Pamsika wonse wapadziko lonse lapansi wamagetsi adzuwa, zotenthetsera zamadzi zokhala ndi ma solar apansi panthaka nthawi zonse zakhala zikutsogola, ndipo zopitilira 90% zamakina otenthetsera madzi adzuwa amagwiritsa ntchito zotolera zopangira ma solar. Tiyenera kulabadira kafukufuku ndi chitukuko cha lathyathyathya-panel dzuwa zowotchera madzi ndi kukonza luso mlingo ndi mlingo wa mayiko a ntchito matenthedwe dzuwa m'dziko lathu.
Pali njira zambiri zopititsira patsogolo magwiridwe antchito ndi mtundu wa otolera ma solar plate. Zotsatirazi ndi zokambirana za momwe mungasinthire magwiridwe antchito ndi mtundu wa otolera a solar plate plate, potengera zida zodzitchinjiriza za otolera ma solar plate.
Ntchito yaikulu ya zinthu zotenthetsera kutentha mu chotenthetsera cha dzuwa cha flat plate ndikuchepetsa kutaya kutentha kuchokera ku chotenthetsera kupita ku malo ozungulira, kuti chotenthetsera chiwongolere kugwira ntchito bwino. Chifukwa chake, chofunikira chachikulu pa izi ndi magwiridwe antchito abwino a kutenthetsera kutentha, ndiko kuti, kutentha kwa zinthuzo ndi kochepa ndipo sikuyamwa madzi. Chitsulo chotenthetsera cha pansi nthawi zambiri chimakhala chakuda 3 ~ 5 cm, ndipo makulidwe a chitsulo chozungulira ndi theka la pansi.
Kodi zida zotchinjiriza zomwe zimagwiritsidwa ntchito kwambiri pakutolera ma plate solar ndi ati?
Zomwe zimagwiritsidwa ntchito nthawi zambiri zogwiritsira ntchito kutentha kwazitsulo zowonongeka kwa dzuwa zimaphatikizapo ubweya wa miyala, ubweya wa mchere, polystyrene, polyurethane, ndi zina zotero.
Polystyrene imachepa pa kutentha kwakukulu (pamwamba pa 70 ° C), choncho ikagwiritsidwa ntchito ngati zipangizo zotetezera kutentha, ubweya wonyezimira wa miyala kapena ubweya wa mchere nthawi zambiri umayikidwa pakati pake ndi mbale yotentha kutentha. Pogwiritsa ntchito polyurethane, kutentha kuyenera kukhala pansi pa 100 ° C kwa nthawi yaitali.
Ngakhale ubweya wa miyala ndi ubweya wa mchere umakhala ndi kutentha kwapamwamba kwambiri, ntchito yawo yotetezera kutentha imakhala yochepa, ndipo matenthedwe awo amatenthedwa nthawi zambiri amakhala 0.045 W/(mk), omwe ndi otsika kwambiri kuposa a polyurethane. Komanso, ulusi womwe uli muzinthu monga ubweya wa miyala ndi ubweya wa mchere ukhoza kuvulaza kupuma, khungu, ndi maso mucosa opanga ndi ogwira ntchito yomanga. Kuphatikiza apo, ulusi wokhetsedwa womwe umayandama mumlengalenga utachotsedwa kwa nthawi yayitali ukhozanso kuvulaza thupi la munthu.
Kuphatikiza pa kutentha komwe kwatchulidwa pamwambapa, polyurethane imakumananso ndi zovuta zoteteza chilengedwe monga ukadaulo wopanda thovu wopanda fluorine. Ngakhale opanga ena apeza zotsatira zaukadaulo wopanda thovu wopanda fluorine, chifukwa cha ndalama ndiukadaulo, makampani ena okha omwe ali ndi malingaliro amphamvu pazachikhalidwe komanso mphamvu akupanga ndikugwiritsa ntchito matekinoloje awa.
Zipangizo zotchingira zomwe zimagwiritsidwa ntchito kwambiri potolera mbale zafulati zimakhala ndi zovuta zina, zomwe zitha kukhala ndi vuto pa moyo wautumiki, magwiridwe antchito ndi zina za otolera mbale.
Ndiye, kodi pali zida zotchingira matenthedwe zomwe zimatha kuthana ndi zovuta zonse za ubweya wa miyala, ubweya wa mchere, polystyrene, ndi polyurethane? Yankho ndi melamine thovu.
Chithovu cha melamine chili ndi mphamvu zabwino kwambiri zotchinjiriza
Foam ya Melamine ndi dongosolo la kapangidwe ka gridi lotseguka kwathunthu la maselo atatu okhala ndi chiŵerengero cha gridi (L/D) pakati pa 10-20 ndi kuchuluka kwa 8.5KG/M3. Kutseguka kwa pulasitiki ya thovu ya melamine kuli pamwamba pa 99%. Kapangidwe ka gridi kofewa ka magawo atatu kumalepheretsa kusamutsa kutentha kwa mpweya. Kuphatikiza apo, kukhazikika kwake kwapadera kwa kutentha kochepa kumapatsa mphamvu yabwino yoteteza kutentha (kutulutsa kutentha, 0.032W/(m*K)) ndipo kumapangitsa kuti ikhale chinthu chabwino kwambiri choteteza kutentha kwa osonkhanitsa mbale zathyathyathya.
Foam ya melamine imapereka kutentha kwanthawi yayitali komanso kukana moto
Chithovu cha melamine chimapangidwa ndi utomoni wa melamine wopangidwa thovu ndi microwave. Lili ndi zigawo za utomoni wa melamine, choncho zimakhala ndi kutentha kwa nthawi yaitali (mpaka 240 digiri Celsius kuti zikhalebe zokhazikika zakuthupi ndi mankhwala) komanso kukana kwambiri kwamoto (B1, UL94 V0 ndi HL-1) ndi ntchito yotchinjiriza (palibe magetsi osasunthika ndi odana ndi malo), asidi ndi alkali kukana, ndipo ndi oyenera makamaka kutsekemera kwa dzuwa. Ngakhale kuti imateteza komanso imateteza kutentha, thovu la melamine resin limakhalanso ndi mawu omveka bwino (0.95NRC), zomwe zimapangitsa kuti chosonkhanitsa cha dzuwa chiziyenda mopanda phokoso, kukwaniritsa zotsatira zambiri za kuchepetsa phokoso, kuteteza kutentha, ndi kusunga kutentha.
Melamine thovu ndi eco-friendly
Chithovu cha melamine chimakhala chopangidwa ndi thovu la melamine polyformaldehyde resin. Zilibe zinthu zina, sizikhala ndi ulusi, zilibe fumbi, zilibe ma halogenated hydrocarbons, retardants lawi, kapena zitsulo zolemera zapoizoni, zomwe zimathandiza kuteteza chilengedwe.
