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

Waxqabadka xumbo-badbaadinta tamarta-sare ee phenolic

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 caabin dabka oo go'an iyada oo aan lagu darin wax dib u olol ah.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 gaadhi kartaa heerka dabka ee B1, kaas oo ku dhow A (lagu tijaabiyay GB8624-2012), wax qabadkeeda dabkuna waa B1-A.Inta u dhaxaysa labada (sida laga soo xigtay 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 xiriirinayo heerkulka aadka u sarreeya ee dabka, 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 guddiga xumbo abuurka phenolic-ga ayaa muujinaya caabbinta ololka ee heer sare ah.

Tilmaamaha Alaabta

Tdahaarka hermal

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

Dab-demiska

Looxa xumbo phenolic waa mid dabka u adkaysta, ololka celisa, aan guban karin haddii uu ololka furan yahay, 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 waafaqsan heerarka caalamiga ah ee ilaalinta deegaanka, iyo qaab-dhismeedka molecular ka kooban yahay hydrogen, oxygen, iyo walxaha carbon.Dhib la'aan, si 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 mobilada, mashruuca nadiifinta, aqoon-is-weydaarsi nadiif ah, kaydinta qabow, qolka golaha, iwm.)

4) Dahaarka saqafka (saqafka la dego, saqafka warshadda, leben dahaarka saqafka)

5) Xakamaynta 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
