Cov ntaub ntawv tshiab tau hloov pauv lub qhov rooj thiab qhov rais kev lag luam, muab kev ua tau zoo, kev zoo nkauj, thiab kev ruaj khov. Ib qho khoom siv zoo li no yog fiberglass, paub txog nws lub zog, durability, thiab tsis tshua muaj txij nkawm. Fiberglass qhov rooj thiab qhov rais tiv thaiv warping, rotting, thiab o, ua rau lawv zoo tagnrho rau ntau yam huab cua. Tsis tas li ntawd, fiberglass tuaj yeem tsim los ua kom zoo li cov ntoo, muab qhov zoo nkauj classic yam tsis muaj kev cuam tshuam.
Cov ntaub ntawv sib xyaw, uas sib txuas cov ntoo fibers thiab polymers, kuj tau txais koob meej. Cov ntaub ntawv no muab kev zoo nkauj ntawm ntoo nrog kev txhim kho kev tiv thaiv kom ya raws, kab, thiab lwj. Composite qhov rooj thiab qhov rais muab cov rwb thaiv tsev zoo heev, pab txhawb kev siv zog thiab kev nplij siab hauv tsev.
Lwm cov khoom siv tshiab yog uPVC (unplasticized polyvinyl chloride), uas muaj nuj nqis rau nws cov kav ntev, thermal efficiency, thiab tsis tshua muaj txij nkawm. uPVC qhov rooj thiab qhov rais tiv taus huab cua, corrosion, thiab fading, ua rau lawv haum rau siv mus ntev. Lawv kuj muaj cov khoom siv hluav taws xob zoo tshaj plaws, txo kev siv hluav taws xob thiab cov nqi.
Cov iav ntse, cov khoom siv niaj hnub, yog kev hloov pauv qhov rais thev naus laus zis. Cov iav no tuaj yeem hloov pauv nws qhov pom tseeb hauv cov lus teb rau cov teeb liab hluav taws xob, tso cai rau kev tswj hwm lub teeb thiab cua sov. Cov iav ntse txhim kho lub zog ua haujlwm los ntawm kev txo qhov xav tau ntawm cov teeb pom kev zoo thiab cov cua txias, ua rau muaj kev nyob ruaj khov thiab xis nyob.
Hauv kev xaus, lub qhov rooj thiab qhov rais kev lag luam tab tom muaj kev hloov pauv uas tau tsav los ntawm cov khoom siv tshiab. Fiberglass, cov ntaub ntawv sib xyaw, uPVC, thiab cov iav ntse muab kev ua tau zoo, kev zoo nkauj, thiab kev ruaj khov, ua rau cov tswv tsev niaj hnub xav tau. Cov kev nce qib no tau teeb tsa cov qauv tshiab hauv kev ua haujlwm ntev, kev siv hluav taws xob zoo, thiab kev tsim qauv yooj yim, ua rau lub tsev yooj yim dua, ua haujlwm tau zoo, thiab pom kev txaus siab.
