Guddiga dahaarka ee loo yaqaan 'Phenolic Insulation Board' ayaa leh Qiimaynta ugu Sarreysa ee Dabka oo ka mid ah Alaabo badan oo Dahaarka dabiiciga ah

Wax qabad sare oo phenolic xumbo tamarta badbaadinaysa

Looxa xumbo phenolic wuxuu ka samaysan yahay xumbo phenolic.Maaddada xumbo phenolic waa badeeco dabiici ah oo polymer ah, kaas oo lagu xumbeeyo resin phenolic heerkulbeeye.Looxa xumbo phenolic waa dab-ilaaliye aad ugu fiican, dahaarka kulaylka, badbaadinta tamarta, quruxda iyo deegaanka saaxiibtinimo

Guddiga dahaarka ee loo yaqaan 'phenolic' ayaa leh heerka ugu sarreeya ee dabka marka loo eego alaabooyin badan oo dahaarka dabiiciga ah

Maaddada dahaarka xumbo-u-soo-saarka (board) waa balaastiig heerkulbeeg ah, waxayna leedahay iska caabbinta dabka oo go'an iyada oo aan lagu darin wax ololka celinaya.Waxay leedahay polymer bulk iyo qaab dhismeed caraf udgoon oo deggan.Marka loo eego heerka dabka ee GB8624, xumbo phenolic lafteedu waxay si fudud u gaari kartaa heerka dabka ee B1, kaas oo ku dhow A (lagu tijaabiyay GB8624-2012), waxqabadkeeda dabkuna waa B1-A.Inta u dhaxaysa labada (sida ku cad xogta la xidhiidha, Japan waxay u qoondaysay looxyada dahaarka phenolic sida "quasi aan guban" alaabta).

Sifada cajiibka ah ee walxaha dahaarka xumbo abuurka ayaa ah in iyada oo si toos ah loola xiriiro heerkulka aadka u sarreeya ee dabka furan, waxaa la sameeyay qalfoof kaarboonaysan iyo walxo gaas ah sida CO iyo CO2.Faafinta, kaarboonaysiinta kaliya ayaa ku dhacda dusha sare ee xumbo phenolic iyada oo aan la dhalaalaynin dareere, iyo looxa xumbo phenolic ayaa muujinaya caabbinta ololka ee aad u fiican.

Tilmaamaha Alaabta

Tdahaarka hermal

Xumbada phenolic waxay leedahay lebbis iyo qaab-dhismeed unug xidhan oo fiican, kulaylka kulaylkuna wuu ka hooseeyaa 0.022W/(m•K).Dejinta kulaylka wanaagsan, kala duwanaanta heerkulka hawlgalka ee ballaaran (-180 ~ +180 ℃).

Dab-demiska

Looxa xumbo xumbada ah waa mid dabka u adkaysata, ololka celisa, aan guban karin haddii uu jiro olol furan, aan qiiq lahayn, aan sun ahayn, oo aan hoos u dhicin.

Daxalka iyo iska caabinta gabowga

Heerka isbeddelka cabbirku wuxuu ka yar yahay 1%, xasilooniduna waa wanaagsan tahay.Halabuurka kiimikadu waa mid deggan, waxayna u adkaysataa daxalka xalalka organic, acids xooggan iyo saldhigyada daciifka ah, waxayna leedahay caabbinta gabowga wanaagsan.

Dahaarka cagaaran

Guddiga xumbo phenolic uma isticmaalo freon sida wakiilka xumbo ee habka wax soo saarka, kaas oo la jaan qaadaya heerarka ilaalinta deegaanka caalamiga ah, iyo qaab-dhismeedka molecular ka kooban yahay hydrogen, oxygen, iyo xubno kaarboon.Dhib la'aan, oo waafaqsan shuruudaha ilaalinta deegaanka cagaaran ee qaranka.

Acodsi

1) Xakamaynta kuleylka dibedda ee dhismaha derbiyada dibadda (nidaamka dhejiska khafiifka ah, isdhexgalka kuleylka kuleylka iyo qurxinta, nidaamka derbiga daahyada)

2) Xakamaynta hawada dhexe ee qaboojiyaha hawada isku dhafan (nooca dusha birta ah ee tuubada hawo-mareenka, laba-geesoodka aluminium foil phenolic tube hawo)

3) Beer sanduuqa birta ah ee birta ah (qolka guddiga guurguura, mashruuca nadiifinta, aqoon-is-weydaarsi nadiif ah, kaydinta qabow, qolka golaha, iwm.)

4) Dahaarka saqafka (saqafka guriga, saqafka warshadda, leben dahaarka saqafka)

5) Dahaarka dhuumaha cryogenic (tuubooyinka LNG, dhuumaha LNG, dhuumaha biyaha kulul iyo qabow)

6) Dahaarka tunnel-ka

7) Goobo kale oo kala duwan oo u baahan dahaarka kulaylka
