Cov yam ntxwv ntawm cov nplaum daim ntawv lo rau lub ntsej muag cov ntaub ntawv cuam tshuam li cas rau tuag- txiav zoo?
Siab- cov ntaub ntawv nplaum nplaum (PSA) yog ib hom khoom siv sib xyaw, thiab tuag- txiav yog txawv ntawm qhov tuag- txiav cov khoom luam tawm ib txwm muaj. Piv txwv li, tuag- txiav daim ntawv cuam tshuam nrog kev txiav tag nrho cov khoom; whereas rau PSA cov ntaub ntawv, tuag- txiav tsuas yog txiav los ntawm lub ntsej muag cov khoom thiab cov nplaum txheej, tawm hauv daim ntawv thaub qab thiab nws cov txheej silicone tsis zoo. Qhov no ua rau tuag- daim ntawv txiav raug ua raws li daim ntawv rov qab siv tom qab. Thaum txiav txim siab seb daim ntawv lo puas tuaj yeem raug tuag-txiav, txawm tias cov npoo yog du thiab zoo huv si, lossis seb daim ntawv rov qab yog tho los yog cov npoo ntxhib tseem nyob, cov yam ntxwv ntawm PSA daim ntawv lo rau lub ntsej muag khoom ua lub luag haujlwm tseem ceeb heev.
Kab lus no piav qhia txog kev sib raug zoo ntawm cov yam ntxwv ntawm PSA daim ntawv lo rau lub ntsej muag cov ntaub ntawv thiab tuag- txiav los ntawm qhov kev xav ntawm kev faib tawm thiab cov yam ntxwv ntawm PSA daim ntawv lo lub ntsej muag cov ntaub ntawv, nrog rau yuav ua li cas txhim kho qhov tuag- txheej txheem txiav, rau tus nyeem ntawv siv.
Kev faib tawm thiab cov yam ntxwv ntawm PSA Label Face Materials
Hauv thaj chaw ntawm PSA cov ntawv lo, cov ntaub ntawv siv ntsej muag feem ntau tuaj yeem muab faib ua ob pawg: cov ntaub ntawv ntsej muag thiab cov ntaub ntawv ntsej muag.
01Daim ntawv Facestock
Daim ntawv nplaum nplaum yog tsim rau ntau txoj kev luam ntawv, yooj yim los tsim kua muag, breathable, thiab ntau haum rau siv nyob rau hauv qhuav ib puag ncig. Cov ntaub ntawv ntawv lawv tus kheej tsis muaj dej tsis zoo lossis roj- cov khoom pov thawj, tab sis cov txheej txheem xws li lamination tuaj yeem ua rau ntawv muaj qee yam dej thiab roj. Cov ntawv feem ntau suav nrog cov ntawv coated, daim duab kos duab, ntawv holographic, ntawv txhuas ntawv ci, ntawv ruaj ntseg, ntawv kraft, ntawv textured, thiab lwm yam.
Ntawm lawv, daim duab kos duab muaj qhov zoo nkauj zoo nkauj, cov xim muaj zog, thiab kev luam ntawv zoo, tab sis qhov kev ntxhib los mos yog qhov tsis zoo thiab cov npoo yuav puas los yog frayed thaum tuag- txiav; kraft daim ntawv muaj lub zog siab thiab tawv, yog hnav- tiv taus, tab sis muaj qhov ntxhib saum npoo, muaj zog number case nqus, thiab tuaj yeem tsim cov ntawv seem thaum tuag- txiav, thaiv qhov tuag thiab cuam tshuam rau kev txiav raug.
02
Zaj duab xis Facestock
Cov ntaub ntawv zaj duab xis muaj cov dej zoo thiab cov roj ua haujlwm, du nto, thiab yooj yim luam tawm. Lawv muaj kev tiv thaiv huab cua siab thiab tiv thaiv corrosion, ua kom ntev - lub sij hawm ruaj khov thiab meej meej ntawm cov ntawv, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv siab - kawg thiab ntev - cov ntawv khaws cia. Cov yeeb yaj kiab feem ntau suav nrog PET (Polyethylene Terephthalate), PP (Polypropylene), PE (Polyethylene), thiab lwm yam.
Ntawm lawv, PET facestock muaj cov tshuaj tiv thaiv zoo heev, kub tsis kam, thiab cov khoom siv dag zog, nrog kev ruaj ntseg zoo, thiab tsis yooj yim deformed thaum tuag- txiav, tab sis vim nws qhov siab hardness, nws ua rau hnav ntau dua rau cov tuag- txiav cuab yeej; PP facestock yog mos, saj zawg zog, thiab muaj zoo fold kuj, tab sis nws yog nquag ua raws li thaum lub sij hawm tuag- txiav, ua kom tshem tawm cov khib nyiab nyuaj; PE facestock has low surface tension and poor adhesiveness, requiring special treatment after die-cutting to ensure label adhesion.
Kev cuam tshuam tshwj xeeb ntawm Facestock Properties ntawm Tuag-Kev Txiav Zoo
Lub cev thiab tshuaj lom neeg cov khoom ntawm facestocks cuam tshuam tuag-txiav zoo hauv ntau yam.
01Thickness thiab Uniformity
Lub thickness ntawm lub ntsej muag khoom ncaj qha cuam tshuam qhov tob ntawm kev tuag txiav. Lub thicker lub ntsej muag khoom, qhov yooj yim dua nws yog tuag txiav. Hloov pauv, cov khoom siv thinner, qhov ntau dua nws yog txiav los ntawm daim ntawv thaub qab. Yog li ntawd, lub thickness ntawm lub ntsej muag khoom ncaj qha cuam tshuam rau kev xaiv ntawm tuag- txiav cov cuab yeej thiab qhov chaw ntawm tuag- txiav siab. Piv txwv li, thaum tuag txiav PET lub ntsej muag cov khoom nrog lub thickness ntawm 0.1 hli, nws yog ib qhov tsim nyog los xaiv ib tug tuag- txiav hniav nrog ib tug me me lub kaum sab xis thiab siab dua hardness, thiab precisely tswj cov tuag- txiav siab kom txiav zoo.
02
Flexibility thiab Hardness
Qhov yooj thiab hardness ntawm lub ntsej muag cov ntaub ntawv txiav txim nws deformation thaum lub sij hawm tuag- txheej txheem txiav thiab hnav ntawm cov cuab yeej. Piv txwv li, qhov yooj yim ntawm PP lub ntsej muag cov khoom ua rau nws yooj yim rau cov ntawv nrog cov duab nyuaj kom muaj cov npoo tsis sib xws thaum txiav tuag, thaum lub siab tawv ntawm PET lub ntsej muag ua rau cov npoo ntawm tuag- txiav cov hniav kom dull sai dua, yuav tsum tau hloov cov hniav ntau zaus.
03
Nto Smoothness
Qhov saum npoo du ntawm cov khoom siv lub ntsej muag cuam tshuam rau kev sib txhuam thiab kev tshem tawm pov tseg thaum lub sij hawm txiav tuag. Cov ntaub ntawv lub ntsej muag du, xws li cov ntawv coated, muaj kev sib txhuam tsawg dua nrog cov cuab yeej txiav thaum txiav tuag, ua rau cov txheej txheem txiav tau yooj yim, tab sis tuaj yeem ua rau muaj teeb meem hauv kev sib cais cov ntawv los ntawm cov ntawv thaub qab. Rough- cov ntaub ntawv ntawm lub ntsej muag, xws li cov ntawv kraft, pab tshem tawm cov khib nyiab, tab sis tuaj yeem tsim cov khoom khib nyiab thaum txiav, cuam tshuam rau tuag- txiav cov khoom zoo thiab cov khoom siv huv.
Optimizing Tuag-Txiav cov txheej txheem raws li lub ntsej muag khoom yam ntxwv
Txhawm rau hais txog qhov cuam tshuam ntawm cov khoom siv ntsej muag sib txawv ntawm kev tuag-txiav zoo, qhov tuag- txheej txheem txiav yuav tsum tau ua kom zoo raws li qhov tshwj xeeb ntawm cov khoom siv lub ntsej muag.
01
Kev xaiv cuab yeej
Xaiv cov khoom tsim nyog- txiav cov cuab yeej raws li qhov hardness thiab thickness ntawm cov khoom nto. Rau ntawv-raws li qhov chaw, carbon steel riam tuaj yeem xaiv, raws li lawv qhov ntse thiab hnav tsis kam tuaj yeem ua tau raws li qhov dav dav tuag- txiav cov kev cai rau cov ntaub ntawv. Rau zaj duab xis-raws li qhov chaw, tawv thiab ntse dua carbide los yog tungsten steel riam yuav tsum tau xaiv los xyuas kom meej txiav precision thiab cov cuab yeej siv tau ntev. Tsis tas li ntawd, thaum txiav qhov chaw nrog kev yooj yim dua, lub kaum sab xis tuaj yeem txo qis me ntsis los txhim kho cov txiaj ntsig txiav.
02
Tuag-Txiav siab thiab ceev
Kev tswj kom raug tuag-txiav siab thiab ceev yog qhov tseem ceeb kom ntseeg tau tias tuag- txiav zoo. Piv txwv li, thaum tuag-txiav PET nto, tuag- txiav siab tuaj yeem teem caij ntawm 8-10 MPa, thiab tuag- txiav ceev tswj ntawm 20-30 m / min kom ua tiav kev tuag zoo- txiav cov txiaj ntsig.
03
Kev tshem tawm pov tseg
Txais cov txheej txheem tshem tawm cov khoom pov tseg raws li cov khoom pov tseg ntawm cov khoom sib txawv. Rau cov yeeb yaj kiab-raws li qhov chaw uas yooj yim lo, cov txheej uas tsis yog - nplaum tuaj yeem siv rau cov menyuam tshem tawm cov khib nyiab los txhim kho kev tshem tawm pov tseg. Rau daim ntawv- raws li qhov chaw uas yooj yim tsim cov khib nyiab, lub tshuab nqus tsev tuaj yeem muab ntxiv kom tshem tawm cov ntawv pov tseg sai li sai tau thaum tuag- txiav.
Hauv cov ntsiab lus, hauv kev tsim khoom tiag tiag, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas qhov sib haum ntawm cov yam ntxwv ntawm cov khoom saum npoo thiab tuag- txiav cov txheej txheem thiab txuas ntxiv cov kev paub dhau los txhawm rau txhim kho qhov zoo thiab ua haujlwm ntawm cov ntawv sau.
