Zaj duab xis ncab, tseem hu ua zaj duab xis ncab thiab zaj duab xis cua sov ntsws, thawj zaug tsim tawm hauv Suav teb siv PVC ua cov khoom siv tseem ceeb thiab DOA ua cov khoom siv yas thiab cov nyhuv nplaum ntawm PVC zaj duab xis ncab. Vim muaj teeb meem ib puag ncig, tus nqi siab (piv rau PE, thaj chaw ntim khoom tsawg dua ib chav) thiab kev ncab tsis zoo, PE zaj duab xis ncab tau raug tshem tawm thaum pib tsim khoom hauv tebchaws xyoo 1994-1995. Cov khoom siv tseem ceeb yog LLDPE, suav nrog C4, C6, C8 thiab metallocene PE (MPE).
Cov yam ntxwv
Nws yog tsim los ntawm kev siv cov khoom siv LLDPE uas xa tuaj thiab cov khoom siv tackifier tshwj xeeb uas muaj cov mis sib piv, thiab tuaj yeem tsim cov yeeb yaj kiab winding ntau yam rau tes, tshuab hom tiv taus, tshuab hom ua ntej ncab, tiv thaiv UV, tiv thaiv zoo li qub thiab tiv thaiv xeb. Nws muaj cov txiaj ntsig zoo li nram no:
1. Siv cov khoom siv ob txheej co-extrusion, cov zaj duab xis winding nias tuaj yeem ua kom cov yam ntxwv ntawm txhua tus polymer, nws cov pob tshab, lub zog tensile, thiab kev tiv thaiv perforation, mus txog qhov zoo tshaj plaws ntawm qhov chaw yaj.
2. Nws muaj cov khoom tensile zoo, pob tshab zoo, thiab tuab sib xws.
3. Nws muaj qhov ntev elongation, zoo resilience, zoo kab rov tav tear tsis kam, thiab zoo heev tus kheej-nplaum lap.
4. Nws yog cov khoom siv rov ua dua tshiab uas zoo rau ib puag ncig, tsis muaj saj, tsis muaj tshuaj lom, tuaj yeem ntim khoom noj ncaj qha.
5. tuaj yeem tsim cov khoom nplaum ib sab, txo cov suab nrov thaum lub sijhawm winding thiab ncab, txo cov hmoov av thiab xuab zeb hauv cov txheej txheem ntawm kev thauj mus los thiab khaws cia.
Daim Ntawv Thov
1. Ntim khoom kaw
Hom kev ntim khoom no zoo ib yam li cov yas ntim khoom uas ntsws, qhov twg cov yas qhwv ib ncig ntawm lub pallet kom qhwv tag nrho, thiab tom qab ntawd ob lub tshuab cua sov kaw cov yas ntawm ob qho kawg ua ke. Qhov no yog hom yas qhwv ib puag ncig uas siv thaum ub thiab tau ua rau muaj kev txhim kho ntau hom kev ntim khoom.
2. Ntim tag nrho dav
Hom ntim khoom no xav kom zaj duab xis dav txaus los npog lub pallet, uas muaj cov duab ib txwm muaj, yog li nws tsim nyog siv nrog zaj duab xis tuab ntawm 17 txog 35μm.
3. Kev ntim khoom siv tes
Hom ntim khoom no yog hom ntim zaj duab xis yooj yim tshaj plaws, zaj duab xis tau teeb tsa rau ntawm txee lossis tuav tes, los ntawm kev tig lub pallet lossis zaj duab xis ncig lub pallet. Nws feem ntau yog siv rau hauv kev rov ntim cov pallets qhwv tom qab tawg, thiab cov ntim pallet ib txwm muaj. Hom ntim khoom no qeeb thiab qhov tuab ntawm zaj duab xis tsim nyog yog 15 txog 20 μm.
