Tam sim no, cov yeeb yaj kiab siab thiab ntau yam kev ua haujlwm tau tsim los rau qib tshiab. Raws li cov yeeb yaj kiab ua haujlwm, vim nws txoj haujlwm tshwj xeeb, nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom ntim khoom, lossis zoo dua raws li cov kev xav tau ntawm cov khoom siv yooj yim, yog li cov nyhuv zoo dua thiab muaj kev sib tw hauv kev ua lag luam. Ntawm no, peb yuav tsom mus rau BOPP thiab PET zaj duab xis
BOPP, los yog Biaxially Oriented Polypropylene, yog ib hom yas zaj duab xis dav siv hauv ntim thiab sau ntawv. Nws tau dhau los ua cov txheej txheem biaxial orientation, txhim kho nws qhov tseeb, lub zog, thiab luam tawm. Paub txog nws txoj kev ua tau zoo, BOPP feem ntau yog siv rau hauv cov ntim khoom yooj yim, cov ntawv lo, cov nplaum nplaum, thiab daim ntaub ntawv lamination. Nws muab cov khoom lag luam pom tau zoo, ua haujlwm ntev, thiab rov ua dua tshiab, ua rau nws muaj kev xaiv nrov rau ntau yam kev xav tau ntim.
PET, los yog Polyethylene Terephthalate, yog siv dav siv thermoplastic polymer paub txog nws txoj kev ua tau zoo thiab pom tseeb. Feem ntau siv los tsim lub raj mis yas rau dej haus, ntim khoom noj, thiab ntim khoom, PET yog pob tshab thiab muaj cov khoom thaiv zoo heev tiv thaiv oxygen thiab noo noo. Nws yog lub teeb yuag, ruaj khov, thiab rov ua dua tshiab, ua rau nws yog qhov kev xaiv nrov rau ntau daim ntawv thov ntim. Tsis tas li ntawd, PET yog siv hauv fibers rau khaub ncaws, nrog rau kev tsim cov yeeb yaj kiab thiab cov ntawv txheeb rau ntau lub hom phiaj.
Qhov txawv
PET stands rau polyethylene terephthalate, thaum BOPP stands rau biaxially oriented polypropylene. PET thiab BOPP zaj duab xis yog cov yas yas uas feem ntau siv rau ntim. Ob qho tib si yog cov kev xaiv nrov rau ntim khoom noj thiab lwm yam kev siv, xws li cov ntawv cim khoom thiab cov ntaub thaiv npog.
Hais txog qhov sib txawv ntawm PET thiab BOPP zaj duab xis, qhov sib txawv tshaj plaws yog tus nqi. PET zaj duab xis nyiam kim dua li BOPP zaj duab xis vim nws lub zog zoo dua thiab cov khoom thaiv. Thaum BOPP zaj duab xis yog tus nqi ntau dua, nws tsis muab tib yam kev tiv thaiv lossis thaiv cov khoom zoo li PET zaj duab xis.
Ntxiv rau cov nqi, muaj qhov sib txawv ntawm qhov kub thiab txias ntawm ob hom yeeb yaj kiab. PET zaj duab xis muaj cov ntsiab lus melting ntau dua li BOPP zaj duab xis, yog li nws tuaj yeem tiv taus qhov kub siab dua yam tsis muaj warping lossis shrinking. BOPP zaj duab xis yog ntau resistant rau ya raws, yog li nws muaj peev xwm tiv thaiv cov khoom uas rhiab heev rau ya raws.
Hais txog cov khoom siv kho qhov muag ntawm PET thiab BOPP zaj duab xis, PET zaj duab xis muaj qhov pom tseeb zoo dua thiab ci, thaum BOPP zaj duab xis muaj matte tiav. PET zaj duab xis yog qhov kev xaiv zoo dua yog tias koj tab tom nrhiav ib zaj duab xis uas muaj cov khoom siv kho qhov muag zoo.
PET thiab BOPP zaj duab xis yog tsim los ntawm cov yas resins tab sis muaj cov khoom sib txawv. PET muaj xws li polyethylene terephthalate, sib txuas ob monomers, ethylene glycol, thiab terephthalic acid. Qhov kev sib xyaw ua ke no tsim cov khoom siv muaj zog thiab lub teeb yuag heev tiv taus cua sov, tshuaj, thiab cov kuab tshuaj. Ntawm qhov tod tes, BOPP zaj duab xis yog tsim los ntawm biaxially-oriented polypropylene, ua ke ntawm polypropylene thiab lwm yam khoom siv hluavtaws. Cov khoom no kuj muaj zog thiab hnav, tab sis tsis tshua muaj resistant rau tshav kub thiab tshuaj.
Ob qho khoom siv muaj ntau qhov sib xws ntawm cov khoom ntawm lub cev. Ob leeg yog pob tshab heev thiab muaj qhov pom tseeb zoo, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau kom pom tseeb ntawm cov ntsiab lus. Tsis tas li ntawd, ob qho tib si cov ntaub ntawv muaj zog thiab hloov tau, ua rau lawv haum rau ntau yam kev siv.
Txawm li cas los xij, muaj qee qhov sib txawv tseem ceeb. PET yog nruj dua li BOPP zaj duab xis thiab tsis tshua muaj kev cuam tshuam los yog tawg. PET muaj cov ntsiab lus melting ntau dua thiab tiv taus UV hluav taws xob ntau dua. Ntawm qhov tod tes, BOPP zaj duab xis yog ntau malleable thiab tuaj yeem ncab thiab zoo li tus kom haum rau ntau yam kev siv.
Cov ntsiab lus
Hauv kev xaus, zaj duab xis tsiaj thiab Bopp zaj duab xis muaj lawv qhov sib txawv. PET zaj duab xis yog polyethylene terephthalate zaj duab xis, ua rau nws yog ib qho thermoplastic uas tuaj yeem ua kom sov thiab zoo li tus yam tsis tau poob nws qhov kev ncaj ncees. Nws muaj kev ruaj ntseg zoo heev, kho qhov muag, thiab tshuaj tiv thaiv, ua rau nws xaiv zoo rau ntau daim ntawv thov. Bopp zaj duab xis, ntawm qhov tod tes, yog biaxially-oriented polypropylene zaj duab xis. Nws yog ib lub teeb yuag tab sis muaj zog cov khoom nrog zoo heev optical, mechanical, thiab thermal zog. Nws yog qhov muaj txiaj ntsig zoo hauv cov ntawv thov uas xav tau kom meej meej thiab lub zog zoo dua.
Thaum xaiv ntawm ob zaj duab xis no, nws yog ib qho tseem ceeb uas yuav tau xav txog daim ntawv thov. PET zaj duab xis yog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum muaj kev ruaj ntseg zoo thiab tshuaj lom neeg. Bopp zaj duab xis yog tsim nyog rau daim ntawv thov uas xav tau siab clarity thiab superior zog.
Peb cia siab tias qhov blog no tau pab koj nkag siab zoo dua qhov sib txawv ntawm cov tsiaj thiab Bopp zaj duab xis thiab xaiv qhov uas haum rau koj daim ntawv thov.
