Cov tsev niaj hnub xav tau cov ntaub ntawv uas txuag hluav taws xob thiab nyob ruaj khov thiab rwb thaiv tsevcov vaj huam sib luag sandwichua tau raws li qhov kev thov no. Lawv muab cov khoom rwb thaiv tsev, cov qauv, thiab kev tsim qauv ua ke rau hauv ib lub tshuab. Cov neeg ua vaj tse siv lawv rau cov tsev rau khoom, cov chaw tsim khoom, thiab cov chav txias.
Cov vaj huam sib luag ua tau zoo nyob rau hauv ntau yam huab cua thiab tej yam kev mob. Lawv tsim cov qauv tsev uas ruaj khov thiab txuag hluav taws xob. Lawv cov thermal efficiency thiab kev nyab xeeb hluav taws ua rau lawv zoo tagnrho rau cov haujlwm niaj hnub.
Lub Luag Haujlwm ntawm Cov Vaj Huam Sib Luag Sandwich Insulated
Txhua lub vaj huam sib luag sandwich uas muaj rwb thaiv tsev muaj ob daim hlau nrog lub hauv paus rwb thaiv tsev. Cov qauv no txo qhov hloov pauv cua sov thiab muaj kev ruaj khov siab.
Cov vaj huam sib luag insulated sandwich ua haujlwm ntau lub luag haujlwm hauv kev tsim vaj tsev niaj hnub. Lawv txoj haujlwm tseem ceeb yog tswj qhov kub thiab txias hauv cov tsev. Lub hauv paus rwb thaiv tsev txwv tsis pub cua sov poob thaum lub caij ntuj no thiab cua sov nce thaum lub caij ntuj sov. Qhov no txo kev siv hluav taws xob rau kev ua kom sov thiab txias. Kev tshawb fawb qhia tau tias cov tsev siv cov vaj huam sib luag insulated tuaj yeem txuag tau 30% txog 50% ntawm lub zog piv rau cov phab ntsa ib txwm muaj.
Lawv kuj txo qhov kev sib kis suab nrov. Ntau lub Hoobkas thiab cov chaw ua haujlwm xav tau qhov chaw ua haujlwm ntsiag to. Lub vaj huam sib luag cov qauv ntom ntom thaiv suab zoo. Lub vaj huam sib luag polyurethane 50 hli tuaj yeem txo qhov suab nrov li ntawm 25 dB.
Lwm lub luag haujlwm tseem ceeb yog kev tiv thaiv. Cov hlau nto tiv taus cua, nag, thiab xeb. Nws tiv thaiv cov khoom siv rwb thaiv tsev thiab ua kom lub kaw lus ruaj khov. Cov txheej sab nraud muaj zog tso cai rau cov vaj huam sib luag los tuav cov khoom hnyav. Qhov no pab lawv kav ntev ntau xyoo yam tsis tas yuav saib xyuas ntau.
Hauv cov chav txias thiab chav huv si, cov vaj huam sib luag tswj tau qhov kub thiab txias tas li. Lawv tiv thaiv cov dej noo thiab cov kab mob loj hlob los ntawm lawv cov nplaim du thiab tsis muaj qhov. Cov pob qij txha ntawm cov vaj huam sib luag nruj nreem, uas ua rau huab cua sib khi zoo dua.
Cov kws kes duab vajtse siv cov vaj huam sib luag no los tsim cov tsev uas txuag hluav taws xob, tsis hnyav, thiab ruaj khov. Lub kaw lus no muaj kev rwb thaiv tsev, qauv, thiab kev zoo nkauj. Cov neeg ua vaj tse txuag lub sijhawm vim tias cov vaj huam sib luag tau tsim ua ntej nrog qhov loj me ruaj khov. Txhua daim tuaj yeem haum sai sai ntawm qhov chaw, txo cov nqi zog ua haujlwm.
Cov Yam Ntxwv Tseem Ceeb
Cov vaj huam sib luag sandwich insulated muaj ntau yam ntxwv tseem ceeb. Lawv cov thermal rwb thaiv tsev yog qhov tseem ceeb tshaj plaws. Lub hauv paus feem ntau siv polyurethane (PU), polyisocyanurate (PIR), lossis pob zeb wool. Txhua yam khoom muaj kev ua haujlwm thermal sib txawv.
Cov vaj huam sib luag PU muaj cov thermal conductivity ntawm li 0.022 W / m · K, uas txhais tau tias zoo heev rwb thaiv tsev. PIR cores muab kev tiv thaiv hluav taws kub dua nrog kev ua haujlwm zoo sib xws.
Cov vaj huam sib luag kuj muab lub zog kho tshuab siab. Cov tawv nqaij hlau sib koom cov khoom thauj nrog lub plawv, tsim cov qauv sib xyaw ruaj khov. Lub vaj huam sib luag PU tuab 100 hli uas muaj hlau tuaj yeem dais siab txog li 150 kPa. Lub zog no ua rau lawv haum rau cov ru tsev, phab ntsa, thiab chav txias.
Lwm yam tseem ceeb yog kev tiv thaiv hluav taws. PIR thiab cov pob zeb wool cores tuaj yeem ua tiav qib B1 lossis Chav Kawm A qhov ntsuas hluav taws. Lawv ncua qhov hluav taws kub thiab txo qhov tso pa tawm. Piv txwv li, lub vaj huam sib luag pob zeb wool 75 hli tuaj yeem tiv thaiv hluav taws tau ntau dua 60 feeb.
Lawv lub zog ruaj khov kuj zoo kawg nkaus. Cov ntawv hlau, feem ntau yog cov hlau galvanized lossis coated, tiv taus xeb thiab noo noo. Ntau lub tuam txhab tsim khoom siv polyester lossis PVDF coatings los txuas lub neej ntawm qhov chaw ntau tshaj 20 xyoo.
Tsis tas li ntawd xwb, cov vaj huam sib luag no muaj ntau yam zoo nkauj. Lawv muaj ntau yam xim, cov qauv, thiab cov tiav. Cov nto du, ribbed, lossis embossed tuaj yeem phim cov qauv tsim sib txawv.
Thaum kawg, kev yooj yim ntawm kev teeb tsa ntxiv tus nqi ntau dua. Cov vaj huam sib luag yog lub teeb yuag thiab yooj yim rau kev tuav. Cov neeg tsim kho siv cov khoom siv zais thiab cov kab sib koom ua ke los tsim cov kab huv si. Qhov no txo lub sijhawm tsim kho thiab ua kom tiav zoo nkauj.
Kev Ceeb Toom Txog Kev Tsim Khoom
Kev tsim cov vaj huam sib luag sandwich insulated xav tau kev tswj hwm nruj. Txhua theem cuam tshuam rau kev ua tau zoo thiab zoo. Cov chaw tsim khoom pib nrog cov ntawv hlau zoo. Cov hlau yuav tsum muaj txheej zinc kom zoo kom tiv thaiv kev xeb. Feem ntau qhov tuab yog li ntawm 0.4 hli txog 0.8 hli nyob ntawm tus qauv tsim.
Tom ntej no yog kev kho qhov chaw. Qhov chaw hlau yuav tsum huv thiab qhuav ua ntej pleev xim. Tej roj, hmoov av, lossis xeb yuav cuam tshuam rau kev nplaum. Ib txheej txheej zoo, xws li PVDF lossis polyester, ua rau muaj kev tiv taus huab cua ntau dua.
Lub hauv paus rwb thaiv tsev xav tau cov khoom siv kom raug. Rau PU thiab PIR, qhov sib piv tshuaj lom neeg thiab kev tswj qhov kub yog qhov tseem ceeb. Txawm tias qhov yuam kev me me tuaj yeem txo qhov ceev ntawm cov ua npuas ncauj lossis tsim cov qhov khoob. Cov vaj huam sib luag pob zeb xav tau kev taw qhia fiber thiab qhov ceev kom tswj tau qhov ua tau zoo hluav taws.
Thaum lub sijhawm tsim khoom tas mus li, cov khoom ua npuas ncauj lossis cov khoom siv tseem ceeb yuav txhaj rau ntawm cov ntawv hlau. Cov txheej txheem xav tau kev tswj hwm qhov siab thiab kev ceev kom raug. Kev lamination tsis sib xws tuaj yeem ua rau lub zog sib txuas ntawm cov tseem ceeb thiab daim tawv nqaij tsis muaj zog. Cov kab ntau lawm siv cov txheej txheem kub thiab siab tsis siv neeg kom ntseeg tau tias zoo sib xws.
Kev txiav thiab kaw ntug kuj tseem yuav tsum tau saib xyuas. Cov pob qij txha txiav txim siab qhov kub thiab txias. Qhov sib txawv me me yuav ua rau muaj dej noo thiab cua sov tawm. Cov chaw tsim khoom feem ntau siv cov kev sib txuas ntawm tus nplaig thiab qhov zawj lossis cov ntsia hlau zais kom txhim kho kev kaw.
Kev tshuaj xyuas zoo ua tiav cov txheej txheem. Cov vaj huam sib luag raug kuaj xyuas seb puas tuab, ceev, nplaum, lub zog khoov, thiab tus cwj pwm hluav taws. Cov ntaub ntawv ua kom cov khoom ua tau raws li cov qauv hauv tebchaws thiab thoob ntiaj teb.
Kev ntim khoom thiab kev thauj mus los kom zoo yuav ua rau cov vaj huam sib luag muaj kev nyab xeeb ua ntej kev teeb tsa. Kev cuam tshuam thaum lub sijhawm xa khoom tuaj yeem ua rau cov npoo lossis txheej puas tsuaj. Yog li ntawd, cov vaj huam sib luag raug teeb tsa tiaj tus thiab qhwv nrog zaj duab xis tiv thaiv.
Cov lus tawm tswv yim txog qhov project
Harbin Dong`an Tsev Ntawv Co., Ltdyog tus thawj coj tsim khoom ntawm cov vaj huam sib luag sandwich hauv Suav teb. Lub tuam txhab Dong`an muaj ntau qhov project tiag tiag ntawm cov vaj huam sib luag sandwich insulated. Cov haujlwm no qhia txog lub zog ntawm cov vaj huam sib luag sandwich insulated.
Hauv lub tsev rau khoom xa tuaj uas tau tsim tsa hauv tebchaws Malaysia, cov kws ua haujlwm tau siv 100 hli PIR vaj huam sib luag rau lub ru tsev thiab 75 hli rau phab ntsa. Lub tsev tau txuag hluav taws xob tau 45% piv rau cov phab ntsa thaiv rwb thaiv tsev ib txwm muaj. Qhov kub hauv tsev tseem ruaj khov hauv ± 2 °C txawm tias nyob hauv tshav ntuj ncaj qha.
Ib lub chaw cia khoom txias hauv Philippines siv 150 hli PU vaj huam sib luag rau cov chav khov. Qhov kub sab hauv tseem nyob ntawm -25 ° C nrog tsuas yog 3 ° C hloov pauv ib hnub. Kev siv hluav taws xob poob qis 30% tom qab hloov cov laug cam rwb thaiv tsev qub.
Nyob rau hauv Tebchaws Europe thiab Lavxias teb sab, cov vaj huam sib luag sandwich wool pob zeb nrov heev hauv cov chaw tsim khoom vim muaj kev nyab xeeb hluav taws. Lub chaw ua haujlwm 1,200 m² siv cov vaj huam sib luag pob zeb 80 hli ua tau raws li EN 13501 Class A cov qauv hluav taws. Kev tiv thaiv hluav taws kav ntev dua 90 feeb hauv kev sim.
Cov neeg ua vaj tse kuj siv cov vaj huam sib luag no rau cov tsev uas txuag hluav taws xob. Ib lub tsev me me uas muaj 50 hli PU vaj huam sib luag tuaj yeem ncav cuag qhov coefficient hloov pauv cua sov (U-value) ntawm 0.38 W/m²·K. Qib no phim ntau tus qauv tsev passive.
Cov vaj huam sib luag sandwich uas muaj cov rwb thaiv tsev sib xyaw ua ke cov rwb thaiv tsev, lub zog, thiab kev tsim qauv hauv ib qho system zoo. Lawv pab cov tsev niaj hnub txuag hluav taws xob thiab nyob ruaj khov. Lawv sawv cev rau txoj kev sib npaug ntawm kev ua haujlwm zoo, kev nyab xeeb, thiab kev tsim qauv niaj hnub rau yav tom ntej ntawm kev tsim kho. Thaum kev tsim kho ruaj khov loj hlob tuaj, cov vaj huam sib luag sandwich uas muaj cov rwb thaiv tsev yuav muaj nqis ntau dua.
