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.

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.

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.

Cov khoom siv aluminium-ingots, coils, profiles, thiab nplooj ntawv-tam sim no ntim cov kev cov nyom uas zoo tib yam strapping tsis 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.

PET pluaj (polyester pluaj) muaj kev pom zoo cia lub neej ntawm 18-36 lub hlis raws li qhov tsim nyog. Kub, av noo, UV raug, thiab kev ruaj ntseg ntim tag nrho cuam tshuam ntev npaum li cas PET pluaj tuav nws txoj haujlwm.

Kev lag luam ntim khoom hnyav xav tau txoj hlua khi uas tuav hauv qhov nro, tiv thaiv kev puas tsuaj, thiab muaj sia nyob sab nraum zoov cia thiab dej hiav txwv. PET pluaj (polyester pluaj) thiab hlua polyester yog ob qho tib si siv rau kev ruaj ntseg, tab sis lawv ua tau txawv heev. Polyester hlua stretches nyob rau hauv load, poob nro raws li cargo settles, thiab abrades sai sai tiv thaiv cov npoo hlau.

PET pluaj (polyester pluaj) muaj nyob rau hauv thicknesses xws li 0.4mm mus rau 1.25mm, nrog rau txhua yam haum rau tej yam yuav tsum tau load thiab cov khoom hom. Thinner straps (0.4-0.55mm) pab lub teeb pallet loads thiab ntim dav, thaum xaiv thicker (0.8-1.25mm) tuav steel coils, paj rwb bales, thiab cov kev xav tau tshaj plaws kev lag luam.

Qhov ntev ntawm cov tub ntxhais yog ib qho ntawm cov kev qhia tshwj xeeb tshaj plaws thaum cov neeg yuav khoom xaiv PET pluaj (polyester pluaj) rau kev ua haujlwm tsis siv neeg strapping. Lub pluaj uas ua tau raws li txhua yam kev xav tau - qhov dav dav, tuab, thiab lub zog tawg - tseem yuav ua rau muaj teeb meem pub mis yog tias nws qhov loj me tsis phim lub taub hau lub taub hau. Core puab txoj kab uas hla, yob dav, thiab yob sab nraud txoj kab uas hla yuav tsum tau sib xws nrog lub tshuab spindle thiab unwinding mechanism. Cov lus qhia no piav qhia txog PET pluaj cov ntsiab lus qhov ntev, lawv cuam tshuam li cas lub taub hau tsis siv neeg lub taub hau, thiab yuav ua li cas txheeb xyuas qhov sib haum ua ntej yuav khoom.

Kev xaiv ntawm PET pluaj (polyester pluaj) thiab steel strapping yog ib qho kev txiav txim siab tshaj plaws hauv kev ntim khoom. PET pluaj muaj txog li 50% tus nqi txuag ib ko taw, tshem tawm kev raug mob los ntawm cov npoo ntse thiab snap-rov qab, thiab muab kev ceev nro zoo dua li cov khoom thauj thaum lub sijhawm thauj mus los. Steel strapping muab siab tshaj plaws rigidity rau hnyav loads tab sis nqa cov nqi zais nrog rau cov kev xav tau ntawm kev ua hauj lwm ntau dua, rusting kab mob txaus ntshai, thiab cov khoom siv hnav. Raws li cov ntaub ntawv hauv kev lag luam, PET pluaj muab plaub npaug ntawm cov kab ntawv ib tuj piv rau cov hlau, hloov pauv tus nqi sib npaug.
