420 SS(I-Stainless Steel) i-thermal spray wire yimathiriyeli ekumgangatho ophezulu eyenzelwe izicelo zokutshiza i-arc. Eyaziwa ngokugqwesa kwayo ukumelana nomhlwa, ubulukhuni obuphezulu, kunye nokunganyangeki kakuhle, i-420 SS yintsimbi ye-martensitic enikezela ukhuseleko oluqinileyo phezu komhlaba. Olu cingo luqhele ukusetyenziswa kumashishini afana nepetrochemical, ukuveliswa kwamandla, iimoto, kunye nolwandle ukuqinisa ukuqina kunye nobomi bamacandelo abalulekileyo. I-420 SS yocingo lwe-thermal spray lufanelekile kwizicelo ezifuna i-coating eqinile, engagugiyo kunye nokumelana nokuhlwa okuphakathi.
Ukulungiswa okufanelekileyo komphezulu kubalulekile ekufumaneni iziphumo ezizezona ziphezulu ngocingo olushushu lwe-420 SS. Umphezulu oza kugqunywa kufuneka ucocwe ngokucokisekileyo ukususa izinto ezingcolisa ezifana negrisi, ioyile, ubumdaka kunye neeoksidi. I-grit blasting kunye ne-aluminium oxide okanye i-silicon carbide iyacetyiswa ukuba ifezekise uburhabaxa bomphezulu be-50-75 microns. Umphezulu ococekileyo kunye norhabaxa uphucula ukunamathela kwengubo ye-thermal spray, ekhokelela ekusebenzeni okuphuculweyo kunye nokuphila ixesha elide.

I-420 ye-SS i-thermal spray wire sisisombululo esihle kakhulu sokuphucula iipropati zomphezulu wamacandelo abonakaliswe ukuguga kunye ne-corrosion ephakathi. Ubunzima bayo obuphezulu kunye nokumelana nokunxiba kakuhle kwenza ukuba ilungele izicelo ezifuna i-coating ehlala ixesha elide kunye nexesha elide. Ngokusebenzisa i-420 SS yocingo lwe-thermal spray, amashishini anokuphucula kakhulu ubomi benkonzo kunye nokuthembeka kwezixhobo zabo kunye namacandelo.
