Thaum xaiv modifiers rauspunbond nonwoven ntaubCov ntaub ntawv raw, cov laj thawj hauv qab no yuav tsum tau ua raws li: "ua ntej qhov tseem ceeb ntawm cov kev xav tau ntawm daim ntawv thov scenario → yoog rau kev ua haujlwm / kev tiv thaiv ib puag ncig → sib npaug sib npaug thiab tus nqi → ua tiav daim ntawv pov thawj," precisely phim cov kev xav tau ntawm kev ua haujlwm nrog cov ntawv thov tiag tiag.
Txheeb xyuas cov kev xav tau tseem ceeb ntawm qhov xwm txheej (Kev txiav txim siab ua haujlwm ntawm kev hloov kho)
Ua ntej, qhia meej txog qhov tseem ceeb tshaj plaws ntawm kev ua haujlwm ntawm qhov xwm txheej thiab tshem tawm cov xwm txheej thib ob.
Yog tias qhov xav tau tseem ceeb yog "kua kua muag / kev puas tsuaj": Ua ntej cov neeg ua haujlwm toughening (POE, TPE) lossis inorganic fillers (nano-calcium carbonate).
Yog tias qhov xav tau tseem ceeb yog "anti-adsorption / antistatic": Tsom ntsoov rau cov tshuaj tiv thaiv kab mob (carbon nanotubes, quaternary ammonium ntsev).
Yog tias qhov xav tau tseem ceeb yog "sterile / kab mob": ncaj qha xaiv cov tshuaj tua kab mob (silver ions, graphene).
Yog tias qhov kev xav tau tseem ceeb yog "ib puag ncig tus phooj ywg / degradable": Tsom ntsoov rau biodegradable agents (PLA, PBA).
Yog tias qhov xav tau tseem ceeb yog "kev tiv thaiv hluav taws kub / kub tsis kam": Ua ntej cov nplaim hluav taws kub (magnesium hydroxide, phosphorus-nitrogen raws li).
Kho cov kev xav tau raws li cov ntsiab lus siv tshwj xeeb ntawm qhov xwm txheej.
Rau cov xwm txheej rov siv tau / rov ua kom tsis muaj kab mob: Xaiv cov khoom siv ntxhua khaub ncaws uas siv tau ntev (xws li polyether-based antistatic agents, phosphorus-nitrogen raws nplaim hluav taws xob).
Rau qhov kub-kub/siab-kub ib puag ncig: Xaiv qhov kub thiab txias-adaptive modifiers (rau kev siv kub tsawg). EVA (High-Temperature Nano-Silica)
Daim tawv nqaij tiv tauj Scenarios: Ua ntej ntawm daim tawv nqaij-phooj ywg, tsis tshua muaj kev hloov kho (quaternary ammonium ntsev, PLA blends)
Kho kom haum rau kev ua thiab kev txwv ib puag ncig (Kev zam kev xaiv tsis ua tiav)
Matching substrate processing yam ntxwv
Polypropylene (PP) Substrate: Ua ntej POE, TPE, thiab nano-calcium carbonate; Ua haujlwm kub haum rau 160-220 ℃, zoo sib xws
Polyethylene (PE) Substrate: Haum rau EVA thiab talc; zam kev sib xyaw nrog ntau dhau polar modifiers (xws li qee cov tshuaj tua kab mob)
Degradable Substrate (PLA): Xaiv PBA thiab PLA tshwj xeeb toughening agents kom tsis txhob cuam tshuam kev ua haujlwm degradation
Sib ntsib Environmental and Use Conditions
Sterilization Scenarios (Ethylene Oxide / High-Temperature Steam): Xaiv cov tshuaj tiv thaiv kom tsis muaj menyuam (POE, nano-calcium carbonate; zam cov tshuaj tua kab mob yooj yim decomposable)
Txias Chain / Low-Temperature Scenarios: Xaiv EVA thiab TPE nrog qhov kub thiab txias toughness; zam cov kev hloov kho uas ua rau muaj qhov kub thiab txias embrittlement
Sab nraum zoov / Ntev-ntev qhov xwm txheej: Xaiv cov laus-resistant talc thiab carbon nanotubes los txhim kho kev ruaj ntseg.
Sib npaug compatibility thiab tus nqi (kom ntseeg tau tias muaj peev xwm)
Txheeb xyuas qhov sib haum xeeb ntawm kev hloov kho nrog lub substrate.
Tsis txhob cuam tshuam rau kev ua haujlwm ntws tom qab ntxiv: Piv txwv li, qhov sib ntxiv ntawm cov khoom siv inorganic yuav tsum tsis pub tshaj 5%, thiab qhov sib ntxiv ntawm elastomer modifiers yuav tsum tsis pub tshaj 3%. Tsis txhob txi qhov ua tau zoo ntawm cov tub ntxhais substrate: Piv txwv li, thaum ntxiv PLA modifiers rau PP substrates, cov nyiaj ntxiv yuav tsum tau tswj ntawm 10% -15%, ntsuas qhov toughness thiab kub tsis kam.
Ua ntej tus nqi:
Tus nqi qis (piv txwv li, cov ntaub ntawv kho mob zoo ib yam): Xaiv cov kev hloov kho tus nqi xws li talc, EVA, thiab magnesium hydroxide.
Mid-rau-high-end xwm txheej (xws li, precision ntsuas ntim, cov khoom siv high-end): Xaiv cov kev hloov kho kom zoo dua qub xws li carbon nanotubes, graphene, thiab silver ion modifiers.
Cov xwm txheej ntau lawm: Ua ntej cov kev hloov kho uas muaj qhov sib ntxiv qis thiab cov teebmeem ruaj khov (xws li nano-theem fillers, qhov ntxiv ntawm 1% -3% yog txaus).
Txheeb xyuas cov ntawv pov thawj kev ua raws cai (tsis txhob muaj kev pheej hmoo ua raws cai)
Cov xwm txheej kho mob yuav tsum ua raws li cov qauv kev lag luam sib xws.
Tiv tauj cov cuab yeej / qhov mob tshwm sim: Cov hloov kho yuav tsum dhau ISO daim ntawv pov thawj. 10993 Biocompatibility Testing (piv txwv li, nyiaj ions, PLA)
Cov khoom xa tawm: Yuav tsum ua raws li REACH, EN 13432, thiab lwm yam kev cai (tsis txhob hloov pauv uas muaj phthalates; saib xyuas qhov tseem ceeb ntawm cov nplaim taws tsis muaj halogen thiab biodegradable modifiers).
Kev Sib cuag Khoom Noj (piv txwv li, piv txwv lub hnab ntim khoom): Xaiv cov khoom noj uas muaj ntawv pov thawj (piv txwv li, zaub mov qib nano-calcium carbonate, PLA).
