Vuto loyeretsa la zomangira zamphamvu nthawi zambiri limawonekera pambuyo pa chithandizo cha kutentha ndi kutentha, ndipo vuto lalikulu ndiloti rinsing si yoyera. Chifukwa cha kusanjika kosayenera kwa zomangira, sopo amakhalabe pamwamba, kupanga dzimbiri pamwamba ndi kuwotcha kwa alkali, kapena kusankha molakwika mafuta ozimitsa kumapangitsa kuti chomangiracho chikhale dzimbiri.
1. Kuipitsa komwe kumapangidwa potsuka
Pambuyo kuzimitsa, zomangirazo zimatsukidwa ndi silicate kuyeretsa wothandizila ndikutsuka. Zinthu zolimba zidawonekera pamwamba. Zinthuzo zidawunikidwa ndi infrared spectrometer ndikutsimikiziridwa kuti ndi inorganic silicate ndi iron oxide. Izi zimachitika chifukwa cha zotsalira za silicate pamtunda wa fastener pambuyo pakutsuka kosakwanira.
2. Kuyika kwa zomangira sikoyenera
Pambuyo kutentha fasteners kusonyeza zizindikiro za kusinthika, zilowerere ndi etha, lolani etha volatilize ndi kupeza otsala otsalira, zinthu zimenezi ndi mkulu zili lipids. Zimasonyeza kuti zomangira zimadetsedwa ndi zoyeretsa ndi kuzimitsa mafuta panthawi yotsuka, zomwe zimasungunuka kutentha kwa kutentha ndikusiya zipsera zoyaka mankhwala. Zinthu zotere zimatsimikizira kuti chomangiracho ndi choyera. Kuwunikiridwa ndi infrared spectrometer, ndi chisakanizo cha mafuta oyambira ndi ether mumafuta ozimitsa. Ether ikhoza kubwera kuchokera ku kuwonjezera kwa mafuta ozizimitsa. Zotsatira za kusanthula kwa kuzimitsa mafuta mu ng'anjo ya mauna lamba zimatsimikizira kuti zomangira zimakhala ndi makutidwe ndi okosijeni pang'ono m'mafuta ozizimitsa chifukwa chakusanjika kosayenera pakuwotcha, koma kumakhala kocheperako. Chodabwitsa ichi chikugwirizana ndi njira yoyeretsera, osati kuthetsa vuto la mafuta.
3. Zotsalira pamwamba
Zotsalira zoyera pa screw yamphamvu kwambiri zidawunikidwa ndi infrared spectrometer ndikutsimikiziridwa kuti ndi phosphide. Palibe chotsukira asidi chomwe chinagwiritsidwa ntchito kuyeretsa thanki yotsuka, ndipo kuyang'ana kwa thanki yotsukayo kunapeza kuti thankiyo inali ndi carbon solubility yambiri. Tanki iyenera kukhuthulidwa pafupipafupi, ndipo kuchuluka kwa sopo mu thanki yotsuka kuyenera kuyang'aniridwa pafupipafupi.
4. Kuwotcha kwa alkali
Mkulu mphamvu wononga kuzimitsa yotsalira kutentha blackening ali yunifolomu, yosalala mafuta wakuda pamwamba. Koma mu mphete yakunja pali malo owoneka alalanje. Kuonjezera apo, pali madera amtundu wa buluu kapena wofiira.
Zadziwika kuti malo ofiira pa screw amayambitsidwa ndi kutentha kwa alkali. Mankhwala otsuka amchere okhala ndi ma kloridi ndi ma calcium amawotcha zomangira zitsulo panthawi yotentha, ndikusiya mawanga pamwamba pa zomangira.
Pamwamba zamchere zazitsulo zomangira zitsulo sizingachotsedwe mu mafuta oziziritsa, kotero kuti pamwamba pake amawotcha pa kutentha kwakukulu kwa austenite ndikuwonjezera kuvulala mu sitepe yotsatira ya kutentha. Ndibwino kuti muzitsuka ndi kutsuka zomangira bwino musanatenthe kutentha kuti muchotse zotsalira za alkaline zomwe zimayambitsa kuyatsa kwa fasteners.
5. Kutsuka molakwika
Kwa zomangira zazikulu zazikuluzikulu, polima aqueous solution quenching nthawi zambiri amagwiritsidwa ntchito. Asanazimitse, mankhwala oyeretsa amchere amagwiritsidwa ntchito kuyeretsa ndi kutsuka zomangira. Pambuyo kuzimitsa, zomangira zachita dzimbiri mkati. Analysis ndi infuraredi spectrometers anatsimikizira kuti kuwonjezera chitsulo okusayidi, pali sodium, potaziyamu ndi sulfure, kusonyeza kuti chomangira ndi munakhala mkati mwa wothandizila zamchere kuyeretsa, mwina potaziyamu hydroxide, sodium carbonate kapena zinthu zofanana, kulimbikitsa dzimbiri. Kuchapira kwa fasteners kumayang'aniridwa ngati kuipitsidwa kwambiri ndikusinthanso madzi otsuka pafupipafupi kumalimbikitsidwanso. Kuphatikiza apo, kuwonjezera dzimbiri inhibitor m'madzi ndi njira yabwino.
