Imibhobho kufuneka isetyenziswe ukubonelela ngemichiza efunekayo kwisixhobo sokuvelisa. Ukugcinwa kweekhemikhali kunye namagumbi okuhambisa ngaphakathi kwegumbi elicocekileyo ngokuqhelekileyo abekwe kwindawo yokuncedisa imveliso, ngokuqhelekileyo kumgangatho ophantsi wesakhiwo esisodwa okanye isakhiwo esinemigangatho emininzi, kufuphi nodonga lwangaphandle. Amachiza kufuneka agcinwe ngokwahlukeneyo ngokweempawu zawo zomzimba kunye neekhemikhali. Iikhemikhali ezingahambelaniyo kufuneka zibekwe kumagumbi ahlukeneyo okugcina iikhemikhali kunye namagumbi okuhambisa, ahlulwe ngezahlulo eziqinileyo. Iikhemikhali ezinobungozi kufuneka zigcinwe kwindawo ehlukeneyo yokugcina okanye amagumbi okuhambisa kunye nenqanaba lokumelana nomlilo ubuncinane kwiiyure ezingama-2.0 phakathi kwamagumbi akufutshane. La magumbi kufuneka abekwe kwigumbi elikumgangatho wokuqala wesakhiwo semveliso, kufutshane nodonga lwangaphandle.
2. Amagumbi acocekileyo kumashishini e-electronics ahlala anamagumbi okugcina kunye nokusabalalisa i-acids kunye ne-alkalis, kunye ne-solvents ezinokutsha. Ukugcinwa kwe-Acid kunye namagumbi okuhambisa ngokuqhelekileyo ukugcinwa kwendlu kunye neenkqubo zokuhambisa i-sulfuric acid, i-phosphoric acid, i-hydrofluoric acid, kunye ne-hydrochloric acid. Ukugcinwa kwealkali kunye namagumbi okuhambisa ngokuqhelekileyo izindlu zokugcina kunye nokusabalalisa iinkqubo ze-sodium hydroxide, ikhekhe le-hydroxide, i-ammonium hydroxide, kunye ne-tetramethylammonium hydroxide. Ukugcinwa kwe-solvent enokutsha kunye namagumbi okuhambisa ngokuqhelekileyo ukugcinwa kwendlu kunye neenkqubo zokusasazwa kwezinto eziphilayo ezifana ne-isopropyl alcohol (IPA). Amagumbi acocekileyo kwizityalo zokwenza i-wafer yesekethe ezidibeneyo nazo zinendawo yokugcina i-slurry kunye namagumbi okuhambisa. Ukugcinwa kweekhemikhali kunye namagumbi okuhambisa ngokuqhelekileyo abekwe kwiindawo ezincedisayo zokuvelisa okanye ezixhasayo kufuphi okanye kufuphi neendawo zokuvelisa ezicocekileyo, ngokuqhelekileyo kumgangatho wokuqala kunye nokufikelela ngokuthe ngqo ngaphandle.
3. Amagumbi okugcinwa kweekhemikhali kunye nokuhanjiswa kweekhemikhali axhotyiswe ngemigqomo yokugcina okanye iitanki zamandla ahlukeneyo ngokusekelwe kuhlobo, ubuninzi, kunye neempawu zokusetyenziswa kweekhemikhali ezifunekayo kwimveliso yemveliso. Ngokwemigangatho kunye nemimiselo, iikhemikhali kufuneka zigcinwe ngokwahlukeneyo kwaye zihlelwe. Umthamo wemigqomo okanye iitanki ezisetyenzisiweyo kufuneka zanele iintsuku ezisixhenxe zokusetyenziswa kwemichiza. Imigqomo yemihla ngemihla okanye iitanki kufuneka zibonelelwe, kunye nomthamo owaneleyo wokugubungela ukusetyenziswa kweeyure ezingama-24 zeekhemikhali ezifunekayo kwimveliso yemveliso. Amagumbi okugcina kunye nokusabalalisa i-solvents ezinokutsha kunye neekhemikhali ze-oxidizing kufuneka zihlulwe kwaye zihlulwe kumagumbi akufutshane kunye neendonga eziqinileyo ezinokumelana nomlilo kunye nesantya sokumelana nomlilo kwiiyure ze-3.0. Ukuba zibekwe kumgangatho wokuqala wesakhiwo esinemigangatho emininzi, kufuneka zihlulwe kwezinye iindawo ngemigangatho engenakutsha kunye nenqanaba lokumelana nomlilo ubuncinane iiyure eziyi-1.5. Igumbi eliphakathi lolawulo lokhuseleko lweekhemikhali kunye nenkqubo yokubeka iliso ngaphakathi kwegumbi elicocekileyo kufuneka libekwe kwigumbi elahlukileyo.
4. Ubude bokugcinwa kweekhemikhali kunye namagumbi okuhambisa iikhemikhali ngaphakathi kwegumbi elicocekileyo kufuneka bumiselwe ngokususela kwiimfuno zezixhobo kunye neemfuneko zoyilo lwemibhobho kwaye ngokubanzi abufanele ukuba ngaphantsi kwe-4.5 yeemitha. Ukuba ibekwe ngaphakathi kwendawo yokuncedisa imveliso yegumbi elicocekileyo, ukuphakama kwendawo yokugcina imichiza kunye negumbi lokuhambisa kufuneka lihambelane nokuphakama kwesakhiwo.
