Ithini inombolo ye-CAS? -Ikhadi likamazisi lomhlaba wonke lezinto zamakhemikhali
"Inombolo ye-CAS" ingumqondo ovame kakhulu futhi obalulekile embonini yamakhemikhali, kungakhathaliseki ukuthi ungusokhemisi, umcwaningi noma uchwepheshe wokukhiqiza amakhemikhali. Kungakhathaliseki ukuthi ungusokhemisi, umcwaningi noma uchwepheshe osebenza embonini yamakhemikhali, kubalulekile ukuthi wazi futhi usebenzise inombolo ye-CAS.Ithini inombolo ye-CAS? Kungani ibaluleke kangaka? Kulesi sihloko, sizohlola le mibuzo ngokujulile.
1. Incazelo kanye nomsuka wenombolo ye-CAS
Inombolo ye-CAS, eyaziwa ngokuthi i-Chemical Abstracts Service Number, iyinombolo yokuhlonza eyingqayizivele eyabelwe into ngayinye yekhemikhali yi-Chemical Abstracts Service (CAS) e-US Inombolo ye-CAS ngokuvamile iqukethe amasethi amathathu ezinombolo ezihlukaniswa ngomugqa omfushane ovundlile, isb 123-45-6. Lolu hlelo lwezinombolo lwaqalwa ngo-1965 ukuze lunikeze indlela efanayo nemisiwe yokuhlonza izinto zamakhemikhali emhlabeni wonke. 2.
2. Isakhiwo kanye nencazelo yezinombolo ze-CAS
Isakhiwo senombolo ye-CAS silula futhi siqondile, kodwa sinencazelo ejulile ngemuva kwayo. Iqoqo ngalinye kwamathathu okuqala ezinombolo limelela ulwazi oluhlukene: isethi yokuqala yezinombolo ngokuvamile ibonisa ukulandelana lapho into ethile yamakhemikhali ibalwa esigabeni sayo; isethi yesibili yezinombolo isetshenziselwa ukuqhubeka nokuhlukanisa uhlobo lwento; futhi isethi yesithathu yezinombolo iyidijithi yesheke eqinisekisa ukunemba nokuhluka kwenombolo. Ngale nombolo, noma iyiphi into yamakhemikhali ingabonakala ngokunembile, kungakhathaliseki ukuthi inhlanganisela yezinto eziphilayo eziyinkimbinkimbi noma usawoti olula we-inorganic.
3. Ukusetshenziswa kwezinombolo ze-CAS embonini yamakhemikhali
Inombolo ye-CAS inezinhlobonhlobo zezicelo embonini yamakhemikhali. Isetshenziswa ekuthengeni nasekudayiseni amakhemikhali. Njengoba inombolo ye-CAS isetshenziswa emhlabeni wonke, yenza ukuhweba ngamakhemikhali kube lula kakhulu futhi igwema ukudideka okubangelwa umehluko wamagama amakhemikhali.Inombolo ye-CAS isetshenziswa futhi ocwaningweni nasekuthuthukisweni kwezinto zamakhemikhali, okuvumela abacwaningi ukuthi bathole imininingwane enemininingwane yento nemibhalo ehlobene, ngaleyo ndlela ithuthukise ukusebenza kahle kocwaningo.
4. Izici zomthetho nokuphepha zezinombolo ze-CAS
Ngaphezu kobubanzi bayo bezinhlelo zokusebenza, inombolo ye-CAS idlala indima ebalulekile ezicini zomthetho nezokuphepha. Eziqondisweni zamakhemikhali, amazwe amaningi nezifunda zidinga ukuthi abakhiqizi nabangenisa amakhemikhali banikeze izinombolo ze-CAS ukuze kuqinisekiswe ukuthotshelwa komkhiqizo, futhi izinombolo ze-CAS ziphinde zisetshenziswe kokuthi AmaSpredishithi Edatha Yokuphepha (SDS) ukuze amakhemikhali anikeze ulwazi olubalulekile lokuphepha kubasebenzi nakubathengi.
5. Kungani izinombolo ze-CAS zibalulekile ekulawuleni izinto zamakhemikhali
Ukuphathwa kwezinto zamakhemikhali kuye kwaba nzima nakakhulu ekukhiqizeni amakhemikhali esimanje. Njengoba ukuhwebelana kwembulunga yonke kushesha futhi namazinga okulawulwa kwezinto zamakhemikhali ehluka kuye ngamazwe kanye nesifunda ngesifunda, inombolo ye-CAS isebenza njengesihlonzi esifanayo ukuze isize izinkampani zamakhemikhali zisebenze ngokushelela ezindaweni ezihlukene zomthetho nezokulawula, futhi yenza kube lula ukulandela ngomkhondo nokuphathwa kohlu nokusetshenziswa kwento yamakhemikhali, inciphisa ubungozi obungaba khona bemvelo nokuphepha.
6. Ungazithola kanjani futhi uzisebenzise kanjani izinombolo ze-CAS
Izinombolo ze-CAS zivame ukutholwa ngokusesha isizindalwazi esifanele se-Chemical Abstracts Service (CAS). Kubalulekile ukuthi ochwepheshe bazi ukuthi bangazisebenzisa kanjani lezi zinsiza ngempumelelo. Empeleni, izinkampani zamakhemikhali zivame ukubhalisela isizindalwazi se-CAS ukuze zithole ulwazi lwakamuva lwezinto zamakhemikhali ngesikhathi sangempela. Izinhlangano eziningi zocwaningo namanyuvesi nazo zisebenzisa izinombolo ze-CAS ukwenza ucwaningo nokuqinisekisa ukunemba kwedatha nokungaguquguquki.
Isiphetho
Inombolo ye-CAS ibaluleke kakhulu embonini yamakhemikhali. Akugcini nje ngokuhlinzeka nge-ID eyamukelwa emhlabeni wonke yento yamakhemikhali, kodwa futhi idlala indima ebalulekile ekulawuleni amakhemikhali, ukuthobela umthetho, nokukhiqizwa okuphephile. Ngakho-ke, noma ngabe ungumakadebona embonini noma usafunda, ukuqonda okujulile kwenombolo ye-CAS kanye nokusetshenziswa kwayo kuzoba nomthelela omkhulu emsebenzini wakho.
