IDimethyl Formamide/DMF Umgangatho oZinzileyo kunye neXabiso lokuKhuphisana
Isicelo
I-Dimethyl formamide (i-DMF) njengesixhobo esibalulekileyo sekhemikhali ekrwada kunye ne-solvent egqwesileyo, isetyenziswa ikakhulu kwi-polyurethane, i-acrylic, i-pharmaceuticals, i-pesticides, idayi, i-electronics kunye namanye amashishini. Ihlanjwe kwishishini le-polyurethane njenge-arhente yokunyanga, isetyenziselwa ukuveliswa kwesikhumba esimanzi sokwenziwa; amachiza okwenziwa kwishishini lamachiza njengaphakathi, asetyenziswa ngokubanzi ekulungiseleleni i-doxycycline, i-cortisone, imveliso yeziyobisi ze-sulfa; ishishini acrylic ukucima ibhodi yesekethe njengesinyibilikisi ikakhulu esetyenziselwa imveliso acrylic owomileyo ukusonta; ishishini lokubulala izitshabalalisi ukuze kudityaniswe ukusebenza kakuhle okuphezulu kunye nezibulali-zinambuzane ezinetyhefu ephantsi; idayi kushishino lwedayi njengesinyibilikisi; iinxalenye zetoti kushishino lwe-elektroniki njengokucoca, njl.; amanye amashishini, kubandakanywa ophethe iigesi eziyingozi, i-crystallization yamachiza esebenzisa izinyibilikisi.

Ugcino
Njengoko i-Dimethyl Formamide (i-DMF) iyikhemikhali yendalo enokutsha kunye neendawo eziguqukayo, ezi ngongoma zilandelayo kufuneka ziqatshelwe ngexesha lokugcina:
1. Indawo yokugcina: I-DMF kufuneka igcinwe kwindawo epholileyo, eyomileyo kwaye engenamoya, ukuphepha ukukhanya kwelanga kunye nokushisa okuphezulu. Indawo yokugcina kufuneka ibe kude nomlilo, ubushushu kunye ne-oxidant, izixhobo ezikhusela ukuqhuma.
2. Ukupakishwa: I-DMFS kufuneka igcinwe kwizikhongozelo ezingangeni moya zomgangatho ozinzile, njengeebhotile zeglasi, iibhotile zeplastiki okanye iidrum zentsimbi. Ukuthembeka kunye nokuqina kwezikhongozeli kufuneka zihlolwe rhoqo.
3. Ukuthintela ukudideka: I-DMF ayifanele ixutywe ne-oxidant enamandla, i-asidi eqinile, isiseko esinamandla kunye nezinye izinto ukuphepha ukuphendula okuyingozi. Kwinkqubo yokugcina, ukulayishwa, ukukhulula kunye nokusetyenziswa, ingqalelo kufuneka ihlawulwe ukukhusela ukungqubana, ukungqubuzana kunye nokunyakaza, ukuphepha ukuvuza kunye neengozi.
4. Ukuthintela umbane omileyo: Kwi-DMF yokugcina, ukulayisha, ukukhupha kunye nokusetyenziswa kwenkqubo, kufuneka kuthintele ukuveliswa kombane omileyo. Amanyathelo afanelekileyo kufuneka athathwe, njengokubeka phantsi, ukugubungela, izixhobo ze-antistatic, njl.
5. Ukuchongwa kweleyibhile: Izikhongozeli zeDMF kufuneka ziphawulwe ngeeleyibhile ezicacileyo kunye nokuchongwa, ebonisa umhla wokugcinwa, igama, ugxininiso, ubuninzi kunye nolunye ulwazi, ukwenzela ukuba kube lula ukulawula kunye nokuchongwa.
