Yini i-CAS?
I-CAS imele insizakalo yokuvalwa kwamakhemikhali, i-database egunyaziwe esethwe yi-American Chemical Society (ACS.) Inombolo ye-CAS, noma inombolo ye-CAS Registry, ikhompiyutha eyingqayizivele esetshenziselwa ukumaka izinto zamakhemikhali, ama-polymers, nokuningi . Embonini yamakhemikhali, inombolo ye-CAS iyithuluzi elibalulekile ngoba lisiza ososayensi kanye nonjiniyela kalula futhi bathole kabusha futhi babuyise izinto eziqondile zamakhemikhali.
Ukubaluleka kwenombolo ye-CAS
Embonini yamakhemikhali, ukukhonjwa nokulandelela kwezinto zamakhemikhali kungenye yezinto ezibalulekile zomsebenzi wansuku zonke. Njengoba izinto zamakhemikhali zingaba namagama amaningi, amagama ajwayelekile noma amagama omkhiqizo, lokhu kungaholela kalula ekudidekeni. Inombolo ye-CAS ixazulula le nkinga ngokunikeza inombolo endisiwe esetshenziswa emhlabeni jikelele. Akunandaba noma izinguquko egameni noma egameni lento yamakhemikhali, inombolo ye-CAS ihlala ifana ngokuhlukile entweni ethile. Le ndlela eqondile yokuhlonza ibalulekile ezindaweni eziningi kufaka phakathi ucwaningo kanye nentuthuko, ukutholwa, ukukhiqizwa kanye nokulandela umthetho wokulawula.
Ukwakheka kwenombolo ye-CAS nokubaluleka kwako
Inombolo ye-CAS imvamisa iqukethe izingxenye ezintathu: izinombolo ezimbili kanye nedijithi yokuhlola. Isibonelo, inombolo ye-CAS yamanzi ingu-7732-18-5- 25 isakhiwo, yize kubonakala sengathi silula, siphethe imininingwane eminingi. Amadijithi amathathu okuqala amelela isikhundla somuntu ku-Chemical Abstracts Service, isethi yesibili yamadijithi ikhombisa izakhiwo ezihlukile zento, futhi idijithi lokugcina lisetshenziselwa ukuqinisekisa ukuthi amadijithi edlule alungile. Ukuqonda ukwakheka kwezinombolo ze-CAS kusiza ochwepheshe ukuthi baqonde ngokushesha futhi bazisebenzise.
Cas embonini yamakhemikhali
Izinombolo ze-Cas zisetshenziswa kabanzi ekubhaliseni, ukulawulwa kanye nokuhweba kwemikhiqizo yamakhemikhali. Ngesikhathi sokubhalisa nokungeniswa kwemikhiqizo yamakhemikhali, izinombolo ze-CAS zivame ukufunwa yizinhlangano ezilawulayo ukuqinisekisa ukuphepha kanye nomthetho wamakhemikhali. Kuzohwebo lwamazwe omhlaba, izinombolo ze-CAS zisetshenziselwa futhi ukuqinisekisa ukuthi abathengi nabathengisi banolwazi olufanayo lomkhiqizo othengiswayo. Abaphenyi bamakhemikhali nabo badinga ukukhombisa izinombolo ze-CAS lapho beshicilela izincwadi noma ukufaka isicelo samalungelo obunikazi ukuqinisekisa ukunemba nokutholwa kokutholwa kwabo.
Ungazisebenzisa kanjani izinombolo ze-CA ukuthola imininingwane
Usebenzisa izinombolo ze-CAS, abasebenza embonini yamakhemikhali bangabuyisa ngokunembile ulwazi ngezinto zamakhemikhali kulwazi oluningi. Isibonelo, imininingwane ngeshidi ledatha yokuphepha kwezinto zamakhemikhali (SDS), ubuthi, umthelela wezemvelo, indlela yokukhiqiza kanye nentengo yemakethe konke konke kungatholakala ngokushesha kusetshenziswa inombolo ye-CAS. Lokhu kubuyisa okusebenzayo kokubuyisa kubaluleke kakhulu ezinkampanini zokwenza izinqumo ze-R & D kanye nokuhlola ubungozi.
Ukuqhathaniswa kwezinombolo ze-CA nezinye izinhlelo zokufaka izinombolo
Yize izinombolo ze-CAS zisetshenziswa kabanzi embonini yamakhemikhali, ezinye izinhlelo zokubala nazo zikhona, njengenombolo ye-UN yezizwe ezihlangene noma inombolo ye-EINECS ye-European Union. Uma kuqhathaniswa, izinombolo ze-CAS zinokumboza kabanzi kanye nokunemba okuphakeme. Lokhu kuholele ekubuseni kwezinombolo ze-CAS embonini yamakhemikhali emhlabeni wonke.
Ukugcina
Case, njengesikhombi esijwayelekile sezinto zamakhemikhali, sesiphenduke ithuluzi elisemqoka embonini yamakhemikhali. Ngokusebenzisa izinombolo ze-CAS, izinkampani zamakhemikhali kanye nabaphenyi bayakwazi ukuphatha futhi basebenzise imininingwane yezinto zamakhemikhali ngokunembe kakhudlwana nangendlela efanele, ngaleyo ndlela bathuthukise ukuthuthukiswa kwezentuthwane kanye nentuthuko yezobuchwepheshe. Ukuqonda futhi usebenzisa kahle inombolo ye-CAS akunakuthuthukisa ukusebenza kahle emsebenzini, kepha futhi kugwenywe ngempumelelo izingozi ezingaba khona.
