Zvishandiso zvepolyurethane zvinoita basa guru mukugadzirwa kwemapaneru esandwich epolyurethane, ayo anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwehunhu hwawo hwakanaka hwekuputira, kusimba kwechimiro, uye hunhu hwawo hwakareruka. Kunzwisisa mashandisirwo emakaneru aya kunogona kupa ruzivo rwakadzama pamusoro pemaitiro ekugadzira uye mabhenefiti ekushandisa mapaneru esandwich epolyurethane.
Chii chinonzi Sandwich Panel?
Panel yesandwich inowanzo kuve nezvikamu zvitatu: core ine density yakaderera yakagadzirwa ne polyurethane rigid foam uye mapepa maviri ekunze anopa rutsigiro nekudzivirira chimiro. Chinhu chepakati, polyurethane rigid foam, inosarudzwa nekuda kwehunhu hwayo hwepamusoro hwekupisa, hunhu hwayo hwakareruka, uye simba remuchina. Mapepa ekunze anogona kugadzirwa nezvinhu zvakasiyana-siyana, zvinosanganisira PPGI (pre-coated galvanized iron), PPGL (pre-coated aluminized zinc iron), mapepa ealuminium, kana mapepa epepa. Mapepa aya anoumbwa kana kuvharwa zvichienderana nezvinodiwa nemuchina wekugadzira roller, zvichigadzira panel yakasimba uye inodzivirirwa.
Basa rePolyurethane Catalysts
Zvinhu zvinokonzeresa polyurethane zvakaita seMXC-Tuye MXC-BDMA zvakakosha mukugadzirwa kwefuro rakagadzika repolyurethane, iro rinoumba musimboti wemapaneru esandwich. Macatalyst aya anobatsira kuita kwemakemikari pakati pema precursor epolyurethane, zvichiita kuti pave nepolymer ine huremu hwakawanda. Kazhinji, zvikamu zvina kana kupfuura zvemvura zvine ma precursor epolyurethane zvinoyerwa uye zvinosanganiswa panguva yekugadzirisa kuti zvigadzire furo repolyurethane. Basa rema catalyst nderekukurumidzira maitiro aya, kuve nechokwadi chekuumbwa kwefuro kunoshanda uye kunodzorwa.
Maitiro Ekugadzira
Kugadzirwa kwemapaneru e polyurethane sandwich kunosanganisira matanho akati wandei:
1. Kuyera uye Kusanganisa: Zvikamu zvemvura zvine polyurethane precursors zvinoyerwa uye zvinosanganiswa nemazvo. Danho iri rakakosha pakuzadzisa hunhu hwefuro rinodiwa.
2. Kugadzira Furo: Zvinhu zvakasanganiswa zvinoitwa nefuro, zvichibatsirwa nema catalysts MXC-T neMXC-BDMA. Ma catalysts aya anoita kuti furo riitike nekukurumidza, zvichigadzira furo rakafanana uye remhando yepamusoro.
3. Lamination: Furo iri pakati pemachira maviri ekunze, ayo anogadzirwa kana kuvharwa zvichienderana nezvinodiwa nemuchina wekugadzira roller.
4. Kugadzirisa: Panel yesandwich yakaunganidzwa inogadziriswa kuti furo rikwanise kukura zvakakwana uye kunamira pamapepa ekunze, zvichiita kuti chimiro chakasimba uye chigadzikane.
Mabhenefiti ePolyurethane Sandwich Panels
1. Kudzivirira Kupisa: Furo rakasimba repolyurethane rinopa kudzivirira kupisa kwakanaka, zvichiita kuti mapaneru esandwich ave akakodzera kushandiswa uko kudzora tembiricha kwakakosha.
2. Simba reChivako: Kusanganiswa kwepakati pefuro rakasimba uye machira ekunze akasimba zvinopa simba rakawanda rechivako, zvichiita kuti mapaneru akodzere kushandiswa pakutakura mutoro.
3. Zvishoma: Pasinei nekusimba kwazvo, mapaneru e polyurethane sandwich akareruka, zvichideredza mari yekufambisa uye yekuisa.
4. Kushandiswa Kwakawanda: Mapaneru aya anogona kushandiswa mumabasa akasiyana-siyana, kusanganisira kuvaka zvivako, mafiriji, uye kutakura.
Mhedziso
Zvinhu zvinokonzeresa kushanduka kwepolyurethane zvakaita seMXC-T uyeMXC-BDMAzvakakosha pakugadzirwa kwemapaneru e polyurethane sandwich emhando yepamusoro. Mapaneru aya ane mabhenefiti akasiyana-siyana, anosanganisira kupisa kwakanyanya, kusimba kwechimiro, uye kushanduka-shanduka. Kunzwisisa basa rema catalysts mukugadzirwa kunoratidza kukosha kwekuita kwemakemikari chaiwo mukugadzira zvinhu zvinosangana nezvinodiwa neindasitiri uye zvinodiwa pakushandiswa. Semupi we polyurethane catalysts, tinova nechokwadi chekuti zvigadzirwa zvedu zvinobatsira mukugadzirwa kwakanaka uye kunobudirira kwemapaneru e polyurethane sandwich, zvichitsigira maindasitiri akasiyana-siyana mukuzadzisa zvinangwa zvavo zve insulation uye zvekuvaka.
