[1] Dav hlau lossis Blast Descaling
Dav hlau lossis Blast Descaling yog qhia los ntawm tsab ntawv "SA". Muaj plaub qhov qib descaling:
SA1 lub teeb raj dej lossis tawg descaling
Yog tsis muaj magnification, qhov saum yuav tsum tsis muaj roj pom thiab tsis muaj adhesions xws li tawv nqaij tsis zoo, xeb thiab pleev xim.
Sa2 thurough zog los yog blast descaling
Yog tsis muaj magnification, saum npoo yuav tsum dawb los ntawm kev pom roj thiab oxygen zoo nkauj dawb los ntawm cov tawv nqaij oxidized, xeb thiab cov uas yuav tsum tau ua raws li qhov yuav tsum tau txuas.
Sa2.5 heev ti plab dav hlau lossis blast descaling
Without magnification, the surface should be free of visible grease, dirt, oxidation, rust, coatings and foreign impurities, and the residual traces of any contaminants should be only dotted or streaked with light discoloration.
Sa3 Dav Hlau lossis Blast Descaling ntawm cov hlau nrog cov npoo huv
Yog tsis muaj magnification, lub npoo yuav tsum tsis muaj roj pom, roj, pleev xim rau cov xim txawv teb chaws, thiab cov npoo yuav muaj cov tsis muaj xim hlau xim.
[2] Tes tes thiab Lub Tuam Txhab Hluav Taws Xob Descaling
Tes thiab cov cuab yeej siv hluav taws xob descaling yog qhia los ntawm tsab ntawv "St". Muaj ob chav kawm ntawm descaling:
St2 npaj tes thiab lub cuab yeej siv hluav taws xob descaling
Yog tsis muaj magnification, qhov chaw yuav tsum tsis muaj roj pom, roj thiab tsis muaj roj, thiab dawb ntawm daim tawv nqaij tsis zoo, xeb, cov tsho tiv thaiv kab mob.
St3 tib yam li ST2 tab sis ntau dua, lub saum npoo yuav tsum muaj cov xim hlau luster ntawm lub substrate.
【3】 Nplaim
Yog tsis muaj magnification, saum npoo yuav tsum tsis muaj roj pom, roj, cov tawv nqaij, xeb, thiab tej kev sib tw txawv teb chaws yuav yog qhov chaw nyob saum npoo av.
Kev sib piv cov lus ntawm peb tus qauv descaling thiab txawv teb chaws descaling qauv sib npaug
NCO TSEG: SP6 hauv SSPC yog me ntsis stricter ntau dua sa2.5, SP2 yog kev sib nyeem hlau descaling thiab sp3 yog fais fab descaling.
Sib piv cov kab kos duab ntawm cov qib npoo corrosion thiab dav hlau descaling muaj raws li hauv qab no:
