Insulated kav yuav tsum tau txais kev lees paub tshuaj xyuas thaum tuaj txog ntawm qhov chaw tsim kho, ua ntej kev teeb tsa. Txawm li cas los xij, vim muaj kev txwv ntawm - qhov chaw nyob, nws tsis muaj peev xwm ua kom tiav tag nrho cov kev xeem uas tau ua hauv chav kuaj. Yog li, qhov kev kuaj xyuas dab tsi tuaj yeem ua tau ntawm -site?
Ua ntej yog kev txheeb xyuas cov ntaub ntawv. Qhov no suav nrog cov khoom pov thawj ntawm kev ua raws cai, kev tshuaj xyuas lub Hoobkas, daim ntawv pov thawj zoo, thiab cov khoom siv tshwj xeeb. Reputable manufacturers test every batch for properties such as density, thermal conductivity, closed-cell content, and outer casing wall thickness before shipment; cov ntaub ntawv no yuav tsum tau muab nrog cov khoom. Cov ntawv cog lus tseem tuaj yeem suav nrog cov nqe lus uas hais txog qhov tsis sib xws ntawm - qhov chaw ua piv txwv rau kev sim ywj pheej.
Qhov thib ob yog kev kuaj pom. Saib xyuas cov txheej sab nrauv kom pom qhov tsis xws luag xws li khawb, tawg, dents, lossis npuas. Raws li tus qauv GB / T 29047, lub casing sab nrauv yuav tsum tsis muaj qhov tsis xws luag. Qhov xwm txheej ntawm lub kaus mom tsis muaj dej tsis txaus- kuaj xyuas seb lawv puas zoo li qub lossis tau raug tshem tawm - kuj tuaj yeem pom ncaj qha rau ntawm - qhov chaw. Cov txheej ua npuas ncauj ntawm cov yeeb nkab kawg yuav tsum tau kuaj xyuas qhov kev puas tsuaj, ya raws, lossis tsis muaj xim.
Tom ntej no yog qhov ntsuas qhov ntsuas. Siv ib daim kab xev ntsuas los yog caliper los ntsuas cov kab sab nraud, phab ntsa thickness, thiab qhov ntev ntawm cov yeeb nkab kawg (ntev ntev). Lub rwb thaiv tsev txheej thickness yuav tsum tau ntsuas ntawm plaub lub ntsiab lus nyob ib ncig ntawm cov yeeb nkab kawg (sab saum toj, hauv qab, sab laug, thiab sab xis) thiab nruab nrab. Kev kuaj xyuas ntawm cov phab ntsa sab nrauv yog qhov tsim nyog, vim tias qhov tuab tsis txaus cuam tshuam cov yeeb nkab lub zog compressive thiab muaj peev xwm tiv thaiv dej. Qhov tshwj xeeb ntev ntawm cov yeeb nkab kawg yuav tsum ua tau raws li cov qauv kev cai, feem ntau yog qhov tsawg kawg nkaus ntawm 150 mm.
While foam density and closed-cell content cannot be precisely measured on-site, a preliminary assessment can be made using simple methods. Nias lub npuas ntawm cov yeeb nkab kawg los ntawm txhais tes los ntsuas nws qhov ntom thiab xyuas seb muaj qhov muag muag lossis sponginess. Saib ntawm tus ntoo khaub lig- ntu ntawm cov npuas dej kom pom tias cov hlwb tsis sib xws thiab zoo, lossis yog tias muaj cov voids pom tseeb lossis loj, coarse cells. Txawm hais tias cov no yog cov kev ntsuam xyuas cov ntsiab lus, cov kws tshuaj ntsuam xyuas muaj peev xwm txheeb xyuas ntau yam teeb meem no.
Hauv -Kev tshuaj xyuas qhov chaw lees paub yog qhov chaw kuaj zaum kawg rau kev tswj xyuas kom zoo. Thaum cov kav dej raug faus, nws lig dhau los kho cov teeb meem. Txawm hais tias thaj tsam ntawm - qhov chaw soj ntsuam tsuas yog txwv, ua cov kev kuaj xyuas no kom huv si tuaj yeem lim tawm cov khoom uas muaj qhov tsis zoo.
