Ithini inombolo ye-CAS?

Inombolo ye-CAS (Chemical Abstracts Service Number) ukulandelana kwezinombolo okusetshenziselwa ukuhlonza ngokukhethekile into yamakhemikhali emkhakheni wekhemistri.Inombolo ye-CAS iqukethe izingxenye ezintathu ezihlukaniswe i-hyphen, isb. 58-08-2.Iwuhlelo olujwayelekile lokuhlonza nokuhlukanisa izinto zamakhemikhali emhlabeni wonke futhi livame ukusetshenziswa emkhakheni wamakhemikhali, wesayensi nesayensi. 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 ekugwemeni ukusetshenziswa kabi noma ukudideka njengoba amanye amakhemikhali angase abe namagama afanayo noma izifinyezo kuyilapho inombolo ye-CAS ihlukile.

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, ukucwaningwa kokuthotshelwa kwemikhiqizo, kanye nokuphathwa kwezempilo nokuphepha kwemvelo.

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 ukubheka izinombolo ze-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.
