Thermoplastic Polyurethane (TPU) yog ib yam khoom siv tau ntau yam uas paub txog nws qhov ruaj khov thiab kev ywj pheej. Txawm li cas los xij, hauv qee qhov kev siv, tej zaum yuav muaj qhov xav tau los txo qhov nyuaj ntawm TPU granules thaum tib lub sijhawm txhim kho kev tiv thaiv kev puas tsuaj.
Cov tswv yim los ua kom tiav txo qhov nyuaj ntawm TPU thiab txhim kho qhov sib npaug ntawm kev tiv thaiv kev sib txhuam.
1. Kev Sib Xyaws Nrog Cov Khoom Siv Mos Mos
Ib txoj hauv kev yooj yim tshaj plaws los txo qhov nyuaj ntawm TPU yog los ntawm kev sib xyaw nrog cov khoom siv thermoplastic uas mos dua. Cov kev xaiv feem ntau suav nrog TPE (Thermoplastic Elastomers) thiab cov qib mos dua ntawm TPU.
Kev xaiv cov khoom siv mos dua thiab qhov sib piv uas nws sib xyaw nrog TPU tuaj yeem pab ua tiav qib kev txo qhov nyuaj.
2. Ib Txoj Kev Tshiab: Kev Sib Xyaws TPU Cov Khoom Siv Nrog Cov Khoom Siv Mos Si-TPV Tshiab
Kev sib xyaw ua ke ntawm 85A TPU granules nrog SILIKE tau tsim cov khoom siv mos Si-TPV (dynamic vulcanizate thermoplastic Silicone-based elastomer), Txoj kev no ntaus qhov sib npaug ntawm qhov nyuaj txo qis thiab kev tiv thaiv kev puas tsuaj ntxiv, yam tsis muaj kev cuam tshuam rau nws lwm yam khoom zoo.
Txoj kev los txo qhov nyuaj ntawm cov khoom TPU, Cov mis thiab kev ntsuam xyuas:
Qhov ntxiv ntawm 20% Si-TPV rau qhov Hardness ntawm 85A TPU txo qhov hardness mus rau 79.2A
Lus Cim:Cov ntaub ntawv xeem saum toj no yog peb cov ntaub ntawv xeem ua haujlwm hauv chaw kuaj mob, thiab tsis tuaj yeem nkag siab tias yog kev cog lus ntawm cov khoom no, tus neeg siv khoom yuav tsum tau kuaj raws li lawv tus kheej tshwj xeeb.
Txawm li cas los xij, kev sim nrog cov sib xyaw sib txawv yog qhov tshwm sim, lub hom phiaj yog kom ua tiav qhov kev sib xyaw ua ke zoo tshaj plaws ntawm kev mos thiab kev tiv taus kev sib txhuam.
3. Siv Cov Khoom Siv Uas Tiv Thaiv Kev Sib Txhuam
Yuav kom txhim kho kev tiv thaiv kev sib txhuam, cov kws tshaj lij pom zoo kom siv cov khoom tshwj xeeb xws li carbon dub, iav fibers, silicone masterbatch, lossis silicon dioxide. Cov khoom no tuaj yeem txhawb nqa TPU cov khoom tiv thaiv kev hnav.
Txawm li cas los xij, yuav tsum tau xav txog qhov ntau thiab tsawg ntawm cov khoom no, vim tias qhov ntau dhau yuav cuam tshuam rau qhov yooj ywm ntawm cov khoom.
4. Cov Tshuaj Yas thiab Cov Tshuaj Mos
Ua ib txoj hauv kev los txo qhov nyuaj ntawm TPU, cov chaw tsim khoom TPU yuav siv cov tshuaj yas lossis cov neeg sawv cev ua kom mos. Nws yog ib qho tseem ceeb uas yuav tsum xaiv cov tshuaj yas uas tsim nyog uas tuaj yeem txo qhov nyuaj yam tsis muaj kev cuam tshuam rau kev tiv thaiv kev sib txhuam. Cov tshuaj yas feem ntau siv nrog TPU suav nrog dioctyl phthalate (DOP) thiab dioctyl adipate (DOA). Yuav tsum tau ceev faj kom ntseeg tau tias cov tshuaj yas xaiv tau sib xws nrog TPU thiab tsis cuam tshuam rau lwm yam khoom xws li lub zog tensile lossis tshuaj tiv thaiv. Tsis tas li ntawd, Cov tshuaj ntawm cov tshuaj yas yuav tsum tau tswj hwm kom zoo kom tswj tau qhov sib npaug xav tau.
5. Kev Kho Kom Zoo thiab Kev Ua Haujlwm ntawm Extrusion
Kev kho cov txheej txheem extrusion thiab cov txheej txheem ua haujlwm yog qhov tseem ceeb hauv kev ua tiav qhov kev sib xyaw ua ke ntawm kev txo qhov nyuaj thiab kev tiv thaiv kev sib txhuam zoo. Qhov no suav nrog kev hloov kho cov txheej txheem xws li kub, siab, thiab tus nqi txias thaum lub sijhawm extrusion.
Qhov kub qis dua thiab kev txias ua tib zoo tuaj yeem ua rau TPU mos dua thaum ua kom zoo dua qhov kev sib kis ntawm cov khoom siv tiv taus kev puas tsuaj.
6. Cov Txuj Ci Tom Qab Ua Haujlwm
Cov txheej txheem tom qab ua tiav xws li annealing, stretching, lossis txawm tias kev kho qhov chaw tuaj yeem ua rau kom tsis txhob xeb ntxiv yam tsis muaj kev cuam tshuam rau qhov nyuaj.
Kev ua kom sov, tshwj xeeb, tuaj yeem txhim kho cov qauv crystalline ntawm TPU, ua rau nws tiv taus kev hnav thiab tsim kua muag.
Xaus lus, kev ua tiav qhov sib npaug ntawm TPU qhov nyuaj txo qis thiab kev txhim kho kev tiv thaiv kev sib txhuam yog ib qho txheej txheem ntau yam. Cov chaw tsim khoom TPU tuaj yeem siv cov khoom xaiv, kev sib xyaw, cov khoom siv tiv thaiv kev sib txhuam, cov yas ua kom yas, Cov Neeg Sawv Cev Mos, thiab kev tswj hwm qhov tseeb ntawm cov txheej txheem extrusion los kho cov khoom siv kom haum rau cov kev xav tau tshwj xeeb ntawm ib daim ntawv thov.
Qhov no yog qhov koj xav tau Ib qho mis yeej uas txo TPU Particle Hardness thiab txhim kho Abrasion Resistance!
Tiv tauj SILIKE, Peb Si-TPV pab koj ua tiav qhov mos mos zoo tagnrho, yooj ywm, ruaj khov, qhov cuam tshuam ntawm qhov chaw, thiab lwm yam khoom tseem ceeb rau koj cov khoom TPU uas ua los ntawm cov khoom me me!
