Izakhiwo zesimanje zidinga izinto ezonga amandla futhi ezihlala ziqinile futhi zivikela umswakamaamaphaneli esandwichbahlangabezana nalesi sidingo. Bahlanganisa ukufudumala, isakhiwo, kanye nomklamo ohlelweni olulodwa. Abakhi bawasebenzisela izindawo zokugcina impahla, amafektri, kanye namakamelo okubanda.
Amaphaneli asebenza kahle ezimweni nasezimweni ezahlukahlukene. Akha izimbobo zokwakha ezihlala isikhathi eside nezisebenzisa amandla kahle. Ukusebenza kahle kwazo ekushiseni kanye nokuphepha komlilo kuzenza zilungele amaphrojekthi esimanje.
Indima Yamaphaneli Esandwich Afakwe Ukushisa
Iphaneli ngayinye yesangweji evalekile inamashidi amabili ensimbi ane-core yokuvikela ukushisa. Lesi sakhiwo sinciphisa ukudluliselwa kokushisa futhi sinikeza ukuqina okuphezulu.
Amaphaneli esandwich afakwe ugesi asebenza izindima eziningi ekwakhiweni kwezakhiwo zanamuhla. Umsebenzi wawo oyinhloko ukulawula izinga lokushisa ngaphakathi kwezakhiwo. I-insulation core inciphisa ukulahleka kokushisa ebusika kanye nokwanda kokushisa ehlobo. Lokhu kunciphisa ukusetshenziswa kwamandla okushisa nokupholisa. Izifundo zibonisa ukuthi izakhiwo ezisebenzisa amaphaneli afakwe ugesi zingonga amandla angu-30% kuya ku-50% uma kuqhathaniswa nezindonga ezivamile.
Ziphinde zinciphise ukudluliswa komsindo. Amafektri amaningi kanye nama-workshop adinga izimo zokusebenza ezithule. Isakhiwo sephaneli esiminyene sivimba umsindo ngempumelelo. Iphaneli ye-polyurethane engu-50 mm inganciphisa umsindo cishe ngo-25 dB.
Enye indima ebalulekile ukuvikela. Ubuso bensimbi buyamelana nomoya, imvula, nokugqwala. Buvikela izinto zokuvikela futhi bugcina uhlelo luzinzile. Ungqimba lwangaphandle oluqinile luvumela amaphaneli ukuthi aphathe imithwalo esindayo. Lokhu kuwasiza ukuthi ahlale amashumi eminyaka ngaphandle kokunakekelwa okuningi.
Ezindaweni zokugcina izinto ezibandayo kanye namakamelo ahlanzekile, amaphaneli agcina izinga lokushisa elilinganayo kanye nokuhlanzeka. Avimbela umswakama kanye nokukhula kwamagciwane ngokusebenzisa izindawo zawo ezibushelelezi, ezingenazo izimbobo. Amalunga aphakathi kwamaphaneli aqinile, okuthuthukisa ukuvalwa komoya.
Abaklami bezakhiwo basebenzisa la maphaneli ukudala izakhiwo ezisebenzisa amandla amaningi, ezilula, nezihlala isikhathi eside. Uhlelo luhlanganisa ukufudumala, isakhiwo, kanye nobuhle. Abakhi bonga isikhathi njengoba amaphaneli eza esenziwe kusengaphambili ngosayizi ozinzile. Ingxenye ngayinye ingangena ngokushesha endaweni, okunciphisa izindleko zomsebenzi.
Izici Eziyinhloko
Amaphaneli esandwich afakwe i-insulation anezici eziningana eziphawulekayo. I-insulation yawo yokushisa iyisici esibaluleke kakhulu. Ingaphakathi livame ukusebenzisa i-polyurethane (PU), i-polyisocyanurate (PIR), noma uboya bedwala. Indwangu ngayinye inikeza ukusebenza okuhlukile kokushisa.
Amaphaneli e-PU anokudluliswa kokushisa okungaba ngu-0.022 W/m·K, okusho ukuthi ukuvikela okuhle kakhulu. Ama-PIR cores anikeza ukumelana okuphezulu komlilo nokusebenza kwamandla okufanayo.
Amaphaneli aphinde anikeze amandla aphezulu okusebenza. Izikhumba zensimbi zabelana ngemithwalo nomongo, zakha isakhiwo esihlanganisiwe esizinzile. Iphaneli ye-PU enobuso bensimbi obuyi-100 mm ubukhulu ingathwala ingcindezi efika ku-150 kPa. Lokhu kuqina kuyenza ifaneleke ophahleni, ezindongeni nasezindlini ezibandayo.
Esinye isici esibalulekile ukumelana nomlilo. Ama-PIR kanye nama-rock wool cores angafinyelela amazinga omlilo e-Class B1 noma e-Class A. Abambezela ukusabalala komlilo futhi anciphise ukukhishwa kwentuthu. Isibonelo, iphaneli yoboya be-rock engu-75 mm ingamelana nomlilo imizuzu engaphezu kwengu-60.
Ukuqina kwazo kuyamangalisa ngendlela efanayo. Amashidi ensimbi, avame ukuba yinsimbi egqitshwe nge-galvanized noma embozwe nge-coated, amelana nokugqwala kanye nomswakama. Abakhiqizi abaningi basebenzisa izembozo ze-polyester noma ze-PVDF ukuze bandise impilo yomphezulu ngaphezu kweminyaka engama-20.
Ngaphezu kwalokho, lawa maphaneli anikeza ukuguquguquka kobuhle. Afika ngemibala ehlukahlukene, amaphrofayili, kanye nokuqedwa. Izindawo ezibushelelezi, ezinemicu, noma ezimboziwe zingahambisana nezintandokazi ezahlukene zomklamo.
Okokugcina, ukulula kokufaka kwengeza inani elengeziwe. Amaphaneli alula futhi kulula ukuwaphatha. Abakhi basebenzisa izibambo ezifihliwe nezinhlelo zokuxhuma ukuze bakhe imigqa ehlanzekile. Lokhu kunciphisa isikhathi sokwakha futhi kuqinisekisa ukuqeda okuhle.
Ukunaka Kokukhiqiza
Ukukhiqizwa kwamaphaneli e-sandwich agqunywe ngokushisa kudinga ukulawulwa okuqinile. Isigaba ngasinye sithinta ukusebenza kanye nekhwalithi. Abakhiqizi baqala ngamashidi ensimbi asezingeni eliphezulu. Insimbi kufanele ibe ne-zinc coating efanele ukuvimbela ukugqwala. Ubukhulu buvame ukusuka ku-0.4 mm kuya ku-0.8 mm kuye ngomklamo.
Okulandelayo kulandela ukwelashwa kwendawo. Indawo yensimbi kumele ihlale ihlanzekile futhi yomile ngaphambi kokumboza. Noma yimuphi uwoyela, uthuli, noma ukugqwala kungathinta ukunamathela. Ingubo esezingeni eliphezulu, njenge-PVDF noma i-polyester, yandisa ukumelana nesimo sezulu.
Ingaphakathi lokuvikela lidinga ukwakheka kwezinto eziqondile. Ku-PU kanye ne-PIR, isilinganiso samakhemikhali kanye nokulawula izinga lokushisa kubalulekile. Ngisho nephutha elincane linganciphisa ukuminyana kwe-foam noma lidale izikhala. Amaphaneli oboya bedwala adinga ukuqondiswa okufanele kwefayibha kanye nokuminyana ukuze alondoloze ukusebenza okungashi.
Ngesikhathi sokukhiqiza okuqhubekayo, igwebu noma izinto eziyinhloko zingena phakathi kwamashidi ensimbi. Inqubo idinga ukucindezela okunembile nokulawulwa kwesivinini. Ukufakwa kwe-lamination okungalingani kungenza buthaka isibopho phakathi kwengxenye eyinhloko nesikhumba. Imigqa yokukhiqiza ethuthukisiwe isebenzisa izinhlelo zokushisa ezizenzakalelayo kanye nezinhlelo zokucindezela ukuqinisekisa ikhwalithi efanayo.
Ukuvalwa kokusika nokusemaphethelweni nakho kudinga ukunakekelwa. Amajoyinti anquma ukuqina kokushisa nomoya. Isikhala esincane singabangela ukujiya kanye nokuvuza kokushisa. Abakhiqizi bavame ukusebenzisa ukuxhumana kolimi nomsele noma izikulufo ezifihliwe ukuze bathuthukise ukuvalwa.
Ukuhlolwa kwekhwalithi kuqedela inqubo. Amaphaneli ahlolwa ukujiya, ukujiya, ukunamathela, amandla okugoba, kanye nokuziphatha komlilo. Idatha iqinisekisa ukuthi umkhiqizo uhlangabezana nezindinganiso zikazwelonke nezamazwe ngamazwe.
Ukupakishwa kanye nokuthuthwa okufanele kugcina amaphaneli ephephile ngaphambi kokufakwa. Umthelela womshini ngesikhathi sokulethwa ungalimaza imiphetho noma uqweqwe. Ngakho-ke, amaphaneli abekwa phansi futhi asongwe ngefilimu evikelayo.
Impendulo yephrojekthi
I-Harbin Dong`an Building Sheets Co., Ltdungumkhiqizi ohamba phambili wephaneli yesandwich eShayina. Inkampani iDong`an inamaphrojekthi amaningi angempela amaphaneli esandwich agqunywe ngokushisa. La maphrojekthi abonisa amandla amaphaneli esandwich agqunywe ngokushisa.
Endlini yokugcina impahla eyakhiwe eMalaysia, onjiniyela basebenzise amaphaneli e-PIR angu-100 mm ophahleni kanye nama-75 mm odongeni. Isakhiwo sathola ukonga amandla ngo-45% uma kuqhathaniswa nezindonga zamabhulokhi ezivamile ezivalekile. Izinga lokushisa langaphakathi lahlala lizinzile ngaphakathi kuka-±2 °C ngisho nangaphansi kwelanga eliqondile.
Isitshalo sokugcina izinto ezibandayo ePhilippines sasebenzisa amaphaneli e-PU angu-150 mm emakamelweni aqandisayo. Izinga lokushisa langaphakathi lahlala ku-−25 °C ngokushintshashintsha okungu-3 °C kuphela ngosuku. Ukusetshenziswa kwamandla kwehle ngo-30% ngemva kokushintsha amabhodi okushisa amadala.
EYurophu naseRussia, amaphaneli esandwich oboya bedwala adumile ezimbonini ngenxa yokuphepha komlilo. Indawo yokusebenzela engamamitha-skwele angu-1,200 esebenzisa amaphaneli oboya bedwala angu-80 mm ihlangabezane nezindinganiso zomlilo ze-EN 13501 Class A. Ukumelana nomlilo kwathatha imizuzu engaphezu kwama-90 ezivivinyweni.
Abakhi bezindlu zokuhlala nabo basebenzisa la maphaneli emakhaya asebenzisa amandla ngendlela eyongayo. Indlu encane efakwe kusengaphambili enamaphaneli e-PU angu-50 mm ingafinyelela i-coefficient yokudlulisa ukushisa (inani lika-U) elingu-0.38 W/m²·K. Leli zinga lihambisana nezindinganiso eziningi zendlu ezingasebenzi.
Amaphaneli esandwich afakwe ugesi ahlanganisa ugesi, amandla, kanye nomklamo ohlelweni olulodwa olusebenzayo. Asiza izakhiwo zesimanje ukuthi zonge amandla futhi zihlale ziqinile. Amelela indlela elinganiselayo phakathi kokusebenza kahle, ukuphepha, kanye nomklamo wesimanje wesikhathi esizayo sokwakha. Njengoba ukwakhiwa okusimeme kukhula, amaphaneli esandwich afakwe ugesi azothola inani elikhulu nakakhulu.
