Qhov txawv: TPU Pellet Thiab LGF TPU Composite
TPU (thermoplastic polyurethane) thiab LGF TPU (ntev iav fiber reinforced thermoplastic polyurethane) yog ob yam khoom sib txawv. Qhov sib txawv tseem ceeb ntawm lawv nyob rau hauv seb ntev iav fibers ntxiv. Hauv cov ntsiab lus yooj yim, LGF TPU yog TPU nrog ntev iav fibers ntxiv, uas txhim kho nws cov kev ua tau zoo.
TPU (Thermoplastic Polyurethane)
TPU pellet yog cov khoom siv polymer uas muaj npe nrov rau nws cov elasticity zoo heev, hnav tsis kam, roj tsis kam, thiab qis -kub tsis kam. Nws cov qauv molecular muab rau nws cov roj hmab-zoo li yooj yooj yim thaum tseem muaj cov yam ntxwv ntawm cov yas. Txawm li cas los xij, nws kuj muaj qhov tsis zoo. Lub drawback ntawm TPU pellet yog nws tsis txaus rigidity, uas tej zaum yuav tsis tau raws li qhov yuav tsum tau muaj nyob rau hauv tej yam structural Cheebtsam uas xav tau siab zog thiab rigidity.
LGF TPU (ntev iav Fiber Reinforced Thermoplastic Polyurethane)
LGF TPU yog cov khoom sib xyaw tsim los ntawm kev ntxiv cov iav fiber ntau (nrog qhov ntev feem ntau ntau dua 5 hli) rau cov khoom siv hauv TPU los ntawm cov txheej txheem tshwj xeeb. Cov fibers ntev no tsim peb - cov qauv sib txuas sib txuas hauv cov khoom siv, ua kom nws qhov kev ua tau zoo.
Piv nrog TPU polymer, lub ntsiab zoo ntawm LGF TPU composite nyob rau hauv:
Siab zog thiab rigidity:Qhov sib ntxiv ntawm cov iav fibers ntev tau txhim kho lub zog tensile, khoov lub zog thiab modulus ntawm cov khoom, ua kom nws hloov tau qee cov hlau lossis cov khoom siv yas yas.
Zoo dua dimensional stability:Cov iav fibers ntev txo cov thermal expansion thiab contraction ntawm cov khoom, ua rau cov khoom tsim ruaj khov nyob rau hauv cov nqe lus ntawm qhov loj me ntawm qhov sib txawv kub thiab tsis tshua muaj deformation.
Kev kub siab dua:Cov khoom siv txhawb zog tuaj yeem tiv taus kev ua haujlwm siab dua.
Zoo dua los tiv thaiv- xeb khoom:Nyob rau hauv lub sij hawm ntev - kev ntxhov siab, cov khoom siv deformation tsawg dua.
Daim ntawv thov ntau yam ntawm TPU thiab LGF TPU Khoom
Cov ntawv thov ntawm TPU pellet yog qhov dav heev, piv txwv li:
Cov ntaub ntawv khau:Cua cushions, outsoles, khau nto decorations, thiab lwm yam.
Zaj duab xis thiab tubing:Txawb xov tooj tiv thaiv zaj duab xis, infusion raj, pneumatic raj, thiab lwm yam.
Cov khoom siv hluav taws xob:Xov tooj Case, cable protectors, thiab lwm yam.
Automotive Cheebtsam:mudguards, tha xim sab hauv, thiab lwm yam.
LGF TPU yas pellet feem ntau yog siv nyob rau hauv daim ntawv thov uas yuav tsum tau withstanding tseem ceeb loads thiab siab zog, xws li:
Automobile structural Cheebtsam:dashboard bracket, bumper ncej, qhov rooj module, thiab lwm yam.
Industrial khoom:kis tau tus mob, bearings, cuab yeej vaj tse, thiab lwm yam.
Cov khoom ua si:Tsheb kauj vab pedals, caij ski board qhov chaw, thiab lwm yam.
TPU (thermoplastic polyurethane) thiab LGF TPU (ntev iav fiber ntau reinforced thermoplastic polyurethane) yog ob qho tib si polyurethane-raws li cov ntaub ntawv hauv cov khoom siv polymer. Cov fibers ntev nyob rau hauv LGF TPU cov ntaub ntawv tsim ib lub zog siab thiab siab rigidity peb -thav duab network nyob rau hauv cov khoom, ho txhim khu cov khoom tensile zog, khoov modulus, thiab seem stability. Yog li ntawd, nyob rau hauv cov ntaub ntawv uas yuav tsum tau lub teeb yuag, siab load- bearing muaj peev xwm, thiab tej yam toughness, xws li automotive qhov chaw thiab industrial cov khoom vaj tse, LGF TPU composite yog ib qho zoo tagnrho lwm txoj rau cov tsoos hlau los yog iav fiber reinforced nylon. Hauv cov ntsiab lus, TPU tsom rau kev ua haujlwm yooj yim, thaum LGF TPU hais txog kev ua haujlwm nruj. Qhov kev xaiv ntawm ob yog nyob ntawm cov ntsiab lus tseem ceeb rau cov khoom siv kho tshuab ntawm cov khoom kawg.
Txhaj Molding:
Vim muaj cov iav fiber ntau ntev, kev txhaj tshuaj molding ntawm LGF TPU polyester yuav tsum tau tshwj xeeb kev txiav txim siab los tswj qhov ntev ntawm cov fibers, yog li xyuas kom meej qhov kev ua tau zoo ntawm cov khoom kawg.
Screw tsim:Nws raug nquahu kom siv cov ntsia hlau uas tsis tshua muaj zog los tiv thaiv cov shearing ntau dhau thaum txheej txheem plasticization, uas tuaj yeem ua rau cov iav fibers tawg.
Pwm kub:Kev tuav lub pwm kub kub tuaj yeem txhim kho cov khoom siv fluidity, txo qhov kev hloov pauv ntawm fiber ntau orientation, thiab yog li txo qhov anisotropy ntawm cov khoom.
Txhaj ceev:Nws raug nquahu kom siv qhov nruab nrab mus rau qis qis kom tsis txhob muaj zog shear ntau dhau.
Rooj vag tsim:Nws raug nquahu kom siv loj- qhov loj me thiab qis- cov rooj vag shear hom, xws li kiv cua- zoo li tus los yog daim ntawv - zoo li lub rooj vag, los pab txhawb kev sib sau ntawm cov fibers.
