Raws li ntu tseem ceeb ntawm kev lag luam txheej, coil txheej, los ntawm cov lus txhais, yog cov tshuab txheej siv rau saum npoo ntawm cov hlau tiaj tus lossis cov ntawv ua los ntawm cov hlau lossis txhuas uas siv dav hauv ntau qhov kev siv kev lag luam. Cov no suav nrog kev tsim kho, kev tsim kho tsheb, kev tsim khoom siv hauv tsev, thiab ntau lwm qhov chaw muaj.
Coil txheej khoom tsim kho thawj zaug thiab siv hauv Asmeskas hauv xyoo 1930, thaum kev lag luam txheej suav hauv Suav tau pib thaum xyoo 1980s. Tom qab txuas ntxiv txoj kev vam meej ntawm Tuam Tshoj txoj kev lag luam, tshwj xeeb tshaj yog kev tsim kho kev lag luam, kev thov rau cov ntawv ua ntej steel hlau loj hlob sai, yog li tsav kev loj hlob sai ntawm coil txheej ntau lawm hauv 10 xyoo dhau los. Niaj hnub no, Tuam Tshoj cov peev txheej tsim tawm ntawm cov coil txheej tau dhau 400,000 tons, siv ntau dua 50% ntawm Asia cov zis thiab ntau tshaj 30% ntawm cov txiaj ntsig thoob ntiaj teb.
LAG LUAM NYIAM LUB XEEM
Nrog rau kev txhim kho hauv nroog hauv nroog txuas ntxiv mus rau kev nce qib, qhov kev vam meej ntawm kev lag luam vaj tsev coj kev thov loj heev rau kev tsim kho cov ntaub ntawv, uas yog daim teb thov tseem ceeb rau cov ntawv ua ntej hlau cov ntawv. Lub sijhawm xyoo 2007 txog 2017, tag nrho cov khoom siv ntawm cov tsho tiv no hauv Suav tau nce ntawm 152,000 tons txog 507,000 tons, nrog CAGR li ntawm 13.5%. Cov khoom lag luam tsim tawm tau txog 8,62 billion RMB.
Nyob rau xyoo 2015, cuam tshuam los ntawm kev poob qis ntawm kev tsim kho kev lag luam thiab kev tsim peev txheej txo txoj cai hauv kev lag luam steel, qhov ntim ntau lawm ntawm cov coil txheej qis dua 8.4% piv nrog 2014.
Feem ntau ntawm Tuam Tshoj cov yeeb yaj kiab txheej txheej txheem yog ua lag luam nyob rau hauv kev tsim kho kev lag luam, thaum cov tuam txhab thoob ntiaj teb xws li Nippon Paints, Valspar thiab Becker Industrial tus thawj cov khoom lag luam hauv tsev. Qee tus neeg tsim khoom hauv Suav teb loj xws li Shanghai Zhenhua kuj tau pib muab cov tsho tiv no rau cov ua khoom siv hauv tsev.
TSWV YIM KWV TXHIAJ
Feem ntau cov tsho tiv no tuaj yeem muab faib ua cov qauv, cov thim qaum (tseem hu ua thim rov qab) thiab cov tsho saum toj los ntawm cov xim txheej. Lub rooj qhia cov qauv tseem ceeb ntawm cov khoom siv rau txhua txheej txheej.
Rau cov ntawv luam tawm thawj, epoxy-hom thiab polyurethane-hom yog ob qho tib si feem ntau siv
Txog kev txhawb nqa lub tsho tiv no, polyurethane-hom ua cov feem ntau, nrog cov seem me ntawm epoxy-hom thiab lwm tus
Rau cov topcoats, polyester-hom feem ntau siv, tuav txog 60% feem pua ntawm kev ua lag luam, tom qab ntawd los ntawm polyurethane, PVDF thiab plastisol
DAIM NTAWV THOV
Pre-coated hlau siv nyob rau hauv ntau hom khoom. Nws tuaj yeem tsim rau ntau daim ntawv thov sib txawv, suav nrog lub tsev tsim vaj tsev, hlau vov tsev, phab ntsa vaj huam sib luag, khoom siv hauv tsev, qhov rooj hauv tsheb, chaw tsim tsheb thiab qhov chaw, rooj tog chaw ua haujlwm, HVAC, khoom noj khoom haus thiab tins ua noj, thiab cov kaus poom haus. Cov kab ntawv tseem niaj hnub loj hlob ntxiv, nrog cov kev lag luam tshiab ua qhov hloov ntawm kev hloov ua tom qab rau cov txheej txheem pleev xim ua ntej txhua xyoo.
Raws li daim ntawv tshaj tawm kev lag luam tshiab los ntawm Hua Aluminium Group, kev tsim kho yog lub khw lag luam loj tshaj plaws rau cov coil txheej thoob ntiaj teb, suav txog kwv yees li 76% feem, thiab yuav yog cov lag luam tseem ceeb tshaj plaws los txhawb txoj kev loj hlob ntawm lub ntiaj teb coil txheej lag luam. Txog ntawm Suav ua lag luam, feem sib koom ua lag luam tsim ua yuav kwv yees li 80% - 90%. Vim tias tsoomfwv Suav tau nqis peev ntau rau kev tsim kho thiab txoj haujlwm "One Belt and One Road" rau yav tom ntej, kev tsim kho tseem yuav yog qhov kev thov tseem ceeb rau lub tsho tiv no.
Kev tsim kho cov khoom siv hauv tsev yog lwm txoj kev lag luam loj loj rau cov coil txheej. Ntau thiab ntau dua Suav teb cov khoom siv hauv tsev tig mus rau kev siv cov txheej txheem ua ntej hlau, thawb qhov nce ntawm kev thov rau cov khoom siv-siv kauj xim txheej.
YOOJ YIM HAIS
Hauv 13th xyoo Kev Npaj Ua Haujlwm ntawm txheej kev lag luam txheej, tag nrho cov kev ua lag luam tawm kwv yees kwv yees mus txog 22 lab tons los ntawm xyoo 2020, nrog CAGR ntawm 5%. Yog tias suav los ntawm kev sib koom ntawm cov coil txheej hauv tag nrho cov kev lo yog xyoo 2015, kwv yees li 2.5%, lub coil txheej ntim yuav yog 550,000 tons los ntawm 2020.
Kev tiv thaiv ib puag ncig lub tsho tiv no, ua kom muaj txheej xim, thiab ntau dua qib coil txheej yuav tau txais ntau xim thiab txhim kho, suav nrog:
Ib puag ncig tus phooj ywg lub tsho tiv no zoo li dej yoj txheej, hmoov txheej txheej, cov ntsiab lus siab, UV-kho txheej txheej
Cov tshuaj fluorocarbon, muaj ntau yam ruaj khov (HDP), silicone hloov kho polyester (SMP) coil txheej
Muaj nuj nqi coil, nrog rau kev ua kom tus kheej tu tsev, pleev xim txias xim lub ru tsev, txheej pleev xim rau kev ua haujlwm thiab cov kab mob tua kab mob.
Hniav tiav xim thiab tsis-hnyav-hlau luam tawm
Cov qib siab sib tshooj coil rau cov khoom siv hauv tsev thiab ntsuab HDP coil txheej rau kev tsim kho
Ntxiv rau ntau dua thiab ntau dua kev siv nyob rau hauv kev tsim kho, khoom siv hauv tsev thiab kev lag luam tsheb, coil txheej yuav tseem siv nyob rau lwm qhov chaw muaj.
