Yob zaj duab xis, cov khoom siv ua yeeb yaj kiab hloov pauv tau muab rau hauv daim ntawv yob, yog siv dav hauv kev ntim khoom, luam ntawv, kev tsim kho, thiab cov khoom siv niaj hnub. Nws cov kev ua haujlwm ruaj khov thiab kev pabcuam lub neej feem ntau nyob ntawm kev khaws cia thiab kev saib xyuas txhua hnub.Kev saib xyuas kev tshawb fawb tuaj yeem tiv thaiv cov yeeb yaj kiab los ntawm absorbing noo noo, deforming, ua paug, thiab muaj kev ua tau zoo degradation, kom ntseeg tau tias nws tseem nyob rau hauv qhov zoo thaum lub sij hawm tom ntej thiab siv.
Cia ib puag ncig yog qhov tseem ceeb hauv kev kho cov yeeb yaj kiab yob. Yob zaj duab xis yuav tsum muab cia rau hauv qhov chaw txias, qhuav, thiab zoo -ventilated warehouse. Qhov zoo tshaj plaws ambient kub yog tswj ntawm 15℃thiab 25 degree, thiab tus txheeb ze humidity yog tswj ntawm 40% thiab 60%. Qhov kub thiab txias ua rau kev laus ntawm cov saw hlau polymer, ua rau embrittlement lossis txo qhov gloss; high humidity yooj yim ua rau lub substrate nqus noo noo thiab nthuav los yog ua ntej - tshwm sim nyob rau hauv cov nplaum txheej, uas ua rau interlayer adhesion los yog nto haze. Nyob rau tib lub sijhawm, lub hnub ci ncaj qha thiab qhov sib thooj rau cov khoom siv hluav taws xob yuav tsum raug zam kom tsis txhob softening, deformation, lossis oxidation ntawm cov thermoplastic resin.
Txoj kev uas yob zaj duab xis muab tso rau kuj yuav tsum tau saib xyuas. Membrane rolls yuav tsum tau teem kom ruaj ntseg, horizontally los yog ntsug, nrog ib tug stacking qhov siab tsis dhau los tiv thaiv qis yob los ntawm deformed nyob rau hauv siab los yog tsim irreversible kev nyuaj siab cim. Siv cov tais tshwj xeeb lossis cov forklifts rau kev tuav kom tsis txhob rub, ntuav, lossis cuam tshuam los ntawm cov khoom tawv, uas tuaj yeem khawb cov txheej membrane, ua rau cov npoo, lossis deform lub hauv paus. Thaum tshem tawm cov yob, nws raug nquahu kom unroll nws txheej los ntawm txheej los ntawm lub nplhaib sab nraud kom tsis txhob rub tawm ntau dhau ib zaug, uas tuaj yeem ua rau tsis sib haum xeeb thiab ua rau ncab deformation lossis wrinkles.
Yog tias tsis siv daim nyias nyias tom qab qhib, qhov seem seem yuav tsum tau muab rov qab siv cov khoom siv los tiv thaiv lub hau los yog cov dej noo- pov thawj zaj duab xis, thiab xa rov qab mus rau qhov chaw cia khoom uas ua tau raws li qhov xav tau ntawm qhov kub thiab av noo kom sai li sai tau kom tsis txhob ya raws thiab plua plav nkag. Rau cov yob nrog cov txheej txheem tso tawm lossis cov txheej txheem oxidized yooj yim, lub sij hawm raug yuav tsum raug txo kom tsis txhob muaj qhov degradation ntawm qhov chaw uas tuaj yeem cuam tshuam rau kev ua haujlwm tom ntej.
Thaum siv txhua hnub, qhov tsos thiab qhov kawg -lub ntsej muag ntawm daim nyias nyias yob yuav tsum tau kuaj xyuas tsis tu ncua, ua tib zoo saib xyuas cov teeb meem xws li pwm me me, xim txawv, qhov nplaum, lossis qhov kawg ntawm lub ntsej muag. Thaum kuaj pom qhov txawv txav, qhov cuam tshuam yuav tsum raug cais tawm, qhov ua rau tshuaj ntsuam xyuas, thiab kev khaws cia lossis tuav txoj kev kho tam sim ntawd. Qhia rollers thiab nias qhov chaw ntawm cov cuab yeej ua haujlwm yuav tsum tau ua kom huv si kom tsis txhob muaj cov khoom siv los yog cov roj hloov mus rau cov yeeb yaj kiab saum npoo thiab tsim cov teeb meem uas nyuaj rau tshem tawm.
Tsis tas li ntawd, kev saib xyuas yuav tsum tau ua rau ntau hom yob zaj duab xis sib txawv me ntsis. Piv txwv li, polyester (PET) raws li yob zaj duab xis yog rhiab rau cov av noo thiab xav tau kev saib xyuas ntxiv rau kev tiv thaiv ya raws; polyethylene (PE) yob zaj duab xis yog raug rau qis -kub embrittlement, thiab cia kub yuav tsum tsis txhob qis dhau rau lub caij ntuj no; Composite functional yob zaj duab xis muaj ntau txheej txheej thiab yuav tsum tsis txhob sib cuag nrog cov organic solvents los yog corrosive chemicals los tiv thaiv kev puas tsuaj rau cov txheej txheem ua haujlwm.
Hauv cov ntsiab lus, kev saib xyuas cov yeeb yaj kiab yob yog qhov tseem ceeb thoob plaws hauv tag nrho cov txheej txheem ntawm kev khaws cia, tuav, qhib, thiab siv, yuav tsum tau kaw - lub voj voog kev tswj hwm kev tswj hwm ib puag ncig, cov txheej txheem ua haujlwm, thiab kev tshuaj xyuas tsis tu ncua. Kev nruj nruj rau cov kev ntsuas no tuaj yeem ua rau qhov kev ncua sij hawm ntawm cov khoom laus, tswj kev ruaj ntseg ntawm lub cev thiab cov khoom siv kho qhov muag, thiab muab kev ruaj ntseg ruaj ntseg rau siab - kev ua haujlwm zoo thiab kev siv.
