Njengoba isisho sisho, "izingxenye ezintathu zopende, izingxenye eziyisikhombisa zokugqoka", futhi into ebaluleke kakhulu ekugqokeni ikhwalithi yokwelashwa okungaphezulu kwezinto ezibonakalayo, ucwaningo olufanele lubonisa ukuthi ithonya lezici zekhwalithi yokumboza izinga lokwelashwa okungaphezulu kwezinto ezibonakalayo kubalwa isilinganiso sama-40-50% ngaphezulu. Indima yokwelashwa okungaphezulu ekugqokeni ingacatshangwa.
Ibanga lokwehlisa: libhekisela ekuhlanzekeni kokwelashwa okungaphezulu.

[1] I-Jet noma i-blast descaling
I-Jet noma i-blast descaling iboniswa ngohlamvu “Sa”. Kunamabanga amane okwehlisa izinga:
I-Sa1 Light Jet noma i-Blast Descaling
Ngaphandle kokukhulisa, indawo engaphezulu kufanele ingabi nawo amafutha abonakalayo kanye nokungcola, futhi ingabi nokunamathela njengesikhumba esinama-oxidized kabi, ukugqwala kanye nezingubo zopende.
I-Sa2 Thorough Jet noma i-Blast Descaling
Ngaphandle kokukhuliswa, indawo engaphezulu ngeke ingabi nagrisi ebonakalayo kanye nokungcola kanye ne-oksijini cishe ekhululekile esikhumbeni esifakwe i-oxidized, ukugqwala, okokumboza nokungcola kwangaphandle, okusele okuzonamathiselwa ngokuqinile.
I-Sa2.5 I-Jet Ephelele Kakhulu noma I-Best Descaling
Ngaphandle kokukhulisa, indawo engaphezulu kufanele ingabi nawo amafutha abonakalayo, ukungcola, i-oxidation, ukugqwala, okokunamathela nokungcola kwangaphandle, futhi imikhondo esele yanoma yikuphi ukungcola kufanele ibe namachashazi kuphela noma imithende ngokushintsha kombala okhanyayo.
I-Sa3 Jet noma ukuqhuma kwensimbi ngokubukeka okuhlanzekile
Ngaphandle kokukhulisa, indawo engaphezulu ngeke ingabi nawoyela obonakalayo, amafutha, ukungcola, isikhumba esine-oxidized, ukugqwala, okokunamathela kanye nokungcola kwangaphandle, futhi indawo engaphezulu izoba nombala wensimbi ofanayo.
[2] Ukwehliswa kwethuluzi lesandla namandla
Ukwehliswa kwethuluzi lesandla namandla kuboniswa ngohlamvu “St”. Kunezigaba ezimbili zokunciphisa:
St2 Ukwehliswa kwethuluzi eliphelele lesandla namandla
Ngaphandle kokukhuliswa, indawo engaphezulu ngeke ingabi nawoyela obonakalayo, amafutha kanye nokungcola, futhi ingabi nesikhumba esinama-oxidized kabi, ukugqwala, okokunamathela kanye nokungcola kwamanye amazwe.
I-St3 Ngokufana ne-St2 kodwa ngokuningiliziwe, ingaphezulu kufanele libe nokucwebezela kwe-metallic ye-substrate.
【3】Ukuhlanzwa komlilo
Ngaphandle kokukhulisa, indawo engaphezulu ngeke ingabi nawoyela obonakalayo, amafutha, ukungcola, isikhumba esifakwe i-oxidized, ukugqwala, okokunamathela kanye nokungcola kwangaphandle, futhi noma yimiphi iminonjana eyinsalela izoba nokuguquguquka kwendawo kuphela.
Ithebula lokuqhathanisa phakathi kwezinga lethu lokwehliswa nezinga elilinganayo lokwehlisa izinga langaphandle
Qaphela: I-Sp6 ku-SSPC iqine kancane kune-Sa2.5, i-Sp2 iwukuba ibhulashi locingo lwenziwe ngesandla futhi i-Sp3 iwukwehlisa amandla.
Amashadi okuqhathanisa ebanga lokugqwala kwendawo yensimbi kanye nebanga le-jet descaling ami kanje:
