Mukupera kwema1980, China yakatanga kuvaka mayuniti ekupfekedza mavara zvakatevedzana.Zvizhinji zvezvikamu izvi zvakavakwa musimbi nesimbi zvidyarwa uye mabhizimusi akabatanidzwa, uye michina yekupfekedza mavara yakatengwa kubva kunze kwenyika.Pakazosvika 2005, bhodhi remukati rakavharwa neruvara rakange rasvika 1.73 miriyoni matani, zvichikonzera kuwandisa.Baosteel, Anshan Iron nesimbi, Benxi Iron nesimbi, Shougang, Tangshan Iron nesimbi, Jinan Iron nesimbi, Kunming Iron nesimbi, Handan Iron nesimbi, Wuhan Iron nesimbi, Panzhihua Iron nesimbi uye mamwe makuru ehurumende simbi. uye mabhizinesi esimbi ane yakakwira unit huwandu uye nhanho yemidziyo.Ivo vakatevedzana vakavaka mapeji ekuputira mavara ane tekinoroji yekune dzimwe nyika uye gore rega rekugadzira kugona kwe120000 ~ 170000 matani.
Panguva imwecheteyo, kugadzirwa kwemavara akavharwa mabhodhi akaiswa mari nemabhizinesi mazhinji akazvimirira anotora midziyo yemumba, ine diki yekugadzira, asi inokurumidza kutanga uye yakaderera mari.Zvigadzirwa zvinonyanya zvekuvaka uye maindasitiri ekushongedza.Uye zvakare, guta rekune dzimwe nyika uye guta reTaiwan rakadzikawo kuti rivake mapeji ekuputira mavara, asi mazhinji acho akaiswa munzvimbo dzemahombekombe.Kubva 1999, nekubudirira kwemusika wakavharwa neplate, kugadzirwa uye kushandiswa kweplate yakavharwa nemavara kwakapinda munguva yekukura nekukurumidza.Kubva 2000 kusvika 2004, kugadzirwa kwakawedzera paavhareji ye 39.0%.Pakazosvika 2005, huwandu hwenyika hwekugadzira mahwendefa akavharwa neruvara hwaive hunopfuura mamirioni masere ematoni / gore, uye akati wandei emavara akafukidzwa mayuniti aive ari kuvakwa, aine huwandu hwenyika hwekugadzira hunopfuura 9 miriyoni matani / gore.
Matambudziko aripo: 1 Kunyangwe kugona kwekugadzira kupisa-dip galvanized base ndiro yezvigadzirwa zvekuvakisa yakakura, pane kushaikwa kwemaplateti akanaka egasi senge flat hot-dip galvanized steel coil isina zinc ruva uye zinc alloy coil coil yesimbi;2. Izvo zvakasiyana-siyana uye hutano hwehuputi hwepamba haigoni kuzadzisa zvinodiwa.Mutengo wakakwirira wezvipfeko zvinotengeswa kunze kwenyika zvinoderedza kukwikwidzana.Firimu repurasitiki rinodiwa kune firimu ruvara ndiro richiri kuda kutengwa kunze kwenyika, uye pane kushomeka kwepamusoro-giredhi ruvara ndiro ine gobvu coating, kushanda, yakakwirira simba uye akapfuma mavara;3. Zvigadzirwa hazvina kumira, zvichiita kuti kupambadza kwakakomba kwezvinhu.Kune akawanda akawandisa emagetsi mashoma ane huwandu husingasviki 40000 matani / gore, uye kune matambudziko mumhando yechigadzirwa uye kuchengetedza zviwanikwa zvezvakatipoteredza;4. Kune akawanda akawandisa mavara matsva ekuputira mayuniti muChina, ayo anodarika zvakanyanya kudiwa kwemusika, zvichikonzera kuderera kwekushanda kwemayuniti akawanda ekupfekedza mavara uye kunyange kudzima.
Development trend:
Kutanga, kushandiswa kwepamusoro-soro substrate kunoda zvakakwirira uye zvepamusoro zvinodiwa zvepamusoro, chimiro uye chiyero chechokwadi che substrate.Zvekushandisa kunze, sediki zingi ruva rakafuratira rinopisa-dhip galvanized simbi coil uye risiri zingi ruva rakafuratira inopisa-dhip galvanized simbi coil, zinc alloy inopisa-dhip galvanized coil inosimuka nenguva;Zvekushandisa mukati, senge galvanized simbi coil, yakavharwa nechando-yakakungurutswa sheet uye aluminium coil.
Chechipiri, vandudza pretreatment process uye pretreatment fluid.Nemidziyo mishoma uye nemutengo wakaderera, yave iyo nzira yemazuva ese, uye inogara ichivandudza kugadzikana, corrosion kuramba uye kuchengetedza kwezvakatipoteredza kuita kweiyo pretreatment fluid.
Chechitatu, kuvandudzwa kwemachira matsva kuvandudza iyo polyester yakawanda, polyvinylidene fluoride (PVDF) uye plastiki sol kuti iwane super color reproducibility, UV kuramba, sulfur dioxide kuramba uye corrosion resistance;Gadzira mabhanhire anoshanda akadai sekudzivirira kusvibiswa uye kutora kupisa.
Chechina, iyo unit midziyo yakanyanya kukwana.Semuyenzaniso, michina mitsva yewelding, michina mitsva yekupfekedza roll, mavira akakwenenzverwa, uye zviridzwa zvemberi otomatiki zvinoshandiswa.
Chechishanu, iyo inotonhora embossing yekugadzira tekinoroji yave nzira yekusimudzira nekuda kwemutengo wayo wakaderera, kutaridzika kwakanaka, kunzwa kwemativi matatu uye simba rakakwirira.
Yechitanhatu, teerera kune kusiyanisa, kushanda uye yakakwirira-giredhi yezvigadzirwa, seyakadzika dhizaini coating board, "grapefruit ganda" coating board bhodhi, anti-static color coating board, kusvibiswa-inodzivirira ruvara coating board, kupisa kwakanyanya kunyudza ruvara. coating board, nezvimwewo.
Maitiro aripo muChina ndeokuti vagadziri veplate rakavharidzirwa vanobhadhara zvakanyanya uye zvakanyanya kutarisisa kumhando ye substrates inoshandiswa mukugadzira kwavo mahwendefa akavharwa neruvara, uye vane zvakakwirira nepamusoro zvinodiwa pakuita kwavo kugadzira, izvo zvinoita kuti mahwendefa akavharidzirwa ave nemavara. mupiro wakaisvonaka kune nzira yekugadzira.Uyezve, michina yekugadzira mahwendefa akavharidzirwa nemavara zvakare yakawedzera, izvo zvinoita kuti mavara akavharwa mahwendefa awedzere uye azere otomatiki mukugadzira, izvo kwete chete kuchengetedza mutengo, asi zvakare inochengetedza akawanda evashandi, Uyezve, kune akawanda uye vagadziri vendiro yemavara akawanda, uye makwikwi emusika ari kuramba achiwedzera.Kuvandudza kunaka kwechigadzirwa uye kudzikisa mutengo wekugadzirwa kwechigadzirwa zvatova tsika yakajairika yevagadziri vendiro yakavharwa nemavara.Ruvara coated board zvigadzirwa zvave zvakanyanya uye zvakasiyana.Akasiyana mavara akavharidzirwa mabhodhi anogona kutamba akawanda akasiyana mabasa, izvo zvinoita kuti musika wakavharwa bhodhi musika unakidze.
