Mercury (Hg) Kugadzira, Zvitubu & Indasitiri Overview | United Chemical

ziviso

Mercury (Hg) isimbi yakakosha munhoroondo asi ine ngozi zvikuru. Yayo yakasarudzika zvivakwa - mvura pane tembiricha yekamuri, yakakwira magetsi conductivity uye kugona kwealloying - yakatungamira mukushandiswa kwakakura kwemaindasitiri munguva yakapfuura. Kuwedzera kuziva nezvezvakatipoteredza uye hutano njodzi dzine chekuita ne Mercury zvakakonzera zviito zvenyika dzakawanda zvakadai seMinamata Convention kurambidza kana kubvisa vakawanda NGONI kushandisa uye kukurudzira kudzokorodza uye kudzora kusvibiswa.

Nyaya yekambani iyi na United Chemical inopa yakajeka, pfupiso yehunyanzvi ye Mercury masosi uye nzira dzekudzoreredza, hunhu hwechigadzirwa-mhando uye kuenzanisa nekwakabva, iyo indasitiri kukosha kweketani, kudzora uye kutengeserana nzvimbo, uye inoshanda kutevedzera kwekambani uye kurudziro-yekutarisira njodzi.

Safety note: Mercury nemakomponi ayo ane neurotoxic uye anoramba akamira kwezvakatipoteredza. Chero kubata, kudzoreredza, kutakurwa kana kushandiswa kunofanirwa kutevedzera mitemo yenyika, zvibvumirano zvepasi rose nemirairo yezvinhu zvine njodzi. 

1. Chii chinonzi mercury? (Pfupi)

Elemental mercury (Hg) isimbi yakakora iri paambient mamiriro uye inogona kupfakanyika nekupararira munzvimbo. Mercury inowanikwa mumhando dzakawanda:

• Elemental mercury (Hg⁰) - simbi, inoputika;

• Inorganic mercury munyu - semuenzaniso, mercuric chloride (HgCl₂);

• Organic mercury - yakadai semethylmercury, iyo bioaccumulates mumaketani ezvokudya uye inokonzera njodzi dzakakomba dzehutano.

Mercury yakaburitswa mumhepo nemvura inogona kushandurwa uye kuunganidzwa, zvichikonzera kukanganisa kwehupenyu uye hutano hwevanhu.

2. Main masosi uye kudzoreredza zvikamu (yepamusoro-chikamu chepamusoro)

Global mercury supply inonyanya kutorwa kubva yekutanga migodhi (cinnabar/HgS) uye recycled nzizi (industrial by-products uye tsvina yakaunganidzwa). Iwo akakosha masosi mapoka ndeaya:

1. Mugodhi wekutanga uye kunyungudutsa (cinnabar)

• tsananguro: Historical cinnabar (HgS) kuchera uye kunyungudutsa goho elemental mercury nekudziisa uye condensation. Zvivakwa zvemazuva ano zvinowirirana zvinogona kugadzira yakakwira-purity mercury zvichitevera kurapwa kwakakwana.

• Kunetseka: Kunyungudutswa kusingadzorwi kunokonzera kusvibiswa kwakanyanya uye njodzi dzehutano; nyika zhinji dzinoganhurira kana kurambidza mabasa akadaro.

2. Indasitiri ne-chigadzirwa kupora uye yakadzorwa kudzokorodza

• tsananguro: Mercury iri kuwedzera kutorwa kubva kumarara akaunganidzwa-marambi efluorescent, switch uye relays, zvishandiso zvekurapa, zvemagetsi uye lab tsvina-zvino inonatswa munzvimbo dzakadzorwa.

• Chazvakanakira: Kudzokorodza kunoderedza kuremerwa kwezvakatipoteredza uye kunonatsiridza kuteedzera uye kutevedza kwemitemo.

3. Artisanal uye diki-scale migodhi yegoridhe (ASGM)

• tsananguro: Mune mamwe matunhu ASGM inoshandisa mercury kugadzira amalgams ekudzoreredza goridhe. 

• urongwa: ASGM mercury kushandiswa ndicho chinangwa chikuru chekuderedza pasi peMinamata Convention uye mapurogiramu enyika anokurudzira dzimwe nzira.

4. Historic stocks uye midziyo kubvisa

• tsananguro+

3. Chitubu / chigadzirwa chemhando yekuenzanisa uye yakakosha metrics

Zvikwata zvekutenga uye zvekuteerera zvinofanirwa kukoshesa anotevera metrics muZvitupa zveAnalysis (COA):

• Hg zvemukati / kuchena kwekutanga (%);

• Organic mercury (methylmercury) zvakasara;

• Volatility uye vapor-pressure inoenderana nekuchengetedza paramita;

• Inorganic tsvina (Se, Pb, S masanganiswa, zvikamu);

• Unyoro uye michina inosvibisa;

• Fomu uye kurongedza (elemental fluid Hg, munyu, alloys; midziyo yemidziyo).

High-level kuenzanisa nekwakabva:

• Kucherwa kwekutanga (zvirimwa zvinowirirana): Kuchena kwepamusoro kunogoneka kana kuburitswa uye kurapwa kwemarara kuchidzorwa; kutevedza mitemo kwakakosha.

• Regulated recycling: Nekunatswa kwemazuva ano, recycled mercury inogona kusangana nepamusoro-kuchena zvakatemwa uye inosarudzwa nekuda kwezvikonzero zvezvakatipoteredza.

• Nhoroondo/kubvisa zvinyorwa: Variable quality; kazhinji kunoda kumwe kucheneswa.

• ASGM zvinyorwa: Yakasvibiswa zvakanyanya uye isingagamuchirwe kune zviri pamutemo zvekutengesa cheni.

4. Indasitiri kukosha cheni (kumusoro - pakati perwizi - zasi)

Kumusoro - masosi nemidziyo

• Sources: cinnabar ores, marara emaindasitiri (marambi, switch, midziyo yekurapa), masheya enhoroondo.

• Zvishandiso & masevhisi: yakavharwa condensation/capture systems, adsorption/absorption units, yekunatsa michina, certified test labs, zvine njodzi kurongedza zvinhu uye logistics.

Midstream - kunatsa, kuyedza & kutengeserana

• mabasa: kunyungudutsa / kunatsa, kuedzwa kwerabhoritari (COA/MSDS), kurongedza uye kunyora, kutevedzera kunze kwenyika uye zvinhu.

• Zvinhu zvinokosha: mvumo, kudzora kuburitsa, kutungamira kwehutano hwebasa uye kutevedza kwekutakura.

Kudzika - maapplication & ekutsiva maitiro

• Applications: niche yakakwirira-chaiyo zviridzwa, mamwe makemikari catalysts, tsvakurudzo; kare mukuvheneka uye kushandura (ikozvino kwakatsiviwa zvakanyanya).

• Trend: kukurumidza kutorwa kwe mercury-isina tekinoroji (maLED, solid-state switch, mamwe macatalysts) uye inofambiswa-inofambiswa chikamu-kunze mukushandiswa kwakawanda.

5. Regulatory & trade landscape (muchidimbu)

• Minamata Convention: iyo yakakosha yemitemo yenyika inoda matanho ekudzikisa uye pakupedzisira kubvisa mecury kuburitswa, kukurudzira kudzokorodza uye kubata masheya.

• Market trend: kudonha kuri kudiwa kwekutanga mercury nekuwedzera kuvimba kune akadzokororwa, anowirirana masosi; Kutengeserana zvisiri pamutemo kwemecury uye zvisina kurongeka ASGM zvinoramba zviri zvekutanga.

• Trade kungwarira: zvinotengeswa kunze kwenyika zvinofanirwa kusangana nezvinodiwa nenyika, zvine njodzi-yekutakura zvinhu (IATA/IMDG), uye mavambo ekutsvaga.

6. Indasitiri njodzi, kutevedzera zvinotanga & kurudziro

1. kutevedzera: chengetedza kurongeka kwakazara neMinamata Convention uye mirau yenzvimbo-yakanyorwa traceability yemecury masosi nenzvimbo.

2. Kurudzira kushandiswa patsva: dyara muunganidzwa wakadzorwa uye kukwenenzvera zvivakwa kuti upe inoenderana yakadzokororwa mecury.

3. Chengetedza hutano & nharaunda: simbisa kutariswa kwebasa, kudzivirira kudonha, mhinduro yechimbichimbi uye kuita nharaunda.

4. Tsigira kutsiva: shanda nevatengi kutora mercury-yemahara tekinoroji uye nekupa kubvisa / kudzoreredza-asset rutsigiro.

5. Quality control & traceability: ipa COA/MSDS nekutakura kwega kwega uye simbisa batch traceability.

6. Kuchinjisa njodzi: shandisa inishuwarenzi yemhosva yezvakatipoteredza uye inishuwarenzi yekufambisa.

United Chemical yakazvipira kuita basa, rinoenderana uye rinoziva zvakatipoteredza nezvinhu zvine chekuita nemekiyuri. Zvatinokoshesa zvinosanganisira:

• kukoshesa kudzokororwa kwakadzorwa uye kuderedza kuvimba nekutanga kutorwa;

• kuchengetedza kwakasimba kudzora kwemhando, zvinyorwa uye traceability;

• kupa vatengi zvinyorwa zvekuteerera, zano rehunyanzvi uye kudzidziswa kubata zvakachengeteka;

• kudyidzana kusimudzira dzimwe nzira uye kuderedza njodzi dzemercury mumaindasitiri ari pasi pemvura.
