Ukusetyenziswa kweeMveliso
Njengomsebenzi obalulekileyo weekhemikhali kunye ne-solvent esebenza kakuhle, i-dimethylformamide (DMF) isetyenziswa kakhulu kwi-polyurethane, i-acrylic, iyeza, i-pesticides, idayi, i-electronics kunye namanye amashishini. Isetyenziswa kakhulu kwimveliso yesikhumba esimanzi sokwenziwa njengento yokuhlamba kunye nokunyanga kwishishini le-polyurethane. Kwishishini lamachiza njenge-intermediates yeziyobisi zokwenziwa, ezisetyenziswa ngokubanzi kwimveliso ye-doxycycline, i-cortisone, iziyobisi ze-sulfonamide; Njenge-solvent kushishino lwefayibha ye-acrylic, isetyenziswa ikakhulu ukusonta okomileyo kwefiber ye-acrylic. Kwishishini le-pesticide ukuze kuhlanganiswe ukusebenza kakuhle okuphezulu kunye netyhefu ephantsi yokubulala izinambuzane; Kwishishini ledayi njengesinyibilikisi sedayi; Kwishishini lombane njengetoti yokubeka iinxalenye zokucima kunye nokucoca ibhodi yesekethe; Amanye amashishini abandakanya abathwali beegesi eziyingozi, izinyibilikisi zecrystallization yeziyobisi, izinto zokuncamathelisa, njl.
Ukupakishwa kunye noGcino
Ukupakisha: Ukupakishwa kunokwenziwa ngokwezifiso. ixesha lokuthumela lingaba ngolwandle, ngomoya, kunye nesampuli okanye inani elincinci lingathunyelwa nge-DHL, FEDEX, EMS kunye ne-TNT.
Ugcino: Gcina kwindawo epholileyo eyomileyo, kude nelanga elithe ngqo
Imiqathango yokugcina ngokukhuselekileyo, kuquka nakuphi na ukungahambelani
Yahlulwe kwizinto ezingahambelaniyo. Jonga iiNgozi zeMichiza. Gcina isikhongozeli sivalwe ngokuqinileyo kwindawo eyomileyo nengena umoya. Izikhongozeli ezivulwayo kufuneka ziphinde zivaliwe kwaye zigcinwe zime nkqo ukuthintela ukuvuza. Phatha kwaye ugcine phantsi kwegesi engasebenziyo.

Izilumkiso zokuphatha ngokukhuselekileyo
AKUKHO amadangatye avulekileyo, AKUKHO iintlantsi kwaye AKUKHO msi. AKUKHO ukunxibelelana neearhente oxidizing. Ngaphezu kwe-58°C sebenzisa isixokelelwano esivaliweyo kunye nokungena komoya. Ukuphatha kwindawo engena umoya. Nxiba iimpahla ezifanelekileyo zokuzikhusela. Kuphephe ukudibana nolusu namehlo. Kuphephe ukubunjwa kothuli kunye ne-aerosols. Sebenzisa izixhobo ezingatshisiyo. Thintela umlilo obangelwa ngumphunga wokukhupha i-electrostatic.
