Phenolic ua npuas ncauj khoom yog cov khoom siv hluav taws xob hluav taws xob, uas muaj qhov zoo ntawm polyvinyl chloride, polystyrene thiab polyurethane ua npuas ncauj plastics.also muaj tsis muaj freon, zoo corrosion kuj, thermal conductivity, kub kub scope (60 ~ 150 ℃), waterproof thiab cov laus kuj muaj zog; kev tsim vaj tse, zoo nkauj zoo nkauj, tshwj xeeb tshaj yog muaj kev tiv thaiv kev tiv thaiv hluav taws zoo, nws muab qhov chaw dav dav.
Rigid phenolic ua npuas ncauj kev tsav nkoj xaiv lub ntsiab tswj tsis tau ntawm qhov ceev, thermal conductivity, combustion kev ua tau zoo, cov thickness ntawm yeeb nkab riam phom thiab kev yoojyim kev tiv thaiv, kev sib tsoo kom ua kom sib txawv, kev kub ntawm qhov ntswg, qhov dej ntawm qhov dej, thiab lwm yam.
(1) Cov ntaub ntawv ntawm thermal insulation txheej yuav tsum xaiv cov khoom uas yuav muab tau daim ntawv pov thawj ntawm kev tso cai ntawm kev tso cai, thermal conductivity, bulk density, mechanical light and non-combustible, inflammable and combustible properties; cov ntaub ntawv, kev nqus dej, kev hygroscopicity thiab daim ntawv pov thawj hydrophobicity ntawv pov thawj feem ntau yuav tsum tau siv rau cov ntaub ntawv pov thawj cov ntaub ntawv pov thawj, nws yog qhov tsim nyog los muab cov ntaub ntawv nthuav tawm los yog thim tam sim no.
(2) Kev sib tiv tauj ntawm cov yeeb nkab tsis muaj hlau thiab cov yeeb nkab ntawm cov hlau, cov txheej txheem kub-resistant txheej yuav tsum tau muab daim ntawv pov thawj tias cov ntaub ntawv saum toj no yuav tsis ua kom tawg taus.
Daim ntawv tso cai tua hluav taws xob yuav tsum ua raws li cov hauv qab no:
Los ntawm cua sov ntawm cov khoom siv thiab cov yeeb nkab tawm sab nraud ntawm qhov kub thiab txias>> 100 ℃, cov khoom siv thermal barrier yuav tsum tau siv raws li cov chav kawm ntawm cov khoom ua haujlwm tsis kub hnyiab.Yaub thaiv cov thermal ntawm cov khoom siv thiab cov yeeb nkab ntawm qhov kub txog 100 ℃ , thermal barrier khoom yuav tsum tsis muaj tsawg tshaj li qhov yuav tsum tau ua rau cov khoom siv hluav taws kub ntawm cov khoom siv sab nraud los ntawm cov khoom siv hluav taws xob los ntawm cov khoom siv hluav taws xob thiab cov yeeb nkab rau sab nraud 50 ℃ los yog tsawg, combustible b2 cov ntaub ntawv kawm ua haujlwm.
(3) Yuav tsum siv cov khoom thaiv nyhav tsis zoo rau cov thermal insulation thiab condensation ntawm cov yas kav dej. Cov kev sib nraus ntawm cov kev txhawb zog ntawm cov yeeb nkab yas yuav tsum tsis pub ntau tshaj qhov uas yuav tsum tau ua nyob rau hauv lub teb chaws tus qauv dej khoom thiab kua, kev tsim cov dej thiab cov yeeb nkab yeeb nkab 02ss405-1 ~ 4.
(4) Cov kav hlau thiab cov kav dej hauv thermal insulation engineering, lub thickness ntawm daim phuam rwb yog loj, lub yeeb nkab kab, qhov kub thiab txias nruab nrab ntawm tib lub sijhawm, lub thermal barrier thickness ntawm cov hlau dua cov yeeb nkab yas thermal thaiv thickness ntawm loj heev, tshwj xeeb tshaj yog lub cev loj (yas hlau phab ntsa yog tuab), nws qhov txawv qhov txawv yog qhov loj dua.lawv yuav tsum tau cais cais.
Thaum tshav kub kub txuag hluav taws kub ntawm lub tshav kub kub
(1) Thaum cov hlau thiab fiberglass daim ntawv tiv thaiv cov yeeb nkab thaiv cov hluav taws xob thaiv: Nws yog ib qho tsim nyog siv cov nplaum rau ntawm cov pob qij txha fiberglass daim ntawv txheej txheem.
(2) Thaum lub qhov cub tawg ntawm lub qhov rai thaiv cov cav ntoo thaiv tsev: Saib cov qauv txheem, 03 s401 ≤ rwb thaiv tsev hom, Ⅱ hom tsim rau sab hauv tsev ntau tshaj qhov qub. Feem ntau, Ⅳ siv ua chaw thiab chaw ua kom zoo.
(3) vias cua ntsaws thaiv txoj hlua: Cov yeeb nkab thaiv ntsug hlau, txoj hlua hlau thaiv cov hlua, tiam sis lub vaj huam sib luag saum toj kawg nkaus yuav tsum yog 5% txoj kab nqes, muaj ze ntawm daim npog hlau thiab daim npog ob sab sib npaug.
(4) Cov hluav taws xob tiv thaiv ntawm peb lub tsho sov: Lub tshav kub ntawm lub luj tshib thiab cov txheej hlau thaiv los ntawm cov hlau lossis fiberglass yuav tsum raug tsim ua hauv seem raws li qhov loj ntawm txoj hlua ntawm lub luj tshib ntawm lub luj tshib. cov pob qij txha yuav tsum raug kaw, tawm hauv cov xim tsis muaj hluav taws xob-uas muaj hluav taws-resistant yuav tsum siv rau txheej txheej ntawm daim iav.
(5) Tus qauv flange thiab lub rwb thaiv tsev: Lub nruas qhov tseem ceeb yog tib yam li ntawm cov yeeb nkab txuas.when qhov ruaj flange thiab valve rwb thaiv tsev siv nyob rau hauv lub trench, nws cov txheej txheem tiv thaiv yuav tsum yog tib yam li ntawm cov hlua hluav taws xob tiv thaiv txheej .
