EPDM (Ethylene propylene diene monomer) rubber
EPDM rubberni kopolymer ya Ethylene, propylene hamwe na bike bya monomer ya gatatu idafite conjugated diene.Izina mpuzamahanga ni: Ethyiene Propyene Diene Methyiene, cyangwa EPDM muri make.Rubber ya EPDM ifite ibyizaKurwanya UV, kurwanya ikirere, kurwanya gusaza ubushyuhe, kurwanya ubushyuhe buke, kurwanya ozone, kurwanya imiti, kurwanya amazi, kubika amashanyarazi neza no gukomera., nibindi bintu bifatika nubukanishi.Izi nyungu ntizishobora gusimburwa nibindi bikoresho byinshi.
1. Kurwanya ikirereifite ubushobozi bwo guhangana nubukonje bukabije, ubushyuhe, umwuma nubushuhe mugihe kirekire, kandi ifite imbaraga zo kurwanya ruswa irwanya isuri yurubura namazi, bishobora kongera ubuzima bwumurimo wimiryango, amadirishya nurukuta rwumwenda.
2. Ubushyuhe bwo gusaza bivuze ko bufite imbaraga zo kurwanya gusaza kwikirere.Irashobora gukoreshwa kuri -40 ~ 120 ℃ igihe kirekire.Irashobora kandi kugumana ibimenyetso bifatika mugihe kirekire kuri 140 ~ 150 ℃.Irashobora kwihanganira ubushyuhe bwo hejuru bwa 230 ~ 260 ℃ mugihe gito.Irashobora kugira uruhare mukwubaka imijyi.Ingaruka zo gutinda;bifatanije no gukoresha formula idasanzwe,EPDM rubberifite imyumvire isa kuva kuri -50 ° C kugeza kuri 15 ° C.Iyubakwa ryikibanza cyo gukora ryashizeho ibisubizo bihanitse.
3. KuberakoEPDMifite ozone nziza cyane, izwi kandi nka "rubber-crack".Ikoreshwa cyane cyane mumyubakire itandukanye yo mumijyi ifite ibipimo bitandukanye byikirere kandi ihura nikirere rwose.Bizerekana kandi ibicuruzwa birenze.
4. Kurwanya imirasire ya ultraviolet bitanga kurengera ibidukikije kubakoresha inyubako ndende;irashobora kwihanganira voltage 60 kugeza 150Kv, kandi ifite imbaraga nziza zo kurwanya corona, kurwanya amashanyarazi, hamwe no kurwanya arc.Ubushyuhe buke buke, ubushyuhe iyo ubushobozi bwa tensile bugera 100MPa ni -58.8 ℃.
5. Bitewe nuburyo bwiza bwihariye bwubukanishi, bukoreshwa kenshi mugukora indege, imodoka, gariyamoshi, bisi, amato, akabati yo hejuru ya voltage nini yo hejuru, urukuta rwumwenda wikirahure, aluminiyumu alloy yumuriro wubushyuhe bwo gufunga ibice nibicuruzwa byo kwibira, Umuvuduko ukabije wamazi yoroshye Imiyoboro, tunel, guhuza viaduct nibindi bice bitarinda amazi nibindi bice bifunga inganda nubuhinzi.

1. Bitewe nibyiza biranga imiterere yarubber, ifite ubushobozi bwo kugumya gutuza neza mugihe runaka nubushyuhe runaka.Ugereranije nabandi bakorana na sintetike, reberi ya silicone irashobora kwihanganira ubushyuhe burenze urugero -101 kugeza 316 ° C kandi bikagumana imiterere-karemano.
2. Indi mico idasanzwe yiyi elastomer yisi yose:kurwanya imirasire, ingaruka nkeya ziterwa no kwanduza;Kurwanya kunyeganyega, hafi yo guhererekanya hafi na resonance inshuro kuri -50 ~ 65 ° C;guhumeka neza kurenza izindi polymers Umutungo;imbaraga za dielectric 500V · km-1;igipimo cyo kwanduza <0.1-15Ω · cm;kurekura cyangwa gukomeza gukomera;ubushyuhe bwo gukuraho 4982 ° C;umunaniro muke nyuma yo guhuza neza;byoroshye gusaba gukurikiza amategeko agenga ibiryo kuzuza ibiryo;ibirimi by'umuriro;ibicuruzwa bitagira ibara kandi bidafite impumuro birashobora kubyazwa umusaruro;ibikoresho bidafite amazi;ubudahangarwa bwa physiologique bwuburozi butanu hamwe nubuvuzi.
3. Rubberirashobora gukorwa mubicuruzwa byamabara atandukanye ukurikije ibyo abakiriya bakeneye nibisabwa mubuhanzi.

3. TPV / TPE thermoplastique elastomer
Thermoplastique elastomer ifite imiterere nubukanishi bwa reberi yibirunga hamwe nibikorwa bya plastiki yoroshye.Ni ahantu hagati ya plastiki na reberi.Kubijyanye no gutunganya, ni ubwoko bwa plastiki;ukurikije imitungo, ni ubwoko bwa reberi.Thermoplastique elastomers ifite ibyiza byinshi kurenza reberi ya thermoset.
1. Ubucucike bwo hasi bwa thermoplastique elastomer(0.9 ~ 1.1g / cm3), bityo uzigame ibiciro.
2.Guhindura hasihamwe no kunanirwa kunanirwa kunanirwa.
3. Irashobora gusudira cyane kugirango itezimbere inteko no gufunga.
4. Ibikoresho by'imyanda (guhunga burrs, ibikoresho byo guta imyanda) hamwe n’ibicuruzwa byanyuma biva mu gihe cy’umusaruro birashobora gusubizwa mu buryo butaziguye kugira ngo bikoreshwe, bigabanye umwanda w’ibidukikije ndetse no kwagura umutungo w’ibicuruzwa.Nibintu byiza byatsi kandi bitangiza ibidukikije.
