Hauv ntau yam kev lag luam tsim khoom, cov roj hmab dov yog ib qho khoom siv uas muaj nyob thoob plaws tab sis tseem ceeb heev. Pom muaj nyob rau hauv txhua yam los ntawm kev luam ntawv ceev ceev thiab cov tshuab laminating mus rau cov kab ua hlau thiab cov tshuab luam ntawv hauv chaw ua haujlwm, kev ua haujlwm ntawm cov roj hmab dov yuav luag tag nrho yog txiav txim siab los ntawm qhov zoo ntawm nws qhov chaw. Txawm hais tias cov menyuam yuav raug puab thiab npog nrog kev ua kom raug, Tuam Tshoj cov chaw tsim khoom ua cov menyuam, nws yog theem kawg ntawm kev ua tiav - tshwj xeeb, polishing - uas tsa cov khoom siv ua haujlwm mus rau hauv cov cuab yeej ua haujlwm siab. Lub tshuab polishing cov menyuam roj hmab yog cov khoom siv tshwj xeeb tsim rau txoj haujlwm no, cov chaw tsim khoom roj hmab dov, siv thaum tus qauv ntawm qhov roughness ntawm qhov chaw (Ra) xav tau qhov du zoo meej.
Lub Hom Phiaj: Qhov Roughness ntawm Qhov Chaw thiab Nws Cov Kev Cuam Tshuam
Qhov roughness ntawm qhov chaw tsis yog ib qho kev ntsuas zoo nkauj xwb; nws yog ib qho kev qhia txog kev ua haujlwm uas tswj hwm seb lub roller cuam tshuam li cas nrog nws ib puag ncig. Hauv cov ntawv thov xws li kev tsim khoom siv kho mob, kev tsim cov yeeb yaj kiab kho qhov muag, lossis kev luam ntawv siab, txawm tias qhov me me ntawm qhov chaw ntawm lub roller tuaj yeem ua rau muaj qhov tsis zoo loj heev.
Thaum cov lus qhia tshwj xeeb xav tau qhov roughness ntawm qhov chaw qis dua 0.2 Ra (micrometers) lossis txawm tias mus rau hauv qhov ntau ntawm sub-micron, kev sib tsoo txheem tsis txaus. Kev sib tsoo tawm ib qho kev taw qhia, matte tiav uas muaj cov ncov me me thiab hav. Lub tshuab polishing siv los ua kom cov ncov no tiaj tus, tsim kom muaj qhov chaw uas tsis yog tsuas yog du xwb tab sis kuj muaj zog dua thiab tiv taus kev nplaum ntawm cov khoom. Rau cov menyuam siv hauv cov ntawv thov silicone lossis urethane - qhov twg kev nplaum tuaj yeem ua rau lub vev tawg thaum luam ntawv lossis qhwv - qhov chaw polished ua kom muaj kev tso tawm huv thiab kev nruj tas li.
Lub Txheej Txheem: Txij Li Kev Txiav Abrasive Mus Rau Kev Kub Hnyiab Ntawm Qhov Chaw
Lub tshuab txhuam roj hmab txawv ntawm lub tshuab sib tsoo cylindrical ib txwm muaj. Thaum lub tshuab sib tsoo siv lub log sib tsoo ruaj khov thiab ceev ceev los tshem tawm cov khoom thiab ua tiav qhov loj me, lub tshuab txhuam ua haujlwm raws li lub hauv paus ntsiab lus ntawm kev sib txhuam thiab kev sib txhuam me me.
Cov tshuab txhuam niaj hnub feem ntau muaj lub txaj tshuab hnyav nrog lub taub hau thiab lub pob tw kom txhawb nqa lub log. Qhov tseem ceeb yog lub caj npab txhuam lossis lub tsheb thauj khoom, uas tuav cov khoom siv txhuam. Tsis zoo li kev sib tsoo, qhov twg lub log nyuaj dua li qhov khoom siv, roj hmab txhuam yuav tsum tau sib npaug zoo ntawm qhov ceev, siab, thiab cov xuab zeb txhuam.
Cov txheej txheem feem ntau nce mus txog ntau theem:
1. Ua Ntej Polishing (Smoothing): Pib nrog cov siv tawv lossis pob zeb uas muaj cov xuab zeb nruab nrab (feem ntau yog 400 txog 800 grit) kom tshem tawm cov cim kauv uas tshuav los ntawm cov txheej txheem sib tsoo. Theem no ua kom muaj qhov sib xws ntawm cov duab.
2. Kev Txhuam Zoo: Hloov mus rau cov yeeb yaj kiab abrasive siab (1500 txog 3000 grit) lossis cov nylon abrasives tsis-woven impregnated nrog cov khoom me me. tshuab txhuam zoo ， Nyob rau theem no, lub tshuab txo qhov Ra tus nqi ntau heev, txav mus rau qhov tiav semi-gloss.
3. Kev Ua Kom Tiav Zoo Kawg Nkaus (Kev Ua Kom Kub): Rau qhov xav tau siab tshaj plaws (kev pom tseeb lossis tus nqi Ra qis dua 1), lub tshuab yuav siv cov ntaub txhuam tshwj xeeb lossis cov ntaub mos uas muaj cov pob zeb diamond zoo heev lossis cov kua sib xyaw. Nyob rau theem no, cov txheej txheem tsawg dua yog hais txog kev tshem tawm cov khoom siv thiab ntau dua yog hais txog "kev pleev xim" ntawm qhov chaw roj hmab kom kaw cov qhov me me thiab tshem tawm cov qauv kev taw qhia tag nrho.
Cov tshuab niaj hnub no muaj cov yam ntxwv xws li cov taub hau oscillating abrasive los tiv thaiv kev tsim cov nplhaib concentric, cov tsav tsheb ceev sib txawv los tswj cov taw ntawm qhov chaw ib feeb (SFM), thiab cov cuab yeej ntsuas siab tsis siv neeg los xyuas kom meej tias muaj kev sib cuag tas li thoob plaws qhov ntev ntawm lub ntsej muag roller.
Lub Luag Haujlwm hauv Kev Ua tiav
Hauv cov txheej txheem ntawm kev tsim cov menyuam, kev txhuam yog qhov rooj vag zoo kawg. Tom qab lub menyuam raug pov, vulcanized (rau roj hmab), lossis kho (rau polyurethane), nws dhau los ntawm kev tig tsis zoo thiab tom qab ntawd kev sib tsoo kom raug kom coj nws mus rau qhov txoj kab uas hla thiab kev kam rau taper. Txawm li cas los xij, kev sib tsoo feem ntau ua haujlwm-tawv qhov chaw roj hmab lossis tsim cov qauv "chatter".
Lub tshuab polishing ua peb txoj haujlwm tseem ceeb:
· Kev Cais Geometry ntawm Cov Qauv: Thaum lub tshuab sib tsoo qhia qhov puag ncig thiab txoj kab uas hla, lub tshuab txhuam qhia qhov qauv yam tsis hloov pauv qhov geometry.
· Kev Txhuam Ntug: Rau cov menyuam uas muaj qhov txiav hauv qab lossis cov grooves, cov tshuab txhuam uas muaj peev xwm txhuam tau cov ntsej muag thiab cov npoo kom tiv thaiv cov burrs ntse uas tuaj yeem ua puas rau cov ntaub lossis cov yeeb yaj kiab rhiab heev.
· Kev Sib Xws ntawm Cov Khoom Siv: Cov elastomers sib txawv teb rau cua sov sib txawv. Cov tshuab txhuam hniav khiav ntawm qhov ceev qis dua nrog cov txheej txheem txias (cua lossis kua txias) kom tiv thaiv cov cua sov tsim los ntawm kev sib txhuam los ntawm kev o ntawm cov roj hmab lossis rhuav tshem cov polyurethane binders.
Kev Teeb tsa Tshuab thiab Kev Ua Haujlwm Tsis Siv Neeg
Qhov nyuaj ntawm lub tshuab txhuam roj hmab sib txawv ntawm daim ntawv thov.
· Cov Tshuab Txhuam Uas Siv Tes Ua: Feem ntau siv rau hauv cov khw me me lossis cov chaw kho, cov no vam khom tus neeg teb xov tooj lub peev xwm los siv cov siv tawv txhuam tes rau ntawm lub log uas tig. Txawm hais tias tus nqi tsim nyog, lawv tsis sib xws rau kev ua haujlwm raug siab.
· CNC Polishing Centers: Rau kev tsim khoom ntau lossis kev ua haujlwm siab, CNC (Computer Numerical Control) polishing centers yog tus qauv. Cov tshuab no khaws cov zaub mov tiav, hloov cov grits abrasive, thiab tswj cov linear pressure hla lub crown ntawm lub roller. Lawv yog qhov tseem ceeb rau cov rollers nrog cov profiles nyuaj (crowned, concave, lossis stepped) qhov twg kev txhuam tes yuav ua rau cov duab tsim tsis zoo.
· Cov Khoom Siv Superfinishing: Qee qhov kev ua haujlwm siv cov taub hau superfinishing uas sib xyaw cov oscillation nrog cov dej txias siab kom ua tiav cov qauv "cross-hatch", txawm hais tias rau cov iav tiav ntawm cov roj hmab, txoj kev felt-thiab-paste tseem yog tus qauv kub.
Cov Zoo thiab Cov Kev Txwv
Qhov zoo tshaj plaws ntawm kev siv lub tshuab txhuam tshwj xeeb yog qhov ua tiav ntawm qhov chaw tsis muaj qhov tsis zoo, zoo li daim iav uas txo qhov kev sib txhuam thiab ua kom muaj zog tshaj plaws. Rau cov lag luam xws li kev luam ntawv flexographic, lub menyuam txhuam polished ua kom muaj kev xa cov kua mem meej; rau laminating, nws tiv thaiv kev sib sau ua ke ntawm cov nplaum seem.
Txawm li cas los xij, muaj kev txwv. Kev txhuam yog ib qho txheej txheem rho tawm uas tshem tawm me me ntawm cov khoom. Yog tias cov roj hmab npog nyias dhau, lossis yog tias tus neeg teb xov tooj txhuam hnyav kom tshem tawm qhov tsis zoo tob, lub log txoj kab uas hla yuav poob tawm ntawm qhov kam rau siab. Ntxiv mus, tsis yog txhua cov roj hmab sib xyaw txhuam sib npaug. Cov menyuam mos durometer (qis dua 40 Shore A) yog qhov nyuaj rau txhuam, kev ua roj hmab, vim lawv feem ntau "sib sau ua ke" nyob rau hauv lub siab abrasive, thaum cov urethanes nyuaj dua thiab cov khoom sib xyaw EPDM tuaj yeem ua tiav zoo li iav.
Xaus lus
Lub tshuab txhuam roj hmab tsis yog tsuas yog ib qho cuab yeej ua tiav yooj yim xwb; nws yog tus choj ntawm kev ua haujlwm raug thiab kev ua haujlwm zoo. Nyob rau lub sijhawm uas kev kam rau siab ntawm kev tsim khoom tsawg zuj zus thiab qhov xav tau zoo nce ntxiv - tshwj xeeb tshaj yog hauv cov khoom siv hluav taws xob, kev kho mob, thiab kev ntim khoom - lub peev xwm los tswj qhov roughness ntawm qhov chaw me me yog qhov zoo dua rau kev sib tw.
Los ntawm kev sib txuas cov thev naus laus zis abrasive siab heev nrog kev tswj hwm tshuab kom meej, cov tshuab no ua kom ntseeg tau tias lub log roj hmab tsis yog tsuas yog ua tau raws li nws qhov kev qhia tshwj xeeb, tab sis ua haujlwm zoo kawg nkaus nyob rau hauv cov xwm txheej ntawm kev lag luam ceev ceev, kev lag luam siab. Txawm hais tias nws yog lub log hlau uas xav tau kev du thiab tsis xeb lossis lub log luam ntawv uas xav tau kev faib kua mem zoo meej, lub tshuab polishing muab qhov kov kawg, qhov tseem ceeb ntawm kev zoo meej.
