1.Rust tiv thaiv lub sij hawm yuav tsum tau?
Luv-term (<3 months): Such as in-plant turnover, domestic short-distance transportation.
Nruab nrab-lub sij hawm (3-12 lub hlis): Xws li cov khoom siv hauv tsev, kev faib khoom.
Long-term (>1 xyoo): Xws li kev xa tawm hiav txwv freight, ntev - cov khoom lag luam tawm tswv yim.
2.Cov kauj ruam tom ntej yog dab tsi?
Puas yuav tsum tau ntxuav? Hom tshuaj ntxuav dab tsi (alkaline, hnyav, dej-raws li)?
Kev ua ncaj qha? Xws li direct stamping los yog dabtsi yog khoov (yuav tsum tau ib tug uniform roj zaj duab xis uas tsis lo rau pwm).
Vuam? Yuav tsum tsis tshua muaj flash point thiab tsis tshua muaj volatility residue los tiv thaiv weld porosity thiab fumes.
Txheej (tshuaj pleev xim, electrophoresis)? Yuav tsum tau tshem tawm tag nrho los ntawm pretreatment (phosphating, silanizing) tsis cuam tshuam rau txheej adhesion.
Platinum txheej? Yuav tsum tau huv heev thiab tsis muaj residue.
3.Dab tsi yog qhov yuav tsum tau ua rau qhov chaw cia khoom thiab kev thauj mus los?
Sab Hauv Tsev / Sab Nraud: Sab nraum zoov daim ntaub ntawv yuav tsum muaj zog UV tiv taus thiab huab cua tsis kam.
Ntug hiav txwv / High Humidity / Loj Kub Qhov Sib txawv: Yuav tsum muaj kev tiv thaiv siab rau ntsev tsuag thiab tiv thaiv xeb hauv cov av noo siab.
Kev ntim khoom: nthuav tawm, ib zaug -cap/lined nrog xeb- ntawv pov thawj, tag nrho kaw (piv txwv li, stretch film ntim). Kev ntim khoom zoo dua tso cai rau txo qis me ntsis ntawm cov xeb tsis huv - tiv thaiv cov roj.
4.Dab tsi yog ib puag ncig thiab kev nyab xeeb kev cai?
Cov ntxhiab tsw: cuam tshuam rau lub tsev khaws khoom lossis cov neeg ua haujlwm hauv chaw ua haujlwm.
Flash Point: Kev ntsuas kev nyab xeeb hluav taws ntsig txog kev khaws cia thiab kev thauj mus los.
Environmental Regulations: Muaj cov khoom txwv (xws li nitrites, hnyav hlau, qee yam chlorides).
Kev Kho Kom Zoo: Kev kho yooj yim.
5.Dab tsi yog hom roj hauv paus?
Cov kuab tshuaj- hom diluted: ceev- ziab, tsim cov zaj duab xis qhuav lossis mos, tiv thaiv xeb zoo, tshem tawm yooj yim, tab sis evaporates sai, muaj ntxhiab tsw, thiab yog nplaim taws. Haum rau luv luv -lub sij hawm tiv thaiv xeb thiab precision qhov yuav tsum tau ntxuav tom qab.
Lubricating roj hom: xeb inhibitors yog ntxiv rau cov roj hauv paus (cov roj ntxhia, roj hluavtaws) los tsim cov roj zaj duab xis. Classified los ntawm viscosity:
Tsawg viscosity: nyias txheej, yooj yim tshem tawm, haum rau luv luv - tiv thaiv xeb thiab ncaj qha machining.
Nruab nrab-siab viscosity: tuab roj zaj duab xis, ntev tiv thaiv xeb, tab sis tej zaum yuav cuam tshuam rau tom ntej tu los yog machining.
Roj hom: Cov roj nplaum tuab yog tsim nrog qhov sib ntxiv ntawm cov thickener, muab lub sijhawm tiv thaiv xeb ntev tshaj plaws, tab sis nyuaj rau thov thiab tshem tawm. Feem ntau siv rau ntev - lub sij hawm cia, tsis haum rau txias - dov coils yuav tsum tau machining ncaj qha.
