Yog tias muaj cov nplawm tawg ntawm lub npov tsoo, tom qab ntawd qhov chaw deformation yuav tsum xub ua kom sov nrog lub tshuab ziab plaub hau lossis lub tshuab hlawv, tab sis kom cov ntu tsis txawv.
Kauj ruam 2
Tom qab ua kom sov, rov qab lub bumper rau nws cov qauv qub, txhim kho nws thiab cia kom txias. Tom qab ntawv xuab zeb qhov chaw ntawm deformation, degrease nrog cov kuab tshuaj thiab siv ib lub putty (tshwj xeeb tshaj yog rau plastics).
Kauj ruam 3
Thaum lub putty yog qhuav, xuab zeb qhov putty nto nrog zoo sandpaper, degrease dua nrog cov kuab tshuaj thiab npog nrog tus primer. Xuab zeb rau saum npoo dua, degrease, thiab tom qab ntawd tsuas yog xim. Yog tias qhov tawg ntawm lub pob tw loj, ces nws yuav tsum muaj muag. Hauv qhov chaw uas muaj qhov tsis sib txawv, ua kev ua ntawm ntug. Lawv muaj peev xwm yuav soldered nrog ib tug dog dig soldering hlau.
Kauj ruam 4
Ntawm qhov chaw ntawm kev sib koom tes, qhov sib txawv yuav tsum yog cov khoom txhawb, ntxiv dag zog nrog hlau hlau (nyias) los yog siv cov kua nplaum thiab cov kua nplaum epoxy.
