Cov Khoom Txhais: Cov ntsiab lus txoj haujlwm ntawm cov huab cua tshiab sib xyaw
Puas yog cov khoom siv cua sib xyaw ua ke cov khoom lag luam raws cov phenolic npuas cov ntaub ntawv rwb thaiv tsev. Lawv noj cov phenol ua npuas dej raws li cov txheej txheem tseem ceeb ntawm cov txheej txheem (xws li cov ntaub ntawv xim siab, cov ntaub nplaum txhuas, thiab lwm yam.
Lawv feem ntau yog siv rau cov tsheb thauj cua hauv kev ua pa thiab tshuab cua txias, hloov cov roj cua galvanized, hloov cov khoom siv cua sov xws li kev tiv thaiv cua sov, kev tiv thaiv hluav taws thiab kev tiv thaiv hluav taws.
Cov qauv tseem ceeb: peb {- txheej txheej ua tau zoo lav
Tub ntxhais txheej:
Phenolic ua npuas dej, nrog cov thermal conductivity ntawm tsawg dua los yog sib npaug rau 0.025w / (hauv 25%, muaj ob qho tib si thermal rwb thaiv tsev thiab muaj qee yam lub zog muaj zog.
Sab hauv txheej thiab txheej sab nraud:
Sab hauv txheej: feem ntau ua los ntawm txhuas ntawv ci lossis cov pa fiberglass, nws yog cov huab cua tsis zoo, txo cov hws khov kho ntawm phab ntsa sab hauv ntawm tib lub sijhawm.
Txheej sab nraud:Xaiv cov xim steel phaj (rau sab hauv tsev qhuav ib puag ncig) lossis galvanized aluminium phaj (ib puag ncig magnesium) raws li qhov chaw. Nws yog qhov cuam tshuam - tiv taus thiab corrosion {{{}} tiv taus cov qauv txheej txheem tag nrho ntawm cov huab cua.
Cim npe nrov: Phenolaum Ua npuas ncauj Fludich Ciav, Tuam Tshoj, cov chaw muag khoom, chaw tsim khoom, Hoobkas, Mekas
