1.Yog dab tsi kev ntxhov siab thaum khoov tau muaj cov txheej?
Cov txheej txheej tsis yog ductile txaus los ua raws li kev deformation ntawm substrate
Cov xim xim tsuas yog tsim cov khoom cob, xim thiab ntxiv, thiab nws lub ductility yog qhov qis dua li ntawm cov hlau substrate.
Thaum tus khoov rau lub kaum ntse ntse, lub substrate yuav yauv tawm cov khoom tawg yooj yim, thiab yog tias txheej txheej tsis muaj txaus, nws yuav raug yuam kom ncab ", ua rau tawg sab hauv. Yog hais tias cov kab nrib pleb mus nqus cov txheej, xim yuav poob thiab tev tawm. ◦ Thaum cov txheej txheej txheej tuab tuab heev, cov txheej txheem yuav txo qis dua (tuab dua yog kev tawg ")
Kev ntxhov siab ntawm kev khoov ntau dua cov nplaum kom txwv ntawm cov txheej
Qhov chaw khoov yog thaj chaw uas muaj kev tiv thaiv loj heev, thiab kev sib tshuam ntawm cov txheej thiab cov txheej txheem loj yuav raug rau cov kev ntxhov siab loj loj. Yog tias cov nplaum (piv txwv li tsev pheeb suab lub zog) nruab nrab ntawm txheej thiab lub substrate yog qhov tsis txaus ntseeg, ua rau cov txheej ntawm cov npoo ntawm substrate.
2.Qhov dab tsi yog qhov ua tsis taus kev ua rau nws tus kheej?
Cov txheej txheej tsis yog tawv txaus thiab yog heev nkig
Qhov nyuaj ntawm cov txheej muaj feem xyuam rau hom cob thiab qib ntawm kev kho: ◦ resin hom: ◦ Resin Tawv thiab muaj txhij rau nkig tawg thaum khoov nkoj tawg thaum khoov nkoj; Thaum cov txheej txheem polyester thiab fluorocarbon muaj cov roj thiab zoo dua tsis kam. Kev ntsuas kub dhau los: Yog tias qhov ntsuas kub siab dhau los yog lub sijhawm ntev dhau thaum sib txuas, tsis muaj qhov nyuaj, tsis muaj qhov tsis muaj dab tsi thaum uas yog khoov, thiab yooj yim poob.
Uneven txheej tuab lossis pinholes
Yog tias muaj nyias cov me me, pinholes lossis npuas nyob rau hauv qhov txheej nws tus kheej ntawm cov khoov, cov kev tsis muaj zog yuav dhau los ua cov ntsiab lus tsis muaj zog "uas muaj kev ntxhov siab. Thaum khoov, qhov kev ntxhov siab tau tawm ua ntej los ntawm qhov tsis xws, ua rau txheej txheej kom tawg thiab poob tawm ntawm qhov tsis xws luag.
3.Qhov dab tsi yog qhov cuam tshuam ntawm substrate thiab pretrice?
Tsis zoo sab nraud ntawm substrate
Thaum muaj burrs lossis pits rau ntawm qhov chaw ntawm substrate (xws li steel phaj), khoov yuav ua rau cov txheej txheem hauv cov ntu no kom tawg, ua rau pleev xim rau poob.
Yog tias zinc txheej ntawm cov ntawv galvanized muaj cov khoom tsis zoo (xws li xoob
Pretreatment txheej txheem tsis xws luag
Passivation yog ib kauj ruam tseem ceeb los txhim kho cov nplaum ntawm txheej thiab tsis sib xws, nws tsis sib haum, thiab lub interface yog ib qho yooj yim cais thaum khoov.
Yog tias cov dej ntxuav tom qab kev hla kev tsis tiav, xws li cov kua nyeem uas tseem tshuav (xws li cov kua qaub thiab alkali yuav ua rau muaj kev sib raug zoo thiab txo cov kev tawm tsam kev ua haujlwm.
4.What hom kev cuam tshuam dab tsi tsis tsim nyog cov txheej txheem tsis raug?
Txoj kev xauj tsev yog tsawg heev
Qhov me dua cov burnively bending radius (piv txwv li qhov loj ntawm cov fillet ntawm khoov), ntau dua cov txheej txheem ncab ntawm txheej. Yog tias lub vojvoog me dua qhov tsawg kawg nkaus khoov xo hluav taws xob uas yuav tsum tau tiv thaiv hluav taws xob ntau dua lossis sib npaug ntawm 3 zaug tuab yuav tsis muaj kev cuam tshuam rau kev sib tsoo ntau dhau.
Dabtsi yog khoov ceev ceev dhau los yog quab yuam yog qhov tsis ncaj
Kev sib tw ceev ceev yuav ua rau cov txheej sib xyaw ua kom muaj kev cuam tshuam kom sai, thiab yuav tsis muaj sijhawm los ua kom tsis muaj kev cuam tshuam; Thaum lub zog tsis ncaj (xws li kev sib tiv tauj tsis sib xws ntawm cov khoov thiab lub phaj) yuav ua rau muaj kev ntxhov siab ntau hauv zos, thiab pleev xim puxing ua ntej.
5.Qhov yog qhov ntsuas tseem ceeb kom tiv thaiv kev puas thiab pleev xim xas?
Txhim kho txheej txheem ua haujlwm: xaiv cov khoom siv hluav taws xob ntau (feem ntau yog cov duab tuab), feem ntau 50 ~ 100μm qhuav zaj duab xis tuab yog tsim nyog), thiab zam dhau txoj kev kho.
Ntxiv dag zog rau Pretricement: xyuas kom meej tias lub substrate yog dawb ntawm cov burrs thiab roj stains yog unensorm thiab ntom, thiab txheej nplaum adhesion tau txhim kho.
Tsim Nyog Quav Dabtsi Yog Khoov Tsis Tau: Xaiv qhov tsim nyog buterius raws li lub vojvoog nyias muaj peev xwm yoog raws li lub tshuab hluav taws xob me me), tswj hwm kev sib dhos ceev thiab quab yuam kev sib dhos.
