Iarhente yokunyanga umphezulu ibhekisa kwi-reagent esetyenziselwa ukunyanga umphezulu wento ukuze kufezekiswe injongo ethile, kubandakanya iarhente yokunyanga umphezulu wesinyithi, iarhente yokunyanga umphezulu we-polytetrafluoroethylene kunye nearhente yokunyanga umphezulu we-silica gel.

Iarhente yonyango lomphezulu wesinyithi ibhekisa kumphezulu wesinyithi wonyango olwahlukeneyo lweearhente zeekhemikhali zegama eliqhelekileyo. Unyango lomphezulu wesinyithi oluquka ukususa amafutha, ukususa umhlwa, ukuphosphata, ukuthintela umhlwa kunye nolunye unyango lwangaphambi kwesiseko, yenzelwe iteknoloji yokugquma isinyithi, iteknoloji yokukhusela isinyithi ukulungiselela, umgangatho wonyango lwangaphambi kwesiseko unempembelelo enkulu ekulungiseleleni ukugquma okulandelayo kunye nokusetyenziswa kwesinyithi.

Umzekelo, i-BM-QY510 luhlobo lwe-fluid low foam, ayina-phosphorus kwaye i-degreaser enamandla enobuhlobo nokusingqongileyo. Ingasusa i-oyile enzulu, i-polish kunye nolwelo olusebenzayo lwesinyithi kumphezulu wentsimbi, intsimbi kunye nentsimbi engatyiwayo ngokusebenzisa ishawa esemgangathweni okanye i-flood stain.
