Galvanized ntawv yog hais txog ib daim hlau tuab nrog ib txheej ntawm zinc plated rau saum npoo.Kub-dip galvanizing yog ib qho kev lag luam thiab tsim nyog los tiv thaiv xeb txoj kev uas feem ntau xaiv.Kwv yees li ib nrab ntawm lub ntiaj teb zinc ntau lawm yog siv rau hauv cov txheej txheem no.
Galvanized daim ntawv yog kom tsis txhob muaj corrosion nyob rau saum npoo ntawm daim hlau tuab thiab ua rau nws cov kev pab cuam lub neej.Qhov saum npoo ntawm cov phaj tuab yog coated nrog ib txheej ntawm hlau zinc.Hom zinc-coated tuab steel phaj yog hu ua galvanized ntawv.
Raws li kev tsim khoom thiab kev ua haujlwm, nws tuaj yeem muab faib ua pawg hauv qab no:
① Kub-dip galvanized tuab steel phaj.Cov ntawv txias-dov steel yog infiltrated rau hauv lub molten zinc da dej, yog li ntawd cov saum npoo ntawm cov ntawv txias-dov hlau yog adhered nrog ib txheej ntawm zinc.Nyob rau theem no, tus yuam sij yog siv cov txheej txheem kub-dip galvanizing tas mus li rau kev tsim khoom, uas yog, cov phaj tuab tuab hauv lub phaj yog txuas ntxiv rau hauv lub tank plating nrog molten zinc los ua ib daim ntawv galvanized;
② Fine-grain reinforced galvanized ntawv.Cov phaj tuab no kuj yog tsim los ntawm txoj kev kub dip, tab sis tam sim ntawd tom qab nws tawm ntawm lub tank, nws yog rhuab mus txog 500 ° C los hloov nws mus rau hauv ib qho txhuas alloy yas zaj duab xis ntawm zinc thiab hlau.Hom ntawv galvanized no tau zoo heev adhesion ntawm architectural coatings thiab hluav taws xob vuam;
③ Electro-galvanized ntawv.Kev tsim cov ntawv no galvanized los ntawm electroplating muaj cov txheej txheem zoo heev.Txawm li cas los xij, cov txheej txheej yog nyias, thiab qhov kev tiv thaiv corrosion tsis zoo li cov ntawv kub-dip galvanized;
④ Ib sab thiab ob sab galvanized ntawv.Ib leeg thiab ob sab galvanized ntawv, uas yog, cov khoom uas yog kub-dip galvanized ntawm ib sab.Nyob rau hauv cov nqe lus ntawm hluav taws xob welding, txau, anti-xeb kho, ntau lawm thiab ua, thiab lwm yam, nws muaj zog adaptability tshaj ob-sided galvanized ntawv.Txhawm rau kom tshem tawm qhov tsis xws luag ntawm cov zinc tsis muaj coated ntawm ob sab, muaj lwm hom galvanized ntawv coated nrog chromatographic zinc nyob rau sab nraud, uas yog, galvanized ntawv nrog qhov sib txawv ntawm ob sab;
⑤ Aluminium alloy, composite galvanized ntawv.Nws yog ua los ntawm zinc thiab lwm yam ntaub ntawv hlau xws li txhuas, txhuas, zinc, thiab lwm yam los ua aluminium alloys los yog composite tuab steel daim hlau.Hom tuab steel phaj no muaj ob qho tib si tshwj xeeb los tiv thaiv xeb cov yam ntxwv thiab cov yam ntxwv zoo heev txau;
Ntxiv rau cov saum toj no tsib, kuj muaj cov yeeb yuj galvanized ntawv, tsoos tsho luam ntawv txau galvanized ntawv, polyethylene laminated galvanized ntawv thiab lwm yam.Tab sis nyob rau theem no, feem ntau yog tseem kub-dip galvanized ntawv.
Stainless hlau phaj yog lub npe dav ntawm stainless acid-resistant steel, resistant rau tsis muaj zog corrosion tshuaj xws li roj, chav, dej, los yog steel qib nrog stainless hlau zog yog hu ua stainless hlau phaj;Thaum cov tshuaj hnyav-resistant (acid, alkali, ntsev thiab lwm yam organic tshuaj corrosion) etched steel qib hu ua acid-resistant steels.
Vim tias qhov sib txawv ntawm qhov sib xyaw ntawm ob, lawv cov kev tiv thaiv corrosion yog txawv.Feem ntau, stainless hlau daim hlau feem ntau tsis tiv taus hnyav corrosion, thaum acid-resistant steels feem ntau muaj stainless hlau khoom.Lub sij hawm "stainless steel phaj" tsis tsuas yog hais txog ib hom stainless hlau phaj, tab sis kuj qhia ntau tshaj 100 hom ntawm industrially ua stainless hlau daim hlau.Txhua lub phaj stainless hlau tsim thiab tsim yuav muaj cov yam ntxwv zoo heev rau nws lub hom phiaj tshwj xeeb.Tus yuam sij rau kev vam meej yog kom paub qhov kev siv thawj zaug, thiab tom qab ntawd cov qib steel tsim nyog.Muaj feem ntau tsuas yog rau qib steel muaj feem xyuam rau lub hom phiaj tseem ceeb ntawm lub tsev tsim.Lawv txhua tus muaj 17-22% chromium, thiab qib hlau zoo kuj muaj npib tsib xee.Ntxiv molybdenum ntxiv txhim kho huab cua corrosion thiab tiv taus huab cua fluoride heev.
Stainless hlau phaj hais txog cov hlau uas tiv taus cov tsis muaj zog corrosive xws li roj, chav, thiab dej, thiab cov organic tshuaj corrosive xws li acid, alkali, thiab ntsev, los yog stainless hlau acid-resistant steel.Hauv cov ntawv thov tshwj xeeb, cov hlau uas tiv taus cov khoom tsis muaj zog corrosive feem ntau hu ua stainless hlau, thiab cov hlau uas tiv taus hnyav corrosion hu ua acid-resistant steel.Vim tias qhov sib txawv ntawm qhov sib txawv ntawm ob, cov qub tsis tas yuav tiv taus cov kuab tshuaj corrosion, thaum lub tom kawg yog feem ntau stainless.Lub corrosion kuj ntawm stainless hlau daim hlau yog nyob rau hauv lub aluminium alloy ntsiab nyob rau hauv cov hlau.
