Kodi CAS ndi chiyani?
CAS imayimira Chemical Abstracts Service, database yovomerezeka yokhazikitsidwa ndi American Chemical Society (ACS.) Nambala ya CAS, kapena nambala ya registry ya CAS, ndi chizindikiritso cha manambala chapadera chomwe chimagwiritsidwa ntchito kuyika chizindikiro cha mankhwala, mankhwala, kalembedwe kazachilengedwe, ma polima, ndi zina zambiri. . M'makampani opanga mankhwala, nambala ya CAS ndi chida chofunikira kwambiri chifukwa imathandiza asayansi ndi mainjiniya kuzindikira mosavuta komanso molondola komanso kupeza zinthu zina zamankhwala.
Kufunika kwa Nambala ya CAS
M'makampani opanga mankhwala, kuzindikira ndi kutsata zinthu za mankhwala ndi chimodzi mwazinthu zofunika kwambiri pa ntchito ya tsiku ndi tsiku. Popeza kuti mankhwala amatha kukhala ndi mayina angapo, mayina odziwika kapena mayina amtundu, izi zitha kuyambitsa chisokonezo. nambala ya CAS imathetsa vutoli popereka nambala yokhazikika yomwe imagwiritsidwa ntchito padziko lonse lapansi. Mosasamala kanthu za kusintha kwa dzina kapena chinenero cha mankhwala, nambala ya CAS nthawi zonse imagwirizana ndi chinthu china. Njira yodziwikirayi ndiyofunikira m'magawo angapo kuphatikiza kafukufuku ndi chitukuko, kagulitsidwe, kupanga ndi kutsata malamulo.
Kapangidwe ka nambala ya CAS ndi kufunikira kwake
Nambala ya CAS nthawi zambiri imakhala ndi magawo atatu: manambala awiri ndi cheke. Mwachitsanzo, nambala ya CAS ya madzi ndi 7732-18-5. Kapangidwe kameneka, ngakhale kakuwoneka kosavuta, kamakhala ndi chidziwitso chochuluka. Manambala atatu oyambirira amaimira malo a chinthu mu Chemical Abstracts Service, gulu lachiwiri la manambala limasonyeza zinthu zapadera za chinthucho, ndipo cheke chomaliza chimagwiritsidwa ntchito kutsimikizira kuti manambala am'mbuyomu ndi olondola. Kumvetsetsa kapangidwe ka manambala a CAS kumathandiza akatswiri kuti amvetsetse ndikuzigwiritsa ntchito mwachangu.
CAS mu Chemical Viwanda
Nambala za CAS zimagwiritsidwa ntchito kwambiri pakulembetsa, kuwongolera ndi kugulitsa zinthu zama mankhwala. Panthawi yolembetsa ndi kuitanitsa katundu wa mankhwala, manambala a CAS nthawi zambiri amafunidwa ndi mabungwe olamulira kuti atsimikizire chitetezo ndi kuvomerezeka kwa mankhwala. Pazamalonda apadziko lonse lapansi, manambala a CAS amagwiritsidwanso ntchito kuwonetsetsa kuti ogula ndi ogulitsa ali ndi chidziwitso chofanana cha malonda omwe akugulitsidwa. Ofufuza a mankhwala amayeneranso kutchula manambala a CAS posindikiza mabuku kapena kufunsira ma patent kuti atsimikizire kulondola ndi kutsimikizika kwa zomwe apeza.
Momwe mungagwiritsire ntchito manambala a CAS kuti mupeze zambiri
Pogwiritsa ntchito manambala a CAS, akatswiri amakampani opanga mankhwala amatha kupezanso zambiri zokhudzana ndi mankhwala m'mankhokwe angapo. Mwachitsanzo, chidziwitso cha mankhwala a Safety Data Sheet (SDS), kawopsedwe, kukhudzidwa kwa chilengedwe, njira yopangira ndi mtengo wamsika zitha kupezeka mwachangu pogwiritsa ntchito nambala ya CAS. Kuthekera kopeza kumeneku ndikopindulitsa kwambiri kumakampani popanga zisankho za R&D ndikuwunika zoopsa.
Kuyerekeza manambala a CAS ndi machitidwe ena owerengera
Ngakhale manambala a CAS amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, njira zina zowerengera ziliponso, monga nambala ya UN ya United Nations kapena nambala ya EINECS ya European Union. Poyerekeza, manambala a CAS ali ndi nkhani zambiri komanso zolondola kwambiri. Izi zapangitsa kuti manambala a CAS achuluke kwambiri pamakampani opanga mankhwala padziko lonse lapansi.
Mapeto
CAS, monga chizindikiritso chokhazikika cha mankhwala, yakhala chida chofunikira kwambiri pamakampani opanga mankhwala. Kupyolera mu manambala a CAS, makampani opanga mankhwala ndi ofufuza amatha kuyang'anira ndi kugwiritsa ntchito chidziwitso cha mankhwala molondola komanso moyenera, motero amalimbikitsa chitukuko cha mafakitale ndi kupita patsogolo kwa teknoloji. Kumvetsetsa ndi kugwiritsa ntchito bwino nambala ya CAS sikungangowonjezera magwiridwe antchito, komanso kupewa ngozi zomwe zingachitike.
