Aluminium Oxide Crucible AL2O3 Crucible
soo bandhigida alaabta
Aluminium oxide crucible oo caadi ahaan loo yaqaan corundum crucible, dadku badanaa waxay ku jiraan alumina in ka badan 95% qolof ah oo loo yaqaan corundum crucible.Corundum Crucible waa iska caabin dhalaal oo xoog leh, iska caabin heerkul sare ah, caabbinta aashitada iyo alkali, caabbinta qabow iyo kulaylka, iska caabinta daxalka kiimikada.Waxay ku habboon tahay qaar ka mid ah walxaha alkaline-ka daciifka ah sida Na2CO3 anhydrous sida shaybaarada dhalaalka qulqulaya, laakiin maaha Na2O2, NaOH, iwm. Walxaha alkaline ee xooggan iyo walxaha acidic ee loo isticmaalo muunadaha dhalaalidda qulqulka ... alumina crucible oo leh 99.70% nadiif ah ayaa leh heerkul sare dahaarka iyo xoogga farsamada ee redox jawi of 1650 ℃ -1700 ℃, oo leh heerkulka ugu badan ee 1800 ℃ waqti gaaban.Marka loo eego shuruudaha codsiga, aluminium crucibles ayaa lagu heli karaa cabbirro iyo qaabab kala duwan.
Tilmaamaha ugu muhiimsan
Astaamaha ugu muhiimsan ee alumina ceramic crucible: iska caabbinta kulaylka ee ku saabsan 1200 darajo, oo ku habboon K2S207 iyo shaybaarrada kale ee walxaha aashitada ah.Guud ahaan, waa in aan loo isticmaalin dhalaalidda Na0H, Na202 iyo Na2CO3, si aan loo daxilmin kareemka dhoobada ah.Crucible Porcelain lama xiriiri karo hydrofluoric acid.
Alumina ceramic crucible waa la karkarin karaa HCl si loo hubiyo nadiifnimada walxaha iyo iska caabinta heerkulka sare.Maaddadu waxay leedahay cufnaanta sare, caabbinta oksaydhka wanaagsan, 400-500 darajo ka sarreeya walxaha garaafka, ilaa 900 darajo sare, nolol adeeg oo dheer.Iyada oo iska caabbinta kulaylka sare, isugeynta fidinta kulaylka hooseeya, kulayl wanaagsan iyo iska caabin naxdin leh iyo iska caabin daxalka wanaagsan.Waxqabadka kiimikaadku waa mid xasiloon oo asal ahaan kama falcelinayo birta dhalaalaysa, hagaajinta nadiifinta daawaha.
(1) Way fududahay in la dhaqo oo la nadiifiyo.Dhallaalka dhoobada dhoobada ah waa dhalaalaya oo jilicsan, wayna fududahay in la dhaqo ka dib isticmaalka.
(2) Stoma Porcelain aad bay u yar tahay, heerka nuugista biyuhuna aad buu u hooseeyaa.Kaydinta xalka leh maro dhoobo ah iyo xidhid adag ayaa ka hortagi kara kacsanaanta, dhex galka iyo duulaanka bakteeriyada dibadda.
(3) Degganaanshaha kiimikaad iyo adkeysiga.Qodobkani wuxuu ka sarreeyaa alaabta birta ah sida naxaasta, birta, aluminium, iwm, dhoobada dhoobada ah waxay leedahay caabin gaar ah oo ku saabsan aashitada, alkali, milixda iyo gaaska kaarboonka ee jawiga, ma fududa falcelinta kiimikada ee walxahan, ma aha miridhku. gabowga.
(4) Dejinta kulaylka wanaagsan iyo wareejinta kulaylka oo gaabis ah.Crucible Ceramic wuxuu leeyahay waxqabadka u socda heerkul gaar ah, kaas oo ka fiican kan muraayadaha, waa kaari xun oo kulaylka, wareejinta kulaylka tartiib tartiib ah, oo loo isticmaalo in lagu qabto biyo karkaraya ama xal kulul, dhamaadka ma aha mid aad u kulul.
Codsiga Alaabta
Alumina waa mid aad u ballaaran loo isticmaalo, Electronics, Batroolka, kiimikaad, refractory, dhoobada, balaastikada, dunta, waraaqaha, iyo daawooyinka iyo beeraha kale oo badan ayaa laga arki karaa sawirkeeda, guud ahaan waa sifooyinka gaarka ah ee alumina iyo aluminium hydroxide.Si kastaba ha ahaatee, in ka badan 90 boqolkiiba alumina ayaa loo isticmaalaa sida alaabta ceeriin ee aluminium electrolytic.
Waqtigan xaadirka ah, waxaa jira noocyo badan oo ka mid ah aluminium aan ahayn daawaynta, in ka badan 300 nooc, kuwaas oo mid kastaa leeyahay sifooyin jidheed iyo kiimiko oo aad u fiican, laakiin qiimihiisu aad ayuu uga sarreeyaa alumina daaweynta.
Nadiifinta sare ee ultrafine alumina, tusaale ahaan, sababtoo ah barta dhalaalka sare, qallafsanaanta sare, caabbinta sare, guryaha farsamaysan ee wanaagsan, xidhashada caabbinta, caabbinta daxalka, caabbinta kulaylka iyo Featuress kale ee 2.Main aad u fiican, sidaas darteed waxaa si ballaaran loo isticmaalaa hal qalab crystal. .
