Polypropylene
Polypropylene (PP) yog cov ntsiab lus siab melting-point thermoplastic polymer nrog cov khoom zoo heev, ua rau nws yog ib qho zoo tshaj plaws thermoplastic polymers niaj hnub no.Piv nrog rau lwm cov ntaub ntawv thermoplastic, nws muaj qhov zoo xws li tus nqi qis, lub teeb yuag, cov khoom siv zoo tshaj plaws nrog rau kev tawm dag zog, lub zog tensile, thiab lub zog saum npoo, tshwj xeeb kev ntxhov siab-tawg tsis kam, thiab kev puas tsuaj, nrog rau kev ruaj ntseg zoo, yooj yim. ntawm molding, thiab ntau yam kev siv.Nws tau siv dav hauv kev lag luam xws li tshuaj lom neeg, hluav taws xob, tsheb, kev tsim kho, thiab ntim khoom.
Kev lag luam ntim tau hloov pauv cov ntawv loj nrog cov yeeb yaj kiab yas rau cov ntim mos, los ntawm cov khoom noj mus rau lwm yam khoom.Cov yeeb yaj kiab yas siv rau kev ntim khoom muag yuav tsum ua kom tau raws li qhov yuav tsum tau muaj rau kev tiv thaiv, kev ua haujlwm, yooj yim, thiab cov khoom ntim khoom lag luam, nrog rau lub zog tsim nyog, cov khoom thaiv kev ruaj ntseg, kev ruaj ntseg, pob tshab, thiab kev yooj yim.
CPP Zaj duab xis: CPP zaj duab xis los ntawm cov hom phiaj dav dav, metallized, thiab boilable hom.Hom hom phiaj yog feem ntau siv thiab tuaj yeem hloov kho nyob rau hauv qee yam.Hom metallized yog cov khoom siv high-end tsim los ntawm cov txheej txheem tshwj xeeb uas siv cov ntaub ntawv tshwj xeeb polypropylene kom ua tau zoo tshaj qhov kub-sealing zog.Hom boilable yog tsim los rau kev kub siab ua hauj lwm thiab feem ntau yog tsim los ntawm random copolymer nrog ib tug siab dua pib thaum tshav kub kub-sealing kub.
CPP zaj duab xis yog ib yam uas tsis yog-stretched, uas tsis yog-oriented ca extruded zaj duab xis ua los ntawm cov cam khwb cia zaj duab xis txoj kev los ntawm unstretched polypropylene.Nws nta lub teeb yuag, siab transparency, zoo flatness, zoo rigidity, siab mechanical adaptability, zoo heev tshav kub-sealing, noo noo tsis kam, thiab tshav kub tsis kam, zoo plam zog, siab zaj duab xis ntau lawm ceev, uniform thickness, zoo noo noo kuj, roj kuj, tshav kub. tsis kam, txias tsis kam, yooj yim ntawm tshav kub sealing, thiab superior tiv thaiv thaiv.Nws cov khoom kho qhov muag yog qhov zoo heev thiab haum rau kev ntim khoom tsis siv neeg.
Txij li thaum nws tau nthuav tawm hauv Suav teb xyoo 1980, kev nqis peev thiab ntxiv tus nqi ntawm CPP zaj duab xis tau ua qhov tseem ceeb.CPP zaj duab xis yog dav siv hauv ntim khoom noj, tshuaj, ntawv sau, tshuaj pleev ib ce, thiab textiles, nrog rau kev siv ntau tshaj plaws hauv kev ntim khoom noj.Nws yog siv los ntim cov khoom noj uas tsis muaj cua sov, cov khoom noj, cov kua zaub, nrog rau cov khoom siv sau, cov duab, cov khoom sau, ntau yam ntawv, thiab daim kab xev.
BOPP Zaj duab xis: BOPP zaj duab xis tuaj yeem raug cais los ntawm kev ua haujlwm rau hauv cov yeeb yaj kiab antistatic, tiv thaiv huab cua, ntxeem tau hloov kho BOPP zaj duab xis, thiab yooj yim luam tawm.
BOPP zaj duab xis
BOPP zaj duab xis yog ib qho kev ua tau zoo, cov khoom ntim pob tshab uas tau tsim nyob rau xyoo 1960s.Nws muaj kev nruj nruj, tsim kua muag lub zog, cuam tshuam tsis kam, zoo noo noo barrier, siab gloss, zoo transparency, zoo gas barrier zog, lub teeb yuag, tsis muaj tshuaj lom, tsis muaj ntxhiab tsw, zoo dimension stability, dav siv, zoo printability, thiab zoo hluav taws xob rwb thaiv tsev zog. .Nws yog dav suav hais tias yog "tus huab tais ntim khoom" hauv kev lag luam ntim khoom.
Antistatic BOPP zaj duab xis yog siv rau ntim cov khoom me me xws li cov ntses hlais, yooj yim-rau-luam BOPP zaj duab xis yog siv rau ntim cov khoom noj, thiab yooj yim-rau-txiav BOPP zaj duab xis yog siv rau ntim cov kua zaub thiab tshuaj.BOPP shrink zaj duab xis, tsim los siv cov txheej txheem biaxially oriented film manufacturing, feem ntau yog siv rau ntim luam yeeb.
IPP Zaj duab xis: IPP zaj duab xis muaj cov khoom siv kho qhov muag qis dua li CPP thiab BOPP, tab sis nws muaj cov txheej txheem yooj yim, tus nqi qis, thiab tuaj yeem muab ntim tau yooj yim rau saum thiab hauv qab rau ntim.Cov yeeb yaj kiab tuab feem ntau yog li ntawm 0.03 txog 0.05mm.Siv cov copolymer resins, nws tuaj yeem tsim cov yeeb yaj kiab nrog lub zog zoo ntawm qhov kub thiab txias.Hloov kho IPP cov yeeb yaj kiab muaj qhov kub tsis tshua muaj siab ua haujlwm, siab plam zog, siab pob tshab, siab cuam tshuam lub zog, zoo yoog raws, thiab cov khoom tiv thaiv zoo li qub.Cov yeeb yaj kiab tuaj yeem suav nrog ib txheej polypropylene zaj duab xis, uas tuaj yeem ua homopolymer lossis copolymer, lossis ntau txheej co-extruded cua tshuab siv homopolymer thiab copolymer cov ntaub ntawv.IPP feem ntau yog siv rau ntim khoom noj txom ncauj, qhob cij, textiles, folders, cov tes tsho sau, seaweed, thiab khau kis las.
Nws cov txheej txheem ntawm cam khwb cia polypropylene zaj duab xis yuav tsum melting thiab plasticizing polypropylene resin los ntawm ib tug extruder, ces extruding nws los ntawm ib tug nqaim slit tuag, ua raws li longitudinal stretching thiab txias ntawm cov khoom molten ntawm ib tug casting roller, thiab thaum kawg undergoing pre-trimming, thickness ntsuas. , slitting, nto kho corona, thiab winding tom qab trimming.Cov yeeb yaj kiab uas tau tshwm sim, hu ua CPP zaj duab xis, tsis muaj tshuaj lom, lub teeb yuag, lub zog siab, pob tshab, glossy, kub-sealable, ya raws-tiv taus, nruj, thiab tuab tuab.Nws muaj ntau yam kev siv, suav nrog ua cov yeeb yaj kiab sib xyaw, cov khoom noj boilable thiab cov khoom ntim kub kub, thiab ntau yam khoom ntim khoom noj, tshuaj, khaub ncaws, textiles, thiab ntaub pua chaw pw.
Kev kho deg ntawm polypropylene zaj duab xis
Kev Kho Corona: Kev kho deg yog qhov tseem ceeb rau cov polymers txhawm rau txhim kho lawv cov ntaub ntub dej thiab adhesion hauv kev lag luam luam ntawv thiab ntim khoom.Cov txuj ci xws li graft polymerization, corona tawm, thiab laser irradiation yog siv rau kev kho deg.Kev kho mob Corona yog ib qho cuab yeej zoo ib puag ncig uas ua rau kom cov concentration ntawm reactive oxygen radicals ntawm lub polymer nto.Nws yog tsim rau cov ntaub ntawv xws li polyethylene, polypropylene, PVC, polycarbonates, fluoropolymers, thiab lwm yam copolymer.Kev kho mob Corona muaj lub sijhawm kho luv luv, nrawm nrawm, ua haujlwm yooj yim, thiab tswj tau yooj yim.Nws tsuas yog cuam tshuam rau qhov tob tob ntawm cov yas, feem ntau nyob rau theem nanometer, thiab tsis cuam tshuam rau cov khoom siv ntawm cov khoom.Nws yog dav siv rau kev hloov kho saum npoo ntawm polyethylene thiab polypropylene zaj duab xis thiab fibers, vim nws yog ib qho yooj yim mus thov thiab muaj kev kho mob zoo yam tsis muaj kuab paug ib puag ncig.
Cov yam ntxwv saum npoo ntawm Polypropylene Zaj duab xis: Polypropylene zaj duab xis yog cov khoom siv tsis muaj polar crystalline, uas ua rau cov ink compatibility tsis zoo thiab txo qhov ntub dej vim kev tsiv teb tsaws thiab tsim cov khoom hnyav molecular xws li plasticizers, pib, residual monomers, thiab degradation khoom, uas tsim ib qho amorphous. txheej uas txo qhov kev ua tau zoo ntawm qhov ntub dej, yuav tsum tau kho ua ntej luam ntawv kom ua tiav cov ntawv luam tawm zoo.Tsis tas li ntawd, qhov tsis zoo ntawm polypropylene yas zaj duab xis nthuav tawm cov kev sib tw rau kev ua haujlwm theem nrab xws li kev sib txuas, txheej, lamination, aluminium plating, thiab kub stamping, ua rau kev ua tau zoo.
Lub hauv paus ntsiab lus thiab Microscopic Phenomena ntawm Kev Kho Kab Mob Corona: Raws li kev cuam tshuam ntawm cov hluav taws xob hluav taws xob siab, cov yeeb yaj kiab polypropylene raug cuam tshuam los ntawm cov hluav taws xob muaj zog, uas ua rau muaj qhov roughening.Qhov no yog vim cov txheej txheem oxidation thiab molecular saw breakage cov khoom ntawm polypropylene zaj duab xis nto, ua rau siab dua nto nro dua li thawj zaj duab xis.Kev kho mob Corona ua rau muaj tus lej tseem ceeb ntawm ozone plasma hais tias cuam tshuam ncaj qha lossis tsis ncaj qha nrog cov yas zaj duab xis nto, ua rau muaj kev sib cais ntawm cov ntawv cog lus siab molecular rau ntawm qhov chaw thiab tsim cov radicals sib txawv thiab cov chaw tsis txaus ntseeg.Cov av ntiav cov radicals thiab cov chaw tsis txaus siab no ces hnov mob nrog dej hauv qhov chaw los tsim cov pawg polar functional, ua kom cov yeeb yaj kiab polypropylene.
Hauv cov ntsiab lus, ntau hom polypropylene zaj duab xis thiab ntau yam kev siv, nrog rau ntau yam txheej txheem kho saum npoo, xyuas kom meej tias nws ua tau raws li qhov yuav tsum tau ua hauv kev ntim khoom thiab lwm yam.
