1. Waa maxay dhibic jilicsan
Meesha jilicsan ee loogu yeero quenching waa meesha jilicsan ee aan la daboolin ee qaybaha. Sidaa darteed, waxaa sidoo kale loo yaqaannaa jilicsanaanta jilicsan (softspot). Si loo yareeyo xawaaraha qaboojinta waxay la mid tahay tan deminta barta jilicsan.
Waxaa la sheegaa in xilliga roobka tubta uu u nugul yahay inuu demiyo barta jilicsan, haddii qoyaanka goobta deminta uu ka badan yahay 55%, waxay u nugul tahay inuu demiyo barta jilicsan.
Dusha sare ee qaybaha deminta ee soo noqnoqda waxay u nugul yihiin nabarrada timaha, ama cidhifka mindida Japan, midabada dhalaalaya ayaa deminaya dhibic jilicsan.
2. Sida loo helo barta jilicsan ee demaysa
Sida caadiga ah waxaa jira saddex siyaabood oo lagu helo dhibcaha jilicsan ee la demiyo. Habka ugu horreeya waa in la arko midabka iftiinka iftiinka ee dusha sare ee wax lagu shiido: habka labaad waa in habka saddexaad uu yahay in la isticmaalo daxalka acid si loo helo barta jilicsan ee deminta;taas oo ah, in lagu dhex daro qaybaha 50% hydrochloric acid xal biyaha (biyaha qoyan) ee daxalka, haddii dusha sare ee qaybtu u muuqato bar madow, barta madow waa barta jilicsan ee demaysa. Si kastaba ha ahaatee, waa in la ogaadaa in heerkulka hooseeya (180) ~ 200C) Qaybaha ayaa ku daxaloobay meesha adag, iyo midab meel aan la adkeyn. Qoto dheer ee lakabka la demiyay ayaa lagu qiyaasi karaa iyadoo la adeegsanayo habkan.
3. Sida looga hortago deminta meesha jilicsan
Si looga hortago deminta dhibcaha jilicsan, ha oksijiin ama ha saarin qaybaha marka ugu horeysa ee kululaynta.Marka labaad, si looga hortago dusha sare ee qaybaha ku xiran filimka uumiga biyaha, waxaa fiican inaad si buuxda u walaaqdo dareeraha deminta oo isticmaal buufinta biyaha qabow.Intaa dheer, haddii deminta 10% biyaha milixda ah waxay si buuxda uga hortagi kartaa deminta dhibcaha jilicsan. Intaa waxaa dheer, codsanaya lakab khafiif ah oo budada polishing dusha sare ee qaybaha deminta sidoo kale waa hab wanaagsan oo looga hortago deminta jilicsanaanta. Dhibcaha.Budada dhalaalaysa ayaa si ka dhaqso badan u qaboojisay qaybaha birta aan la daboolin oo ma damiso barta jilicsan, markaa codsanaya budada polishing ee hawlgalka mindida Japanese waa hab qarsoodi ah. Laakiin waa in la qaataa.Haddii budada dhalaalaysa ay aad u qaro weyn tahay, qaboojintu waa gaabis, ma adka.
Budada polishing waa khafiif ah oo lagu dabaqaa dusha sare ee qaybaha deminta, iyo marka la demiyo, dusha sare kuma wareegsan filimka uumiga, kaas oo noqda goobooyin yaryar oo kor u kaca si firfircoon, sidaas darteed si degdeg ah u qaboojiso.
Sida wakiilka labiska, marka lagu daro budada dhalaalaysa.Iyo dambaska kaolin iyo biyo;mica oo aan lahayn dhoobo jilicsan iyo biyo: pumice leh dhoobo jilicsan iyo biyo, kuwan ayaa la sheegay inay yihiin cuntooyin wanaagsan.
Dhowaan, xal-biyood-ku-milmi kara quenching (polimer quenching solution) ayaa si weyn loo isticmaalaa halkii saliid lagu demi lahaa, taas oo leh milmayn rogan ah oo samayn kara filim dusha sare ah marka la kululeeyo qaybaha la daweeyey.Marka heerkulku hoos u dhaco ilaa 90 ℃ (xalka qaarkood waa 74 ℃), maaskarada dusha sare waa la kala diraa marso budo dhalaalaysa}
Intaa waxaa dheer, haddii qaboojinta ultrasonic "25000 toddobaad / s", filimka uumiga ayaa sidoo kale si wax ku ool ah looga saari karaa, sidaas darteed deminta dhibcaha jilicsan ayaa sidoo kale laga hortagi karaa. Qaboojinta Ultrasonic waa hab qaboojin cusub.
