(1) Kev tu ntau zaus: ① tom qab txhua batch ntawm ntau lawm; ② Tom qab qhov kawg ntawm txhua qhov kev hloov pauv ntawm kev tsim khoom tas mus li; ③ Ntxuav thiab tua kab mob ua ntej thiab tom qab tsim khoom; ④ Cov khoom, specification thiab batch tooj yuav tsum tau ntxuav thaum hloov; ⑤ Cov cuab yeej yuav tsum tau muab ntxuav thiab tua kab mob tom qab tu.
(2) Cov cuab yeej ntxuav: ntxuav cov ntaub ntawv tsis muaj duab, lub tshuab nqus tsev, txhuam, ntxuav lub phiab, thiab lwm yam.
(3) Cov tshuaj ntxuav thiab tshuaj tua kab mob: dej haus, dej huv, 75 feem pua ethanol.
(4) Txoj kev ntxuav: nyob rau hauv kev txiav txim ntawm disassembling ua ntej thiab ces ntxuav, sab hauv ua ntej thiab tom qab ntawd sab nraum, xoom ua ntej thiab ces tag nrho:
1) Kev tu cov kauj ruam rau kev tsim cov khoom sib txawv: ① Ntxuav cov hmoov seem hauv cov hmoov filling tshuab nrog lub tshuab nqus tsev thiab tom qab ntawd txhuam txhuam;
② Tshem tawm cov hmoov txhuam cov pas nrig, ntsuas phaj thiab cov hmoov hopper, coj mus rau chav ntxuav, yaug lawv nrog dej haus, tom qab ntawd yaug nrog dej huv, thiab muab cov ntaub so qhuav qhuav. So thiab tshuaj tua kab mob nrog daim ntaub dipped hauv 75 feem pua ethanol;
③ Cov khoom siv sib txuas ncaj qha nrog cov tshuaj yuav tsum tau muab ntxuav kom huv nrog dej huv, tom qab ntawd qhuav nrog cov ntaub so ntswg qhuav, thiab tom qab ntawd so thiab tshuaj tua kab mob nrog rags dipped hauv 75 feem pua ethanol;
④ Ntxuav lub iav tiv thaiv npog thiab cov khoom siv nto nrog dej huv; ⑤ Ntxuav lub xaib thiab dai daim ntawv teev npe "huv" tom qab dhau qhov kev tshuaj xyuas; ⑥ Sau cov ntaub ntawv tu.
2) Kev tu cov kauj ruam rau kev hloov ntau yam: Ntxiv nrog rau kev tu cov kauj ruam rau kev tsim cov khoom qub qub, cov haujlwm hauv qab no kuj yuav tsum tau ua:
① Tshem tawm cov kaus poom thiab cov tshuaj ntsiav tshuaj, coj mus rau chav tu, ntxuav lawv nrog dej huv, muab cov ntaub so qhuav qhuav, thiab so thiab tshuaj tua kab mob zui nrog cov ntaub qhwv dipped hauv 75 feem pua ethanol;
② So lub cam disc movable txhawb nqa nrog ib daim ntaub, tom qab ntawd txhuam nws ib zaug nrog dej huv, thiab tom qab ntawd qhuav nrog ib daim ntaub qhuav. Tom qab zui, txhuam thiab tshuaj tua kab mob nrog cov ntaub qhwv dipped hauv 75 feem pua ethanol.
(5) Kev ntsuam xyuas cov nyhuv tu: tag nrho lub tshuab yog du thiab huv. So txhua qhov chaw ntawm cov khoom siv nrog ib daim ntaub dawb huv, thiab yuav tsum tsis muaj stains, stains lossis residue ntawm daim ntaub.
