Rigid polyurethane foam, inonzi rigid polyurethane foam, yechipiri chete kune inoshanduka polyurethane furo muhuwandu hwezvigadzirwa zve polyurethane.
Polyurethane rigid foams anonyanya kuvharwa-sero chimiro, ane yakanaka yekupisa yekumisa mhedzisiro, huremu huremu, yakakwira chaiyo simba, kuvakwa kuri nyore uye humwe hunhu hwakanaka.
Panguva imwecheteyo, ivo vanewo hunhu hwekuvharira ruzha, kushomeka kwekudzivirira, kuvharwa kwemagetsi, kupisa kupisa, kutonhora kupikisa, kupikisa kunyungudika, nezvimwewo, uye anoshandiswa zvakanyanya Insulating zvinhu zvefiriji nemafiriza, kuchengetera kutonhora, marori efiriji, zvivakwa. , matangi ekuchengetera, uye mapaipi anoshandiswa muzviitiko zvisiri zvekudzivirira, senge kutevedzera huni, kurongedza zvinhu, nezvimwe.
Kazhinji kutaura, rigid polyurethane foam ine density yakaderera inonyanya kushandiswa sekudzivirira kupisa (kuchengetedza kupisa) zvinhu, uye yakasimba polyurethane foam ine density yakakwirira inogona kushandiswa seyakaumbwa zvinhu (kutevedzera huni).
Rigid polyurethane foam inowanzoputirwa nekamuri tembiricha, uye maitiro ekuumba ari nyore.Zvinoenderana nedhigirii rekuvaka mechanisa, inogona kupatsanurwa kuita furo remanyorero uye mechaniki foaming;maererano nekumanikidzwa panguva yekupupa, inogona kukamurwa kuva yakakwirira-kumanikidza kupupa uye kuderera-kupupuma furo;maererano nenzira yekuumba, inogona kukamurwa kuita kudurura furo nekupfapfaidza ichipupuma.
Iko kushandiswa kukuru kwe polyurethane rigid foam ndeiyi inotevera:
1. Zvishandiso zvekutonhodza nefiriji muzvikafu nemamwe maindasitiri: semafiriji, mafiriza, chengetedzo inotonhora, marori efiriji, nezvimwewo, polyurethane rigid foam ndiyo yakanyanya kunaka yekuvharisa midziyo yekuomesa nechando.
2. Insulation yezvigadzirwa zvemaindasitiri: senge matangi ekuchengetedza, mapaipi, nezvimwe.
3. Zvishandiso zvekuvakisa: Munyika dzakabudirira muEurope neAmerica, foam yakaoma yepolyurethane yekuvaka inotora inenge hafu yehuwandu hwekushandiswa kwefuro rakaomarara, iro rinopfuura kamwechete kuwanda kwefuro rakaomarara remafiriji nemafiriza;muChina, furo rakaomarara rinoshandiswa muindasitiri yekuvaka.Iko kushandiswa hakuna kupararira semunyika dzekuMadokero dzakabudirira, saka mukana webudiriro wakakura kwazvo.
4. Indasitiri yekufambisa: sematenga emotokari, zvikamu zvemukati, nezvimwe.
5. Kutevedzera huni: high-density (density 300 ^ 700kg/m3) polyurethane rigid furo kana girazi faibha yakasimbiswa rigid furo ipurasitiki yefuro yechimiro, inozivikanwawo sehuni yekutevedzera, ine simba rakakwirira, kusimba kwakanaka, dense uye yakaoma goko, simple molding process, Iine hunhu hwemhando yepamusoro yekugadzira, simba repamusoro kupfuura huni hwechisikigo, uye kuderera kwehuni pane huni chaihwo.Inogona kutsiva huni kune zvakasiyana-siyana zvigadzirwa zvepamusoro.
6. Potting zvinhu, nezvimwewo.
Chero polyurethane yakaoma furo zvigadzirwa zvaunoda kugadzira, unogamuchirwa kutibvunza, tinogona kupa yakanakisa purojekiti mhinduro.
