Cov ntsiab lus muag khoom tseem ceeb thiab kev ua haujlwm ntawm PVC Air Ducts

PVC cua ducts tau siv dav hauv ntau qhov chaw vim lawv cov khoom tshwj xeeb. Ua ntej, cov khoom siv PVC muaj kev tiv thaiv zoo heev, tiv thaiv kev yaig ntawm cov tshuaj xws li acids, alkalis, thiab ntsev, ua rau nws tshwj xeeb tshaj yog haum rau cov av noo lossis corrosive gas ib puag ncig. Qhov thib ob, PVC cov cua ducts yog lub teeb yuag tsis tau siab - lub zog, nrog qhov ceev tsuas yog 1/5 ntawm cov khoom siv hlau hlau, thaum tuav lub zog tensile ntawm ntau tshaj 30MPa, txo lub tsev load thaum ua kom muaj kev ruaj ntseg ntawm cov qauv. Thirdly, installation yog tshwj xeeb tshaj yog yooj yim, nrog ib tug qauv duct ntev ntawm 4 meters, siv lub qhov (socket) kev twb kev txuas los yog tshwj xeeb adhesive bonding, kev tsim kho efficiency ntau tshaj 40%. Thib plaub, lawv muaj kev ua tau zoo ntawm ib puag ncig, nrog rau kev siv hluav taws xob tsuas yog 1/3 ntawm cov hlau cua ducts thiab tus nqi rov ua dua ntawm 85%. Fifthly, PVC cua ducts, tsim los ntawm ntau-txheej txheej co- txheej txheem extrusion, muaj suab rwb thaiv tsev thiab suab nrov txo kev ua haujlwm, thiab lawv cov qauv tsim phab ntsa du txo cov cua ntws los ntawm 15%. Thaum kawg, lawv lub neej ua haujlwm ntev li 20-30 xyoo, thiab tag nrho cov nqi kho mob yog 60% qis dua cov khoom siv ib txwm muaj. Cov yam ntxwv no ua rau PVC cua ducts muaj txiaj ntsig zoo hauv cov tshuab ua pa rau cov nroj tsuag, cov tsev lag luam, thiab cov chaw pej xeem.
