Iiphaneli zegumbi lokubanda ze-PU kunye ne-PIR zilawula ulwakhiwo lwanamhlanje lokugcina izinto ezibandayo. Isixhobo ngasinye sineenzuzo ezicacileyo zokuthintela ubushushu, ukhuseleko kunye neendleko. Ukuqonda umahluko wazo kunceda abatyali-mali, abayili, kunye nabaqhubi ukuba bakhethe isisombululo esifanelekileyo sokusebenza ixesha elide.
Zithini iiphaneli zegumbi elibandayo le-PU?
Iiphaneli zegumbi elibandayo le-PU zisebenzisa i-polyurethane foam njengezinto zokukhusela ezisisiseko. I-PU foam inesakhiwo seeseli ezivaliweyo esinikezela ngokushisa okuphantsi kunye nokunamathela okuqinileyo kwiindawo zesinyithi. Ngenxa yezi mpawu, iiphaneli ze-PU ziye zaba lukhetho oluqhelekileyo lokugcina ukutya okubandayo, amagumbi abandayo, kunye namagumbi abandayo.
Ubushushu obugqwesileyo:Enye inzuzo enkulu yeephaneli ze-PU ikukuba zigqunywe kakuhle kubushushu. Ukuqhuba kobushushu okuqhelekileyo kususela kwi-0.022 ukuya kwi-0.024 W/m·K, okunceda ukugcina amaqondo obushushu angaphakathi azinzileyo kwaye kunciphisa ukusetyenziswa kwamandla okukhenkceza. Kwiiprojekthi ezinobukhulu obuncinci bodonga, iiphaneli ze-PU zivumela abayili ukuba bafikelele kwiinjongo zokukhusela ngaphandle kokwandisa ubungakanani besakhiwo.
Iiphaneli zePU zikwabonelela ngendlela efanelekileyo yeendleko. Izinto ezisetyenzisiweyo kunye neenkqubo zemveliso zihlala zivuthiwe, nto leyo egcina amaxabiso ekhuphisana. Kwiiprojekthi zokugcina izinto ezibandayo ezincinci neziphakathi, iiphaneli zePU zihlala zibonelela ngolungelelwano olungcono phakathi kokusebenza kunye nolawulo lohlahlo-lwabiwo mali.
Nangona kunjalo, iiphaneli ze-PU zibonisa imida ekusebenzeni komlilo. Ifoam ye-PU eqhelekileyo ikwicandelo le-B2 fire rating. Phantsi kwamaqondo obushushu aphezulu, i-PU inokuthambisa kwaye ikhuphe umsi. Nangona izongezo ezithintela ilangatye ziphucula ukhuseleko, iiphaneli ze-PU zisajongene nemingeni enzima yokuvunywa kwiiprojekthi ezineemfuno eziphezulu zokukhusela umlilo.
Zithini iiPIR Cold Room Panels?
Iiphaneli zegumbi elibandayo le-PIR zisebenzisa i-polyisocyanurate foam njengezinto eziphambili. I-PIR foam yenziwa nge-chemical reaction eguquliweyo edala isakhiwo seringi esizinzileyo ngakumbi. Esi sakhiwo siphucula kakhulu ukumelana nomlilo kunye nokuzinza kobushushu.
Ukusebenza kakuhle komlilo:Eyona nzuzo ibalulekileyo yeepaneli ze-PIR kukusebenza kakuhle komlilo. Ubushushu be-PIR buhlala bufikelela kwinqanaba lomlilo le-B1 kwaye bubonisa ukumelana okungcono nokusasazeka komlilo kunye nokuveliswa komsi. Kwimeko yomlilo, i-PIR yenza umaleko wokukhusela ocothisa ukudluliselwa kobushushu kunye nomonakalo wesakhiwo. Kwiiprojekthi zokugcina izinto ezibandayo kwiipaki zezothutho, kwizibonelelo zamayeza, okanye kwiindawo zasezidolophini, olu phawu lubonelela ngenzuzo enamandla yokhuseleko.
Iiphaneli ze-PIR zikwasebenza kakuhle kwi-insulation yobushushu. Ukuhanjiswa kwazo kobushushu kudla ngokuba phakathi kwe-0.021 ukuya kwi-0.023 W/m·K, okulingana okanye kuphucuke kancinci kwiiphaneli ze-PU. Kwimijikelo yokusebenza emide, lo mahluko unokuguqulela ekongeni amandla okulinganisekayo, ingakumbi kumagumbi efriji anobushushu obuphantsi.
Eyona ngxaki iphambili yeephaneli ze-PIR ibandakanya iindleko. Imveliso ifuna izinto eziluhlaza ezikumgangatho ophezulu kunye nolawulo oluqinileyo lwenkqubo, nto leyo enyusa amaxabiso eephaneli malunga ne-10% ukuya kwi-20% xa kuthelekiswa neephaneli ze-PU. Ukongeza, i-PIR foam ibonisa ukubuthathaka okuphezulu kancinci, ngoko ke ukuphathwa ngononophelo ngexesha lokufakwa kubalulekile.
Ukuthelekisa iiPaneli zePIR kunye nePU kwizicelo zokugcina izinto ezibandayo
Xa kuthelekiswa iiphaneli zegumbi lokubanda ze-PIR kunye ne-PU, ukusebenza kwe-insulation yodwa akuchazi ukhetho lokugqibela. Ukhuseleko lomlilo, ubungakanani beprojekthi, ubushushu bokusebenza, kunye neemfuno zomthetho zonke zidlala indima ebalulekileyo.
Kwindawo yokugcina ukutya ebandayo eqhelekileyo, kwiindawo zokugcina imveliso entsha, kunye nendawo yokugcina eqandisiweyo yexesha elifutshane, iiphaneli ze-PU zihlala zihlangabezana neemfuno zobugcisa ngexabiso eliphantsi. Ezi projekthi zihlala zisebenza kwiindawo zoshishino ezilawulwayo, apho imithetho yomlilo ihlala ilawuleka kwaye ukonga imali kubaluleke kakhulu.
Kwiigumbi ezibandayo zamayeza, iziko ezinkulu zothungelwano lwezixhobo ezibandayo, kunye nezibonelelo ezijolise ekuthumeleni ngaphandle, iiphaneli ze-PIR zibonelela ngeengenelo eziqinileyo zokuthobela imithetho. Imigangatho emininzi yamazwe ngamazwe kunye nabanikezeli beinshurensi bakhetha izixhobo ezinokumelana nomlilo okuphezulu, nto leyo enciphisa umngcipheko wokusebenza ixesha elide.
Ubushushu bokusebenza bukwachaphazela ukhetho. Kumagumbi efriji aphantsi kakhulu angaphantsi kwe-30°C, iiphaneli ze-PIR zigcina uzinzo lwesakhiwo ngcono kwixesha elide lenkonzo. Iiphaneli ze-PU zisasebenza kakuhle kodwa zisenokuphelelwa kukwaluphala kancinci kancinci phantsi kweemeko ezinzima.
Indlela yokukhetha phakathi kweePIR kunye neePU Cold Room Panels
Ukukhetha phakathi kweephaneli ze-PIR kunye ne-PU kufuna uvavanyo olucacileyo lwezinto eziza kuqala kwiprojekthi. Ukuba ubuthathaka bebhajethi kunye nembuyekezo ekhawulezileyo kutyalo-mali zikhokelela ekwenzeni izigqibo, iiphaneli ze-PU zibonelela ngokusebenza okuthembekileyo nokuqinisekisiweyo. Zilungele iiprojekthi zokugcina izinto ezincinci ukuya kweziphakathi ezibandayo ezineemfuno zokhuseleko lomlilo eziphakathi.
Ukuba ukhuseleko lomlilo, imvume yomthetho, kunye nolawulo lomngcipheko wexesha elide ziphezulu, iiphaneli ze-PIR ziba lukhetho olukhethwayo. Ixabiso lazo lokuqala eliphezulu lidla ngokunciphisa iingenelo zokuthobela imithetho, i-inshorensi kunye nokhuseleko kwixesha elizayo.
Abanini beprojekthi kufuneka baqwalasele imithetho yokwakha yasekuhlaleni, iimfuno zomshuwalense, kunye nexesha lokusebenza. Ukubonisana nabavelisi beepaneli kunye nabayili beendawo zokugcina izinto ezibandayo kuqinisekisa ukuba ukukhethwa kwezinto kuhambelana noyilo lwesakhiwo, umthamo wefriji, kunye nesicwangciso sokhuseleko.
Iiphaneli zegumbi lokubanda ze-PIR kunye ne-PU nganye inika ixabiso eliqinileyo xa isetyenziswa phantsi kweemeko ezifanelekileyo. Ngokulinganisa ukusebenza kwe-insulation, ukhuseleko lomlilo, iindleko, kunye neemfuno zomthetho, abaphuhlisi banokukhetha inkqubo yephaneli exhasa imisebenzi yokugcina izinto ezibandayo esebenzayo, ekhuselekileyo, nehlala ixesha elide.
