Mapaneru esandwich ePolyurethane, anozivikanwa sePU panels, anoshandiswa zvakanyanya mukuvaka kwemazuva ano uye mumaindasitiri nekuda kwesimba rawo, kugara kwenguva refu uye hunhu hwekupisa. Mapaneru aya akaumbwa nezvikamu zvitatu zvikuru: core yepolyurethane foam inochengetedza zvakanyanya uye yakabatana pakati pemachira maviri esimbi akasimba. Chimiro ichi chakabatana chine kugadzikana kwakanaka kwechimiro, kudzivirira kupisa uye kudzivirira mamiriro ekunze, zvichiita kuti ive yakakodzera nzvimbo dzakasiyana-siyana. Polyurethane catalysts mukugadzirwa kwemapaneru aya inoita kuti foam cores igadziriswe zvakanaka uye ishande zvakanaka.
Chii chinonzi Sandwich Panel?
Panel yesandwich rudzi rwezvinhu zvekuvaka zvinosanganisa pakati pe polyurethane foam nekunze, kazhinji simbi, kugadzira zvinhu zvine simba guru. Pakati pe foam, inogadzirwa kuburikidza nemakemikari anokonzerwa ne polyurethane catalysts, inopa insulation yakanaka, ichibatsira kuchengetedza tembiricha dzemukati dzakagadzikana muzvivakwa nemidziyo. Matinji ekunze esimbi anowedzera kuomarara, dziviriro, uye kugara kwenguva refu. Musanganiswa uyu unopa mhinduro yakareruka asi yakasimba yemadziro, matenga, nzvimbo inotonhorera, nezvimwe zvinoshandiswa uko kushanda nesimba, huremu, uye simba zvakakosha.
Basa rePolyurethane Catalysts muSandwich Panels
Zvishandiso zvepolyurethane zvakakosha pakugadzira furo remukati remasandwich panels. Zvishandiso zvakaita seMXC-T neMXC-C15, chimwe nechimwe chine hunhu hwakasiyana, zvinokurumidzisa mashandiro ari pakati pemapolyol nemaisocyanates, zvichikonzera kuumbwa kwefuro nehukuru hwaunoda uye chimiro.
1.MXC-Tinonyanya kushandiswa mukugadzira furo rakapfava rakagadzirwa nepolyether, furo rakaumbwa, furo rakati twasu, uye furo rakati twasu. Muma sandwich panels, MXC-T inobatsira kudzora chimiro chefuro, ichipa mwero wakaenzana wekuita uye chimiro chemasero chakafanana. Kuenderana uku kunovimbisa kuputira kwakafanana kwekupisa uye kunosimudzira kusimba kwechimiro chepaneru.
2.MXC-C15, chinhu chinobatsira kugadzira amine catalyst, chakanyatsokodzera kugadzira furo rakapfava uye rakapfava pamwe nekushandisa furo rakaoma. Muma sandwich panels, inobatsira pakugadzira furo rakagadzikana rinochengetedza hunhu hwaro hwekudzivirira pasi pekupisa kwakasiyana-siyana. Kudzora kweMXC-C15 pamusoro pekuita kunobatsira mukuwana huwandu hwakanaka hwefuro uye kugadzikana kwezvikamu, zvichiita kuti mapanels arambe akasimba pakukanganisika uye kushushikana kwezvakatipoteredza.
Mashandisirwo ePU Sandwich Panels
Mapaneru esandwich epolyurethane anoshandiswa zvakanyanya munzvimbo dzinochengeterwa zvinhu zvinotonhora, zvivakwa zvemaindasitiri, zvivakwa zvemabhizinesi, uye mufiriji, uko kuchengetedza kudzora tembiricha kwakakosha. Mapaneru esandwich epolyurethane akareruka, anokurumidza kuiswa, ane mutoro mudiki, uye anodzivirira mamiriro ekunze akaipisisa kwenguva yakareba. Kushandiswa kwezvinokonzera polyurethane zvakatsaurirwa mukugadzirwa kunovandudza hunhu uhwu, zvichiita kuti mapaneru esandwich epolyurethane ave sarudzo yakakura yekugadzirisa simba uye kugara kwenguva refu mukuvaka.
Muchidimbu, kusanganiswa kwefuro repolyurethane nema catalysts anoshanda zvakanyanya akadai seMXC-T neMXC-C15 kunogadzira mapaneru esandwich ane insulation yakanaka, simba uye kudzivirira mamiriro ekunze, zvichitsigira maitiro ekuvaka anogara kwenguva refu uye anoshanda.
