Kodi nambala ya CAS ndi chiyani? -Chidziwitso chapadziko lonse lapansi chazinthu zamankhwala
"Nambala ya CAS" ndi lingaliro lodziwika bwino komanso lofunika kwambiri pamakampani opanga mankhwala, kaya ndinu katswiri wamankhwala, wofufuza kapena katswiri wopanga mankhwala. Kaya ndinu katswiri wamankhwala, wofufuza kapena katswiri wogwira ntchito m'makampani opanga mankhwala, ndikofunikira kuti mudziwe ndikugwiritsa ntchito nambala ya CAS.Nambala ya CAS ndi chiyani? N’chifukwa chiyani kuli kofunika kwambiri? M’nkhaniyi tikambirana mafunso amenewa mozama.
1. Tanthauzo ndi chiyambi cha nambala ya CAS
Nambala ya CAS, yomwe imadziwika kuti Chemical Abstracts Service Number, ndi nambala yozindikiritsa yapadera yomwe imaperekedwa ku mankhwala aliwonse ndi Chemical Abstracts Service (CAS) ku US Nambala ya CAS nthawi zambiri imakhala ndi magulu atatu a manambala olekanitsidwa ndi chingwe chachifupi chopingasa, mwachitsanzo 123-45-6. Dongosolo lowerengera manambalali linakhazikitsidwa mu 1965 kuti lipereke njira yofananira komanso yokhazikika yodziwira zinthu zamankhwala padziko lonse lapansi. 2.
2. Kapangidwe ndi tanthauzo la manambala a CAS
Kapangidwe ka nambala ya CAS ndi yosavuta komanso yowongoka, koma ili ndi tanthauzo lakuya kumbuyo kwake. Iliyonse mwa magulu atatu oyamba a manambala imayimira chidziwitso chosiyana: gulu loyamba la manambala nthawi zambiri limasonyeza dongosolo lomwe mankhwala enaake amaikidwa m'gulu lake; gulu lachiwiri la manambala limagwiritsidwa ntchito kupititsa patsogolo kugawa kwazinthu; ndipo nambala yachitatu ndi nambala yotsimikizira kuti nambalayo ndi yolondola komanso yapadera. Ndi nambala iyi, mankhwala aliwonse amatha kudziwika bwino, kaya ndi organic compound kapena mchere wosavuta.
3. Kugwiritsa ntchito manambala a CAS mumakampani opanga mankhwala
Nambala ya CAS ili ndi ntchito zambiri m'makampani opanga mankhwala. Amagwiritsidwa ntchito pogula ndi kugulitsa mankhwala. Monga momwe chiwerengero cha CAS chimagwiritsidwira ntchito padziko lonse lapansi, chimapangitsa kuti malonda a mankhwala azikhala osavuta komanso amapewa chisokonezo chomwe chimabwera chifukwa cha kusiyana kwa mayina a mankhwala.Nambala ya CAS imagwiritsidwanso ntchito pofufuza ndi kupanga zinthu za mankhwala, zomwe zimathandiza ochita kafukufuku kuti apeze zambiri zazinthu ndi zolemba zokhudzana nazo, motero kupititsa patsogolo luso la kafukufuku.
4. Malamulo ndi chitetezo cha nambala za CAS
Kuphatikiza pakugwiritsa ntchito kwake kosiyanasiyana, nambala ya CAS imakhalanso ndi gawo lofunikira pamalamulo ndi chitetezo. M'malamulo a mankhwala, mayiko ndi zigawo zambiri zimafuna kuti opanga ndi ogulitsa mankhwala apereke manambala a CAS kuti awonetsetse kuti zinthu zikutsatiridwa, ndipo manambala a CAS amagwiritsidwanso ntchito mu Safety Data Sheets (SDS) kuti mankhwala apereke chidziwitso chofunikira cha chitetezo kwa ogwira ntchito ndi ogula.
5. Chifukwa chiyani manambala a CAS ndi ofunika kwambiri pa kayendetsedwe ka mankhwala
Kasamalidwe ka mankhwala azinthu zakhala zovuta kwambiri pakupanga mankhwala amakono. Pamene kudalirana kwa mayiko kukuchulukirachulukira komanso miyezo yoyendetsera zinthu zama mankhwala imasiyanasiyana kumayiko ndi dera, nambala ya CAS imagwira ntchito ngati chizindikiritso chofananira kuthandiza makampani opanga mankhwala kuti azigwira bwino ntchito m'malo osiyanasiyana azamalamulo ndi owongolera, ndipo imathandizira kutsata ndi kuyang'anira kuyika ndi kugwiritsa ntchito mankhwala, kuchepetsa ziwopsezo za chilengedwe ndi chitetezo.
6. Momwe mungapezere ndi kugwiritsa ntchito manambala a CAS
Manambala a CAS nthawi zambiri amapezeka pofufuza database yoyenera ya Chemical Abstracts Service (CAS). Ndikofunika kuti akatswiri adziwe momwe angagwiritsire ntchito bwino zinthuzi. M'malo mwake, makampani opanga mankhwala nthawi zambiri amalembetsa ku nkhokwe za CAS kuti apeze zidziwitso zaposachedwa pazamankhwala munthawi yeniyeni. Mabungwe ambiri ofufuza ndi mayunivesite amagwiritsanso ntchito manambala a CAS pochita kafukufuku ndikuwonetsetsa kuti deta ikulondola komanso kusasinthika.
Mapeto
Nambala ya CAS ndiyofunikira kwambiri pamakampani opanga mankhwala. Sikuti amangopereka chizindikiritso chovomerezeka padziko lonse cha mankhwala, komanso amathandizira kwambiri pakuwongolera mankhwala, kutsata malamulo, komanso kupanga kotetezeka. Chifukwa chake, kaya ndinu msilikali wakale wamakampani kapena novice, kumvetsetsa mozama kwa nambala ya CAS ndikugwiritsa ntchito kwake kudzakhudza kwambiri ntchito yanu.
