Puas yog cov yas profile ua nkig nrog lub hnub nyoog?
Plastics formulated kom zoo tswj cov qauv kev ntseeg tau ntau xyoo. UV-stabilized thiab weatherized formulations tiv thaiv degradation los ntawm tshav ntuj thiab ib puag ncig raug. Cov ntawv thov sab hauv tsev feem ntau qhia cov khoom hloov pauv tsawg tshaj li 20-30 xyoo. Sab nraum zoov profiles nrog txaus UV stabilization tswj 80-90% ntawm thawj lub zog tom qab 15-20 xyoo. Tsis txhob siv cov yas tsis ruaj khov rau hauv cov khoom siv sab nraum zoov.
Cov yas profile puas tuaj yeem hloov cov hlau hauv kev tsim kho?
Rau lub teeb rau nruab nrab ntawm cov qauv loads thiab tsis yog - cov ntawv thov tseem ceeb, yog. Yas extrusion khoom yog nyiam nyob rau hauv kev tsim kho rau durability thiab lub teeb yuag, siv nyob rau hauv lub qhov rais thav duab, doorframes, thiab ru tsev vim lawv corrosion kuj thiab yooj yim installation. Txawm li cas los xij, cov txheej txheem tseem ceeb xws li cov kab hauv tsev, hauv pem teb joists, thiab thauj khoom -cov phab ntsa tseem yuav tsum tau steel, pob zeb, lossis cov ntoo ua haujlwm. Xav txog cov yas profiles zoo heev rau cov qauv theem nrab, cov ntaub thaiv npog, thiab cov khoom siv uas muaj kev tiv thaiv corrosion thiab qhov hnyav tshaj qhov muaj zog tshaj plaws.
Qhov ntsuas kub npaum li cas tuaj yeem ua cov txheej txheem yas profile?
Txheem PVC thiab polyethylene profiles ua haujlwm ntawm -20℃txog 60℃. Iav- puv nylon txuas qhov no mus rau -40℃mus rau 120℃siv tas li. PEEK tiv taus kub txog 260℃thaum tswj cov khoom siv kho tshuab, thaum Torlon polyamide-imide tseem ruaj khov rau 260 degree. Sib phim xaiv cov khoom siv rau koj qhov kub thiab txias, nco ntsoov tias cov khoom siv hluav taws xob poob qis thaum qhov kub nce mus txog qhov kub deflection txwv.
Cov qauv kev ntseeg tau los ntawm kev paub txog kev xaiv
Extruded profiles yas xa cov qauv kev txhawb nqa thoob plaws kev nthuav dav ntawm kev siv, tshwj xeeb tshaj yog qhov kev tiv thaiv corrosion, txo qhov hnyav, lossis tsim kev yooj yim teeb meem. Lawv tsis yog universal hlau hloov tab sis theej optimized daws rau tej yam kev mob.
Tus yuam sij rau kev ua tiav yog nyob rau hauv kev sib piv cov khoom siv thiab profile geometry rau cov xwm txheej tiag tiag thiab ib puag ncig. Iav- puv polymers mus txog lub zog hlau ntawm ib feem ntawm qhov hnyav. Ntau -chamber designs tsim kom muaj kev nruj nruj los ntawm cov khoom siv tsawg. Tsim kom raug tshem tawm feem ntau hom kev ua tsis tiav.
