Pali mitundu yosiyanasiyana ya makina opangira bulichi omwe alipo opangira bulichi wa nsalu omwe amatha kupanga ma bleaching agents monga sodium hypochlorite. Nazi zina zomwe mungachite: 1. Makina a electrolysis: Makinawa amagwiritsa ntchito mchere, madzi ndi magetsi kuti apange sodium hypochlorite. Njira ya electrolysis imalekanitsa mchere kukhala sodium ndi chloride ayoni, ndipo mpweya wa chlorine umasakanizidwa ndi madzi kupanga sodium hypochlorite. 2. Gulu riyakitala: Mtanda riyakitala ndi chidebe kusakaniza sodium hydroxide, klorini ndi madzi kupanga sodium hypochlorite. Zimene ikuchitika mu anachita chotengera ndi kusanganikirana ndi oyambitsa dongosolo. 3. Kupitilira riyakitala: The riyakitala mosalekeza ndi ofanana ndi mtanda riyakitala, koma amathamanga mosalekeza ndi kumapanga otaya nthawi zonse sodium hypochlorite. 4. Njira Zopha tizilombo toyambitsa matenda: Makina ena amagwiritsa ntchito nyale za ultraviolet (UV) kupanga bulitchi poyeretsa nsalu. Kuwala kwa UV kumachita ndi mankhwala kuti apange mankhwala ophera tizilombo amphamvu ndi ma bleach. Posankha makina opangira ma bleach, ndikofunikira kuganizira mphamvu ya makinawo, mawonekedwe ake otetezeka, kusavuta kugwiritsa ntchito ndi kukonza, komanso mtengo wake. M'pofunikanso kutsatira malangizo a chitetezo ndi kusamalira bleach mosamala kupewa ngozi ndi kusunga otetezeka.
