Mumusika wese wepasi rose wesimba rezuva, flat-panel solar water heaters zvagara zviri izvo zvinotungamira chigadzirwa, uye anopfuura 90% yesolar yekudziya mvura masisitimu anoshandisa flat-panel solar collectors. Isu tinofanirwa kutarisisa kutsvagurudzo uye kusimudzira kweflat-panel solar mvura hita uye nekuvandudza tekinoroji uye nhanho yepasi rose yekushandiswa kwezuva rinopisa munyika yedu.
Pane nzira dzakawanda dzekuvandudza mashandiro uye mhando yeflat plate solar collectors. Inotevera inhaurirano yemaitiro ekuvandudza mashandiro uye mhando yeflat plate solar collectors, zvichibva pane thermal insulation materials ye flat plate solar collectors.
Basa guru rechinhu chinodziisa kupisa chiri muflat plate solar collector nderekuderedza kurasikirwa kwekupisa kubva muchinhu chinodziisa kupisa kuenda kunzvimbo yakapoteredza, kuitira kuti chidziisa chishande zvakanaka. Saka, chinodiwa chikuru pairi ndechekushanda zvakanaka kwechinhu chinodziisa kupisa, kureva kuti, thermal conductivity yezvinhu zvacho idiki uye haitore mvura. Chidziisa chepasi chinowanzova neukobvu hwe3 ~ 5 cm, uye ukobvu hwechidziisa chepasi chinenge hafu yepasi.
Ndeapi anowanzo shandiswa insulation zvinhu zve flat plate solar collectors?
Inowanzo shandiswa thermal insulation materials for flat plate solar collectors zvinosanganisira rock wool, mineral wool, polystyrene, polyurethane, etc. Zvisinei, mukushanda kwekushanda, zvinhu izvi zvine matambudziko akasiyana.
Polystyrene inoderera pakupisa kwepamusoro (pamusoro pe70 ° C), saka kana inoshandiswa sechinhu chinopisa-chinopisa, tsvina yakaonda yematombo ematombo kana mineral wool inowanzoiswa pakati payo neplate inobata kupisa. Kana polyurethane inoshandiswa, tembiricha inofanira kunge iri pasi pe100 ° C kwenguva yakareba.
Kunyange zvazvo rock wool nemineral wool zvine tembiricha yekushanda yakakwira, kuita kwavo kupisa kwemafuta kunogumira, uye kudziya kwavo kunowanzoita 0.045 W/(mk), iyo yakadzikira zvakanyanya kupfuura iyo yepolyurethane. Uyezve, mafiber ari mumidziyo yakaita sedombo remvere uye mineral wool anogona kukonzera kukuvadza kune yekufema system, ganda, uye ziso mucosa yekugadzira nevashandi vekuvaka. Uyezve, mafiibhi eakadururwa anoyangarara mumhepo mushure mekurukwa kwenguva yakareba anogonawo kukuvadza muviri wemunhu.
Kuwedzera kune yataurwa pamusoro tembiricha yekushandiswa, polyurethane zvakare inotarisana nekuchengetedzwa kwezvakatipoteredza senge fluorine-isina furo tekinoroji. Kunyangwe vamwe vagadziri vakawana mhedzisiro mune fluorine-isina furo tekinoroji, nekuda kwekudyara uye nenyaya dzehunyanzvi, mamwe makambani chete ane pfungwa yakasimba yemagariro uye simba ari kuvandudza nekushandisa matekinoroji aya.
Zvishandiso zvekudzivirira zvinowanzoshandiswa mumaplati ekutakura ane mamwe matambudziko, ayo anozove nemhedzisiro yakaipa pahupenyu hwesevhisi, hunhu hwekuita uye zvimwe zvinhu zvevatakuri veplate flat.
Saka, pane here thermal insulation material inogona kukurira matambudziko ese e rock wool, mineral wool, polystyrene, uye polyurethane? Mhinduro ndeye melamine foam.
Melamine foam ine yakanakisa yekupisa yekuvharisa zvivakwa
Foam yeMelamine isystem yekuvaka grid ine mativi matatu yakavhurika ine grid aspect ratio (L/D) iri pakati pe10-20 uye density ye8.5KG/M3. Kuvhurwa kwepurasitiki yefoam yemelamine kwakakwira kusvika pamusoro pe99%. Chimiro chegrid chetatu-mativi chakapfava chinodzivirira kutamiswa kwemhepo nekupisa. Pamusoro pezvo, kugadzikana kwayo kwekupisa kwakaderera kunoipa simba rakanaka rekudzivirira kupisa (thermal conductivity, 0.032W/(m*K)) uye inoita kuti ive chinhu chakanaka kwazvo chekudzivirira kupisa kune vanounganidza maplate akatsetseka.
Melamine foam inopa kupisa kwenguva refu uye kudzivirira moto
Melamine foam inogadzirwa nemelamine resin inopupuma nemicrowave. Iine melamine resin components, saka ine inogara kwenguva refu kupisa kwekudzivirira (kusvika 240 madhigirii celsius kuchengetedza kugadzikana kwemuviri uye kemikari zvinhu) uye yakanakisa moto inodzivirira (B1, UL94 V0 uye HL-1) uye insulation performance (hapana static magetsi uye anti-static), asidhi uye alkali kuramba, uye inonyanya kukodzera kupisa muunganidzi wezuva. Ichiri insulating uye kupisa-kupisa, melamine resin foam inewo yakanakisa kurira kwekuita (0.95NRC), ichiita kuti muunganidzi wezuva amhanye akanyarara, achiwana akawanda mhedzisiro yekuderedza ruzha, kupisa kupisa, uye kuchengetedza kupisa.
Melamine furo ine eco-friendly
Melamine furo rinonyanya kupushwa kubva kumelamine polyformaldehyde resin. Iyo haina mamwe makomisheni, zvakare isiri-fiber zvinhu, haina chero huruva, haina chero halogenated hydrocarbons, flame retardants, kana chepfu inorema simbi, inobatsira kuchengetedza zvakatipoteredza.
