Polyurethane foam ndeye yakakwira molecular polymer.Chigadzirwa chakagadzirwa kubva ku polyurethane uye polyether iyo yakasanganiswa zvine hunyanzvi.Parizvino, pane mhando mbiri dzefuro rinoshanduka uye furo rakaomarara pamusika.Pakati pavo, furo rakaomarara rakavharika-sero chimiro, nepo furo rinochinjika iri rakavhurika-sero chimiro.Zvimiro zvakasiyana zvine nzvimbo dzakasiyana dzekushandisa.
Tbasa re polyurethane foam
Polyurethane foam inogona kuita basa rekuchengetedza.Ingave furo rakaomarara kana furo rinochinjika, zvinhu zvacho zvakanaka uye zvinogona kuvharwa.Ehe, inogona zvakare kuve neruzha rwekudzivirira mhedzisiro, uye inogona kushandiswa mune mamwe minda kuparadzanisa mamwe manzwi zvakanaka.Low thermal conductivity uye yakanaka thermal insulation performance.Mune iyo yakaoma furo ye polyurethane foam, pane zvinhu zvine kupisa kwekupisa uye mabasa asina mvura, izvo zvinoderedza kupisa kwekushisa.Mune mamwe minda, yakadai yakaderera yekupisa conductivity inofuridza agent inodiwa, uye mamwe anonamira haana kukodzera kushandiswa.
Theapplicationye polyurethane foam
Kuchengetedza magetsi uye kuchengetedza kwezvakatipoteredza.Sekuzadza, gaka rinogona kuzadzwa zvakakwana, uye kuita kwekunamatira kunogona kuwanikwa.Mushure mekuporesa, inogona kunamatira zvakasimba uye ine hupenyu hurefu hwebasa.
Compression uye shockproof.Kana iyo polyurethane foam yanyatsopora, hapazove nekutsemuka, ngura uye peeling.Iine huwandu hwakawanda hwekushandisa uye huwandu hwakawanda hwekushandisa.Inogona kushandiswa musimba idzva, indasitiri yemauto, kurapwa, kubhururuka kwendege, ngarava, zvemagetsi, mota, zviridzwa, magetsi emagetsi, njanji inomhanya, nezvimwewo, ine yakaderera conductivity, yakanaka kupisa kupisa, uye kuchengetedza kupisa.Inoshandiswa mumagetsi, magetsi uye mamwe minda, inogona kurwisa zvakanyanya tembiricha nharaunda uye kuita thermal insulation performance.
Soundproofing uye insulating.Kana iyo polyurethane foam yapora zvachose, inogona kuve yakanyatso hunyoro-uchapupu uye kusapinda mvura.Kunyange munzvimbo ine rima uye ine mwando, hapazovi nematambudziko.
Matambudziko akajairika uye matanho ekudzivirira e polyurethane foam
