He aha te Waea purerehua mahi teitei?

Ko te rewharewha o te purerehua mahi teitei he hua hoahoa whakahiato rua hou me te hangarau o te ao.He hanganga ahurei tenei reera rewharewha me te mahi hiri tino pono, nga tikanga mahi whanui me te taipana mahi iti.

Rererererererere rereke rua, me te mowhiti hiri kua oti te whakanoho ki te pereti uhi, Ka noho te takirere he mata whakatika kore mutu ki runga i te porowhita, ka kore te takirere i pa ki te nohoanga i te wa e tuwhera katoa ana.Ma tenei hoahoa ka iti ake te waku o te nohoanga, ka roa ake ai tona oranga.I roto i te tono noa, ka herea te reanga rewharewha toenga-rua ki te karaehe 150.

Ko te mowhiti hiri a te rewharewha he mea hanga mai i te elastomer e uru ana ki roto i te kōpae, ka taea te whakamahi i roto i te tono hiri kotahi, e whakamahia ana i roto i te wai, i te tono wai taone ranei.

Main feautres oWaea pūrerehua mahi teitei:

He roa ake te ora o te mahi na te kopae tio

Ka tukuna te taumahatanga i runga i te kōpae i muri i etahi nekehanga o te whakatuwheratanga ka iti te mau o te hiri o te kōpae.I tua atu, ka whakaitihia e te hoahoa te pupuhi o te hiri e whakarite ana i nga taimana whakahaere iti.

Nga hoahoa nohoanga takirua

Ko te hoahoa o te tuuru whakauru he tuuru rino ductile whakakikoruatia me te epoxy kua whakauruhia ki roto i te tinana.Ko te hoahoa nohoanga kowiri tira he mowhiti nohoanga ka taea te whakakapi o te kowiri tira hiri ki te O-mowhiti kia kore ai e pakaru i raro i te mowhiti nohoanga.

Nga ahuatanga hoahoa o te rakau

Ko te hiri o te rakau ka taea te whakakapi i raro i te pehanga kia ngawari te tiaki.Ko nga hiri o te EPDM he whakamarumaru mai i roto me waho, me nga hiri NBR hei tiaki i nga poke me nga wai o waho.

He hiri kōpae kua arotauhia mo te mahi teitei

Ko te hiri o te kōpae he mea hanga kia mau te whakatika i te tuunga tika e whakarato ana i te mahi tino pono.Ko te kounga pai o te rapa ka taea te whakaiti i te nui o te rapa e whakarite ana i nga taipana kati iti.Ko te hiri EPDM kua whakaaetia e ACS me WRAS.
