Umgangatho ozinzileyo weDimethyl Formamide/DMF kunye nexabiso elikhuphisanayo
Isicelo
I-Dimethyl formamide (DMF) njengezinto ezibalulekileyo zekhemikhali kunye nesinyibilikisi esibalaseleyo, esisetyenziswa kakhulu kwi-polyurethane, i-acrylic, amayeza, izibulali-zinambuzane, iidayi, izixhobo ze-elektroniki kunye nezinye izimboni. Ihlanjwe kwishishini le-polyurethane njengearhente yokuphilisa, isetyenziselwa kakhulu ukuvelisa ulusu olumanzi oluyilwe; iziyobisi zokwenziwa kwishishini lamayeza njengezinto eziphakathi, ezisetyenziswa kakhulu ekulungiseleleni i-doxycycline, i-cortisone, imveliso yamayeza e-sulfa; ishishini le-acrylic ibhodi yesekethe yokucima njengesinyibilikisi esetyenziselwa kakhulu ukuvelisa i-acrylic dry spinning; ishishini lezinambuzane zokwenziwa kwezibulali-zinambuzane ezisebenzayo eziphezulu kunye nezinobuthi obuphantsi; idayi kwishishini ledayi njengesinyibilikisi; iindawo ezifakwe kwiitini kwishishini le-elektroniki njengokucoca, njl.njl.; amanye amashishini, kubandakanya nomphathi weegesi eziyingozi, i-crystallization yamayeza esebenzisa izinyibilikisi.

Indawo yokugcina izinto
Njengoko iDimethyl Formamide (DMF) iyikhemikhali yendalo eneempawu ezitshayo nezitshintshatshintshayo, la manqaku alandelayo kufuneka aqatshelwe ngexesha lokugcina:
1. Indawo yokugcina: I-DMF mayigcinwe kwindawo epholileyo, eyomileyo nengena umoya kakuhle, kuthintelwe ukukhanya kwelanga ngqo kunye nobushushu obuphezulu. Indawo yokugcina mayibe kude nomlilo, ubushushu kunye nezixhobo ezikhusela ukuqhuma.
2. Ukupakisha: I-DMFS kufuneka igcinwe kwizikhongozeli ezingangeni moya ezisemgangathweni ozinzileyo, ezifana neebhotile zeglasi, iibhotile zeplastiki okanye iidrama zesinyithi. Ukuqina kunye nokuqina kwezikhongozeli kufuneka kuhlolwe rhoqo.
3. Thintela ukudideka: I-DMF akufuneki ixutywe ne-oxidant enamandla, i-asidi enamandla, isiseko esinamandla kunye nezinye izinto ukuze kuthintelwe iimpembelelo eziyingozi. Kwinkqubo yokugcina, yokulayisha, yokukhupha nokusebenzisa, kufuneka kunikwe ingqalelo ukuthintela ukungqubana, ukungqubana kunye nokungcangcazela, ukuze kuthintelwe ukuvuza kunye neengozi.
4. Ukuthintela umbane ongashukumiyo: Kwinkqubo yokugcina, ukulayisha, ukukhupha nokusebenzisa i-DMF, kufuneka kuthintelwe ukuveliswa kombane ongashukumiyo. Amanyathelo afanelekileyo kufuneka athathwe, anjengokumisa umhlaba, ukugquma, izixhobo ezichasene nombane ongashukumiyo, njl.njl.
5. Ukuchonga iileyibhile: Izikhongozeli ze-DMF maziphawulwe ngeeleyibhile ezicacileyo kunye nokuchonga, okubonisa umhla wokugcina, igama, uxinano, ubungakanani kunye nolunye ulwazi, ukuze kube lula ukulawula kunye nokuchonga.
