Ikiganiro ku guhitamo gasike ya flange (I)

  Rubberikwiranye namazi, amazi yinyanja, umwuka, gaze ya inert, alkali, igisubizo cyamazi yumunyu nibindi bitangazamakuru, ariko ntibirwanya amavuta yubutare hamwe nudukoko twa polar, ubushyuhe bwigihe kirekire ntibukoresha 90 ℃, imikorere yubushyuhe buke nibyiza , irashobora gukoreshwa hejuru -60 ℃.

  Nitrile rubberibereye ibikomoka kuri peteroli, nka peteroli, amavuta yo gusiga, amavuta ya lisansi, nibindi, ubushyuhe bwigihe kirekire bwo gukoresha ni 120 ℃, nko mumavuta ashyushye arashobora kwihanganira 150 ℃, ubushyuhe buke ni -10 ~ -20 ℃.

  Rubberikwiranye n’amazi yo mu nyanja, aside idakomeye, alkali idakomeye, igisubizo cyumunyu, kurwanya cyane ogisijeni na ozone gusaza, kurwanya amavuta ni munsi ya reberi ya nitrile kandi nziza kuruta izindi reberi rusange, gukoresha igihe kirekire ubushyuhe buri munsi ya 90 ℃, ubushyuhe bwinshi bwo gukoresha ntabwo kurenga 130 ℃, ubushyuhe buke ni -30 ~ -50 ℃.

Hariho ubwoko bwinshi bwarubber, zifite aside irwanya neza, irwanya okiside hamwe n’amavuta, irwanya solvent. Irashobora gukoreshwa mubitangazamakuru hafi ya acide kimwe namavuta hamwe na solve, gukoresha igihe kirekire gukoresha ubushyuhe buri munsi ya 200 ℃.

Urupapuro rwa reberi nk'igikoresho cya flange, gikoreshwa cyane cyane mu miyoboro cyangwa akenshi gisenywa manholes, imyobo y'intoki, igitutu ntikirenza 1.568MPa. Kuberako muburyo bwose bwa gasketi, reberi ya reberi niyo yoroshye, imikorere myiza yo guhuza, kandi irashobora gukina kashe munsi yingufu ntoya mbere yo gupakira. Kubera iyo mpamvu, iyo uhuye nigitutu cyimbere, biroroshye gusunikwa kubera ubunini cyangwa ubukana buke bwa gaze.

Urupapuro rwa reberi rukoreshwa muri benzene, ketone, ether hamwe nandi mashanyarazi kama, byoroshye kugaragara kubyimba, kwiyongera ibiro, ibintu byoroshye, bifatanye, bikaviramo kunanirwa kashe. Mubisanzwe, niba urwego rwo kubyimba rurenze 30%, ntirushobora gukoreshwa.

Mugihe cyumuvuduko muke (cyane cyane munsi ya 0,6MPa) na vacuum, gukoresha reberi birakwiriye. Ibikoresho bya reberi bifite ubucucike bwiza kandi bworoshye. Kurugero, reberi ya fluor ikwiranye cyane no gufunga gasketi yibikoresho bya vacuum, naho impamyabumenyi ya vacuum igera kuri 1.3 × 10-7Pa. Iyo reberi ikoreshwa murwego rwa vacuum ya 10-1 ~ 10-7Pa, igomba gutekwa no kuvoma.
