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 eTshayina ngo-2021 ziitoni ezingama-529,500, phezulu. 6.13% unyaka nonyaka.

Umthombo: Ukuhlanganiswa 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 yesiphelo seebhegi, iimpahla, izihlangu kunye neminqwazi kunye namanye amashishini, ishishini lesiphelo likhulile.

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 ene-330,000 yeetoni 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.
