Properties
Raws li kev xyaum qhia, cov tsev ci ci ci tau zoo dua piv rau cov vaj tse pob zeb. Av nplaum, uas dhau los ua cov txheej txheem tsim nyog, ua kom sov thiab txias tsis zoo. Lub tsev nthuav av nplaum muaj cov khoom zoo sib xws vim nws cov qauv ntxeem tau. Tab sis yog tias koj yuav siv cov rwb thaiv tsev no ua cov thermal rwb thaiv tsev, ces koj yuav tsum paub txog nws cov thermal conductivity. Rau cov khoom no, nws nruab nrab yog 0.12 W / Km. Txawm li cas los xij, kojyuav tsum coj mus rau hauv tus account tias qhov loj ntawm cov granules yuav txawv.
Tab sis cov no tsis yog txhua tus yam ntxwv uas koj yuav tsum paub txog ua ntej pib ua haujlwm. Piv txwv li, nws yog ib qho tseem ceeb uas yuav tau xav txog qhov ceev. Thaum ua cov kev ntsuam xyuas compression, nws tau paub tias 13 feem pua ntawm cov ntim tau tawg. Qhov no tso cai rau ntxiv txheej compaction.
Ceev thiab hnyav
Cov av nplaum nthuav dav, qhov ntom ntom uas yuav txawv, muab faib ua ntau hom. Yog hais tias peb tham txog M-450 hom nrog ib feem ntawm 10-20 millimeters, ces qhov ceev ntawm cov khoom yog 440 kilograms ib cubic meter. Whereas lub hom M-500 muaj qhov ceev ntawm 465 kilograms ib cubic meter.
Tab sis qhov zoo ntawm cov av nplaum nthuav dav kuj nyob ntawm cov duab ntawm cov feem. Cov granules yuav tsum muaj qhov sib npaug, thiab qhov nruab nrab yuav tsum tau muab tshem tawm los ntawm qhov sib npaug.
Nws tseem ceeb heev kom paub tias qhov hnyav ntawm cov av nplaum nthuav dav yog dab tsi. Qhov taw qhia zoo tshaj plaws yog 0.95 grams ib cubic meter. Txawm hais tias qhov ntom ntom yuav nyob ntawm ntau yam, qhov loj ntawm cov nplej yuav tsum suav nrog. Piv txwv li, ib lub cubic meter ntawm cov khoom, feem ntawm uas yog 30 millimeters, yuav hnyav kwv yees li 340 kilograms.
siv thaj chaw
Thaum xaiv cov khoom siv hauv tsev piav qhia, tsis yog qhov hnyav ntawm cov av nplaum nthuav dav yog qhov tseem ceeb, tab sis kuj muaj lwm yam ntxwv. Txawm li cas los xij, ua ntej kev yuav khoom, koj yuav tsum txiav txim siab seb qhov rwb thaiv tsev thermal no puas haum rau thaj chaw tshwj xeeb. Thaum xub thawj siab ib muag, tej zaum yuav zoo li hais tias lub Scope yog tsis heev, txawm li cas los, granulesQhov sib txawv ntawm cov yam ntxwv ntawm kev txuag hluav taws xob zoo heev, uas tso cai rau kev siv cov rwb thaiv tsev no hauv kev npaj ntawm cov plag tsev, hauv qab nthab, nrog rau cov qab nthab. Nws yog tsim nyog sau cia tias thermal rwb thaiv tsev tsis yog qhov kawg ntawm cov khoom siv tau zoo.
