Zipper Track Retractable Screens: Blowout Resistance nyob rau hauv siab - Cua Zones
Zipper track retractable cov ntxaij vab tshaus raug soj ntsuam nyob rau hauv peb yam tsis muaj: zipper hniav tensile rub lub zog (N / cm), taug qab tuav peev xwm nyob rau hauv cua loads txog 100 km / h, thiab PVC ntug weld kev ncaj ncees nyob rau hauv siab - zaus sealing tej yam kev mob. Nyob rau hauv windproof screen mesh systems, tsis ua hauj lwm feem ntau tshwm sim ntawm lub zipper interface ua ntej mesh rupture.
Rau nag xob nag cua qhov screen lag luam wholesale B2B daim ntawv thov, kev ua haujlwm ruaj khov yog txhais los ntawm kev tuav ruaj ruaj ntau dua lossis sib npaug li 35-60 N / cm nyob ntawm qhov dav dav thiab kev teeb tsa rigidity.

Track nruj nce linearly nrog extrusion phab ntsa thickness (1.2-2.0 mm range)
Lub kaum pob qij txha suav rau ~ 60% ntawm qhov system tsis ua haujlwm nyob rau hauv cov cua kub siab
Nruab nrab -Txoj Kev Ua Haujlwm Kev Sib Koom Tes
Nyob rau theem no, kev ua haujlwm cua tsis zoo yuav tsum tau ua kom zoo nrog cov kab noj hniav extrusion thiab zipper integration geometry rau ntev -span retractable systems.
Rau OEM thiab nag xob nag cua- ntsuas kev xa tawm:
► [windproof retractable screen qhov rooj]
Kev sib raug zoo ntawm zipper rub lub zog thiab taug qab kev muaj peev xwm txo qis qhov tsis ua haujlwm ntawm qhov nce mus txog 38% hauv thaj chaw hauv ntug dej hiav txwv.
4. Extrusion Cavity Depth Specifications rau Zipper Integration
Aluminium extrusion geometry ncaj qha cuam tshuam rau zipper zaum ruaj khov thiab mesh kev sib raug zoo nyob rau hauv cyclic cua load.

3 Cua Tolerance FAQs
Dab tsi cua ceev tuaj yeem zipper taug qab cov ntxaij vab tshaus tuaj yeem tiv taus hauv kev lag luam kev teeb tsa?
Standard industrial systems lis 60-80 km / h. Kev txhawb zog nag xob nag cua- qib tshuab tsim nrog Ntau dua lossis sib npaug ntawm 50 N / cm zipper lub zog thiab cov kev siv zog ntxiv tuaj yeem tiv taus txog 100–120 km / h nyob ntawm qhov dav dav.
Vim li cas zipper taug qab cov ntxaij vab tshaus poob ntawm cov npoo es tsis txhob ntawm cov mesh?
Kev ua tsis tiav feem ntau tshwm sim ntawm zipper cov ntsiab lus sib koom los yog cov ces kaum extrusion vim tias cov cheeb tsam no muaj kev ntxhov siab. Mesh cov ntaub ntawv feem ntau tshaj 150-200 N / cm tensile muaj peev xwm, siab dua cov khoom sib txuas.
Puas yog nce qhov tob tob txhim kho cua tiv thaiv?
Yog lawm. Ua kom cov kab noj hniav extrusion qhov tob ntawm 5 hli mus rau 8 hli txhim kho zipper tuav quab yuam los ntawm ~ 25-40% vim kev txhim kho cov khoom siv xauv thiab txo cov zipper txav mus.
