1.Dab tsi yog qhov tseem ceeb ntawm kev ntsuas kev ua qias tuaj?
Lub hauv paus ntawm kev ntsuam xyuas cov pa phem yog simulate cov pa phem uas yuav raug ntsib hauv kev siv tiag tiag (xws li cov plua plav, roj, cov pa phem hauv huab cua, thiab lwm yam), thiab txheeb xyuas qhov kev tiv thaiv -kev ua qias tuaj thiab yooj yim- rau- ntxuav lub peev xwm ntawm cov txheej los ntawm "kev ua qias tuaj{{4}" evaluation.
2.Dab tsi yog cov kauj ruam hauv kev ntsuas kev tiv thaiv?
Kev npaj ua qauv
Xaiv cov xim sawv cev-cov qauv coated coil los xyuas kom meej tias tsis muaj qhov tsis xws luag ntawm txheej txheej (xws li khawb thiab npuas). Ua ntej kev sim, pretreatment yuav tsum tau raws li tus qauv yuav tsum tau (xws li muab tso rau hauv ib tug tas li kub thiab av noo ib puag ncig rau 24 teev).
Kev xaiv cov pa phem
Cov pa phem raug xaiv raws li daim ntawv thov scenario. Cov hom muaj xws li:
Cov khoom muaj kuab paug: xws li cov pa roj carbon dub, ya tshauv, quartz xuab zeb, thiab lwm yam, feem ntau ua rau hauv qhov kev ncua ntawm qee qhov concentration.
Cov kua paug ua kua: xws li cov roj cav, kua ntses / kua txiv kab ntxwv, sulfate tov, number case, thiab lwm yam.
Biological pollutants: xws li pwm spore suspension.
Kev ua qias tuaj thiab sawv
Siv cov smearing, txau los yog immersion los npog cov pa phem ntawm cov qauv saum npoo.
Sawv ntsug rau ib lub sij hawm nyob rau hauv ib qho chaw tshwj xeeb raws li tus qauv yuav tsum tau tso cai rau cov pa phem kom tag nrho los yog cuam tshuam nrog cov txheej txheem.
Kev kho mob ntxuav
Simulate txoj kev ntxuav tiag tiag, xws li yaug nrog dej deionized, so nrog ib daim ntaub mos mos dipped hauv dej huv (5-10 zaug rov qab), los yog so nrog cov tshuaj detergent rau cov kab mob oily thiab ces yaug.
Tom qab ntxuav, muab cov qauv tso rau hauv qhov chaw ib puag ncig kom qhuav (feem ntau 24 teev).
3.Qhov ntsuas ntsuas yog dab tsi?
Kev pom kev pom zoo, kev hloov xim sib txawv (ΔE), gloss retention, residual contamination area ratio, coating performance change
4.Qhov kev ntsuam xyuas yog dab tsi?
Kev pom qhov pom kev ntsuas: Qib 1 (tsis muaj qhov seem seem); Qib 2 (qhov seem me ntsis, tsuas yog pom ntawm qhov ze); Qib 3 (pom tseeb, tab sis cheeb tsam<10%); Level 4 (residue area 10%-30%); Level 5 (residue area >30% lossis coating discoloration / puas).
Xim sib txawv (ΔE)
Siv lub colorimeter los ntsuas qhov sib txawv xim ΔE ntawm cov qauv ntxuav thiab qhov chaw tsis huv (lossis cov qauv qub) (ΔE=√[(ΔL*)²+(Δa*)²+(Δb*)²], qhov twg L yog lightness thiab a/b* yog xim ua haujlwm).
Gloss tuav tus nqi
Siv lub ntsuas gloss los ntsuas 60℃gloss tus nqi (G1) thiab tus nqi qub gloss (G0) ntawm cov qauv ntxuav, thiab xam tus nqi tuav (G1 / G0 × 100%).
Tus nqi tuav tau ntau dua lossis sib npaug li 90% yog "zoo heev", 70% -90% yog "zoo", thiab<50% is "poor" (obvious loss of gloss due to contamination).
Residual contamination area ratio
Use image processing software (such as Photoshop) to calculate the ratio of the residual stain area to the total contaminated area. ≤5% is "excellent", 5%-15% is "good", and >30% yog "neeg pluag".
Kev hloov ntawm txheej txheej
Yog tias cov kab mob sib kis ua rau cov txheej txheem puas tsuaj, yuav tsum tau kuaj ntxiv adhesion (xws li tus ntoo khaub lig-txiav txoj kev GB/T 9286). Yog tias qhov adhesion txo qis dua los yog sib npaug rau 1 qib (xws li los ntawm qib 0 mus rau qib 2), qhov kev ntsuas tsis zoo yog txo.
5.Dab tsi lwm yam yuav tsum tau xav txog nyob rau hauv kev siv tswv yim?
Kev ntsuas kev laus nrawm nrawm: Kev ua pa phem tuaj yeem cuam tshuam los ntawm lub sijhawm ntev - ultraviolet rays, kub kub, thiab av noo. Yog li ntawd, nws yog ib qho tsim nyog los ua ke cov kev ntsuam xyuas kev laus (xws li kuaj cov pa phem tom qab 1000 teev ntawm kev laus ultraviolet) txhawm rau ntsuas qhov muaj peev xwm tiv thaiv - pa phem ntawm txheej tom qab kev laus.
Tus kheej-Kev ntsuas kev ua haujlwm tu tus kheej: Rau cov xim-coated coils uas hais txog "tus kheej- ntxuav" (xws li fluorine- muaj cov coatings), kev sib cuag lub kaum sab xis (dej cov ces kaum> 110℃feem ntau suav hais tias yog super-hydrophobic thiab muaj kev siv tus kheej zoo li qub){6} - lub kaum sab xis loj dua, nws yooj yim dua rau cov pa phem kom raug ntxuav los ntawm cov dej nag, thiab qhov zoo dua cov pa phem.
Kev kuaj qhov chaw raug: Muab cov qauv tso rau hauv qhov xwm txheej ntawm daim ntawv thov (xws li thaj chaw muaj kev lag luam thiab thaj chaw ntug dej hiav txwv) rau 6-12 lub hlis, thiab tsis tu ncua saib cov pa phem ntawm qhov chaw thiab kev tu kom tsis tu ncua raws li kev soj ntsuam ntxiv ntawm kev kuaj sim.
