Ingozi yokuphefumula:Ukungcoliswa komoya okulimazayo ngeke noma kuzofinyelelwa kancane kancane ukuhwamuka kwale nto ngo-20 ° C; Lapho ngifafaza noma ukusabalalisa, noma kunjalo, ngokushesha okukhulu.
Imiphumela yokuvezwa kwesikhathi esifushane:Into icasulayo emehlweni naseqenjini lokuphefumula. Into icasula kancane esikhunjeni. Ukuvezwa kokugxila okuphezulu kakhulu kungadala ukwehlisa ukwazi.
Imiphumela yokuvezwa kwesikhathi eside:Ukuxhumana okuphindaphindwayo noma okuhlala isikhathi eside nesikhumba kungadala i-dermatitis. Ukuhlolwa kwezilwane kukhombisa ukuthi le nto kungenzeka ibangele imiphumela enobuthi emikhiqizweni yomuntu.
Isingeniso Esinemininingwane
N-methyl-2-pyrlorone (NMP)Ingabe uketshezi olucacile, olungenamibala ngephunga elimnandi kancane. Kuyinto ehlanganisiwe ye-organic ngefomula yamakhemikhali c5h9no. I-NMP ayikuzinzile ngamanzi futhi i-organic solvents eningi, okwenza kube yi-solvent eguquguqukayo emidlalweni ehlukahlukene.
I-NMP inephupho eliphakeme elibi kakhulu eliseduze kuka-202-204 ° C (396-399 ° F) kanye nengcindezi ephansi ye-vapor, okwenza kube lusizo ezinhlelweni ezidinga ukuqina okushisa kakhulu. Inokubonakala okuphansi okuphansi namandla amahle we-solvency, okwenza ukuthi kuncibilike ukwahluka kwezinto zokwakha kufaka phakathi ama-polymers, ama-resins, nezinye izinhlanganisela eziphilayo.
I-NMP i-polar kakhulu, okwenza kube yi-solvent enhle kakhulu yezinto ze-polar. Inomzuzu we-Dipole we-3.78 debye, okuvumela ukuthi ixazululwe futhi ibambe izinkunzo ezikhokhiswayo. Le mpahla yenza i-NMP ilungele ukusetshenziswa ekuphendukeni okuningi kwamakhemikhali, ngoba ingakwazi ukwenza lula ukuchitheka kanye namazinga okuphendula.
Kubalulekile ukuqaphela ukuthi i-NMP inokucatshangelwa okuthile kwezempilo nokuphepha. Kungadonswa ngesikhumba futhi ukuphefumula kwama-vapors alo kungadala ukucasuka ohlelweni lokuphefumula. Ukuchayeka isikhathi eside noma okuphindaphindwayo ku-NMP kungaba nemiphumela emibi ekuqinisekeni nasekuthuthukisweni kwengane kwabesifazane abakhulelwe. Ngenxa yalokho, kufanele kulandelwe izinyathelo zokuphepha ezifanele kanye nemihlahlandlela lapho kuphathwa futhi kusetshenziswa i-NMP.
Isicelo
I-N-methyl-2-pyrlolidone (NMP) iyi-solvent esetshenziswa kakhulu kwizimboni ezahlukahlukene. Nazi ezinye izinhlelo zokusebenza ze-NMP:
Izemithi: I-NMPP isetshenziswa njenge-solvent emkhakheni wezemithi ekwakhiweni kwemikhiqizo yezidakamizwa. Ingancibilikisa izithako ezahlukahlukene zemithi ezisebenzayo (APIS) kanye ne-Excipients, okwenza kube lula ukwenza izinqubo zokwakhiwa kwezidakamizwa ezinjengokudilizwa kwezidakamizwa, ukuthuthukiswa kwezidakamizwa, kanye nezinhlelo zokulethwa kwezidakamizwa.
Ukuhlanza Kwezimboni: I-NMP i-solvent esebenza kahle kakhulu yokususa izinhlobo ezahlukahlukene zokungcola, ezinjengamafutha, ama-grees, kanye nama-resins. Isetshenziswa kakhulu kwizicelo zokuhlanza izimboni, kufaka phakathi ukucwilisa nokuhlanza izikhala zensimbi, imishini, kanye nezinto ze-elekthronikhi.
Amapende nezimbobo: I-NMPP isetshenziswa njenge-solvent ekwakhekeni kwamapende, izimbobo, kanye nama-varnish. Kuyasiza ukuncibilikisa ama-resin nezinye izinto, kuthuthukisa izindawo zokugeleza kanye nezindawo zokulinganisa zokuhlanganiswa, futhi kuthuthukisa ukunamathela ku-substrate.
Ukucutshungulwa kwe-polymer:I-NMPP isetshenziswa ekusebenzeni kwe-polymer njenge-solvent yama-polymers ahlukahlukene, kufaka phakathi i-polyvinylidene fluoride (PVDF), i-polyurethane (pu), ne-polyvinyl chloride (PVC). Isetshenziswa ezinqubweni ezinjengokujikeleza, ukuphonsa kanye nokwakheka kwefilimu.
I-Electronics: I-NMPP isetshenziswa embonini ye-elekthronikhi yokuhlanza nokuhlanza ama-elekthronikhi, njenge-semiconductors, amabhodi wesifunda, nezixhumi. Kungasusa ngempumelelo izinsalela ze-flux, ama-pastes wokuthengisa, nezinye izinto ezingcolile ngaphandle kokulimaza izingxenye zobuntu bama-elekthronikhi.
Ama-Agrochemicals:I-NMPP isetshenziswa njenge-solvent ekwakhekeni kwama-agrochemicals, kufaka phakathi ama-herbicides, ama-insecticides kanye nama-fungicides. Kuyasiza ekuqedeni izithako ezisebenzayo nezinye izinto, ukuqinisekisa ukusakazeka okufanele nokusetshenziswa okusebenzayo kwama-agrochemicals.
Amabhethri e-Lithium-ion:I-NMPP isetshenziswa njenge-solvent yokulungiselela i-electrode kanye nokwenziwa kwama-electrolyte kumabhethri e-lithium-ion. Kuyasiza ukuncibilikisa futhi ziqinise usawoti we-lithium nezinye izinto ze-electrolyte, kuqinisekisa ukusebenza kwebhethri.
Kubalulekile ukuqaphela ukuthi i-NMP kufanele isetshenziswe ngokuqapha kanye nezindlela zokuphepha ezifanele ngenxa yezingozi zayo zezempilo nezemvelo. Kungcono ukulandela imihlahlandlela ethile nemithethonqubo ebekwe yiziphathimandla zasendaweni kanye namazinga embonini lapho usebenzisa i-NMP.
