Nhamba yeCAS inorevei? -Kunzwisisa "chitupa chitupa" chechinhu chemakemikari
Nhamba yeCAS inorevei? Muindasitiri yemakemikari, Nhamba yeCAS chinhu chakakosha chinozivisa kemikari chinozivisa chimwe nechimwe chemakemikari, uye chinopihwa neChemical Abstracts Service (CAS) uye yakakosha sechitupa chemunhu. Nekunzwisisa tsananguro, chimiro uye chinangwa chenhamba yeCAS, tinogona kunzwisisa zviri nani basa rayo rakakosha mukutsvaga kwemakemikari, kugadzira uye kutengeserana.
Chii chinonzi CAS Number?
Nhamba yeCAS, inozivikanwa seChemical Abstracts Service Registry Number, identifier yakasarudzika ine nhamba uye dash inotaridza chimwe nechimwe chinozivikanwa chemakemikari. nhamba yeCAS inowanzova nenhamba ine zvikamu zvitatu mufomati “XXX-XX-X”. Semuenzaniso, iyo nhamba yeCAS yemvura ndeye 7732-18-5. chikamu chekutanga chinowanzova nhamba inosvika ku7 manhamba, chikamu chechipiri inhamba ine manhamba maviri, uye chetatu idijiti 1-cheki. Ichi chimiro chinoita kuti nhamba yega yega yeCAS ive yakasarudzika, kuve nechokwadi uye kuenderana mukuzivikanwa kwemakemikari zvinhu muindasitiri yemakemikari yepasirese.
Chinangwa chenhamba yeCAS chii?
Mushure mekunzwisisa zvinorehwa nenhamba yeCAS, isu tinodawo kuziva mashandisiro ayo makuru. Muindasitiri yemakemikari nemakemikari, nhamba dzeCAS dzinoshandiswa zvakanyanya nenzira dzinotevera:
Kuzivikanwa kwezvinhu uye kudzoreredza ruzivo: Sezvo mazita emakemikari zvinhu angasiyana kubva kumutauro kuenda kumutauro kana dunhu nedunhu, nhamba yeCAS, sechiziviso chakasiyana, inodzivirira zvinobudirira kuvhiringidzika kunokonzerwa nekusawirirana uku. Masayendisiti, vaongorori uye mabhizinesi anoshandisa nhamba dzeCAS kukurumidza uye nenzira kwayo kudzoreredza ruzivo rwakadzama nezve chinhu chemakemikari, kusanganisira mamorekuru chimiro, physicochemical properties, nzvimbo dzekushandisa uye zvichingodaro.

Regulatory kutevedzera uye kuchengetedza manejimendi: Pasi rose, nhamba dzeCAS dzinodiwa nemitemo yekutonga kwemakemikari munyika zhinji nematunhu. Semuenzaniso, nhamba yeCAS ruzivo rwakakosha mumakemikari ekuchengetedza data mapepa (SDS). Inobatsira makambani uye vatongi kuti vatore zvirinani kuchengetedza, kutakura uye kushandiswa kwemakemikari kuti ive nechokwadi chekutevedzwa nemirairo yakakodzera uye kuchengetedza zviyero.

Kutengeserana Kwepasi Pose uye Supply Chain Management: Mukutengeserana kwenyika dzese uye kutakura zvigadzirwa zvemakemikari, nhamba yeCAS inoshanda semutauro wakajairika, ichibvisa kusanzwisisika uye kukanganisa kunobva mukusiyana kwemazita emakemikari zvinhu uye kukurudzira kujeka uye kugona mukutengesa cheni.

Nzira yekuwana uye kushandisa nhamba dzeCAS?
Mushure mekunzwisisa zvinorehwa nenhamba yeCAS uye kukosha kwayo, isu tinodawo kuziva nzira yekutsvaga nekushandisa nhamba yeCAS. Pane nzira dzakati wandei dzekuwana nhamba yeCAS:
Kemikari mabhuku uye dhatabhesi: Nhamba dzeCAS dzakatanga kubva kuChemical Abstracts Service database. Nhasi, akawanda epamhepo dhatabhesi, akadai sePubChem, ChemSpider, uye SciFinder, anopa mukana kunhamba dzeCAS uye ruzivo rwavo rwakabatana rwemakemikari.

Vatengesi vemakemikari nevagadziri: Vazhinji vatengesi vemakemikari vanoratidza nhamba dzeCAS mutsananguro yechigadzirwa chavo uye mavara ekubatsira vatengi kuona nekutenga chaiyo chemakemikari chinhu.

Chinokosha pakushandisa nhamba dzeCAS ndechekuti dzakasiyana uye dzinozivikanwa zvakanyanya. Kunyangwe muongorori ari kutsvaga zvinyorwa zvemakemikari kana kambani iri kuona kuti zvigadzirwa zvayo zvinoenderana nepasi rose, nhamba yeCAS chishandiso chiri nyore uye chakavimbika.
Nei nhamba dzeCAS dzakakosha zvakadaro?
Nhamba yeCAS inopfuura nhamba chete, inomiririra mutauro wakajairika wenyika yemakemikari. Kuziva zvinorehwa nenhamba yeCAS kunobatsira kunzwisisa basa rayo repakati mukuzivikanwa kwemakemikari, kutevedzera mutemo, kuchengetedza kuchengetedza uye kutengeserana kwenyika. Munyika yanhasi yepasirese, nhamba yeCAS inoshanda se'chitupa chitupa' chemakemikari, ichiva nechokwadi chekufanana uye pachena mukutonga kwezvinhu zvemakemikari munyika dzese nematunhu.
Mhedziso
Chii chinorehwa nenhamba yeCAS haingori mubvunzo wehunyanzvi hwemakemikari, asiwo inzvimbo yeruzivo ine pesvedzero yakakura. Zvingave mukutsvaga, kugadzira, kana kutengeserana, kushandiswa kwenhamba dzeCAS kunobatsira kuderedza kusanzwisisana, kunatsiridza kushanda zvakanaka, uye kuve nechokwadi chekuchengetedza. Naizvozvo, kujairana nemazano uye mashandisirwo enhamba dzeCAS kwakakosha kune avo vanoshanda mumakemikari kana maindasitiri ane hukama.
