Cov ntaub ntawv phaj hlau feem ntau yog cov khoom siv ib txwm muajcov hlau phaj, hlau tsis xeb, hlau ceev ceev, hlau manganese siab thiab lwm yam. Lawv cov khoom siv tseem ceeb yog hlau yaj, uas yog cov khoom siv ua los ntawm cov hlau nchuav tom qab txias thiab tom qab ntawd nias tshuab. Feem ntau ntawm cov phaj hlau yog tiaj tus lossis duab plaub fab, uas tsis tsuas yog tuaj yeem nias tshuab xwb, tab sis kuj txiav nrog cov hlau dav dav.
Yog li ntawd, cov hom hlau phaj yog dab tsi?
Kev faib tawm los ntawm tuab
(1) phaj nyias: tuab <4 hli
(2) Phaj nruab nrab: 4 hli ~ 20 hli
(3) Phaj tuab: 20 hli ~ 60 hli
(4) Phaj tuab heev: 60 hli ~ 115 hli
Faib raws li txoj kev tsim khoom
(1)Cov hlau kub dov phaj: Qhov saum npoo ntawm cov txheej txheem kub khi muaj daim tawv nqaij oxide, thiab lub phaj tuab muaj qhov sib txawv qis dua. Cov phaj hlau kub dov muaj qhov nyuaj tsawg, yooj yim ua thiab ductility zoo.
(2)Cov phaj hlau txias: tsis muaj daim tawv nqaij oxide ntawm qhov chaw ntawm kev ua cov txheej txheem txias, zoo. Lub phaj txias-dov muaj qhov nyuaj siab thiab ua cov txheej txheem nyuaj, tab sis nws tsis yooj yim rau deform thiab muaj lub zog siab.
Faib tawm los ntawm cov yam ntxwv ntawm qhov chaw
(1)Cov ntawv galvanized(daim ntawv galvanized kub, Daim ntawv Electro-galvanized): Txhawm rau tiv thaiv qhov chaw ntawm daim hlau phaj kom tsis txhob xeb kom ntev nws lub neej kev pabcuam, qhov chaw ntawm daim hlau phaj yog coated nrog ib txheej ntawm cov hlau zinc.
Kub dip galvanizing: cov hlau nyias nyias raug muab tso rau hauv lub tank zinc yaj, kom nws qhov chaw lo rau ib txheej ntawm zinc hlau nyias nyias. Tam sim no, nws feem ntau yog tsim los ntawm kev txuas ntxiv galvanizing txheej txheem, uas yog, txuas ntxiv immersion ntawm cov hlau dov hauv cov tank zinc plating yaj kom ua cov hlau galvanized.
Daim ntawv electro-galvanized: Cov hlau galvanized ua los ntawm electroplating muaj kev ua haujlwm zoo. Txawm li cas los xij, cov txheej txheej nyias thiab qhov tiv taus corrosion tsis zoo li cov ntawv kub-dip galvanized.
(2) Cov hlau nplaum
(3) Cov hlau sib xyaw ua ke
(4)Xim coated steel phaj: feem ntau hu ua xim hlau phaj, nrog rau cov hlau txias-kuav los yog kub-dip galvanized hlau phaj lossis aluminized zinc hlau phaj ua lub substrate, tom qab degreasing nto, phosphating, chromate kho thiab hloov pauv, coated nrog organic txheej tom qab ci.
Nws muaj cov yam ntxwv ntawm lub teeb yuag, lub zog siab, xim ci thiab lub zog zoo. Siv dav hauv kev tsim kho, khoom siv hauv tsev, kho kom zoo nkauj, tsheb thiab lwm yam teb.
Kev faib tawm los ntawm kev siv
(1) Choj hlau phaj
(2) Boiler steel phaj: siv dav hauv roj av, tshuaj lom neeg, chaw tsim hluav taws xob, boiler thiab lwm yam lag luam.
(3) Cov hlau ua nkoj: cov hlau nyias thiab cov hlau tuab uas tsim los ntawm cov hlau tshwj xeeb rau kev tsim cov qauv nkoj ntawm cov nkoj mus rau hauv dej hiav txwv, ntug dej hiav txwv thiab hauv av.
(4) Phaj hlau tiv thaiv
(5) Phaj hlau tsheb:
(6) Lub ru tsev hlau phaj
(7) Cov hlau phaj:
(8) Phaj hlau hluav taws xob (silicon steel sheet)
(9) Lwm tus
Peb muaj ntau tshaj 17 xyoo ntawm kev nplua nuj nyob rau hauv daim teb ntawm hlau, peb cov neeg siv khoom nyob rau hauv Suav teb thiab ntau tshaj 30 lub teb chaws thiab cheeb tsam thoob plaws ntiaj teb, suav nrog Tebchaws Meskas, Canada, Australia, Malaysia, Philippines thiab lwm lub teb chaws, peb lub hom phiaj yog los muab cov khoom lag luam hlau zoo rau cov neeg siv khoom thoob ntiaj teb.
Peb muab cov nqi khoom sib tw tshaj plaws kom ntseeg tau tias peb cov khoom zoo ib yam raws li cov nqi zoo tshaj plaws, peb kuj muab cov neeg siv khoom nrog kev lag luam ua tiav tob. Rau feem ntau cov lus nug thiab cov lus hais, tsuav yog koj muab cov lus qhia ntxaws ntxaws thiab cov kev xav tau ntau npaum li cas, peb yuav teb koj hauv ib hnub ua haujlwm.
