Qhov teeb meem ntawm kaum thiab tawg thaum lub sij hawm tuag-txiav, kev sib txuas mailer shipping thawv, thiab cov txheej txheem ntim cov thawv xim feem ntau teeb meem ntau lub ntim thiab luam ntawv lag luam.Tom ntej no, cia peb saib cov txheej txheem tuav ntawm cov neeg ua haujlwm laus rau cov teeb meem zoo li no.cov ntaub ntawv luam yeeb
1. Lub siab tsis zoo ua rau tawg
1.1 Muaj cov khoom txawv teb chaws nyob rau hauv qhov indentation zawj ntawm lub phaj hauv qab, ua rau antsence siab thaum txiav tuag.Qhov no yog ib qho ua rau muaj kev puas tsuaj ntawm kev tawg hauv kev tsim khoom.Nws tuaj yeem ua rau tag nrho cov kab tsaus nti tawg, ua rau cov khoom seem.vape ntim
1.2 Runout, uas txhais tau hais tias qhov tuag-txiav los yog hauv qab phaj yog positioned kom cov hlau hlau ntog rau sab nraum lub indentation zawj.Qhov tawg tshwm sim los ntawm qhov laj thawj no feem ntau yog tsom rau ntawm cov kab tsaus nti hauv tib qho kev taw qhia, uas yog vim tsis muaj nruj haum ntawm kev txiav los yog indentation riam thiab cov qauv ntoo, uas ua rau kev sib txawv ntawm qhov siab.
Kev xaiv ntawm steel hlau thickness thiab indentation groove dav tsis phim cov ntaub ntawv.Raws li qhov yuav tsum tau ua ntawm cov txheej txheem tuag-txiav, cov hlau sib txawv yuav tsum tau siv rau ntau hom ntawv, nrog rau cov thicknesses sib txawv ntawm lub hauv paus daim hlau thiab qhov dav ntawm cov kab sib txawv.Yog tias tsis sib xws, nws yooj yim ua rau cov kab zais kom tawg.hlau nplaum box
2. Cracking tshwm sim los ntawm kev tuag-txiav phaj txheej txheem
2.1 Kev tuav tsis raug ntawm txoj haujlwm steel hlau lossis burrs sab laug thaum txiav cov hlau hlau thaum lub sij hawm tsim cov phaj tuag.Yog tias cov khoom tau raug kho saum npoo hauv kev tuag txiav, xws li lamination.Burrs sab laug ntawm cov hlau xaim thaum txiav tuag tuaj yeem ua rau lub zog tensile ntawm zaj duab xis nto, thiab zaj duab xis tsis tuaj yeem tiv taus lub zog thaum cov khoom molding, ua rau tawg.
2.2 Cov riam hlau thiab hlau ntawm txoj kab tsaus nti muaj cov hniav thiab qhov sib txuas.Vim lub unevenness ntawm lub interface, tearing yuav tshwm sim thaum txiav tuag.
Thaum lub sponge ncoo ntawm hlau nias riam tsis nyob rau hauv qhov tsim nyog, cov hlau nias yuav tawg, thiab deformation thiab kev puas tsuaj ntawm cov hlau nias riam tuaj yeem ua rau cov hlau nias tawg.
Puas yog kev sib xyaw ntawm riam thiab hlau ntawm riam pwm tsim nyog.Tshwj xeeb tshaj yog thaum tus tsim tsis xav txog qhov tuab ntawm daim ntawv, qhov sib tshooj ntawm cov riam thiab cov kab tsis tuaj yeem zam tau zoo, thiab kev cuam tshuam tshwm sim thaum molding, uas ua rau muaj zog ntau dhau ntawm qhov tam sim no thiab qhov tshwm sim ntawm kev tawg.
3. Cov teeb meem zoo ntawm cov khoom
3.1 Yog tias cov ntsiab lus dej ntawm daim ntawv tsawg dhau, daim ntawv yuav nkig.Qhov tshwm sim no feem ntau tshwm sim nyob rau lub caij ntuj no, vim huab cua qhuav thiab txias, thiab cov txheeb ze av noo nyob rau hauv cov huab cua tsis tshua muaj, uas ncaj qha cuam tshuam rau cov dej noo ntawm cov duab los qhia, ua rau cov duab los qhia tawg tom qab nias.Feem ntau, cov dej noo ntawm cov ntawv hauv paus yog tswj nyob rau hauv qhov txwv siab tshaj (nruab nrab ntawm 8% -14%);
3.2 Cov ntaub ntawv lamination: Biaxially stretched polypropylene zaj duab xis muaj qhov sib txawv me ntsis, ua rau txo qis zog tensile.Lamination yog ib txoj kev kho saum npoo rau daim ntawv, feem ntau yog ua los ntawm BOPP zaj duab xis.Yog tias BOPP zaj duab xis puas lawm ua ntej kev txiav tuag, nws yuav ua rau BOPP zaj duab xis tsis tuaj yeem tiv taus lub zog thiab tawg thaum khoov tom qab txiav tuag.Lub bursting ntawm zaj duab xis tsuas yog tshwm sim nyob rau hauv cov zaj duab xis txheej, thiab raws li lub zog taw tes nce, nws yuav ncua raws li bursting kev taw qhia.Cov txheej hauv qab ntawm daim ntawv tsis tawg, qhia tias nws tsis cuam tshuam nrog daim ntawv.Yog tias cov yeeb yaj kiab tsis tawg thiab daim ntawv tau tawg lawm, nws tsis cuam tshuam nrog cov yeeb yaj kiab thiab muaj teeb meem ntawm daim ntawv.
3.3 Paper orientation tsis raug.Thaum tuag-txiav, yog hais tias cov kev taw qhia ntawm indentation steel hlau yog perpendicular mus rau cov kev taw qhia ntawm daim ntawv fibers, uas yuav ua rau radial puas rau daim ntawv fibers, cov kab tsaus nti yog nquag khoov, sib sau zoo, thiab lub kaum sab xis yog me me;Yog hais tias lub indented steel hlau nyob rau hauv parallel mus rau fiber ntau cov kev taw qhia ntawm daim ntawv thiab daim ntawv tsis puas horizontally, lub tsaus hlau tsis yooj yim khoov thiab tsim rau hauv ib tug rounded kaum nrog ib tug loj lub kaum sab xis, uas muaj ib tug muaj zog pab txhawb nqa nyob rau hauv lub txheej txheej. ntawm daim ntawv thiab nws nquag tawg.Cov kev taw qhia ntawm daim ntawv muaj kev cuam tshuam me ntsis rau kev tuag ntawm ib daim ntawv cov khoom, tab sis nws tsis yooj yim rau tawg kab vim tsis zoo molding.Txawm li cas los xij, nws muaj kev cuam tshuam loj heev rau cov khoom siv daim npav.Yog tias tsis ua haujlwm zoo, tsis yog tsuas yog molding tsis zoo, tab sis nws kuj yog ib qho yooj yim rau tawg kab.Qhov laj thawj tseem ceeb yog tias cov kab tsaus nti sib npaug rau cov ntawv nplej tawg kab hauv ntau txoj haujlwm, thaum lwm qhov kev taw qhia tsis.
3.4 Corrugation configuration siab dhau lawm.Lub bursting zog thiab transverse nplhaib compression zog ntawm lub hauv paus ntawv yog ib qho ntawm feem cuam tshuam.Yog tias qhov folding tsis kam ntawm cov ntawv sab hauv qis dhau, nws tuaj yeem ua rau tawg yooj yim.
3.5 Cov pwm tau siv ntev dhau lawm.Tom qab siv lub sijhawm ntev ntawm cov phaj txiav hauv kev txiav tuag, cov hlau nias riam yuav xoob, ua rau cov hlau nias khawm kom thaws thaum lub sij hawm txiav cov txheej txheem tuag, ua rau cov duab los qhia xov hlau tawg.Vim yog siv lub sijhawm ntev ntawm cov roj hmab ncoo, qhov siab tsis sib xws ntawm lub ncoo ua rau cov kab siab tawg.
