Qhov sib txawv rau TPE, TPU thiab PU?
TPE (thermoplastic elastomer)
TPE yog ib thermoplastic elastomer cov khoom paub rau lub zog siab, zoo elasticity, thiab kev txhaj tshuaj molding. Nws muaj ntau cov ntawv thov, yog ib puag ncig phooj ywg, tsis - pa, thiab muaj kev nyab xeeb, thiab muaj cov xim muaj txiaj ntsig zoo.
Cov Nta Tseem Ceeb Ntawm TPE:
Eco {- Tus phooj ywg, tsis - pakic, thiab muaj kev nyab xeeb
Dav hardness ntau, mos kov, huab cua zoo tsis kam, nkees tsis kam, thiab kub kuj
Kev ua tau zoo tshaj plaws - Tsis muaj Vulcanization Yuav Tsum
Tuaj yeem rov siv dua tshiab thiab siv rov qab los txo tus nqi
Tuaj yeem dhau los rau ntawm PP, PE, PC, PS, ABS, thiab lwm yam., Lossis moulded ywj siab
Qhov Zoo:
Tuaj yeem ua tiav siv cov qauv thermopastic molding tshuab {{}}} tsis muaj cov khoom siv tshwj xeeb.
Zoo heev txhim kho ntau lawm equiciency - txhaj tshuaj moulding tuaj yeem txo cov sijhawm vulcanization los ntawm ~ 20 feeb rau hauv qab 1 feeb.
Yooj yim rau kev rov ua haujlwm thiab rov siv cov khoom pov tseg thiab siv cov khoom tsis zoo, txo qhov kev cuam tshuam ib puag ncig thiab tus nqi.
Zog - txuag {- Kev noj roj hmab (piv txwv li, kev txuag roj hmab, txuag dua 25%).
Broder daim ntawv thov Field -}} makines ntawm cov txiaj ntsig ntawm roj hmab thiab yas.
Tuaj yeem txhim kho thiab ua kom nruj heev, nrog cov qauv yooj yim thiab cov khoom tau zoo.
Txawm li cas los xij, TPE cov cua sov kuj yog qis dua li roj hmab, thiab nws tau ua kom muaj kev ua tiav ntau dua kev ua haujlwm kub dua. Nws tseem muaj qhov ua tau qis dua teeb tsa tau teeb tsa, elasticity rov qab, thiab lub peev xwm piv rau cov roj hmab, thiab feem ntau kim dua.
TPU (Thermoplastic Polyurethane)
TPU yog ib hom ntawm thermoplastic polyurethane elastaur ua los ntawm MDI (Methylene diphenyanate), tdi (macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiols), macrodiools, thiab saw txuas ntxiv. TPU yog feem ntau categorized rau hauv polyester - raws thiab polyet {2} raws hom.
Cov Nta Tseem Ceeb Ntawm TPU:
Dav hardness ntau (60HA-85hd)
Cov hnav zoo heev, roj kuj, pob tshab, thiab elasticity
Siv dav hauv cov neeg siv khoom, khoom siv kis las, khoom ua si, khoom zoo nkauj, thiab lwm yam.
Halogen - i}} Flame Flame- retardant tpu tuaj yeem hloov cov muag muag muag kom zoo.
Qhov Zoo:
Cov Hnav Ncauj Kuj
Kho lub hardness nrog cov elasticity
High Txhua yam muaj zog, cuam tshuam zoo heev, thiab kev nqus kev poob siab
Zoo tshaj plaws qis - kub hloov (tseem dav hauv qab -35 degree)
Cov txheej txheem zoo - tuaj yeem ua pwm siv txhaj tshuaj, extrusion, daim ntawv qhia, muaj peev xwm ua cov polymer sib xyaw rau kev ua tau zoo
Roj -, dej -}, thiab cov pwm {{resistant
Ua tau yooj yim
PU (Polyurethane)
PU, luv luv rau polyurethane, yog cov polyurethane, yog cov polyurethane, yog cov khoom siv nhcoo - unsection tsim los ntawm etocyanate thiab hydroxyl pawg. PU yog siv dav vim nws lub khaub ncaws hnav, hnav tsis kam, softness, thiab tshuaj lom neeg kuj, txawm hais tias nws muaj qee qhov poob qis.
PU hauv kev siv:
Feem ntau siv nyob rau hauv rooj tog upholstery, xws li rooj zaum rooj plaub hau
Kuj tseem hu ua tawv tawv lossis tawv tawv
Cov yam ntxwv tseem ceeb ntawm PU:
Kev ua haujlwm lub cev zoo - ywj, khoov - tiv taus, muaj zog tensile zog, thiab breathabable
Ua Piam Zog Thiab Hehole Permeability (8000-11000g / 24h
Siab dua tus nqi - ib co Pu cov ntaub raug nqi 2-3 zaug ntau dua PVC
Cov qauv qauv rau PU DE Nthy kho kom zoo nkauj muaj kev siv tsawg (4-5 zaug), nce nqi
Cov menyuam yaus embossed siv hauv PU tsim ua lub neej ntev ntev, ua rau muaj nqi ntau dua
Cov tawv cua hluavtaws puas muaj cov tawv hluavtaws tiag tiag {{0} Zoo li kev xaiv, tab sis yog xim dub thiab xim av), thiab nws yog tus nquag rau xim fading. Lub hauv paus npuag hauv Pu muaj lub zog zoo tensile, thiab nws tuaj yeem muab tso rau lossis kos rau hauv cov khoom los nkaum txheej txheej.
