Xaiv cov ntaub ntawv zaj duab xis rau koj cov khoom nyuaj heev? Koj yuav nkag siab tom qab nyeem qhov no!
Nrog rau kev nrawm ntawm kev lag luam thiab kev txhim kho ntawm tib neeg kev paub txog kev tiv thaiv ib puag ncig, zaj duab xis tus kheej -cov ntaub ntawv nplaum tau tsim sai heev. Thaum xaiv cov khoom siv zaj duab xis uas tsim nyog tshaj plaws rau daim ntawv thov, tuam txhab lag luam yuav tsum xav txog ntau yam, xws li cov khoom siv, ib puag ncig daim ntawv thov, txheej txheem luam ntawv, thiab nqi.
Kab lus no yuav tsom mus rau cov khoom tseem ceeb ntawm cov yeeb yaj kiab thiab qhov zoo thiab qhov tsis zoo ntawm qee yam ntawm cov yeeb yaj kiab nrov tshaj plaws.
PART 01
Cov khoom tseem ceeb ntawm zaj duab xis
Cov khoom tseem ceeb ntawm cov ntaub ntawv zaj duab xis muaj xws li thickness, gloss, xim, haze / optical ceev, nto zog, shrinkage, tensile zog thiab elongation, kua muag kuj, thiab yooj. Txawm hais tias ntau yam ntawm cov yam ntxwv no zoo li paub, qee qhov tsim nyog tau txais kev paub ntxiv.
Lub zog saum npoo yog lub zog molecular ntawm nyias zaj duab xis substrate interacting nrog lwm yam khoom. Nws tuaj yeem qhia tau tias cov kua dej ntub dej li cas (xws li cov nplaum nplaum, inks, thiab lwm yam) nyob rau saum npoo ntawm cov khoom. Lub zog saum npoo yog ntsuas los ntawm kev ntsuas qhov ntub dej los yog kev sib cuag lub kaum ntse ntse, xws li cov tshuaj dyne nyob rau hauv cov ntaub ntawv ntawm wetting nro thiab dej nyob rau hauv cov ntaub ntawv ntawm kev sib cuag lub kaum sab xis.
Zaj duab xis shrinkage yog ib qho kev ntsuas ntawm qhov kev hloov ntawm qhov loj ntawm ib zaj duab xis thaum rhuab, feem ntau qhia raws li feem pua. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qee zaum cov yeeb yaj kiab kuj tseem pom qhov kev hloov pauv thaum nws txo qis, uas yuav ua rau tus neeg siv kawg ntawm cov khoom tsis txaus siab.
Lub zog tensile ntawm zaj duab xis hais txog qhov siab tshaj plaws uas cov yeeb yaj kiab tuaj yeem tiv taus ua ntej nws rub, hauv MPa. Lub elongation ntawm zaj duab xis thiab lub zog tensile tuaj yeem ntsuas tib lub sijhawm, thiab tom qab ntawd lub peev xwm ntawm cov yeeb yaj kiab tuaj yeem ncab yam tsis muaj kev tawg. Piv txwv li, 100% elongation txhais tau hais tias cov yeeb yaj kiab tuaj yeem ncav cuag 2 zaug nws qhov ntev ntev yam tsis muaj kev tawg.
Zaj duab xis tsim kua muag yog hais txog lub peev xwm ntawm cov ntaub ntawv zaj duab xis los tiv thaiv tsim kua muag, thiab yog ib qho tseem ceeb ntsuas ntsuas cov khoom siv ntawm cov yeeb yaj kiab zaj duab xis. Kev tiv thaiv kua muag tuaj yeem ntsuas tau ob txoj hauv kev: kev tsim kua muag thiab kev tsim kua muag. Tear pib quab yuam ntsuas lub zog uas yuav tsum tau pib tearing zaj duab xis, thaum lub kua muag nyob twj ywm ntsuas lub zog yuav tsum tau txuas ntxiv tearing cov kab nrib pleb uas twb muaj nyob rau hauv zaj duab xis.
Zaj duab xis yooj yog hais txog lub peev xwm ntawm cov ntaub ntawv zaj duab xis kom khoov, ncab thiab lwm yam deformation yam tsis muaj kev tawg thaum raug rau sab nraud. Qhov qis dua qhov yooj ntawm zaj duab xis, qhov nyuaj ntawm zaj duab xis thiab qhov nyuaj dua nws yog ua raws li qhov chaw.
Zaj duab xis haze (opacity) yog ib qho tseem ceeb parameter los ntsuas cov khoom kho qhov muag ntawm cov yeeb yaj kiab nyias, uas yog hais txog qhov feem pua ntawm lub teeb tawg tawg thiab tag nrho cov teeb pom kev sib kis hauv cov teeb pom kev sib kis uas deviates los ntawm cov kev taw qhia ntawm qhov xwm txheej ntau dua 2.5 degree. Qhov qis dua tus nqi haze, qhov ze ntawm zaj duab xis yog iav -zoo li pob tshab. Tus nqi haze ntau dua qhia tias lub teeb nkag mus rau zaj duab xis tsawg dua, piv txwv li, opacity ntau dua. Tus nqi haze muaj feem xyuam rau qhov roughness ntawm zaj duab xis los yog cov molecules sab hauv ntawm cov khoom.

Tsis tas li ntawd, nws tuaj yeem siv tau rau ob npaug -sided windows stickers hauv khw qhov rais.
PVC zaj duab xis: sab nraum zoov advertising
PVC zaj duab xis muaj nyob rau hauv tuab ntawm 2 mils mus rau 12 mils, ua rau lawv hloov tau yooj yim thiab zoo tagnrho rau cov ntawv thov uas muaj cov kab sib txuas. PVC yog cov yeeb yaj kiab zoo nkauj heev uas tuaj yeem yooj yim embossed los tsim cov ntawv tshwj xeeb thaum tseem yooj yim luam tawm.
PVC feem ntau yog huab cua- tiv taus, ua rau nws tiv taus UV rays thiab lwm yam kev mob ib puag ncig. Raws li kev txhim khu kev qha thiab ruaj khov substrate, PVC kuj yog ib qho kev xaiv nrov rau phab ntsa paintings thiab billboards. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias PVC tuaj yeem ua nkig ntawm qhov kub qis heev thiab muag muag ntawm qhov kub siab heev.
PP zaj duab xis: Consumer product label
PP zaj duab xis feem ntau muaj nyob rau hauv ntau hom: ntshiab, pob tshab matte, dawb los yog nyiaj (metallized). Zoo li PET, PP zaj duab xis yog feem ntau ncab rau hauv ob qho tib si cov lus qhia thiab tiv taus cov tshuaj lom neeg thiab tuaj yeem cuam tshuam nrog ntau cov ntsiab lus hauv lub thawv.
PP zaj duab xis yog dav siv nyob rau hauv kev lag luam khoom noj khoom haus, xws li hnab, wrapping ntawv, thiab lwm yam saj zawg zog ntim. PP zaj duab xis yog ib zaj duab xis uas pheej yig heev. Qhov kev lag luam ntawm qhov ntsuas no tau tsav qhov kev siv dav dav ntawm cov substrate no nyob rau hauv lub siab -sensitive label market, tshwj xeeb tshaj yog rau lwm cov ntawv sau.
PP zaj duab xis tuaj yeem ua ntej-coated los txhim kho kev luam tawm. Qhov no ua rau nws yog ib qho kev xaiv nrov rau kev sau cov khoom siv nrog cov khoom tsis muaj npe, xws li cov khoom noj thiab dej haus (tshwj xeeb yog iav fwj), kev saib xyuas tus kheej, tsev neeg / tshuaj, thiab tshuaj. Nws yog qhov zoo tagnrho rau semi-extruded thiab rigid ntim. PP zaj duab xis feem ntau pom zoo rau kev siv sab hauv tsev.
PE zaj duab xis: saj zawg zog ntim daim ntawv lo
PE zaj duab xis yog tsuas yog muaj nyob rau hauv ntshiab, pob tshab matte thiab dawb matte, thiab kuj metalized, nrog thicknesses li ntawm 1.5 mils mus rau 4 mils. PE muaj cov tshuaj tiv thaiv zoo heev thiab tuaj yeem tiv taus cov khoom ntim. Nws feem ntau yog tsim los ntawm tshuab moulding lossis casting extrusion txheej txheem. Tshuab moulded cov khoom yog nruj dua li cov khoom cam khwb cia, uas tsis yog -kev taw qhia, hloov tau yooj yim substrates uas zoo tagnrho rau cov ntawv thov uas yuav tsum tau deformation heev los yog extrudability.
High-density PE films are generally highly durable, offering excellent stiffness and medium elongation. Qhov no ua rau nws yooj yim rau dispense, tab sis nws nyiam muaj ntau cov gel thiab blemishes piv rau nruab nrab - ntom version. Cov kev tsis zoo no tuaj yeem ua rau luam ntawv nyuaj. Tam sim no, cov neeg muag khoom muab ntau qhov nruab nrab / siab ceev hybrids kom ua tiav qhov sib npaug zoo tshaj plaws ntawm ob.
Cov yeeb yaj kiab tshwj xeeb: daim ntawv thov raug cai
Cov yeeb yaj kiab tshwj xeeb yog hais txog cov khoom siv ua yeeb yaj kiab uas muaj lub luag haujlwm tshwj xeeb, ntsuas kev ua haujlwm siab thiab cov ntawv thov raug kho, uas txawv ntawm cov yeeb yaj kiab yas. Nws ua tiav kev tswj hwm ntawm ib puag ncig yam xws li lub teeb, cua sov, dej vapor, thiab oxygen los ntawm precision technology thiab cov khoom tsim, thiab yog dav siv hauv electronics, kev kho mob, tshiab zog thiab lwm yam.
Polycarbonate (PC) films nrog zoo heev kho qhov muag, txhua yam, thermal, thiab tshuaj muaj zog, thiab cov kev siv ib txwm muaj xws li graphic overlays ntawm membrane keyboards, nrog rau cov backlit markers qhov twg ib sab ntawm lub logo raug UV teeb thiab lwm sab yog raug kub vim nyob rau hauv illumination. Nyob rau tib lub sijhawm, nws kuj yog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum tau rov ua haujlwm lossis siv tas li. Cov cuab yeej vaj huam sib luag thiab dials feem ntau yog siv cov ntawv tuab dua polycarbonate. Hauv cov xwm txheej no, feem ntau yuav tsum tau luam ntawv nto thiab tom qab ntawd cov duab kos rau ntawm daim ntawv thov nto siv daim kab xev hloov.
Acrylic zaj duab xis muaj cov yam ntxwv ntawm cov pob tshab zoo, huab cua tsis kam, yoog raws thiab tshuaj lom neeg ruaj khov, thiab tuaj yeem siv rau hauv optics, architectural kho kom zoo nkauj, khoom siv hluav taws xob, kev kho mob thiab lwm yam.
Hauv cov ntsiab lus, thaum xaiv cov ntaub ntawv zaj duab xis, nws yog qhov yuav tsum tau ua kom tiav cov khoom ntsuas xws li kev siv daim ntawv lo, ib puag ncig yuav tsum, txheej txheem luam ntawv thiab nqi. Yog tias qhov kub thiab txias thiab kev tiv thaiv ib puag ncig yog xav tau, PET zaj duab xis yog nyiam; Yog xav tau kev shrinkage siab, PET zaj duab xis yog tsim nyog dua; Yog tias tus nqi nkag siab, PVC zaj duab xis lossis PE zaj duab xis tuaj yeem raug txiav txim siab; Yog tias nws yog daim ntawv thov tshwj xeeb, PC zaj duab xis lossis acrylic zaj duab xis yog qhov tsim nyog dua.
