Cov tsos zoo ntawm cov khoom yog ib qho tseem ceeb ntawm kev hnov lus zoo.Cov tsos mob zoo feem ntau yog hais txog cov khoom zoo ntawm cov khoom zoo, xim suab, luster, qauv, thiab lwm yam kev pom pom.
Obviously, tag nrho cov tsis xws li pob, khawb, indentations, khawb, xeb, pwm, npuas, pinholes, pits, nto tawg, delamination, wrinkles, thiab lwm yam yuav muaj kev cuam tshuam rau qhov zoo ntawm cov khoom.Tsis tas li ntawd, ntau yam khoom zoo nkauj cuam tshuam ncaj qha rau cov khoom ua tau zoo, lub neej ntev, thiab lwm yam.Cov khoom siv nrog cov npoo du muaj zog xeb kuj, tsis tshua muaj kev sib txhuam coefficient, zoo hnav tsis kam, thiab siv zog tsawg.
Kev soj ntsuam ntawm cov khoom zoo li zoo muaj ib tug tej yam degree ntawm subjectivity.Txhawm rau txiav txim siab lub hom phiaj ntau npaum li qhov ua tau, cov kev tshuaj xyuas hauv qab no feem ntau siv rau hauv kev tshuaj xyuas cov khoom lag luam zoo.
(1)Standard qauv pawg txheej txheem.Ua ntej xaiv cov qauv tsim nyog thiab tsis tsim nyog raws li cov qauv qauv, qhov twg cov qauv tsis tsim nyog muaj ntau yam tsis xws luag nrog qhov sib txawv ntawm qhov hnyav.
Cov qauv qauv tuaj yeem rov ua dua los ntawm ntau tus neeg soj ntsuam (cov neeg soj ntsuam) thiab cov txiaj ntsig kev soj ntsuam tuaj yeem raug txheeb xyuas.Tom qab txheeb xyuas cov txiaj ntsig kev txheeb cais, nws muaj peev xwm txiav txim siab seb pawg twg tsis raug teev tseg;Cov neeg soj ntsuam twg tsis muaj kev nkag siab tob txog cov qauv;Cov neeg soj ntsuam twg tsis muaj kev cob qhia tsim nyog thiab kev txawj ntse.
(2)Diam duab kev soj ntsuam.Los ntawm kev yees duab, tsim nyog cov tsos thiab kev txwv tsis pub muaj peev xwm tuaj yeem sawv cev los ntawm cov duab, thiab cov duab zoo ib yam ntawm ntau yam tsis xws luag tuaj yeem siv rau kev soj ntsuam sib piv.
(3)Txoj kev amplification defect.Siv lub iav tsom iav los yog lub projector kom nthuav dav qhov chaw ntawm cov khoom thiab tshawb xyuas qhov tsis xws luag ntawm qhov pom, txhawm rau txiav txim siab qhov xwm txheej thiab qhov hnyav ntawm qhov tsis xws luag.
(4)Disappearance nrug txoj kev.Mus rau ntawm qhov chaw siv khoom, tshuaj xyuas cov khoom siv cov xwm txheej, thiab saib xyuas cov khoom siv raws li txoj cai.Tom qab ntawd simulate qhov kev siv tiag tiag ntawm cov khoom, thiab qhia lub sijhawm sib xws, kev soj ntsuam nrug, thiab lub kaum sab xis raws li kev soj ntsuam rau kev tshuaj xyuas.Piv txwv li, yog tias qee yam khoom tsis zoo tuaj yeem pom tsis pub dhau 3 vib nas this los ntawm qhov deb ntawm ib meter, nws raug suav tias tsim nyog, txwv tsis pub nws suav tias tsis tsim nyog.Txoj kev no yooj yim dua thiab siv tau ntau dua li kev teeb tsa cov qauv khoom los ntawm cov khoom raws li ntau hom thiab qhov hnyav ntawm qhov tsis xws luag, thiab ua cov khoom kuaj xyuas los ntawm cov khoom.
Piv txwv li: Kev soj ntsuam zoo ntawm galvanized txheej ntawm cov khoom.
① Cov kev xav tau zoo.Qhov zoo ntawm cov txheej galvanized muaj xws li plaub yam: xim, uniformity, tso cai tsis xws luag, thiab tsis pub dawb.
Xim.Piv txwv li, txheej galvanized yuav tsum yog lub teeb grey nrog me ntsis beige xim;Tom qab raug rau lub teeb, cov txheej galvanized dhau los ua cov nyiaj dawb nrog ib qho luster thiab me ntsis ntawm lub teeb xiav;Tom qab kev kho phosphate, txheej txheej galvanized yuav tsum yog lub teeb grey rau nyiaj grey.
Kev tsis sib xws.Cov txheej txheej galvanized yuav tsum muaj qhov zoo nkauj crystallized, zoo ib yam, thiab tas mus li nto.
Tso cai tsis xws luag.Piv txwv li, me ntsis dej cim;me ntsis fixture marks rau saum npoo ntawm qhov tseem ceeb heev;Muaj qhov sib txawv me ntsis ntawm cov xim thiab gloss ntawm tib qhov.
Tsis pub muaj qhov tsis xws luag.Piv txwv li, blistering, tev, hlawv, nodulation, thiab pitting ntawm txheej;Dendritic, spongy, thiab striped coatings;Tsis huv ntsev stains, thiab lwm yam.
② Kev kuaj pom zoo.Rau qhov tseem ceeb, qhov tseem ceeb, qhov loj, thiab qhov zoo tib yam nrog cov khoom loj ntawm tsawg dua 90 daim, qhov zoo li yuav tsum raug tshuaj xyuas 100% txhawm rau tshem tawm cov khoom tsis haum;Rau cov khoom zoo tib yam nrog cov batch loj dua 90 daim, kev kuaj xyuas yuav tsum tau ua, nrog rau qib kev soj ntsuam dav dav ntawm II thiab qib tsim nyog ntawm 1.5%.Kev tshuaj xyuas yuav tsum tau ua raws li cov qauv tshuaj ntsuam xyuas ib txwm tau teev tseg hauv Table 2-12.Thaum pom cov khoom tsis sib haum, nws raug tso cai ua 100% kev tshuaj xyuas ntawm cov khoom, tshem tawm cov khoom tsis sib haum, thiab xa rov qab rau kev tshuaj xyuas.
③ Cov txheej txheem tshuaj xyuas qhov tshwm sim thiab kev soj ntsuam zoo.Kev kuaj pom pom yog txoj hauv kev tseem ceeb rau kev kuaj pom, thiab yog tias tsim nyog, 3-5 zaug iav tsom iav tuaj yeem siv rau kev tshuaj xyuas.Thaum kuaj xyuas, lub teeb hluav taws xob tawg los yog lub teeb xa hluav taws xob dawb uas tsis muaj lub teeb pom kev yuav tsum tau siv.Lub illuminance yuav tsum tsis pub tsawg tshaj 300 Lux, thiab qhov deb ntawm qhov chaw thiab tib neeg lub qhov muag yuav tsum yog 250 hli.Yog tias batch loj yog 100, tus qauv loj ntawm 32 daim tuaj yeem xaiv tau;Los ntawm kev tshuaj xyuas qhov muag ntawm 32 daim no, pom tau hais tias ob ntawm lawv muaj hlwv ntawm cov txheej thiab cov cim hlawv.Raws li cov khoom lag luam tsis sib haum yog 2, pawg ntawm cov khoom no tau suav tias tsis tsim nyog.
