Txheej txheem cej luam
Ua los ntawm TPU (thermoplastic polyurethane) elastomer, no waterproof, breathable membrane muaj siab elasticity thiab lub zog. Txawm hais tias nws qhov tuab tsawg (0.012 hli - 0.025 hli), nws muab cov dej tsis sib haum nrog lwm cov ntaub ntawv, muaj peev xwm tiv taus dej siab tshaj 10,000 hli H2O. Kev siv thev naus laus zis yog ua haujlwm los koom nrog pawg hydrophilic rau hauv zaj duab xis; Qhov no tso cai rau nws tshwj xeeb noo noo permeability, tso cai rau hws kom khiav tawm sai sai thaum lub cev ua si. Yog li ntawd, tus neeg hnav yuav txias thiab qhuav vim lub cev kub tau tswj tau zoo. Qhov kev ua haujlwm zoo no- ua ke nrog cov tshuab lamination tshuab- ua kom muaj txiaj ntsig zoo ntawm cov khoom siv textile tiav. Los ntawm kev kov yeej ntau yam kev tsis txaus ntseeg uas cuam tshuam nrog PVC thiab PU tawv, cov khoom siv no tau pom dav siv hauv skiwear, tsho tiv no, txias- tsho huab cua, hnab looj tes, kaus mom, khau, ris tsho, ris tsho, sofas, khoom ua si, strollers, thiab lev. Nrog nws zoo heev tiv thaiv txias, eco-tus phooj ywg thiab tsis yog{15}} tshuaj lom neeg, thiab recyclability / biodegradability, cov dej tsis zoo, breathable membrane tau tshwm sim los ua cov khoom tseem ceeb rau lub xyoo pua 21st.
TPU (Thermoplastic Polyurethane) yog tus paub tab, eco- cov khoom siv polymer tus phooj ywg uas muaj qhov tshwj xeeb tensile lub zog, toughness, thiab aging kuj. Kuj tseem hu ua cov dej tsis muaj dej, noo noo-permeable membrane, nws sawv cev rau kev ua haujlwm loj hauv cov dej tsis muaj dej- breathable fabric technology, kov yeej ntau qhov kev txwv cuam tshuam nrog PVC thiab PU tawv.
Nws muab cov khoom ntawm cov roj hmab thiab cov khoom siv niaj hnub nrog cov yam ntxwv zoo ntawm lub cev thiab tshuaj lom neeg, ua rau nws lub koob npe nrov ntawm "cov khoom ntawm lub neej yav tom ntej." TPU zaj duab xis yog tsim los ntawm TPU granules siv cov txheej txheem tsim tshwj xeeb.
Ua raws li cov khoom siv lub cev zoo tshaj plaws, TPU zaj duab xis muaj ntau yam kev siv. Nws yog dav siv nyob rau hauv sectors xws li kev kho mob, electronics, kev lag luam, thiab kev ua si. Hauv cov cheeb tsam xws li Europe thiab North America, TPU tau tsim los ntev rau hauv cov khoom xws li cov khoom siv tsis muaj dej tsis zoo- breathable apparel, tshwj xeeb lamination films rau khau thiab silicone lub mis, thiab TPU elastic bands.
Nws muaj kev ua tau zoo tsis sib xws-xws li lub zog siab, tawv, thiab ua haujlwm tsis zoo, txias, roj, dej, kev laus, thiab huab cua-nrog rau cov yam ntxwv zoo xws li dej tsis zoo thiab dej permeability, windproofing, txias tiv thaiv, antibacterial thiab anti{2}} pwm cov khoom, thermal rwb thaiv tsev, UV tiv taus, thiab lub zog tso tawm capabilities.
Feature
1. Txias tsis kam mus rau -30 degree;
2. Plasticizer-dawb thiab tsis yog-migratory (tsis muaj roj exudation);
3. Cov qauv molecular yooj yim (carbon, hydrogen, oxygen, nitrogen) txo cov pa phem thaum lub sij hawm incineration; ib txwm decomposes nyob rau hauv 3-5 xyoo thaum faus rau hauv av uas muaj noo noo thiab microorganisms.
Waterproof thiab breathable kev ua tau zoo specifications:
1. High breathability/moisture permeability: >6,000 g / m² · 24 h; dej tsis kam: 10,000 mm H₂O; elongation: 300% -800%.
2. Nruab nrab ua pa / noo permeability: 2,000–4,000 g/m²·24h; dej tsis kam: 10,000 mm H₂O; elongation: 300% -800%.
3. Tsawg breathability / noo noo permeability:<2,000 g/m²·24h; water resistance: 10,000 mm H₂O; elongation: 300%–800%.
Kev ua tau zoo
1. Tear Performance: Tear lub zog ntsuas cov khoom tiv thaiv kom tawg; Lub zog tsim kua muag ntawm cov dej tsis muaj dej, cov pa ua pa yog qhov zoo heev -thov ntau dua cov roj hmab thiab cov yas.
2. Abrasion Resistance: Cov ntaub ntawv feem ntau raug kev txom nyem los ntawm cov khoom siv xws li kev sib txhuam, khawb, thiab puas. Kev puas tsuaj zoo heev yog qhov tseem ceeb, thiab cov membranes muaj kev puas tsuaj li ntawm 3 mus rau 5 npaug ntawm cov roj hmab ntuj.
3. Flex Fatigue Resistance: Rau cov ntawv thov uas muaj kev ntxhov siab ntau zaus, flex kuj tseem ceeb heev. Cov membranes no tswj tau zoo heev yooj yooj yim thiab durability nyob rau hauv ib puag ncig- ua rau lawv xaiv zoo tshaj ntawm cov ntaub ntawv polymer- thiab qhia tsis muaj tawg tawm txawm tias tom qab 3 lab flex cycles.
4. Dej Resistance: Cov daim nyias nyias muaj cov dej tsis zoo nyob rau hauv chav tsev kub, uas qhia tias tsis muaj hydrolysis tseem ceeb txawm tias tom qab 1 mus rau 2 xyoos.
5. Roj thiab Tshuaj Tiv Thaiv: Raws li cov khoom siv polar polymer, lawv muaj kev sib raug zoo tsawg heev rau cov roj tsis muaj -polar ntxhia roj. Lawv zoo li tsis muaj kev cuam tshuam los ntawm cov khoom corrosive xws li roj av, roj (roj av), thiab cov roj (xws li, hydraulic kua, lubricants). Lawv ua kom pom cov roj zoo dua, nrog kev hloov pauv tsis zoo hauv ntim; tensile lub zog tej zaum yuav tshaj qhov pib qhov tseem ceeb. Txawm hais tias kev ua tau zoo tseem zoo heev piv rau lwm cov ntaub ntawv, qhov muaj cov dej noo me me hauv cov roj ntxhia tuaj yeem muaj qhov sib txawv ntawm qhov tsis zoo.
6. High-kev ua haujlwm kub: Thaum xaiv cov khoom siv rau lub sijhawm ntev- siv qhov kub siab (xws li, siab dua 70 degree), ib tus yuav tsum xav txog kev tiv thaiv atmospheric oxidation (aging); Cov dej tsis muaj dej, ua pa tsis zoo tuaj yeem tiv taus qhov hnyav hnyav thiab feem ntau muaj qhov kub thiab txias tsis kam tshaj 130 degree.
7. Tsawg-kub kev ua haujlwm: Cov daim nyias nyias muaj qhov zoo heev uas tsis tshua muaj- qhov kub thiab txias, feem ntau ua haujlwm tau qis mus rau -30℃yam tsis ua nkig, ua rau lawv tsim nyog siv rau hauv cov khoom tsim los rau qhov chaw txias.
8. Antimicrobial zog: Cov daim nyias nyias muaj cov yam ntxwv zoo ntawm cov tshuaj tua kab mob thiab tshuaj tua kab mob, tiv thaiv kev loj hlob thiab colonization los ntawm * Penicillium *, * Aspergillus *, * Aureobasidium pullulans *, spores, thiab cov neeg sib xyaw microbial.
9. Gas diffusion kev ua tau zoo: Tsim los siv ultrasonic lossis cua sov- xovxwm vuam, cov membranes no tau siv dav hauv cov khoom lag luam. Gas diffusion coefficients ntsuas tus nqi ntawm cov pa roj dhau los ntawm thaj chaw tshwj xeeb ntawm cov qauv hauv qab ntsuas kub thiab siab; diffusion tus nqi sib txawv-qee zaum tseem ceeb- nyob ntawm seb cov roj tshwj xeeb cuam tshuam. TPU-raws li waterproof, breathable membranes muaj superior sealing kev ua tau zoo.
10. Biomedical zog: Cov daim nyias nyias muaj cov biocompatibility zoo heev - tsis yog - tshuaj lom, tsis yog - ua xua, tsis yog - ua rau khaus rau cov ntaub so ntswg hauv zos, thiab pyrogen - dawb- thiab tau dav siv hauv kev kho mob, kev noj qab haus huv, thiab cov khoom tiv thaiv kev ua si.
