Cov ntaub thaiv cua sov fiberglass yog tsim los ua cov khoom siv rwb thaiv tsev rau cov kav dej kub thiab txias txij li -20 ° F txog 1000 ° F. Cov ntaub thaiv cua sov yeeb nkab yog ua los ntawm cov iav fiber ntau uas muaj cov khoom siv sib txuas ua ke uas muaj 3 ko taw ntev. Cov fiberglass yog qhwv nrog All-Service Jacketing dawb nrog lub hau kaw rau kev teeb tsa sai thiab ruaj ntseg. Txhua ntu 3 ko taw ntawm cov ntaub thaiv cua sov yeeb nkab lag luam muaj daim kab xev uas siv los txuas ob ntu ntawm cov ntaub thaiv cua sov yeeb nkab ua ke.
Cov Khoom Siv Rwb Thaiv Yeeb Nkab Fiberglass thiab Cov Khoom Siv Rwb Thaiv Yeeb Nkab Mineral Wool yog ob hom kev rwb thaiv yeeb nkab qhib. Txhawm rau kom cov lus tshaj tawm no tsis yog kev tshawb fawb thiab yooj yim to taub, cov khoom rwb thaiv yeeb nkab kaw tsis pub dej ntws los ntawm lawv thaum cov khoom rwb thaiv yeeb nkab qhib, feem ntau yog cov khoom rwb thaiv yeeb nkab fiberglass, cia dej hla nws cov fibers.
Kev Nqus Suab yooj yim heev rau kev tswj hwm. Feem ntau cov khoom siv rwb thaiv tsev thiab cov khoom siv rwb thaiv tsev ntawm lub rooj tsavxwm tau tshaj tawm cov coefficient nqus suab (NRC) ntawm lawv daim ntawv teev cov ntaub ntawv.
Qhov siab dua ntawm Sound Absorption Coefficient, qhov zoo dua rau cov acoustics hauv koj chav.
Kev tiv thaiv suab nrov yuav nyuaj dua rau qhov kev daws teeb meem kom raug rau koj qhov teeb meem. Yog tias peb saib nws hauv qhov kawg, cia peb xav txog phab ntsa pob zeb piv rau phab ntsa uas tsuas yog ua los ntawm cov fiberglass batt uas muaj qhov sib zog me me (tsis muaj drywall kiag li). Yog tias koj nyob hauv chav sib ze tom qab phab ntsa pob zeb koj yuav hnov koj tus neeg zej zog tham tsawg dua li yog tias tsuas muaj fiberglass batt ntawm koj thiab koj tus neeg zej zog. Hauv qhov piv txwv no, pob zeb yog cov khoom siv tiv thaiv suab nrov zoo dua li tsuas yog fiberglass batt rwb thaiv tsev. Txawm li cas los xij, yog tias koj nyob hauv chav sib tham, koj yuav hnov lub suab qis dua yog tias koj phab ntsa yog fiberglass batt piv rau phab ntsa pob zeb. Hauv qhov piv txwv no, fiberglass batt yog lub suab nqus tau zoo dua li phab ntsa pob zeb.
Feem ntau tso scrims yog hais txog 20 - 40% thinner dua li woven cov khoom ua los ntawm tib lub xov thiab nrog ib tug zoo sib xws kev tsim kho.
Ntau tus qauv European xav kom cov ntaub thaiv ru tsev tsawg kawg nkaus rau ob sab ntawm daim scrim. Cov scrims uas muab tso ua ke pab tsim cov khoom nyias dua yam tsis tas yuav lees txais cov nqi qis dua. Nws muaj peev xwm txuag tau ntau dua 20% ntawm cov khoom siv raw xws li PVC lossis PO.
Tsuas yog cov scrims tso cai rau kev tsim cov ntaub thaiv ru tsev peb txheej sib npaug (1.2 hli) nyias heev uas feem ntau siv hauv Central Europe. Cov ntaub tsis tuaj yeem siv rau cov ntaub thaiv ru tsev uas nyias dua 1.5 hli.
Cov qauv ntawm ib tug pw scrim yog tsis pom nyob rau hauv qhov kawg khoom dua li cov qauv ntawm woven cov ntaub ntawv. Qhov no ua rau ib tug smoother thiab ntau txawm nto ntawm qhov kawg khoom.
Lub du nto ntawm cov khoom kawg uas muaj cov scrims pw tso cai rau weld lossis nplaum cov khaubncaws sab nraud povtseg ntawm cov khoom kawg yooj yim dua thiab ruaj khov nrog txhua lwm yam.
Cov chaw du dua yuav tiv taus kev qias neeg ntev dua thiab nyob ntev dua.
Kev siv cov iav fiber scrim reinforced nonwovens ua rau lub tshuab ua haujlwm ceev dua rau kev tsim cov ru tsev bitu-men. Yog li ntawd, lub sijhawm thiab kev siv zog ntau hauv lub Hoobkas ua cov ru tsev bitumen tuaj yeem tiv thaiv tau.
Cov nqi kho tshuab ntawm cov ntawv ru tsev bitumen tau txhim kho zoo los ntawm cov scrims.
Cov ntaub ntawv uas feem ntau yuav dua yooj yim, xws li ntawv, ntawv ci lossis zaj duab xis los ntawm ntau hom yas, yuav raug tiv thaiv kom tsis txhob dua los ntawm kev laminating cov no nrog cov scrims uas tau tso.
Txawm hais tias cov khoom siv woven yuav raug muab los ntawm loomstate, ib daim ntaub pw yuav ib txwm raug impregnated. Vim li no peb muaj kev paub dav dav txog cov binder twg yuav zoo tshaj plaws rau ntau daim ntawv thov. Kev xaiv cov nplaum zoo yuav ua rau kev sib txuas ntawm daim ntaub pw nrog cov khoom kawg zoo heev.
Qhov tseeb tias cov warp sab saud thiab sab qis hauv cov scrims pw yuav ib txwm nyob rau tib sab ntawm cov xov weft lav tias cov xov warp yuav ib txwm nyob hauv qab kev ntxhov siab. Yog li ntawd, lub zog tensile hauv kev coj warp yuav raug nqus tam sim ntawd. Vim yog qhov no, cov scrims pw feem ntau qhia txog kev txo qis elongation. Thaum laminating ib tug scrim ntawm ob txheej ntawm zaj duab xis lossis lwm yam ntaub ntawv, tsawg dua cov nplaum yuav tsum tau thiab qhov cohesion ntawm lub laminate yuav raug txhim kho. Kev tsim cov scrims ib txwm xav tau ib tug thermal ziab txheej txheem. Qhov no ua rau preshrinking ntawm cov polyester thiab lwm yam thermoplastic yarns uas yuav txhim kho ntau tom qab kev kho mob ua los ntawm cov neeg siv khoom.
