Yintoni inombolo yeCAS? -Ikhadi lesazisi sehlabathi lezinto zekhemikhali
"Inombolo ye-CAS" yinto eqhelekileyo kwaye ibaluleke kakhulu kwishishini lemichiza, nokuba ungumkhemikhali, umphandi okanye uchwephesha wokuvelisa imichiza. Nokuba ungusokhemisti, umphandi okanye uchwephesha osebenza kwishishini lemichiza, kubalulekile ukuba uyazi kwaye usebenzise inombolo ye-CAS.Ithini inombolo ye-CAS? Kutheni ibalulekile nje? Kweli nqaku, siza kuyihlolisisa nzulu le mibuzo.
1. Inkcazo kunye nemvelaphi yenombolo ye-CAS
Inombolo ye-CAS, eyaziwa ngokuba yiNombolo yeNkonzo yeMichiza yeeNgcaciso zeMichiza, yinombolo yokuchonga eyodwa enikwe into nganye yekhemikhali yiNkonzo yeMichiza ye-Abstracts (CAS) e-US Inombolo ye-CAS idla ngokuba neeseti ezintathu zamanani ezahlulwe ngomgca othe tye omfutshane, umz. 123-45-6. Le nkqubo yamanani yaqalwa ngo-1965 ukuze ibonelele ngendlela efanayo nesemgangathweni yokuchonga imichiza kwizinga lehlabathi. 2.
2. Ubume kunye nentsingiselo yamanani e-CAS
Ubume benombolo ye-CAS ilula kwaye ithe ngqo, kodwa inentsingiselo enzulu emva kwayo. Nganye kwiiseti ezintathu zokuqala zamanani imele ulwazi olwahlukileyo: iseti yokuqala yamanani idla ngokubonisa ukulandelelana kwayo imichiza ethile ibekwe kudidi lwayo; iseti yesibini yamanani isetyenziselwa ukwahlula kwakhona uhlobo lwento; kwaye iseti yesithathu yamanani yidijithi yokutshekisha eqinisekisa ukuchaneka kunye nokukodwa kwenani. Ngeli nani, nayiphi na into yeekhemikhali inokuchongwa ngokuchanekileyo, nokuba i-compound organic compound okanye ityuwa elula ye-inorganic.
3. Ukusetyenziswa kwamanani e-CAS kwishishini lemichiza
Inombolo ye-CAS inoluhlu olubanzi lwezicelo kwishishini lemichiza. Isetyenziselwa ukuthengwa nokuthengiswa kweekhemikhali. Njengoko inombolo ye-CAS isetyenziswe kwihlabathi jikelele, yenza ukuba urhwebo lweekhemikhali lube lula ngakumbi kwaye lugweme ukudideka okubangelwa ukuhlukana kwamagama ekhemikhali.Inombolo yeCAS iphinda isetyenziswe kuphando kunye nophuhliso lwezinto zekhemikhali, ezivumela abaphandi ukuba bafumane ulwazi olucacileyo lwento kunye neencwadi ezinxulumene nazo, ngaloo ndlela kuphuculwe ukusebenza kakuhle kophando.
4. Imiba yomthetho nokhuseleko lwamanani e-CAS
Ukongeza kuluhlu lwayo olubanzi lwezicelo, inombolo ye-CAS nayo idlala indima ebalulekileyo kwimiba yomthetho kunye nokhuseleko. Kwimimiselo yeekhemikhali, amazwe amaninzi kunye nemimandla ifuna ukuba abavelisi kunye nabathumeli beekhemikhali banikeze iinombolo ze-CAS ukuqinisekisa ukuthotyelwa kwemveliso, kwaye iinombolo ze-CAS zikwasetyenziswa kwi-Safety Data Sheets (SDS) kwiikhemikhali ukubonelela ngolwazi olubalulekileyo lokhuseleko kubasebenzi kunye nabathengi.
5. Kutheni amanani e-CAS ebaluleke kakhulu kulawulo lwemichiza
Ukulawulwa kwezinto zeekhemikhali kuye kwaba nzima ngakumbi kwimveliso yanamhlanje yemichiza. Njengoko umanyano lwamazwe ngamazwe lukhawulezisa kunye nemigangatho yolawulo lwemichiza yohluka ukusuka kwilizwe ukuya kwilizwe kunye nommandla ukuya kummandla, inombolo ye-CAS isebenza njengesichongi esifanayo sokunceda iinkampani zeekhemikhali zisebenze kakuhle kwiindawo ezahlukeneyo zomthetho kunye nolawulo, kwaye iququzelela ukulandelwa kunye nokulawulwa koluhlu lwezixhobo zekhemikhali kunye nokusetyenziswa, ukunciphisa umngcipheko onokubakho wokusingqongileyo kunye nokhuseleko.
6. Indlela yokufumana nokusetyenziswa kweenombolo zeCAS
Amanani e-CAS adla ngokufunyanwa ngokukhangela i-database efanelekileyo ye-Chemical Abstracts Service (CAS). Kubalulekile ukuba iingcali zazi indlela yokusebenzisa ezi zixhobo ngokufanelekileyo. Enyanisweni, iinkampani zeekhemikhali zihlala zibhalisela kwiinkcukacha ze-CAS ukuze zifumane ulwazi oluhlaziyiweyo kwizinto zekhemikhali ngexesha langempela. Imibutho emininzi yophando kunye neeyunivesithi nazo zisebenzisa amanani e-CAS ukwenza uphando kunye nokuqinisekisa ukuchaneka kwedatha kunye nokuhambelana.
Ukuqukumbela
Inombolo ye-CAS ibaluleke kakhulu kwishishini lemichiza. Akukona nje ukubonelela nge-ID eyamkelekileyo emhlabeni jikelele kwi-chemical substance, kodwa iphinda idlale indima ebalulekileyo ekulawuleni imichiza, ukuthotyelwa komthetho, kunye nokuveliswa okukhuselekileyo. Ke ngoko, nokuba ungumlindi kwishishini okanye ungumfundi oqalayo, ukuqonda okunzulu kwenombolo ye-CAS kunye nokusetyenziswa kwayo kuya kuba nefuthe elibi emsebenzini wakho.
