Mapaneru esandwich ave chinhu chikuru mukuvaka kwemazuva ano, anozivikanwa nekukwanisa kwawo kusanganisa simba, kuputira, uye kushanduka-shanduka. Mapaneru aya, ane core insulation layer yakasungirirwa pakati pezvikamu zviviri zvezvinhu zvinogara kwenguva refu, anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwekupisa kwawo kwakanaka uye mabhenefiti ekuvaka.
Chimwe chezvinhu zvinonyanya kufarirwa zvema sandwich panels ipolyurethane, inozivikanwa nekudzika kwekupisa kwayo, iyo inopa insulation yakanaka yekupisa. Izvi zvinoita kuti ma polyurethane sandwich panels ashande zvakanyanya mukushandiswa uko kushandiswa kwesimba kuri chinhu chinonyanya kukosheswa. Semuenzaniso, mukugadzirisa zvivakwa, ma sandwich aya anowanzo shandiswa padenga uye insulation yekunze yemadziro, zvichibatsira kuchengetedza tembiricha yemukati yakagadzikana uye kuderedza kushandiswa kwesimba.
Munzvimbo dzemaindasitiri, mapaneru esandwich anowanzo shandiswa mukuvaka mafekitori, matura, nenzvimbo dzekuchengetera zvinhu zvinotonhora. Hunhu hwemapaneru aya hunobatsira kuchengetedza nzvimbo dzakadzorwa, kungave kudzivirira kupisa kana kuona kuti mhepo inotonhora inoramba iripo. Izvi zvinoita kuti ave akakosha mumaindasitiri akadai sekugadzira chikafu nemishonga, uko kudzora tembiricha kwakakosha.
Kushandiswa kwema sandwich panels kunodarika kungodzivirira moto chete. Anodzivirirawo moto zvakanyanya, anochengetedza ruzha, uye anogara kwenguva refu, zvichiita kuti akwanise kushandiswa zvakasiyana-siyana, kusanganisira zvivako zvemahofisi, nzvimbo dzezvitoro, uye kunyange dzimba dzekugara. Kureruka kwema sandwich panels aya kunoitawo kuti zvive nyore kubata nekuisa, zvichideredza nguva yekuvaka nemari yevashandi.
Semutengesi wezvinokonzeresa polyurethane, tinopa zvigadzirwa zvakaita seMXC-T,MXC-C15, uye MXC-37, izvo zvakagadzirirwa kugadzirwa kwema sandwich panels. Izvi zvinokonzeresa simba zvinoita basa rakakosha mukugadzirwa, zvichiita kuti furo rinoshandiswa mumapanels riwane hunhu hwaunoda, hwakadai semaumbirwo akafanana emaseru, huwandu hwakakwana hwemasero, uye kushanda zvakanaka kwekudzivirira kupisa.
Vagadziri vema sandwich panels vanogamuchirwa kubvunza nezvemhando dzakasiyana dzema catalysts edu. Nekushandisa ma catalysts edu emhando yepamusoro, unogona kuvandudza mashandiro ema sandwich panels ako, uchiita shuwa kuti anosangana nemazinga epamusoro ekushanda zvakanaka uye kugara kwenguva refu. Hunyanzvi hwedu mu polyurethane chemistry hunotibvumira kupa mhinduro dzakagadzirirwa zvinodiwa zvemaitiro ako ekugadzira, zvichikubatsira kuendesa zvigadzirwa zvepamusoro kumusika.
