Cov xwm txheej nplaum ntawm cov khoom tsis zoo hauv cov xim pleev xim rau steel coil
Cia peb tham txog ib qho teeb meem kev ntxhov siab tshaj plaws hauv lub ntiaj teb cov duab ua ntej nws tsis xav kom muaj cov txheej txheem tshiab rau cov kab, tab sis thaum koj pib pleev xim zoo li sunburnt daim tawv nqaij . Tsis yog ib qho kev puas tsuaj zoo, tsis muaj kev puas tsuaj rau kev puas tsuaj, thiab muaj kev npau taws rau cov khoom kom zoo nkauj, thiab cov khoom lag luam kom npau taws
Dab tsi tiag "tsis zoo adhesion" txhais tau tias?
Cov nplaum tsis zoo- Qee zaum hu ua "Delamination" yog tias peb tau ua qhov tsis zoo ntawm cov qhob cij {{}}}}}}}}
Hauv cov ntsiab lus tshaj lij, nws yog qhov tsis ua tiav ntawm cov khoom siv kom zoo li cov kab xev hlau uas tau txiav Cov teeb meem nplaum nplaum .
Tab sis vim li cas koj thiaj yuav tsum tau tu? Zoo ...

Cov khoom nqa nyiaj txiag plummets zoo li lub pob zeb .
Vim li cas qhov no txawm tshwm sim? Wb ua si Detective
Yog tias adhesion tau yooj yim, peb yuav tsis muaj qhov kev sib tham no . qhov tseeb? It's a messy combination of material science, process control, and sometimes just plain human error. Let's look at the usual suspects:
1. Cov seev cev qias neeg - nto prec prep mus tsis ncaj ncees lawm
Tus naj npawb ib qho ua txhaum cai nyob txog 60% ntawm adhesion ua tsis tiav? Tsis zoo saum npoo tu . niaj hnub hlau coils tsis xa tawm npaj txhij-rau-lub tsho tiv no. Lawv tuaj nrog cov yeeb ncuab uas pom tsis tau:
Dov cov roj ntawm cov zeb (cov uas ua rau cov neeg nplua nuj)
Xeb blooms los ntawm cov av cia
Ntiv tes los ntawm kev tuav (yog, tiag tiag)
Cov plua av me me, koj xav tau lub tsom iav pom kom pom
Yog tias txoj kab kev ntxuav tsis ua nws txoj haujlwm - tej zaum siv tshuaj lom neeg tsis huv, lossis cov txheej txheem tsis muaj dab tsi zoo dua, lossis cov khoom tseem ceeb} Nws zoo li cov iav ua ke {}}
