    I-N, i-N-Dimethylformamide (i-DMF) iyilwelo olucacileyo oluye lwasetyenziswa ngokubanzi kumashishini njenge-solvent, i-additive, okanye i-intermediate ngenxa yokungahambi kakuhle kwamanzi kunye nezona zinyibiliki zixhaphakileyo.

    I-Dimethylformamide isetyenziswa ngokuyintloko njenge-solvent ye-industrial.Izisombululo zeDimethylformamide zisetyenziselwa ukucubungula iifiber zepolymer, iifilimu, kunye nokwaleka komhlaba;ukuvumela ukusonteka lula kweefiber ze-acrylic;ukuvelisa i-enamels zocingo, kwaye njenge-crystallization medium kwishishini lamachiza.

    I-DMF ingasetyenziselwa i-formylation kunye ne-alkyllithium okanye i-Grignard reagents.

    Isetyenziswa njenge-reagent kwi-Bouveault aldehyde synthesis kunye nakwi-Vilsmeier-Haack reaction.Isebenza njenge-catalyst kwi-synthesis ye-acyl chlorides.Isetyenziselwa ukwahlula kunye nokucokisa ubukrwada kwirhasi yeolefin.I-DMF kunye ne-methylene chloride isebenza njengento yokususa ivanishi okanye i-lacquers.Ikwasetyenziswa ekwenzeni izinto zokuncamathelisa, iintsinga kunye neefilim.

    I-N, i-N-Dimethylformamide (i-DMF) i-solvent enezinga eliphantsi lokunyuka kwe-evaporation, iluncedo ekulungiseleleni izisombululo kunye neentlobo ezahlukeneyo ze-hydrophobic organic compounds ezisetyenziswa kwi-biology ye-molecular applications.

    I-N, i-N-Dimethylformamide yayisetyenziselwa i-solubilize i-crystals ye-MTT kwiimvavanyo ze-cell viability.

    Usetyenziso lwehlabathi jikelele lweDMF ngo-2001 lwalumalunga ne-285, 000 yeetoni zeemetric kwaye uninzi lwazo lwalusetyenziswa njengesinyibilikisi semizi-mveliso.

    INDLELA YOKUTHENGA KUTHI

    I-Chemwin inokubonelela ngoluhlu olubanzi lwee-hydrocarbons ezininzi kunye nezinyibilikisi zeekhemikhali kubathengi bamashishini.Ngaphambi koko, nceda ufunde olu lwazi lulandelayo olusisiseko malunga nokwenza ishishini nathi: 

    1. Ukhuseleko

    Ukhuseleko yeyona nto iphambili kuthi.Ukongeza ekunikeni abathengi ngolwazi malunga nokusetyenziswa ngokukhuselekileyo nokuhambelana nokusingqongileyo kweemveliso zethu, sikwazimisele ekuqinisekiseni ukuba imingcipheko yokhuseleko lwabasebenzi kunye neekontraka ziyathotywa ukuya kutsho kubuncinane obufanelekileyo nobunokwenzeka.Ngoko ke, sifuna ukuba umthengi aqinisekise ukuba imigangatho efanelekileyo yokukhutshwa kunye nokugcinwa kwemigangatho yokhuseleko idibene ngaphambi kokunikezelwa kwethu (nceda ubhekisele kwisihlomelo se-HSSE kwimimiselo jikelele kunye neemeko zokuthengisa ngezantsi).Iingcali zethu zeHSSE zinokubonelela ngesikhokelo kule migangatho.

    2. Indlela yokuhambisa

    Abathengi banokuodola kwaye bahambise iimveliso kwi-chemwin, okanye banokufumana iimveliso kwisityalo sethu sokuvelisa.Iindlela ezikhoyo zothutho ziquka iilori, uloliwe okanye uthutho lweendlela ezininzi (kuyasebenza iimeko ezahlukileyo).

    Kwimeko yeemfuno zabathengi, sinokucacisa iimfuno zeenqanawa okanye iitanki kwaye sisebenzise imigangatho ekhethekileyo yokhuseleko / ukuhlaziya kunye neemfuno.

    3. Ubuncinci bobungakanani bomyalelo

    Ukuba uthenga iimveliso kwiwebhusayithi yethu, ubungakanani obuncinci bomyalelo ziitoni ezingama-30.

    4.Intlawulo

    Indlela yokuhlawula eqhelekileyo itsalwa ngokuthe ngqo kwiintsuku ezingama-30 kwi-invoyisi.

    5. Amaxwebhu okuhanjiswa

    La maxwebhu alandelayo anikwe ngokuziswa ngakunye:

    · Ibhili yokuLading, i-CMR Waybill okanye olunye uxwebhu olufanelekileyo lwezothutho

    · Isatifikethi sokuHlalutya okanye ukuThobela (ukuba siyafuneka)

    · Amaxwebhu anxulumene neHSSE ngokuhambelana nemigaqo

    · Amaxwebhu ezinto eziqhelekileyo ngokuhambelana nemigaqo (ukuba kuyafuneka)
