Kev tsom xam dav ntawm TPU Pellet Hardness: Cov kev ntsuas, kev siv thiab kev ceev faj rau kev siv

TPU (Thermoplastic Polyurethane), raws li lub siab - Kev ua tau zoo elastomer khoom, lub zog ntawm nws cov pelastomer cov khoom siv uas txiav txim cov khoom siv thiab daim ntawv thov kev kawm. Lub hardness ntau ntawm TPU pellets yog qhov dav heev, feem ntau yog xws li ultra- Lub cev muaj qib 70T:Qhov siab dua lub hardness, qhov muaj zog dua lub rigidity thiab deformation tiv taus ntawm cov khoom, tab sis qhov hloov tau thiab elasticity yuav txo qis; Ntawm qhov tsis sib xws, qis {{- hardness TPU tsom xam ntau dua ntawm kev softness thiab elastic rov qab.

Hais txog ntawm kev ntsuas tawv tawv, ntug dej hiav txwv tsis muaj kev siv hauv kev lag luam rau kev sim. Ntawm lawv, ntug dej hiav txwv yog tsim nyog rau qhov nruab nrab thiab qis}}}}}}}}}}}}} 9, {{}} 95A} 95A} 95A} 95A} 95A} 95A} 95A} 95A} 95A} Nruj me ntsis ua raws cov txheej txheem cov qauv thaum ntsuas: ua ntej, txhaj tshuaj TPU rau hauv cov npoo tsis xws luag xws li npuas thiab khawb; Tom qab ntawd cia cov kev kuaj xyuas cov khoom sawv ntsug hauv ib puag ncig nrog kub ntawm 23 qib ± 2% ± 5% rau 24 teev. Tom qab cov ntawv xeem yog ruaj khov, nias lub indenter kab ntsug ntawm cov npoo ntawm daim xeem, khaws nws rau 3 vib nas this thiab tom qab ntawd nyeem cov nqi. Rau txhua pawg ntawm cov qauv, ntsuas tsawg kawg 5 ntsiab lus thiab coj qhov nruab nrab los txo qhov yuam kev.

TPU PelletsNtawm txawv hardness muaj kev faib tawm meej ntawm kev ua haujlwm hauv cov ntawv thov:

Hauv qab 604 (ultra-} mos): Vim lawv zoo heev kov thiab elasticity, lawv feem ntau siv nyob rau hauv cov khoom uas muaj cov khoom ua si rau cov menyuam yaus, decomression tuav khoom pob, thiab cov tseem muaj cov linings;

60a-70a (muag): Ntsuas kev sib raug zoo thiab hnav tsis kam, nws yog cov khoom siv uas zoo tshaj plaws rau cov kis las khau, cov dej tsis muaj plua plav ib ncig thiab lwm yam khoom;

70a -} 80a (nruab nrab-muag): Nrog rau kev ua tau zoo heev, nws yog dav siv hauv cov xwm txheej xws li cable sheaths, thiab kev sib tw kev kho mob;

80a {- 95A (nruab nrab-nyuaj rau nyuaj): Ntsuas kev sib tw thiab tawv, nws yog qhov tsim nyog rau cov khoom siv uas yuav tsum muaj qee yam kev lag luam rollers, cov cuab yeej ua si hauv xov tooj ntawm tes;

Saum toj no 95a (ultra-} nyuaj): Muaj lub zog siab thiab kev cuam tshuam tsis kam, nws tau dhau los ua cov khoom siv uas nyiam dua rau cov khoom siv, cov ntaub ntawv siv tshuab, thiab cov khoom hnyav thiab cov khoom hnyav.

Thaum siv TPU Pellets, cov ntsiab lus hauv qab no yuav tsum tau sau tseg:

Tshuaj Muaj Tshuaj Ntau: TPu yog rhiab rau cov polar cov kuab tshuaj (xws li dej cawv, acetone) thiab muaj zog acids thiab alkalis. Tiv tauj nrog lawv tuaj yeem ua rau o lossis tawg, yog li nws yuav tsum tau zam hauv qhov chaw ib puag ncig zoo li no;

Tswj Qhov Kub: Lub ntev {- siv siv qhov kub yuav tsum tsis pub dhau 80 degree. Kev kub siab yuav ua kom cov laus laus ntawm cov khoom. Yog tias siv nyob rau hauv high -} -} {Resistant additives yuav tsum tau siv;

Kev Cia: Cov khoom siv tau hygroscopic thiab yuav tsum muab cia rau hauv ib lub kaw, qhuav thiab muaj qhov chaw muaj cua nrog cov av noo tswj ntawm 40%--60%. Ua ntej siv, nws yuav tsum tau qhuav nyob rau hauv ib qho 80℃qhov cub rau 4-6 teev los tiv thaiv bubles thaum ua;

Zauv tshuaj: TPU ntawm cov tawv tawv txawv yuav tsum tau phim cov txheej txheem tshwj xeeb. Piv txwv li, ultra -} Hard TPu yuav tsum nce lub chim chim rau 210-230℃thaum lub sij hawm txhaj tshuaj TPU yuav tsum tau txo cov eeb kom tsis txhob muaj eeb.
