Ntau tshaj li ib nrab ntawm lub Kaum Ob Hlis tau ua, kev lag luam hauv tsev monoammonium phosphate tseem tswj kev ua haujlwm tsis muaj zog, tag nrho cov kev xav tau tseem tsis muaj zog, qhov kev txiav txim tshiab tsis txaus los ua raws li, cov lus txiav txim yuav raug xa mus txuas ntxiv, kev muag khoom siab ntawm qee qhov. factories maj mam nce, tus nqi yog tsaus nti kom tau txais kev txiav txim tshiab, kev lag luam tsom tau maj mam txav mus, Central Tuam Tshoj 55 hmoov Hoobkas ze 3350 yuan / tuj, 58 hmoov Hoobkas 3600-3650 yuan / tuj nyob ze, lub Hoobkas tsis muaj tshiab nqe, txuas ntxiv mus ua raws li kev txiav txim ua ntej tau txais. Kev poob qis tuaj yeem kav ntev npaum li cas? Kev ua lag luam tseem tos thiab pom.

Upstream raw khoom:

Phosphate pob zeb: Tsis ntev los no, phosphate pob zeb lag luam tseem siab thiab ruaj khov, thiab tus nqi tseem ceeb ntawm 30% qib phosphate pob zeb hauv Guizhou cheeb tsam yog hais txog 980-1050 yuan / tuj, thiab cov nqi lag luam yog concentrated nyob ib ncig ntawm 1000 yuan / tuj; Tus nqi ntawm 28% qib nkoj phaj hauv Yichang cheeb tsam ntawm Hubei Xeev yog ze 1000 yuan / tuj, thiab tus nqi pauv ntawm 25% qib siab magnesium nkoj phaj yog siab dua 850 yuan / tuj; Sichuan Mabian cheeb tsam 25% qib phosphate pob zeb county tus me nyuam tus nqi siv 650-750 yuan / tuj los yog li ntawd. Tus nqi ntawm 28% qib tsheb phaj hauv Yunnan yog li 850-950 yuan / tuj. Downstream factories yeej lees txais tus nqi tshiab, kev hloov kho tus nqi yav dhau los yog qhov pib siv, thiab cov khoom siv raw khoom tam sim no ntawm phosphate fertilizer tuam txhab lag luam yog ntau tshaj ib hlis.

Sulfur: Raws li lub Kaum Ob Hlis 15, Tuam Tshoj qhov chaw nres nkoj cov khoom muag ntawm leej faj 2,662,500 tons, Yangtze River hais tus kheej tus nqi ntawm 925 yuan / ton. Tsis ntev los no Teb Chaws Asmeskas kev txiav txim siab kom tswj hwm qhov tsis muaj zog tag nrho, Puguang Wanzhou tus nqi qis qis, lub chaw tsim khoom ua ntej thiab tom qab ob qhov kev sib tw muag khoom sib txawv, kev ceev faj tus cwj pwm ntawm cov tub lag luam tsis tau ploj mus, thiab tus neeg muag khoom lub tswv yim txawv, kev ua lag luam me ntsis hloov pauv.

Synthetic ammonia: kev lag luam ammonia tsis ntev los no hauv thaj chaw tsim khoom tseem ceeb yog sib xyaw, huab cua ntawm cov khoom siv thiab kev thov tseem yog dav dav, Shandong kev ua lag luam tau rov qab mus rau qhov muaj txiaj ntsig tom qab nce siab, cov khoom siv thiab kev thov siab hauv nruab nrab Tuam Tshoj thiab Tuam Tshoj sab hnub tuaj tseem yog nyob ntawd, qhov xwm txheej ntawm cov khoom lag luam muaj ntau, kev lag luam chiv yog qhov dav dav thiab tam sim no txo ​​qis hauv cheeb tsam sab qab teb sab hnub poob yog tus nqi qis rau lub lim tiam no, kev ua lag luam feem ntau txuas nrog kev xa khoom.

Khoom siv sab:

Raws li lub Kaum Ob Hlis 15, kev tsim cov mono-ammonium phosphate yog 230,400 tons, qhov txo qis ntawm 15,200 tons ntawm lub hli dhau los, thiab nce ntawm 43,600 tons xyoo-rau-xyoo (cov khoom saum toj no tsis suav nrog cov khoom tsim tawm ntawm diammonium thiab compound fertilizer ntau lawm kab). Lub lim tiam no, kev lag luam muaj peev xwm siv tau ntawm 59.27%, 0.28% siab dua lub lim tiam dhau los, 4.5 feem pua ​​​​cov ntsiab lus siab dua xyoo tas los, Hubei Zhongfu tau tsim cov khoom; Hubei Fengli ntaus ntawv raug txiav tawm. Tsis ntev los no, ib tug me me ntawm cov khoom siv txiav tsis siv neeg tau rov ua haujlwm li qub, tab sis kuj tseem muaj cov chaw tsim khoom los txo cov kev tsim khoom, qhov kev hloov tag nrho yog me ntsis, xav tias yuav tswj tau qhov nqaim ntawm kev siv peev xwm hauv kev lag luam ammonium phosphate hauv lub sijhawm luv.

Xav tau sab:

Tsis ntev los no, cov khoom siv raw xav tau ntawm cov khoom lag luam hauv qab cov chiv chiv tsis muaj zog los ua raws li, thiab kev xav txog kev yuav khoom tseem tos thiab pom. Vim muaj kev cuam tshuam los ntawm cov daus hauv qee qhov chaw, kev xa khoom ntawm cov chiv chiv tau qeeb me ntsis, tab sis feem ntau cov tuam txhab tau xaj kom tau txais, thiab tag nrho cov khoom ntim ntawm cov khoom siv chiv kev lag luam tseem nce ntxiv. Tam sim no, lub peev xwm siv tus nqi ntawm downstream compound fertilizer kev lag luam yog 47.63%, nce ntawm 1.65% piv rau lub lim tiam dhau los, txawm hais tias pib ntawm cov nroj tsuag tseem nce ntxiv, tab sis feem ntau yog tsim kom muaj nitrogen chiv, kev noj phosphorus yog. txwv tsis pub, thiab feem ntau ntawm cov chaw tsim khoom loj thiab cov chaw ua haujlwm sab qaum teb sab hnub tuaj tau ua tiav qee cov khoom siv raw khoom thaum ntxov ntawm cov khoom lag luam, cov nqi ntawm cov khoom siv tsis ntev los no tsis ruaj khov, qhov kev txaus siab ntawm kev yuav khoom tsis siab. Lub atherosclerosis ntawm tshiab monoammonium phosphate xaj yog qeeb.

Hauv cov ntsiab lus, cov khoom siv raw khoom phosphate pob zeb muab cov nqi nruj yog qhov nyuaj rau kev hloov pauv, sulfur nyob rau hauv phosphate chiv ruaj khov ua haujlwm kom tswj tau qhov nqaim sideways oscillation, ammonia ruaj khov kho, tag nrho cov nqi hloov me ntsis. Txawm hais tias qhov chaw muab khoom ntawm mono-ammonium phosphate tsis tau hloov kho rau lub sijhawm tam sim no, qhov kev xav tau tseem muaj kev ntxhov siab, thiab cov khoom muag siab yuav ua rau poob qis. Qhov kev thov rau cov khoom siv raw ntxiv ntawm cov khoom siv hauv av hauv av tseem muaj nyob, tab sis qhov ua tau zoo ntawm kev rov qab los tsis zoo li. Yog li ntawd, tus nqi txhawb zog tseem nyob ntawd, cov khoom yuav hloov pauv raws li qhov xav tau, thiab xav tias kev lag luam mono-ammonium phosphate yuav nyob twj ywm tsis muaj zog thiab maj mam txav mus rau lub sijhawm luv.
