Galvanized Steel Hlau rau Ua Rau Tes

Galvanized steel xaim yog cov khoom siv dav siv rau cov ntsia hlau hlau yog muaj txiaj ntsig zoo, thiab cov txheej txheem galvanization los ua ib qho txheej txheem galvanization los ua ib qho kev tiv thaiv kab mob zinc. Qhov txheej txheem no ua rau muaj kev cuam tshuam nrog xeb thiab corrosion, txuas ntxiv rau cov xaim hlau, tshwj xeeb tshaj yog nyob rau hauv sab nraum zoov lossis siab} noo noo sij hawm.

Electro Galvanized Hlau Hlau yog paub rau nws cov du thiab tsis sib haum zinc txheej, uas tsis tsuas yog muab kev tiv thaiv zoo tab sis kuj yog qhov tsos. Nws muaj qhov nruab nrab lub zog thiab hloov tau yooj yim, ua rau nws yooj yim daws thiab ua tiav. Cov kev siv cov ntawv thov feem xyuam suav nrog kev siv hlua khi rau hauv kev tsim kho thiab ntim khoom, thiab kuaj xyuas cov laj kab thiab kev tshuaj ntsuam txhua yam uas yuav tsum tau ua.

Lub thickness ntawm zinc txheej tuaj yeem sib txawv raws li cov kev xav tau, tso cai rau customization raws li ib puag ncig uas cov hlau yuav raug siv. Feem ntau, ib qho zinc txheej tuab muaj cov tshuaj tiv taus corrosion zoo dua tab sis kuj tseem tuaj yeem nce tus nqi. Hom xov hlau no ntaus qhov sib npaug ntawm kev ua tau zoo thiab raug nqi, ua rau nws xaiv nrov hauv ntau qhov kev lag luam.

1. Cov Khoom Siv Khoom Raw

Ntsiab xov hlau: Tsawg {-} cov hlau xaim hlau xaim (SAE 1006618, 0.05-0.25% carbon).

Qhov dav: Feem ntau 5.5-9 hli (ua ntej -} kos duab).

Saib:

Alkaline Degrite (60-80 Degree Naoh daws) kom tshem roj.

Neeg kho tshuab descaling (txhaj tshuaj tiv thaiv blasting) lossis acid pickling (10-15% hcl / h₂so₄, 20-30 degree).

Thov: Mineutralization hauv dej da dej (pH 7).

2. Xaim kos duab

Lub hom phiaj: Txo cov cheeb tsam hla mus rau lub hom phiaj loj (piv txwv li, 0.15-6.0 hli).

Kev ua:

Qhuav / ntub kos duab los ntawm carbide / pob zeb diamond tuag.

Lubrication: xab npum hmoov lossis calcium stearate emulsion.

Ntau tus dhau (piv txwv li, 8-12 theem) nrog kev txhawb nqa nruab nrab.

Ib tug anerting:

Batch / txuas ntxiv rauv (650-750 degree) los rov ua dua.

Kev tswj cov cua (n₂ / h₂) los tiv thaiv oxidation.

3. Electro - galvanizing kab

4. Tiav thiab Kev Tswj Xyuas Zoo

5. Ib puag ncig & kev ntsuas kev nyab xeeb

Kev lag luam - Tshwj xeeb cov cwj pwm

Zoo heev tas qhov ruaj khov
Galvanized xaim yog tsim siv cov cuab yeej ua luam yeeb Nplooj ntawv, nrog xaub hlau npau taws rau ± 0.02 hli. Lawv tau tshaj nrog cov khoom siv pwm thiab cov qauv pwm, pab tswj cov khoom siv ruaj khov thiab cov txheej txheem raug. Qhov no txo ​​qis kev pheej hmoo ntawm cov khoom siv jamming thiab tsis ua neeg tsis ntseeg, thiab txhim kho cov qoob loo ntau lawm.

Zoo tshaj plaws tensile lub zog
Tom qab txheem txoj kev txhawb nqa, peb cov khoom lag luam ua tiav lub zog tensile ntawm 350-550 n / mm², sib npaug {{bearing {bearing} cov kabmob muaj peev xwm.
