Ua ntej, qhov kev thov rau qhov ncauj qhov ntswg tau nce, thiab tus nqi ntawmdaim ntaub meltblowntau nce sai, los ntawm 18,000 yuan / ton ua ntej muaj kev sib kis mus rau 200,000 yuan / ton thaum kawg ntawm Lub Ob Hlis, thiab ob npaug ntxiv rau 520,000 yuan / ton thaum lub Peb Hlis ntxov, tus nqi nce 29-fold.Tsuas yog dhau ib lub lis piam tom qab, raws li Lub Sijhawm Kev Ruaj Ntseg, tus nqi ntawm cov ntaub meltblown tau poob rau qee qhov tsis ntev los no.
Ib tus neeg sab hauv kev lag luam tau hais rau Securities Times tus neeg sau xov xwm: Qhov sib txawv ntawm cov khoom lag luam txawv txav thiab nce siab tau raug txwv, tab sis tag nrho cov xwm txheej ntawm cov khoom siv nruj ntawm cov ntaub ntawv meltblown tsis tau txo qis.
Nws tau nkag siab tias cov khoom siv raw polypropylene yav tom ntej tus nqi ntawm cov ntaub meltblown hloov pauv nrog cov nqi roj, uas muaj kev cuam tshuam me ntsis.Qhov laj thawj ntawm tus nqi nce siab yog vim qhov tsis txaus ntseeg loj ntawm cov khoom siv thiab kev thov ntawm cov ntaub meltblown, kev sib tw ntawm cov lag luam hauv qab thiab cov tib neeg, thiab cov superposition ntawm qee cov tswv lag luam los txhawb thiab lwm yam., ua rau tus nqi tsev soar.Thaum muaj kev sib kis, ntau lub lag luam hauv qab ntawm lub npog ntsej muag raug tshem tawm vim tsis txaus ntawm daim ntaub meltblown.
Qee lub koom haum tshawb fawb tau xav li ntawd.Tam sim no, txoj hauv kev tseem ceeb ntawm kev nthuav dav ntau lawm hauv ntu nruab nrab suav nrog: cov tuam txhab tsim khoom qub nce peev txheej ntau lawm los ntawm kev tshawb fawb thiab kev tsim kho tshuab, khoom siv hloov pauv, thiab lwm yam .;qee qhov kev lag luam petrochemical tau pib tsim cov kab ntau lawm;cov tuam txhab uas muaj cov kab kev lag luam zoo sib xws kho cov kab ntau lawm kom yooj yim rau cov khoom siv raw.
Piv txwv li, Dalian Ruiguang Nonwovens Group Co., Ltd. tau nce nws lub peev xwm ntau lawm los ntawm 4-5 tons thaum nws tau muab tso rau hauv kev tsim khoom thaum Lub Ib Hlis 28 txog 80,000-100,000 tons los ntawm kev tshawb fawb theem nrab thiab kev loj hlob ntawm cov thev naus laus zis tseem ceeb thiab cov txheej txheem optimization.
Upstream petrochemical tuam txhab uas muag, sawv cev los ntawm Sinopec, tau pib tsim cov kab ntau lawm.Tam sim no, cov khoom lag luam tau raug muag thiab tawm hauv lub Hoobkas: Sinopec pawg tog tau txiav txim siab nqis peev txog 200 lab yuan nyob rau hauv qhov xwm txheej tam sim no ntawm kev tiv thaiv thiab tswj kev kis mob hnyav thoob plaws lub tebchaws thiab tsis txaus cov khoom siv raw rau lub qhov ncauj qhov ntswg.Nrog nws tus kheej cov khoom siv raw khoom zoo, nws tam sim ntawd npaj cov khoom muag, thiab sai sai ua 10 meltblown daim ntaub ntau lawm kab nyob rau hauv ob lub tuam txhab, Beijing Yanshan Petrochemical thiab Jiangsu Yizheng Chemical Fiber.
Thaum Lub Peb Hlis 9, Sinopec Yanshan Petrochemical txoj kab tshiab meltblown cov kab ntau lawm tau ua tiav thiab muab tso rau hauv kev ua haujlwm.Thawj pawg ntawm cov khoom muag thiab tawm hauv lub Hoobkas, nrog rau tag nrho ntawm 35 lub thawv ntawm 1.26 tons ntawm meltblown daim ntaub, txhawm rau txo lub tuam txhab qhov tsis txaus ntawm daim npog ntsej muag raw khoom.
Nws yog to taub hais tias txhua xyoo tsim tsim muaj peev xwm ntawm cov yaj-blown non-woven npuag ntau lawm kab muab tso rau hauv lub lag luam los ntawm Yanshan Petrochemical yog 14,400 tons, nrog rau ob lub melt-blown non-woven npuag ntau lawm kab thiab peb spunbond ntaub ntau lawm kab, uas muaj peev xwm. tsim 4 tons ntawm N95 yaj-blown ntaub los yog 6 tons ib hnub twg.Meltblown daim ntaub rau kev kho mob tiaj tus daim npog qhov ncauj.Cov ntaub ntawv nyoos no tuaj yeem tsim tau 1.2 lab daim (4 tons × 300,000 daim / tuj) ntawm N95 lub qhov ncauj qhov ntswg, lossis 6 lab daim (6 tons × 1 lab daim / ton) ntawm lub qhov ncauj qhov ntswg.
Tsis tas li ntawd, cov tuam txhab uas tsim cov tsheb suab rwb thaiv tsev paj rwb, melt-blown thermal rwb thaiv tsev paj rwb, yaj-blown roj-absorbing paj rwb thiab lwm yam ntaub ntawv tuaj yeem hloov mus rau cov khoom siv lim tshwj xeeb rau kev tiv thaiv lub ntsej muag.
Los ntawm qhov kev xav tam sim no, kev nthuav dav ntawm kev tsim khoom hauv ntu nruab nrab tau ua rau lub zog ntawm kev tsim tawm, yog li tus nqi ntawm cov ntaub meltblown tau pib poob.
