Sixelela indlela yokukhetha izinto zokufakelwa kobushushu, chonga ubukhulu obukhoyo kunye namandla kwaye uyincamathisele kwisiseko.
Isidingo sokufakwa kwezakhiwo ezingaphandle kwezakhiwo ezingaphantsi komhlaba ziphakama kwiimeko ezahlukeneyo. Umzekelo, xa bekucwangcisiwe ukulungiselela ukucwangciswa kwegumbi elingaphantsi, okanye elingaphantsi okanye ukukhusela isiseko kwi-rosty powder. Emva kwayo yonke loo nto, uninzi lwemihlaba kumgaqo ophakathi welizwe lethu lunodongwe kunye ne-loam. Isidlo sabo sihlala singunobangela wengcaciso nesiseko sesiseko. Umaleko wezinto eziphalazelayo uya kuphelisa okanye ukwenzela le nkqubo yeenkqubo ezingalunganga. Ukongeza, uya kukhonza njengendawo yokubonelela ngomonakalo ngexesha lokubuyela umva emhlabeni.
Ukukhetha kwezinto zokufakwa kobushushu
Uninzi lwazo, iipleyiti ze-polystyrene ekhutshiweyo (xPs), ezibandakanya iiseli ezivaliweyo ezivunyiweyo zisetyenziselwa ukufaka indawo engaphantsi komhlaba. Isixhobo sinengxaki yokuphumelela esezantsi - i-0.028-0.032 w / (m • c), ayisebenzi amanzi (ubuncinci bomsebenzi) kwaye, ngenxa yoko, inesingqala kakhulu. Yiyo racks, ayikho ngokuxhomekeka ekuboleni, azinzileyo phantsi komthwalo.
Ubomi benkonzo yeeplate ze-polystyrene ekhutshiweyo emhlabeni buyiminyaka engama-50. Kwimarike yethu, olu hlobo lokufakelwa kwe-thermal lunikelwa zii-penpeles, i-teknyanyayol, i-ireas.

Ubunzima kunye namandla okufakelwa kobushushu
Ubukhulu obungaphezulu kobunyulu bokufakwa kwe-thermal kwisiseko bugqitywa ngenxa yobalo ngokwendlela echazwe kwi-SP50.13330.2 "ukukhuselwa kwezakhiwo". Kwimimandla enemozulu eyahlukeneyo yemozulu, le paratho yento yokufakelwa iyahluka. Kumgaqo ophakathi waseRussia kwiindonga ze-XPs ezinamacala angama-50 mm. Kodwa iimbombo ezithintelwe kuqala kubo bonke, iingcali zincomela ukuba zikwazi ukwahlula izinto ezinkulu zobuninzi (60-100 mm).
I-volystyrene eyandisiweyo (i-XPS) ye-rssa
Ukuba nje iindonga ezithe nkqo kulindeleke ukuba zitshiswe, kwandula ke amandla anyuke kungafuneki kwi-prisantinting. Emva kwayo yonke loo nto, umthwalo kuphela ovela emhlabeni wokubuyela umva uyasebenza. Ke ngoko, amandla oxinzelelo olwenziweyo: 150-250 KPA. Imithwalo kwiipleyiti ze-XPS zibekwe phantsi kwesiseko se-slab okanye phantsi kwe "yedwa" yesiseko, kwisiseko, ngakumbi, yandisa iimfuno zamandla abo. Kule meko, iipleyiti zokufakwa kwe-irmal zikhethiweyo, amandla engcinezelo ye-250-400 kpa.
Kwiziphelo zeplate zeplate ye-polystyrene eyandisiweyo ye-polystyrene kukho ukutywinwa. Enkosi kuye, udibaniso lwezixhobo ezikufuphi lwenza inqaba, ethintela ukwenziwa kweebhlorho ezibandayo. Amalungu e-slab ethe chu enqwenelekayo ukuba i-lazinate ye-laminate iglue okanye i-mastic.
Ukubopha indawo yokuzahlula kwisiseko
Iiplate ze-polystyrene ye-polystyrene ilungisiwe kwindawo etywiniweyo yesiseko okanye iindonga zegumbi elingaphantsi, ngaphezulu komaleko wokudibana okanye ukungena kwamanzi. Ukuqinisa iipleyiti zisebenzisa iincwadana ezinemifanekiso ekhethekileyo okanye i-mastic, ezingafakwanga kwizinyithi zezinto eziphilayo (i-toluene, i-acetone, ipetroli, njl. Njl.). Kungenjalo, iglu iyakutshabalalisa umxokelelwane wepolystyrene.
Ukongeza kwiingoma zokuhlambela, iingcali zincoma ukusebenzisa iifayili zoomatshini, ezizezisi. Umqolo ongezantsi wezinto ezifakelweyo zixhomekeke kwi-SANDY-GRALL. Kodwa kungcono kwinqanaba lokusenisa isiseko sokubonelela oku kukhenyuzo oluncinci.
