Chii chinonzi EPDM zvinhu? -Kuongorora kwakadzama kwehunhu uye mashandisirwo eEPDM rubber
EPDM (ethylene-propylene-diene monomer) irabha rekugadzira rine mamiriro ekunze akanaka, ozone uye makemikari kuramba, uye rinoshandiswa zvakanyanya mumotokari, kuvaka, zvemagetsi nemamwe maindasitiri. Usati wanzwisisa kuti EPDM inogadzirwa nei, zvinodikanwa kuti unzwisise iyo yakasarudzika mamorekuru chimiro uye maitiro ekugadzira kuitira kuti unzwisise zviri nani zvivakwa uye mashandisiro ayo.
1. Mushonga wemakemikari uye chimiro chemakemikari eEPDM
EPDM rubha inowana zita rayo kubva kune ayo makuru ezvikamu: ethylene, propylene uye diene monomers. Aya monomers anoumba elastic polymer cheni kuburikidza necopolymerization maitiro. Ethylene uye propylene inopa yakanakisa kupisa uye oxidation kuramba, nepo diene monomers inobvumira EPDM kuyambuka-yakabatana nevulcanisation kana peroxide, ichiwedzera kuwedzera kusimba uye kusimba kwechinhu.
2. Zvinhu zvakakosha zvekushanda kweEPDM
Pamusana pekugadzirwa kwayo kwemakemikari akasiyana-siyana, EPDM ine zvinhu zvakasiyana-siyana zvakanaka zvinoita kuti ionekwe munzvimbo dzakasiyana-siyana.EPDM ine mamiriro ekunze akanaka uye UV inopikisa, izvo zvinoreva kuti inokwanisa kuvhenekerwa nechiedza chezuva kwenguva yakareba. pasina kuora.EPDM inewo yakanakisa ozone kuramba, iyo inobvumira kuchengetedza kushanda kwayo mumamiriro ezvinhu akaoma ezvakatipoteredza pasina kuputika.
Chimwe chinhu chakakosha ndechekupikisa kwemakemikari, kunyanya kune acids, alkalis uye zvakasiyana-siyana zvinonyungudutsa polar. Nokudaro, EPDM inowanzoshandiswa mumamiriro ezvinhu anoda nguva refu kumakemikari.EPDM ine huwandu hwakawanda hwekushisa kwekushanda, uye inogona kushanda kazhinji pakati -40 ° C uye 150 ° C, iyo inoita kuti inonyanya kushandiswa mumotokari. indasitiri, sezvisimbiso zvemahwindo, mahosi eradiator, nezvimwe.
3. EPDM zvikumbiro mumaindasitiri akasiyana-siyana
Kushandiswa kwakapararira kweEPDM kunonzi kunokonzerwa nekusiyana-siyana uye kunaka kwemuviri. Muindasitiri yemotokari, EPDM inowanzoshandiswa mukugadzira zvidhindo, zvisimbiso zvemagonhi, mawipers ewindscreen nemapombi eradiyeta. Nekuda kwekupisa kwavo uye kuramba kuchembera, zvikamu izvi zvinochengeta elasticity uye kushanda kwayo kwenguva yakareba, zvichivandudza hupenyu hwebasa remotokari.
Muindasitiri yekuvaka, EPDM inoshandiswa zvakanyanya padenga rekuvhara mvura, masuo nemahwindo zvisimbiso uye mamwe maapplication anoda kudzivirira mvura uye UV kushorwa. Kuramba kwayo kwakanaka kwemamiriro ekunze uye kushanduka kwemamiriro ekunze kunovimbisa kugadzikana kwemaitiro uye kuiswa chisimbiso kwezvivako.EPDM inoshandiswawo mune sheathing zvinhu zvewaya uye tambo, zvichipa yakanakisa magetsi ekudzivirira kushanda uye kupikisa kwemakemikari.
4. EPDM kuchengetedza kwezvakatipoteredza uye kusimudzira kwakasimba
Mumamiriro ezvinhu aripo ekuwedzera kuomesera kwekuchengetedza kwezvakatipoteredza zvinodiwa, EPDM inewo hanya nekuda kwekuchengetedzwa kwayo kwezvakatipoteredza uye inogoneka budiriro inogona. EPDM chinhu chinodzokororwa, maitiro ekugadzira haanyanye kukuvadza magasi nemarara, zvinoenderana nezvinodiwa nenzanga yanhasi yekuchengetedzwa kwezvakatipoteredza. Kuburikidza nekuenderera mberi kwekuvandudzwa kwemaitiro ekugadzira, simba uye zviwanikwa zvekushandisa zveEPDM zviri zvakare kuderedzwa zvishoma nezvishoma, zvichibatsira mukusimudzirwa kwakasimba kweindasitiri.
Mhedziso
Chii chinonzi EPDM zvinhu? Iyo yakagadzirwa nerabha zvinhu zvine hunyanzvi hwekuita uye huwandu hwakawanda hwekushandisa. Nekupokana kwayo kwemamiriro ekunze, kushomeka kwemakemikari uye kushamwaridzana kwezvakatipoteredza, inoita basa rakakosha mumaindasitiri akasiyana. Ingave muindasitiri yemotokari, indasitiri yekuvaka, kana minda yemagetsi nemagetsi, EPDM yave sarudzo yakakosha yezvinhu nekuda kwekuita kwayo kwakanaka.
