qhov rais loj
Qhov loj ntawm lub qhov rais feem ntau yog nyob ntawm qhov yuav tsum tau muaj ntawm chav tsev' lub teeb pom kev zoo thiab qhov cua, kev coj ua thiab kev tsim vaj tsev, thiab yuav tsum ua raws li tam sim no" Lub Tsev Modulus Coordination thiab Unified Standards&ua quot;. Rau cov qhov rais siv nyob rau hauv cov vaj tse dav dav, muaj cov atlases nyob txhua qhov chaw. Qhov siab thiab dav ntawm ntau lub qhov rais feem ntau yog nthuav nrog ib qho qauv ntawm 3M raws li qhov loj me ntawm qhov qhib. Thaum tsim nyog, tsuas yog xaiv hom thiab loj ncaj qha [5] .
Qhov rooj thiab qhov rais" peb natures"
Lub cev lub cev ntawm lub qhov rooj thiab qhov rais feem ntau suav nrog huab cua infiltration, rainwater to, cua tsis kam, thermal rwb thaiv tsev, suab rwb thaiv tsev, thiab teeb pom kev zoo. Ntawm lawv, peb yam khoom kawg raug xaiv thiab tswj raws li cov kev xav tau tshwj xeeb ntawm chav ua haujlwm; thawj peb lub zog yog peb yam tseem ceeb ntawm lub tsev qhov rooj thiab qhov rais, uas yog, yog li ntawd - hu ua" peb lub zog" ntawm qhov rooj thiab qhov rais. Raws li cov kev cai ntawm" Classification and Test Methods for Airtightness, Watertightness and Wind Pressure Resistance of Building Doors and Windows" (GBT7106 - 2008), lub tsev qhov rooj thiab qhov rais muaj cov kev faib tawm sib txawv raws li qhov sib txawv ntawm kev ua tau zoo [5].
Cua - nruj qhov ntsuas ntawm lub qhov rooj thiab qhov rais: Kev faib tawm ntawm huab cua - nruj ntawm lub qhov rooj thiab qhov rais yog raws li cov huab cua infiltration ntim q1 ib chav tsev qhib seam ntev thiab cov huab cua infiltration ntim ib cheeb tsam q2 thaum lub siab sib txawv yog 10Pa nyob rau hauv tus qauv tej yam kev mob . Qib 8 [5].
Watertightness Performance index ntawm lub qhov rooj thiab qhov rais: Kev faib tawm ntawm qhov dej tsis sib haum ntawm lub qhov rooj thiab qhov rais yog siv qhov sib txawv ntawm qhov sib txawv ntawm cov theem dhau los ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib cais, thiab faib cov qhov rooj thiab qhov rais ntawm lub tsev mus rau 6 qib [5 ].
Cua siab qhov ntsuas qhov ntsuas ntawm lub qhov rooj thiab qhov rais: Qhov kev faib tawm ntawm cov cua siab tsis kam ntawm lub qhov rooj thiab qhov rais yog nyob ntawm qhov ntsuas ntsuas qhov sib txawv ntawm P3 raws li qhov ntsuas ntsuas, thiab lub qhov rooj thiab qhov rais sab nraum lub tsev tau muab faib ua 9 qib [5].
Tsis tas li ntawd, lub tsev qhov rooj thiab qhov rais kuj tseem muaj cov qauv tsim nyog thiab cov ntsuas ntsuas sib xws hauv cov ntsiab lus ntawm huab cua - borne suab rwb thaiv tsev kev ua tau zoo, thermal rwb thaiv tsev kev ua tau zoo thiab teeb pom kev zoo. Yog li ntawd, nyob rau hauv kev xaiv ntawm lub qhov rooj thiab qhov rais, hom thiab qib ntawm lub qhov rooj thiab qhov rais yuav tsum tau txiav txim siab thiab xaiv raws li tej yam xws li kev nyab xeeb, lub tsev qhov siab, thiab chav tsev yuav tsum tau siv nyob rau hauv ntau lub cheeb tsam, thiab qhov yuav tsum tau ntawm cov kev qhia txog kev ua tau zoo yuav tsum. tau ntsib [5] .
Qhov rooj thiab qhov rais txuag hluav taws xob
Lub tsev qhov rooj thiab qhov rais yog qhov tsis muaj zog tshaj plaws ntawm lub tsev lub hnab ntawv nrog cov thermal ua haujlwm tsis muaj zog, thiab lawv lub zog siv nyiaj rau 40 % rau 50% ntawm tag nrho lub zog siv ntawm lub tsev ntawv lub hnab ntawv. Nyob rau tib lub sijhawm, lub qhov rooj thiab qhov rais kuj tseem muaj cua sov - tau txais cov khoom siv hauv lub tsev, uas tuaj yeem tau txais lub hnub ci hluav taws xob los ntawm kev xa cov hnub ci mus rau hauv chav tsev, yog li nws yog ib qho tseem ceeb uas cuam tshuam rau cov thermal ib puag ncig ntawm lub tsev thiab lub tsev txuag hluav taws xob. [5].
Txhawm rau kom ua tiav lub zog zoo - txuag cov txiaj ntsig rau lub qhov rooj thiab qhov rais, ntxiv rau kev txaus siab rau peb qhov kev ua yeeb yam yooj yim, cov xwm txheej hauv zos, cov kev xav tau, cov qauv tsim vaj tsev thiab lwm yam yuav tsum tau ua kom tiav, thiab cov kev cai ntawm lub teb chaws lub zog - txuag cov qauv tsim rau qhov ntsuas qhov rooj thiab qhov rais tsim yuav tsum tau ua.
