Ithini inombolo ye-CAS?

Inombolo ye-CAS (Chemical Abstracts Service Number) ukulandelana kwezinombolo okusetshenziselwa ukuhlonza ngokukhethekile into yamakhemikhali emkhakheni wamakhemikhali. kanye nokuhlukanisa izinto zamakhemikhali emhlabeni jikelele futhi isetshenziswa kakhulu emkhakheni wesayensi yamakhemikhali, eyekhemisi, neyezinto ezibonakalayo. amakhemikhali, imithi, isayensi yezinto kanye neminye imikhakha. Inombolo ye-CAS ikuvumela ukuthi uthole ngokushesha nangokunembile ulwazi oluyisisekelo, ifomula yesakhiwo, izakhiwo zamakhemikhali kanye neminye imininingwane ehlobene yento yamakhemikhali.

Kungani ngidinga ukucinga inombolo ye-CAS?

Ukusesha inombolo ye-CAS kunezinjongo eziningi kanye nokusetshenziswa. Kungasiza ososayensi, abacwaningi kanye nabasebenzi bemboni ukuhlonza ngokushesha ulwazi oluthile mayelana nekhemikhali. Ukwazi inombolo ye-CAS yekhemikhali kubalulekile lapho kukhiqizwa, kwenziwa ukucwaninga noma ukumaketha ikhemikhali, futhi ukubhekwa kwenombolo ye-CAS kungasiza ukugwema ukusetshenziswa kabi noma ukudideka njengoba amanye amakhemikhali angase abe namagama afanayo noma izifinyezo kuyilapho inombolo ye-CAS ihlukile.Izinombolo ze-CAS nazo zibanzi kakhulu. esetshenziswa ekuhwebeni kwamakhemikhali kwamanye amazwe nasekulawuleni izinto ukuze kuqinisekiswe ukuthi ulwazi olumayelana nekhemikhali ludluliselwa emhlabeni wonke ngendlela enembile.

Ngilwenza kanjani usesho lwenombolo ye-CAS?

Kunezindlela ezimbalwa namathuluzi okwenza usesho lwenombolo ye-CAS. Enye indlela evamile iwukusesha kuwebhusayithi ye-Chemical Abstracts Service (CAS), okuyisizindalwazi esisemthethweni sezinombolo ze-CAS futhi ehlinzeka ngolwazi olubanzi ngezinto zamakhemikhali. Kukhona nenani lamawebhusayithi ezinkampani zangaphandle kanye namathuluzi ahlinzeka ngokubheka izinombolo ze-CAS, ngokuvamile ahlanganisa ulwazi olwengeziwe mayelana nohlelo lwamakhemikhali, i-MSDS (Amashidi Wedatha Yokuphepha Okubalulekile), kanye nezixhumanisi zeminye imithetho. Izinkampani noma izinhlangano zocwaningo zingasebenzisa futhi imininingwane yangaphakathi ukuze zilawule futhi zibuze izinombolo ze-CAS ngezidingo zazo ezithile.

Ukubaluleka Kokubheka Inombolo Ye-CAS Embonini

Embonini yamakhemikhali, ukubheka inombolo ye-CAS kuwumsebenzi obalulekile futhi obalulekile. Akusizi nje kuphela izinkampani ukuthi ziqinisekise ukuthi amakhemikhali eziwasebenzisayo ahambisana nezindinganiso nemithetho yamazwe ngamazwe, futhi kunciphisa ubungozi. Isibonelo, lapho kuthengwa amazwe ngamazwe, izinombolo ze-CAS ziqinisekisa ukuthi amakhemikhali ahlinzekwe umphakeli afana ncamashi nalawo adingwa uhlangothi lwesidingo.Ukuhlolwa kwezinombolo ze-CAS nakho kudlala indima ebalulekile ekuthuthukisweni kwamakhemikhali amasha, ukuhlolwa kokuthotshelwa kwemikhiqizo, kanye nemvelo. ukuphathwa kwezempilo nokuphepha.

Izinselelo Nokucatshangelwa Kokubheka Inombolo Ye-CAS

Nakuba amathuluzi okubheka izinombolo ze-CAS etholakala kabanzi, ezinye izinselelo zisekhona. Amanye amakhemikhali angase angabi nayo inombolo ye-CAS anikezwe wona, ikakhulukazi izinto ezisanda kuthuthukiswa noma eziyinhlanganisela, futhi ukubhekwa kwenombolo ye-CAS kungase kuveze ulwazi olungahambisani kuye ngomthombo wedatha. Ngakho-ke, kubalulekile ukukhetha umthombo wedatha othembekile lapho wenza umbuzo. Ezinye izingosi zolwazi zingadinga ukubhalisa okukhokhelwayo, ngakho abasebenzisi badinga ukukala inani ledatha ngezindleko zokufinyelela.

Isiphetho

Ukubheka izinombolo ze-CAS kuyithuluzi elibalulekile embonini yamakhemikhali, okusiza zonke izinhlangothi ukuqinisekisa ukuphepha kwamakhemikhali nokuhambisana. Ukuqonda ukuthi kwenziwa kanjani ngempumelelo ukubheka izinombolo ze-CAS, kanye nokuqonda ukusetshenziswa kwazo nezinselele embonini, kuzoba usizo olubalulekile kochwepheshe bamakhemikhali kanye nodokotela abahlobene. Ngokusebenzisa imithombo yedatha enembile negunyaziwe yokubheka izinombolo ze-CAS, ukusebenza kahle nokuthembeka kwedatha kungathuthukiswa ngempumelelo.
