Imiyoboro hamwe na Coatings yo kurwanya ruswa
Ibicuruzwa Intangiriro
Ibipimo: Ibipimo ngenderwaho byo kurwanya ruswa byashyizweho n’imiryango nka Sosiyete y'Abanyamerika ishinzwe ibizamini n’ibikoresho (ASTM), Umuryango mpuzamahanga wita ku bipimo ngenderwaho (ISO) hamwe n’umuryango w’igihugu gishinzwe inganda za ruswa (NACE). Ibipimo ngenderwaho byerekana ibisabwa kubikoresho byo gutwikira, uburyo bwo gusaba, inzira yikizamini hamwe nubuziranenge.
Ibyiciro bishingiye ku kuvura hejuru: Imiyoboro ifite anti-ruswa ishobora gutondekwa hashingiwe ku bwoko bwa coating yakoreshejwe. Ibyiciro bisanzwe birimo: Fused Bonded Epoxy (FBE) Coating Polyethylene (PE) cyangwa polypropilene (PP) itwikiriye Asphalt cyangwa asifalti Zinc ikungahaye kuri Zinc irangi ryuzuye Polyurethane gutwika Amakara yamashanyarazi.
Porogaramu: Imiyoboro ifite imiti irwanya ruswa ikoreshwa cyane mu nganda zitandukanye, zirimo: Amavuta na gaze: Imiyoboro ikoreshwa mu gutwara peteroli, gaze gasanzwe n’ibikomoka kuri peteroli Amazi n’amazi mabi: ku mazi y’ubutaka n’imyanda Imiti na peteroli: mu gutwara imiti yangiza na acide Marine no ku nkombe: ku miyoboro yo mu nyanja n’inyubako zo mu nyanja Ibikorwa Remezo: Kugira ngo ukoreshwe ku biraro, ku kivuko no ku zindi nyubako zugarijwe n’ibidukikije bikabije Iyi miyoboro ni ingenzi mu gukomeza ubusugire no kuramba by’ibikorwa remezo bikomeye na sisitemu y’inganda, cyane cyane mu bidukikije cyangwa byangirika. Mugihe cyo kwerekana cyangwa guhitamo umuyoboro ufite igipande kirwanya ruswa, ni ngombwa kwifashisha ibipimo bifatika no kugisha inama impuguke mu nganda kugirango hamenyekane ko igifuniko cyatoranijwe cyujuje ibisabwa byihariye bisabwa.
