H-Nqaj Hlau Pretreatment Txheej Txheem thiab Cov Ntsiab Lus Tseem Ceeb

Pretrice ntawm h-nqaj ua ntej vuam lossis xim pleev xim yog ib qho tseem ceeb ua kom ntseeg tau cov khoom siv thiab kav ntev. Cov txheej txheem suav nrog cov theem hauv qab no:

1. Nto Tu

Abrasive Blasting (foob / xuab zeb Blasting) tshem tawm zeb teev, xeb, thiab vuam slag kom ua tiav sa2.5 Kev nyiam huv (ISO} qauv txheej txheem nplaum.

Roj thiab roj yog tshem tawm siv cov tshuaj ntxuav alkaline lossis cov kuab tshuaj organic los tiv thaiv kom tsis txhob muaj paug.

2. Ncaj Nrees & Flattening

Hydraulic Straightening Machine Kho Kom Zoo Hauv Flange Thiab Web tshwm sim los ntawm kev tuav lossis txiav, tswj kom ncaj dua los yog sib npaug rau 1mm / m.

3. Txiav & Beveling

Milling los yog nplaim taws txiav kev npaj Weld pob qij txha nrog bevels meej (v-groove, k-bevel, etc.)

Bevel ANGLE Kev Ua Phem: tsawg dua lossis sib npaug ntawm ± 2 degree

Hauv paus lub ntsej muag thickness txawv: tsawg dua los yog sib npaug rau 0. 5 hli

4. Primer txheej (yeem)

Ib qho zinc-nplua nuj Epoxy Primer (DFT ntau dua lossis sib npaug rau 20μm) tau thov rau kev tiv thaiv corrosion ib ntus. Nco tseg: Zam Txim Txheej Weld aav yog vuam yog vuam.

5. Kev Soj Ntsuam Zoo

Daj roughness (ra 30 ~ 704 cm) tau txheeb xyuas siv prolatometer.

Txheej tuab yog soj ntsuam nrog lub ntsuas cua sib nqus.

Bevel Qhov Ntev yog tshuaj xyuas tawm tsam kev kos duab.

Pretreated H-kab teeb yuav tsum muab cia rau hauv qhov chaw qhuav, paug kom muaj kev tsis muaj zog kom muaj qhov zoo ua ntej vuam lossis pleev xim.
