Kuyo yonke imakethe yamandla elanga emhlabeni, izifudumezi zamanzi zelanga ezinamaphaneli ayisicaba bezilokhu zingumkhiqizo ohamba phambili, futhi ngaphezu kuka-90% wezinhlelo zokushisisa amanzi ngelanga zisebenzisa iziqoqi zelanga ezinephaneli. Kufanele sinake ucwaningo nokuthuthukiswa kwezishisi zamanzi zelanga ezinamaphaneli ayisicaba futhi sithuthukise izinga lobuchwepheshe kanye nezinga lamazwe ngamazwe lokusebenzisa ukushisa kwelanga ezweni lethu.
Kunezindlela eziningi zokuthuthukisa ukusebenza kanye nekhwalithi ye-flat plate abaqoqi belanga. Okulandelayo ingxoxo mayelana nendlela yokuthuthukisa ukusebenza kanye nekhwalithi yabaqoqi be-solar plate flat, ngokusekelwe ezintweni zokushisa ezishisayo ze-flat plate solar abaqoqi.
Umsebenzi oyinhloko wezinto zokushisa eziku-flat plate solar collector ukunciphisa ukulahleka kokushisa okuvela ku-collector kuya endaweni ezungezile, ukuze kuthuthukiswe ukusebenza kahle kwe-collector. Ngakho-ke, isidingo esiyinhloko salo ukusebenza kahle kwe-thermal insulation, okungukuthi, i-thermal conductivity yento incane futhi ayimunci amanzi. Isendlalelo sokushisa esingezansi ngokuvamile siwubukhulu obungu-3 ~ 5 cm, kanti ubukhulu besendlalelo sokushisa esizungezile buyingxenye yesendlalelo.
Yiziphi izinto ezisetshenziswa kakhulu zokufaka amapuleti ayisicaba abaqoqi belanga?
Izinto ezivame ukusetshenziswa ezisetshenziselwa ukushisa okushisayo kwe-flat plate abaqoqi belanga zihlanganisa uboya bedwala, uboya bamaminerali, i-polystyrene, i-polyurethane, njll. Kodwa-ke, ekusebenzeni okungokoqobo, lezi zinto zinezinkinga ezahlukene.
I-Polystyrene iyancipha emazingeni okushisa aphezulu (ngaphezu kuka-70 ° C), ngakho-ke uma isetshenziswa njengento evimbela ukushisa, ungqimba omncane we-rock wool noma i-mineral wool uvame ukubekwa phakathi kwayo kanye nepuleti ebamba ukushisa. Uma kusetshenziswa i-polyurethane, izinga lokushisa kufanele libe ngaphansi kuka-100 ° C isikhathi eside.
Nakuba i-rock wool kanye ne-mineral wool inamazinga okushisa aphezulu okusebenza, ukusebenza kwawo kwe-thermal insulation kunomkhawulo, futhi ukuqhutshwa kwawo kwe-thermal ngokuvamile kungu-0.045 W/(mk), okuphansi kakhulu kune-polyurethane. Ngaphezu kwalokho, imicu equkethwe ezintweni ezifana ne-rock wool kanye noboya bamaminerali ingabangela ukulimala ohlelweni lokuphefumula, isikhumba, kanye ne-eye mucosa yabasebenzi bokukhiqiza nokwakha. Ngaphezu kwalokho, imicu echithiwe entanta emoyeni ngemva kokulahlwa isikhathi eside ingase ibangele ukulimala emzimbeni womuntu.
Ngaphezu kwamazinga okushisa okusetshenziswa ashiwo ngenhla, i-polyurethane iphinde ibhekane nezindaba zokuvikela imvelo njengobuchwepheshe bokugwebulwa kwe-fluorine. Nakuba abanye abakhiqizi bezuze imiphumela kubuchwepheshe obukhipha ugwebu obungenayo i-fluorine, ngenxa yokutshalwa kwezimali kanye nezinkinga zobuchwepheshe, izinkampani ezithile kuphela ezinomqondo oqinile wokuzibophezela komphakathi namandla ziyathuthuka futhi zisebenzisa lobu buchwepheshe.
Izinto zokufakelwa ezivame ukusetshenziswa eziqoqweni zamapuleti ayisicaba zinezinkinga ezithile, ezizoba nomthelela omubi empilweni yesevisi, ikhwalithi yokusebenza kanye nezinye izici zabaqoqi bamapuleti ayisicaba.
Ngakho-ke, ingabe ikhona impahla yokushisa ekwazi ukunqoba zonke izinkinga zoboya bedwala, uboya obunamaminerali, i-polystyrene, ne-polyurethane? Impendulo yi-melamine foam.
I-Melamine Foam inezindawo ezinhle kakhulu zokuvikela ukushisa
I-Melamine foam iyisistimu yesakhiwo segridi evulekile ngokuphelele enamaseli amathathu enesilinganiso segridi (L/D) esiphakathi kuka-10-20 kanye nobuningi obungu-8.5KG/M3. Izinga lokuvula lepulasitiki ye-melamine foam liphezulu kakhulu lifinyelela ku-99%. Isakhiwo segridi esihle esinezilinganiso ezintathu sivimbela ngempumelelo ukudluliselwa kokushisa komoya. Ngaphezu kwalokho, ukuzinza kwayo okuphansi kokushisa okuhlukile kuyinika umphumela omuhle wokushisa (ukuqhuba ukushisa, 0.032W/(m*K)) futhi kuyenza ibe yinto enhle kakhulu yokushisa yabaqoqi be-flat-plate.
I-Melamine Foam inikeza ukushisa okuhlala isikhathi eside nokumelana nomlilo
Igwebu le-melamine lenziwe nge-melamine resin enegwebu nge-microwave. Iqukethe izingxenye ze-melamine resin, ngakho inokumelana nokushisa okuhlala isikhathi eside (kufika ku-240 degrees Celsius ukuze igcine izakhiwo ezinzile ngokomzimba namakhemikhali) kanye nokumelana nomlilo okuhle kakhulu (B1, UL94 V0 kanye ne-HL-1) nokusebenza kwe-insulation (awukho ugesi omile kanye ne-anti-static), ukumelana ne-asidi ne-alkali, futhi ifaneleka ngokukhethekile ukufakwa kwe-solar collector. Ngenkathi i-insulating ne-heat-insulating, i-melamine resin foam iphinde ibe nokusebenza okuhle kakhulu kokumuncwa komsindo (0.95NRC), okwenza umqoqi welanga ugijime ngokuthula, ukufeza imiphumela eminingi yokunciphisa umsindo, ukwahlukanisa ukushisa, nokugcina ukushisa.
I-Melamine Foam i-eco-friendly
Igwebu le-melamine ikakhulukazi linegwebu kusuka ku-melamine polyformaldehyde resin. Ayiqukethe ezinye izinhlanganisela, iphinde ibe into engeyona i-fiber, ayiqukethe uthuli, ayiqukethe ama-halogenated hydrocarbons, ama-flame retardants, noma izinsimbi ezinzima ezinobuthi, ezisiza ukuvikela imvelo.
