Kev Tshawb Fawb Txog Kev Lag Luam ntawm Cov Ntsiab Lus Qhia Txog Kab

Kuv,Kev tshuaj xyuas cov hlau uas tsis yog ferrous

Txhua lub lim tiam: Txhua hli:

1)Zinc sulfate

  ① Cov khoom siv raw: Zinc hypooxide: Tus nqi pauv tseem siab. Kev xav txog kev lag luam macroeconomic hauv kev ua lag luam sov so, ua rau cov nqi zinc nce ntxiv thiab cov nqi nce ntxiv.

② Tus nqi sulfuric acid tseem ruaj khov ntawm qib siab thoob plaws lub tebchaws lub lim tiam no. Soda ash: Tus nqi ruaj khov lub lim tiam no. ③ Sab kev thov tseem ruaj khov. Muaj kev nyiam rau kev muab zinc thiab kev thov kom sib npaug, thiab muaj qhov ua tau me ntsis ntawm kev poob qis ntawm zinc hauv lub sijhawm luv luv - mus rau nruab nrab. Tus nqi zinc xav tias yuav khiav ntawm 22,000 txog 22,500 yuan ib tuj lub lim tiam tom ntej.

Hnub Monday, tus nqi ua haujlwm ntawm cov neeg tsim cov zinc sulfate dej yog 89% thiab tus nqi siv peev xwm yog 69%, tseem nyob ruaj khov piv rau lub lim tiam dhau los. Cov xaj ntawm cov chaw tsim khoom loj tau teem sijhawm mus txog nruab nrab Lub Kaum Hli. Kev thov tau nce siab. Australia nyob rau hauv lub caij thov siab tshaj plaws. Central America tau nce kev thov nrog rau lub caij los nag. Kev xa khoom nruj heev. Kev thov maj mam rov zoo thiab cov nqi khoom siv raw khoom ruaj khov. Cov nqi yuav nyob twj ywm ntawm qib siab.

Cov neeg siv khoom raug qhia kom npaj cov khoom kom zoo ua ntej raws li lawv cov khoom muaj.

2）Manganese sulfate

 Hais txog cov khoom siv raw: ① Tus nqi ntawm cov hlau manganese tseem ruaj khov nrog kev hloov pauv loj heev. Thaum hnub so los txog, cov chaw tsim khoom pib npaj cov hlau thiab khaws cov khoom ib qho tom qab ib qho. Qhov chaw nug ntawm cov chaw nres nkoj tau ua haujlwm. Cov lus hais txog cov khoom lag luam tau ruaj khov thiab qhov kev lag luam tau maj mam ua raws.

②Tus nqi ntawm cov kua qaub sulfuric tseem ruaj khov ntawm qib siab.

Lub lim tiam no, tus nqi ua haujlwm ntawm cov chaw tsim khoom manganese sulfate yog 76%, txo qis 5% piv rau lub lim tiam dhau los. Kev siv peev xwm yog 49%, txo qis 3% los ntawm lub lim tiam dhau los.

Kev muab khoom ntawm cov khoom seem heptahydrate ferrous sulfate yog nruj, nrog kev txhawb nqa zoo los ntawm cov nqi khoom siv raw thiab kev xa khoom nruj los ntawm cov chaw tsim khoom. Xav txog cov khoom muag tsis ntev los no ntawm cov tuam txhab thiab cov nqi ua haujlwm sab saud, ferrous sulfate xav tias yuav nce siab hauv lub sijhawm luv luv.

4）Tooj liab sulfate/tooj liab chloride yooj yim

Cov Khoom Siv Raw: Tus nqi tooj liab yuav nce siab heev lub lim tiam no vim tias lub chaw ua tooj liab loj hauv Indonesia tseem kaw, ua rau muaj kev txhawj xeeb txog kev muab khoom. Kev cia siab tias yuav nce 2.5 feem pua ​​​​​​ntawm txoj cai LME lub lim tiam no tau txhawb kev ntseeg siab thoob plaws hauv kev lag luam hlau thiab txhim kho qhov kev xav tau. Kev kaw ntev ntawm lub chaw ua tooj liab thib ob loj tshaj plaws hauv ntiaj teb tuaj yeem ua rau kev ua lag luam nruj. Lub caij no, kev cia siab ntawm Asmeskas kev txo qis ntawm txoj cai nyiaj txiag tau txhawb kev ntseeg siab thoob plaws hauv kev lag luam hlau thiab txhim kho qhov kev xav tau. Zoo rau tus nqi tooj liab, uas xav tias yuav tseem siab, muaj zog thiab tsis ruaj khov hauv lub sijhawm luv luv. Qhov ntau thiab tsawg rau qhov ua haujlwm tseem ceeb ntawm Shanghai tooj liab: 81,050-81,090 yuan / ton.

Los ntawm lub zeem muag loj: Kev cia siab tias Federal Reserve yuav txo tus nqi paj laum tau ua rau tus nqi tooj liab nce siab hauv tebchaws thiab thoob ntiaj teb. Federal Reserve yuav txo tus nqi paj laum thaum lub Cuaj Hli yog qhov tseeb, thiab kev ua lag luam tau teev tus nqi raws li kev cia siab tias yuav txo peb tus nqi hauv ib xyoos. Cua sov loj tau tsav lub chaw nqi tooj liab kom nce qeeb qeeb. Hauv cov ntsiab lus tseem ceeb, muaj kev cuam tshuam me me ntawm qhov kawg ntawm kev khawb av, thiab kev tsis sib haum xeeb ntawm kev muab khoom thiab kev thov ntawm tooj liab electrolytic hauv tebchaws tau loj hlob tuaj. Thaum lub sijhawm xa khoom los txog, tseem muaj qhov sib txawv ntawm tus lej ntawm cov ntawv txais nyiaj hauv tsev khaws khoom uas xav tau los phim cov haujlwm ntawm daim ntawv cog lus tooj liab Shanghai lub hlis tam sim no thiab cov ntawv txais nyiaj hauv tsev khaws khoom yav tom ntej uas twb muaj lawm, uas tau thawb tus nqi ntawm daim ntawv cog lus lub hlis tam sim no. Thaum kaw kev lag luam, daim ntawv cog lus tooj liab Shanghai 2509 kaw ntawm 81,390 yuan ib tuj. Tus nqi tooj liab LME tau tawg hla $ 10,134 ib tuj cim thiab tom qab ntawd mus txog qhov siab tshaj plaws ntawm $ 10,100 ib tuj, ntaus qhov siab tshaj plaws ntawm $ 10,126 ib tuj.

Kev daws teeb meem etching: Qee cov chaw tsim khoom siv raw khoom sab saud tau ua kom cov peev txheej ntws sai dua los ntawm kev ua cov tshuaj etching tob rau hauv daim txhuam cev tooj liab lossis tooj liab hydroxide. Qhov feem pua ​​ntawm kev muag khoom rau kev lag luam tooj liab sulfate tau txo qis, thiab tus lej kev lag luam tau mus txog qhov siab tshiab. Cov nqi tooj liab yuav nce siab dua li qhov kev xav ntawm macro, thawb cov nqi khoom siv raw rov qab.

Nws raug pom zoo kom ua cov phiaj xwm yuav khoom thiab khaws cia sab nraud ntawm kev thov kom tau ua xya hnub ua ntej ua ke nrog cov khoom muag.

10） Cov ntsev Cobalt/potassium chloride/potassium carbonate/calcium formate/iodide

1. Cov ntsev Cobalt: Cov nqi khoom siv raw: Kev txwv tsis pub xa tawm ntawm Congolese (DRC) txuas ntxiv mus, cov nqi cobalt nruab nrab txuas ntxiv nce, thiab cov nqi siab tau dhau mus rau sab qis.

Lub lag luam ntsev cobalt zoo rau lub lim tiam no, nrog rau cov lus hais tseem nce siab thiab kev muab khoom nruj, feem ntau yog tsav los ntawm kev muab khoom thiab kev thov. Kev lag luam ntawm cov ntsev cobalt thiab oxides yuav nce ntxiv rau lub lim tiam tom ntej. Tsom mus rau qhov kev hloov pauv tshiab ntawm txoj cai xa khoom tawm hauv Democratic Republic of the Congo thaum lub Cuaj Hli. Tam sim no, cov khoom cobalt nruab nrab tsuas yog kov $ 14 ib phaus, thiab qee tus neeg sab hauv kev lag luam txhawj xeeb tias tus nqi tsis tau mus txog qib uas tau xav tseg los ntawm sab Congolese, thaum qhov qeeb ntawm kev sib tham txog quota yuav ua rau kev txhawj xeeb ntawm kev ua lag luam ntau ntxiv txog kev ncua sijhawm ntxiv.

2. Tus nqi tag nrho ntawm potassium chloride tsis muaj kev hloov pauv tseem ceeb. Kev ua lag luam qhia tau tias ob qho tib si kev muab khoom thiab kev thov tsis muaj zog. Kev muab khoom ntawm cov peev txheej ua lag luam tseem nruj, tab sis kev txhawb nqa kev thov los ntawm cov chaw tsim khoom qis dua tseem tsawg. Muaj kev hloov pauv me me hauv qee tus nqi siab, tab sis qhov dav tsis loj. Tus nqi tseem ruaj khov ntawm qib siab. Tus nqi ntawm potassium carbonate hloov pauv nrog tus nqi ntawm potassium chloride.

3. Tus nqi ntawm calcium formate tau qis dua lub lim tiam no. Cov chaw tsim cov formic acid nyoos rov pib tsim khoom thiab tam sim no nce cov chaw tsim cov formic acid, ua rau muaj peev xwm ua cov formic acid ntau ntxiv thiab muaj ntau dhau. Nyob rau lub sijhawm ntev, tus nqi calcium formate poob qis.

4 Tus nqi Iodide ruaj khov lub lim tiam no piv rau lub lim tiam dhau los.
