Tsiaj, lossis polyethylene terephthalate, yog qhov siv thermoplashic polymer paub txog nws cov versatility thiab meej. Feem ntau yog siv nyob rau hauv kev tsim cov roj tov yas rau dej haus, khoom noj khoom haus, tsiaj yog pob tshab thiab muaj cov teeb meem zoo heev rau oxygen thiab noo noo. Nws yog lub teeb ci ntsa iab, ruaj, thiab rov ua dua, ua rau nws xaiv cov kev xaiv nrov rau ntau yam kev siv. Ib qho ntxiv, cov tsiaj siv hauv fibers rau cov khaub ncaws, nrog rau hauv kev tsim cov yeeb yaj kiab thiab cov ntawv txheeb rau ntau lub hom phiaj.
Qhov txawv
Tus tsiaj sawv rau polyethylene terephthalate, thaum bopp sawv rau biaxial ended polypropylene. Cov tsiaj thiab cov yeeb yaj kiab bopp yog cov yeeb yaj kiab yas yas feem ntau siv rau kev ntim khoom. Ob qho tib si yog xaiv nrov rau cov khoom noj ntim khoom thiab lwm yam khoom siv, cov ntaub qhwv cov khoom tiv thaiv.
Hais txog qhov sib txawv ntawm cov tsiaj thiab cov yeeb yaj kiab bopp, qhov sib txawv tshaj plaws yog tus nqi. Cov tsiaj zaj duab xis yeej yog kim dua li BOPP zaj yeeb yaj kiab vim nws lub zog zoo dua thiab cov khoom siv hluav taws xob. Thaum lub sij hawm BOP zaj yeeb yaj kiab muaj txiaj ntsig zoo dua, nws tsis muab cov khoom tiv thaiv tib yam lossis cov teeb meem tsiaj raws li tsiaj zaj duab xis.
Hais txog cov khoom siv kho tshiab ntawm cov tsiaj thiab cov yeeb yaj kiab tsiaj, cov yeeb yaj kiab tsiaj muaj cov yeeb yaj kiab zoo dua thiab cov yeeb yaj kiab ua tiav muaj lub ntsej muag matte. Tsiaj zaj duab xis yog qhov kev xaiv zoo dua yog tias koj tab tom nrhiav ib zaj yeeb yaj kiab uas muaj cov khoom kho tshiab zoo heev.
Cov tsiaj thiab cov yeeb yaj kiab bopp yog tsim los ntawm cov roj yas tab sis muaj cov khoom sib txawv. Tus tsiaj muaj polyethylene terepthalate, sib txuas ob monomers, ethylene glycol, thiab terephthalic acid. Qhov kev sib xyaw no tsim muaj zog thiab lub teeb yuag heev tiv thaiv kom sov, tshuaj lom neeg, thiab cov kuab tshuaj. Ntawm qhov tod tes, BOP zaj yeeb yaj kiab yog tsim los ntawm biaxially-taw polypropylene, kev sib xyaw ntawm polypropylene thiab lwm yam hluavtaws cheebtsam. Cov khoom siv no kuj muaj zog thiab hnyav tab sis tsis tshua muaj kev tiv thaiv kom sov thiab tshuaj lom neeg.
Ob yam khoom muaj ntau yam sib xws ntawm cov khoom siv lub cev. Ob qho tib si yog pob tshab thiab muaj qhov pom tseeb zoo heev, ua rau lawv zoo tshaj rau cov ntawv thov uas xav tau pom meej txog cov ntsiab lus. Ib qho ntxiv, ob yam khoom siv tau ruaj khov thiab hloov tau yooj yim, ua rau lawv haum rau ntau yam kev siv.
Txawm li cas los xij, muaj qee qhov sib txawv. Tus tsiaj yog ntau dua rigid dua li bopp zaj duab xis thiab tsis tshua muaj kev ntuag lossis puncturing. Tus tsiaj muaj ntau dua melting taw tes thiab yog tiv taus ntau dua UV hluav taws xob. Ntawm qhov tod tes, BOP zaj yeeb yaj kiab yog ntau malalle thiab tuaj yeem ua xyab thiab puab kom haum ntau yam kev siv.
lub ntsiab
Hauv kev xaus, cov yeeb yaj kiab tsiaj thiab BOPP zaj yeeb yaj kiab muaj lawv qhov sib txawv. Tsiaj zaj duab xis yog polyethylene terephthalate zaj duab xis, ua rau nws lub thermoplastic uas tuaj yeem ua kom sov thiab zoo li yam tsis poob nws cov qauv kev ncaj ncees. Nws muaj cov khoom siv kho tau zoo heev, kho qhov muag tsis pom zoo, thiab tshuaj lom neeg tiv thaiv, ua nws txoj kev xaiv zoo rau ntau daim ntawv thov. Cov yeeb yaj kiab BOPP, ntawm qhov tod tes, yog biaxous-endeed polypropylene zaj duab xis. Nws yog ib lub teeb yuag txawm tsis muaj cov khoom siv muaj zog nrog cov khoom siv kho tshiab, mechanical, thiab cov khoom thermal. Nws muaj txiaj ntsig hauv cov ntawv thov uas muaj zog dua thiab zoo dua lub zog.
Thaum xaiv nruab nrab ntawm ob zaj yeeb yaj kiab no, nws yog qhov tseem ceeb los xav txog daim ntawv thov. Tsiaj zaj duab xis yog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum muaj kev ruaj khov ntawm seem thiab tshuaj lom neeg tiv thaiv. BOPP zaj yeeb yaj kiab yog qhov tsim nyog rau cov ntawv thov uas yuav tsum muaj qhov tseeb thiab zoo dua lub zog.
Peb cia siab tias cov blog no tau pab koj nkag siab zoo dua qhov sib txawv ntawm cov tsiaj thiab xaiv ib qho uas haum rau koj daim ntawv thov.
