Deep trench ball roba bearing POM626 masana'antu kai tsaye tallace-tallace, POM (polyformaldehyde resin) ma'anar: polyformaldehyde ne wani layi irin polymer ba tare da gefen sarkar, high yawa, high crystalline. Dangane da bambancin tsarin sinadarai a cikin sarkar kwayoyin halitta, ana iya raba shi zuwa formaldehyde monopoly da formaldehyde copolymer biyu. Babban bambanci tsakanin biyu shine: monopolyformaldehyde yawa, crystallinity, narkewa maki ne duka high, amma zafi kwanciyar hankali m, aiki zazzabi kewayon ne m (kimanin 10 ℃), ga acid-alkali kwanciyar hankali kadan ƙasa; Kuma copolymer formaldehyde yawa, crystallinity, narkewa maki, ƙarfi ne low, amma zafi kwanciyar hankali ne mai kyau, ba sauki rushe, aiki zazzabi kewayon (kimanin 50 ℃), mafi kyau ga acid-alkali kwanciyar hankali. Yana injiniya roba tare da kyakkyawan hadaddun kaddarorin. Yana da kyakkyawan jiki, inji da sinadarai kaddarorin, musamman da kyakkyawan friction juriya kaddarorin. Ana sanin shi da karfe ko karfe, shi ne na uku mafi girma injiniya roba. dace da yin lalacewa tsayayya sifili.
Ana da mafita daban-daban na kayan kwalliyar roba mai juriya ga waɗanda ke da yanayin aikace-aikace daban-daban, har ma a cikin mafi tsananin acid / alkali / gishiri / mai narkewa / man fetur / gas / ruwan teku, don tabbatar da kyakkyawan juriya da tsammanin rayuwa. Anti-acid alkali filastik bearings, HDPE, PE, UHMWPE da sauran kayan sun tabbatar da cewa za a iya amfani da kwarara yanayi na daidai rauni acid alkali (30% CuCl2 mafita da 30% NaOH mafita gwaji OK), PVDF da PTFE kayan da za a iya amfani da su a karkashin karfi acid alkali yanayi, PTFE a cikin wadannan kayan za a iya amfani da su a duk concentrated acid da kuma concentrated alkali lokuta, har ma da HF da kuma hayaki sulfuric acid nitric acid (sama da 98%) da sauran karfi acid yanayi.
