YINTONI?
I-CASS imele inkonzo ye-affilicals yekhemikhali, indawo yedatha egunyazisiweyo yase-Melika (i-ACS.) Inombolo ye-CAS, okanye inombolo yerejista ye-CASS, i-collters, ulandelelwano lwebhayiloji, kunye nangaphezulu . Kumzi-mveliso wekhemikhali, inombolo ye-CAS sisixhobo esibalulekileyo kuba inceda izazinzulu neenjineli kwaye zichonge ngokuchanekileyo kwaye zibuyise izinto ezithile zekhemikhali.
Ukubaluleka kwenombolo ye-CAS
Kumzi-mveliso wekhemikhali, isazisi kunye nokulandelwa kwezinto zekhemikhali yenye yezinto eziphambili zomsebenzi. Njengoko izinto zekhemikhali zinokuba namagama amaninzi, amagama aqhelekileyo okanye amagama oqalayo, oku kunokukhokelela ekudidekeni. Inombolo ye-CAS isombulula le ngxaki ngokubonelela ngenani eliqhelekileyo elisetyenziswa kwihlabathi liphela. Nokuba zithini na iinguqu egameni okanye ulwimi lwezinto zemichiza, inombolo ye-CAS ihambelana ngokukhethekileyo kwinto ethile. Le ndlela ichanekileyo yokuchonga ibalulekile kwiindawo ezininzi kubandakanya nophando kunye nophuhliso, ukuthengwa, ukuvelisa kunye nokuthotyelwa komgaqo.
Ubume benombolo ye-CAS kunye nokubaluleka kwayo
Inombolo ye-CAS ihlala inamacandelo amathathu: amanani amabini kunye nenombolo yokutshekisha. Umzekelo, inombolo ye-CAS yamanzi yi-7732-18-5.Isakhiwo, nangona ibonakala ilula, inomtsalane. Iinombolo ezintathu zokuqala zibonisa isikhundla sezinto kwinkonzo ye-Affic Sport, iseti yesibini yamanani ibonisa iipropathi ezizodwa, kunye nenombolo yokugqibela yokutshekisha isetyenziselwa ukuqinisekisa ukuba amanani angaphambili achanekile. Ukuqonda ubume be-CAS kunceda abasebenzi ukuze baziqonde ngokukhawuleza kwaye bazisebenzise.
I-CASS kwiShishini lekhemikhali
Iinombolo ze-CAS zisetyenziswa ngokubanzi kubhaliso, kwimigaqo kunye norhwebo lweemveliso zekhemikhali. Ngexesha lobhaliso kunye nokungenisa iimveliso zekhemikhali, iinombolo ze-CAS zihlala zifunwa ziiarhente zolawulo ukuqinisekisa ukhuseleko kunye nendalo yeekhemikhali. Kurhwebo lwamanye amazwe, iinombolo ze-CAS zikwasetyenziswa ukuqinisekisa ukuba abathengi kunye nabathengisi banolwazi olufanayo lwemveliso ethengiswayo. Abaphandi beekhemikhali badinga ukucacisa amanani amachaphaza xa bepapasha uncwadi okanye ukufaka isicelo selungelo elilodwa lomenzi wechiza ukuqinisekisa ukuchaneka kunye nokuqonda kwabo iziphumo zabo.
Indlela yokusebenzisa iinombolo ze-CAS ukufumana ulwazi
Sebenzisa amanani e-CAS, iingcali zecandelo lemichiza zinokubuyisa ngokuchanekileyo ulwazi malunga nezinto zekhemikhali kwiinkcukacha ezininzi. Umzekelo, ulwazi kwiPhepha leDatha yeChemics yeShemikhali (i-SDS), ityhefu, ifuthe lokusingqongileyo, indlela yemveliso kunye nexabiso lentengiso lonke linokufunyanwa ngokukhawuleza kusetyenziswa inombolo ye-CAS. Esi sixhobo sokubuyisa ngokufanelekileyo sixabiseke kakhulu kwiinkampani zokwenza izigqibo zeR & D kunye novavanyo lomngcipheko.
Thelekisa iinombolo ze-CAS kunye nezinye iinkqubo zenani
Nangona iinombolo ze-CAS zisetyenziswa ngokubanzi kwishishini lekhemikhali, ezinye iinkqubo zabaninzi nazo zikhona, njengenani le-UNITER leZizwe eziManyeneyo okanye kwinani le-Einecs Union ye-European Union. Xa kuthelekiswa, iinombolo ze-CAS zinesigqubuthelo esibanzi kunye nokuchaneka okuphezulu. Oku kukhokelele ekugwetyweni kweenombolo ze-CAS kwishishini lekhemikhali kwihlabathi liphela.
Ukuqukumbela
I-CAS, njengesazisi esemgangathweni kwimichiza, iye yaba sisixhobo esingathethekiyo kwishishini lekhemikhali. Ngenombolo ye-CAS, iinkampani zekhemikhali kunye nabaphandi bayakwazi ukulawula kwaye basebenzise ulwazi lwezinto ezithile zekhemikhali ngakumbi nangokufanelekileyo, ngaloo ndlela kukhuthaza ukuphuculwa kweshishini kunye nokuhambela phambili kwezobuchwephesha. Ukuqonda kunye nokusebenzisa ngokuchanekileyo inombolo ye-CAS akunakuphela kuphela ukusebenza ngokufanelekileyo, kodwa kukuphepha ngokufanelekileyo umngcipheko.
