Izakhiwo zanamhlanje zifuna izinto ezigcina umbane kwaye zihlale ziqinile kwaye zigqunywe ngobushushuiiphaneli zesandwichbayahlangabezana nale mfuno. Badibanisa ubushushu, ulwakhiwo, kunye noyilo kwinkqubo enye. Abakhi bawasebenzisa kwiindawo zokugcina impahla, iifektri, kunye namagumbi abandayo.
Iiphaneli zisebenza kakuhle kwiimeko ezahlukeneyo zemozulu. Zenza ii-envelopes zokwakha ezizinzileyo nezisebenzisa amandla amaninzi. Ukusebenza kwazo kakuhle kobushushu kunye nokhuseleko lomlilo kuzenza zilungele iiprojekthi zanamhlanje.
Indima yeePaneli zeSandwich ezifakwe i-Insulation
Iphaneli nganye yesandwich egqunyiweyo inamashiti amabini esinyithi anesiseko sokukhusela. Esi sakhiwo sinciphisa ukudluliselwa kobushushu kwaye sinikezela ngokuqina okuphezulu.
Iipaneli zesandwich ezifakwe i-insulation zisebenza imisebenzi emininzi kuyilo lwanamhlanje. Umsebenzi wazo ophambili kukulawula ubushushu ngaphakathi kwezakhiwo. I-insulation core ithintela ukulahleka kobushushu ngexesha lasebusika kunye nokwanda kobushushu ehlotyeni. Oku kunciphisa ukusetyenziswa kwamandla ekufudumaleni nasekupholiseni. Izifundo zibonisa ukuba izakhiwo ezisebenzisa iipaneli ezifakwe i-insulation zingonga i-30% ukuya kwi-50% yamandla xa kuthelekiswa neendonga eziqhelekileyo.
Zikwanciphisa ukuhanjiswa kwengxolo. Iifektri ezininzi kunye neeworkshop zifuna iimeko zokusebenza ezizolileyo. Ulwakhiwo oluxineneyo lwephaneli luvimba isandi ngokufanelekileyo. Iphaneli ye-polyurethane engama-50 mm inokunciphisa ingxolo malunga ne-25 dB.
Enye indima ebalulekileyo kukukhusela. Umphezulu wesinyithi uyamelana nomoya, imvula, kunye nokugqwala. Ukhusela izinto zokukhusela kwaye ugcina inkqubo izinzile. Umaleko wangaphandle oqinileyo uvumela iiphaneli ukuba zithwale imithwalo enzima. Oku kuzinceda zihlale amashumi eminyaka ngaphandle kokulungiswa kakhulu.
Kwiindawo zokugcina izinto ezibandayo kunye namagumbi acocekileyo, iiphaneli zigcina ubushushu obufanayo kunye nococeko. Zithintela ukufuma kunye nokukhula kweebhaktheriya ngokusebenzisa iindawo zazo ezigudileyo, ezingenazimbobo. Amalungu phakathi kweephaneli aqinile, nto leyo ephucula ukuvaleka komoya.
Abayili bezakhiwo basebenzisa ezi paneli ukwenza izakhiwo ezisebenzisa amandla aphantsi, ezikhaphukhaphu, nezihlala ixesha elide. Le nkqubo idibanisa ubushushu, ulwakhiwo, kunye nobuhle. Abakhi bonga ixesha kuba iipaneli ziza sele zenziwe ngobungakanani obungaguqukiyo. Iqhekeza ngalinye linokungena ngokukhawuleza kwindawo, nto leyo enciphisa iindleko zomsebenzi.
Iimpawu eziphambili
Iipaneli zesandwich ezifakwe i-insulation zineempawu ezininzi eziphawulekayo. I-thermal insulation yazo imele ibe yeyona nto ibalulekileyo. I-core idla ngokusebenzisa i-polyurethane (PU), i-polyisocyanurate (PIR), okanye uboya belitye. Isixhobo ngasinye sisebenza ngendlela eyahlukileyo kwi-thermal.
Iiphaneli ze-PU zinombane ohamba ngobushushu omalunga ne-0.022 W/m·K, nto leyo ethetha ukuba i-insulation ingcono kakhulu. Ii-PIR cores zibonelela ngokumelana nomlilo okuphezulu kunye nokusebenza kwamandla okufanayo.
Iiphaneli zikwabonelela ngamandla aphezulu oomatshini. Izikhumba zentsimbi zabelana ngemithwalo nombindi, zenze isakhiwo esizinzileyo nesidibeneyo. Iphaneli ye-PU enobukhulu bentsimbi eyi-100 mm inokuthwala uxinzelelo olufikelela kwi-150 kPa. La mandla ayenza ifaneleke eluphahleni, eludongeni, nakwiindawo ezibandayo ezibiyelweyo.
Olunye uphawu oluphambili kukumelana nomlilo. Ii-PIR kunye nee-rock wool cores zinokufikelela kuvavanyo lomlilo lweClass B1 okanye lweClass A. Ziyalibazisa ukusasazeka komlilo kwaye zinciphise ukukhutshwa komsi. Umzekelo, iphaneli yoboya belitye engama-75 mm inokumelana nomlilo ngaphezu kwemizuzu engama-60.
Ukuqina kwazo kuyamangalisa ngokulinganayo. Amashiti esinyithi, adla ngokuba yintsimbi egqunyiweyo okanye egqunyiweyo, ayamelana nokugqwala nokufuma. Abavelisi abaninzi basebenzisa ii-polyester okanye ii-PVDF coatings ukwandisa ubomi bomphezulu obungaphezulu kweminyaka engama-20.
Ukongeza, ezi paneli zibonelela ngobuchule obuhlukeneyo. Ziza ngemibala eyahlukeneyo, iiprofayili, kunye nokugqitywa. Imiphezulu egudileyo, enemiqolo, okanye enemibala inokuhambelana noyilo olukhethiweyo.
Okokugqibela, ukulula kokufakela kongeza ixabiso elingakumbi. Iiphaneli zilula kwaye kulula ukuziphatha. Abakhi basebenzisa izibophelelo ezifihlakeleyo kunye neenkqubo zokudibanisa ukwenza imigca ecocekileyo. Oku kunciphisa ixesha lokwakha kwaye kuqinisekisa ukugqitywa kakuhle.
Ingqwalasela yeMveliso
Ukuveliswa kweepaneli zesandwich ezigqunyiweyo kufuna ulawulo olungqongqo. Inqanaba ngalinye lichaphazela ukusebenza kunye nomgangatho. Abavelisi baqala ngeeshiti zesinyithi ezikumgangatho ophezulu. Intsimbi kufuneka ibe ne-zinc coating efanelekileyo ukuthintela ukugqwala. Ubukhulu buhlala buqala kwi-0.4 mm ukuya kwi-0.8 mm kuxhomekeke kuyilo.
Okulandelayo kuza unyango lomphezulu. Umphezulu wentsimbi kufuneka uhlale ucocekile kwaye womile ngaphambi kokuba ugqunywe. Nayiphi na ioyile, uthuli, okanye umhlwa unokuchaphazela ukunamathela. Ugqunywe olusemgangathweni ophezulu, olufana nePVDF okanye ipolyester, lunyusa ukumelana nemozulu.
Isiseko sokwambathisa sidinga ukwakheka kwezinto ezichanekileyo. Kwi-PU kunye ne-PIR, umlinganiselo weekhemikhali kunye nolawulo lobushushu zibalulekile. Nokuba yimpazamo encinci inokunciphisa uxinano lwefoam okanye idale izithuba. Iiphaneli zoboya belitye zifuna ukujongwa kakuhle kwefayibha kunye noxinano ukuze kugcinwe ukusebenza okungenakutsha.
Ngexesha lokuveliswa okuqhubekayo, igwebu okanye izinto eziphambili zingena phakathi kwamaphepha esinyithi. Le nkqubo ifuna uxinzelelo oluchanekileyo kunye nolawulo lwesantya. Ukungalingani kwe-lamination kunokwenza buthathaka unxibelelwano phakathi kolusu nolusu. Imigca yemveliso ephucukileyo isebenzisa iinkqubo zobushushu ezizenzekelayo kunye noxinzelelo ukuqinisekisa umgangatho ofanayo.
Ukutywina okusikiweyo nokusemacaleni nako kufuna ukunyanyekelwa. Amalungu amisela ukuqina kobushushu nomoya. Isithuba esincinci sinokubangela ukufuma kunye nokuvuza kobushushu. Abavelisi badla ngokusebenzisa uqhagamshelo lolwimi kunye nomngxuma okanye izikrufu ezifihliweyo ukuphucula ukutywina.
Ukuhlolwa komgangatho kugqiba inkqubo. Iiphaneli zivavanyelwa ukutyeba, uxinano, ukunamathela, amandla okugoba, kunye nokuziphatha komlilo. Idatha iqinisekisa ukuba imveliso iyahlangabezana nemigangatho yesizwe neyehlabathi.
Ukupakishwa kakuhle kunye nokuthuthwa kakuhle kugcina iiphaneli zikhuselekile ngaphambi kokufakwa. Impembelelo yoomatshini ngexesha lokuhanjiswa inokonakalisa imiphetho okanye uqweqwe. Ngenxa yoko, iiphaneli zibekwe ngokuthe tyaba kwaye zisongelwe ngefilimu yokukhusela.
Ingxelo yeprojekthi
IHarbin Dong`an Building Sheets Co.,Ltdngumvelisi ophambili wepaneli yesandwich eTshayina. Inkampani yaseDong`an ineeprojekthi ezininzi zokwenyani zeepaneli zesandwich ezigqunyiweyo. Ezi projekthi zibonisa amandla eepaneli zesandwich ezigqunyiweyo.
Kwindawo yokugcina izinto eyakhiwe eMalaysia, iinjineli zisebenzise iiphaneli ze-PIR eziyi-100 mm eluphahleni kunye ne-75 mm eludongeni. Isakhiwo sizuze ukonga amandla nge-45% xa kuthelekiswa neendonga zebhloko zemveli ezigqunyiweyo. Ubushushu bangaphakathi buhlale buzinzile ngaphakathi kwe-±2 °C nokuba kuselangeni elithe ngqo.
Isityalo sokugcina izinto ezibandayo ePhilippines sisebenzise iiphaneli ze-PU eziyi-150 mm kwiindawo zokukhenkceza. Ubushushu bangaphakathi buhlale bukwi-−25 °C kwaye bekuguquguquka kwe-3 °C kuphela ngosuku. Ukusetyenziswa kwamandla kwehle nge-30% emva kokutshintsha iibhodi zokukhusela ezindala.
EYurophu naseRashiya, iiphaneli zesandwich zoboya belitye zithandwa kakhulu kwiifektri ngenxa yokhuseleko lomlilo. Indawo yokusebenzela eyi-1,200 m² esebenzisa iiphaneli zoboya belitye ezingama-80 mm ihlangabezane nemigangatho yomlilo ye-EN 13501 Class A. Ukumelana nomlilo kuthathe imizuzu engaphezu kwama-90 kwiimvavanyo.
Abakhi bezindlu zokuhlala bakwasebenzisa ezi paneli kwizindlu ezisebenzisa umbane ophantsi. Indlu encinci elungiselelwe kwangaphambili eneepaneli ze-PU ezingama-50 mm inokufikelela kwi-coefficient yokudlulisa ubushushu (ixabiso le-U) le-0.38 W/m²·K. Eli nqanaba lihambelana nemigangatho emininzi yendlu engasebenziyo.
Iiphaneli zesandwich ezifakwe i-insulation zidibanisa i-insulation, amandla, kunye noyilo kwinkqubo enye esebenzayo. Zinceda izakhiwo zanamhlanje zigcine amandla kwaye zihlale ziqinile. Zimela indlela elungeleleneyo phakathi kokusebenza kakuhle, ukhuseleko, kunye noyilo lwanamhlanje lwekamva lokwakha. Njengoko ulwakhiwo oluzinzileyo lukhula, iiphaneli zesandwich ezifakwe i-insulation ziya kufumana ixabiso elingakumbi.
