'Uphahla oluqaqambileyo' lwezakhiwo zemizi-mveliso: Izibane zeFRP

Isizathu sokuba i-FRP (i-fiberglass eyomeleziweyo yeplastiki) izibane zasesibhakabhakeni zinokuba "luphahla oluqaqambileyo" lwezakhiwo zemizi-mveliso kukuba zihlangabezana ngokugqibeleleyo nezona mfuno zingundoqo zemeko yemizi-mveliso -enkulu yokukhanya kwendawo, amandla aphezulu kunye nokuqina, kunye neendleko zokuzilungisa eziphantsi. Bangakwazi ukucombulula iintlungu zeentlungu zesibhakabhaka zendabuko kunye nokuphucula ukusebenza kakuhle kwezakhiwo zoshishino.

1. Ukusombulula iingxaki zokukhanyisa ezingundoqo kwizakhiwo zoshishino

Izakhiwo zemizi-mveliso ziphawulwa "ngobude obukhulu, isilingi ephezulu, kunye nexesha elide lokusebenza", elibeka iimfuno eziphakamileyo kakhulu "kukufaniswa, ukuzinza kunye nokugubungela" ukukhanya. I-FRP (iplastiki ye-fiberglass eyomeleziweyo) iipaneli zokukhanya kwemini zinokuhlangabezana ngokuchanekileyo ezi mfuno.

Ukukhanya okubanzi okuxutyiweyo, ilitha-elikhululekileyo nangaphandle kwamabala angaboniyo: FRP (fiberglass reinforced plastic) ukukhanya{1}}iipaneli zokuhambisa zine-75% -85% yokukhanya, kwaye ukukhanya kuyasasazwa emva kokusasazwa yifiberglass, kuthintelwa ilitha elenzeka ngeglasi. Kwanakwizakhiwo zomzi-mveliso ezinobude obungaphezu kweemitha ezili-10, ukukhanya kunokugquma ngokulinganayo imigca yokuvelisa, iindawo zokugcina, kunye nezinye iindawo, ukunciphisa iimpazamo zokusebenza ezibangelwa kukungonelanga kokukhanyisa kwendawo.

Ilungelelaniswa nezakhiwo ezinkulu-ezinokhuselo olungenamsebenzi: Izibane zesibhakabhaka ze-FRP zinokwenziwa ngokwezifiso ngobude kwaye zinokwahlulwa ngokwepateni yamaza ukuze zivumelane nobubanzi obungaxhaswanga beemitha ezingama-30 nangaphezulu. Ngokungafaniyo neglasi, akufuneki ukuba zahlulwe zibe ngamaqhekeza amancinci ukuze kufakwe, kuncitshiswe iziphazamiso zokukhanya ezibangelwa kukuqhawuka kwemithungo, zizenze zifaneleke ngakumbi-izakhiwo zendawo ezifana neefektri zentsimbi kunye neendawo zokugcina iimpahla.

Ixesha elide{0}}losasazo lokukhanya oluzinzileyo kunye nesantya esisezantsi sokuthomalalisa kwisithuba seminyaka elishumi: Ukuhanjiswa kokukhanya kwezibane zeplastiki eziqhelekileyo kuya kuhla nge-30% kwi-3{3}}iminyaka emi-5, ngelixa i-FRP skylights, nge-surface anti-UV yokugquma, inokulawula izinga lokunciphisa ukukhanya ukuya Ngaphantsi kwe-2% ngonyaka okanye ilingana. Ngaphantsi kokusetyenziswa okuqhelekileyo kwiminyaka eyi-15, basenokugcina ukukhanya okungaphezulu kwe-60%, ukuphepha imfuno yokutshintshwa rhoqo kweepaneli kwizakhiwo zoshishino ngenxa yokukhanya okunganeleyo.

2. Ukumelana novavanyo lwe-"hardcore" yendawo yoshishino

Izakhiwo zemizi-mveliso zihlala zijongana nemekobume erhabaxa njengerhasi ezonakalisayo, iimpembelelo zento enzima, kunye nemozulu embi. Iimpawu ezibonakalayo ze-FRP (i-fiberglass eyomeleziweyo yeplastiki) i-skylights inokujongana ngqo nale mingeni, ukunciphisa ubungozi bokhuseleko kunye neendleko zokugcina.

I-Corrosion{0}}iyaxhathisa kunye ne-asidi kunye ne-alkali{1}}iyaxhathisa, ilungele iindibano zocweyo ezikhethekileyo: Imichiza, i-electroplating, i-pickling kunye nezinye iindibano zocweyo zinokukhupha iasidi kunye neegesi zealkali. Iglasi eqhelekileyo igqwala ngokulula kwaye iyangunda, ngelixa iiphaneli zeFRP ezikhanyayo zinokwenziwa ngevinyl ester resin, ephucula ukuxhathisa kweasidi kunye nealkali ngama-3{5}}5 amaxesha. Ngokusetyenziswa kwexesha elide, umphezulu awuyi kubhobhoza okanye udilize, kwaye akukho mfuneko yokususwa kwerusi rhoqo okanye ukutshintshwa.

Ukumelana nempembelelo ephezulu, ungoyiki umonakalo wengozi: Izityalo zemizi-mveliso zihlala zinemisebenzi efana nokuphatha i-forklift kunye nokuphakanyiswa koomatshini. Ukumelana nempembelelo ye-FRP skylights ngamaxesha angama-2-3 eglasi. Nokuba ubethwe zizinto ezinzima okanye udibana nesichotho, iya kukhubaza kuphela kwindawo endaweni yokuqhekeka, ukuthintela umonakalo wesixhobo okanye ukwenzakala komntu okubangelwa yiglasi eyaphukileyo.

Ukumelana nemozulu kulungelelaniswa neemozulu ezikhethekileyo: Nokuba kukwingqele egqithisileyo - ye-30℃okanye kuxinzelelo lomoya olunamandla lwezaqhwithi, izibane zeFRP zinokugcina ukusebenza okuzinzileyo. Ukushisa kwayo okuphantsi kwe-embrittlement iqondo eliphantsi lingaphantsi okanye lilingana ne--40 degree, kunye nokumelana nomthwalo womoya kunokufikelela kwi-2.5kPa, okwenza kube lula kwizakhiwo zoshishino kwiindawo ezahlukeneyo zemozulu ezifana neendawo ezinxweme kunye namathafa.

3. Ukunciphisa iindleko zizonke zobomi bezakhiwo zemizi-mveliso.

Izakhiwo zemizi-mveliso zibeka phambili "iindleko-zokusebenza kakuhle" kunye "nobuchule bokusebenza." I-FRP (i-fiberglass eyomeleziweyo yeplastiki) i-skylights inokunciphisa kakhulu iindleko ukusuka kufakelo lokuqala ukuya kugcino lwamva, ukulungelelaniswa nengqiqo yolawulo lweendleko zeeprojekthi zoshishino.

Ufakelo olukhaphukhaphu lugcina iindleko zesakhiwo kunye nezabasebenzi: Izibane zesibhakabhaka ze-FRP zinobunzima besiqingatha kuphela njengeglasi, zisusa imfuneko yeefreyimu zentsimbi enzima kunye neekhreyini ezifana nofakelo lweglasi. Iphaneli enye inokushukunyiswa ngabantu aba-2-3, kwaye ixesha lokufakela i-10,000 square metres ye-skylight lingafinyelelwa kwiintsuku ze-3-5, ukwandisa ukusebenza kakuhle kofakelo nge-50% xa kuthelekiswa neglasi, ukunciphisa ngokuthe ngqo iindleko zomsebenzi kunye nezixhobo zokurenta.

Ukugcinwa okuphantsi kwaye akukho kutshintshwa okufunekayo, ukunciphisa ilahleko yokunciphisa ixesha: I-FRP (i-fiberglass eyomeleziweyo yeplastiki) i-skylights ingasetyenziselwa ngokuqhelekileyo iminyaka eyi-15-25 ngaphandle kokutshintshwa, ifuna ukucocwa kuphela ngonyaka okulula kothuli lomhlaba. Xa kuthelekiswa neepaneli zeplastiki eziqhelekileyo ekufuneka zitshintshwe rhoqo emva kweminyaka emi-3 ukuya kwemi-5, oku kunqanda ilahleko yexesha eliphantsi kwimigca yemveliso yemizi-mveliso ngenxa yokutshintshwa kwezinto zokukhanya kwesibhakabhaka, nto leyo ibaluleke kakhulu kwiinkampani ezineenkqubo zokuvelisa eziqhubekayo ezifana nokwenziwa kweekhemikhali kunye neemoto.

Ukonga amandla kunye nokunciphisa ukusetyenziswa, ukugcinwa kwexesha elide kwiindleko zokusebenza: I-coefficient yokufakelwa kwe-thermal ye-FRP skylights (0.18W/(m・K)) ingaphantsi kakhulu kuneglasi (0.76W/(m・K)), enokunciphisa ukuqokelelwa kobushushu kumzi mveliso ehlotyeni kwaye inciphise umthwalo we-air conditioning nge-15%; ngelo xesha, ukuhanjiswa kokukhanya okuphezulu kunokutshintsha i-40% -60% yokukhanyisa okwenziweyo. Ngokusekelwe kwi-10,000㎡ mveliso, inokugcina malunga ne-80,000-120,000 yuan kwiindleko zombane ngonyaka.
