Isho ukuthini inombolo ye-CAS? Ukuhlaziywa okuphelele “kwamakhadi omazisi” emboni yamakhemikhali
Embonini yamakhemikhali, sivame ukuhlangana negama elithi inombolo ye-CAS, okuyisihlonzi esiyinhloko ekucacisweni komkhiqizo, isizindalwazi samakhemikhali kanye nokusebenza kwansuku zonke. Kungakhathaliseki ukuthi ekucacisweni komkhiqizo, kusizindalwazi samakhemikhali, noma ekusebenzeni kwansuku zonke kwezinkampani zamakhemikhali, inombolo ye-CAS iyinkomba eyinhloko.Isho ukuthini inombolo ye-CAS? Lesi sihloko sizokunikeza impendulo enemininingwane.
Ithini inombolo ye-CAS?
Inombolo ye-CAS (Inombolo Yesevisi Yezifinyezo Zekhemikhali) iyinkomba eyingqayizivele enikezwe i-Chemical Abstracts Service (CAS). Ikhemikhali ngayinye, kungakhathaliseki ukuthi ivela ngokwemvelo noma yokwenziwa, inenombolo ye-CAS ehlukile, eyivumela ukuthi ikhonjwe ngokunembile futhi ilandelelwe emhlabeni wonke.
Isakhiwo nezici zenombolo ye-CAS
Inombolo ye-CAS ngokuvamile iqukethe izingxenye ezintathu zezinombolo, isibonelo 64-17-5, ezimele ulwazi oluhlukile:

Ingxenye yokuqala, engahluka kusuka kumadijithi amabili kuya kwayisikhombisa, ikhomba inombolo eyingqayizivele yento yamakhemikhali;
Ingxenye yesibili njalo iyinombolo enezinombolo ezimbili, esetshenziselwa ukulinganisa ingxenye yokuqala;
ingxenye yesithathu iyidijithi yokuhlola eyodwa, esetshenziselwa ukuqinisekisa ukunemba kwezingxenye ezimbili zokuqala zenombolo.

Lesi sakhiwo sivumela izinombolo ze-CAS ukuthi zigweme ukuphindaphinda futhi sinikeza indlela emisiwe yokuhlonza izinto zamakhemikhali.
Ukusetshenziswa Nokubaluleka Kwezinombolo Ze-CAS
Uma sesizwile ukuthi inombolo ye-CAS isho ukuthini, sidinga futhi ukuqonda ukuthi empeleni isetshenziselwa ini. inhloso enkulu yenombolo ye-CAS iwukuqinisekisa ukuthi ikhemikhali ihlukile futhi yaziwa emhlabeni jikelele. Njengoba izinto zamakhemikhali zingase zibe namagama neziteketiso eziningi, ukusetshenziswa kwenombolo ye-CAS kugwema ukudideka. Isibonelo, i-Ethanol ingase ibizwe ngokuthi utshwala, i-ethyl alcohol, njll. ezimweni ezihlukene, kodwa inombolo yabo ye-CAS 64-17-5 ihlukile, okuqinisekisa ukuthi akukho ukungaqondi kahle lapho kuxhunywa phakathi kwezilimi ezahlukene nezifunda.
Izinombolo ze-CAS zidlala indima ebalulekile ekuthengeni, ekukhangiseni, ekucwaningeni nasekulawuleni ukulawula embonini yamakhemikhali. Isibonelo, kokuthi AmaSpredishithi Edatha Yokuphepha (SDS), izinombolo ze-CAS zisetshenziselwa ukukhomba ngokucacile izinto zamakhemikhali ezihilelekile ukuze abathintekayo bazi kahle ukuthi yiziphi izici zento kanye nezingozi ezingaba khona.
Ukuthola kanye Nokubuza Izinombolo ze-CAS
Uma ufuna ukubheka inombolo ye-CAS yento yamakhemikhali, ungasesha kusizindalwazi samakhemikhali ambalwa aku-inthanethi, njengeRegistry ye-CAS, i-PubChem, nezinye. Lezi zingosi zolwazi zinikeza ingcebo yolwazi ngezinto zamakhemikhali, okuhlanganisa izinombolo zazo ze-CAS, izakhiwo zamangqamuzana, izakhiwo zamakhemikhali, nokunye.
Ezinkampanini, ukuba nezinombolo ezinembile ze-CAS akusizi nje kuphela ukuphatha ukuthobela imithetho, kodwa futhi kuthuthukisa ukusebenza kahle kokuphathwa kwe-supply chain. Isibonelo, ukuqinisekisa ukuthi izinto zokusetshenziswa ezithengwayo zifana ncamashi nezinto zamakhemikhali ezidingekayo ukuze kugwenywe izinkinga zekhwalithi noma izingozi zokulawula.
Isiphetho
Impendulo yombuzo wokuthi inombolo ye-CAS isho ukuthini idlulela ngale kwencazelo yayo yangempela endimeni yayo engenakushintshwa embonini yamakhemikhali, lapho isebenza 'njengekhadi likamazisi' lezinto zamakhemikhali, iqinisekisa ukuhlonza nokuphathwa kwazo okunembile emhlabeni wonke. Ukuqonda nokusebenzisa kahle izinombolo ze-CAS kuyikhono elibalulekile kulabo abasebenza embonini yamakhemikhali.
