1.What yog qhov tseem ceeb cuam tshuam rau cov adhesion ntub?
Resin Hom: resins xws li fluorocarbon thiab silicon-hloov polyester tseem siv cov qauv roj av, thiab yog qhov haum rau cov av noo ib puag ncig.
Decondary polyester thiab acrylic coisings muaj cov pej xeem muaj acrylic, thiab lub sijhawm noo ntev yuav ua rau txheej me me, yog li txo adhesion.
Txheej thickness thiab kev sib xws: thaum txheej txheej txheej txheej tsis txaus lossis muaj cov pinholes yooj yim lossis muaj kev xeb ntawm cov txheej thiab tsis ncaj qha ua kom rhuav tshem cov nplaum; Thaum lub sij hawm ib txwm muaj txheej txheej tuab tuaj yeem txuas lub dej vapor vapor penetration path thiab ncua kev cuam tshuam tsis ua hauj lwm.
2.How ua tau qhov zoo ntawm substrate npaj npaj thiab primerion cuam tshuam rau noo noo tsis kam?
Nto Kho:
Lub substrate yuav tsum tau ua chromate kho lossis chromium-dawb passivated los ua ib zaj duab xis hloov pauv mus txhim kho kev sib koom tes nrog tus thawj coj; Yog tias qhov pretreaticment yog tsis meej, lub vaum huab cua yuav ua kom muaj kev sib cuam tshuam.
Thawj hom:
Tus thawj coj yuav tsum muaj ob qho tib si "cov kab mob - adhesion": Epoxy Primer, thiab yog thawj qhov kev xaiv rau cov av noo; Thaum Alkyd Primer muaj dej tsis zoo thiab yog ib qho yooj yim rau emulsify nyob rau hauv lub sijhawm av noo, uas ua rau txo cov nplaum.
3.Txhog cov av noo, kub, thiab muaj kev tawm tswv yim corrosion?
Cov av noo + qhov kub: dej vapor tuaj yeem nkag mus rau cov txheej txheem ntawm cov txheej txheem rau lub interface mus rau lub corrosion ntawm substrate. Cov khoom lag luam hauv corrosion yuav tsim "wedge nyhuv" ntawm lub interface, thawb cov txheej ntxiv, ua rau muaj adhesion ploj mus.
Vaum kev nyob ib puag ncig muaj ntsev: chloride ions hauv cov tshuaj tsuag ntawm cov txheej txheem ntawm cov txheej txheem ntawm cov txheej thiab ua kom zoo nkauj, ua rau cov nplaum kom txo qis hauv lub sijhawm luv luv.
4.What yog cov kev ntsuam xyuas kev ntsuam xyuas rau cov khoom siv ntub?
Ntub Cua Sov Kuaj
Cov txheej txheem kuaj: Tso cov xim xim-coated coil qauv hauv ib qho chaw sov tas nrho thiab av noo chamber, nthuav tawm nws rau 500 thiab 1000h, ces coj nws tawm thiab qhuav nws.
Kev ntsuam xyuas dej npau npau (ua kom muaj kev ntsuas dej nkag mus tob)
Cov txheej txheem ntsuas: rawv cov qauv tso rau hauv dej npau npau npau (100 degree), cia nws rau 1-2 teev, ces coj nws mus rau lwm qhov thiab txias rau chav tsev.
Kev Ntsuas Cov Khaub Ncaws (Simulating Lub Chaw Khaub Ncaws Hnav)
Cov txheej txheem kuaj: Tso cov qauv ntawm 45 qib kom sov (kub {{{2} {{2} {{2} {}
5.Qhov yog cov kev ntsuas txhawm rau txhim kho cov nplaum nplaum ntub?
Cov Txheej Txheem Txheej Txheej Txheem: Muab qhov tseem ceeb rau cov chaw ua haujlwm nrog cov dej tsis kam rau ntau dua 25μm kom txo qis cov dej vapor penetration channel.
Substrate Pretrice kev ua tiav: Siv chromium-dawb passivation lossis phosphallation hloov dua tshiab thiab txhim kho kev siv tshuaj lom neeg nrog tus thawj.
Primer optimization: Siv Epoxy Primer txhawm rau txhim kho adhesion thiab inhibit corrosion ntawm substrate nyob ib puag ncig.
Txheej Txheem Tswj: Xyuas kom meej tias cov txheej yog kho kom zoo thiab txo cov ntxeem tau sab hauv cov txheej.
