Uphawu oluphambili
Isizathu sokuba imbiza enejacket isetyenziswe ngokubanzi ekusetyenzweni kokutya kunye neekhitshi ezinkulu zokutya ikakhulu zixhamla kwizinto ezimbini eziluncedo:
1. Imbiza enejacket ifudunyezwa ngokufanelekileyo. Ibhoyila enejacket isebenzisa umphunga woxinzelelo oluthile njengomthombo wobushushu (ukufudumeza kombane nako kungasetyenziswa), kwaye ineempawu zendawo yokufudumeza enkulu, ukusebenza kakuhle kwe-thermal, ukufudumeza okufanayo, ixesha elifutshane lokubilisa lezinto ezingamanzi, kunye nolawulo olulula lokufudumeza. ubushushu.
2. Imbiza enejacket ikhuselekile kwaye ifanelekile. Umzimba wembiza yangaphakathi (imbiza yangaphakathi) yembiza eyenziwe ngebhatyi yenziwe ngentsimbi enganyangekiyo kunye ne-asidi ye-austenitic enganyangekiyo ubushushu, ixhotyiswe ngegeyiji yoxinzelelo kunye nevalve yokhuseleko, entle ngenkangeleko, kulula ukuyifaka, kulula ukuyisebenzisa; ikhuselekile kwaye inokuthenjwa.
