Nruam -Cov khoom siv rau lamination ntxiv
PET Continuous Filament Nonwoven yog tsim los ntawm kev tso cov tub ntxhais ncaj qha - sheath nruam filaments rau hauv lub vev xaib. Nws tsis xav tau cov xov paj zoo sib xws lossis warp-thiab-weft weaving.
Qhov ntev ntawm filament yog tas mus li. Los ntawm kev kho filament fineness, web density, thiab koob - punching theem, cov khoom yuav raug tsim nrog txawv lub hauv paus luj, thicknesses, porosity theem, thiab huab cua -permeability qhov tseem ceeb.
Piv nrog rau cov filament tas li xav tau tsim tshwj xeeb tshaj yog rau kub - nias cov khoom siv, cov khoom no muab qhov tseem ceeb rau qhov sib xws ntawm qhov chaw, airflow, thiab kev sib raug zoo nrog cov txheej txheem lamination.
Nws tuaj yeem muab tau los ua lub teeb yuag uas tsis yog woven substrate los yog ua ke nrog cov kev xav mos, kev xav tsis zoo, aluminium ntawv ci, thiab lwm yam txheej txheem ua haujlwm.
Fine Filament and Air -Permeability Control
High- qib tsheb kawg tuaj yeem siv cov hlua zoo ntawm 2.2–3.3 dtex nrog txoj kab uas hla ntawm 14–20 μm. Cov filaments zoo no pab tsim kom muaj qhov smoother thiab ntau dua qhov chaw.
Qhov hnyav nruab nrab ntawm 150 mus rau 2,000 g / m², thiab thickness yog li ntawm 3 mus rau 50 hli. Qhov dav yog muaj los ntawm 1.0 mus rau 4.2 m, nrog yob ntev ntawm 50-200 m.
Porosity yog 85% -98%. Ntawm qhov sib txawv ntawm 200 Pa, huab cua permeability tuaj yeem hloov kho ntawm 100 thiab 1,500 L / (m²·s).
Tsawg-pab- cov khoom hnyav feem ntau muab cov cua ntws ntau dua. Ua kom lub hauv paus hnyav thiab rab koob ntom ntom ua rau lub ntsej muag nruj dua, muaj zog dua qhov ruaj khov, thiab zoo sib xws nrog tom qab lamination.
Qhov no tso cai rau cov khoom siv sib txuam rau cov qauv acoustic sib txawv hauv cov tsheb sab hauv.
Cov ntaub ntawv tsim khoom thiab cov ntaub ntawv khoom siv
LMPET sheath extrusion kub yog 245-260 degree, thaum PET core extrusion kub yog 290-296 degree. Sab- cua ceev yog 0.45 m / s, thiab winding ceev yog 3,500-4,500 m / min.
Nruam spinning thiab ncaj web nteg txo tus naj npawb ntawm cov fibers luv luv thiab pab tswj kom muaj kev ncaj ncees.
PET Continuous Filament Nonwoven siv PET sheath thiab PET core. Nws tsis siv PU nplaum, phenolic resin, lossis epoxy resin ua cov khoom sib txuas.
Formaldehyde emission tsis ntau tshaj 15 ug / (m²·h), tag nrho VOC carbon tsis ntau tshaj 50 ugC / g, thiab tsw qib tsis ntau tshaj 3.5.
Cov khoom ua tau raws li RoHS, REACH, thiab ELV cov cai thiab tuaj yeem txhawb 100% ib zaug - khoom siv PET rov ua dua.
Automotive Siv thiab Roll Inspection
Cov khoom no yog tsim rau automotive headliner acoustic khaubncaws sab nraud povtseg, qhov rooj- vaj huam sib luag liner, A/B/C pillar filling, trunk side- vaj huam sib luag linings, thiab nruam-filament substrates rau mos- thiab - nruj composite acoustic Cheebtsam.
Jiangsu Haokai tuaj yeem tsim cov khoom siv raws li qhov xav tau dav, qhov hnyav, thickness, airflow, thiab tom qab lamination txoj kev.
Lub tuam txhab txhawb nqa yob sampling, tuag- txiav kev sim, thiab ntim khoom. Cov txheej txheem tswj npog cov ntxhiab tsw, VOCs, fogging, qhov sib xws, thiab siab - thiab qis - qhov kub thiab txias rau kev siv tsheb.
Kev nce qib ntawm kev tsim khoom tuaj yeem muab tau thaum lub sijhawm tsim khoom. Ntim tuaj yeem xaiv raws li txoj kab uas hla yob, yob ntev, thiab kev thauj mus los.
Txhua yob tau txais 100% kev tshuaj xyuas ua ntej packing, thiab thib peb -kev soj ntsuam tog tau txais yog li cov neeg yuav khoom tuaj yeem txheeb xyuas cov txheej txheem yob thiab cov khoom sib xws.
