I-ejenti yokwelapha engaphezulu ibhekisela kwinto esetshenziswayo ukwelapha ingaphezulu lento ukuze kufezwe injongo ethile, okuhlanganisa i-ejenti elaphayo engaphezulu, i-polytetrafluoroethylene elapha ubuso kanye ne-ejenti yokwelapha ye-silica gel.

I-Metal surface treatment ejenti ibhekisela endaweni yensimbi yokwelashwa okuhlukahlukene kwamakhemikhali egama elijwayelekile. Ukwelashwa kwe-Metal surface kufaka phakathi ukuwohloka, ukususwa kokugqwala, i-phosphating, ukuvimbela ukugqwala nokunye ukwelashwa kwangaphambi kwesisekelo, okobuchwepheshe bokumboza insimbi, ubuchwepheshe bokuvikela insimbi ukulungisa, ikhwalithi yokwelashwa kwangaphambi kwesisekelo kunethonya elikhulu ekulungiseleleni okunamathelayo okulandelayo futhi ukusetshenziswa kwensimbi.

Isibonelo, i-BM-QY510 iwuhlobo loketshezi olunamagwebu oluphansi, olungenayo i-phosphorus kanye ne-degreaser eqinile evumelana nemvelo. Ingasusa uwoyela, upholishi kanye noketshezi olusebenzayo lwensimbi ebusweni bensimbi, insimbi nensimbi engagqwali ngokusebenzisa ishawa yekhwalithi noma ibala lezikhukhula.
