EPDM thovu bolodi / pepala kufa kudula PAD / gasket
1. Kukana kwambiri kukalamba
Kukaniza kwabwino kwa ozoni - EPDM imadziwika kuti "rabara yosang'ambika", ndipo ili ndi kukana kwa ozoni kwabwino kwambiri pakati pa mphira wofuna zambiri.
B Kukhazikika kwamafuta abwinoko.
C Kukana kukalamba kwabwino kwambiri - kumatha kugwiritsidwa ntchito kwa nthawi yayitali pa 130 ℃, ndipo kumatha kugwiritsidwa ntchito pafupipafupi kapena kwakanthawi kochepa pa 150 ℃ kapena kutentha kwambiri.
D Kukana kwanyengo kwabwino - kumatanthawuza kukalamba kwa zinthu zophatikizika za kuwala, kutentha, kuzizira, mphepo, mvula, ozoni ndi okosijeni m'chilengedwe.
2. Kukaniza kwabwino kwa mankhwala: Chifukwa cha kukhazikika kwa mankhwala komanso kusakhala ndi polarity ya EPDM yokha, sichimakhudzidwa ndi mankhwala ndi mankhwala ambiri, ndipo sagwirizana kapena sagwirizana pang'ono ndi zinthu za polar.Imalimbana ndi mowa, ma acid (formic acid, acetic acid), maziko amphamvu, oxidants (monga H2O2, HCLO, etc.), zotsukira, mafuta a nyama ndi masamba, ketoni, mafuta ena, ndi hydrazine.
3. Kukaniza kwamadzi kwabwino, kukana kutenthedwa ndi kutentha kwa madzi: madzi ndi chinthu cholimba cha polar, ndipo mphira wa EPDM ndi mtundu wa macromolecular alkanehydrazine ndi "hydrophobicity".Palibe kuyanjana kwamankhwala pakati paziwirizi, kotero imakhala ndi kukana kwambiri kwamadzi, kukana kutentha kwambiri komanso kukana kwa nthunzi wamadzi.
Zinthu zakuthupi za EPDM
Zogulitsa za EPDM mphira thovu siponji: Chogulitsacho chimagawidwa kukhala chotsekedwa-maselo ndi thovu lotseguka.Selo lamkati lazinthu zotsekedwa za thovu zimasiyanitsidwa ndi selo ndi filimu ya khoma, yomwe siili yogwirizana.Ndi cell yodziyimira payokha, ndipo chachikulu Ndi cell yaing'ono kapena yaying'ono kwambiri;maselo amkati a zinthu za thovu lotseguka amalumikizana wina ndi mnzake, ndipo amalumikizidwanso ndi khungu lakunja, lomwe silili lodziyimira pawokha la cell, makamaka ma cell akuluakulu kapena mabowo olimba.
Ma cell otsekedwa: kukana kwanyengo kwabwino;kachulukidwe kakang'ono kachulukidwe, mphamvu yayikulu yamisozi;otsika matenthedwe madutsidwe;mayamwidwe kugwedezeka kwabwino.
Zinthu zotsegulira: kukana kwambiri kwanyengo;kutentha kwambiri kukana, kukana kwabwino kwa kutentha kochepa;kuteteza kutentha, kutentha kwabwino;kukana mafuta polar, kukana mankhwala;kukana kwamadzi kwapamwamba kwambiri, kuyamwa kwabwino kwamawu.
Zipangizo zamaselo otsekedwa: zomwe zimagwiritsidwa ntchito ponyamula zida zolondola, zida zamankhwala, zitseko zamagalimoto ndi zisindikizo zazenera, zotengera mawu a injini ndi zida zowopsa;air-conditioning, kusindikiza firiji ndi zipangizo zotetezera kutentha.Zipangizo zotulutsa mawu zamakhoma, zosanjikiza mpweya komanso zosalowa madzi pazinthu zamagetsi.
Kutsegula zinthu: Monga mkulu kalasi kutchinjiriza matenthedwe, mayamwidwe mantha, mawu mayamwidwe zakuthupi, ntchito magalimoto, zoziziritsa kukhosi, zamagetsi, zomvetsera nyumba, misewu, milatho ndi zina.
EPDM EPDM mphira ali wabwino kukana nyengo, kukana kutentha, kukana kukalamba, damping kusindikiza ndi makhalidwe ena, ndipo angagwiritsidwe ntchito chapakati mpweya, refrigeration unit kutchinjiriza mapaipi, zotchinga zotchinga, mayamwidwe phokoso ndi kuchepetsa phokoso ndi zina.
