Tsis muaj ntxhiab tsw hluavtaws tawvsiv DMF-dawb, dej-yug los yog 100% khoom polyurethane matrix kom tshem tawm cov volatile organic compound (VOC) tshem tawm-gassing. Los ntawm kev hloov cov tshuaj halogenated cov kuab tshuaj nrog cov aqueous dispersions, WINIW International Co., Limited lav qhov nruj VDA 270 tsw qhov ntsuas tsawg dua lossis sib npaug rau Qib 2.0, lub cev tiv thaiv pungent tshuaj emissions nyob rau hauv kaw tsheb thiab sab hauv ib puag ncig.
Khoom Description
Txheem hnyav-raws li polyurethane (PU) tso siab rau Dimethylformamide (DMF) thiab toluene kom yaj cov polymer resin ua ntej txheej polyethylene terephthalate (PET) fiber puag. Thaum lub sij hawm 150℃thermal curing theem, cov kuab tshuaj vaporize, tab sis 500-1500 ppm ntawm DMF inevitably tseem nyob rau hauv lub micropores ntawm lub substrate. Qhov no residue ua rau qhov txawvtshuaj tsw qab faux tawvCov khoom pov thawj thaum unboxing, nquag tso tawm cov pa phem huab cua (HAPs) thaum raug UV hluav taws xob lossis chav tsev kub siab tshaj 50 degree.
Txhawm rau tshem tawm cov tshuaj tiv thaiv tshuaj no, QA cov thawj coj soj ntsuam pebCov khoom tshwj xeeb]cov khoom siv leverage peb cov txheej txheem aqueous coagulation nruj. Txoj kev no hloov cov kuab tshuaj lom nrog cov ntshiab H₂O thaum lub sij hawm thawj cov tshuaj tiv thaiv. Cov txiaj ntsig tau poob qis DMF mus rau qhov tsis yog - kuaj pom 0 ppm, ua kom ntseeg tau ncaj qha raws li EU REACH Annex XVII SVHC txwv tsis pub ua kom tsis zoo rau ISO 2411 tev lub zog (Ntau dua lossis sib npaug li 30 N / 3cm).
VDA 277 Emission Benchmarks rau Sab Hauv Tsev thiab Auto Applications
Hloov mus rau akuab tshuaj-dawb microfibertiv thaiv olfactory tsis ua hauj lwm nyob rau hauv siab - kawg daim ntawv thov kev lag luam. Nyob rau hauv cov chaw kaw, tshwj xeeb tshaj yog nyob rau hauv lub tsheb sector, residual VOCs outgas thiab condense ntawm iav qhov chaw, tsim loj tha xim sab hauv cua fogging (DIN 75201) thiab inducing tib neeg ua pa irritation.
Kev ntsuam xyuas kev ua raws li OEM yuav tsum tau kuaj xyuas cov thermal emission puas. Cov matrix hauv qab no qhia txog qhov tshwj xeeb outgassing profiles ntawm tus qauv hnyav-raws li PU tiv thaiv peb cov dej engineering- yug los ntawm architecture.
| Testing Protocol | Solvent-Raws li PU | Dej-Borne Microfiber | Automotive Standard |
| Kev ntsuas qhov tsw (VDA 270, 80 degree) | Qib 4.5 (Muaj zog, ntxhov siab) | Qib 2.0 (Perceptible) | Tsawg dua lossis sib npaug rau Qib 3.0 |
| Tag Nrho VOC Emissions (VDA 277) | >300 ugC/g | Tsawg dua lossis sib npaug li 10 ugC / g | Tsawg dua lossis sib npaug li 50 ugC / g |
| DMF Residue (EN 16778) | >500 mg/kg | 0 mg/kg | Tsis yog - kuaj pom |
| Fogging Test (DIN 75201-B) | >2.5 mg (hnyav) | < 0.5 mg (Clear) | Tsawg dua lossis sib npaug li 1.0 mg |
| Peeling zog (ISO 2411) | Tsawg dua los yog sib npaug li 15 N / 3cm | Ntau dua lossis sib npaug li 30 N / 3cm | Ntau dua lossis sib npaug li 25 N / 3cm |
Qhov kev coj dawb huv no tswj hwm lub hiav txwv 3D -Island PET matrix kom zoo thaum ua raws li cov kev txwv Tsheb Sab Hauv Huab Cua Zoo (VIAQ). Rau kev nruam OEM kev yuav khoom, tshuaj xyuas peb cov txheej txheem tshwj xeeb thiab emission tswj tsis ncaj qha ntawm pebAutomotivecov ntaub ntawv technical hub.
Cov lus nug nquag
Q: Vim li cas tus qauv hluavtaws tawv tsw tsw phem?
A: Txheem PU siv cov kuab tshuaj halogenated xws li Dimethylformamide (DMF) thiab toluene rau resin coagulation. Tsis tiav thermal curing ntxiab cov volatile organic compounds (VOCs) nyob rau hauv cov ntaub ntawv matrix, ua rau lawv tsis tu ncua tawm - roj ib tug pungent tshuaj tsw qab ntawm chav tsev kub.
Q: Yuav ua li cas hnyav -dawb microfiber tshem tawm tsw?
A: Nws hloov cov kuab tshuaj lom nrog dej -ua rau polyurethane dispersions. Los ntawm kev siv H₂O raws li qhov nruab nrab coagulation thaum lub sijhawm tsim khoom, nws tawm xoom seem DMF (0 ppm), ua kom cov substrate ncaj qha hla nruj VDA 270 kev ntsuas tsw (tsawg dua lossis sib npaug rau Qib 2.0).
Q: Puas yog tsw ntxhiab hluavtaws tawv haum rau lub tsheb sab hauv?
A: Yog. Kev tshem tawm VOCs ua kom cov khoom dhau DIN 75201 fogging tests (< 0.5 mg) and VDA 277 emission limits (≤ 10 μgC/g). This prevents windshield condensation and maintains safe Vehicle Interior Air Quality (VIAQ) in high-temperature cabins.
