Cov khoom siv ntawm PVC Windows
PVC qhov rais tsis yog cov yas ntshiab lossis cov hlau ntshiab, tab sis yog cov qauv sib xyaw zoo li cov qhaub cij:
Txheej txheej: Siab-lub zog PVC yas, tiv taus kev laus thiab muaj ntau yam xim
Core: Muab galvanized steel thav duab, muab cov qauv tsim muaj zog
Txoj Kev Sib Koom: Cov hlau yog tag nrho hauv cov yas, tiv thaiv kev sib cuag nrog huab cua
Cov qauv tsim no khaws cov kev tiv thaiv corrosion ntawm cov yas thaum muaj cov khoom thauj -cov kabmob muaj peev xwm ze rau ntawm cov hlau, xws li muab cov yas tiv thaiv rau ntawm lub thav duab steel.
Vim li cas lub qhov rais steel -plastic composite xav tau?
Cov kev xav tau muaj zog: Pure PVC yuav khoov qhov ntev tshaj li 2 meters, thaum ntxiv cov hlau tso cai rau 4-meter ncua yam tsis muaj deformation.
Kub adaptability: Hlau offsets lub thermal expansion thiab contraction ntawm yas, tuav lub kaw ntom nti ntawm -30℃mus rau 70 degree.
Tus nqi sib npaug: Txuag 40% ntawm cov nqi piv rau cov qhov rais ntshiab, thiab yog 60% sib zog dua li cov qhov rais ntshiab.
Kev sib piv nrog lwm lub qhov rooj thiab qhov rais
vs Aluminium alloy qhov rais: PVC muaj ob zaug lub rwb thaiv tsev tab sis yog me ntsis qaug zog.
vs Khoom ntoo qhov rais: Kev tu-dawb thiab ya raws- pov thawj, tab sis tsis muaj qhov zoo nkauj ntawm ntoo.
vs Ntshiab steel qhov rais: daws qhov teeb meem ntawm condensation thiab xeb nyob rau hauv steel qhov rais.
vs Pure yas qhov rais: Txhim kho cua siab tiv thaiv los ntawm 3 qib.
