Intengo enhle nekhwalithi ephezulu ye-isopropyl alcohol 99.9%
Ukuchazwa Komkhiqizo
I-Isopropyl Alcohol (IPA), eyaziwa nangokuthi i-2-propactol noma ukuhlikihla utshwala, iwuketshezi olungenamibala, oluvuthayo ngephunga elinamandla. Kuyinto evamile, i-ejenti yokuhlanza, kanye nokuhlanza, futhi isetshenziswa kabanzi embonini, ukunakekelwa kwempilo kanye nasezilungiselelweni zasendlini.
Umsebenzi
Ingasetshenziswa njenge-nitrocellulose, irabha, ukunamathela, i-Shellac, i-alkalo, enjenge-solvent, i-aerosol, ukukhiqizwa kwe-antifoggant ye-pigment, i-antifoggant ebonakalayo njll., esetshenziswe njenge-dilouse yokunamathela, futhi esetshenziselwa i-antifreeze, i-ejenti yokuphelelwa ngamandla, njll. Embonini kagesi, ingasetshenziswa njenge-ejenti yokuhlanza. Imboni yamafutha, i-ejenti yokukhishwa kwamafutha e-cottonseed, nayo ingasetshenziselwa ulwelwesi lwezilwane zezilwane ezihlekisayo.
Isitoreji Nezenzelana
I-Sopropyl Alcohol ikhiqizwa yi-hydration ye-Purpation noma nge-hydrogenation ye-acetone. Kuyinto solvent eguquguqukayo engancibilikisa izinto eziningi, kufaka phakathi amafutha, ama-resin kanye nezinsini. Futhi kuyisibulala-magciwane futhi kusetshenziselwa ukuhlanza nokufaka abize imishini yezokwelapha kanye nokuqina.
Naphezu kokusetshenziswa kwayo okuningi, i-soplopylyl yotshwala ingaba yingozi uma ingaphathwa kahle. Kungaba ubuthi uma kungeniswe noma kufakwe ngaphakathi ngobuningi, futhi kungadala ukucasuka kwesikhumba nokucasuka kwamehlo. Kuyavutha futhi kufanele kugcinwe endaweni epholile, eyomile, enomoya omuhle kude nemithombo yokushisa, izinhlansi, noma amalangabi.
Ukugcina ngokuphepha utshwala be-isopropyl, kufanele kugcinwe esitsheni esivaliwe ngokuqinile, kude nokukhanya kwelanga okuqondile nemithombo yokushisa. Akufanele igcinwe eduze kwama-oxidizing agents noma ama-acid, ngoba kungaphendula ngalezi zinto ukukhiqiza ama-byproducts ayingozi.
Ngamafuphi, i-sopropyl Alcohol ngamakhemikhali ahlukahlukene anezimboni eziningi, ukunakekelwa kwempilo kanye nezicelo zasendlini. Kodwa-ke, kungaba yingozi uma ingagcinwa futhi igcinwe kahle, futhi kufanele isetshenziswe ngokuqapha ukugwema ukulimala noma ukulimala.
