Cov txheej txheem ntws ntawm cov tshuaj tsim cov iav frosted yog raws li nram no:
(1) Kev ntxuav thiab ziab: Ua ntej, ntxuav lub iav tiaj tus uas yuav tsum tau ua kom tshem tawm cov plua plav thiab stains, thiab tom qab ntawd qhuav;
(2) Hoisting: Muab cov iav uas huv thiab qhuav qhuav rau ntawm lub hanger, pad qhov kev sib cuag ntawm lub hanger nrog lub iav nrog roj hmab bracket, unload lub iav vertically, thiab tawm ib qho kev ncua deb ntawm lub iav thiab iav. Tom qab ntawd nqa nrog lub crane;
(3) Corrosion: Muab cov iav tiaj tiaj ua ke nrog lub hanger rau hauv lub thawv corrosion nrog lub crane, tsau lub iav nrog cov tshuaj corrosion, thiab lub sij hawm corrosion yog 5-10 feeb;
(4) Softening: Tom qab drenching tawm cov residual kua, ib txheej ntawm residue yog txuas mus rau saum npoo ntawm cov kua qaub-ntxuav iav, muab tso rau hauv ib tug softening lub thawv rau softening, soak lub iav nrog cov pa softening kua, thiab tshem tawm cov residue rau { {2}} feeb rau lub sijhawm softening;
(5) Kev Tu: Cov kua qaub-ntxuav frosted iav muaj ntau cov tshuaj lom neeg nyob rau hauv cov txheej txheem ntawm corrosion thiab softening. Nws yog ib qho tsim nyog yuav tsum muab cov kua qaub-ntxuav iav rau hauv lub tshuab ntxhua khaub ncaws los ntxuav nws;
(6) Kev ziab: Cov kua qaub-ntxuav frosted iav tom qab ntxuav kawg yog muab tso rau hauv chav ziab kom qhuav.
