Niaj hnub no, hwm Q235 steel coils yog cov khoom siv nrov tshaj plaws rauhnub ci txoj kev ncej. Vim lub hnub ci txoj kev teeb yuav raug cua, hnub, thiab nag, lawv lub neej ntev nyob ntawm lawv lub peev xwm los tiv thaiv corrosion. Cov hlau feem ntau yog galvanized los txhim kho qhov no.
Muaj ob hom zinc plating: kub-dip thiab txias-dip galvanizing. Vimkub-dip galvanized steel ncejmuaj ntau resistant rau corrosion, peb feem ntau qhia yuav lawv. Dab tsi yog qhov txawv ntawm kub-dip thiab txias-dip galvanizing, thiab vim li cas ho kub-dip galvanized ncej muaj superior corrosion kuj? Cia peb saib nrog Tianxiang, lub tuam txhab nto moo Suav txoj kev ncej.
I. Cov ntsiab lus ntawm Ob
1) Cold Galvanizing (tseem hu ua electro-galvanizing): Tom qab degreasing thiab pickling, cov hlau yog muab tso rau hauv ib tug zinc ntsev tov. Qhov kev daws teeb meem yog txuas nrog qhov tsis zoo electrode ntawm cov khoom siv electrolysis, thiab ib lub phaj zinc muab tso rau sab nraud, txuas nrog qhov zoo electrode. Thaum lub hwj chim qhib, raws li qhov tam sim no txav mus los ntawm qhov zoo mus rau qhov tsis zoo electrode, ib qho zoo, ntom, thiab zoo-bonded zinc deposit txheej txheej ntawm cov yeeb nkab steel.
2) Kub-dip galvanizing: steel nto yog submerged nyob rau hauv molten zinc tom qab ntxuav thiab ua kom tiav. Ib txheej ntawm cov hlau zinc tsim nyob rau ntawm cov hlau nto vim yog cov tshuaj tiv thaiv physicochemical ntawm cov hlau thiab zinc ntawm qhov sib cuam tshuam. Piv rau qhov txias galvanizing galvanizing galvanizing, cov qauv no ua rau cov txheej sib txawv ntawm cov txheej thiab cov txheej txheem ua kom ruaj khov, kev saib xyuas-dawb, thiab tus nqi-ua hauj lwm zoo.
II. Qhov txawv ntawm Ob
1) Txoj Kev Ua Haujlwm: Lawv cov npe ua kom pom qhov txawv. Zinc tau nyob rau hauv chav tsev kub yog siv nyob rau hauv txias-dip galvanized steel kav, whereas zinc tau ntawm 450 ° C mus rau 480 ° C yog siv nyob rau hauv kub-dip galvanizing.
2) Txheej Thickness: Txawm hais tias txias-dip galvanizing feem ntau tsim cov txheej tuab ntawm tsuas yog 3-5 μm, uas ua rau kev ua haujlwm yooj yim dua, nws muaj qhov tsis zoo corrosion. Nyob rau hauv sib piv, kub-dip galvanizing feem ntau muaj txheej thickness ntawm 10μm los yog ntau tshaj, uas yog ob peb kaum ntawm lub sij hawm ntau corrosion resistant tshaj txias-dip galvanized lub teeb ncej.
3) Txheej Txheej: Txheej txheej thiab substrate yog sib cais los ntawm kev sib piv cov txheej txheej txheej hauv kub-dip galvanizing. Txawm li cas los xij, vim tias cov txheej txheem yog ua los ntawm zinc tag nrho, uas ua rau cov txheej txheem tsis sib xws nrog ob peb lub qhov hws, ua rau nws tsis tshua muaj corrosion, qhov no tsis tshua muaj kev cuam tshuam rau nws cov kev tiv thaiv corrosion. Nyob rau hauv sib piv, txias-dip galvanizing siv ib txheej ua los ntawm zinc atoms thiab ib tug adhesion txheej txheem ntawm lub cev nrog ntau qhov hws, uas ua rau nws raug rau ib puag ncig corrosion.
4) Nqe sib txawv: Kev tsim cov kub-dip galvanizing yog qhov nyuaj thiab nyuaj. Yog li ntawd, cov tuam txhab me nrog cov cuab yeej qub feem ntau siv txias-dip galvanizing, ua rau cov nqi qis dua. Loj, tsim ntau dua kub-dip galvanizing manufacturers feem ntau muaj kev tswj kom zoo dua qub, ua rau cov nqi siab dua.
Ⅲ. Yuav ua li cas paub qhov txawv ntawm Cold-Dip Galvanizing thiab Kub-Dip Galvanizing
Qee tus neeg yuav hais tias txawm tias lawv paub qhov txawv ntawm qhov txias-dip galvanizing thiab kub-dip galvanizing, lawv tseem tsis tuaj yeem qhia qhov txawv. Cov no yog cov txheej txheem ua uas tsis pom ntawm qhov muag liab qab. Yuav ua li cas yog ib tug tub lag luam uas unscrupulous siv txias-dip galvanizing es tsis txhob kub-dip galvanizing? Qhov tseeb, tsis tas yuav txhawj xeeb. Txias-dip galvanizing thiabkub-dip galvanizingyog qhov yooj yim heev kom paub qhov txawv.
Txias-dip galvanized nto yog tus du, feem ntau yog daj-ntsuab, tab sis qee qhov yuav muaj iridescent, xiav-dawb, los yog dawb nrog ib tug ntsuab sheen. Tej zaum lawv yuav tshwm sim me ntsis npub lossis qias neeg. Kub-dip galvanized nto, nyob rau hauv kev sib piv, yog me ntsis rougher, thiab tej zaum yuav muaj zinc paj, tab sis lawv zoo li ci heev thiab feem ntau silvery-dawb. Ua tib zoo saib xyuas qhov sib txawv no.
