Sida aynu ognahay, oo ka mid ah taarikada saxanka kuleyliyaha kuleyliyaha, saxanka titanium waa mid u gaar ah caabbinta aadka u fiican ee daxalka. Iyo xulashada gasket, viton gasket waxay caan ku tahay caabbinta aashitada iyo alkali iyo kiimikooyinka kale. Haddaba ma loo wada isticmaali karaa si loo hagaajiyo caabbinta daxalka ee saxanka kuleyliyaha?
Dhab ahaantii, saxanka Titanium iyo gaaska viton lama wada isticmaali karo. Laakiin waa maxay sababtu? Waa mabda'a iska caabinta daxalka ee saxanka titanium in labada shay aan la wada isticmaali karin, sababtoo ah saxanka titanium waa sahlan tahay in la sameeyo lakabka cufan ee titanium oxide filimka ilaalinta dusha sare, lakabkan filimka oxide si degdeg ah ayaa loo samayn karaa oxygen- ka kooban deegaan burbur ka dib. Oo tani waxay u oggolaanaysaa burburinta iyo dayactirka (dib-u-soo-celinta) filimka oksaydhka in lagu ilaaliyo xaalad xasilloon, ilaalinta walxaha titanium-ka ee gudaha ku jira burbur dheeraad ah.
Sawir daxalka ah ee caadiga ah
Si kastaba ha ahaatee, marka birta titanium ama daawaha ee deegaanka fluorine-ka kooban, hoos ficil of hydrogen ions ee biyaha, ion fluoride ka gaaska viton falcelin la titanium bir ah si ay u soo saaraan fluoride milmi, taas oo ka dhigaysa titanium godka. Isla'egta falcelintu waa sida soo socota:
Ti2O3+ 6HF = 2TiF3+ 3H2O
TiO2+ 4HF = TiF4+ 2H2O
TiO2+ 2HF = TiOF2+ H2O
Daraasaduhu waxay ogaadeen in xal acidic ah, marka fiirsashada fluoride ion gaadho 30ppm, filimka oksaydhka ee dusha titanium waa la burburin karaa, taas oo muujinaysa in xitaa haddii fiirsashada aad u yar ee fluoride ion ay si weyn u yareyn doonto iska caabinta daxalka ee taarikada titanium.
Marka birta titanium iyada oo aan la ilaalinaynin oxide titanium, jawiga daxalka leh ee ka kooban hydrogen ee horumarinta hydrogen, titanium wuxuu sii wadi doonaa inuu nuugo hydrogen, iyo falcelinta REDOX ayaa dhacda. Kadibna TiH2 ayaa laga soo saarayaa dusha sare ee titanium crystal, kaas oo dardargeliya daxalka saxanka titanium, samaynta dildilaaca oo horseedaya daadinta saxanka kulaylka.
Sidaa darteed, saxanka kuleyliyaha, saxanka titanium iyo gaasaska viton waa inaan si wadajir ah loo isticmaalin, haddii kale waxay u horseedi doontaa daxal iyo fashil ku yimaada kulaylka saxanka.
