Tom qab ntau tshaj 20 xyoo ntawm txoj kev loj hlob ntawm Tuam Tshoj txoj kev lag luam tsheb, feem ntau ntawm cov tawv nqaij ntawm cov tsheb npav thiab cov tsheb npav yog stamped los ntawm kev tuag, lub flatness ntawm lub cev yog zoo heev, tus nqi ntawm atomic tshauv yog heev txo, tsuas yog lub zos siv atomic tshauv. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau lub cev yog txau nrog cov txheej txheem nruab nrab, tab sis tsis yog coated nrog atomic tshauv, adhesion ntawm nruab nrab txheej thiab electrophoretic primer tsis zoo, adhesion ntawm lub putty yog zoo heev. lub adhesion thaum scraping putty nyob rau hauv lub tsheb kuj zoo heev. Hauv kev teb rau cov teeb meem tshiab uas tau tshwm sim, peb tau ua txoj haujlwm sib tham hauv qab no thiab npaj cov kev daws teeb meem rau cov teeb meem uas tau tshwm sim.
1. Kev cuam tshuam ntawm atomic tshauv ntawm adhesion ntawm txheej
Siv 11 hom atomic tshauv ntawm qib sib txawv (xws li atomic tshauv tsim nyob rau hauv Nyiv thiab lub teb chaws Yelemees) rau kev sim, qhov saum npoo ntawm ci electrophoretic primer phaj (150mm × 70mm × 1mm) tau wiped huv si nrog huv huv gauze (tsis polishing cov xim nto. ), ib nrab coated nrog atomic tshauv, 20min txij thaum pib ntawm atomic tshauv txheej, muab tso rau hauv ib lub qhov cub nrog qhov kub thiab txias ntawm 140 degree rau 30min thiab coj tawm. Muab tso rau ntawm chav tsev kub rau 60min, ces siv 320 # dej xuab zeb los xuab zeb atomic tshauv nto (tsis txhob xuab zeb ntawm lub electrophoretic primer uas tsis coated nrog atomic tshauv), thiab cia cov tsim atomic tshauv hmoov av slurry ntws nrog dej mus qhov saum npoo ntawm electrophoretic primer uas tsis yog coated nrog atomic tshauv. Qhuav tus qauv ntawm chav tsev kub, thiab tom qab ntawd so cov plua plav ntawm cov qauv nrog cov ntaub qhwv huv huv. Tom qab pleev xim rau saum npoo ntawm cov qauv, nws muab tso rau hauv qhov cub nrog qhov kub thiab txias ntawm 140 degree thiab ci rau 30min, thiab cov qauv raug tshem tawm thiab muab tso rau hauv chav sov li 60min, thiab tib lub sijhawm, cov phaj primer tsis muaj. atomic tshauv yog coated thiab pleev xim rau, thiab ci hauv qhov cub nrog qhov kub thiab txias ntawm 140 degree rau 30min, thiab cov qauv raug coj tawm thiab muab tso rau hauv chav tsev kub rau 60min, thiab qhov adhesion yog kuaj nrog ib tug sau ntawv.
Cov kev sim qhia tau hais tias qhov adhesion ntawm lub txheej yog tsis zoo nyob rau hauv ib nrab ntawm uncoated atomic tshauv, thiab adhesion ntawm ib nrab ntawm cov coated atomic tshauv yog nyob nruab nrab ntawm 0 ~ 1 qib.
Vim tias qhov sib ntxiv ntawm cov dej kub npau npau ntxiv xws li cov tshuaj tua kab mob, cov tshuaj tiv thaiv kab mob, cov tshuaj dispersants thiab lwm cov khoom kub kub kub ntxiv rau cov dej-raws li electrophoretic primer, cov additives yuav ntab rau ntawm cov xim pleev xim thaum ci thaum kub kub, thiab cov additives no yuav tsim ib tug ciam teb tsis muaj zog txheej nrog atomic tshauv plua plav, cuam tshuam lub adhesion ntawm primer thiab nruab nrab xim tsis siv atomic tshauv.
2. Kev cuam tshuam ntawm cov txheej txheem sib txawv ntawm adhesion
Cov txheej txheem ziab sib txawv thiab cov txheej txheem tshem tawm plua plav tau siv los tshawb xyuas qhov adhesion ntawm primer thiab nruab nrab txheej.
Txawm hais tias atomic tshauv yog nws tus kheej ziab los yog ziab, qhuav sib tsoo los yog dej sib tsoo, tsuav yog cov electrophoretic primer yog sanded los yog cov xim ntawm electrophoretic yog wiped huv si nrog ib tug thinner, thiab cov hmoov av tom qab atomic tshauv polishing yog kiag li tshem tawm. yuav tsis cuam tshuam qhov adhesion ntawm nruab nrab txheej thiab primer, thiab qhov adhesion ntawm nruab nrab txheej thiab primer tuaj yeem ncav cuag 0 ~ 1 qib.
3. Kho cov txheej txheem txheej txheem ntawm atomic tshauv kom tshem tawm cov txheej txheem primer sib tsoo thiab cov txheej txheem hnyav
Txhawm rau ua kom yooj yim txheej txheem txheej txheem thiab txo kev tsim muaj kuab paug, los ntawm kev txhim kho ntawm atomic tshauv ntau lawm technology, cov txheej txheem ntawm non-polishing primer thiab hnyav rubbing yog saws, rau lub hom phiaj no, resin ntau lawm formula thiab txheej txheem ntawm atomic tshauv yog kho, thiab ib tug loj tus naj npawb ntawm cov fillers raug soj ntsuam thiab sib tov. Lub sab sauv ntawm lub electrophoretic primer phaj yog coated nrog atomic tshauv, thiab lub sij hawm pib los ntawm ashing, thiab tom qab muab tso rau ntawm chav tsev kub rau 20min, tus qauv yog muab tso rau hauv ib lub qhov cub nrog qhov kub thiab txias ntawm 140 degree rau 30min thiab coj tawm, thiab tom qab ntawd lub atomic tshauv saum npoo yog polished nrog 320 # dej xuab zeb, yog li cov tsim atomic tshauv plua plav slurry ntws nrog dej mus rau saum npoo ntawm electrophoretic primer uas tsis coated nrog atomic tshauv. Cia kom qhuav ntawm chav tsev kub thiab so tawm ntawm qhov chaw ntawm cov plua plav. Qhov saum npoo ntawm cov qauv yog txau thiab muab tso rau hauv qhov cub 140 degree ntawm qhov kub thiab txias rau 30min. Tom qab cov qauv muab tso rau hauv chav tsev kub rau 60 min, qhov adhesion yog kuaj pom nrog tus sau ntawv.
Cov kev sim qhia tau hais tias qhov adhesion ntawm nruab nrab txheej thiab cov primer tuaj yeem txhim kho los ntawm kev kho cov qauv ntawm atomic tshauv, kom cov plua plav hauv paus tsis cuam tshuam rau adhesion. Yog tias cov hmoov av tom qab kev sib tsoo ntawm atomic tshauv tsis cuam tshuam rau qhov adhesion ntawm nruab nrab txheej thiab primer, uas yog, adhesion ntawm nruab nrab txheej thiab primer ncav cuag 0 ~ 1 qib, ib los yog ob hom raw khoom. yuav tsum tau muab tshem tawm ntawm atomic tshauv.
Qhov xwm txheej ntawm dej milling thiab pleev xim tom qab atomic tshauv yog nws tus kheej qhuav thiab cov dej milling thiab pleev xim tom qab kub kub ci ntawm atomic tshauv yog tib yam, uas yog, lub ntuj curing thiab ci ntawm atomic tshauv muaj tib lub txiaj ntsig ntawm adhesion ntawm electrophoretic primer thiab nruab nrab txheej.
Yog hais tias electrophoretic primer yog sanded los yog nto ntawm cov xim electrophoretic yog wiped nrog ib tug thinner, txawm yog hais tias lub lag luam muaj atomic tshauv siv, cov plua plav tom qab atomic tshauv polishing yuav tsis cuam tshuam qhov adhesion ntawm nruab nrab lub tsho tiv no thiab primer, uas yog. , adhesion ntawm nruab nrab lub tsho tiv no thiab cov primer tseem tuaj yeem ncav cuag 0 ~ 1 qib.
