Lub caij nplooj ntoos hlav cua sov, thiab txhua yam rov qab zoo. Cov teb thiab cov tsev cog khoom qhia txog qhov xwm txheej ntawm lub caij nplooj ntoos hlav thaum ntxov. Thaum huab cua sov, kev tsim khoom ua liaj ua teb tau nce qib los ntawm sab qab teb mus rau sab qaum teb, thiab lub caij siab tshaj plaws rau cov chiv phosphate kuj tau los txog. "Txawm hais tias lub caij chiv raug ncua xyoo no, qhov kev ua haujlwm ntawm kev lag luam chiv phosphate tau nce ntxiv tom qab Lub Caij Nplooj Ntoos Hlav. Kev muab cov chiv phosphate tau lees paub, uas tuaj yeem ua tau raws li qhov xav tau ntawm kev ua liaj ua teb thiab kev siv caij nplooj ntoos hlav Hauv qhov xwm txheej ntawm kev txuag tag nrho, tus nqi ntawm cov chiv phosphate thaum lub caij nplooj ntoos hlav plowing yuav nyob twj ywm.
Kev lav phib xaub thiab kev thov khoom muaj zog
Tom qab Lub Caij Nplooj Ntoos Hlav, nrog rau qhov kev thov ntau ntawm kev ua liaj ua teb caij nplooj ntoos hlav pib ib qho tom qab ib qho, ua ke nrog kev siv txoj cai hauv tebchaws ntawm kev ua kom muaj kev muab khoom thiab tus nqi ruaj khov, qhov kev ua haujlwm tag nrho ntawm kev lag luam chiv phosphate txuas ntxiv mus, thiab cov zis maj mam nce. "Txawm hais tias qee lub tuam txhab tau ntsib teeb meem hauv kev yuav khoom phosphate ore, feem ntau ntawm lawv muaj roj nyoos txaus xws li phosphate ore, sulfur thiab synthetic ammonia, thiab kev tsim cov nroj tsuag ib txwm muaj. Qhov kev siv peev xwm tag nrho ntawm kev lag luam monoammonium phosphate thiab diammonium phosphate yog ze li ntawm 70%. "" Wang Ying hais.
Qhov muaj ntau dhau ntawm monoammonium phosphate thiab diammonium phosphate hauv Suav teb yog qhov loj heev, yog li txawm hais tias muaj ntau qhov kev xa khoom txhua xyoo, nws tseem tuaj yeem lav qhov kev xa khoom hauv tsev. Tam sim no, kev lag luam chiv phosphate hauv qhov kev ua haujlwm tsis ncav cuag 80% ntawm cov ntaub ntawv, tsis yog tsuas yog ua kom tau raws li qhov xav tau hauv tsev, tab sis kuj tseem yuav tsum xa khoom raws li kev txiav txim, yog li tsis muaj teeb meem hauv kev xa khoom ua liaj ua teb caij nplooj ntoos hlav.
Raws li Li Hui, tus thawj coj ntawm Tuam Tshoj Fertilizer Information Center, Daim Ntawv Qhia Txog Kev Siv Tshuaj Chiv No. 1 uas nyuam qhuav tso tawm dua ib zaug ntxiv hais txog qhov teeb meem ntawm kev nyab xeeb ntawm zaub mov thiab kev tsim khoom ruaj khov thiab kev tsim khoom ntau ntxiv, uas ua rau cov neeg ua liaj ua teb txaus siab rau kev cog qoob loo, yog li txhim kho qhov xav tau ntawm cov khoom ua liaj ua teb xws li chiv phosphating. Tsis tas li ntawd, qhov nce ntawm cov chiv tshiab thiab kev tiv thaiv ib puag ncig tshiab chiv raws li cov chiv tso tawm qeeb qeeb, chiv nitro compound, chiv yaj hauv dej, chiv microbial thiab chiv pob, thiab lwm yam, kuj tau txhawb kev loj hlob ntawm kev thov chiv phosphate mus rau qee qhov.
"Thaum Lub Ob Hlis, cov khoom muag nruab nrab ntawm cov tuam txhab cyclopylodium -phosphate yog li ntawm 69,000 tons, nce 118.92% xyoo-rau-xyoo; cov khoom muag nruab nrab ntawm ib lub tuam txhab ammonium -phosphate yog li ntawm 83,800 tons, nce 4.09% xyoo-rau-xyoo." Raws li txoj cai macro tag nrho ntawm lub xeev-muaj-lub xeev-lavanteed tus nqi, nws xav tias yuav muaj kev muab cov chiv caij nplooj ntoos hlav hauv kev lag luam chiv phosphate yuav tsum tau lav.
Cov nqi ruaj khov thiab zoo dua
Tam sim no, kev lag luam rov ua phosphorus yog nyob rau lub caij nplooj ntoo hlav siab tshaj plaws. Lub teb chaws tau tsim ntau txoj cai rau kev ruaj khov ntawm kev muab khoom, thiab tus nqi ntawm cov chiv phosphate yuav rov qab zoo.
"Tus nqi ntawm cov phosphorus ore tau nce siab tas li, tus nqi ntawm cov sulfur nce siab, cov kua ammonia ruaj khov thiab zoo, thiab cov yam ntxwv dav dav txhawb nqa kev txhawb nqa tus nqi chiv phosphate." Qiao Liying hais.
Wang Fuguang tau tshuaj xyuas tias tam sim no cov khoom siv phosphorus ore hauv tsev tsis txaus, cov khoom muag feem ntau tsis txaus, thiab cov lag luam txaus. Feem ntau, vim muaj cov khoom siv phosphate ore ntau, kev muab khoom hauv khw tsis txaus, thiab tus nqi ntawm cov phosphate ore luv luv tseem nyob siab.
Nws nkag siab tias qhov chaw nres nkoj Yangtze River granular daj mainstream muaj 1300 yuan (tus nqi tuj, tib yam hauv qab no), piv rau qhov nce ntawm 30 yuan yav dhau los. Qhov sib txawv ntawm kev ua lag luam phosphate ore zoo, thiab tus nqi raug thawb me ntsis. Tus nqi ntawm 30% phosphate ore tsheb phaj hauv thaj tsam Guizhou yog 980 ~ 1100 yuan, tus nqi ntawm 30% phosphate ore nkoj phaj hauv thaj tsam Hubei yog 1035 ~ 1045 yuan, thiab tus nqi ntawm 30% phosphate ore hauv thaj tsam Yunnan yog 1050 yuan lossis siab dua. Kev kho thiab ua tsis tiav ntawm cov nroj tsuag ammonia hluavtaws tsis tau rov qab zoo tag nrho, thiab kev muab khoom lag luam tseem nruj, uas ua rau tus nqi ntawm ammonia hluavtaws raug tsa dua, los ntawm 50 ~ 100 yuan hauv nruab nrab thiab sab hnub tuaj Suav teb.
"Cov phosphate ore yog ib qho chaw khaws cia tseem ceeb, txwv los ntawm kev nyab xeeb, kev tiv thaiv ib puag ncig thiab lwm yam, cuam tshuam rau kev khawb av ntawm cov mines, ua rau nws tus nqi muaj zog heev. Thiab sulfur xav tau ntau cov khoom xa tuaj, tsis ntev los no sulfur, sulfuric acid nqi kuj nce siab, yuav luag nce tus nqi tsim khoom ntawm phosphate chiv. Kuv xav tias tus nqi ntawm phosphorus chiv yuav ruaj khov thaum lub caij nplooj ntoos hlav plowing, tab sis kuj muaj qhov ua tau ntawm qhov me me upside. "Zhao Chengyun hais.
Tam sim no, cov khoom siv raw ntawm monoammonium phosphate tseem nce ntxiv, kev txhawb nqa zoo tau txhim kho, Hubei 55% hmoov monoammonium phosphate lub Hoobkas hais txog 3200 ~ 3350 yuan, kev xav yuav cov chiv av hauv qab tau rov zoo, kev ua lag luam yav tom ntej xav tias yuav nce cov neeg muag khoom yuav, kev ua lag luam monoammonium phosphate kuj tseem yuav kub; Kev xav ntawm kev ua lag luam ntawm diammonium phosphate tau zoo dua, Hubei cheeb tsam 64% ntawm lub Hoobkas hais txog diammonium phosphate txog 3800 yuan, kev ua lag luam kom nrawm dua, cov tub luam hauv qab tos-thiab-saib kev xav me ntsis tsis muaj zog.
Tsis txhob muaj kev yuav khoom hauv nruab nrab
Cov neeg ua lag luam hauv kev lag luam ntseeg tias, txawm hais tias lub caij nplooj ntoos hlav ua liaj ua teb xyoo no lub sijhawm qeeb li 20 hnub, tab sis nrog kev tuaj txog ntawm kev thov khov kho, cov nqi chiv phosphate tseem yuav ruaj khov thiab me me, cov neeg muag khoom yuav tsum yuav ua ntej kom tsis txhob muaj kev yuav khoom hauv nruab nrab los ntawm kev pheej hmoo ntawm kev nce nqi.
"Feem ntau, kev ua lag luam phosphate chiv tam sim no tsis ruaj khov, tus nqi luv luv yuav ruaj khov. Nyob rau hauv lub sijhawm ntev, peb yuav tsum tau them sai sai rau kev hloov pauv ntawm cov khoom siv raw, kev thov ua liaj ua teb caij nplooj ntoos hlav, thiab cov cai xa tawm." Joli Ying hais.
"Txais tau txiaj ntsig los ntawm kev tsim kho sai ntawm cov tsheb fais fab tshiab, qhov kev thov rau cov roj teeb lithium hlau phosphate muaj zog heev, tsav tsheb qhov kev thov rau phosphate, txoj kev ntub dej los ntxuav phosphate, thiab phosphate kev lag luam. Nws khiav nrog qhov xwm txheej ruaj khov. "Wang Ying tau hais tias kev lag luam chiv phosphate yuav tsum ntsib nrog tus nqi tsim nyog, them sai sai rau qhov cuam tshuam ntawm kev puas tsuaj huab cua rau kev ua liaj ua teb thiab kev nthuav dav ntawm thaj chaw cog qoob loo, thiab ua kev tshawb fawb thiab kev txiav txim siab hauv kev hloov pauv ntawm ntau yam cuam tshuam, zam kev pheej hmoo, paub txog kev lag luam, paub txog kev lag luam kev ua haujlwm ruaj khov thiab siv zog rau qhov txiaj ntsig siab tshaj plaws.
Wang Fuguang tau hu rau cov tuam txhab ua chiv sib xyaw thiab cov neeg muag khoom ua liaj ua teb kom koom nrog kev ua chiv rau lub caij nplooj ntoo hlav, saib xyuas cov xwm txheej tam sim no ntawm kev ua lag luam, khaws cia kev ua chiv rau lub caij nplooj ntoo hlav thiab siv cov chiv thiab cov chiv rau lub caij ntuj sov. Tus nqi tsis sib npaug.
