Nthawi zina timapeza kuti zomangira zomwe zimayikidwa pamakina ndi dzimbiri kapena zakuda. Kuti zisakhudze kugwiritsa ntchito makina, momwe mungayeretsere zomangira zakhala nkhani yofunika kwambiri. Chitetezo chogwira ntchito cha zomangira sichimasiyanitsidwa ndi zoyeretsa. Pokhapokha poyeretsa ndi kukonza zomangira nthawi zonse ndizotheka kuti gawo la zomangira lizitha kuseweredwa bwino. Chifukwa chake lero ndikuwonetsa zoyeretsera zomwe zimagwiritsidwa ntchito kwambiri.

1. Suluble emulsified kuyeretsa wothandizila.

Ma emulsifiers osungunuka amakhala ndi ma emulsifiers, dothi, zosungunulira, zoyeretsera, zoletsa corrosion, ndi madzi pang'ono. Ntchito yamadzi ndiyo kusungunula emulsifier, yomwe imasungunula dothi pamwamba pa chomangira, ndipo nthawi yomweyo imasiya filimu yotsutsa dzimbiri pamwamba pa chomangira. Emulsified detergent ndi chinthu chokhazikika chamafuta chomwe chimasanduka emulsion yoyera ikasungunuka m'madzi. Emulsifiers ndi zotsukira zimagwira tinthu ting'onoting'ono ndikusungunula kukhala zotsukira zomwe zimakhala ndi zosungunulira ndi mafuta.

2. Alkaline kuyeretsa wothandizira.

Zotsukira zamchere zimakhala ndi zotsukira ndi zamchere zamchere zamchere zamchere za surfactants. Phindu la pH la wothandizira kuyeretsa liyenera kukhala lozungulira 7. Zosakaniza zoyeretsera za mtundu uwu wa kuyeretsa ndi ma hydroxides, carbonates, phosphates, etc. Zomwe zili pamwambazi zamchere zosiyanasiyana ndi zowonjezera zimakhala zoyeretsera komanso zimakhala zotsika mtengo.
