Sechinhu chinochengetedza simba rekuvaka chisingadhuri, polyurethane sandwich panel yave chinhu chakakosha mumafekitori emazuva ano emaindasitiri, matura ekufambisa zvinhu, uye nzvimbo dzekuchengetera zvinhu zvinotonhora. Rudzi urwu rwepanel yekuvaka, iyo inosanganisa simbi pamusoro pevhu nezvinhu zvepolyurethane, inotarisirwa kuve yakakosha mune ramangwana.
Kushanda Kwakanaka Kwazvo
Chinhu chikuru chinobatsira pane polyurethane sandwich panel ndechekuti inoshanda zvakanaka pakudzivirira kupisa. Zvinhu zvepolyurethane foam zvine hunhu hwakanaka hwekudzivirira kupisa, uye thermal conductivity yakaderera se0.017-0.025 W/(m·K). Izvi zvinoreva kuti panel ine ukobvu hwemasendimita mashanu chete inogona kuita zvakafanana nekudzivirira kupisa semadziro ekongiri ane ukobvu hwemita imwe. Nekuda kwekushanda kwayo kwakanaka kwekudzivirira kupisa, mapaneru epolyurethane sandwich ave chinhu chinodiwa pakuvaka nzvimbo dzekuchengetera zvinhu zvinotonhora.
Kudzivirira mvura, kuramba hunyoro, uye kugadzikana kwakanyanya zvimwe zvakanakira mapaneru e polyurethane sandwich. Mwero wemasero akavharwa e polyurethane foam core unodarika 95%, zvichidzivirira kupinda kwehunyoro. Mwero wekunyudzwa kwemvura kwemapaneru e polyurethane sandwich uri pasi pe3%. Panguva imwe chete, kana tembiricha yachinja-chinja ye30°C, kushanduka kwehukuru hwemapaneru kuri pasi pe1%, zvichiita kuti ashandiswe kwenguva refu pasina kuchinja.
Kudzivirira moto kwemapaneru epolyurethane sandwich kunogona kusvika kuClass B1. Mapaneru epolyurethane sandwich anogona kutsva, asi anomira kutsva masekondi matatu chete mushure mekubviswa mumurazvo. Kunyangwe ari mashoma zvishoma pane mapaneru ematombo esandwich panhau iyi, achiri kusangana nezvinodiwa zvekuchengetedza moto.
Pachitarisiko, nekuda kwemapaneru maviri esimbi ari pamusoro nepasi, mapaneru epolyurethane sandwich ane simba rakanaka rekuvaka. Simba rekudzvanya remapaneru epolyurethane sandwich rinodarika 150 kPa. Zvisinei, chinhu chikuru ipolyurethane foam, iyo inoita kuti mapaneru ave akareruka 30-60% kupfuura zvigadzirwa zvechinyakare. Izvi zvinoita kuti mapaneru epolyurethane sandwich ave chinhu chinodiwa pakuvaka akareruka.
Kudiwa Kwakawanda Kwekugadzira
Parizvino, maitiro ekugadzira mapaneru e polyurethane sandwich anoitwa otomatiki zvakanyanya. Vagadziri vanotungamira, vakaita seHarbin Dong'an Building Sheets Co., Ltd., vanoshandisa mitsetse yekugadzira inoenderera mberi kuti ibatanidze maitiro ese ekugadzira furo, kupukuta, uye kuumba mapaneru.
Kugadzira furo rine simba guru idanho guru mukugadzirwa kwemapaneru esandwich epolyurethane. Hunhu hwefuro hunotarisa zvakananga mashandiro emapaneru. Munguva yekugadzira, vagadziri vanofanirwa kudzora tembiricha yebhodhi recheni nezvinhu zvinoputira furo. Kumhanya kwemutsetse wekugadzira kwakakoshawo, sezvo kuchikanganisa kufanana kwemaitiro ekufuridza furo.
