hnub ci teeb meem racking: EPDM thiab asphalt
Thaum npaj rau nruab hnub ci nruab hnub ci kev lag luam rau tsev lag luam lossis tsev, nws yog qhov tseem ceeb kom ntseeg tau tias txhua lub hauv paus ntawm lub hnub ci tsim khoom kom sib haum nrog lub ru tsev. Muaj ntau qhov teeb meem uas tuaj yeem cog qoob loo xws li qhov tseeb tias kev lag luam lub ru tsev tsis tuaj yeem ua tiav lub hnub ci hnyav thiab cov nplais pob zeb, cov khoom siv yas ntawm qee lub tshuab tsis tas li hluav taws kub, lossis cov vov tsev ua rau lub tsev ntoo coj tau qee yam teeb meem. Ib qhov tshwj xeeb tseem ceeb, thiab paub me me, qhov teeb meem yog tias EPDM cov tshuaj tsis haum nrog asphalt shinglescan ua rau muaj kev puas tsuaj ntawm lub ru tsev thiab lub ru tsev ua ntej.
Qhov teeb meem nrog EPDM
EPDM (ethylene propylene diene monomer) yog cov roj hmab hluavtaws ua haujlwm nrov thoob plaws kev lag luam vim tias nws tus nqi qis, siv tau ntev thiab ua haujlwm pwm. Tus lej zoo ntawm lub vov tsev txuas rau lub hnub ci racking kev lag luam siv EPDM gaskets los tsim cov foob dej ntim ncig ntawm lub vov tsev nkag mus. Thaum cov gaskets no ib txwm sib cais los ntawm lub ru tsev thaiv nrog lub teeb nyem hlau, muaj qee lub ru tsev txuas tshiab nkag mus hauv lub khw uas tsis siv lub teeb nrawm no txhawm rau kom muaj kev txuag nqi thiab txhim kho yooj yim dua. Txawm li cas los xij, qhov no yog qhov teeb meem vim tias EPDM tsis sib xws nrog bitumen, lossis roj av, cov khoom lag luam.
Asphalt shingles yog cov ntaub ntawv ua tiav ntawm cov roj av. Vim tias lawv cov nqi them nqi qis, yooj yim ntawm kev txhim kho thiab muaj nyob rau ntau lub kaum xim, xim pob zeb rau asphalt yog qhov kev xaiv nrov tshaj plaws rau cov vov tsev nyob thiab ntau lub tsev lag luam. Hmoov tsis zoo, kev sib cuag ntawm asphalt shingles thiab EPDM ua rau muaj tshuaj lom neeg cov tshuaj lom neeg uas muaj EPDM gasket los ua lub ntsej muag thiab noj rau hauv cov txee. Qhov no yog becausethe roj hmab tivthaiv ntawm EPDM degradeswhen muaj kev sib cuag nrog cov khoom me ntsis, qee yam ntawm kev sib cuam tshuam ntawm cov roj hmab sib cuam tshuam ntawm cov roj hmab nrog asphalthave paub tseeb. Raws li qhov tshwm sim, EPDM gaskets yuav tsum tsis txhob muaj kev sib cuag nrog asphalt shingles.
Txoj haujlwm daws teeb meem
Cov roj hmab Silicone yog qhov hloov pauv tau zoo rau EPDM roj hmab. Ithas cov khoom muaj zog uas ua rau nws zoo tshaj plaws rau kev siv sab nraum zoov, thiab cov txheej txheej silicone feem ntau siv rau saum ru tsev kom muab ib txheej txheej tiv thaiv uas pab ua kom ntev lub neej ntawm lub ru tsev. Silicone roj hmab yog sib xws nrog cov pob zeb ua tiav, TPO, PVC, EPDM vov vov thiab, ntawm chav kawm, kev tiv thaiv asphalt. Kev xaiv siv lub hnub ci tso tawm cov khoom lag luam uas siv cov silicone gaskets hla EPDM gaskets yog qhov kev xaiv zoo tshaj plaws, tshwj xeeb tshaj yog thaum saib ntsia lub nruab PV system ntawm lub ru tsev nrog asphalt shingles.
Hauv cov ntsiab lus, thaum nws tseem ceeb heev uas cov neeg tsim qauv, cov kws tsim qauv thiab cov kws tsim ua haujlwm sib zog txuag nyiaj thaum ua haujlwm ntawm lub ru tsev hnub ci tej yaam num, lawv yuav tsum ua li ntawd tsis cuam tshuam qhov ncaj ncees ntawm lub ru tsev. Nkag siab qhov tsis sib xws ntawm EPDM gaskets thiab asphalt shingle ru tsev npog tuaj yeem yog qhov sib txawv ntawm lub ru tsev ntev ntev tseem ceeb thiab lub ru tsev ua haujlwm tau txais txiaj ntsig thiab muaj txiaj ntsig zoo.
