Izakhiwo zanamhlanje zifuna izinto ezidibanisa ukhuseleko, amandla, ubushushu, kunye noboya belityeiiphaneli zesandwichlukhetho olufanelekileyo. Inika ukumelana okuhle nomlilo kunye nokuthintela isandi. Nangona kunjalo, iiphaneli zoboya belitye zemveli zijongene nobuthathaka obuninzi, njengokufunxwa kwamanzi kunye nokuqina okuncinci komphetho. Ukusombulula ezi ngxaki, kuye kwavela iphaneli entsha yesandwich yoboya belitye.
Iingenelo
Uboya belityeiiphaneli zesandwichkudala zixatyiswa ngenxa yeempawu zazo eziqinileyo zokumelana nomlilo kunye ne-acoustic. Zenziwe ngelitye le-basalt elinyibilikiswe kubushushu obungaphezulu kwe-1,450°C, uboya belitye bunomongo ongatshiyo onomlinganiselo womlilo weKlasi A1. Oku kuyenza ilungele iindonga kunye nophahla olumelana nomlilo kwizakhiwo zoshishino. Kwiimvavanyo zomlilo, iphaneli yoboya belitye eyi-100 mm inokumelana nomlilo ngokuthe ngqo kangangeeyure ezingaphezu kwe-2 ngaphandle kokuphazamiseka kwesakhiwo.
Enye inzuzo enkulu kukufunxwa kwesandi. Ulwakhiwo lwe-fiber yoboya belitye lunciphisa amanqanaba engxolo ngokufanelekileyo. Iphaneli enobukhulu obuyi-50 mm inokunciphisa ukudluliselwa kwesandi ngama-25–30 decibels, nto leyo eyenza ukuba ifaneleke kwiindawo zokusebenzela zemveliso okanye kwizikhululo zamandla.
Ubushushu obuphantsi bunokuthenjwa. Nangona bungasebenzanga kakuhle njenge-PU foam, iiphaneli zoboya belitye zigcina amaqondo obushushu azinzileyo ngaphakathi. Iphaneli ye-100 mm inika ukuhanjiswa kobushushu obumalunga ne-0.042 W/m·K, okwaneleyo ukunciphisa ukusetyenziswa kwamandla kwiindawo ezininzi zemozulu.
Iiphaneli zoboya belitye nazo zinokumelana okunamandla nokucinezelwa. Ubuninzi obuphakathi yi-100–150 kg/m³, nto leyo ebenza babe nozinzo oluphezulu kwisakhiwo. Zimelana kakuhle nemithwalo yomoya kunye nefuthe loomatshini.
Ukongeza, zinobuhlobo nokusingqongileyo. Izinto ezisetyenziswayo, i-basalt, zininzi kwaye zinokuphinda zisetyenziswe. Iifektri zingaphinda zisebenzise inkunkuma yoboya belitye ngexesha lokuveliswa, nto leyo enciphisa impembelelo yokulahlwa kwenkunkuma.
Iingxaki
Nangona zininzi izinto ezinamandla, iiphaneli zoboya belitye zinezinye izinto ezithintela ukusebenza kwazo. Eyona ngxaki ixhaphakileyo kukufunxwa kwamanzi. Iifayibha zoboya belitye zifunxa lula umswakama ovela emoyeni, nto leyo enyusa ubunzima kwaye inciphise ixabiso lobushushu. Kwiindawo ezifumileyo, umbane ohambayo unganyuka ukusuka kwi-0.042 ukuya kwi-0.060 W/m·K, nto leyo ebangela ukulahleka kwamandla ukuya kuthi ga kwi-30%.
Ukufunxwa kwamanzi kukwakhokelela ekuboleni kwemiphezulu yesinyithi ukuba ukufuma kwenzeka kufutshane nemiphetho. Ekuhambeni kwexesha, oku kunokunciphisa ubomi benkonzo yephaneli.
Enye ingxaki kukubuthathaka komphetho. Ingaphakathi loboya belitye alinamatheli ngokuqinileyo nezikhumba zentsimbi emacaleni. Ngexesha lokuthuthwa okanye ukufakwa, imiphetho inokuqhekeka okanye iqhekeke. Oku akuchaphazeli nje kuphela inkangeleko kodwa kunciphisa ukuqina komoya kunye namandla.
Ukuvala lolunye ubuthathaka. Ngaphandle konyango olufanelekileyo, imiphetho yeepaneli ivumela ukufuma kunye nokuvuza komoya. Oku kunokubangela ukulahleka kobushushu okanye ukukhula kwesikhunta.
Ukongeza, iiphaneli zoboya belitye zinobunzima obungaphezulu kunezinye iintlobo. Iphaneli yoboya belitye enobukhulu obuyi-100 mm inobunzima obumalunga ne-17–20 kg/m², ngelixa iphaneli ye-PU enobukhulu obufanayo inobunzima obuyi-12–14 kg/m² kuphela. Iiphaneli ezinzima zonyusa umthwalo kwizakhelo zokwakha kwaye zonyusa iindleko zokufakela.
Okokugqibela, inkqubo yemveliso ifuna ukusika nokuhlanganisa ngokuchanekileyo. Ukudibana okungekho ngqiqweni phakathi kwamaphepha entsimbi kunye nombindi kukhokelela ekuqhekekeni phantsi kokungcangcazela okanye uxinzelelo.
Ezi ngxaki zenza kube nzima kwiiphaneli zoboya belitye ukuhlangabezana neemfuno zanamhlanje zokonga amandla kunye nokumelana nokufuma, ingakumbi kumagumbi acocekileyo, amagumbi abandayo, okanye kwizakhiwo ezifumileyo ezikunxweme.
Uhlobo olutsha lweRock Wool Sandwich Panel
Iphaneli yesandwich yoboya belitye enomphetho we-PU yenzelwe ukudibanisa ukumelana nomlilo koboya belitye kunye namandla okutywina e-polyurethane. Kolu yilo, zombini imiphetho emide yephaneli izaliswe yi-PU foam, ngelixa umbindi ophakathi uhlala uboya belitye.
Olu lwakhiwo lwe-hybrid lusombulula ubuthathaka obuphambili beepaneli zoboya belitye zemveli. Imiphetho ye-PU yenza isivalo esiqinileyo, esivala amanzi kunye nokungena komoya. Uvavanyo lubonisa ukuba iipaneli ezinemiphetho ye-PU zinomoya ophantsi ngama-60% xa kuthelekiswa neepaneli zoboya belitye eziqhelekileyo. Oku kuphucula ukusebenza kakuhle kokugquma nakwiindawo ezinomswakama ophezulu.
Ukubophana phakathi komphetho we-PU kunye nepleyiti yentsimbi nako kwandisa amandla omphetho. Iiphaneli ziyamelana ngcono nokuchaphazeleka ngexesha lokuphathwa nokufakelwa. Umzekelo, kuvavanyo lwasefektri, ukuhla kwemitha e-1 akubangeli monakalo kumphetho kwiiphaneli zomphetho we-PU, ngelixa iiphaneli zoboya belitye eziqhelekileyo zibonisa imifantu ebonakalayo.
Umphetho we-PU ukwaphucula ukungabi namoya kwenkqubo yephaneli. Umphetho onegwebu uhambelana kakuhle neephaneli ezikufutshane, nto leyo enciphisa ukuvuza kobushushu. Oku kuvumela ukusebenza ngcono kwiindawo zokugcina izinto ezibandayo, kwiindawo zokusebenzela ezicocekileyo, nakwizakhiwo zeeofisi.
Enye inzuzo kukusebenza kakuhle kokufakela. Imiphetho ye-PU isebenza njengeendawo zokuvala zendalo, nto leyo enciphisa isidingo se-silicone okanye imicu yerabha. Abafaki banokufaka iiphaneli ngokukhawuleza, oko konga iindleko zomsebenzi nge-10–15%.
Ngokudibanisa amandla ezinto zombini, iphaneli yesandwich ye-PU edge rock wool ifikelela kumandla aphezulu okumelana nomlilo, ukhuseleko olungcono lokufuma, kunye nokuqina okuphuculweyo—konke kulwakhiwo olunye.
Iimpawu zobugcisa

Ukusebenza okungangeni manzi. Imiphetho ye-PU inesantya esivaliweyo seseli esingaphezulu kwama-95%. Olu lwakhiwo luvimba ukungena komswakama ngokufanelekileyo. Emva kokuntywiliselwa emanzini iiyure ezingama-24, iiphaneli zomphetho we-PU zifunxe ngaphantsi kwe-1% yobunzima bazo, ngelixa iiphaneli zoboya belitye eziqhelekileyo zifunxe ukuya kuthi ga kwi-6%.
Amandla olwakhiwo. Amandla okubopha phakathi kwezikhumba zentsimbi kunye nombindi ayanda ukusuka kwi-0.09 MPa ukuya kwi-0.13 MPa ngoyilo lomphetho we-PU. Iiphaneli ziyamelana nokugoba kunye nokucinezelwa ngcono, okuqinisekisa ukusebenza okuzinzileyo kwizakhiwo ezinkulu.
Ukuqina kunye nenkangeleko. Umphetho we-PU ubonelela ngenkangeleko egudileyo necocekileyo kwiindawo zokudibanisa iiphaneli, ukuthintela ukuqokelelana kothuli kunye nokugqwala. Oku kubaluleke kakhulu kwiifektri zokutya nakwiindawo zokucoca.
Izicelo kunye neendlela zeMarike
Iipaneli zesandwich ze-PU edge rock wool ziye zathandwa kakhulu kwiiprojekthi ezininzi zokwakha zanamhlanje. Ukumelana kwazo nomlilo kunye nokukhuselwa kokufuma kuzenza zifaneleke kwiifektri, kwiindawo zokugcina impahla, nakwizakhiwo zikawonke-wonke.
Kwiindawo ezinobungozi bomlilo ezifana nezityalo zoshishino kunye neendawo zokugcina izinto, iiphaneli zoboya belitye ziye zaba sisiqinisekiso esibalulekileyo sokhuseleko lomlilo. Iiphaneli zibonelela ngemizuzu eli-120 yokhuseleko lomlilo kunye nokufuma kwangaphakathi okuzinzileyo, okunciphisa izinga leziphene kwiindawo ezinobuthathaka nge-8%.
Amagumbi abandayo kunye neendawo zokugcina ukutya nazo ziyazuza kolu buchwepheshe. Imiphetho ye-PU iqinisekisa ukuvalwa okuqinileyo kwaye inciphisa ukuguquguquka kobushushu. Ukuvela kweepaneli zesandwich ze-PU rock wool kubonelele ngeendlela ezintsha zoyilo kunye nokwakhiwa kwendawo yokugcina ebandayo. Ngaphandle kokunciphisa iipropati zokukhusela zomzimba wendawo yokugcina ebandayo, ukusebenza kokhuseleko kwendawo yokugcina ebandayo kuphucuka kakhulu.
Kumagumbi okucoca nasezibhedlele, ucoceko lubalulekile. Iiphaneli ze-PU edge zithintela uthuli kunye neebhaktheriya ukuba zingangeni ngezithuba. Imiphetho egudileyo ikwanceda ukucoca kube lula kwaye kukhawuleze.
Njengoko imigangatho yokwakha yehlabathi isiya iqina, abaphuhlisi abaninzi bakhetha izinto ezixutyiweyo ezifana neephaneli zoboya belitye ezikumphetho we-PU. Le ndlela ixhasa iziqinisekiso zezakhiwo eziluhlaza kunye neenjongo zokonga amandla. Abavelisi abaninzi ngoku banikezela ngeephaneli ezinobukhulu obahlukeneyo (50–150 mm) kunye nemibala ukuhlangabezana neemfuno zokwakha.
Iphaneli yesandwich ye-PU edge rock wool isombulula le micimbi ngempumelelo. Ngokongeza imiphetho ye-polyurethane, iyomeleza ukutywinwa, iphucula ukugquma, kwaye yandisa ubomi. Njengoko imfuno yezinto zokwakha ezisemgangathweni ophezulu ikhula, iiphaneli ze-PU edge rock wool ziya kudlala indima ebalulekileyo kwisizukulwana esilandelayo sokwakha okukhuselekileyo, okusebenzayo, nokuzinzileyo.
