Mapepala Opanda zitsulo

 Mapeto a 4 amakhalabe osankhidwa pazida zam'khitchini, malo opangira chakudya ndi zakumwa, ma elevator, ma escalator, zipatala, ndi malo aliwonse omwe zitsulo zosapanga dzimbiri zingakhudzidwe ndi chakudya. Kuzindikirika ndi zizindikiro zake zazifupi, zopukuta zowongoka, mapeto ake ndi ophweka kwambiri kuti aziwoneka bwino pakapita nthawi. Kutengera momwe chitsulocho chidzagwiritsidwire ntchito, grit yomaliza yopukutira imatha kuchoka pa 120 mpaka 320 - manambala apamwamba kwambiri amatulutsa zokanda bwino komanso mawonekedwe onyezimira pang'ono. Mosasamala kanthu za grit, zotsatira zake zimakhala pamwamba pomwe kuuma kwake sikupitilira Ra 25 µin, kupangitsa kuti ikhale yaukhondo komanso yocheperako.

Chitsulo chathu chosapanga dzimbiri cha 304-2B ndi aloyi wa carbon low, austenitic chromium-nickel alloy opangidwa kuti usachite dzimbiri komanso chitetezo champhamvu cha intergranular, ngakhale mutawotcherera kapena mankhwala ochepetsa kupsinjika. Ndi kapangidwe kamene kamapangidwira kuchepetsa kupangika kwa carbide, giredi iyi imatsimikizira kudalirika kwa njira zambiri zomangira zowotcherera ndipo ndi yoyenera kugwiritsa ntchito pomwe kutentha sikudutsa 800 ° F. M'malo mwake, pepalali silikhala la maginito ndipo silipindula ndi kuumitsa pogwiritsa ntchito zowonjezera zowonjezera kutentha, zomwe zimapangitsa kuti zikhale zolondola komanso zolimba pazogwiritsidwa ntchito zosiyanasiyana.
