Chii chinonzi CAS nhamba? -Chitupa chepasi rose chemakemikari zvinhu
Iyo "CAS nhamba" ipfungwa yakajairika uye yakakosha muindasitiri yemakemikari, ungave uri kemisitiri, muongorori kana nyanzvi yekugadzira makemikari. Ungave uri kemisiti, muongorori kana nyanzvi inoshanda muindasitiri yemakemikari, zvakakosha kuti uzive uye ushandise nhamba yeCAS.Nhamba yeCAS chii? Nei zvichikosha kudaro? Muchinyorwa chino, tichaongorora mibvunzo iyi zvakadzama.
1. Tsanangudzo uye kwakabva nhamba yeCAS
Nhamba yeCAS, inozivikanwa seChemical Abstracts Service Number, inhamba yakasarudzika inopihwa kumakemikari ega ega neChemical Abstracts Service (CAS) muUS Nhamba yeCAS inowanzova nemaseti matatu enhamba akapatsanurwa nemutsara mupfupi wakachinjika, semuenzaniso 123-45-6. Iyi hurongwa hwekuverengera hwakatangwa muna 1965 kuti ipe yunifomu uye yakamisikidzwa nzira yekuziva makemikari zvinhu pasi rose. 2.
2. Mamiriro uye zvinoreva nhamba dzeCAS
Chimiro chenhamba yeCAS iri nyore uye yakatwasuka, asi ine chirevo chakadzama kuseri kwayo. Imwe neimwe yezvikamu zvitatu zvekutanga zvenhamba inomiririra ruzivo rwakasiyana: seti yekutanga yenhamba inowanzotaridza kurongeka uko chimwe chinhu chemakemikari chinoiswa muchikamu chayo; yechipiri seti yenhamba inoshandiswa kuwedzera kupatsanura mhando yezvinhu; uye yechitatu seti yenhamba idijiti cheki inovimbisa huchokwadi uye hwakasiyana hwenhamba. Nenhamba iyi, chero chinhu chemakemikari chinogona kunyatsozivikanwa, chingave chiri chakaomesesa cheorganic compound kana munyu wakapfava.
3. Kushandiswa kwenhamba dzeCAS muindasitiri yemakemikari
Nhamba yeCAS ine huwandu hwakawanda hwekushandisa muindasitiri yemakemikari. Inoshandiswa mukutenga nekutengesa kwemakemikari. Sezvo nhamba yeCAS ichishandiswa pasi rose, inoita kuti kutengeserana kwemakemikari kuve nyore uye kudzivirira kuvhiringidzika kunokonzerwa nekusiyana kwemazita emakemikari.Nhamba yeCAS inoshandiswawo mukutsvakurudza nekugadzirwa kwezvinhu zvemakemikari, izvo zvinobvumira vatsvakurudzi kuwana ruzivo rwakakwana rwechinhu uye zvinyorwa zvinoenderana, nokudaro kuvandudza kushanda kwekutsvakurudza.
4. Mutemo uye kuchengeteka zvikamu zveCAS nhamba
Pamusoro pehuwandu hwayo hwekushandisa, nhamba yeCAS inoitawo basa rakakosha mune zvemutemo uye kuchengetedza zvinhu. Mumitemo yemakemikari, nyika zhinji nematunhu zvinoda kuti vanogadzira nevanopinza makemikari vape nhamba dzeCAS kuti vaone kuteererwa kwechigadzirwa, uye nhamba dzeCAS dzinoshandiswawo muSafety Data Sheets (SDS) kuti makemikari ape ruzivo rwakakosha rwekuchengetedza kuvashandi nevatengi.
5. Sei nhamba dzeCAS dzakakosha pakugadzirisa zvinhu zvemakemikari
Kutungamirirwa kwemakemikari zvinhu kwave kunowedzera kuoma mukugadzirwa kwemakemikari kwemazuva ano. Sezvo kudyidzana kwepasi rose kunowedzera uye zviyero zvekutonga kwemakemikari zvinhu zvichisiyana kubva kunyika nenyika uye dunhu nedunhu, nhamba yeCAS inoshanda sechiratidzo cheunifomu kubatsira makambani emakemikari kushanda zvakanaka munzvimbo dzakasiyana dzemutemo uye dzemitemo, uye inofambisa kuteedzera uye kutonga kwemakemikari ezvigadzirwa uye mashandisiro, kuderedza dzingangoitika nharaunda nekuchengetedza njodzi.
6. Mawaniro nekushandisa nhamba dzeCAS
Nhamba dzeCAS dzinowanzo kuwanikwa nekutsvaga yakakodzera Chemical Abstracts Service (CAS) database. Zvakakosha kuti nyanzvi dzizive mashandisirwo ezviwanikwa izvi nemazvo. Mukuita, makambani emakemikari anowanzo kunyorera kuCAS dhatabhesi kuitira kuti awane ruzivo rwechizvino-zvino nezvemakemikari zvinhu munguva chaiyo. Mazhinji masangano ekutsvagisa nemayunivhesiti anoshandisawo nhamba dzeCAS kuita tsvakiridzo uye kuona chokwadi che data uye kuenderana.
Mhedziso
Nhamba yeCAS ndeyekukosha kusingadzoreki muindasitiri yemakemikari. Haisi chete inopa ID inogamuchirwa pasi rose yechinhu chemakemikari, asi inoitawo basa rakakosha mukutonga kwemakemikari, kutevedzera mutemo, uye kugadzirwa kwakachengeteka. Naizvozvo, kunyangwe iwe uri muindasitiri veteran kana novice, kunzwisisa kwakadzama kwenhamba yeCAS uye mashandisiro ayo anozokanganisa zvakanyanya pabasa rako.
