1.Pickling tsis txaus txhais li cas?
Qhov no yog hais txog qhov seem ntawm cov hlau oxide nyob rau saum npoo ntawm steel sawb tom qab pickling. Qhov tseem ceeb, nws txhais tau hais tias lub sawb tsis raug ntxuav kom zoo; cov residue muaj cov hlau oxides thiab zoo li dub los yog tsaus nti - xim pob los yog thaj ua rau thaj.
2.Qhov xeb (corrosion) hais txog dab tsi?
Qhov no yog hais txog cov xeb txheej uas rov tshwm sim ntawm cov hlau strips tom qab pickling, vim qee qhov laj thawj. Qhov tseem ceeb, nws yog "re-corrosion," ib qho tshuaj tiv thaiv ntawm cov hlau tshiab substrate thiab ya raws, oxygen, thiab lwm yam khoom.
3.Vim li cas tsis txaus pickling ua rau "secondary corrosion"?
Lub hauv paus ntsiab lus: Ib daim ntawv hlau uas tau muab pov tseg kom zoo muaj qhov huv, greyish -dawb lossis silvery-dawb xim hlau nto, ua kom yooj yim dua tom qab passivation thiab oiling rau kev tiv thaiv xeb. Txawm li cas los xij, nyob rau hauv - cov chaw khaws cia, cov seem hlau oxide seem yog xoob thiab ntxeem tau. Thaum oiling yog thov rau kev tiv thaiv xeb, cov roj tsis tuaj yeem ua raws li qhov sib npaug thiab ruaj khov rau cov hlau oxide nplai, thiab tej zaum yuav nqus tau los ntawm nws.
Yog vim li cas: Cov cheeb tsam no poob kev tiv thaiv ntawm xeb -cov roj tiv thaiv, ua cov ntsiab lus nkag rau xeb. Thaum lub sij hawm tom ntej cia los yog kev thauj mus los, noo noo thiab oxygen yooj yim nkag mus los ntawm cov ntsiab lus tsis muaj zog, ua rau cov hlau sawb rov qab xeb dua. Hauv kev xyaum tsim khoom, qhov no rov- txheej txheej xeb tom qab pickling yog hu ua "xeb" tsis xws luag.
4.Dab tsi ua rau "indentation xeb me ntsis"?
Lub hauv paus ntsiab lus: Cov txheej txheem txias dov yuav tsum muaj siab -siab dov ntawm cov hlua hlau pickled. Yog tias qhov seem hlau oxide nplai (hauv qab -pickling) tseem nyob rau ntawm daim tawv nqaij, nws yuav raug nias rau hauv lub strip matrix nyob rau hauv rolling siab vim nws hardness, brittleness, thiab tsis zoo ductility, tsim cov pob dub los yog dub streaks.
Qhov tshwm sim: Qhov no nias - nyob rau hauv nplai ua rau kev ncaj ncees ntawm cov hlau strip nto, ua rau tsis muaj zog adhesion rau matrix thiab yooj yim detachment, tsim pits. Qhov tseem ceeb tshaj, nws ua rau cov txheej txheem tiv thaiv ntawm cov hlau ua tiav, ua rau cov cheeb tsam no muaj kev cuam tshuam rau rov qab - xeb thaum khaws cia, uas ua rau cov khoom seem.
5.Dab tsi yog kev sib raug zoo ntawm kev tsis txaus pickling thiab xeb?
Tsis txaus pickling nws tus kheej tsis sib npaug rau rusting. Nws tsuas yog txhais tau tias cov hlau oxide nplai tsis raug tshem tawm tag nrho.
Pickling tsis txaus yog qhov ua rau rusting. Nws ua rau tsis zoo ntawm cov xeb tom ntej- kev tiv thaiv kev kho mob thiab tso cai rau cov nplai kom nias rau hauv qhov chaw thaum dov, ncaj qha ua rau muaj qhov tsis xws luag ntawm cov khoom tiav tiav uas ua rau nws yooj yim rau xeb.
