Kuyo yonke imarike yamandla elanga ehlabathini, izifudumezi zamanzi zelanga ezisicaba bezisoloko ziyimveliso ekhokelayo, kwaye ngaphezulu kwe-90% yeenkqubo zokufudumeza amanzi ngelanga zisebenzisa abaqokeleli belanga abacaba. Kufuneka sinikele ingqalelo kuphando kunye nophuhliso lwezifudumezi zamanzi zelanga ze-flat-panel kunye nokuphucula inqanaba lobugcisa kunye nenqanaba lamazwe ngamazwe lokusetyenziswa kwe-thermal yelanga kwilizwe lethu.
Kukho iindlela ezininzi zokuphucula ukusebenza kunye nomgangatho wabaqokeleli belanga beplate flat. Oku kulandelayo yingxoxo malunga nendlela yokuphucula ukusebenza kunye nomgangatho we-flat plate plate abaqokeleli belanga, ngokusekelwe kwizinto zokufakelwa kwe-thermal ze-flat plate solar collectors.
Umsebenzi ophambili wezinto zokukhusela ubushushu kwi-flat plate solar collector kukunciphisa ukulahleka kobushushu ukusuka kwi-collector ukuya kwindawo engqongileyo, ukuze kuphuculwe ukusebenza kakuhle kwe-collector. Ke ngoko, imfuneko ephambili yayo kukusebenza kakuhle kwe-thermal insulation, oko kukuthi, i-thermal conductivity yento incinci kwaye ayifunxi manzi. Umaleko ongaphantsi we-insulation ngokubanzi u-3 ~ 5 cm ubukhulu, kwaye ubukhulu bomaleko ongaphakathi we-insulation buyisiqingatha sezantsi.
Zeziphi izixhobo zokugquma ezidla ngokusetyenziswa kwiipleyiti ezisicaba zabaqokeleli belanga?
Izinto ezisetyenziswa ngokuqhelekileyo zokugquma i-thermal plate plate abaqokeleli belanga zibandakanya uboya bamatye, uboya bamaminerali, i-polystyrene, i-polyurethane, njl njl. Nangona kunjalo, kwizicelo eziphathekayo, ezi zixhobo zineengxaki ezahlukeneyo.
I-Polystyrene iyancipha kwiqondo lokushisa eliphezulu (ngaphezu kwe-70 ° C), ngoko ke xa isetyenziswe njengento yokukhusela ukushisa, umgca omncinci we-rock wool okanye i-mineral wool ihlala ibekwe phakathi kwayo kunye ne-plate ebamba ukushisa. Xa kusetyenziswa i-polyurethane, ubushushu kufuneka bube ngaphantsi kwe-100 ° C ixesha elide.
Nangona uboya be-rock kunye noboya beminerali bunobushushu obuphezulu bokusebenza, ukusebenza kwabo kwe-thermal insulation kulinganiselwe, kwaye ukuqhutyelwa kwe-thermal ngokuqhelekileyo yi-0.045 W / (mk), ephantsi kakhulu kune-polyurethane. Ngapha koko, imicu equlethwe kwizinto ezifana noboya bamatye kunye noboya beminerali inokubangela ubungozi kwinkqubo yokuphefumla, ulusu, kunye ne-eye mucosa yemveliso kunye nabasebenzi bokwakha. Ngaphezu koko, imicu ephalaziweyo edada emoyeni emva kokuba ichithwe ixesha elide inokubangela umonakalo emzimbeni womntu.
Ukongeza kobu bushushu bokusetyenziswa bukhankanywe ngasentla, i-polyurethane ikwajongana nemiba yokukhuselwa kokusingqongileyo efana netekhnoloji yogwebu engena-fluorine. Nangona abanye abavelisi befumene iziphumo kwitekhnoloji ye-fluorine-free-foaming, ngenxa yotyalo-mali kunye nemiba yobugcisa, kuphela iinkampani ezithile ezinoluvo oluqinileyo loxanduva lwentlalo kunye namandla ziyaphuhlisa kwaye zisebenzisa obu buchwepheshe.
Izinto zokugquma ezisetyenziswa ngokuqhelekileyo kubaqokeleli beeplati ezicaba zineengxaki ezithile, eziya kuba nefuthe elibi kubomi benkonzo, umgangatho wokusebenza kunye neminye imiba yabaqokeleli bamacwecwe.
Ke, ngaba kukho imathiriyeli yokugquma i-thermal enokoyisa zonke iingxaki zoboya bamatye, uboya bamaminerali, i-polystyrene, kunye ne-polyurethane? Impendulo yi-melamine foam.
I-Melamine foam ineempawu ezintle zokugquma ubushushu
I-Melamine foam yinkqubo yesakhiwo segridi evulekileyo ngokupheleleyo ene-triangle-dimensional ratio (L/D) phakathi kwe-10-20 kunye noxinano lwe-8.5KG/M3. Izinga lokuvula leplastiki ye-melamine foam liphezulu ukuya kuthi ga kwi-99%. Isakhiwo segridi esincinci esine-triangles ezintathu sithintela ngokufanelekileyo ukudluliselwa kobushushu bomoya. Ukongeza, ukuzinza kwayo okuncinci kobushushu kuyinika isiphumo esihle sokukhusela ubushushu (ukuqhuba ubushushu, i-0.032W/(m*K)) kwaye iyenza ibe yinto efanelekileyo kakhulu yokukhusela ubushushu kubaqokeleli be-flat-plate.
I-Melamine foam inika ubushushu obuhlala ixesha elide kunye nokumelana nomlilo
I-Melamine foam yenziwe nge-melamine resin egwetywe yi-microwave. Iqulethe i-melamine resin components, ngoko inokumelana nokushisa okuhlala ixesha elide (ukuya kuma-240 degrees Celsius ukugcina iipropati ezizinzileyo zomzimba kunye neekhemikhali) kunye nokumelana nomlilo obalaseleyo (B1, UL94 V0 kunye ne-HL-1) kunye nokusebenza kwe-insulation (akukho mbane we-static kunye ne-anti-static), ukumelana ne-asidi kunye ne-alkali, kwaye ifaneleke ngokukodwa ukugquma umqokeleli welanga. Ngelixa i-insulating kunye ne-heat-insulating, i-melamine resin foam nayo inomsebenzi ogqwesileyo wokufunxa isandi (0.95NRC), okwenza umqokeleli welanga abaleke athule, afezekise iziphumo ezininzi zokunciphisa ingxolo, ukugquma ubushushu, kunye nokugcinwa kobushushu.
I-Melamine foam i-eco-friendly
Ugwebu lweMelamine lunegwebu ikakhulu kwiresin ye-melamine polyformaldehyde. Ayiqulathanga ezinye iikhompawundi, nayo ingeyiyo ifayibha, ayiqulathanga naluphi na uthuli, ayinayo nayiphi na i-halogenated hydrocarbons, i-flame retardants, okanye isinyithi esinzima esinetyhefu, enceda ukukhusela indalo.
