Labadii sano ee la soo dhaafay, oo ay horseedday horumarka tignoolajiyada ee agabka ilaalinta kulaylka ee baytariyada tamarta cusub, macaamiishu waxay si isa soo taraysa u dalbadaan waxqabadka dahaadhka kulaylka ee la xoojiyay oo ay weheliso iska caabbinta dhoobada u eg-hanti fure u ah u adkaysiga saamaynta ololka.
Tusaale ahaan, codsiyada qaarkood waxay u baahan yihiin heerkul-kuleyl ololka dhinaca hore ah oo ah 1200 ° C iyadoo la ilaalinayo heerkulka dhinaca dambe ee ka hooseeya 300 ° C. Agabka hawada hawada, dabka ololka dhinaca hore ee acetylene at 3000°C wuxuu u baahan yahay kulayl dhinaca dambe ka hooseeya 150°C. Gaar ahaan dhibka leh ayaa ah baahida kor u kaca ee waxqabadka isku-buufinta ee xumbo silikoon dhoobada ah, taas oo u baahan labadaba isku xidhka hoose iyo ilaalinta kuleylka heerkul sare. Agabkani waxa ay si wada jir ah u soo bandhigayaan baahida dahaarka kulaylka cusub ee tignoolajiyada dhoobada.
Shuruudaha waxqabadka gaarka ah (Tixraac kaliya):
Kuleyli muunadda dusheeda meel kuleylinta sida hoos ka muuqata. Ku ilaali dusha kulul 600 ± 25 °C 10 daqiiqo. Codso cadaadis ah 0.8±0.05 MPa heerkulka tijaabada, hubinta in heerkulka dusha sare uu ka hooseeyo 200°C.
Maanta, waxaan qodobadan ku soo koobeynaa tixraacaada.
1. Silicate Calcium Synthetic - Dahaarka kulaylka ee Filler cad
Silicate calcium synthetic waxa uu u jiraa laba nooc: qaab-dhismeedyo dalool/spherical ah iyo qaab-dhismeedyo faybar-u eg oo dhoobada ah. In kasta oo ay kala duwan yihiin qaab-dhismeedka iyo qaab-dhismeedka, labaduba waxay u adeegaan sidii heerkul sare oo heerkul sare ah oo u adkaysta buuxinta cad ee buuxinta.
Fiber silicate calcium synthetic waa bey'ada saaxiibtinimo iyoWalxaha dahaarka kulaylka ammaan ahoo leh iska caabin heerkul sare ah ilaa 1200-1260 ° C. Silicate fiber calcium silicate fiber synthetic synthetic oo si gaar ah loo farsameeyay waxay u adeegi kartaa sida walaxda lagu xoojiyay fiber-ka ee dahaarka heerkulka sare.
Silicate kalsiyum-dabool leh ama wareegsan, ayaa dhanka kale, ka muuqda cadaan sare, fududaynta isku-darka, qaab-dhismeedka nanoporous-ka hodanka ah, qiimaha nuugista saliidda aadka u sarreeya (ilaa 400 ama ka sarreeya), iyo xorriyadda kubbadaha slag ama qaybo waaweyn. Waxay cadaysay codsiyada ku jira dahaarka u adkaysta heerkulka sare iyo baalasha dabka, taas oo muujinaysa suurtogalnimada in lagu daro walxaha u adkaysta dhoobada si loo bixiyo dahaarka heerkulka sare.
Codsiyada kale waxaa ka mid ah: wax lagu daro dareeraha budada ah, daahan budo ah oo heerkul sare leh, xajiyayaal cadar ah, wakiilada faleebada ka hortagga, qalabka jajabinta biriiga, caag silikoon ah oo cadaadis hooseeya iyo saliid silikoon ah oo is-burburisa, buuxinta waraaqaha, iwm.
2. Magnesium Aluminium Silicate oo dabada leh- Xakamaynta kulaylka & Cadaadiska Heerkulka Sare
Macdanta silicate waxay u baahan tahay caleenta heerkulka sare leh oo leh dib-u-celin ilaa 1200 ° C. Asal ahaan ka kooban silicate aluminium magnesium, waxay leedahay qaab dhismeed lakabyo qani ah oo bixiya awood isku xidhid sare, iska caabin biyo aad u wanaagsan, muddo dheer oo diidmo ah, iyo kharash-oolnimo sare.
Shaqadeeda aasaasiga ah waxaa ka mid ah dahaarka heerkulka sare, dhimista cufnaanta, dib-u-soo-celinta la xoojiyey, iyo hagaajinta caabbinta caabbinta iyo kuleylka kulaylka lakabyada kaarboonka iyo daasadaha. Codsiyada waxaa ka mid ah walxaha dahaarka dhoobada ah, dahaarka dabka-celiska ah ee qaaliga ah, alaabada dahaadhka celinaya, iyo agabka dahaadhka kulaylka u adkaysta.
3. Microspheres dhoobada - Iska caabin heerkul sare ah, kulaylka kuleylka, xoogga cadaadiska
Microspheres galaas madhan ayaa shaki la'aan ah qalab dahaarka kulaylka ah oo aad u fiican, laakiin iska caabintooda heerkulku kuma filna. Dhibcahooda jilicsan waxay guud ahaan u dhexeeyaan 650-800 ° C, kulaylka dhalaaliduna waa 1200-1300 ° C. Tani waxay xaddidaysaa codsigooda xaaladaha kuleylka kuleylka hooseeya. Marka la eego xaaladaha heerkulka sare sida dhoobada iyo iska caabbinta, waxay noqdaan kuwo aan waxtar lahayn.
Microspheres dhoobada bannaan ayaa xalliya arrintan. Asal ahaan ka kooban aluminosilicate, waxay bixiyaan iska caabin heerkul sare ah, dahaarka kulaylka heer sare ah, refractory sare, iyo iska caabin sare jaban. Codsiyada waxaa ka mid ah waxyaabaha lagu daro dhoobada silikoonka, agabka dahaarka refractory, wax lagu daro kulaylka sare ee xabagta organic, iyo caag adkeysi heerkul sare leh. Qaybaha muhiimka ah waxay ka kooban yihiin hawada sare, sahaminta badda moolka dheer, agabka isku dhafan, dahaarka, dahaarka diida, warshadaha batroolka, iyo agabka dahaarka.
Kani waa budo spherical godan kulaylka u adkaysta oo aad u fudud in lagu daro (ka duwan mikrospheres galaas godan, kuwaas oo u baahan hore u firdhiso ama wax ka beddelka loogu daro habboon) oo muujiya iska caabin dildilaaca aad u fiican. Sifadeeda lagu garto ayaa ah in ay tahay shay dusha sare ka furan oo aan ku sabbayn biyaha dushooda, taas oo ka dhigaysa mid fudud in la dhumucdo oo la dejiyo.
Intaa waxaa dheer, hadal kooban oo ku saabsanbudada airgel- walxo dahaadhida silica dalool ee synthetic. Airgel waxaa si weyn loogu aqoonsaday inuu yahay dahaye heerkulbeeg ah oo aad u wanaagsan, oo laga heli karo noocyada hydrophobic/hydrophilic. Tani waxay u ogolaanaysaa xulashada hababka daawaynta ku haboon ee ku salaysan resin substrates, wax ka qabashada caqabadaha budada airgel ee kala firdhiso aadka u-fudud iyo hagaajinta kala firdhiso. Xirmooyinka hawada-ku-saleysan ee biyaha ayaa sidoo kale diyaar u ah in si habboon loogu daro nidaamyada aqueous.
Qalabka dahaarka kulaylka ee gaarka ah ee budada airgel waxay awood u siineysaa codsigeeda: - Caagadaha wax lagu daro ee caagga ah - Qalabka kuleylka kulaylka ee baytariyada tamarta cusub - Dhisidda dahaarka dahaarka - Fiilooyinka kuleylka kuleylka - Dhismayaasha daahyada kuleylka - Daboolka kuleylka kuleylka - Xabagta kuleylka kuleylka.
