Polyurethane rigid foam parizvino inozivikanwa pasi rese seyakanakisa yekuvharisa zvivakwa.Iyo ine yakaderera yekupisa conductivity, yakanaka kumira mushe, simba rekukotama rakakwira, haina kunyura mvura, haina kuora, haina kurumwa nemakonzo anodyiwa zvipembenene, yakanaka retardancy uye yakakura tembiricha yekudzivirira.
Iyo komputa inoshandiswa kudzora yakazara otomatiki mutsara wekugadzira, kuitira kuti yakakwirira-tembiricha inopupuma polyurethane uye ruvara-yakavharwa simbi ndiro inoumbwa uye yakanyatsobatanidzwa.Iyo yakasimba yeruvara simbi uye yakapfava kemikari mbishi zvinhu zvakasanganiswa ne polyurethane PU furo kugadzira muchina kugadzira yazvino sainzi uye tekinoroji yekudzivirira nharaunda yekuvaka zvinhu-polyurethane (PU) ruvara simbi sandwich panel, inova chiroto chevagadziri, vagadziri uye mainjiniya.
1. Rigid polyurethane ine hunyoro-uchapupu uye isina mvura.Iyo yakavharwa sero chiyero cheiyo rigid polyurethane iri pamusoro pe90%, inova hydrophobic zvinhu uye haizowedzere iyo yekupisa conductivity nekuda kwekunyorova kwekunyorova, uye madziro emadziro haazooni mvura.
2. Hunhu polyurethane ine yakaderera thermal conductivity uye yakanaka thermal kuita.Kana iyo density ye polyurethane yakaoma iri 38 ~ 42kg/m3, thermal conductivity inongova 0.018 ~ 0.024w/(mk), iyo inenge hafu yeEPS, uye ndiyo yakaderera pakati pezvinhu zvose zvinopisa zvinopisa zvino.
3. Nemhaka yokuti polyurethane sandwich plate ine yakanakisa kupisa kupisa kushanda, pasi pezvinodiwa zvekuchengetedza kupisa, inogona kuderedza kukora kwechimiro chehamvuropu yekuvaka, nokudaro kuwedzera nzvimbo yekushandiswa kwemukati.
4. Low comprehensive cost performance.Kunyangwe iyo mutengo weyuniti yehurosi yakaoma polyurethane foam yakakwira kupfuura yezvimwe zvechinyakare zvekuvharisa zvinhu, iyo yakawedzera mutengo inozogadziriswa nekudzikiswa kwakanyanya kwemitengo yekudziya uye yekutonhodza.
