Lub thawv xim feem ntau yog ua los ntawm ntau xim. Cov txheej txheem luam ntawv tom qab lub thawv xim qhia txog qhov zoo li cas thiab xim ntawm cov khoom, thiab muab rau cov neeg siv khoom pom kev zoo. Nws tau siv dav hauv tshuaj, tshuaj pleev ib ce thiab lwm yam lag luam thiab cov khoom ntim khoom thiab lwm yam lag luam. Tsab xov xwm no tau teeb tsa los ntawmPob khoom Shanghai Rainbowlos qhia cov ntsiab lus tseem ceeb ntawm cov txheej txheem luam ntawv tom qab lub thawv xim thiab cov teeb meem uas tshwm sim.
Lub thawv ximHais txog lub thawv ntawv tais thiab lub thawv ntawv me me corrugated ua los ntawm cardboard thiab micro corrugated cardboard. Feem ntau nws yog siv ua txoj hauv kev ntim khoom nruab nrab, nruab nrab ntawm cov ntim sab hauv thiab cov ntim sab nraud.
01 Cov txheej txheem tom qab luam ntawv
Cov txheej txheem tom qab luam tawm ntawm lub thawv xim suav nrog bronzing, oiling, UV varnish, polishing, zaj duab xis npog concave-convex, tuag-txiav thiab lwm yam txheej txheem.
02 Roj ntau dhau
Txoj cai ntawm cov txheej txheem
Lub yob ntsuas yog taw qhia thiab tig ntawm qhov ceev tas li, thiab qhov kev taw qhia tig yog qhov sib txawv ntawm lub yob txheej; Ua li no, txheej txheej ntawm qhov chaw ntawm lub menyuam txheej yog sib xws, qhov chaw luam tawm yog sib cuag nrog qhov chaw ntawm lub menyuam txheej, thiab txheej txheej yog sib npaug zos nyob rau hauv cov nyhuv ntawm cov viscosity txheej thiab cov menyuam pawg siab.
Hom thiab txoj kev ziab
Raws li hom roj, nws muaj peev xwm muab faib ua cov hom hauv qab no:
1) Cov roj dej ntau dhau
2) Roj ci ntsa iab
3) Cov roj superplastic
4) Roj txhuam ntau dhau
Txoj kev ziab roj: ziab infrared
Lus Cim: Cov khoom siv roj ob sab yuav tsum tau muab tso rau ntsug thiab ziab ua ntej lawv tuaj yeem tau txais. Vim tias cov khoom siv roj ob sab yooj yim lo.
kev xav tau kev txawj ntse
Ntxiv rau nws cov xim tsis muaj xim, ci ntsa iab, qhuav sai, tiv taus tshuaj lom neeg thiab lwm yam ntxwv, roj glazing kuj tseem yuav tsum muaj cov yam ntxwv hauv qab no:
1) Zaj duab xis no muaj pob tshab thiab tsis muaj xim hloov. Daim duab thiab cov ntawv yuav tsis hloov xim tom qab ziab. Ntxiv mus, nws yuav tsum tsis txhob hloov xim lossis daj vim raug tshav ntuj lossis siv ntev.
2) Zaj yeeb yaj kiab muaj qee yam kev tiv thaiv hnav.
3) Nws muaj qee qhov kev ywj pheej. Cov zaj duab xis ci ntsa iab uas tsim los ntawm txhua yam xim pleev xim rau ntawm qhov chaw ntawm cov ntawv luam tawm yuav tsum tswj tau qhov ywj pheej zoo kom hloov kho rau qhov yooj ywm ntawm daim ntawv lossis ntawv, thiab yuav tsis raug puas tsuaj, tawg lossis tev tawm.
4) Zaj yeeb yaj kiab no muaj kev tiv thaiv ib puag ncig zoo. Nws tsis raug tso cai hloov qhov kev ua tau zoo vim muaj kev sib cuag nrog cov kua qaub tsis muaj zog lossis cov hauv paus tsis muaj zog hauv ib puag ncig.
5) Nws muaj qee qhov kev nplaum rau ntawm qhov chaw ntawm cov khoom luam tawm. Vim yog qhov cuam tshuam ntawm qhov ceev ntawm daim duab thiab cov ntawv sau, qhov kev nplaum ntawm qhov chaw ntawm cov khoom luam tawm raug txo qis heev. Yuav kom tiv thaiv cov zaj duab qhuav kom tsis txhob tawg thiab tev tawm thaum siv tom qab ziab, nws yog qhov yuav tsum tau ua kom cov zaj duab muaj kev nplaum zoo, thiab muaj qee qhov kev nplaum rau cov kua mem thiab ntau yam khoom siv rau kev luam ntawv.
6) Kev sib npaug zoo thiab nto zaj duab xis du. Qhov nqus tau ntawm qhov chaw, du thiab ntub ntawm cov khoom luam tawm sib txawv heev. Yuav kom ua rau cov txheej ci ntsa iab ua zaj duab xis du ntawm cov khoom sib txawv, nws yog qhov yuav tsum tau ua kom cov roj ci ntsa iab muaj cov khoom sib npaug zoo thiab nto zaj duab xis du tom qab tsim zaj duab xis.
7) Yuav tsum muaj kev hloov pauv dav rau kev ua tiav tom qab nias. Xws li kev kub hnyiab thiab kev luam ntawv.
yam cuam tshuam
1) Kev ua tau zoo ntawm daim ntawv
Qhov cuam tshuam ntawm daim ntawv rau qhov zoo ntawm roj feem ntau yog pom tseeb hauv qhov du ntawm daim ntawv. Daim ntawv uas du thiab zoo muaj qhov cuam tshuam zoo kawg nkaus tom qab tau roj, thaum daim ntawv uas du thiab tsis du muaj qhov cuam tshuam tsis zoo rau roj, vim tias cov roj txhuam raug nqus los ntawm daim ntawv uas muaj qhov chaw ntxhib. Yuav kom daws tau qhov teeb meem no, yuav tsum tau siv roj ob zaug.
2) Kub
Qhov kub ntawm cov roj hla dhau yog 18-20 ℃, thiab cov roj hla dhau zoo tshaj plaws. Cov roj yooj yim khov thaum lub caij ntuj no, thiab cov roj ntawm qhov chaw ntawm cov khoom tsis sib npaug tom qab roj hla dhau
