Marine qib faux tawvyog ib tug engineered polyurethane substrate tshwj xeeb synthesized rau yacht sab nrauv thiab pontoon zaum, integrating hindered amine light stabilizers (HALS) thiab hydrophobic fluorocarbon kev kho mob hla hiav txwv 3D -kob PET matrix. Cov qauv no nquag tiv thaiv UV-induced polymer cleavage thiab saltwater hydrolysis, tuav ib tug nruj ISO 2411 peeling zog ntawm ntau tshaj los yog sib npaug rau 30 N / 3cm nyob rau hauv hnyav maritime ib puag ncig.
UV Degradation thiab QUV Accelerated Weathering (ASTM G154)
Standard PVC thiab ester-raws li polyurethane sai embrittle nyob rau hauv tas li ultraviolet hluav taws xob thiab alkaline ntsev tsuag. High-lub zog UV photons rhuav tshem cov saw hlau polymer, ua rau cov khoom siv plasticizer tsiv teb tsaws, irreversible deg crazing (cracking), thiab pigment loj fading. Yuav kom engineers ib resilientNkoj upholstery microfiber, WINIW International Co., Limited suav nrog HALS thiab nanoscale UV absorbers ncaj qha rau hauv DMF- dej dawb-yug polyurethane slurry ua ntej lub coagulation theem.
Thaum ntsuas cov ntaub ntawv raws li ASTM G154 (QUV nrawm huab cua) ntsuas qhov ntsuas, qhov tshwj xeeb aliphatic formulation withstands> 1,000 teev ntawm kev raug UVA / UVB txuas ntxiv. Tag nrho cov xim sib txawv (ΔE) tseem nyob hauv lej tsawg dua lossis sib npaug li 1.5, tiv thaiv kom tsis txhob muaj xim daj hauv qis -tier marine zaum. Txhawm rau txheeb xyuas cov tshuaj ntxiv thiab cov txheej txheem stabilization uas siv hauv cov txheej txheem no, tshuaj xyuas pebCov khoom tshwj xeebtechnical database.
Hydrophobic Surface Modification thiab ntsev tsuag Resistance
Tshaj li photon degradation, marine ib puag ncig raug textiles mus tas li noo noo thiab saline raug. Ib qhov tseebWaterproof hluavtaws tawvyuav tsum tau ib tug structurally modified nto nro profile. Los ntawm kev siv tus ntoo khaub lig heev- txuas fluorocarbon nano- txheej thaum lub sij hawm kawg thermal curing theem (150 degree), lub kaum sab xis ntawm qhov sib cuag nce mus rau> 110℃. Qhov no ua rau corrosive ntsev thiab dej lwg thaum sawv ntxov kom hlaws thiab dov tawm tag nrho yam tsis tau nkag mus rau lub microporous core.
Qhov hydrophobic blockade no ua haujlwm nrog polyether-raws li polyurethane resins los tshem tawm cov tshuaj cleavage tshwm sim los ntawm dej khov. Cov matrix hauv qab no qhia txog qhov ua tau zoo ntawm WINIW marine microfiber tiv thaiv tus qauv coj mus muag PU.

Kev qhia txog cov khoom siv suab paj nruag tiv thaiv cov nqi them nyiaj hloov pauv rau cov neeg tsim yacht thiab cov neeg ua haujlwm tom qab muag. Vim hais tias lub sab hauv architecture mimics ntuj collagen, nws intrinsically dhau EN ISO 3377-2 tsim kua muag zog (Ntau dua los yog sib npaug rau 60 N), tiv thaiv stitched seams los ntawm rub sib nrug nyob rau hauv hnyav neeg nrog caij load thiab dynamic yoj cuam tshuam. Xa koj cov pob khoom CAD tech thiab ntsuas pebMarine qib faux tawvlab-dip cov qauv txhawm rau txhawm rau hauv koj qhov BOM cov lus qhia.
Cov lus nug nquag nug (FAQ)
Q: Dab tsi ua rau marine qib faux tawv resistant rau UV rays?
A: It utilizes aliphatic polyether polyurethane compounded with hindered amine light stabilizers (HALS). This chemical structure prevents photon-induced polymer cleavage, allowing the material to pass >1,000 teev ntawm ASTM G154 QUV kuaj yam tsis muaj kev sib tsoo lossis xim hnyav fading (ΔE Tsawg dua lossis sib npaug rau 1.5).
Q: Yuav ua li cas lub nkoj upholstery microfiber tuav dej ntsev raug?
A: Lub substrate tau txais fluorocarbon nano- txheej uas hloov lub kaum sab xis ntawm qhov chaw mus rau> 110 degree, ua rau nws nruj me ntsis hydrophobic. Qhov no lub cev thaiv cov alkaline ntsev nkag thiab tom qab hydrolysis, kom ntseeg tau tias ISO 2411 tev lub zog tseem muaj ntau dua lossis sib npaug li 30 N / 3cm hauv cov dej hiav txwv.
Q: Puas yog waterproof hluavtaws tawv tiv thaiv pwm thiab mildew?
A: Yog. Ntxiv nrog rau qhov dej tsis zoo, ASTM G21 ua raws cov tshuaj tiv thaiv kab mob sib xyaw ua ke ncaj qha rau hauv polyurethane resin. Qhov no zoo inhibits kev loj hlob ntawm pwm, mildew, thiab marine liab staining kab mob nyob rau hauv lub hiav txwv 3D - Island non-woven core.
