Wararka

Fiber refractory, oo sidoo kale loo yaqaan fiber ceramic, ayaa hadda ah shayga dib-u-celinta leh kulaylka ugu hooseeya iyo kuleylka kulaylka ugu fiican iyo saamaynta badbaadinta tamarta marka lagu daro nano-materials.Waxay leedahay faa'iidooyin badan, sida miisaanka khafiifka ah, caabbinta heerkulka sare, saameyn kuleyl ah oo wanaagsan, dhismo ku habboon, iwm. Waa qalab foorno warshadeed oo tayo sare leh.Marka la barbar dhigo lebenkii dib-u-celinta dhaqameed, kabka dib-u-celinta iyo agabyada kale, baloogyada isku laabma fiber-ka dhoobada ayaa leh faa'iidooyinka waxqabadka soo socda:

a) Miisaanka fudud (yaraynta rarka foornada iyo fidinta nolosha foornada): Fiber-ka-soo-celinta waa nooc ka mid ah walxaha dib-u-celinta faybarka.Bustaha fiber refractory inta badan la isticmaalo ayaa leh cufnaanta mugga ee 96 ~ 128kg / m3, halka cufnaanta mugga ee module fiber refractory laalaa bustaha fiber u dhexeeya 200 ~ 240kg / m3, iyo miisaanka waa 1/5 ~ 1 / 10 ka mid ah lebenka khafiifka ah ee khafiifka ah ama walxaha amorphous, iyo 1/15 ~ 1/20 ee walxaha culus.Waxaa la arki karaa in maaddada foornada fiber-ka-soo-celinta ay ogaan karto foornada kuleylka fudud iyo waxtarka sare leh, yareyneysa culeyska foornada iyo kordhinta nolosha foornada.

b) Awoodda kulaylka hooseeya (kuleylka yar ee nuugista iyo kor u kaca heerkulka degdega ah): Awoodda kulaylka ee alaabta foornada ayaa guud ahaan u dhiganta miisaanka foornada foornada.Awoodda kulaylka hooseeya macnaheedu waa in foornada ay nuugta kuleyl yar inta lagu jiro hawlgalka is-dhaafsiga, iyo xawaaraha kuleylku waa la dedejiyey.Awoodda kulaylka ee fiber-ceramic waa 1/10 oo kaliya ee dahaarka kulaylka u adkaysta iyo lebenka iftiinka iftiinka, kaas oo si weyn u yareynaya isticmaalka tamarta ee xakamaynta heerkulka foornada.Gaar ahaan foornada kuleylinta oo leh hawlgal isdhaafsi ah, waxay leedahay saameyn aad u muhiim ah oo badbaadinta tamarta ah

c) Wanaajinta kulaylka hooseeya (kulka yar ee luminta): marka celceliska heerkulka alaabta dhoobada dhoobada ah uu yahay 200C, kulaylku wuxuu ka yar yahay 0. 06W / mk, in ka yar 0 at 400 ° celcelis ahaan.10W / mk, oo ku saabsan 1/8 ee walxaha amorphous kulaylka u adkaysta, iyo ku saabsan 1/10 ee leben khafiif ah, halka conductivity kaamerada ee walxaha fiber dhoobada iyo walxaha culus ee dabka u adkaysta waa la iska indho tiri karaa.Sidaa darteed, saameynta kuleylka kuleylka ee walxaha fiber-ka-celinta ayaa aad muhiim u ah.

d) Dhisme fudud (wax balaadhin ah looma baahna): shaqaalaha dhismuhu waxay qaadan karaan jagada ka dib tababarka aasaasiga ah, iyo saamaynta qodobbada farsamada dhismaha ee saamaynta kuleylka kuleylka ee foornada foornada.

e) Codsiga ballaaran: Iyada oo horumarinta wax soo saarka iyo tignoolajiyada codsiga ee fiber refractory, alaabta fiber dhoobada refractory xaqiiqsadeen serialization iyo functionalization, iyo wax soo saarka ayaa buuxin kara shuruudaha isticmaalka ee heerkul kala duwan laga bilaabo 600 ° C ilaa 1400 ° C. Marka laga eego dhinaca morphology-ga, waxay si tartiib tartiib ah u sameysay noocyo kala duwan oo ka mid ah farsamaynta sare ama alaabada farsamaynta qoto dheer ee laga soo bilaabo suufka dhoobada dhoobada dhaqameed, bustaha fiber dhoobada, fiber-ka dareemeen alaabooyinka fiber-ka-celinta, guddiga fiber-ka dhoobada ah, alaabooyinka fiber-ka dhoobada ah, waraaqaha dhoobada dhoobada, dunta fiber-ka iyo noocyada kale.Waxay dabooli kartaa baahida foornooyinka warshadaha ee kala duwan ee warshadaha kala duwan ee alaabooyinka fiber dhoobada ah ee dib-u-celinta.

f) Caabbinta shoogga kulaylka: moduleka isku laabma fiberku wuxuu leeyahay iska caabin heer sare ah oo isbedbeddelka heerkulka daran.Marka la eego in walxaha kuleylka leh ay qaadi karaan, xuubka foornada foornada fiber-ka ayaa la kululayn karaa ama lagu qaboojin karaa xawaare kasta

o) Iska caabbinta gariir farsamo (oo leh dabacsanaan iyo dabacsanaan): bustaha fiber-ka ama bustaha fiber-ka ayaa ah mid dabacsan oo jilicsan, mana fududa in la dhaawaco.Foornada oo dhan ka dib rakibidda ma fududa in la dhaawaco marka ay saamayso ama gariirto gaadiidka wadada

h) Ma jiro foorno qalajin: iyada oo aan la helin hababka qalajinta foornada (sida daaweynta, qalajinta, dubista, habka qalajinta foornada adag iyo tallaabooyinka ilaalinta cimilada qabow), daboolka foornada ayaa la isticmaali karaa dhismaha ka dib.

1) Waxqabadka dahaarka wanaagsan ee dhawaaqa (yareeya wasakhowga sawaxanka): Xidhmada isku laabma ee fiber-ceramic waxay yarayn kartaa buuqa soo noqnoqda ee inta jeer ee ka yar 1000 Hz.Mowjadaha dhawaaqa ee inta jeer ee ka yar 300 Hz, awoodda daboolida dhawaqdu way ka sarraysaa qalabka dahsoon ee dhawaaqa caadiga ah, waxayna si weyn u yarayn kartaa wasakhowga sanqadha.

j) Awoodda xakamaynta tooska ah ee xooggan: dareenka kulaylka sare ee dahaarka dhoobada dhoobada ayaa si fiican ula qabsan kara xakamaynta tooska ah ee foornada kuleylka.

k) Degganaanshaha kiimikaad: sifooyinka kiimikaad ee xannibaadda fiber-ka dhoobada ah waa mid deggan.Marka laga reebo phosphoric acid, hydrofluoric acid iyo alkali xoog leh, asiidhyada kale, alkalis, biyaha, saliidda iyo uumiga lama baabi'in.
