Njengoko ilizwi lisithi, "ipeyinti ezintathu zepeyinti, iinxalenye ezisixhenxe zokugquma", kwaye eyona nto ibalulekileyo ekugqumeni umgangatho wonyango lomphezulu wezinto eziphathekayo, uphononongo olufanelekileyo lubonisa ukuba impembelelo yezinto zomgangatho wokugquma kumgangatho we unyango lomphezulu wezinto ezibalelwa kumlinganiselo we-40-50% ngaphezulu.Indima yonyango oluphezulu kwi-coating inokucingelwa.
Inqanaba lokuhla: libhekisa kucoceko lonyango olungaphezulu.

[1] Ijethi okanye iqhushumbisi ukuhla
I-Jet okanye i-blast descaling iboniswa ngonobumba "Sa".Kukho amabakala amane okuhla:
I-Sa1 Light Jet okanye i-Blast Descaling
Ngaphandle kokukhulisa, umphezulu kufuneka ungabinagrisi ebonakalayo kunye nokungcola, kwaye ungabinazinto zokuncamathelisa ezifana nesikhumba esine-oxidized kakubi, umhlwa kunye neepeyinti zepeyinti.
I-Sa2 Jet ngokucokisekileyo okanye i-Blast Descaling
Ngaphandle kokukhulisa, umphezulu uya kukhululeka kwigrisi ebonakalayo kunye nokungcola kunye ne-oksijini ekhululekile kwisikhumba esixutywe ne-oxidized, i-rust, i-coatings kunye nokungcola kwamanye amazwe, okushiyekileyo kuya kuqhotyoshelwe ngokuqinileyo.
Sa2.5 IJet eQoqoshe kakhulu okanye iBlest Descaling
Ngaphandle kokwandiswa, umphezulu kufuneka ungabinagrisi ebonakalayo, ukungcola, i-oxidation, irusi, i-coatings kunye nokungcola kwamanye amazwe, kunye neendawo ezishiyekileyo zazo naziphi na izinto ezingcolileyo kufuneka zibe namachaphaza kuphela okanye zihlulwe ngokukhanya kombala.
I-Sa3 Jet okanye i-blast descaling yentsimbi enenkangeleko ecocekileyo yomphezulu
Ngaphandle kokukhulisa, umphezulu uya kukhululeka kwi-oyile ebonakalayo, igrisi, ukungcola, ulusu oluxutywe ne-oxidized, umhlwa, iingubo kunye nokungcola kwangaphandle, kwaye umphezulu uya kuba nombala ofanayo wesinyithi.
[2] Isandla kunye nesixhobo samandla sokuhla
Ukuhla kwesixhobo sesandla kunye namandla kuboniswa ngonobumba othi "St".Kukho iindidi ezimbini zokunciphisa:
St2 Isandla esicokisekileyo kunye nesixhobo samandla sokuthoba
Ngaphandle kokukhulisa, umphezulu uya kukhululeka kwioli ebonakalayo, igrisi kunye nokungcola, kwaye ukhululekile kwisikhumba esine-oxidized, i-rust, i-coatings kunye nokungcola kwamanye amazwe.
I-St3 Ngokufanayo ne-St2 kodwa ngokucokisekileyo ngakumbi, umphezulu kufuneka ube nentsimbi ecwebezelayo ye-substrate.
【3】Ukucocwa komlilo
Ngaphandle kokwandiswa, umphezulu uya kukhululeka kwi-oyile ebonakalayo, igrisi, ukungcola, ulusu oluxutywe neoksijini, umhlwa, iingubo kunye nobumdaka bangaphandle, kwaye naziphi na iintsalela ezishiyekileyo ziya kuba ngumbala womphezulu kuphela.
Itheyibhile yokuthelekisa phakathi komgangatho wethu wokuhla kunye nomgangatho olinganayo wokuhla
Qaphela: I-Sp6 kwi-SSPC ingqongqo kancinane kune-Sa2.5, i-Sp2 i-brashi yocingo eyenziwe ngesandla kunye ne-Sp3 yokunciphisa amandla.
Iitshathi zothelekiso lwebakala lokutya komphezulu wentsimbi kunye nenqanaba lokuhla kwejethi zezi zilandelayo:
