Kev sib piv ntawm cov txheej txheem kev kho sib txawv

Aug 29, 2025

Hauv kev tsim qauv ntawm cov qauv hlau thiab cov khoom siv hlau, cov hlau sib txuas hauv kev txhim kho huab cua tiv thaiv, zoo nkauj, thiab lub neej pabcuam. Ntawm lawv, hmoov txheej, anodizing, thiab galvanizing yog peb cov kev ua kom dav dav siv, tab sis lawv cov yam ntxwv ua tau zoo thiab cov khoom siv tau muaj txiaj ntsig tseem ceeb.

Cov ntsiab lus tseem ceeb thiab cov yam ntxwv ntawm peb tus txheej txheem

1. Hmoov txheej:
Hmoov txau siv thermosetting hmoov txheej txheem (xws li epoxy cob thiab polyester cob) raws li cov ntaub ntawv raw. Cov hmoov yog them los ntawm cov phom tsuag hluav taws xob, adsorbed nyob rau saum npoo ntawm cov hlau workpiece, thiab tom qab ntawd kho tau ntawm qhov kub ntawm 180-220℃los ua cov txheej txheem sib dhos.

Cov Nta Cov Txuj Ci: Nws tuaj yeem ua tiav cov ntau yam tshwm sim xws li matte, tseem ceeb, kev ntxhib los mos, thiab lwm yam; Muaj zog hloov kho rau cov duab ua haujlwm thiab txawm tias muaj kev pab them nqi ntawm cov qauv txheej txheem nyuaj.

2. Anodizing:
Anodizing tsuas yog siv rau txhuas thiab aluminium alloys. Los ntawm kev tso cov haujlwm ua haujlwm raws li anode hauv cov tshuaj electrolyte (xws li sulfuric acid lossis oxalic acid) thiab thov cov yeeb yaj kiab tam sim no xide yog tsim rau saum npoo.
Cov Nta Cov Txuj Ci: Cov yeeb yaj kiab oxide yog qhov txuas ntxiv ntawm cov xim ntuj ntawm cov hlau, nrog cov ntaub ntawv zoo nkauj; Zaj duab xis muaj siab tawv thiab hnav tsis kam tiv.

3. Galvanization:
Galvanizing yog cov txheej txheem ntawm kev sib sau ib qho zinc txheej ntawm cov npoo hlau ua haujlwm los ntawm cov hau kev xws li electrolysis, kub ntswj, thiab zinc infiltration. Cov txheej txheem sib xws suav nrog galvanizing galvanizing (txias txias), kub}}}}} dip galvanizing), thiab cov neeg kho tshuab galvanizing.
Cov Nta Cov Txuj Ci: tsuas muaj siv rau cov ntaub ntawv hlau; Kub dip Galvanizing muaj cov txheej tuab thiab muaj zog nplaum thiab muaj zog nplaum thiab hluav taws xob galvanizing galvanizing yooj yim dua kom ua tiav kev tswj hwm kom zoo.

Kev sib txawv ntawm kev sib piv ntawm cov kev ua tau zoo ntev
