Ikhonkco leshishini leDMF

I-DMF (igama lekhemikhali i-N, N-dimethylformamide) yi-organic compound kunye ne-chemical formula C3H7NO, i-liquid engenambala kunye ne-transparent.I-DMF yenye yeemveliso ezinexabiso eliphezulu elongezelelweyo kwezoqoqosho kwikhonkco leshishini lemichiza yamalahle, kwaye zombini ziyimichiza ekrwada enezinto ezininzi ezisetyenziswayo kunye ne-solvent egqwesileyo enoluhlu olubanzi losetyenziso.I-DMF isetyenziswa kakhulu kwi-polyurethane (i-PU paste), i-electronics, i-fiber eyenziwe, i-pharmaceutical and food additive industries, njl njl. I-DMF inokuxutywa namanzi kunye neninzi ye-solvents eziphilayo.

Ubume bophuhliso loshishino lweDMF

Ukusuka kwicala lokubonelela nge-DMF yasekhaya, unikezelo luyatshintsha.Ngokwezibalo, ngo-2021, amandla okuvelisa i-DMF yasekhaya yi-870,000 yeetoni, imveliso yi-659,800 yeetoni, kwaye izinga lokuguqulwa kwamandla yi-75.84%.Xa kuthelekiswa no-2020, ishishini leDMF ngo-2021 linomthamo ophantsi, imveliso ephezulu kunye nokusetyenziswa kwamandla aphezulu.

Umthombo: ulwazi loluntu

Ukusuka kwicala lemfuno, ukusetyenziswa okubonakalayo kwe-DMF kukhula kancinci kwaye ngokuthe ngcembe kwi-2017-2019, kwaye ukusetyenziswa kwe-DMF kuncipha kakhulu ngo-2020 ngenxa yempembelelo yesibetho esitsha sesithsaba, kunye nokusetyenziswa okubonakalayo kolu shishino kuthatha ngo-2021. Ngokwezibalo, ukusetyenziswa okubonakalayo koshishino lweDMF e-China ngo-2021 yi-529,500 yeetoni, ukuya kwi-6.13% ngonyaka.

Umthombo: Ukuqokelelwa kolwazi loluntu

Ngokumalunga nolwakhiwo lwemfuno esezantsi, intlama yeyona ndawo isetyenziswayo.Ngokwezibalo, ngo-2021 iChina i-DMF yesakhiwo semfuno esezantsi, incama ye-PU sesona sicelo sikhulu se-DMF, esibalelwa kwi-59%, imfuno ye-terminal yeebhegi, iimpahla, izihlangu kunye neminqwazi kunye namanye amashishini, ishishini le-terminal likhule ngakumbi.

Ngowama-2021 eTshayina iDMF icandelo lezicelo zokwahlulwahlulwa kweendawo ezixeliweyo

Ubume bokungenisa kunye nokuthumela ngaphandle kwe-DMF

"N,N-dimethylformamide" ikhowudi yamasiko "29241910".Ukusuka kwimeko yokungenisa kunye nokuthumela ngaphandle, i-China ye-DMF ye-industry overcapacity, i-exports inkulu kakhulu kunempahla ethunyelwa ngaphandle, i-2021 amaxabiso e-DMF anyuke ngokukhawuleza, ixabiso le-export yase-China liye lanyuka.Ngokwezibalo, kwi-2021, inani lokuthumela ngaphandle kwe-DMF yaseTshayina li-131,400 yeetoni, imali yokuthumela ngaphandle i-229 yezigidi zeedola zaseMelika.

Ngokuphathelene nokuhanjiswa kwempahla kumazwe angaphandle, i-95.06% yobungakanani bokuthunyelwa kwe-DFM yaseTshayina ise-Asia.Ngokwezibalo, iindawo ezintlanu eziphezulu zokusasazwa kwe-DFM yase-China ngo-2021 yi-South Korea (30.72%), i-Japan (22.09%), i-Indiya (i-11.07%), i-Taiwan, i-China (11.07%) kunye ne-Vietnam (9.08%).

Ipateni yokhuphiswano loshishino lweDMF

Ngokubhekiselele kwipatheni yokhuphiswano (ngomthamo), ugxininiso loshishino luphezulu, kunye ne-CR3 ifikelela kwi-65%.Ngokwezibalo, ngo-2021, i-Hualu Hensheng yeyona nto ikhokelayo kwimveliso ye-DFM yasekhaya eneitoni ezingama-330,000 zomthamo wemveliso ye-DMF, kwaye ngoku ingoyena mvelisi mkhulu we-DMF emhlabeni, enesabelo semarike yasekhaya esingaphezulu kwe-33%.

Indlela yophuhliso lwexesha elizayo kwishishini leDMF

1, amaxabiso aqhubeka enyuka phezulu, okanye aya kulungiswa

Ukusukela ngo-2021, amaxabiso eDMF anyuke kakhulu.2021 amaxabiso DMF avareji 13,111 yuan / ton, phezulu 111.09% xa kuthelekiswa 2020. 5 February 2022, amaxabiso DMF kwaba 17,450 yuan / ton, kwinqanaba eliphezulu ngokwembali.Ukusasazeka kweDMF kuya kunyuka ukuya phezulu, kwaye kuyanda kakhulu.5 February 2022, DMF ukusasazeka kwaba 12,247 yuan / ton, kude kakhulu kwimbali umndilili wokusasaza inqanaba.

I-2, icala lokubonelela lilinganiselwe kwixesha elifutshane, imfuno ye-DMF yexesha elide iya kuqhubeka nokubuyisela

Ngo-2020, echatshazelwa ngubhubhani omtsha wesithsaba, ukusetyenziswa kweDMF kwehle kakhulu, kwaye uZhejiang Jiangshan uphuma kwiitoni ezingama-180,000 zomthamo wokuvelisa kwicala lokubonelela ngempembelelo ethile.Ngo-2021, impembelelo yobhubhani wasekhaya yaba buthathaka, izihlangu, iibhegi, iimpahla kunye nemveliso yefenitshala ifuna ukubuyiswa, imfuno yokuncamathisela yePU yaphuculwa, imfuno yeDMF ikhule ngokufanelekileyo, ukusetyenziswa kweDMF okubonakalayo ngonyaka kweetoni ezingama-529,500, ukwanda kwe-6.13% ngonyaka- ngonyaka.6.13% ukukhula konyaka nonyaka.Njengoko impembelelo yobhubhani omtsha wesithsaba ngokuthe ngcembe iyancipha, uqoqosho lwehlabathi lwazisa ukuchacha, imfuno ye-DMF iya kuqhubeka nokuchacha, imveliso ye-DMF kulindeleke ukuba ikhule ngokuthe ngcembe ngo-2022 nango-2023.
