Zaj duab xis polypropylene biaxially oriented (zaj duab xis BOPP luv luv) yog cov khoom siv ntim khoom zoo heev uas pob tshab thiab yoog tau. Zaj duab xis polypropylene biaxially oriented muaj qhov zoo ntawm lub cev thiab lub zog kho tshuab siab, lub cev nyhav tsis hnyav, tsis muaj tshuaj lom, tiv taus dej noo, siv tau dav thiab ua haujlwm ruaj khov. Raws li kev siv sib txawv, zaj duab xis polypropylene biaxially oriented muaj peev xwm muab faib ua zaj duab xis kaw cua sov, zaj duab xis lo, zaj duab xis matte, zaj duab xis ib txwm thiab zaj duab xis capacitor.
Polypropylene yog ib yam khoom siv tseem ceeb rau cov yeeb yaj kiab polypropylene uas tig tau ob sab. Polypropylene yog cov thermoplastic synthetic resin uas muaj kev ua tau zoo heev. Nws muaj qhov zoo ntawm kev ruaj khov zoo, tiv taus kub thiab rwb thaiv hluav taws xob zoo, thiab muaj kev thov ntau hauv kev ntim khoom. Xyoo 2021, kuv lub teb chaws cov polypropylene (PP) tsim tawm yuav ncav cuag 29.143 lab tons, nce 10.2% txhua xyoo. Vim muaj cov khoom siv raw txaus, kev lag luam polypropylene uas tig tau ob sab ntawm kuv lub teb chaws tau tsim kho sai, thiab nws cov zis tau txuas ntxiv nce ntxiv. Raws li cov ntaub ntawv los ntawm National Bureau of Statistics, kuv lub teb chaws cov yeeb yaj kiab polypropylene uas tig tau ob sab yuav ncav cuag 4.076 lab tons hauv xyoo 2021, nce 8.7%.
Cov txheej txheem tsim cov yeeb yaj kiab polypropylene biaxially oriented muaj xws li txoj kev ua yeeb yaj kiab tubular thiab txoj kev ua yeeb yaj kiab tiaj tiaj. Vim tias qhov zoo tsis sib xws thiab kev ua haujlwm tsawg ntawm cov khoom tsim los ntawm txoj kev ua yeeb yaj kiab tubular, lawv tau raug tshem tawm maj mam los ntawm cov tuam txhab loj. Txoj kev ua yeeb yaj kiab tiaj tiaj tuaj yeem muab faib ua txoj kev ncab biaxial tib lub sijhawm thiab txoj kev ncab biaxial kauj ruam. Cov txheej txheem ncab biaxial kauj ruam yog raws li nram no: cov khoom siv raw → extrusion → casting → longitudinal ncab → ntug trimming → kho corona → winding → zaj duab xis loj yob → laus → txiav → cov khoom tiav. Tam sim no, txoj kev ncab biaxial maj mam tau txais los ntawm feem ntau cov tuam txhab vim nws qhov zoo ntawm kev siv tshuab laus, kev ua haujlwm siab, thiab kev tsim khoom loj.
Cov yeeb yaj kiab polypropylene uas muaj ob sab (biaxially oriented polypropylene film) siv dav hauv cov khoom ntim xws li khaub ncaws, khoom noj, tshuaj, luam ntawv, haus luam yeeb thiab cawv. Tam sim no, cov yeeb yaj kiab polypropylene uas muaj ob sab tau hloov cov yeeb yaj kiab ntim khoom ib txwm xws li polyethylene (PE), polypropylene (PP), thiab polyvinyl chloride (PVC). Kuv lub teb chaws yog lub teb chaws ntim khoom thib ob loj tshaj plaws hauv ntiaj teb, thiab qhov kev thov rau kev ntim khoom txuas ntxiv mus. Raws li cov ntaub ntawv los ntawm Tuam Tshoj Packaging Federation, cov nyiaj tau los ntawm cov lag luam saum toj no qhov loj me hauv kuv lub teb chaws kev lag luam ntim khoom yuav ncav cuag 1,204.18 billion yuan hauv xyoo 2021, nce ntxiv 16.4%. Nrog rau kev txhim kho sai ntawm kuv lub teb chaws kev lag luam ntim khoom, cov yeeb yaj kiab polypropylene uas muaj ob sab yuav muaj kev cia siab dav dav ua cov khoom ntim khoom tseem ceeb.
Cov kws tshuaj ntsuam kev lag luam los ntawm Xinsijie tau hais tias tau txais txiaj ntsig los ntawm kev muab cov khoom siv raw txaus thiab kev paub tab ntawm cov thev naus laus zis tsim khoom, lub peev xwm tsim kho ntawm kuv lub teb chaws txoj kev lag luam polypropylene biaxially oriented yog qhov loj heev. Kev loj hlob sai ntawm kev lag luam ntim khoom yuav tsav tsheb ntxiv kev nthuav dav ntawm kuv lub teb chaws txoj kev lag luam polypropylene biaxially oriented. Nrog rau kev nkag siab tob txog lub tswv yim ntawm kev siv ntsuab, cov neeg siv khoom yuav txhim kho cov kev xav tau zoo ntawm cov ntaub ntawv ntim khoom, thiab cov yeeb yaj kiab polypropylene biaxially oriented uas txuag hluav taws xob thiab zoo rau ib puag ncig yuav dhau los ua lub hauv paus ntawm kev ua lag luam.
