Ukucima umphezulu:
Ngaba umphezulu wensimbi yokufudumeza ngokukhawuleza kubushushu obukhawulezileyo ngaphezulu, kodwa ubushushu abukabinaxesha lokusasazeka phambi kokupholisa ngokukhawuleza, kwaye i-core ayinakwenzeka Inguqu yenqanaba, eqonda ukuba i-gonmen ilukhuni kunye ne-core engaguqukanga. Ifanelekile intsimbi yekhabhoni ephakathi.

⑵ Unyango lobushushu ngemichiza:
Ibhekisa kwii-atoms zekhefu zekhemikhali, kunye nobuchule bokwahluka kweatom kwiqondo lokushisa elingaphezulu, ukutshintsha ubume bemichiza, ukutshintsha ubume bemichiza kunye nokufezekisa umaleko wensimbi yentsimbi Ngeemfuno ezithile zombutho kunye nokusebenza kwenkqubo yonyango lobushushu. Ngokweentlobo zezixhobo zokufakelwa, unyango lobushushu lwekhemikhali lunokwahlulwa kuba luhlambulukuthu, lube ne-ninrication, i-cynidation kunye nomthetho wensimbi yensimbi.
I-Carburmeng: I-carburcing yinkqubo apho ii-atom zekharbon zingena kweyona ndawo yentsimbi. Kukwanokwenza i-carbon ye-carbon yensimbi enomgangatho wekhabhoni ephezulu ye-carbon, kwaye emva koko emva kokucinywa kunye nokucinywa kweqondo lokushisa eliphantsi, ukuze i-faziso ye-Worpice inobuqili kwaye inxibe inxenye yomsebenzi ubunzima kunye neplastiki yentsimbi yekhabhoni esezantsi.
I-nitrication, okanye i-nitrication, yinkqubo apho uluhlu lwentsimbi lungena kwiiathom zenitrogen. Injongo kukuphucula ubunzima kwaye unxibe ukunganyangeki komgangatho kunye nokuphucula amandla okudinwa kunye nokunganyangeki. Okwangoku, indlela yokuhlangana kwegesi isetyenziswa kwimveliso.
I-Synidation, ekwabizwa ngokuba yi-carbonitering, kukungeniswa ngaxeshanye kwi-carbon kunye nee-atom ze-nitrogen kwintsimbi. Yenza umphezulu we-calburcing yentsimbi kunye ne-nitriting.
Ukungena ngentsimbi: kubhekiswa ekungenisweni kweeatom zentsimbi kumphezulu wensimbi yentsimbi. Kukwenza ungqimba lolwabiwo lwensimbi, ukuze wenze umphezulu wentsimbi unentsimbi yentsimbi, iimpawu zentsimbi ezizodwa, ezinjengokuxhathisa ubushushu, ukunyangwa kwe-oxidation, isetyenziselwa ukuveliswa kwe I-Allining, ukungqubana, ukukoleka, isilicon njalo njalo.
