Iro zita rakazara re extruded board inonzi extruded polystyrene foam board, inozivikanwawo se XPS board.Polystyrene foam yakakamurwa kuita mhando mbiri: inowedzera EPS uye inopfuurira extruded XPS.Kuenzaniswa neEPS board, XPS board ndiyo chizvarwa chechitatu cheyakaomesesa foamed insulation material.Iyo inokunda yakaoma kugadzirwa kweEPS board uye ine mashandiro epamusoro ayo EPS board isingakwanise kutsiva.Yakagadzirwa ne polystyrene resin uye zvimwe zvinowedzera kuburikidza ne extrusion process ine inoenderera uye yakafanana pamusoro pepamusoro uye yakavharwa-sero huchi chimiro.Idzi ndiro dzakakora dzakaita muzinga weuchi hadzina maburi zvachose.Rudzi urwu rweakavharika-sero chimiro Insulation zvinhu zvinogona kuve nekumanikidza kwakasiyana (150-500Kpa) uye panguva imwechete ine yakaderera yakaderera yekupisa conductivity (chete 0.028W/MK) uye inotsungirira yakanakisa kupisa kwemafuta uye kuita kwekumanikidza, uye simba rekumanikidza rinogona. kusvika 220-500Kpa.

Iyo extruded board inogadzirwa ne polystyrene resin inowedzerwa nepolymer ichipisa uye yakasanganiswa, uye iyo catalyst inoiswa jekiseni, uye ipapo iyo yakaoma foam board ine inoenderera yakavharwa-sero kupupa inoburitswa uye mukati mune yakazvimirira yakavharwa-sero chimiro.Iyo ine hushamwari hwemamiriro ekunze ekupisa kwemafuta ekudzivirira ane zvinhu zvakanakisa senge yakakwira compression kuramba, kunyura kwemvura, kunyorova, kusimba kwemhepo, huremu huremu, corrosion resistance, super anti-kuchembera (kunenge pasina kuchembera mukushandiswa kwenguva refu), uye kuderera kwemafuta conductivity. .

Extruded board inoshandiswa zvakanyanya mumadziro akaoma emadziro, flat kongiri denga uye simbi dhizaini denga rekuisa, yakadzika-tembiricha yekuchengetera pasi, nzvimbo yekupaka, airport runway, mugwagwa mukuru uye mimwe minda yekunyorova-proof insulation, kudzora pasi frost heave, ndiyo yazvino. indasitiri yekuvaka isingadhure, yemhando yepamusoro inodzivirira kupisa uye hunyoro-uchapupu zvinhu.Kuenzanisa nemamineral wool, xps board ine zvirinani kupisa conductivity kuita.Mumakore achangopfuura, xps board rave rakakurumbira zvekuvaka izvo zvine kudiwa kukuru.Kune chero kufarira, ndapota tizivise, mamwe mashoko achatumirwa kwauri
