi.

Phakathi ukuya ekupheleni kuka-Agasti, imeko yokushisa ephezulu kwezinye iindawo kwixesha elidlulileyo inokunciphisa ngokuthe ngcembe.Ngexesha elidlulileyo, ngenxa yobushushu obuphezulu, abavelisi bokugqibela be-methyl methacrylate ngokwabo banokubuyela ngokuthe ngcembe ekusebenzeni okuqhelekileyo kokusebenza okuqhelekileyo.Ke ngoko, inqanaba lemfuno yasekhaya linokuba nomkhwa othile wokunyusa.

Inkxaso yethutyana evela kwiindleko

Ilahleko ezinzileyo yeC4 ithintela inkuthazo yamashishini ukuba aqale ngaphandle kohlalutyo oluthile.Okwangoku, inzuzo ye-acetone cyanohydrin indlela ye-acetone cyanohydrin indlela.Inzuzo yethiyori yereferensi ye-acetone cyanohydrin indlela yamashishini yi-2,440 yuan / ton, kodwa kuqwalaselwa iindleko ezahlukeneyo zokubala izixhobo ezidibeneyo ezixhasayo kunye nezixhobo ezizimeleyo, ezifana nemveliso enxulumene ne-acrylonitrile inengeniso encinci, inzuzo yekhonkco leshishini le-accounting ichanekile izixhobo zeMMA. Ukuqala kwakhona kuneqondo elahlukileyo leempembelelo, ezifana neendleko eziphezulu ze-methanol ammonia oxidation indlela yokuvelisa i-hydrocyanic acid.

Nangona kunjalo, ngomthamo ogqithisiweyo we-methyl methacrylate yasekhaya, unikezelo lwabavelisi kwiindawo zentengiso yasekhaya ye-methyl methacrylate luzinzile, lubonelela ngeemeko ezisebenzayo kubasebenzisi bokuphela komsinga kwimarike yasekhaya ye-methyl methacrylate.Iyonke intengiso yasekhaya ye-methyl methacrylate zezekhontrakthi kunye nemarike yokuthengisa iyonke.Ngenxa yobuninzi bamanqanaba obonelelo, abasebenzisi bokugqibela abasezantsi ikakhulu basebenzisa iikhontrakthi zabo, kunye neendawo zokuthengisa zokwenyani ezigcina iiodolo zabo zokuthenga kuphela.

Kulindeleke ukuba inqanaba leemfuno zemarike yasekhaya ye-methyl methacrylate inokwenyuka ngokuthe ngcembe ukusuka ekupheleni kuka-Agasti ukuya kuSeptemba, kwaye inqanaba lemfuno yomyalelo we-terminal esezantsi inokunyusa ukusuka ngoJulayi ukuya ekuqaleni kuka-Agasti, kunye nokuthengwa kwe-odolo yangempela gcina umsebenzi wayo wokuthenga ngokungqongqo.Ukurhweba kwexesha elifutshane kuyacetyiswa, ukulinda isikhokelo esicacileyo solwazi.
