Cov hlau nplaum xim, tseem hu ua cov hlau nplaum xim, ua lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub thiab kev tsim kho. Lawv siv cov ntawv hlau galvanized kub-dip, cov ntawv hlau txhuas-zinc kub-dip, cov ntawv hlau electro-galvanized, thiab lwm yam ua cov khoom siv, dhau los ntawm kev kho kom zoo nkauj ntawm qhov chaw, suav nrog kev tshem tawm cov roj thiab kev kho hloov pauv tshuaj, thiab tom qab ntawd siv ib lossis ntau txheej ntawm cov txheej txheem organic rau ntawm qhov chaw. Thaum kawg, lawv raug ci thiab kho kom zoo. Vim tias qhov chaw yog coated nrog cov txheej txheem organic ntawm ntau yam xim, cov hlau nplaum xim tau muab npe tom qab lawv, thiab raug xa mus rau cov hlau nplaum xim.
Keeb Kwm Kev Loj Hlob
Cov ntawv hlau xim pleev xim tau pib hauv Tebchaws Meskas thaum nruab nrab xyoo 1930. Thaum xub thawj, lawv yog cov hlau nyias nyias uas pleev xim rau, feem ntau yog siv los ua cov ntaub thaiv qhov muag. Nrog rau kev nthuav dav ntawm qhov ntau thiab tsawg ntawm daim ntawv thov, nrog rau kev txhim kho ntawm kev lag luam pleev xim, cov tshuaj ua ntej kho thiab cov thev naus laus zis kev lag luam automation, thawj chav tsev txheej dav dav tau tsim hauv Tebchaws Meskas xyoo 1955, thiab cov txheej kuj tau tsim los ntawm cov xim alkyd resin thawj zaug mus rau cov hom uas muaj zog tiv taus huab cua thiab cov xim inorganic. Txij li xyoo 1960, cov thev naus laus zis tau nthuav dav mus rau Tebchaws Europe thiab Nyiv Pooj thiab tau tsim kho sai. Keeb kwm kev txhim kho ntawm cov kauj xim pleev xim hauv Suav teb yog li 20 xyoo. Cov kab ntau lawm thawj zaug tau qhia los ntawm Wuhan Iron and Steel Corporation los ntawm David Company hauv UK thaum Lub Kaum Ib Hlis 1987. Nws siv cov txheej txheem ob txheej thiab ob txheej ci thiab cov txheej txheem txheej txheej tshuaj ua ntej, nrog rau lub peev xwm tsim khoom txhua xyoo ntawm 6.4 tons. Tom qab ntawd, Baosteel cov khoom siv xim txheej tau muab tso rau hauv kev tsim khoom hauv xyoo 1988, qhia los ntawm Wean United hauv Tebchaws Meskas, nrog rau qhov ceev tshaj plaws ntawm 146 meters ib feeb thiab tsim kom muaj peev xwm tsim khoom txhua xyoo ntawm 22 tons. Txij thaum ntawd los, cov chaw tsim khoom hlau loj hauv tsev thiab cov chaw tsim khoom ntiag tug tau mob siab rau kev tsim cov kab ntau lawm xim-coated. Kev lag luam xim-coated coil tau tsim kho sai thiab tam sim no tau tsim ib txoj saw hlau kev lag luam tiav thiab tiav.
