Thaum xyoo 1980s, Tuam Tshoj pib tsim cov xim txheej ua tiav.Feem ntau ntawm cov chav tsev no tau tsim nyob rau hauv cov hlau thiab steel nroj tsuag thiab kev sib koom ua lag luam, thiab cov txheej txheem xim txheej txheej txheem tau pib los ntawm txawv teb chaws.Los ntawm 2005, lub domestic xim coated board tau mus txog 1.73 lab tons, ua rau overcapacity.Baosteel, Anshan Hlau thiab hlau, Benxi Hlau thiab hlau, Shougang, Tangshan Hlau thiab hlau, Jinan Hlau thiab hlau, Kunming Hlau thiab hlau, Handan Hlau thiab hlau, Wuhan Hlau thiab hlau, Panzhihua Hlau thiab hlau thiab lwm yam loj lub xeev cov hlau thiab steel tuam txhab muaj peev xwm thiab cov cuab yeej siv siab.Lawv tau ua tiav cov xim txheej txheej nrog txawv teb chaws technology thiab txhua xyoo muaj peev xwm ntawm 120000 ~ 170000 tons.
Nyob rau tib lub sijhawm, kev tsim cov xim coated boards nqis peev los ntawm ntau lub tuam txhab ntiag tug feem ntau siv cov cuab yeej siv hauv tsev, nrog cov peev txheej me me, tab sis nws tau nrawm rau kev tsim tawm thiab kev nqis peev tsawg.Cov khoom yog tsuas yog rau cov khoom siv hauv tsev thiab kho kom zoo nkauj kev lag luam.Tsis tas li ntawd, cov peev txawv teb chaws thiab Taiwan lub peev kuj tau tsaws los tsim cov xim txheej, tab sis lawv feem ntau yog tsom rau thaj chaw ntug dej hiav txwv.Txij li thaum xyoo 1999, nrog kev vam meej ntawm cov xim coated phaj lag luam, kev tsim khoom thiab kev siv cov xim coated phaj tau nkag mus rau lub sijhawm ntawm kev loj hlob sai.Los ntawm 2000 mus rau 2004, qhov ntau lawm tau nce ntawm tus nqi nruab nrab ntawm 39.0%.Los ntawm 2005, lub teb chaws muaj peev xwm ntawm cov xim coated daim hlau yog ntau tshaj 8 lab tons / xyoo, thiab ib tug xov tooj ntawm cov xim coated units twb nyob rau hauv kev tsim kho, nrog rau tag nrho lub teb chaws muaj peev xwm ntau tshaj 9 lab tons / xyoo.
Cov teeb meem uas twb muaj lawm: 1 Txawm hais tias lub peev xwm ntawm kub-dip galvanized puag phaj rau lub tsev cov ntaub ntawv yog loj, muaj ib tug tsis muaj zoo puag daim hlau xws li ca kub-dip galvanized steel kauj tsis muaj zinc paj thiab zinc alloy coated steel kauj;2. Qhov ntau thiab zoo ntawm cov txheej hauv tsev tsis tuaj yeem ua tau raws li qhov xav tau.Tus nqi siab ntawm cov txheej txheem tuaj yeem txo qhov kev sib tw.Cov yeeb yaj kiab yas uas yuav tsum tau ua rau cov xim xim phaj tseem yuav tsum tau tuaj txawv teb chaws, thiab tsis muaj cov xim qib siab nrog cov txheej tuab, kev ua haujlwm siab, siab zog thiab nplua nuj xim;3. Cov khoom tsis yog tus qauv, ua rau muaj kev puas tsuaj loj.Muaj ntau lub zog qis qis uas muaj peev xwm tsawg dua 40000 tons / xyoo, thiab muaj teeb meem ntawm cov khoom zoo thiab kev tiv thaiv ib puag ncig;4. Muaj ntau ntau cov xim txheej txheej tshiab hauv Suav teb, uas deb tshaj qhov kev xav tau ntawm kev ua lag luam, ua rau qis kev khiav hauj lwm ntawm ntau cov xim txheej thiab txawm tias kaw.
Txoj kev loj hlob:
Ua ntej, kev siv cov substrate zoo yuav tsum tau ua kom siab dua thiab siab dua rau saum npoo, cov duab thiab qhov tseeb ntawm lub substrate.Rau kev siv sab nraum zoov, xws li me me zinc paj tiaj tus kub-dip galvanized steel kauj thiab tsis yog zinc paj tiaj tus kub-dip galvanized steel kauj, zinc alloy kub-dip galvanized kauj nce hauv lub sijhawm;Rau kev siv sab hauv tsev, xws li galvanized steel kauj, coated txias-kuav los tiag ntawv thiab txhuas coil.
Thib ob, txhim kho cov txheej txheem pretreatment thiab ua kua ua ntej.Nrog cov cuab yeej siv tsawg thiab tus nqi qis, nws tau dhau los ua cov txheej txheem tseem ceeb, thiab niaj hnub txhim kho kev ruaj ntseg, kev tiv thaiv corrosion thiab kev tiv thaiv ib puag ncig ntawm cov kua pretreatment.
Thib peb, kev txhim kho cov txheej txheem tshiab yog txhawm rau txhim kho cov txheej txheem polyester, polyvinylidene fluoride (PVDF) thiab yas sol kom tau txais cov xim zoo dua qub, UV tsis kam, sulfur dioxide kuj thiab corrosion kuj;Tsim cov txheej txheem ua haujlwm xws li kev ua pa phem thiab nqus cua sov.
Plaub, cov khoom siv hauv chav tsev zoo meej dua.Piv txwv li, cov tshuab vuam tshiab, cov tshuab tshiab yob txheej, txhim kho qhov cub kom zoo dua qub, thiab cov cuab yeej siv tsis siv neeg siab heev yog siv.
Thib tsib, lub tshuab txias embossing ntau lawm tau dhau los ua ib qho kev txhim kho vim nws cov nqi qis, zoo nkauj tsos, peb-dimensional xav thiab siab zog.
Thib rau, xyuam xim rau kev sib txawv, kev ua haujlwm thiab qib siab ntawm cov khoom, xws li sib sib zog nqus xim xim txheej board, "grapefruit skin" xim txheej board, anti-static xim txheej board, muaj kuab paug-resistant xim txheej board, siab kub nqus xim txheej board, thiab lwm yam.
Cov qauv tam sim no nyob rau hauv Suav teb yog cov xim coated phaj manufacturers them ntau thiab ntau xim rau qhov zoo ntawm substrates siv nyob rau hauv lawv tus kheej zus tau tej cov xim coated daim hlau, thiab muaj ntau dua thiab ntau dua yuav tsum tau rau lawv tus kheej ntau lawm txheej txheem, uas ua rau cov xim coated daim hlau muaj. ib qho zoo heev pab txhawb rau kev tsim khoom.Tsis tas li ntawd, cov khoom siv rau kev tsim cov xim coated daim hlau kuj tseem ua tau zoo heev, uas ua rau cov xim coated daim hlau ntau dua thiab ntau dua automated hauv kev tsim khoom, uas tsis tsuas yog txuag tus nqi, tab sis kuj txuag tau ntau tus neeg ua haujlwm, Tsis tas li ntawd, muaj ntau thiab ntau. ntau xim coated phaj manufacturers, thiab kev ua lag luam kev sib tw yog ua ntau thiab hnyav.Kev txhim kho cov khoom zoo thiab txo cov nqi tsim khoom tau pib ua qhov kev coj ua ntawm cov xim coated phaj manufacturers.Xim coated board khoom tau dhau los ua ntau thiab ntau haiv neeg.Cov xim sib txawv coated boards tuaj yeem ua si ntau yam sib txawv, uas ua rau cov xim coated board ua lag luam zoo siab heev.
