I-NBR (i-nitrile rubber) kunye ne-EPDM (i-ethylene propylene diene monomer) umahluko wezinto eziphathekayo!

I-NBR inokumelana neoli efanelekileyo, i-EPDM ihlwempuzekile ekuchaseni i-oyile kwaye ayihlali ixesha elide, kodwa inokuxhathisa ukuguga kunye nokushisa.Ngokuqhelekileyo, i-EPDM isetyenziswa kakhulu kwimibhobho yamanzi nangaphezulu komphunga;I-EPDM ingcono kwi-friction resistance.
1. I-Nitrile irabha ye-NBR yirabha ye-polar unsaturated carbon chain, efakwe kwi-acrylonitrile kunye ne-butadiene.Ngokuxhomekeke kumxholo we-acrylonitrile ukusuka kwi-low ukuya phezulu, ukuxhathisa kweoli kuphuculwe, kodwa ukuchasana nokubanda kuyancipha.
Ukumelana ne-oyile lolona phawu lukhulu lwerabha ye-nitrile ye-NBR, enokumelana kakuhle ne-oyile esekwe kwi-petroleum kunye nezinyibilikisi ezingekho phantsi kwe-polar, kodwa ukunganyangeki kakuhle kwi-oyile ye-polar kunye nezinyibilikisi ze-polar.
1. Ipropathi elungileyo ye-antistatic;
2. Ukunganyangeki kwe-ozone;
3. Inokuhambelana kakuhle kunye nezixhobo ze-polar, ezifana ne-polyvinyl chloride (PVC), i-polyoxymethylene (i-POM), i-nylon, kwaye ingenziwa kwi-rubber kunye neplastiki.
4. Uluhlu lweqondo lokushisa elisebenzayo lerabha ye-nitrile eqhelekileyo: -20 ° C ~ 120 ° C, kunye neentlobo eziphantsi kweqondo lokushisa zingaba ngaphantsi kwe -50 ° C;
2. Irabha ye-ethylene-propylene isebenzisa i-ethylene kunye nepropylene njengezinto eziluhlaza zokwenziwa, kwaye zinokwahlulwa zibe yi-binary ethylene-propylene rubber (EPM) kunye ne-tertiary ethylene-propylene rubber (EPDM).

Iimpawu zerabha ethylene propylene:

1. Ukumelana nokuguga kweOzone

2. Ukumelana nemozulu

3. Ukumelana nobushushu
Ezi zakhiwo zintathu zingentla zezona zibalaseleyo kwirabha ngokubanzi.Kukwakho ezi propati zilandelayo
4. Ukuchasana kwamanzi okugqwesileyo, ukumelana nobushushu obuphezulu kunye nokumelana nomphunga wamanzi;

5. Ukuchasana kweekhemikhali okugqwesileyo;
(Ngenxa yokuzinza kweekhemikhali kunye ne-non-polarity yerabha ye-ethylene-propylene ngokwayo, ayisebenzi ngokwekhemikhali kunye neekhemikhali ezininzi, ayihambelani okanye ayinakuhambelana okuncinci kunye nezinto ze-polar, kwaye iyamelana notywala, i-asidi, i-alkali enamandla, i-oxidizing. ii-agent, ii-agent zokuhlamba, i-oyile yezilwanyana kunye nemifuno, ii-ketones, njl.)
I-NBR ithambile, i-EPDM ilukhuni kancinane kwaye inencasa eyahlukileyo

1. Amanqaku aqhelekileyo erabha
(1) Irabha ngokubanzi: njenge-NR/BR/SBR/EPDM
(2) Irabha ekhethekileyo: njenge-SR/FPM/CIIR/HNBR/CSM 2.

I-Nitrile irabha i-NBR inokumelana ne-oyile elungileyo, eyaziwa ngokuba yirabha yobungqina be-oyile, kwaye ihlala isetyenziswa njengetywina leoli.
Irabha yendalo i-NR ine-elasticity elungileyo kunye nokusebenza kakuhle ngokubanzi, kodwa ukunganyangeki okubandayo kunye nokuxhathisa kwealkali.Idla ngokusetyenziswa njengamatayara emoto
I-Styrene Butadiene Rubber SBR Eyona rabha inexabiso eliphantsi emhlabeni, isetyenziswa njenge pad
I-EPDM inokumelana ne-corrosion elungileyo kunye nokugquma okulungileyo, kwaye inokusetyenziswa njengezinto ezinganxibiyo okanye izixhobo zombane eziphezulu.
I-Neoprene CR inokumelana nokunxiba kakuhle kwaye inokusetyenziswa njengecushion I-Chlorosulfonated polyethylene CSM inokumelana nokubanda okuhle.
Polytetrafluoroethylene PTFE
Inkosi yePlastiki, i-asidi egqwesileyo kunye nokumelana ne-alkali, inokumelana ne-hydrofluoric acid.Inoluhlu olubanzi losetyenziso kwaye inokusetyenziswa njengombhobho wolwelo oludlekayo.

I-Hebei CONQI VEHICLE FITTINGS Co., Ltd. yinkampani ezinikele ekuveliseni nasekusasazeni umbhobho werabha we-auto, umbhobho we-EPDM, i-hose yebakala lokutya kunye ne-pvc hose njl njl kunye namava okuvelisa acebileyo, iteknoloji yemveliso ephezulu kunye nenkqubo epheleleyo kunye nesayensi yokulawula umgangatho.Ngo-2009, inkampani yagqiba ixabiso lemveliso ye-yuan yezigidi ezili-10.01 kwaye yagqiba irhafu ye-250, 000 ye-yuan.Zonke zihambelana nee-OEM zasekhaya ezingaphezu kwama-30 ezinje ngeJinlong, Yutong, Ankai, kunye neZhongtong, kunye namasebe aphesheya kweVolvo kunye neIndiya, New Zealand, Thailand, Taiwan, Poland, Israel, Britane, Egypt, Spain, Turkey, IBrazil, iSingapore, iJamani kunye namazwe angaphezu kwama-20 kunye nemimandla ifumene izibonelelo ezixhasayo.Ukubambelela kumgaqo "wophuculo oluqhubekayo, ukugqwesa, umgangatho obalaseleyo, kunye nokwaneliseka kwabathengi", sithatha ngokunyanisekileyo itekhnoloji yamva nje yezizwe ngezizwe kunye nolwazi lwemveliso, siyila rhoqo kwaye siphuhlisa iimveliso ezintsha, kwaye sibonelela abathengi.
