Valve yokhala ndi mphira ya butterfly

Mavavu agulugufe okhala ndi mphira odalirika kwambiri, opangidwa molimba molingana ndi momwe zinthu zilili pozungulira.

Ebonite akalowa: ali wabwino kukhazikika kwa mankhwala, kwambiri mankhwala dzimbiri kukana ndi organic zosungunulira kukana, otsika mayamwidwe madzi, mkulu wamakomedwe mphamvu ndi kwambiri kutchinjiriza magetsi etc.features.

Mzere wa ebonite umapanga chivundikiro chosalekeza pa gawo lapansi ndikuwonjezera mapangidwe apadera ndi ndondomeko ya olowa kuti athetseretu gawo lapansi lachitsulo kuchokera kumalo ochitira utumiki, motero kuonetsetsa kuti nthawi yayitali ya ntchitoyo.Pamadzimadzi amadzimadzi amadzimadzi, ikhala njira yotsika mtengo kwambiri.

Malo oti atetezedwe ndi lining ebonite adzakhala mchenga wophulika kuti uwonetsere zitsulo zoyera ndi kufika paukhondo Sa 2.5 mpaka ISO 8501 ndi roughness medium G kufika ISO 8503.

Pansi pa chilengedwe chokhala ndi chinyezi chosapitilira 60% ndi kutentha kwa 15-40 ℃, gwiritsani ntchito zida zomangira zomangira monga kuthamanga kwa roller ndi scraper kuti mugwirizanitse pepala la rabala ndi gawo lapansi molingana ndi njira ndi zofunikira.

Vulcanization ya ebonite yokonzedwa ndi mpweya wotentha kapena nthunzi mu ketulo yowotchera.

Zotsatirazi zitha kungoyambika mutapambana mayeso osiyanasiyana ndikuwunika (kuyang'ana m'maso, kudziwika kwa spark yamagetsi kutchuthi / mapini / ming'alu, kuyesa kwa adhesion ndi kuyesa kuuma etc.)

Mtundu wowuma udzafika Shore D 75±5

Chitetezo cha kunja kwa dzimbiri: njira zotsatirazi zopenta zimaperekedwa kuti zigwirizane ndi kagwiritsidwe kagawo ka C5 corrosivity malinga ndi EN ISO 12944-2,

Epoxy zinc woyambira wolemera - 60μm, Epoxy micaceous iron / utoto wapakatikati - 120μm, Acrylic polyurethane finish paint - 60μm, Total youma kudzaza makulidwe (DFT) 240μm

Epoxy glass flake primer- 80μm, Epoxy glass flake paint two layer - 160μm, Total youma kudzaza makulidwe (DFT) 240μm

Zomangira zonse zamkati ndi zakunja monga mtedza, mabawuti, zomangira ndi zomangira ziyenera kukhala zachitsulo chosapanga dzimbiri giredi 316L kapena duplex chitsulo chosapanga dzimbiri.

Mavavu agulugufe okhala ndi mphira onse oyenera kukhazikitsidwa molunjika kapena mopingasa.

Diso lonyamulira / ndowe yonyamulira yokhazikika pamalo oyenera kuti valavu ikwezedwe moyima kapena yopingasa.
