Txhawm rau tiv thaiv kev khawb ntawm cov npoo polished ntawm iav thaum ua haujlwm, kev thauj mus los lossis kev teeb tsa, kev tswj hwm yuav tsum tau ua los ntawm ntau qhov sib txuas xws li xaiv cov khoom siv, kev tswj cov txheej txheem thiab kev tiv thaiv kev ua haujlwm.
1. Kev tiv thaiv thaum ua haujlwm
(1) Optimization ntawm polishing txheej txheem
Xaiv cov zoo- cov log sib tsoo zoo
Nyob rau theem kawg polishing, pob zeb diamond sib tsoo lub log nrog qhov loj me ntawm Ntau dua lossis sib npaug ntawm 3000 mesh lossis cerium oxide polishing log yog siv los txo qhov roughness ntawm qhov chaw (Ra tsawg dua lossis sib npaug li 0.01μm).
Kev tswj cov coolant
Siv ph- nruab nrab siab txias txias (xws li ethylene glycol tov uas muaj xeb inhibitor) los tiv thaiv cov seem ntawm corroding cov npoo.
Polishing parameter tswj
Tuav lub nrawm nrawm ntawm 15 mus rau 25m / s thiab pub tshaj tawm tsis pub tshaj 0.5mm / min los tiv thaiv microcracks los ntawm overheating.
(2) Ntug ua tshuab
Chamfer tsim
Thaum ua tiav, cia lub chamfer ntawm 0.3 txog 0.5mm × 45℃kom txo tau qhov kev pheej hmoo ntawm kev sib cuag nrog cov npoo ntse thiab cov fab.
Secondary zoo polishing
Manually re- polished polished npoo nrog ib tug mos mos log thiab cerium oxide hmoov kom tshem tawm tej burrs.
2. Kev tuav thiab kev tiv thaiv cia
(1) Tiv thaiv qhov chaw sib cais
Kev xaiv cov khoom siv cushion
Qhwv cov npoo nrog EVA ua npuas ncauj pads (thickness Ntau dua los yog sib npaug li 5 hli) los yog silicone tiv thaiv cov ntaub ntawv los tiv thaiv kev sib cuag ncaj qha nrog hlau lossis khoom tawv.
Vertical cia
Lub iav yog tilted ntawm 5℃mus rau 10℃thiab muab tso rau ntawm A-zoo li tus ncej, nrog txhua daim sib cais los ntawm A PE cais (0.2 hli tuab).
(2) Cov cuab yeej txhim kho
Suction khob tiv thaiv
Txuas polyurethane tsis nco qab (Shore hardness 60A) rau qhov sib cuag ntawm lub tshuab nqus tsev nqus khob.
Hoisting txoj kev npaj
Siv cov nylon slings es tsis txhob steel hlau ropes, nrog ib tug sling dav ntawm tsis tsawg tshaj li 50 hli kom tsis txhob muaj kev nyuaj siab hauv zos.
3. Kev tiv thaiv txheej txheem installation
(1) Framework ua ntej
Qhov qhib qhov ntxuav
Tshuab tawm cov hlau shavings hauv qhov profile zawj nrog compressed cua. Yog tias tsim nyog, lo rau U-zoo li tus PE ntug daim kab xev.
Kev tsim cov nplaum nplaum
Ua ntej siv qhov nruab nrab silicone sealant (xws li Dow Corning 791), ces muab nws tso rau hauv lub khob kom tsis txhob muaj kev sib txhuam nyuaj.
(2) Cov qauv kev ua haujlwm
"Xero-hu rau" installation
Siv cov lus qhia rub tawm los pab nkag rau hauv qhov zawj. Tsis txhob rub tus ntug ntawm iav.
Kev tiv thaiv neeg ua haujlwm
Tus neeg teb xov tooj yuav tsum hnav cov hnab looj tes huv si (cov hnab looj tes nrog cov xuab zeb yog txwv nruj).
4. Kev soj ntsuam zoo thiab kev saib xyuas zoo
Kev kuaj xyuas txoj kev
Tshawb xyuas cov npoo nrog LED sab teeb ntsuas (illuminance Ntau dua lossis sib npaug li 1000lux). Yog tias qhov khawb qhov tob tshaj 0.05mm, yuav tsum tau ua dua tshiab.
Kev saib xyuas tsis tu ncua
Thaum khaws cia rau ntau tshaj 30 hnub, rov xyuas cov npoo thiab siv tshuaj tiv thaiv - oxidation wax (xws li Renolit Gleitmittel).
5. Cov khoom siv lwm txoj kev daws teeb meem (High-Txoj kev xav tau)
Tus kheej- kho cov txheej txheem
Txau UV- kho nano- txheej (xws li 3M Scotchgard) ntawm ntug polished tuaj yeem kho cov khawb me me.
Ua ntej- nruab ntug tiv thaiv
Yuav cov iav tiav nrog PVC ntug qhwv ncaj qha (xws li Saint-Gobain's Edgetech series).
