Hloov Phenolic Fireproof Insulation Board yog dab tsi?

Hloov kho phenolic rwb thaiv tsev board yog ua los ntawm phenolic ua npuas ncauj.Nws cov khoom tseem ceeb yog phenol thiab formaldehyde.Phenolic ua npuas ncauj yog ib yam tshiab ntawm cov nplaim hluav taws, hluav taws kub thiab cov khoom siv hluav taws xob tsawg (hauv cov xwm txheej tsawg).Nws yog ua los ntawm phenolic resin nrog tus neeg sawv cev foaming, Kaw-cell txhav ua npuas ncauj ua los ntawm tus neeg sawv cev kho thiab lwm yam khoom ntxiv.Phenolic ua npuas ncauj yog phenolic resin raws li cov khoom siv tseem ceeb, ntxiv tus neeg sawv cev kho, tus neeg sawv cev foaming thiab lwm yam khoom siv, thaum cov resin yog sib txuas thiab ua kom ruaj khov, tus neeg sawv cev foaming generates gas dispersed nyob rau hauv nws thiab foamed ua npuas ncauj.Hloov kho phenolic fireproof rwb thaiv tsev board muaj ntau yam zoo heev:

xov xwm (2)

(1) Nws muaj cov qauv kaw-cell, qis dua thermal conductivity, thiab thermal rwb thaiv tsev ua kom sib npaug rau polyurethane, zoo dua li polystyrene ua npuas ncauj;

(2) Nyob rau hauv qhov ncaj qha ntawm cov nplaim taws, muaj cov pa roj carbon tsim, tsis muaj dej, tsis muaj curling, thiab tsis muaj melting.Tom qab cov nplaim taws kub hnyiab, ib txheej ntawm "graphite ua npuas ncauj" yog tsim rau ntawm qhov chaw, uas zoo tiv thaiv cov qauv ua npuas ncauj hauv txheej thiab tiv thaiv nplaim taws.Lub sijhawm tuaj yeem ncav cuag 1 h;

(3) Lub peev xwm ntawm daim ntawv thov yog loj, mus txog -200 ~ 200 ℃, thiab nws tuaj yeem siv tau ntev ntawm 140 ~ 160 ℃;

(4) Phenolic molecules tsuas muaj carbon, hydrogen, thiab oxygen atoms.Thaum lawv decomposed nyob rau hauv qhov kub thiab txias, tsis muaj lwm yam tshuaj lom gases tsuas yog ib tug me me ntawm CO. Qhov siab tshaj plaws pa luam yeeb ceev yog 5.0%;

(5) Ntxiv rau qhov raug corroded los ntawm muaj zog alkalis, phenolic npuas tuaj yeem tiv taus yuav luag tag nrho cov inorganic acids, organic acids, thiab organic solvents.Lub sij hawm ntev raug rau lub hnub, tsis pom kev laus tshwm sim, piv nrog rau lwm cov organic thermal rwb thaiv tsev cov ntaub ntawv, nws cov kev pab cuam lub neej ntev dua;

(6) Nws muaj cov qauv kaw zoo-cell, cov dej nqus dej tsis zoo, muaj zog tiv thaiv vapor nkag, thiab tsis muaj hws thaum lub sijhawm tso khoom txias;

(7) Qhov loj me yog qhov ruaj khov, qhov kev hloov pauv me me, thiab qhov hloov pauv loj yog tsawg dua 4% nyob rau hauv kev siv qhov kub thiab txias.

xov xwm (1)

Hloov kho phenolic hluav taws kub rwb thaiv tsev board tau dhau los ua qhov tseem ceeb ntawm nws daim ntawv thov raws li rwb thaiv tsev kub thiab nplaim hluav taws retardant cov khoom siv hauv tsev.Nws yog dav siv nyob rau hauv sab nrauv phab ntsa rwb thaiv tsev systems: nyias plastering tshuab rau sab nrauv phab ntsa, iav ntaub thaiv phab ntsa rwb thaiv tsev, zoo nkauj rwb thaiv tsev, sab nrauv phab ntsa rwb thaiv tsev thiab hluav taws rwb thaiv tsev siv, thiab lwm yam.
