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, gloss, qauv, thiab lwm yam uas pom tau pom. Obviously, txhua yam tsis xws li pob, abrasions, indentations, khawb, xeb, pwm, npuas, pinholes, pitting, nto tawg, delamination, wrinkles, thiab lwm yam yuav muaj kev cuam tshuam rau cov tsos zoo ntawm cov khoom. Tsis tas li ntawd, ntau yam zoo ntawm cov khoom muag ncaj qha cuam tshuam rau cov khoom lag luam, kev ua neej nyob, 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 ntsuam xyuas ntawm cov khoom zoo li zoo muaj ib tug tej yam 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 kev txheeb xyuas cov txiaj ntsig ntawm kev txheeb cais, nws tuaj yeem txiav txim siab seb pawg twg tsis raug txhais tsis raug; 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, qhov 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 magnifying lossis projector los nthuav dav cov khoom 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 kev siv. 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. Yog hais tias ib yam khoom zoo li qhov tsis xws luag tau teev tseg, tsuav yog nws tsis pom nyob rau hauv 3 vib nas this los ntawm ib tug deb ntawm ib 'meter', nws yog suav hais tias tsim nyog, txwv tsis pub nws yog xam tsis tsim nyog. Txoj kev no yooj yim dua thiab siv tau ntau dua li kev teeb tsa cov qauv thiab ua cov khoom kuaj xyuas los ntawm cov khoom raws li ntau hom thiab qhov hnyav ntawm qhov tsis xws luag.
Piv txwv li: Kev soj ntsuam zoo ntawm galvanized txheej ntawm cov khoom.
①Cov tsos zoo yuav tsum. Cov tsos zoo ntawm galvanized txheej muaj xws li plaub yam: xim, uniformity, tso cai tsis xws luag, thiab qhov tsis xws luag.
Xim. Piv txwv li, txheej galvanized yuav tsum yog lub teeb grey xim nrog me ntsis beige hue; Tom qab raug rau lub teeb, cov txheej galvanized tshwm li cov nyiaj dawb nrog ib qho gloss 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 rau qhov tsis xws luag. Piv txwv li, me ntsis dej stains; Cov khoom tseem ceeb heev, thiab muaj cov cim me ntsis ntawm qhov chaw; Muaj qhov sib txawv me ntsis ntawm cov xim thiab gloss ntawm tib qhov.
Tsis raug tso cai. Piv txwv li: blistering, tev, hlawv, nodulation, thiab pitting ntawm txheej; Dendritic, daim txhuam cev zoo li, thiab kab txaij txheej; Tsis huv ntsev stains, thiab lwm yam.
②Sampling rau kev soj ntsuam zoo li qub. Rau qhov tseem ceeb, qhov tseem ceeb, qhov loj, thiab qhov zoo tib yam nrog cov khoom loj ntawm tsawg dua 90, qhov zoo li yuav tsum raug tshuaj xyuas 100% thiab cov khoom tsis sib haum yuav tsum raug tshem tawm; 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 tsim nyog, nws raug tso cai los tshuaj xyuas cov batch 100%, tshem tawm cov khoom tsis tsim nyog, thiab xa rov qab rau kev tshuaj xyuas.
③Cov 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 lub sij hawm soj ntsuam, lub ntuj tawg los yog lub teeb xa mus dawb tsis muaj kev cuam tshuam yuav tsum tau siv, nrog lub teeb pom kev tsis tsawg dua 300 lux, thiab qhov kev ncua deb ntawm qhov chaw thiab tib neeg lub qhov muag yuav tsum yog 250 millimeters.
Yog tias batch loj yog 100, tus qauv loj ntawm 32 daim tuaj yeem muab rho tawm; Los ntawm kev tshuaj xyuas qhov muag ntawm 32 daim no, pom tau tias ob ntawm lawv muaj hlwv ntawm cov txheej thiab cov cim hlawv. Raws li tus naj npawb ntawm cov khoom tsis sib haum yog 2, nws tau txiav txim siab tias cov khoom siv no tsis ua raws.
