Isho ukuthini inombolo ye-CAS? -Ukuqonda "ikhadi likamazisi" lekhemikhali
Isho ukuthini inombolo ye-CAS? Embonini yamakhemikhali, Inombolo ye-CAS iyinkomba yekhemikhali ebalulekile ehlonza ngokukhethekile ikhemikhali ngayinye, futhi inikezwa i-Chemical Abstracts Service (CAS) futhi ibaluleke njengekhadi likamazisi womuntu. Ngokuqonda incazelo, ukwakheka kanye nenjongo yenombolo ye-CAS, singayiqonda kangcono indima yayo ebalulekile ocwaningweni lwamakhemikhali, ukukhiqizwa kanye nohwebo.
Ithini inombolo ye-CAS?
Inombolo ye-CAS, eyaziwa ngokuthi Inombolo Yokubhaliswa Kwesevisi Yezifinyezo Zekhemikhali, iyinkomba eyingqayizivele ehlanganisa inombolo nodeshi okhomba into ngayinye yamakhemikhali eyaziwayo. inombolo ye-CAS ngokuvamile iqukethe inombolo enezingxenye ezintathu ngefomethi “XXX-XX-X”. Isibonelo, inombolo ye-CAS yamanzi ngu-7732-18-5. ingxenye yokuqala ngokuvamile iyinani eliphelele lamadijithi afinyelela kwangu-7, ingxenye yesibili inombolo enamadijithi angu-2, kanti ingxenye yesithathu iyidijithi yesheke enedijithi engu-1. Lesi sakhiwo senza inombolo ngayinye ye-CAS ihluke, iqinisekisa ukunemba nokungaguquguquki ekuhlonzweni kwezinto zamakhemikhali embonini yamakhemikhali yomhlaba wonke.
Iyini inhloso yenombolo ye-CAS?
Ngemuva kokuqonda ukuthi inombolo ye-CAS isho ukuthini, sidinga futhi ukwazi ukusetshenziswa kwayo okuyinhloko. Embonini yamakhemikhali namakhemikhali, izinombolo ze-CAS zisetshenziswa kabanzi ngalezi zindlela ezilandelayo:
Ukuhlonzwa kwezidakamizwa nokubuyiswa kolwazi: Njengoba amagama ezinto zamakhemikhali engase ahluke ngolimi ngolimi noma isifunda ngesifunda, inombolo ye-CAS, njengesihlonzi esiyingqayizivele, igwema ngempumelelo ukudideka okubangelwa yilokhu kungahambisani. Ososayensi, abacwaningi kanye namabhizinisi basebenzisa izinombolo ze-CAS ukuze bathole ngokushesha futhi ngokunembile ulwazi oluningiliziwe mayelana nekhemikhali, okuhlanganisa isakhiwo samangqamuzana, izakhiwo ze-physicochemical, izindawo zokufaka isicelo nokunye.

Ukulawulwa kokuthobelana nokuphepha: Emhlabeni wonke, izinombolo ze-CAS zidingeka ngokwemithetho yokulawulwa kwamakhemikhali emazweni nasezifundeni eziningi. Isibonelo, inombolo ye-CAS iwulwazi oludingekayo kumashidi edatha yokuphepha kwamakhemikhali (SDS). Isiza izinkampani nabalawuli ukuthi baphathe kangcono ukugcinwa, ukuthuthwa kanye nokusetshenziswa kwamakhemikhali ukuze kuqinisekiswe ukuthotshelwa kwemithetho efanele kanye namazinga okuphepha.

I-International Trade and Supply Chain Management: Ekuhwebeni kwamazwe ngamazwe kanye nokuthuthwa kwemikhiqizo yamakhemikhali, inombolo ye-CAS isebenza njengolimi oluvamile, isusa ukungaqondakali namaphutha avela ngenxa yokwehluka kwamagama ezinto zamakhemikhali kanye nokukhuthaza ukubonakala nokusebenza kahle ochungechungeni lokuhlinzeka.

Ungazithola kanjani futhi uzisebenzise kanjani izinombolo ze-CAS?
Ngemva kokuqonda ukuthi inombolo ye-CAS isho ukuthini nokubaluleka kwayo, sidinga futhi ukwazi ukuthi singayithola kanjani futhi sisebenzise inombolo ye-CAS. Kunezindlela ezimbalwa zokuthola inombolo ye-CAS:
Izincwadi zamakhemikhali nezizindalwazi: Izinombolo ze-CAS ekuqaleni zavela kusizindalwazi se-Chemical Abstracts Service. Namuhla, imininingwane eminingi eku-inthanethi, njenge-PubChem, i-ChemSpider, ne-SciFinder, inikeza ukufinyelela kuzinombolo ze-CAS kanye nolwazi lwazo lwamakhemikhali ahlobene.

Abahlinzeki bamakhemikhali nabakhiqizi: Abahlinzeki bamakhemikhali abaningi babonisa izinombolo ze-CAS ezincazelweni zemikhiqizo yabo namalebula ukuze basize amakhasimende akhombe futhi athenge ikhemikhali efanele.

Isihluthulelo sokusebenzisa izinombolo ze-CAS ukuthi zihlukile futhi ziqashelwa kabanzi. Kungakhathaliseki ukuthi umcwaningi usesha izincwadi zamakhemikhali noma inkampani iqinisekisa ukuthi imikhiqizo yayo ithobela izindinganiso zamazwe ngamazwe, inombolo ye-CAS iyithuluzi elilula nelithembekile.
Kungani izinombolo ze-CAS zibaluleke kangaka?
Inombolo ye-CAS ingaphezu nje kwenombolo, imele ulimi oluvamile lomhlaba wamakhemikhali. Ukwazi ukuthi inombolo ye-CAS isho ukuthini kusiza ukuqonda indima yayo eyinhloko ekuhlonzeni amakhemikhali, ukuthobela imithetho, ukuphathwa kokuphepha kanye nohwebo lwamazwe ngamazwe. Emhlabeni wanamuhla wembulunga yonke, inombolo ye-CAS isebenza 'njengekhadi likamazisi' lamakhemikhali, eliqinisekisa ukufana nokuba sobala ekuphathweni kwamakhemikhali emazweni nasezifundeni.
Isiphetho
Iyini incazelo yenombolo ye-CAS akuwona nje umbuzo wochwepheshe bamakhemikhali, kodwa futhi iphuzu lolwazi olunethonya elibanzi. Kungakhathaliseki ukuthi usocwaningweni, ekukhiqizweni, noma kwezohwebo, ukusetshenziswa kwezinombolo ze-CAS kusiza ukunciphisa ukungaqondi kahle, ukuthuthukisa ukusebenza kahle, nokuqinisekisa ukuphepha. Ngakho-ke, ukujwayela imiqondo nokusetshenziswa kwezinombolo ze-CAS kubalulekile kulabo abasebenza kumakhemikhali noma izimboni ezihlobene.
