Ukoliko bi točkovi došli u kontakt sa agresivnim supstancama, njihova otpornost na hemikalije mora se uzeti u obzir prilikom odabira pravog proizvoda.
Analiza otpornosti na hemikalije
Ako postoji mogućnost da točkovi dođu u kontakt sa agresivnim supstancama, njihova optornost na hemikalije mora se uzeti u obzir kada se biraju odgovarajući proizvodi. Što bolje znamo uslove okruženjau kojima će biti korišteni točkovi ili točkići , to preciznije možemo da utvrdimo koji proizvod će biti najpogodniji. To može pomoći da se spreči prerano kvarenje zbog korozije, promena na površini, gubljenja žilavosti, gubitka jačine, ili curenje lubrikanta. Pažljiva koordinacija svih komponenti garantuje maksimalan životni vek.
Važni faktori u hemijskoj otpornosti
Na početku treba proveriti koje su hemijske supstance i uticaji na životnu sredinu prisutni na mestu upotrebe. Važno: Reakcija materijala zavisi od različitih faktora, kao što su vreme kontakta i koncentracija agresivnih supstanci, kao i vlažnost i temperatura. Pravi se razlika između supstanci koje su hemijski otporne, delimično otporne ili nisu otporne. Dobru hemijsku otpornost pokazuju čelični nerđajući lim, plastika i termoplastična guma.
U tabeli ćete videti pregled hemijske otpornosti naših materijala na različite agresivne supstance. Vrednosti prikazane u tabeli samo su smernice i ne primenjuju se na mešavine hemikalija. Molimo vas da nas kontaktirate u posebnim slučajevima, rado ćemo vam pružiti detaljne savete!
