PET pluaj (polyester pluaj) muab nws lub zog los ntawm qhov hnyav molecular ntawm nws cov khoom siv raw, uas yog ntsuas los ntawm cov viscosity intrinsic (IV). Qhov feem ntau IV rau qhov zoo PET pluaj yog 0.60 txog 0.95 dl / g.

Xaiv txoj cai PP pluaj (polypropylene pluaj) qhov dav yog qhov tseem ceeb rau kev ruaj ntseg thauj khoom, khoom siv sib xws, thiab kev siv nyiaj. PP pluaj muaj nyob rau hauv cov qauv dav ntawm 5mm txog 19mm. Cov hlua me me (5-9mm) haum lub teeb thawv thiab e-lag luam, thaum txoj hlua dav (12-19mm) tuav cov pallets hnyav thiab cov khoom lag luam.

PP strapping (polypropylene strapping) feem ntau muaj kev tawg rog txij li 45kg txog 230kg, nyob ntawm qhov dav, tuab, thiab qib kev tsim khoom. Qhov ntau yam no haum rau cov ntawv thov los ntawm lub teeb lub thawv ntim rau lub luag haujlwm hnyav pallet bundling.

PET pluaj (polyester pluaj) tau hloov steel strapping nyob rau hauv ntau daim ntawv thov ntim, muab piv tensile lub zog ntawm ib-rau ntawm qhov hnyav, tsis muaj xeb, tsis muaj qhov ntse ntse, thiab 30-50% tus nqi qis dua. Tab sis nws puas tuaj yeem hloov steel tag? Cov lus teb yog: nyob rau hauv ntau daim ntawv thov, yog, tab sis tsis yog tag nrho.

PP pluaj (polypropylene pluaj) muaj kev tawg rog xws li 45kg txog 230kg nyob ntawm qhov dav thiab tuab. Qhov ntau yam no haum rau cov ntawv thov los ntawm lub teeb thawv ntim rau hnyav pallet bundling.

PET pluaj (polyester pluaj) ua tiav lub zog tawg ntawm 160kg txog 1,360kg nyob ntawm qhov dav thiab tuab. Qhov ntau yam no haum rau cov ntawv thov los ntawm lub teeb pallet loads rau hnyav steel coil bundling thiab paj rwb bale ntim. Kev quab yuam yog txiav txim siab los ntawm txoj hlua khi ntawm qhov chaw hla ntu thiab molecular orientation thaum tsim khoom.

PP strapping (polypropylene strapping) yog muaj nyob rau hauv thicknesses los ntawm 0.35mm mus rau 0.80mm, nrog rau txhua yam haum rau tej yam load, hom khoom, thiab printing xav tau kev pab. Thinner straps (0.35–0.45mm) pab lub teeb cartons thiab e-commerce ntim, thaum cov kev xaiv thicker (0.55–0.80mm) tuav tshuaj cartons, pallet loads, thiab industrial bundling.

Cov khoom siv aluminium-ingots, coils, profiles, thiab nplooj ntawv-tam sim no ntim cov nyom uas zoo tib yam strapping tsis tuaj yeem daws tau. Hnyav hnyav, ntse npoo, nto rhiab heev, sab nraum zoov cia, thiab dej hiav txwv hla kev xav tau strapping nrog lub zog tensile siab, tsis tshua muaj elongation, tsis muaj xeb, thiab huab cua tsis kam.

PET pluaj (polyester pluaj) tau dhau los ua lwm txoj hauv kev niaj hnub rau cov hlua khi hlau thoob plaws kev lag luam xws li kev ua hlau mus rau paj rwb ginning. Nws muaj steel zoo li tensile lub zog ntawm ib-rau ntawm qhov hnyav, tshem tawm kev raug mob ntawm cov npoo ntse thiab snap-rov qab, thiab tiv thaiv xeb thiab xeb.

PP strapping (polypropylene strapping) muab nws lub zog los ntawm peb theem kev tsim khoom: extrusion, stretching, thiab molecular alignment. Thaum lub sij hawm extrusion, polypropylene cob yog melted thiab tsim rau hauv ib tug nruam ca band.
