Yakagadziriswa phenolic insulation board inogadzirwa ne phenolic foam.Zvikamu zvaro zvikuru phenol uye formaldehyde.Phenolic furo rudzi rutsva rwe-flame-retardant, fireproof uye yakaderera-utsi insulation zvinhu (pasi pemamiriro mashoma).Yakagadzirwa ne phenolic resin ine furo agent, Yakavharwa-sero rigid foam yakagadzirwa neanorapa agent uye zvimwe zvinowedzera.Phenolic foam is phenolic resin seyakanyanya mbishi zvinhu, ichiwedzera kurapa mumiriri, furo mumiriri uye zvimwe zvinhu zvinobatsira, nepo resin yakabatana-yakabatana uye yakaomeswa, iyo inopupuma inogadzira gasi rakapararira mukati mayo uye ichipupuma kuita furo.Modified phenolic fireproof insulation board ine akawanda akanakisa zvivakwa:
(1) Iine yunifomu yakavharwa-sero chimiro, yakaderera thermal conductivity, uye thermal insulation performance yakaenzana ne polyurethane, nani pane polystyrene foam;
(2) Pasi pekuita kwakananga kwemurazvo, pane kuumbwa kwekabhoni, hapana kudonha, hapana kupeta, uye hapana kunyungudika.Mushure mokunge murazvo wapisa, mutsara we "graphite foam" inoumbwa pamusoro, iyo inodzivirira zvinobudirira chimiro chefuro mumucheka uye inodzivisa kupinda kwemurazvo.Nguva inogona kusvika ku1 h;
(3) Kuwanda kwekushandiswa kwakakura, kusvika -200～200 ℃, uye inogona kushandiswa kwenguva yakareba pa140～160 ℃;
(4) Phenolic molecules ane kabhoni, haidrojeni, uye maatomu eokisijeni.Kana dzaora pakupisa kwepamusoro, hapana mamwe magasi ane chepfu kunze kwechikamu chiduku cheCO. Utsi hwehutsi hwepamusoro i5.0%;
(5) Pamusoro pekusvibiswa nemaalkali akasimba, furo rephenolic rinokwanisa kumira kunenge ese inorganic acids, organic acids, uye organic solvents.Kugara kwenguva refu kuzuva, hapana chiitiko chekuchembera chiri pachena, zvichienzaniswa nezvimwe organic thermal insulation materials, hupenyu hwayo hwesevhisi hurefu;
(6) Iine yakanaka yakavharwa-sero chimiro, yakaderera kunyura kwemvura, yakasimba anti-mhute kupinda, uye haina condensation panguva yekutonhora kuchengetedza;
(7) Saizi yakagadzikana, chiyero chekuchinja idiki, uye chiyero chekuchinja saizi iri pasi pe4% mukati meiyo tembiricha yekushandiswa.
Yakagadziridzwa phenolic fireproof insulation board yave iyo huru yekushandisa kwayo seyekudzivirira kupisa uye murazvo unodzosera zvinhu zvekuvaka.Inoshandiswa zvakanyanya mukunze kwemadziro ekudzivirira masisitimu: yakatetepa plastering masisitimu ekunze kwemadziro, girazi keteni madziro ekudzivirira, yekushongedza yekushongedza, kunze kwemadziro ekudzivirira uye mabhandi ekudzivirira moto, nezvimwe.
